OBJECTIVES: To determine the frequency of expression and sexual dimorphism of the following dental morphological traits on the permanent mandibular first molar (LM1) in the living Jordanians: Entoconulid (cusp 6; tuberculum sextum), metaconulid (cusp 7, tuberculum intermedium), post-metaconulid and pre-entoconulid (entostylid) traits. In addition, to analyze inter-trait interactions whenever possible was one of the aims. METHODS: Three hundred sixty school children (176 males, 184 females, ages 15.5 +/- 0.4 years) from the middle of Jordan were involved. Impressions for the mandibular dental arches were taken, and dental casts were produced in 2009. The above-mentioned traits were observed. Z-value test between two proportions and nonparametric correlation analysis were used for data analysis. RESULTS: Cusp 7 on LM1 was found in 15.83 %, while cusp 6 on this tooth was found in 21.67% of the examined students. In comparison, both post-metaconulid and pre-entoconulid traits were found to be absent on LM1 in all observed subjects. Nonparametric correlation analysis revealed weak negative and statistically insignificant association between the expression of cusp 6 and 7 on LM1 among the living Jordanians. CONCLUSION: Both cusp 6 and cusp 7 on LM1 are expressed in a relatively higher rate among the living Jordanian Arabs than other studied Western Eurasians, suggesting a significant gene flow from Sub-Saharan Africans and Mongolians to the Middle East. In addition, the insignificant weak correlation between cusp 6 and 7 on LM1 suggests that these two dental morphological traits are both genetically and phenotypically independent.

The term anterior open bite refers to a vertical space between the upper and lower front teeth in maximum intercuspation. This malocclusal trait can accompany many malocclusions of the Angle's classification. Two types of anterior open bite have been described: skeletal and dental open bite. The latter may have Non Nutritive Sucking Habits (NNSH) as causal factor and is deemed to aggravate without treatment. This article presents an interceptive approach based on the use of a fixed passive appliance interfering with sucking habit. It consists of a crib soldered to bands adjusted to the maxillary first permanent or temporary second molars. The device was globally well accepted by the patient and has been effective in breaking the sucking habit and subsequently in closing the bite after only 5 month. When psychological approach is not effective, a fixed deterrent device may be recommended for weaning children off nonnutritive sucking habits.

OBJECTIVES: This study describes early childhood caries prevalence and caries risk in a group of Lebanese preschoolers. METHOD AND MATERIALS: 99 healthy children, aged four years or less, were recruited at the Dental medicine faculty, Saint-Joseph university, Beirut, Lebanon. After parental consent, questionnaires investigated children's dietary and oral hygiene habits and parents' education and health behaviors. Oral examinations, with bite-wing radiographs when necessary, determined decayed-filled surfaces and plaque scores. Salivary testing assessed buffer capacity and streptococcus mutans (Sm) and lactobacillus (Lb) presence. The three tests (questionnaire, oral examination, salivary testing) established a caries risk assessment tool, determining subjects' caries risk scores, classified as low (C0), moderate (C1), high (C2) or very high (C3). RESULTS: 25.3% of subjects were caries-free, 24.2% had 4 carious lesions or less, 28.3%, 5 to 9 lesions and 22.2% over 10 lesions. 11.1% of plaque scores were low to mild, 18.2% moderate, 46.4% high, and 24.3% very high. Salivary buffer capacity was: 29.3% high, 57.6% medium and 13.1% low. High levels of Sm, (66.7%) correlated with plaque presence and proximal caries. High levels of Lb (52.5%) correlated with plaque presence and smooth-surface caries, and correlated significantly with occlusal caries. Regular tooth brushing yielded lower plaque, but not significantly lower caries levels. Systemic fluorides were associated with lower plaque and caries scores. Children of educated parents with regular dental visits and oral hygiene had lower plaque and caries scores. Caries risk distribution was: CO: 16.2%, C1: 29.3%, C2: 15.1% and C3: 39.4%. CONCLUSION: Most subjects had at least one carious lesion (74.7%), and 70.7% showed high to very high plaque scores. Over half the sample presented high or very high caries risk. These findings deserve further investigation of the Lebanese preschoolers' population.

