BACKGROUND: Bonded retainers are widely used to maintain the positions of anterior teeth after orthodontic treatment. Various types of bonded retainer exist however, there is a lack of evidence to indicate which type is superior. AIM: To compare upper and lower CAD/CAM nitinol bonded retainers (Memotain) with upper and lower chairside rectangular-chain bonded retainers (Ortho-FlexTech™), in terms of stability, retainer failures and patient satisfaction. TRIAL DESIGN: Multi-centre, two-arm, parallel-group, randomised controlled clinical trial with 1:1 allocation. SETTING: Three trial centres: University Teaching Hospital; District General Hospital; and Specialist Orthodontic Practice. All treatment was provided free as part of a state-funded healthcare system. MATERIALS AND METHODS: A total of 68 patients were randomly allocated to receive either upper and lower Memotain bonded retainers or upper and lower Ortho-FlexTech™ bonded retainers. Ten trained operators placed and reviewed the bonded retainers. Measurements were carried out on study models taken at debond and after six months. Patient satisfaction questionnaires were completed at six months following debond. RESULTS: The trial was terminated due to the high number of failures (50%) of the upper Memotain® retainers within six months. Memotain retainers were three times more likely to fail (unadjusted hazard ratio = 2.82, 95% confidence interval = 1.00-7.99) than Ortho-FlexTech™ retainers at six months in the upper arch. Patients were satisfied with both types of retainer. LIMITATIONS: Early termination of the trial means that the a priori sample size was not reached, so outcomes should be interpreted with caution. CONCLUSION: The trial was terminated early due to the high failure rate of upper Memotain bonded retainers. They had a higher risk of failure in the maxillary arch when compared to upper Ortho-FlexTech™ bonded retainers after six months.

OBJECTIVE: To evaluate the relevant scientific literature to determine the association between different serum biomarker levels and radiographic skeletal maturity indicators. DATA SEARCH, SCREENING AND ELIGIBILITY: A literature search was carried out on PubMed, Cochrane Library, Google Scholar, Semantic Scholar, Science Direct and Opengrey.eu up to November 2021 and 7466 records were retrieved via the electronic search. Study selection, data extraction and subsequent risk of bias assessment (RoB) was carried out independently by two authors. In case of any discrepancy, a third author was consulted. RESULTS: After the exclusion of duplicates and the application of inclusion exclusion criteria, 19 studies (published in 25 articles) were included in the systematic review out of which 17 had a cross-sectional and two had a cohort study design. For the meta-analysis, based on the homogeneity, five cross-sectional studies measuring serum IGF-1 levels were incorporated. The meta-analysis revealed that the serum IGF-1 levels peak at the CS4 stage (401.77 ng/mL [333.50 - 470.05]) in the pooled group. However, in the subgroup analysis, it was found that the serum IGF-1 levels peak at CS3 in girls (422.82 ng/mL [377.46-468.18]) and CS4 in boys (487.04 ng/mL [391.83-582.25]). CONCLUSION: Among the various biomarkers evaluated, serum IGF-1 was the most associated with different stages of radiographic skeletal maturity indicators with its levels peaking at CS3 in girls and CS4 in boys.

OBJECTIVE: To evaluate whether delaying treatment with a twin block appliance affects treatment outcomes, in terms of skeletal and dental change and psychological disadvantage. DESIGN: Multicentre, two-arm parallel randomised controlled trial. SETTING: Three UK hospital orthodontic units. METHODS: A total of 75 participants were randomly allocated into an Immediate Treatment Group (ITG) (n= 41) and an 18-month delayed Later Treatment Group (LTG) (n=34). OUTCOMES: Dentofacial changes were recorded from lateral cephalograms and study models, psychological impact was measured using a child perception questionnaire (CPQ11-14) and an Oral Aesthetic Subjective Impact Score (OASIS) at registration (DC1), 18 months (DC2) and 3 years (DC3). RESULTS: The ITG initial effect was a mean ANB reduction was 1.6° (<0.001) (95% confidence interval [CI] = 0.89-2.29), and an overjet reduction of 5.06 mm (<0.001) (95% CI = 3.96-6.16) (boys: aged 12 years 8 months; girls: aged 11 years 8 months). There were no statistically significant differences between the ITG and LTG for twin block treatment outcomes, but the ITG active treatment time was longer (=0.004) (ITG: 13.1 months; LTG: 9.8 months). There was insufficient evidence to state that patients were psychologically disadvantaged by waiting 18 months for active twin block treatment (>0.05). CONCLUSION: Participants achieved similar clinical and psychological outcomes irrespective of whether they started their twin block at the age of referral (ITG) or 18 months later (LTG). This suggests that boys aged 12 years 8 months and girls aged 11 years 8 months, on average, are not disadvantaged by waiting 18 months for active twin block treatment.

