PURPOSE: To investigate the functional and structural characteristics of temporomandibular joint(TMJ) in introverted deep overbite patients with severe wear, to analyze the correlation between the vertical distance of the lower 1/3 of the face and TMJ space, and to compare the clinical efficacy of multidisciplinary treatment with orthodontics and prosthodontics on TMJ function. METHODS: Eighty patients with deep overbite and severe abrasion and forty subjects with normal occlusion admitted to our hospital from January 2019 to June 2023 were enrolled in this study. The clinical data were collected and the functional and structural characteristics of TMJ were collected. Eighty patients with deep overbite and severe abrasion were randomly divided into control group and experimental group, with 40 cases in each group. The control group was treated with restoration, and the experimental group was treated with orthodontic combined with restoration. The efficacy and CBCT imaging indexes were evaluated during the treatment. SPSS 26.0 software package was used for statistical analysis. RESULTS: The mean Helkimo index of patients with deep overbite and severe abrasion was significantly higher than that of patients with normal occlusion(P＜0.05). CBCT scan showed that anterior space of TMJ in patients with deep overbite and severe abrasion significantly increased than those with normal occlusion(P＜0.05), while superior and posterior space were significantly decreased than those with normal occlusion(P＜0.05). Lateral cephalometric analysis showed that the vertical distance of submaxillofacial 1/3 in patients with deep overbite and severe abrasion significantly decreased than normal occlusion(P＜0.05). The Helkimo index of the two groups after treatment was significantly reduced (P＜0.05), and the Helkimo index of the experimental group was significantly lower than that of the control group (P＜0.05). The anterior TMJ spaces of the two groups significantly decreased after treatment, and the superior and posterior TMJ spaces were significantly increased(P＜0.05), but there was no significant difference in TMJ space between the experimental group and the control group(P＞0.05). The vertical distance of submaxillofacial 1/3 in patients in both groups significantly increased after treatment(P＜0.05). There were correlations between the vertical distance of lower one-third of face and the anterior, superior and posterior TMJ spaces(P＜0.05). CONCLUSIONS: The clinical effect of dual disciplinary treatment of orthodontics and prosthodontics on TMJ function was significantly better than that of prosthodontics alone, and the effect on TMJ structure correction is similar to that of prosthodontics.

PURPOSE: To explore a more effective comprehensive prevention and treatment model for children's oral health by constructing a health network platform that integrates medical information evaluation, interaction, monitoring, and prevention with oral health management as the core. METHODS: The database of Shaoxing Children's Oral Health Management Network Platform was established. The oral health survey and information entry of 7 042 second-grade children in primary school in Yuecheng District from 2021 to 2022 were conducted. An open randomized controlled clinical trial was designed, with 3 472 of 7 042 children randomly assigned to the platform management group and 3 570 to the control group. One year later, oral examinations were conducted again on two groups of children, and the correlation between oral examination indicators between the two groups was statistically analyzed using SPSS 25.0 software package. RESULTS: There was significant difference between the two groups in the mean number of newly added deciduous caries decayed- missing-filled teeth(dmft), deciduous caries decayed teeth (dt), deciduous caries missing teeth(mt), and deciduous caries filled teeth(ft) after one year(P＜0.05). The newly added rates of caries, gingival bleeding, calculus detection, and malocclusion between the two groups were lower in the platform group than in the control group, with a significant difference(P＜0.05). CONCLUSIONS: To the prevention and treatment of oral diseases, intelligence has become more and more indispensable and important. Building a network platform for oral health is an effective way to promote oral health level.

