Objective. There is a change in the trends and distribution of dental caries in established and nonestablished market economies. The aim of this study was to describe caries distribution, prevalence, and treatment needs among school children in Port Harcourt, Nigeria.Materials and Methods. The study was a cross-sectional survey of students between the ages of 12 and 15 years. Data was collected using a structured questionnaire and clinical oral examination. Analysis of data was done using statistical package for social science version 20.0. Association between variables was tested using chi-square, independentt-test, and one-way analysis of variance.Results. The study population consisted of 195 school children of mean age13.21±1.09years. The prevalence of dental caries was 15.4% (n=30). The mean DMFT score for the entire group was0.25±0.66. Dental caries occurred more significantly (P<0.005) on the mandible (66.7%) than on the maxilla (33.3%) and was significantly (P<0.005) more prevalent on the first molars (66.7%) than on the second molars (26.6%).Conclusion. The number of untreated dental caries was high and the restorative index was low among the students. The overall caries prevalence and mean DMFT were low even when compared to other studies in similar populations in Nigeria.
Background: There is clinical evidence that periodontitis and diabetes mellitus (DM) are interconnected. Thus, periodontitis can promote systemic chronic inflammation that can exacerbate type 2 diabetes mellitus.
Methodology: Data was collected with self-administered questionnaire. Glycaemic control and periodontal status were evaluated by glycated Hb values and CPI respectively. Analysis was done using the Statistical Package for Social Sciences version 20.0 (IBM SPSS Statistics Armonk New York). Association of glycaemic index with periodontal status was explored by the χ2 test and statistical significance was set at P < 0.05.
Results: One hundred and eighty-five participants with type 2 diabetes were recruited with a female predominance in both centers. Majority of participants were above the fifth decade. The mean duration of diabetes was 8.97±7.14. 73.3% of participants in UPTH and 84.7% in LASUTH were out of (p=0.001). One-fourth of participants in LASUTH and 14.2% of participants from UPTH had poor oral hygiene. Twice participants in LASUTH had good glycaemic control compared to those in UPTH (p=0.001). The periodontal status of majority of the participants in the two centers was between CPI score 2 and 4 (p=0.02). The association between good glycaemic control and gender and between good glycaemic control and age were statistically significant (p=0.014; p=0.001).
Conclusion: The periodontal status of participants did not worsen with poor glycaemic control. However, education was significantly associated with extent of control. Periodontal care should be incorporated into the management of the diabetics for improved quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
