Rehabilitation with complete denture include among other objectives, improvement of facial and dental esthetics. To these ends, the artificial teeth should mimic as far as possible, healthy and natural dentition. The main objective of this study was to investigate factors associated with tooth color among black African subjects. One hundred and two subjects (72 men and 30 women) were included in this investigation. The colorimetric parameters of their teeth as well as those of the conjunctiva of their eyes and skin were recorded from standardized photographs. Two software, Mesurim and Photoshop were used for that purpose. Univariate and linear regression analysis were run to assess the association between tooth color and the variables age, gender and colorimetric parameters of eyes and skin. It appears from the result of this study that tooth color was positively and significantly associated with age. Stepwise multiple regression analysis further revealed that tooth hue can be best predicted by a combination of skin complexion and brightness and eye lightness.

BACKGROUND: The effects of digit sucking on dentofacial structures has been widely studied, but its relationship with the function and/or shape of the palate has been negleted. A clinical observation of high palatal vault has been reportedly associated with digit sucking. However, the description has been made on the basis of subjective clinical observation rather than actual measurements. The aim of this study is to assess the effects of digit sucking habits on palatal dimensions of children with digit sucking habit; and compare the findings obtained to a control population. METHOD: Cross-sectional sucking behaviour data was collected on 250 school children aged 3 to 5 years using questionnaires completed by parents. Parameters including palatal widths, depth and heights were measured directly from the maxillary casts obtained from the children and palatal index was calculated. All values were compared using t-test. RESULTS: Significant differences were seen in palatal depth, palatal width, palatal height and palatal index at the level of the maxillary primary first and second molars. No significant difference was observed for palatal index at the level of the maxillary primary canine. CONCLUSIONS: It was concluded that digit sucking may cause changes in palatal dimensions.

OBJECTIVE: The microbial eatiology of aggressive perodontitis is different worldwidly. The purpose of this study was to determine the presence or absence of two anaerobic, highly pathogenic bacteria, Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis (P.g) in aggressive periodontitis in a Moroccan population. MATERIAL AND METHODS: Our study involved a sample of 32 subjects, 20 with aggressive periodontitis and 12 with a healthy periodontium. A pool of bacterial samples was performed in each patient looking for Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis by the method of bacterial culture. RESULTS AND CONCLUSION: Microbiological analysis showed an association of the presence of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis with aggressive periodontitis in Morocco. Porphyromonas gingivalis would be less present than Aggregatibacter actinomycetemcomitans in aggressive periodontitis in Morocco (30% vs 83%)(p < or = 0.05%). However, given the small sample size other studies are necessary.

UNLABELLED: Osteonecrosis of the jaw (ONJ) is a complication related to the use of bisphosphonates (BPs). Patients receiving BPs for the treatment of malignancies are at an increased risk of developing bisphosphonate-related ONJ (BRONJ) as compared to patients receiving BPs for the treatment of other disorders such as osteoporosis. Additionally, tooth extractions have been suggested to increase the risk of BRONJ in individuals taking BPs. OBJECTIVE: To review the role of dental extraction as a risk factor for BRONJ in cancer patients. MATERIALS AND METHODS: Databases were searched from January 1999 up to and including July 2012 using various combinations of the following keywords: "bisphosphonate", "osteonecrosis of the jaw", "cancer", "oral" and "dental extraction". RESULTS: Twenty two studies were included. Eighteen studies assessed the relationship between BRONJ and dental extractions in cancer patients, reporting the overall prevalence of BRONJ following extraction in this group as 3.25 +/- 2.23%. Four studies did not report a correlation between BRONJ and extractions, and recommended protocols to avoid the complication. CONCLUSION: There is a plausible relationship between dental extractions and the development of BRONJ in cancer patients. Written informed consent must be obtained prior to dental procedures in patients at risk for developing BRONJ.

OBJECTIVE: To assess occupational stress among dental house officers and students treating patients in a tertiary healthcare centre in Nigeria. MATERIALS AND METHODS: This questionnaire-based cross-sectional study of dental officers and final year dental students at the University of Benin Teaching Hospital, Benin City was conducted in the second half of 2010. The questionnaire utilized was a modified form of stress screening questionnaire of International Stress Management Association. RESULTS: Out of the 100 questionnaires distributed, 88 questionnaires were returned, giving a response rate of 88.0%. A total of 53 (60.2%) the respondents were male and 35 (39.8%) were females. Dental students constituted 54 (61.4%) of the respondents while the remaining 34 (38.6%) were house officers. Amongst the respondents, 9 (10.2%), 68 (77.8%) and 11 (12.5%) reported severe, moderate and mild occupational stress respectively. The reported stress was significantly associated with gender (P = 0.032) as more female reported severe stress and more male reported moderate stress. The mean stress level was significantly higher among dental students than house officers (P = 0.007). CONCLUSION: One in every ten respondent reported severe occupational stress with a significant gender difference. Development of stress reduction strategies for dental house officers and students with gender bias is imperative.