PURPOSE: To evaluate the clinical effect of self-made oral science video on guiding parents to promote oral health of pre-school children, and to explore a more effective new technology in oral hygiene education. METHODS: One hundred and four 3-6 years old children with early childhood caries from Shanghai Xuhui District Dental Center were randomly recruited and divided into intervention group(n=52) and control group (n=52) during July to September 2022. At recruitment and 1 month after recruitment, the control group received routine oral health education, while the intervention group parents watched self-made oral health video and received routine oral health education. Plaque index (PLI), decayed missing filled tooth surface (dmfs) as well as oral health knowledge, attitude, practice(KAP) score of parents were compared between the two groups 1 and 6 months after recruitment.SPSS 26.0 software package was used for statistical analysis of the data. RESULTS: At 1 and 6 months after recruitment, the KAP score of intervention group （86.445±7.156, 85.694±5.880）was significantly higher than that of the control group [82.571(77.286, 88.142)，81.853±7.482]（P＜0.05）. The PLI of intervention group [2.014±0.403, 1.895(1.250, 2.100)] was significantly lower than that of the control group（P＜0.05）. There was no significant difference of dmfs between the intervention group and control group(P＞0.05). CONCLUSIONS: As a new oral hygiene education technology, self-made oral science video is effective on improving oral health condition of pre-school children and the KAP condition of their parents.

PURPOSE: To explore the differences between plaque biofilms of children with different caries activities via metabolomics. METHODS: A case-control study was conducted to investigate the oral health-related behaviors of children in caries-free (CF), low level of early childhood caries(LECC) and high level of early childhood caries (HECC) groups and to collect supragingival plaque biofilms. Untargeted metabolomics was used to detect the compositions of plaque biofilm metabolites in three groups. Orthogonal partial least squares discriminant analysis, volcano plot and heat map were used to analyze the significant differential metabolites between groups with SPSS 26.0 software package. RESULTS: A total of 102 children aged 36 months were included in this study, including 34 children in each group. A total of 660 metabolites belonging to 11 categories were detected. There were statistical differences of 6 metabolites between LECC group and CF group, and 22 metabolites showed statistical differences between HECC group and CF group(P＜0.05). Cys Cys Cys Gln, Cys Gln Cys Cys and 5-O-p-coumaroylnigrumin were the common differential metabolites between children with different levels of dental caries. CONCLUSIONS: There are differences in the compositions of plaque biofilms between children with different caries activities and healthy children. Peptides are important differential metabolites within plaque biofilms, also related to oral health.

PURPOSE: To compare the clinical efficacy of autologous bone block graft and guided bone regeneration (GBR) in horizontal bone augmentation. METHODS: A total of 42 patients were included and divided into two groups. Group A included 20 patients, in whom autologous bone block graft was performed. Group B included 22 patients, in whom GBR was conducted. The incidence of complications, pain degree, secondary bone graft rate, bone width increment, bone resorption rate, marginal bone resorption and implant success rate after 1 year of restoration were recorded and evaluated. SPSS 26.0 soft ware package was used for data analysis. RESULTS: There was no significant difference in implant success rate, incidence of complications and the rate of secondary bone grafting between the two groups. The pain degree in group A was significantly higher than that in group B(P＜0.05). The increment of bone width at 2 mm below the crest in group A was more than that in group B(P＜0.05). There was no significant difference in increment of bone width between 6 mm and 10 mm below the crest. The absorption rate of group A was significantly lower than that of group B at 2 mm below the crest(P＜0.05), while the difference was not statistically significant at 6 mm and 10 mm below the crest. There was no significant difference in marginal bone resorption between the two groups 1 year after restoration. CONCLUSIONS: For horizontal bone defects, autologous bone block graft has a better bone contour at the crest than GBR. The amount of marginal bone resorption in two groups is similar after 1 year of restoration.