OBJECTIVE: To assess the effectiveness of the Royal London Space Planning (RLSP) as a learning tool among postgraduate orthodontic students as well as investigate students' attitudes to its use. The RLSP tool is a structured method of orthodontic case assessment and treatment planning. DESIGN: A prospective cohort study of first year postgraduate orthodontic students who attended teaching of the RLSP. SETTING: Postgraduate teaching institute. PARTICIPANTS: First year postgraduate orthodontic students. METHODS: The outcome measured was the accuracy in assessment and planning of a standardised orthodontic simulated case before and after teaching. Qualitative assessment was conducted through focus group and a semi-structured format after the teaching. RESULTS: Nineteen students were included in the study. There was an overall improvement in assessment and planning of 20% after the teaching intervention ( < 0.05). Assessment improved by 34% in comparison to treatment planning, which improved by 17% ( < 0.05). The impact of the RLSP was most noticeable on the assessment of crowding in the lower arch which improved by 37% after teaching ( < 0.05). Students felt using the RLSP tool made them more confident and was advantageous to use in training; most felt they would not use the tool after qualification. CONCLUSION: The RLSP tool is an effective method of teaching assessment and treatment planning to postgraduate orthodontic students. The effect of the RLSP is greater at assessments and less significant for treatment planning. The participant students felt the RLSP improved their confidence in assessment and treatment planning.

OBJECTIVE: To apply an automated computerised method to categorise and determine the prevalence of different types of lip traits, and to explore associations between lip traits and sex differences. DESIGN: Observational descriptive study utilising an automated method of facial assessment. SETTING AND PARTICIPANTS: A total of 4747 children from the Avon Longitudinal Study of Parents and Children (ALSPAC) who each had 3D facial scans carried out at 15 years of age. METHODS: Each of the participants was automatically categorised regarding predetermined lip morphological traits. Descriptive statistics were applied to report the prevalence of the different types of each trait, and chi-square tests were used to investigate sex differences and associations between traits. RESULTS: A total of 4730 individuals were assessed (47% male, 53% female). Eight predetermined lip traits have been reported previously. There were differences in prevalence for all lip traits in male and female patients (all ⩽ 0.0002), with differences between the sexes described for each trait. For example, a deeply grooved philtrum of average width was more prevalent in boys, and an indentation near the upper vermilion border was more prevalent in girls. Each of the traits was significantly associated with the other traits (all < 0.0001), with particularly strong associations seen between traits in the same region (e.g. upper lip). Individual associations between traits are reported; for example, a straight lip contour was found to be associated with no true vermilion border in both the upper and lower lip regions. CONCLUSION: The automated computerised method described is an invaluable tool for the categorisation of lip morphological traits. The prevalence of various types of traits has been described. Sexual dimorphism exists for all the lip traits assessed. Generally, each of the traits are associated with all other traits, with individual associations reported.

OBJECTIVE: To determine the quality of online information regarding ectopic and impacted maxillary canines (EIMCs). DESIGN: A cross-sectional survey on the Internet. MATERIAL AND METHODS: An online search using eight terms was carried out using four search engines. The relevant content of websites satisfying the inclusion and exclusion criteria were assessed for quality by applying three quality of information instruments and one readability tool. Statistical analyses were performed through GraphPad Prism 9.0. RESULTS: In total, 77 websites were evaluated. Most of the assessed content was associated with oral and maxillofacial surgery (49.35%) and orthodontic websites (31.18%). The overall mean DISCERN score was 38.05 ± 9.76/80 with 59.73% of websites recording a poor or very poor score. Three (3.9%) websites contained the HONCode seal. Twelve (15.58%) websites satisfied at least three out of a maximum four benchmarks and 11 (14.29%) satisfied none. The mean SMOG score was 9.81 ± 1.52 (95% confidence interval = 9.46-10.16; range = 6.7-15.1). CONCLUSION: The quality of online information related to EIMCs was poor and the content was difficult to read. Professional societies and clinicians should consider the use of quality of information and readability tools to enable the provision for reliable, high-quality and readable online information. This will assist EIMC treatment-related decision-making and management by patients and their families.