AIM: To determine the frequency of dental caries and habits that can be the cause of this disease in Brazzaville. METHODS: A prospective study was conducted in primary schools between February and May 2010. This study involved a sample of 307 students of both sexes, aged 4-15 years from school in the city of Brazzaville. RESULTS: Prevalence of dental caries was 53.4% and the index of DMFT 2.06. Use of toothbrush was 99.4%. Two children (0.7%) brushed their teeth three times a day. There was a statistical link between regularity of brushing and occurrence of caries. The prevalence of caries was of 53% in children who brushed once a day and 12.8% in those who brushed twice a day. No decay was noted in those who brushed three times a day (p = 0.001). The DMFT was 2.06 in children who used non-fluoridated toothpaste and 1.13 in those who used the fluoridated toothpaste (p = 0.002). CONCLUSION: To ensure students a better oral hygiene and healthier teeth, a module in oral health education in schools is one of the way to fight against this public health problem.

AIM: To assess expectant mothers on their knowledge and awareness of factors affecting paediatric oral health. METHOD: Seven hundred and six women in different stages of pregnancy were recruited from the antenatal clinic of the University of Port Harcourt Teaching Hospital over a period of four weeks. A self-administered structured questionnaire on socio-demographic information, oral health knowledge and oral health behaviour was filled by the participants. Data was analyzed using SPSS version 17. RESULTS: The mean age of the subjects was 29.6 (SD + 4.4) years. Seventy percent of them had tertiary education and 63.9% were unemployed. A significant proportion (83.4%) of the women had medium to high score (> 50%) in the knowledge of causal and preventive factors in dental caries and gingivitis. Over seventy nine percent (79.2%) of them acknowledged that primary teeth are important, but 43.6% did not know whether primary teeth should be restored or not. Only 39.3% of the women knew that leaving a feeding bottle/breast in the mouth of a sleeping child could be harmful to the teeth. Knowledge of the role of bacteria in gingivitis (81.3%) and dental caries (86.6%) was high. Over 45% of participants agreed that mothers could transmit cariogenic bacteria to their children. Only 0.7% of the women had taken their children to the dental clinic for routine checkup. CONCLUSION: Most of the participants had medium to high knowledge of the factors that affect paediatric oral health, yet the participants did not demonstrate adequate and proper concomitant oral health practice.

INTRODUCTION: The aims of this study were to (1) define facial architecture in Caucasian patients with normodivergent, skeletal and dental class I using Treil's cephalometric analysis, which is based on computed tomography (CT), and (2) develop a scheme to determine individual balance or normality in relation to linear, angular and volumetric parameters. MATERIAL AND METHODS: The CT data of 60 adult subjects were equally divided between both genders. Based on anatomical points located along the trigeminal neuro-matricial facial growth axes, a three-dimensional maxillo-facial architecture was constructed. RESULTS: Volumetric and linear parameters were greater in males (0.000 < p < 0.044) except for the anterior and posterior mandibular width. Sexual dimorphism was not observed with angular parameters. There was no correlation between volumetric and angular parameters. The correlation tests showed that the total volume of the frame increases with infraorbital depth, supraorbital depth, posterior mandibular width and facial height (0.526 < r < 0.777), while it was not associated with the maxillo-orbital width (0.252 < r < 0.389). Total and orbital volumes were more correlated with posterior than with anterior mandibular width. Maxillo-mandibular volume of the frame was more cor-related with orbital depth (0.591 < r < 0.742) than the orbital volume (0.482 < r < 0.589). CONCLUSIONS: The results allowed us to establish three-dimensional cephalometric standards, and to replace the tenet of normality, which is a mean value of calculated parameters, by the concept of individual balance among volumetric entities. While sagittal and vertical dimensions affect volumetric changes of the frame, the transverse dimension does not.