PURPOSE: To explore the association between tumor necrosis factor-associated apoptosis-inducing ligand (TRAIL) gene polymorphism and susceptibility to diabetic periodontitis. METHODS: A total of 150 patients with type 2 diabetes were selected from September 2022 to September 2023. The patients were divided into combined group(n=50), non-combined group (n=50) and control group (n=50) according to whether they had periodontitis. Clinical medical records of all subjects were collected, TRAIL G1525A and C1595T gene polymorphisms were detected, and the influencing factors of type 2 diabetic periodontitis were analyzed. Statistical analysis was performed with SPSS 19.0 software package. RESULTS: In combined and non-combined group, the fasting blood glucose(FBG), loss of attachment(AL), gingival crevicular bleeding index (SBI) and blood calcium were significantly lower than those in the control group, and HbA1c and serum alkaline phosphatase(ALP) were significantly higher than those in the control group(P＜0.05). The GG gene frequency of TRAIL G1525A gene in the combined group was significantly higher than that in the non-combined group and control group(P＜0.05). There was no significant difference in genotype distribution of TRAIL C1595T among three groups(P＞0.05).HbA1c, AL, SBI, ALP and TRAIL G1525A polymorphisms were risk factors for periodontitis(P＜0.05). The distribution of TRAIL G1525ALeuGGin with moderate and severe periodontitis was significantly different from that with mild periodontitis (P＜0.05). CONCLUSIONS: TRAIL G1525A gene is associated with the susceptibility of diabetic periodontitis, and GG genotype patients with type 2 diabetes have a higher risk of periodontitis.

PURPOSE: To assess the impact of retrograde dissection of the facial nerve along the mandibular margin on the postoperative quality of life in patients with benign superficial parotid tumors. METHODS: One hundred and sixteen patients who underwent surgical treatment for benign superficial parotid tumors at Qingdao Central Hospital from January 2020 to January 2023 were involved. The patients were randomly allocated into two groups, with 58 patients in each group using the touch ball method.The control group underwent antegrade dissection of the facial nerve during surgery, while the experimental group underwent retrograde dissection along the mandibular margin. Surgical duration, intraoperative blood loss, incision length and hospital stay between the two groups were compared. Postoperative pain levels were recorded at 1, 3, 7 and 14 days after surgery. Chewing function was assessed at 15 days, 1 month, 3 months and 6 months postoperatively. House-Brackmann scale (H-B) and scar cosmesis assessment and rating (SCAR) scale were used to evaluate facial nerve function and aesthetic outcomes at 3 days and 6 months postoperatively. The quality of life of the two groups of patients was compared before and 6 months after surgery. Complications were recorded including temporary facial paralysis, periaural numbness, salivate fistula and Frey syndrome. SPSS 28.0 software package was used for statistical analysis. RESULTS: The operative time of the experimental group was significantly higher than that of the control group, intraoperative blood loss, incision length and postoperative pain score of the experimental group were significantly lower than those of the control group. Masticatory efficiency, facial nerve function, scar aesthetics and quality of life of the experimental group were significantly higher than those of the control group, while the incidence of complications was significantly decreased than those of the control group(P＜0.05). CONCLUSIONS: The use of retrograde dissection of facial nerve along the mandibular marginal branch during surgery for benign parotid gland is helpful to reduce intraoperative blood loss and postoperative pain, and improve patients' quality of life.

PURPOSE: To compare the trueness of the tissue surface of the complete denture base among the digital cutting complete denture, the digital 3D printing complete denture and the conventional complete denture. METHODS: Three edentulous patients were selected, and three complete dentures were made for each case. Cutting dentures (cutting group), 3D printed dentures(printing group) were considered as the experimental groups, traditional dentures (traditional group) were considered as the control group. The tissue surface of complete denture model and denture base were scanned and their 3D data were obtained. Geomagic software was used to fit the model information with the tissue surface information of the denture base. A total of 8 regions were selected in the upper and lower complete dentures, and 10 points were randomly selected in each region. The average value of the absolute deviation value(Dm) of each region was calculated. SPSS 22.0 software package was used to analyze the Dm in a total of 24 regions of the three pairs of dentures. RESULTS: The absolute mean deviation was (0.056±0.025) mm in the cutting group, (0.103±0.038) mm in the printing group, and (0.096±0.039) mm in the traditional group, which were significantly different among the three groups(P＜0.05). The trueness of the ablation group was better than that of the conventional group, and the difference was significant (P＜0.05). The trueness of the printing group was worse than that of the traditional group, and the difference was not significant(P＞0.05). CONCLUSIONS: The trueness of cutting dentures is better than that of traditional dentures, while the trueness of 3D printed dentures is not significantly better than that of traditional dentures.