OBJECTIVE: To determine whether maternal smoking and/or alcohol consumption has an influence on lip morphology. Maternal smoking is a known risk factor for orofacial clefts; however, its influence on normal lip variation is unknown. Recent research regarding normal lip morphology has been contradictory. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: A total of 4747 children from the Avon Longitudinal Study of Parents and Children (ALSPAC) who each had 3D facial scans carried out at 15 years of age were included in the study. METHODS: Each of the participants was automatically categorised regarding predetermined lip morphological traits. Questionnaires completed by their mothers identified smoking and alcohol habits during pregnancy. Logistic regression analyses were applied to determine the effect of maternal smoking and alcohol consumption on lip morphology. RESULTS: Maternal smoking has significant effects on upper and lower lip contours, Cupid's bow, lower lip-chin shape and lower lip tone (all < 0.05). There was also an indication of a potential epigenetic effect of smoking pre-pregnancy on upper lip contour ( = 0.0573). Alcohol consumption is significantly associated with philtrum shape, particularly when >6 units of alcohol are consumed per week ( = 0.0149, 32 weeks). Overall results suggest a deeply grooved philtrum is more likely if alcohol is consumed. Investigating the combined effect of smoking and alcohol consumption, lower lip contour ( = 0.00923) and lower lip-chin shape ( = 0.0171) are statistically significant, with lower lip contour more likely to be narrow in the midline, and lower lip-chin shape more likely to be an angular concavity. CONCLUSION: Maternal smoking influences a number of lip traits, including a possible epigenetic effect on upper lip contour. Maternal alcohol consumption, particularly at a high level, influences philtrum shape. Maternal smoking and alcohol consumption have a combined effect on lower lip contour and lower lip-chin shape.

OBJECTIVES: To assess the knowledge, practice and challenges faced by general dental practitioners (GDPs), paediatric dentists (PDs) and postgraduate paediatric dentistry students (PGPDSs) in diagnosing and managing early orthodontic problems. DESIGN: Cross-sectional study. METHODS: A total of 159 dentists were enrolled in this study (121 GDPs, 21 PDs and 17 PGPDSs). Data were collected using a self-administered questionnaire involving two sections. Section A included questions regarding demographic features and orthodontic practice. Section B included photos of 12 orthodontic cases that needed early intervention. Knowledge and practice were assessed using six questions for each case that was then rated using predefined scores of poor (score <50%), average (score 50%-75%) and good (score >75%). RESULTS: The knowledge scores regarding the identification of early orthodontic problems were average among the three groups with GDPs having the lowest score ( = 0.0001). The knowledge scores regarding the selection of optimal treatment time were average among the PDs and PGPDSs, and poor among GDPs. GDPs tended to refer most of their cases to an orthodontist except for cases of thumb sucking. PDs and PGPDSs were more confident in treating anterior crossbite, thumb sucking habits and delayed eruption of incisors. All participants scored 'poor' regarding the selection of an appropriate orthodontic appliance. There was no significant correlation between knowledge and practice ( > 0.05). CONCLUSION: PDs and PGPDSs showed higher knowledge and practice scores when compared to GDPs. For all three groups included in this study, lack of clinical skills was the main reason for not treating early orthodontic problems.

INTRODUCTION: Across the United Kingdom (UK), National Health Service (NHS) orthodontic treatment is commissioned differently across the devolved nations. There is a relative paucity in the literature describing the way in which the orthodontic services in each country are commissioned and treatment outcomes measured. OBJECTIVE: To highlight the differences in the following: commissioning of primary care orthodontic services across the UK; assessment of treatment outcomes; and the potential impacts these differences have on contractors, performers and patient care. MATERIALS AND METHODS: Data were collected using an online mixed-methods approach. Systematic content analysis was used to extract the required information from the websites and guidance documents of orthodontic service providers, which was then catalogued and verified electronically by senior dental advisors in the four devolved UK nations. RESULTS: The Index of Orthodontic Treatment Need (IOTN) is a mandatory needs assessment tool used across all four nations, with an agreed minimum threshold of a dental health component (DHC) score of 3 and an aesthetic component (AC) score of 6 for NHS treatment. While the peer assessment rating (PAR) is the most utilised method of assessing post-treatment outcomes, it is applied differently by each country. CONCLUSION: While NHS orthodontic services across the UK share mutual elements of service delivery, there are significant differences in the prior approval process and assessment of treatment outcomes. More research is required to assess the economic feasibility of orthodontic treatment from the associated treatment outcomes.