CONTEXT: The survey appears in the setting of the politics of improvement for prevention of professional risks in hospital environment in Ivory Coast. PURPOSE: To identify the influence factors of the coif of rotators pathology among dentist surgeons and to improve the preventive measures. TYPE OF STUDY: It was a prospective case/witness survey type. It had for setting, public hospitals and private clinics in Abidjan. METHODOLOGY: We enrolled two types of population (case/witness) comparable with the criteria's of age, sex, bodily mass indication (BMI) and laterality. The data have been collected on a standardized questionnaire named "Nordic questionnaire" and have been enriched. That informed on the bodily mass indication calculated according to the method: weight/T2 (m), on the epidemiological data and the specifics data of the shoulder and the coif of the rotators. The statistical tests have been done by the test of the Khi2 of Pearson, the test of T Student, the exact test of Fischer and the test of the gap reduces. RESULTS: The study included 100 cases and as many witnesses. The middle age of apparition of the tendinitis of the shoulder was of 38,83 years. Age, sex, bodily mass and professional experience didn't have any influence on the apparition of the lesion of the shoulder. The analysis of the results established that the professional seniority encourages the apparition of the lesion of the shoulder. The length on average some seniority is of 12,7 years with extremes of 2 and 30 years. This observation rests on the fact that the risks of intervening of musculo-skeletal unrests of the superior member is equal to the length of work (effort, repetitive acts and stance) returned to the functional capacities. CONCLUSION: The tendinitis of the shoulder, because of its importance must be recognized and repaired as an indemnisable professional disease.

OBJECTIVE: To determine the prevalence of malocclusion in adolescents with special needs and to compare the results with those of other authors. METHODS: The study sample consisted of 230 adolescents with special needs aged 12-17 years randomly selected from 5 special school/centres in Lagos. Occlusal anteroposterior relationships were assessed based on Angle classification. RESULTS: Normal occlusion was seen in 11.7%, Angle's class I malocclusion in 77.4%, class II malocclusion in 8.3% and class III malocclusion in 2.6%. Over 63% had normal overbites, and 6.5% and 12.5% had increased and reduced values, respectively. Overjet relationship was normal in 50%, increased in 25.7% and reduced in 6.5%. Crowding was observed in 29% of the subjects and midline diastema in 27%. Males had a significantly higher prevalence of midline diastema than females (p < 0.05). The intellectually impaired had significantly higher frequency of class II division 1 malocclusion and anterior openbite when compared with the other disabled groups. CONCLUSION: Class I malocclusion is the most prevalent occlusal pattern among adolescents with special needs. Statistically significant differences in occlusal pattern were observed between the disabled groups.

Coronal-radicular restoration is the coronal reconstruction of an endodontically treated tooth, with a support on and in the root. The objective of this study is to assess the importance of the carried coronal-radicular restorations in the dental practice in Abidjan. It is about a prospective survey of 100 dental surgeons practicing in the city of Abidjan, pulled at random. The information was collected through a self-interview. As results, 79% of our population knows and performs coronal-radicular restorations especially in the absence of 3 dental walls but at a very low, less of 5/month for 90% of this population. The protocol of realization seems well known and followed for the majority of the pooled practitioners. However, we deplored often absence of radiography in the protocol and also the exclusive use of metal posts. In conclusion, the coronal-radicular restorations are much used in the daily practice in Côte d'Ivoire. The protocol for achieving this type of restoration seems well known and followed by the practitioners according to our study. However, as material all the dentists are still in the screw post (metal post). The adhesive technologies using fiber posts don't seem accessible to our people.

OBJECTIVE: To determine the frequency, causes and pattern of tooth extraction in a Nigerian rural health facility. MATERIALS AND METHOD: This descriptive cross sectional study was conducted in Eden dental clinic of Mount Gilead hospital; Uselu from January 2006 to December 2008. The information collected with questionnaire included demography of patients, indications for extraction, type of tooth extracted and other treatments performed. Results were presented as simple frequency tables and graph. Data analysis was done with SPSS statistical software version 13.0. RESULTS: Tooth extractions represented one third (33.4%) of the total treatment procedure. Periodontal disease (45%) and caries (32.6%) were the main reasons for extraction. Other reasons in descending order are failed root canal treatment (1.5%), orthodontic reason (1.2%), tooth in fracture line (1.0%), trauma (0.6%), supernumeraries (0.4%) and prosthetic reasons (0.2%). There was higher extraction among females than males p > 0.05. Tooth extraction in 27-36 years age group was the highest and the main reason for extraction in this age group was impaction (47.8%). Higher number of extracted teeth was from lower right quadrant, lower arch and right side of mouth in this survey. Molars made up 95.3% of all extracted teeth with first molar predominating (40.1%). The proportion of extractions attributed to periodontal disease increased from 17-56 years, but declined thereafter. CONCLUSION: Tooth extraction was a highly frequent treatment procedure in this survey. Molars were mostly extracted as a result of caries although periodontal disease was the dominant reason for extractions. This result is different from results from previous studies. RECOMMENDATION: Findings in this study showed that tooth extraction constitute about one third of the total procedures done in this rural health facility during the study period. This is mainly due to late presentation and brings to the fore, the degree of ignorance on oral health issues among the Nigerian rural dwellers. It is the opinion of the authors that the attention of the dental professionals be drawn to the need to reach out, educate and encourage best oral healthcare practices.