PURPOSE: To investigate the expression of ubiquitin specific protease 20 (USP20) in oral squamous cell carcinoma (OSCC) and its correlation with clinicopathological parameters. METHODS: OSCC samples and paired paracancerous samples were screened from the TCGA database for differential expression analysis and paired differential analysis. Immunohistochemical staining was used to detect the expression level of USP20 in OSCC tissue, paracancerous tissues and normal tissues. The correlation between USP20 expression level and clinicopathological parameters of tissue microarray was analyzed. GraphPad Prism 9.5.0 software was used for statistical analysis of the data. RESULTS: TCGA data showed that the expression of USP20 in OSCC was significantly higher than that in paracancerous tissue(P＜0.001). Immunohistochemical staining score showed that the expression of USP20 in OSCC was significantly higher than that in paracancerous tissues and normal tissues(P＜0.01). The analysis of clinicopathological indicators of tissue microarray showed that the staining scores of USP20 were significantly different in tumor differentiation (P＜0.05) and primary tumor size (P＜0.01). Kaplan-Meier survival analysis indicated no significant difference in overall survival time and 5-year survival rate between high expression group and low expression group (P＞0.05). CONCLUSIONS: USP20 is highly expressed in OSCC compared with paracancerous tissues and normal oral tissues. The expression of USP20 is associated with differentiation and the size of primary tumor in OSCC，and can accelerate its growth.

PURPOSE: To evaluate the efficacy of micro-computed tomography(Micro-CT) in removing calcium hydroxide from posterior curved root canals. METHODS: Twenty molar teeth (48 root canals) extracted at the Department of General Dentistry, Shanghai Ninth People's Hospital between December 2023 and February 2024 were collected. After preparing by Ni-TI instruments M3 according to standard root canal treatment procedures, calcium hydroxide was injected into the root canals. One week later, the samples were randomly divided into 6 groups(n=8) based on different irrigation methods: sodium hypochlorite group, 17% EDTA group and 70% ethanol group. Each group was further divided into 2 subgroups with or without sonic vibration. Micro-CT was used to reconstruct the root canal system before and after irrigation, with independent root canals marked using different colors. The root canals were categorized as upper segment, middle segment, and apical segment. The volume of calcium hydroxide in each segment was calculated, and the clearance rate of calcium hydroxide in each segment was compared. SPSS 19.0 software package was used for statistical analysis. RESULTS: Calcium hydroxide could not be completely removed from any of the 6 groups tested. The removal efficiency of calcium hydroxide by ethanol in the apical region was higher than that achieved by other two groups(P＜0.05). In the ethanol subgroup, there was no significant difference in removal efficiency between sonic vibration and syringe techniques(P＞0.05). CONCLUSIONS: Using 70% ethanol enhances the removal efficiency of calcium hydroxide in curved root canal.