UNLABELLED: The aim of this work was to study the association between dental and periodontal status and digestive pathology in the Ferlo populations in Senegal. METHOD: This was a cross sectional study involving 300 people living in the area of the Ferlo in the Centre East of Senegal. Selected individuals must be over the age of 15 years and resided in the area. Cluster sampling helped recruit individuals. Collected information related to digestive pathology (yes or no), periodontal status (plate index, inflammation, bleeding, loss of attachment, the depth of pocket and the CPITN.) Dental status was evaluated by the DMFT. The data analyzed with software R and the Student's t test used to compare the averages of the indices in both groups at the threshold of 5%. Multivariate logistic regression analysis was used to isolate the final model with a threshold of 5%. RESULTS: Averages of dental and periodontal index were broadly equal in both groups (sick and not sick). The DMF and missing teeth were significantly associated with the digestive pathology after adjustment on gender, age, BMI, marital status, the number of cigarettes smoked and the depth of pocket. CONCLUSION: This study revealed a significant association between dental status and digestive pathology. The comprehensive care of patients therefore raises the interest of collaboration between surgeons, dentists and gastroenterologists for effective and adequate treatment.

OBJECTIVE: To assess the oral health practices and the prevalence of dental problems among competitive university athletes in Nigeria. MATERIALS AND METHODS: A cross-section of athletes that participated at the 2011 Nigerian university games in Benin-city, Nigeria, was studied. The tool of data collection was self-administered questionnaire. The information sought included demographics of the respondents and the sports they are involved in. Other information included prevalence of dental problem, cigarette smoking and alcohol consumption, history of toothache, gingival bleeding and mouth ulcer as well as their care seeking behaviour and pattern of oral health utilization. RESULTS: The response rate was 75.3%. The prevalence of oral health problem among the respondents was 28.3% and dental caries was the commonest reported oral health problem among the respondents. A total of 106 (46.9%), 82 (36.3%) and 92 (40.7%) of the respondents had experienced toothache, gingival bleeding and mouth ulcer respectively. Less than half (40.7%) of the respondents have ever visited the dentist. Among the respondents, 108 (47.8%) reported taking alcohol while 16 (7.1%) indulged in cigarette smoking. Consumption of soft drink always and sometimes were reported by 64 (28.3%) and 98 (43.4%) of the respondents respectively. Respondents who had experienced dental problem during competitions made up 15.9% of the respondents and 66.7% of this group reported that the dental problem affected their performance in the competition. CONCLUSION: The prevalence of dental conditions among respondents was high and it had adverse impact on performance in competitions.

AIM: To assess the effect of various socio-demographic in addition to oral hygiene variables on the oral hygiene and periodontal status. METHODS: A combination of multi stage and cluster sampling procedure was followed to collect a representative population of 831, 12 year-old schoolchildren of Udiapur district. Oral Hygiene Index Simplified (OHI-S) and Community Periodontal Index (CPI) were used to evaluate oral hygiene and periodontal status respectively. Along with the clinical examination, each subject was interviewed to collect the socio-demographic information and oral hygiene practices. RESULTS: The overall mean OHI-S was 1.42 and debris component of the oral hygiene index was dominant. Unpaired 't' test showed significantly higher DI-S (p = 0.0001) and OHI-S (p = 0.007) among boys than girls. The overall prevalence of periodontal disease was 89.9% and gingival bleeding was widespread. Chi square test demonstrated significant differences (p = 0.0001) with 14.6% urban children having healthy periodontium in comparison to 5.6% rural residents. Oral hygiene scores were dependent on the father's occupation (p = 0.046), father's (p = 0.002) and mother's level of education (p = 0.0001). CONCLUSIONS: Oral hygiene status was poor, more among boys with debris contributing a major part for oral hygiene index. Periodontal status was poor with bleeding being most prevalent indicator. The multivariate analysis of oral hygiene status confirmed the existence of socio-behavioural determinants for oral hygiene.

OBJECTIVE: Systematic full-mouth dental examination during pregnancy is an official preventive measure recently advocated by the French Health policy. The aim of this study was firstly to evaluate the oral health related to some sociodemographic factors among pregnant women, and secondly to propose this dental examination together with the routine antenatal interview. MATERIAL AND METHOD: This cross-sectional study combined several medical questionnaires with an oral examination. It concerned all pregnant women attending their routine antenatal interview in the maternity unit of the Montpellier hospital. Socioeconomic status was assessed by Epices index. So that two groups were determined : the deprived group (D), and the non-deprived group (ND). RESULTS: Oral examination revealed that 93% of the women were suffering from at least one oral disease, 74% had a periodontal disease (9% had a periodontitis), and 74% had at least one carious tooth. The mean Epices score was 30.5 and the mean number of carious teeth was significantly higher in the group D (3.4) than in the group ND (2.35), (p=0.02). The prevalence of periodontal disease or periodontitis were not significantly different between the two groups (p=0.81 and p=0.99 respectively). After stratification on the degree of dental hygiene knowledge, it was found that knowing about an adequate dental hygiene and specific preventive measures regarding pregnancy could reduce the gap between the oral health status of the two socioeconomic groups. CONCLUSION: This study showed that performing an oral examination, at the same time than the antenatal interview, could highly improve the knowledge about dental hygiene among pregnant women and the screening of oral diseases, especially for deprived population.

