Abstract
Dental caries is still a major public health problem owing to its high prevalence and incidence in several regions. Planning and development of effective preventive and treatment modalities for the management of dental caries demand information on disease pattern and treatment needs of the populations. However, there is a paucity of this information in Uganda. The aim of the present study was to identify the dental caries pattern and treatment needs among Ugandan adolescent students. This was a descriptive cross-sectional study conducted among 11- to 19-year-old adolescents attending two secondary schools in Kampala and Mukono districts of Uganda. At both schools, random sampling was used to select the participating classes and the adolescents. Decayed teeth and treatment needs were recorded using the World Health Organization Basic Oral Health Survey criteria. A total of 406 adolescents comprising of 249 female and 157 male students participated in the study. Data were analysed using STATA, version 12.0. The prevalence of decayed teeth (DT) was expressed as a percentage of individuals with DT score ≥1. The treatment needs were categorised into three groups. Associations between dependent and independent variables were evaluated using cross-tabulation, chi-square test, and Poisson regression analysis. The overall prevalence of decayed teeth was 62.6% and mean DT was 1.7 ± 2.3. A total of 696 decayed teeth were observed, and the molar teeth, particularly the second molar (50.6%), were the most significantly affected. The prevalence of caries was higher in the mandible (51.4%) compared to the maxilla though the difference was not statistically significant. Decayed teeth were significantly (p < 0.05) associated with difficulty in chewing, history of dental pain in the past 12 months, poor perception of tooth state, and the female participants. Majority (59.4%) of the study participants required restorations of teeth. About 83.2% (n = 579) of the teeth needed restorations, while 44 needed extractions. In conclusion, the prevalence of decayed teeth was high among the study population. It is recommended that school health programmes should include oral health preventive and curative interventions to achieve optimum health.
Highlights
Worldwide, dental caries and periodontal diseases still constitute a major public health problem due to their high prevalence and significant impact on general health [1, 2]
Oral healthcare services in Uganda are provided at both government and private facilities by two cadres: the public health dental officers and dentists [9]
In order to counteract the potential increase in the prevalence of dental caries in developing countries and to meet 2020 global targets of the World Health Organization (WHO)/International Dental Federation (FDI) [15], there is need to have current epidemiological data depicting the disease pattern and treatment needs for specific populations [16, 17]