PURPOSE: This study was aimed to compare the difference between iRoot SP and AH Plus on root canal sealing ability for teeth extracted due to severe periodontitis and explore whether the dentin tubule pathway plays an important role in the development of endodontic-periodontic lesions(EPL), in order to provide a theoretical basis for selection of proper time for root canal therapy and suitable root canal sealants in patients with EPL. METHODS: Fifty single-root anterior teeth extracted due to severe periodontitis were selected. The roots were completely debrided to remove the calculus, dental plaque and cementum. They were divided into two groups, namely group A and group B, with 25 teeth in each group which included 21 experimental teeth and 4 negative control teeth. The root canals were filled with iRoot SP (group A) and AH Plus(group B) plus gutta-percha by cold lateral condensation technique. All roots were cut across the middle section and divided into coronal segment (group A1 and B1) of which the coronal section and apical section were sealed with self-etching adhesive and fluid resin, and then covered with melted casting wax twice. The apical segment of the experimental group was further divided into two subgroups, namely, the unsealed apical foramen group(group A2 and group B2) and sealed apical foramen group (group A3 and group B3). In group A2 and group B2, only the coronal section was sealed as mentioned above. While in group A3 and B3, both the coronal sections and apical foramen were sealed. The whole surface of the specimens in negative control group were all covered with melted casting wax twice. The samples were immersed in 1% methylene blue dye solution for 14 d, then they were longitudinally cut in half. Vernier caliper was used to measure the penetration length of the dye solution along the inner wall of each root canal. The sample sections were all photographed to process for Image Pro Plus software analysis of the penetration area of the dye solution in dentin tubule. The intra-group and inter-group differences were analyzed by one-way analysis of variance and LSD method, respectively. The data were analyzed by SPSS 26.0 software package. RESULTS: The penetration length of group A2 was significantly longer than that of group A3 (P＜0.05). The penetration length of group B2 was significantly longer than that of group B1 and B3 (P＜0.05). There was no significant difference between the corresponding subgroups of group A and group B (P＞0.05). Statistical analysis showed that the percentage of stained dentin tubule area in group A1 was significantly lower than that in group A2(P＜0.05), and the area percentage in group B1 was significantly lower than that in group B2 and B3(P＜0.05). There was no significant difference between the corresponding subgroups of group A and group B(P＞0.05). CONCLUSIONS: For periodontally compromised teeth, neither iRoot SP nor AH Plus paste combined with gutta-percha by cold lateral condensation technique could completely seal the root canal. There is no significant difference between iRoot SP and AH Plus paste on root canal sealing ability in teeth from periodontitis patients. Dentin tubules are not the main pathway of periodontal tissue and pulp communication. The pathway in the apical 1/2 segment of the root plays a more important role in the occurence of EPL, which suggest that root canal therapy may be taken into consideration when the clinical attachment loss reaches more than the apical 1/2 of the root.

PURPOSE: To analyze the effect of n-HA/chitosan/minocycline composite scaffold in the animal model of peri-implant inflammatory bone defect. METHODS: Twelve healthy adult male beagle dogs were selected to construct the model of peri-implant inflammatory bone defect. The control group(n=6) underwent bone regeneration by alveolar self-healing without any treatment in the bone defect area. In the experimental group(n=6), n-HA/chitosan/minocycline composite scaffold prepared was implanted into the bone defect site. Periodontitis, bone defect, pathological parameters, bone mineral density(BMD) and new bone formation rate were recorded in two groups of animal models. Statistical analysis was performed with SPSS 26.0 software package. RESULTS: There was no significant difference in the horizontal width and vertical depth of bone defect between the control group and the experimental group before treatment (P＞0.05). At 4, 8 and 12 weeks after treatment, the horizontal width and vertical depth of the experimental group were significantly lower than those before treatment and the control group(P＜0.05). There was no significant difference in probing depth(PD), sulcus bleeding index(SBI) and plaque index(PLI) between the control group and the experimental group before treatment(P＞0.05). PD, SBI and PLI in the experimental group were significantly higher than those before treatment and in the control group at 4, 8 and 12 weeks after treatment(P＜0.05). BMD value, new bone height and new bone formation rate of the experimental group were significantly higher than those of the control group at 4, 8 and 12 weeks after treatment(P＜0.05). CONCLUSIONS: n-HA/chitosan/minocycline composite scaffold shows a good effect in the model of peri-implant inflammatory bone defect, which can promote bone osteointegration and bone regeneration in the peri-implant bone defect area.