OBJECTIVE: To determine the perception of pain and discomfort associated with orthodontic separator placement in patients attending the Lagos University Teaching Hospital, Lagos, Nigeria. METHOD: Sixty four patients scheduled for treatment with fixed orthodontic appliances completed questionnaires before insertion of separators and after placement at 4 hours, 24 hours and 7 days. The level of pain and discomfort during these time periods was assessed by a visual analogue scale. RESULTS: There was a significant increase in the level of pain/discomfort 4 hours and 24 hours after placement of the separators for all the activities. The level of pain/discomfort peaked at 4 hours but did not return to baseline levels after 7 days. Patients more than 16 years old reported significantly more pain/discomfort over time than those 16 years and under. No significant difference in pain/discomfort was found between the sexes. CONCLUSION: Patients experience pain/discomfort following placement of orthodontic separators. Pretreatment counselling and analgesics are recommended.

OBJECTIVE: To assess the knowledge, experiences and intention to have tooth bleaching among young adults studying in a Nigerian University. MATERIALS AND METHODS: A cross-section of part-time undergraduate students of University of Benin, Benin City, Nigeria were studied in 2010 using a self-administered questionnaire. RESULTS: About three-quarters 289 (72.4%) of the respondents reported awareness of at least one cause of tooth discoloration. A total of 143 (35.8%) of the respondents have heard of tooth bleaching with main sources of information being friends/relatives, dentists and the internet. One-third 132 (33.1%) of the respondents correctly identified that the aim of tooth bleaching was to make the teeth whiter. The respondents that had correct knowledge about mechanism, duration and complications of tooth bleaching were 51 (12.8%), 25 (6.3%) and 35 (8.8%) respectively. The major perceived benefits of tooth bleaching reported by the respondents were self confidence boost 152 (38.1%) and improvement of one's beauty 107 (26.8%). Out of the 68 (17.0%) respondents that have attempted tooth bleaching, 36 (52.9%) used tooth whitening toothpaste. Out of the 151 (37.8%) respondents that expressed intention of having tooth bleaching procedure, 32 (21.2%) would pursue the course, no matter the cost. CONCLUSION: In the studied population, knowledge of tooth discoloration was high, awareness and experiences of tooth bleaching were low but significant number expressed intention of having tooth bleaching. It is important that dentists increase oral health information particularly tooth bleaching information accessibility to the young adult population to improve the knowledge and prevent adverse effects.

Periodontal diseases are among the most common infectious diseases that lead to the destruction of periodontal tissues. Anaerobic gram-negative bacteria (Aggregatibacter actinomecetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum...) isolated from periodontal lesions, have been shown to be related to the onset and progression of periodontal disease. Given the incidence of periodontitis, increased resistance of oral bacteria to antibiotics and adverse effects of some antibacterial agents currently used in dentistry, there is a need for alternative products that are safe and effective, for prevention and treatment of these diseases. Essential oils considered traditional medicines are viewed as good alternatives. In Morocco, a wide producer of essential oils, the high prevalence of aggressive periodontitis, related to virulent periodontal bacteria isolated from pockets in Moroccan adolescents and because of the reasons evoked above, the search of a new natural agent has become a necessity. In this qualitative systematic review, the virulence and increased antibiotic resistance of periopathogens, involved in periodontitis, will be exposed, justifying the use of alternative natural agents such as essential oils-based. Studies that have investigated the efficacy of such plant-derived medicines on periodontal pathogens will be described and discussed.

Dental amalgam is a metallic restorative material that is used for direct filling of carious lesions since many years. The use of this material generates solid and particulate wastes that present potential challenges to the environment. This study was carried out to assess amalgam use and waste management protocols practiced by Moroccan and Burkinabe dentists. A cross-sectional study was made of 79 in Rabat, Sale and Temara in Morocco and 56 in Ouagadougou, Bobo-Dioulasso in Burkina-Faso. The results showed that 69.5% of dental amalgam waste in Morocco vs 49.9% in Burkina-Faso was disposed with household waste which is a problem for both the environment and a risk to human being. Proper methods of dental amalgam waste disposal should be carried out to prevent indirect mercury poisoning for human.