OBJECTIVE: To investigate young people's experiences of retainers, the associated impact of retainers on their lives and their perceptions of what influences their own co-operation. DESIGN: Qualitative, cross-sectional study. SETTING: An orthodontic department in a UK dental hospital. PARTICIPANTS: Purposive sampling was used to recruit young people, aged 11-17 years, wearing a range of different types of retainers. METHODS: Semi-structured interviews were conducted and transcribed. The resultant data were analysed using codebook thematic analysis. RESULTS: Ten patients were recruited before thematic saturation was achieved. Four themes were identified: impact and experiences of wearing retainers; facilitators and barriers to retainer adherence; finding out about retainers; and, finally, involvement in decisions about retainers. Although some initial negative impacts were described, participants generally adapted quickly to retainers. Several factors were perceived to influence co-operation with removable retainers, including concerns about relapse and the associated waste of personal effort and wider resources. There were perceived deficiencies in the information provided by clinicians, which led participants to seek advice from other sources, including social media. Some young people wanted to be more involved in decisions about their retainers. CONCLUSION: While patients perceived retainers to be easier to wear than active appliances, some transient negative impacts occurred, largely related to initial periods of full-time wear. There were a range of factors which patients perceived to influence their adherence with removable retainers.

OBJECTIVE: To assess the effects of mini-implant assisted micro-osteoperforations (MI-MOPs) in the alignment of mandibular anterior teeth, and to explore the intervention's associated pain perception (PP) and root resorption (RR) in adults treated by fixed appliance. DESIGN: Multicentre, two-arm and single-blinded randomised clinical trial. SETTING: College of Dentistry, University of Baghdad. PARTICIPANTS: Adolescents (mean age = 18.97 years) undergoing non-extraction orthodontic therapy for the management of mandibular anterior crowding. METHODS: A total of 33 participants (mean age = 18.97 years) undergoing non-extraction orthodontic therapy for the management of moderate mandibular anterior crowding were allocated to the experimental (MI-MOPs, n = 17) or control groups (non-MI-MOPs, n = 16). A series of lower study models were obtained at week 4 (T1), week 8 (T2) and week 12 (T3) in the MI-MOPs group and continued to week 16 (T4) and week 20 (T5) in the non-MI-MOPs group, with all models analysed digitally. Periapical radiographs (PA) were taken before commencing treatment (T0) and T3. Participants were asked to complete a 10-point visual analogue scale (VAS) daily during the first week of treatment. RESULTS: At T0, the mean Little irregularity index (LII) was 5.1 mm (95% confidence interval [CI] = 4.95-5.23) with no statistically significant difference between groups ( = 0.766). At T1, T2 and T3, t-test showed statistically significant differences in the LII ( < 0.05) in favour of the MI-MOPs group; mean differences (MD) were -1.16mm (95% CI = -1.36 to -0.96), -1.77 mm (95% CI = -1.93 to -1.59) and -1.58 mm (95% CI = -1.67 to -1.48), respectively. Mean treatment time from baseline to final alignment was 10.41 weeks (95% CI = 9.92-10.89) in the MI-MOPs group and 16.62 weeks (95% CI = 16.11-17.13) in the non-MI-MOPs groups, which was statistically significant (MD -6.21 mm, 95% CI = -6.88 to -5.53, < 0.05). Conversely, Mann-Whitney -test and Wilcoxon signed-rank test showed no significant differences in terms of PP and RR between the groups ( > 0.05). The participants in the MI-MOPs group experienced a higher degree of RR ( < 0.05) secondary to intervention. No other significant adverse events were reported during the trial. CONCLUSION: This trial found that combining MI-MOPs with non-extraction-based fixed orthodontic therapy in adults mildly shortens the duration of the alignment phase. RR should be monitored throughout the treatment when using MI-MOPs (ClinicalTrials.gov NCT04778241).