PURPOSE: To explore the effect of narrative medicine teaching practice on the narrative ability and empathy ability of dental interns and establish an effective narrative medicine teaching system. METHODS: From June 2022 to May 2023, atotal of 34 dental undergraduate students participating in clinical practice were divided into two groups, with 14 students in experimental group and 20 in control group. During clinical internships, the experimental group took narrative medicine into practice including theoretical lectures, close reading, parallel chart, seminars and so on. Interpersonal Reactivity Index(IRI) was used to evaluate the empathy of the students in the two groups, and a questionnaire survey was conducted on the narrative medicine practice of the experimental group. SPSS 12.0 software package was used for data analysis. RESULTS: The total score and module scores of empathy scale in the experimental group did not change significantly after the practice compared with before the practice. The score of "personal distress" module in the control group decreased significantly after the practice (P＜0.05), indicating that students in the control group who did not receive narrative education had a decrease in empathy after clinical practice. The questionnaire and parallel charts reflected that the interns' narrative ability and the understanding for medical psycho-social factors of experimental group students had been enhanced. CONCLUSIONS: Narrative medicine practice is helpful to improve narrative ability and empathy ability, cultivate professional quality and ease the doctor-patient relationship. It should be continuously promoted during the dental undergraduate teaching and dentist's practicing career.

PURPOSE: To exploring the clinical effect of lip muscle training combined with Frankel Ⅲ orthodontic appliances in correcting Class Ⅲ malocclusion during the mixed dentition period. METHODS: One hundred children with Class Ⅲ malocclusion during the mixed dentition period admitted to Hangzhou Greentown Stomatological Hospital from June 2018 to December 2022 were selected. The children were randomly divided into a combination group (treated with lip muscle training and Frankel Ⅲ orthodontic appliance) and a control group (treated with Frankel Ⅲ orthodontic appliance), with 50 cases in each group. X-ray cephalometric indicators, temporomandibular joint parameters, upper airway measurement parameters and 12 month follow-up of the two groups of children were compared before and after treatment. SPSS 21.0 software package was used for statistical analysis. RESULTS: Before treatment, there was no significant difference of SNA, SNB, ANB, U1-NA, L1-NB, ANS-Ptm, S-Ptm, Co Po, Co-S, MP-SN, MP-FH and NP-FH between the combination group and the control group (P＞0.05). After treatment, ANB, U1-NA, L1-NB and MP-SN in the combination group were significantly higher than those in the control group, while NP-FH were significantly lower than that in the control group(P＜0.05). Before treatment, there was no significant difference of the joint space, anterior joint space and posterior joint space between the combination group and the control group patients(P＞0.05); after treatment, the joint space and the joint space in the combination group were significantly higher than those in the control group(P＜0.05). Before treatment, there was no significant difference of Ba PNS, Ad1 PNS, Ad2 PNS, Mc1 Mc2, SPP-SPPW, U-MPW, PAS and V-LPW between the combination group and the control group(P＞0.05); after treatment, Ad2-PNS in the combination group was significantly higher than that in the control group(P＜0.05). After 12 months of follow-up, the recurrence rate of the combination group was 2.00%, which was significantly lower than that (16.00%) of the control group (P＜0.05). CONCLUSIONS: The combination of lip muscle training and Frankel III orthodontic appliances is more conducive to correcting Class III malocclusion during the replacement period, improving upper airway morphology, and reducing the recurrence rate after treatment.