INTRODUCTION: The aims of our study are to measure the volume of the facial cavities based on a three-dimensional tomodensitometric acquisition in normodivergent, skeletal and dental Class I subjects; to quantify volumetric normality and generate an individual normality concept of these cavities. MATERIAL AND METHODS: The study was performed on a sample of 60 subjects equally divided between both genders. Based on the X, Y, Z coordinates of the anatomic landmarks and structural contours selected on the native slices and with the help of the GammaCepha software, we were able to compute the volume of the different cavities. RESULTS: The ratio of the different volumes compared to the total volume is 20.9% for males, 19.1% for females in maxillary sinuses ; 13.4% for males, 14.7% for females in orbital cavities; 29.7% for males, 30.2% for females in ethmoido-nasal cavity and 36% for males, 36% for females in oral cavity. CONCLUSION: This new method of calculating volumes of the different facial cavities is an original approach to three-dimensional biometrics. To our knowledge, the criteria of normality chosen in this study, which have not been defined until present, have allowed us to establish standards of volumetric facial cavities. This will allow identifying individuals in comparison to a normal volume reference, and define an individual balance regarding facial volumes.

The current diversity of opinions in endodontic diagnosis has been a source of interest and academic debate by clinicians and researchers. Currently, no single pulp testing technique can reliably diagnose all pulpal conditions neither it has been proven to be superior in all aspects. Despite improvements of various aspects of this process, there are no historically dramatic changes, or consensus for pulpal status in health or disease in addition to a lack of relative systematic reviews. In this review, the past, present and future most debated and critically questioned issues of endodontic diagnosis are discussed. The aim of this review is to provide insights in future diagnostic modalities and areas for further study in endodontic practice pertinent to diagnosis.

It is a transverse descriptive study realized from clinical files of 100 Moroccan children aged between 6 and 15 year-old having consulted the Rabat Dental Hospital (U.T.H. Ibn Sina) in Morocco between January and December 2009. The criteria of inclusion are age, Moroccan origin, first four permanent molars having made their eruption and a complete clinical file. The criteria of exclusion are the non-eruption of a first permanent molar and an incomplete clinical file. The clinical parameters are: age, sex, tooth brushing, quality of alimentation and the condition of the first permanent molars (caries, extraction, filling). The results showed that 65% of the children between 6 and 15 years have at least a first decayed permanent molar. Eight per cent of the children have at least a filling material on the first permanent molar and 4% of the children have already extracted a first permanent molar. The caries touch both sexes, both right and left sectors and both superior and lower arches without statistically significant difference (p > 0.05). The presence of the caries increased, on the other hand, with the age (p < 0.05). The relation between presence of caries, tooth brushing and quality of alimentation is not significant (p < 0.05). These results are in accordance with numerous studies and show a particular cario-sensibility of the first permanent molar.

OBJECTIVE: To determine the incidence and causes of dentoalveolar abscess among children attending an outpatient dental clinic in Nigeria. MATERIAL AND METHODS: This is a retrospective study of paediatric dental patients treated in University of Benin Teaching Hospital, Benin City from October 2010 to September 2011. RESULTS: The incidence of dentoalveolar abscess was 6.4% (53/824). However only 42 cases had their case notes retrieved for final research analysis. It occurred mostly in the lower right quadrant of the mouth. The affected children were majorly males and first or second child of monogamous family. A total 17 (40.5%) of the affected children were in the 6-11 years age group. This was the first dentist consultation among 35 (83.3%) of the children. The presenting complaint was toothache among two-thirds of the children. History of asthma, tonsillitis, peptic ulcer disease and previous surgery were medical history elicited from 6 (14.3) of the patients. The most implicated tooth was deciduous first molar. The causes of abscess include untreated dental caries 35 (83.3%), trauma 5 (11.9%), failed restoration 1 (2.4%) and periodontal diseases 1 (2.4%). Periapical radioluscency was predominant radiological finding among affected children. Tooth extraction was commonest treatment done. CONCLUSION: The incidence of dentoalveolar abscess among children was significant. The high frequency of untreated dental caries as the cause of dentoalveolar abscess indicates the need for school and community-based preventive strategies like encouraging infant oral health and preventive dentistry programs and early treatment intervention and dental health education.
