Item Dental caries prevalence and bilateral occurrence in premolars and molars of adolescent school children in Ibadan, Nigeria(2015) Denloye, O.O.; Ajayi,D.M.; Popoola, B.O.The aim of the study was to determine the prevalence of dental caries in premolars and molars of adolescent school children in Ibadan, Nigeria with a view of comparing findings from this study with previous African studies. A cross section of 12-19 year-old school children from the five local government areas in Ibadan were examined over a period of three months by two examiners (OD and DA), using the WHO criteria for diagnosing dental caries. Only premolars and molars were examined but the third molars were excluded because they were not fully erupted in most children. The mean age of the children under study was 16.2 ± 0.83 years. Dental caries was detected in 10.8% of the children. Overall, 225 teeth had dental caries, out of which 13.3% were premolars while 86.67% were molars. Among the molars, first molars were mostly affected by caries (68.72%) while 31.28% second molars were affected. Second premolars were more affected by caries among the premolars. Also bilateral caries occurrence was highest in the mandibular first molars. In conclusion since the first molars were the most vulnerable teeth to decay, caries preventive programs on them need to be drawn up.Item A comparison of clinical and radiographic caries diagnosis on posterior teeth of children seen at a Nigerian Teaching Hospital.(2010) Popoola, B.O.; Denloye, O.O.; Ajayi, D.M.; Sote, E.O.caries is the most effective means of ensuring resolution of the condition and its sequelae. The aim of this study was to compare the effectiveness of clinical and radiographic (using bitewing radiograph) methods of caries diagnosis in children. The subjects were 172 children within the age range of 5-12 years attending the Paedodontic Clinic of the University College Hospital for the first time. They were clinically examined for the presence of dental caries using the WHO criteria. Left and right bitewing radiographs were taken following the clinical examination to detect dental caries. Clinical examination found additional 4 occlusal caries (incipient caries) that were not diagnosed radiographically and radiographic examination revealed additional 20 approximal surface caries that were not evident clinically in deciduous teeth. In permanent teeth, 3 additional occlusal caries were diagnosed clinically while only one additional approximal caries was diagnosed radiographically. These observations revealed the additional diagnostic value of bitewing radiograph in the diagnosis of approximal caries in children and the importance of clinical examinations in diagnosis of early occlusal caries (incipient caries) which are difficult to see on dental radiographs. In view of these findings, the use of bitewing radiographs combined with careful clinical examination will be of great advantage in early detection of caries in childrenItem A Study of dental caries prevalence in 12–14 year old school children in Ibadan, Nigeria(2005) Denloye, O.; Ajayi, D.; Bankole, O.The aim of the study was to determine dental caries prevalence among a representative sample of 12–14 year old school children in Ibadan, Nigeria with a view of determining Restorative Index and Met Need Index of the studied population. Dental caries was diagnosed according to the WHO method. Out of the 577 children in the age group, 65 children (11.2%) had dental caries experience as expressed with the DMFT index. More than 85% of the children were caries free. A mode of one DMFT was the highest score for the children although a 14-year-old pupil had DMFT score of 6. Female children had higher mean DMFT score of 2.03 1.13 compared with 1.78 1.0 for males (P 0.05). The Restorative Index (RI) and Met Need Index (MNI) for the children were very low as only the 14-year-old children had an RI of 3.45% and MNI of 0.11. Restorative Index reflects the restorative care of those who have suffered the disease and it is measured as a ratio of filled to filled plus decayed teeth percent that is F/F D percent. Met Need Index is an indication of treatment received by an individual and it is measured by the ratio of the mean missing plus filled teeth to mean decayed, missing and filled teeth that is M F/DMF. Since cost of management, which may be out of the reach of these children, has been identified as one of the factors militating against their receiving treatment, the result of this study suggest that oral health education with emphasis on correcting snacking habits of school children is desirable.Item Sociobehavioural risk factors of dental caries among selected adolescents in Ibadan, Nigeria(Elsevier Ltd, 2014) Ajayi D.M; Abiodun-Solanke, I.F.Objective: The objective of this study was to determine the influence of sociodemographic and behavioural factors on the prevalence of dental caries among the adolescents in Ibadan. Method: Multistage sampling method was used to select participants from six secondary schools. In each school, an arm was selected randomly from each class and 30 students also randomly chosen per arm, with equal distribution of males and females. A structured questionnaire was administered. It consisted two parts, the first part assessed information on the sociodemographic characteristics, oral health behaviours and snacking habits of respondents, while the second part consisted of intra-oral examination to determine the caries status and oral hygiene (OH) levels of respondents. Result: The age range of the participants was 10e19 years with a mean of 13.73 2.02 years. The father’s level of education had a statistically significant association with dental caries; prevalence of dental caries was high in the 10e14-years age group, in children of parents from high socio-economic (SE) class, those who reported brushing twice daily, those with poor OH and those who ate snacks in between their meals. Conclusion: This study reveals that high SE status, poor OH and daily consumption of biscuits were important factors in caries experience among the school children studied.