PURPOSE: To evaluate the effect of bone nail and artificial periosteum combined with iliac cancellous bone grafting in repairing cleft lip and palate with alveolar cleft during dental replacement. METHODS: The clinical data of 82 children with cleft lip and palate with alveolar cleft during dental replacement period were retrospectively analyzed from January 2020 to December 2023, and were divided into control group (iliac cancellous bone grafting alone, n=42) and experimental group (combined iliac cancellous bone grafting with bone nail and artificial periosteum, n=40) according to the operation method. The viable bone volume in bone graft area, absorption rate of whole bone graft and different bone graft areas, success rate of bone graft, survival rate of bone graft and complications were compared between the two groups. SPSS 25.0 software package was used for statistical analysis. RESULTS: The surviving bone volume in the bone graft area was significantly larger in the experimental group 3 and 9 months after operation(P＜0.05). There was no significant difference in viable bone volume in bone graft area between the two groups 9 months and 3 months after surgery (P＞0.05). The bone graft absorptivity of the experimental group was significantly lower than that of the control group 3, 9 months and 3-9 months after surgery(P＜0.05), and there was no significant difference between the two groups at 3, 9 months after surgery(P＞0.05). The absorption rate of bone graft in 1/2 area of nasal cavity, 1/2 area of alveolar ridge, 1/2 area of lip and 1/2 area of palate in the experimental group was significantly lower than that in the control group 3 and 9 months after operation(P＜0.05). The absorptivity of bone graft in 1/2 area of alveolar ridge was significantly higher than that in 1/2 area of nasal cavity, and the absorptivity of bone graft in 1/2 area of palatal side was significantly higher than that in 1/2 area of lip in both groups (P＜0.05). The success rate and survival rate of bone grafting in the experimental group were significantly higher than those in the control group(P＜0.05). The complication rate of the experimental group was significantly lower than that of the control group (P＜0.05). CONCLUSIONS: Bone nail and artificial periosteum combined with iliac cancellous bone graft can effectively repair cleft lip and palate with alveolar cleft during dental replacement, reduce bone absorption rate and complications, and improve bone formation effect. Meanwhile, postoperative bone mass absorption mainly occurs within 3 months after surgery, and mainly occurs in the alveolar crest area and palatine area.

PURPOSE: To investigate the effect of dual-wavelength laser combined with bioceramics material iRoot SP on molar root canal treatment. METHODS: A total of 104 patients receiving root canal treatment from January 2020 to June 2023 were selected and divided into control group and experimental group according to random number table method, with 52 cases in each group. The control group was treated with iRoot SP paste, and the experimental group was treated with dual-wavelength laser(Nd:YAG and Er:YAG) combined with iRoot SP paste. The total effective rate, pain degree and complications were compared. Serum interleukin-6 (IL-6), interleukin-17(IL-17), tumor necrosis factor-α(TNF-α), bleeding index(BI), depth of periodontal probing(PD) and clinical attachment level(CAL) were observed before treatment, 6 weeks and 12 weeks after treatment. SPSS 22.0 software package was used for statistical analysis. RESULTS: The total effective rate of the experimental group was significantly higher than that of the control group, and the pain degree after root canal filling was significantly lower than the control group(P＜0.05). The levels of IL-6, IL-17, TNF-α, BI, PD and CAL in the experimental group were significantly lower than those in the control group at 6 and 12 weeks after treatment (P＜0.05). CONCLUSIONS: Dual wavelength laser combined with bioceramic material iRoot SP has a better effect in the treatment of molar root canal, which is conducive to reducing periodontal inflammation and pain.

PURPOSE: To determine the latent class and heterogeneous associations of oral health behaviors (OHB) with caries in preschool children aged 3-6 years, and to develop effective oral health interventions for improving their health status. METHODS: Latent class analysis(LCA) was applied to classify eight OHBs in three dimensions: oral hygiene, dietary habits, and preventive protection in 595 preschool children. Optimal classes were determined using model fitting and explanatory metrics, and marginal effects were estimated using bivariate association and multivariate regression models. The correlation between OHBs and caries was explored using Chi-square and correspondence analysis with SPSS 27.0 software package. RESULTS: Among 595 preschool children, caries prevalence was 54%, and OHBs were classified into two latent classes: favorable (88%) and unfavorable (12%). Unfavorable OHBs were associated with higher caries prevalence (58% vs. 52%), poorer caries status (mean dmft: 3.52 vs. 2.44), and lower regular examination experience (63% vs. 66%) compared to favorable OHBs. The difference in caries severity distribution between the two classes was statistically significant (P＜0.05). CONCLUSIONS: Oral health behaviors in preschool children are heterogeneous and associated with caries. Effective interventions for improving OHBs in preschool children should be tailored according to this heterogeneity.

