Tooth brushing practice in Ethiopia: a systematic review and meta-analysis

Oral hygiene refers to taking care and maintaining the cleanness of gum and teeth; a good oral hygiene practice promotes better oral health in general. Oral hygiene is the top public health concern of the population. Tooth brushing is a technique to keep oral hygiene from related complications. Therefore, this study provides the pooled prevalence of tooth brushing practice in Ethiopia. Databases searched for articles systematically across PubMed, Google Scholar, Hinari, EMBASE, and African Journals Online. Two reviewers independently conducted the selection, screening, reviewing, and data extraction using a Microsoft Excel spreadsheet and used the Joanna Briggs Institute prevalence critical appraisal tools to assess the quality of evidence. All studies conducted in Ethiopia from 2010 to 2020, reporting tooth-brushing practices extracted for and imported into the Comprehensive meta-analysis version 3.0 for further analysis. Beggs and Eggers's tests evaluated for publication bias with Higgins's method evaluated for heterogeneity. A random-effects meta-analysis model with a 95% confidence interval was computed to estimate the pooled effect size (prevalence). Furthermore, the authors employed subgroup analysis based on the study area and sample size. After reviewing 36, 10 articles fulfilled the inclusion criteria, and were included in the meta-analysis. The pooled prevalence of tooth brushing practice was 12.2% (95% CI 7.6-19.2%). The review reported a lower level of tooth-brushing practice in Ethiopia. We recommended that special attention should be given to the oral hygiene of the Ethiopian people.