INTRODUCTION: The aim of our study was to investigate the prevalence of root resorption during and at the end of orthodontic treatment and to assess its relationship with age, sex and treatment with or without extractions. PATIENTS AND METHODS: Our study included 82 patients (51 women and 31 men) aged between 6 and 38 years, who received orthodontic treatment. Evaluation of root resorption was performed on panoramics at the beginning and at the end of orthodontic treatment. All the teeth were observed. The degree of root resorption was increased respectively by the standards in four ordinal levels (4). Data analysis was performed by Epi Info 6.0. RESULTS: Root resorption was present in all the teeth and maxillary incisors are the most affected. The correlation between age and root resorption was significant (p = 0.008). Women were more affected by resorption (P = 0.002). Patients treated with extraction showed more root resorption (p = 0.12). CONCLUSION: Our results suggest that orthodontic treatment is involved in the development of root resorption. The most often teeth resorbed are maxillary incisors. Age, sex and orthodontic extractions can be considered as risk factors for root resorption.

The objective of the study was to compare the safety of 0.6 mg/kg oral midazolam sedation alone with a combination of 0.6 mg/kg oral midazolam and nitrous oxide-oxygen sedation during dental treatment of young children. The study had a crossover design where every patient received two different sedation regimens i.e. oral midazolam 0.6 mg/kg alone and oral midazolam 0.6 mg/kg with nitrous oxide-oxygen inhalation during two dental treatment visits. Thirty children (17 males and 13 females) were selected for the study with mean age of 55.07 (+/- 9.29) months. Safety of the two regimens was evaluated by monitoring hemodynamic parameters (heart rate, blood pressure & oxygen saturation) and through observing the child for 24 hours post-sedation for any side effects such as nausea and vomiting. Very few changes in hemodynamics were noted from baseline during both the visits. However, the mean oxygen saturation level with oral midazolam and nitrous oxide-oxygen was significantly (p < 0.05) higher than oral midazolam alone. Postoperative side effects were very few and mainly remained limited to post-sedation drowsiness. It can be concluded that oral midazolam (0.6 mg/kg) alone and oral midazolam (0.6 mg/kg) plus nitrous oxide (30%-50%) sedation are both safe while providing dental treatment to children with behavior problems.

It has become increasingly common for diabetic patients to be considered as candidates for dental implants. However even though success rates of implant therapy in diabetic are high, this does not preclude failures. Failure to osseointegrate in the initial healing phase results in a fibrous tissue encapsulation of the implant and clinical mobility, leading ultimately to the failure of the implant. This review presents the current knowledge regarding the effect of diabetes mellitus on the osseointegration of implants including pathophysiologic aspects as well as their potential implications on bone metabolism and osseointegration, implant success rate at the second-phase surgery and guidelines for pre and post-operative management. In experimental models of diabetes mellitus, a reduced level of bone-implant contact has been shown, and this can be reversed by means of treatment with insulin. Compared with the general population, a higher failure rate is seen in diabetic patients. Most of these occur at the second-phase surgery, seemingly pointing to the microvascular complications of this condition as a possible causal factor. It is necessary to take certain special considerations into account for the placement of implants in diabetic patient. A good control of plasma glycemia, together with other measures, has been shown to improve the percentages of implant survival in these patients.