PURPOSE: To analyze the correlation between the changes in salivary ion concentration, Streptococcus and Bifidobacterium in children with dental caries and the severity of the disease. METHODS: Eighty children with dental caries treated from May 2022 to April 2023 were selected as the experimental group. According to the DMFT, they were divided into mild group (DMFT≤15%, n=35) and severe group (DMFT>15%, n=45). Another 80 children without dental caries were selected as the control group. The calcium ion concentration in saliva was detected by methanol-permeabilized calciometric method, the level of Streptococcus and Bifidobacterium was detected by real-time single-quantity PCR technology, and the correlation between DMFT and salivary calcium ion concentration, Streptococcus and Bifidobacterium was analyzed by Pearson correlation analysis. The diagnostic value of salivary calcium ion concentration, Streptococcus and Bifidobacterium for the severity of dental caries in children was evaluated by the receiver operating characteristic curve(ROC), and the area under the curve(AUC) was calculated. SPSS 22.0 software package was used for statistical analysis. RESULTS: The level of salivary calcium ion concentration, Streptococcus mutans, Streptococcus sobrinus and Bifidobacterium in the experimental group was significantly higher than that in the control group(P＜0.05), and significantly higher in the severe group than in the mild group(P＜0.05). DMFT was significantly positively correlated with salivary calcium ion concentration, Streptococcus and Bifidobacterium (P＜0.05). Based on DMFT, ROC curve was prepared, and AUCs of salivary calcium ion concentration, Streptococcus mutans, Streptococcus sobrinus and Bifidobacterium for assessing the severity of dental caries in children were 0.760, 0.658, 0.718 and 0.705, respectively. CONCLUSIONS: Increased salivary ion concentration, Streptococcus sobrinus, Streptococcus mutans and Bifidobacterium levels are related to dental caries in children, and are positively correlated with the severity of the disease, which has a certain value for assessing the severity of the disease.

PURPOSE: To analyze the effects of fixed appliance and invisible appliance without bracket on anterior tooth root and alveolar bone in patients with mild to moderate overcrowding of Class Ⅰmalocclusion. METHODS: A total of 120 patients with mild to moderate dental crowding were selected from January 2018 to February 2022,and divided into control group and experimental group by random number table method, with 60 cases in each group. The control group was treated with traditional fixed appliance, while the experimental group was treated with invisible appliance without bracket. Cone-beam CT(CBCT) was taken before and 12 months after treatment to measure the root length and alveolar bone height and thickness of maxillary central incisor teeth, height of alveolar bone of anterior teeth lip and lingual side and cusp teeth in both groups. Statistical analysis was performed with SPSS 22.0 software package. RESULTS: The root length changes of maxillary central incisor, lateral incisor and cusp teeth in the experimental group were significantly lower than those in the control group before and after treatment(P＜0.05). The alveolar bone height changes in the labial side and lingual palatine side of upper anterior teeth, labial side and lingual palatine side of inferior anterior teeth in the experimental group before and after treatment were significantly lower than those in the control group(P＜0.05). The thickness changes of labiolingual alveolar bone at the neck, middle root and apex of upper and inferior anterior teeth in the experimental group were significantly lower than those in the control group before and after treatment(P＜0.05). CONCLUSIONS: Compared with fixed appliance, invisible appliance without bracket can reduce root resorption and the loss of alveolar bone height and thickness in the treatment of Class I patients with mild to moderate dental crowding.
