摘要
Background Dental caries (DC) is highly prevalent condition affecting mostly young children. There has been no systematic review done on the prevalence of DC amongst 12-year -olds in Africa. Although some African countries have reported a decrease in DC prevalence, others have shown an increase and it is essential to measure current trends in order to identify strategies and programmes that could assist in reducing DC in Africa. The aim of this systematic review was to determine the prevalence of DC (condition) amongst the permanent dentition of 12-year-old children (population) in Africa (context). Methods A systematic review and meta-analysis was performed. Peer reviewed cross-sectional articles from January 2000 until December 2021 was searched and this included the following databases: Pubmed (Medline); SCOPUS; CINAHL (via EBSCOhost); Academic Search Complete (via EBSCOhost); Dentistry and Oral Sciences Sources (via EBSCOhost); and Science Direct. The search was last updated on the 10th January 2022. Joanna Briggs Institute critical appraisal tools were used to assess risk of bias. Prevalence figures were stratified by Urban/Rural status, country and time using a random-effects model. All studies performed on children 12-year-olds on the African continent were included. The prevalence of DC and the DMFT scores were the primary and secondary outcome measures, respectively. Only articles consisting of 12-year-old children who reside in Africa were included in this study. The systematic review was registered with Prospero CRD42021293666. Results 18,080 participants were included in this review. A total of thirty studies were included in the review. The pooled effect size of dental caries severity was 1.09 (CI 0.91-1.27) and the overall prevalence was 36% (CI 29.4-41.7%). Eritrea (78%) had the highest prevalence of DC while Zambia had the lowest (11%); Eritrea also had the highest DMFT score (2.5) with Sudan having the lowest score (0.49). Urban cities had the highest DMFT score (1.32, CI 0.97-1.68), compared to rural cities (1.13, CI 0.86-1.4) and there was an increasing trend in DC prevalence over time from 28% (CI 23-34%) in 2000 to 2005 to 57% (CI 43-72%) in studies conducted after 2015. The risk of bias was very low where majority of the studies scored more than 50% in the JBI critical appraisal tool. Conclusions There was a wide discrepancy in the DC prevalence and scores across the different countries, settings (rural versus urban) and there was an increase in the prevalence over time. This review was self-funded.