OBJECTIVES: Cranial base development during fetal life is of major interest for many research purposes. In this study, we focused on fetal age estimations which are extremely important in forensic contexts. Nevertheless, there have been very few studies using occipital measurements to determine fetal age. OBJECTIVES: To evaluate change in the sagittal length/maximum width ratio of the basilar part of the occipital bone and to propose a simple and reliable method for fetal age determination. METHODS: A sample of 30 male and 7 female fetuses aged 24 to 41 weeks amenorrhea underwent CT scan. Occipital bones were reconstructed (Amira 4.0) and measurements were carried out on each part. RESULTS: A multivariate analysis (ANOVA) gave an age formula using right exoccipital measurements and a linear regression supplied the age of reversion of the sagittal length/maximum width ratio. CONCLUSION: This preliminary study clearly highlighted the promises of 3D CT-Scan studies of fetal cranial base and gave interesting results and the method deserves to be tested on a larger sample.

The end of the last century and the present decade is characterized by an evolution of the concept of health and illness in the public domain. The World Health Organization defines traditional medicine as "comprising various practices, approaches, knowledge and beliefs incorporating medicinal herbal, animal and/or mineral, spiritual therapies, applied alone or in combination to maintain well-being and to treat, diagnose or prevent disease. In dentistry, the plants used are numerous. The objective of this work is to describe the herbal medicine used against oral diseases. To conduct this study, 10 articles and theses, a brief, 2 books, 4 reports and 2 clippings on traditional medicine/herbal medicine were consulted. Several African plants, in the form of use, can help relieve or treat dental pain and have positive effects against dental caries and periodontal diseases. The geographic and financial accessibility associated with the lack of qualified personnel are the plants could be an alternative in the management of certain oral diseases.

BACKGROUND AND AIM: There has been an increase in medical and dental knowledge in the world today. More and more people are getting to know their rights and cases of medical and dental liability is on the increase. Hence a proper approach towards obtaining informed consent in dental practice has become necessary. This study assessed dentists' perception on informed consent taking for dental procedures. METHODOLOGY: Self administered questionnaires were given to all dentists working in one of the teaching hospitals in the south west region of Nigeria. The questionnaires assessed the doctors' ability to properly define informed consent, knowledge of aspects relevant to informed consent taking and procedures for which they felt informed consent should be taking routinely. RESULTS: The result revealed 10 out of 56 dentists (17.5%) were able to rightly and fully define informed consent. Almost all the dentists (98.4%) claimed to have taken informed consent at one time or the other, out of which 31 dentists (59.6%) claim that they always take verbal informed consent on routine dental treatment. However 21 (42%) of the dentists believed that informed consent scares patients, while 31 (54.5%) believed informed consent prepares patients better for the procedure. Generally the dentists agreed that the more invasive the dental treatment procedure was the more they felt informed consent should be taken. CONCLUSION: Dentists knowledge about informed consent seems to be inadequate as only few of them were able to define informed consent. However their attitude towards informed consent seems to be more positive as almost all claimed to have taken informed consent from patients at one time or the other. Therefore regular update about knowledge and significance of informed consent should be encouraged.

The obturating prostheses of the jawbone and the prostheses of rebuilding of the mandible make it possible to restore the losses of substance of the jawbone and of the mandible and to cure the functional and Aesthetic disorders which result from these losses of substance. The success of these prosthetic restorations can be compromised by technical, economic and cultural factors. The principal factors are the importance of the losses of substance, the reduced number of teeth, the poverty of the technical plate, the persistence of certain traditional concepts. The fight against these factors requires the promotion of therapeutic associations in maxillo-facial cancerology, the sensitizing of the populations to the early hospital consultations, the improvement of the technical plate of the prosthesis of the jawbone and the face, the facilitation of the access of the most underprivileged groups to the prosthetic restorations, the promotion of multi-field collaboration, the whole co-operation of the patient throughout the treatment and the follow-up postprothetic.

In the mixed dentition, lower incisor crowding can exist. He may be transitory or increase with dental arch evolution because of reduction of arch length by loss of leeway space. Early diagnosis allows the instauration of interceptive therapy, to ovoid extractions. Preserve or loss leeway space will depend of orthodontic space management. The clinical case presented in this article shows the interest of early treatment of incisor crowding to preserve arch length and make the leeway space available to resolve the crowding.