OBJECTIVE: To assess the impact of nasal deviation on the perception of the maxillary dental centreline position as judged by orthodontists, dentists and laypersons. DESIGN: Cross-sectional study. SETTING: Barts and the London School of Medicine and Dentistry, Queen Mary University of London, UK. PARTICIPANTS: Three groups of raters comprising 30 orthodontists, 30 dentists and 30 laypersons. METHODS: A frontal photograph of a smiling white woman was captured and digitally manipulated with varying degrees of nasal deviation and dental centreline (DC) position in increments of 1.5 mm and 3 mm to the right and left. Three rater groups assessed the attractiveness of images using a visual analogue scale (VAS). Multiple regression analysis was undertaken, and images were compared using the Tukey HSD method. RESULTS: Using a mixed linear model, the intraclass correlation coefficient (ICC) was estimated in the range of 69%-86%, indicating good inter-rater reliability. The interaction between image rating and nasal position ( < 0.001), DC position ( < 0.001) and the relationship between nose and DC position ( < 0.001) were found to be statistically significant with symmetrical upper midline and nasal tip position, both considered to be most aesthetically pleasing. Image rating was not influenced by rater group type ( = 0.995), age ( = 0.983) or sex ( = 0.476). CONCLUSION: There was a preference for a central and coincident nose and maxillary DC position uniformly across the rater groups. Deviations of the nose, DC and their interactions negatively impacted on perceived smile aesthetics with increasing extent and opposing direction of deviations rated progressively more unaesthetic. No differences were observed between orthodontists, general dental practitioners and lay people with respect to perceived impact on smile aesthetics.

OBJECTIVE: To assess the awareness and usage of mobile apps and social media among orthodontic clinicians to support patients with orthodontic treatment, support the professional development of orthodontists, and identify any relevant apps and social media platforms currently recommended to patients. DESIGN: Cross-sectional questionnaire-based study. SETTING: United Kingdom. METHODS: A questionnaire was developed and distributed to members of the British Orthodontic Society (BOS). To increase the response rate, the questionnaire was circulated at three time points between January and March 2020. RESULTS: A total of 149 orthodontists responded to the questionnaire (15% response rate) with 113 orthodontists completing all questions (11.4%). Of those who answered, 81% (n = 111) had been qualified for >10 years, 35% worked in practice (n = 48), 34% worked in a hospital (n = 47) and 26% worked in both hospital and practice (n = 36). The results indicated that 20% of clinicians (n = 22) used apps to support patients and 33% (n = 37) reported using apps for professional purposes. Brush DJ appeared to be the most popular patient focused app (39%, n = 18) whereas the IOTN (17%, n = 8), Invisalign (17%, n = 8) and Dental Monitoring apps (9%, n = 4) were the most popular clinician-focused apps. With regard to social media, 53% (n = 60) of respondents reported that they used social media to communicate generic orthodontic information and promote their practice to patients. The most commonly used social media platforms were Facebook and Instagram. Of respondents, 96% expressed a willingness to recommend an evidence-based mobile app to patients if available, and 88% were willing to recommend an evidence-based social media platform. CONCLUSIONS: Orthodontic clinicians are utilising mobile apps and social media to support both patients and their own professional development. There is a willingness to increase the use of evidence-based platforms and apps to support patients.

OBJECTIVE: To find the effect of extraction of the lower first permanent molar in children (aged 8-11 years) on the position and angle of the developing third molar. DESIGN: Retrospective radiographic analysis. PARTICIPANTS: Two cohorts of participants were identified: an extraction group, who had extraction of one or more first permanent molars aged 8-11 years; and a non-extraction group, who retained all mandibular teeth. Both cohorts previously had panoramic radiographs taken at mean ages of 9.7 years (T1), before extraction, and 12.12 years (T2). In total, there were 61 third molars with an associated extracted first permanent molar and 60 third molars with an associated retained first permanent molar. METHODS: A digital radiographic analysis was carried out on the panoramic radiographs to measure the movement of the third molar, vertically and horizontally, and its angle. The magnification of the T1 and T2 radiographs was calibrated. Reliability of the radiographic analysis was confirmed via intra- and inter-rater reliability tests. The extraction and non-extraction groups were compared via independent sample tests. RESULTS: The third molar moved significantly more mesial in the extraction group ( < 0.001) and the angle uprighted significantly more than the non-extraction group ( < 0.001). Vertically, the third molar moved inferiorly in both cohorts with no significant difference. CONCLUSION: In the developing dentition, extraction of the lower first permanent molar encouraged mesial movement and uprighting of the developing third molar. This may improve the likelihood of future eruption of the third molar.