Traditional medicine of which is a part traditional odontology occupies an important place within the African societies. It often constitutes the first appeal (80 % of the population) because of the high cost of the care, the incapacity of the human and material resources but also the faiths of the populations. This reality makes valuation of the traditional odontology a necessity. This study comes within this framework. It's a contribution for a better knowledge of practices and plants used in traditional odontology in Ivory Coast. So, after a presentation of some traditional knowledge's and their fields of application, the authors review studies made on the efficiency of plants in the prevention of tooth decay and the treatment of some oral diseases. The objective of these researches is to elaborate effective and financially affordable traditional improved drugs.

BACKGROUND: Helicobacter pylori plays a significant role in gastric disease. The aim of the present pilot study was to evaluate the prevalence of H. pylori detected by real-time polymerase chain reaction (real-time PCR) in the sub-gingival plaque of chronic periodontitis patients and to determine periodontopathogens profile of positive sites at H. pylori. METHODOLOGY: 109 subgingival samples collected from 17 subjects with chronic periodontitis were studied. The DNA was extracted from the oral samples and analyzed for the presence of H. pylori by real-time PCR (LightCycler) using 16S rRNA#120 primers which targeted the 16S rRNA gene. DNA from H. pylori DSM 4867 was used as a positive control. Seven bacteria implicated in chronic periodontitis were selected to explore the presence of these periodontopathic species in the oral positive sites for H. pylori. RESULTS: 16 of 109 samples (14.7%) were positives of H. pylori. All the positives sites were also positives to Fusobacterium nucleatum and Eikenella corrodens, 62.5% to Porphyromonas gingivalis, 31.25% to Treponema denticola, 25% to Prevotella intermedia, 12.5% to Aggregatibacter actinomycetemcomitans and 6.25% to Tannerella forsythia. CONCLUSIONS: H. pylori may be present in the subgingival plaque samples of patients with chronic periodontitis who are resident in a developing country. F. nucleatum and E. corrodens could coaggregate with H. pylori in the subgingival dental plaque.

OBJECTIVE: To assess the expectations and perceptions of Nigerian patients regarding infectious diseases in dentistry. METHODS: A questionnaire based cross-sectional survey of patients attending the dental centre of University of Benin Teaching Hospital, Nigeria was conducted in 2009. RESULTS: Out of the 405 patients that responded, 75.6% expressed worry about contracting infection during the dental treatment. Respondents felt that they are at risk of contracting the following infection from the dental clinic, HIV (47.4%), hepatitis B and C (15.5%), herpes (3.5%) and tuberculosis (1.7%). One-quarter (25.4%) of the respondents would avoid dental treatment because of fear of contracting HIV. Ninety-two (22.7%) would switch from dental clinic with HIV infected personnel and 37.8% would allow HIV-infected dentist to treat them. Only 10.4% of the respondents would expect the dentist to refuse to render dental treatment to the HIV-infected patients. CONCLUSION: This survey revealed that a high proportion of Nigerian patients are worried about contracting infectious disease during dental treatment and this impacted negatively on how they seek dental care. Improved public education and communication on the risk involved with dental treatments is needed to allay the fear of Nigerian patients.

Canal entrances can be flared using specific, low speed, continuously rotating Ni-Ti instruments. Two such instruments were evaluated for their capacity to flare the canal entrance while respecting the initial canal axis. Lower molars (n = 20) with two distinct mesial canals were prepared to within 2.5 mm of the pulp chamber floor using Bramante's technique. Canal entrances were flared with a QUANTEC FLARE LX or an ENDOFLARE. They both had a 0.12 taper and a #25 tip diameter. The instruments were first inserted in the canals using an axial movement and then withdrawn with a selective circumferential brushing action. Photographs taken before and after each preparation were compared. No ledging or significant modification of the working length was noted. The centre of mass was displaced on average by 0.138 mm with no brushing action and 0.274 mm with brushing action. In most cases (87.5%), the centre of mass was displaced mesially. The two instruments behaved in an identical mode, both before (p = 0.3497) and after (p = 0.9304) the brushing action. Ni-Ti flaring instruments can be used to flare the canal entrance with little displacement of the initial canal axis, even when a brushing action is used.

Bisphosphonates are involved in the occurrence of Osteonecrosis of Jaws (ONJ), which is a complication of these treatments. This osteonecrosis concern the alveolar bone and develops generally after an oral surgery. It can however occur spontaneously without preliminary dental extraction. Other risk factors could play potentiates the risk of ONJ.
