Brazilian school teachers' knowledge about dental trauma in children: systematic review and meta-analysis

Resumen

The objective of this review was to assess the knowledge on emergency management of dental trauma among Brazilian school teachers. The Pubmed, Scopus, Web of Science, Embase, Scielo, Cochrane and LILACS databases were used for research. Studies evaluating Brazilian school teachers’ knowledge regarding emergency management of dental trauma were included. Data were extracted on the following items: procedure in case of tooth fracture/dental avulsion, time elapsed to seek treatment and storage medium for the tooth. The JBI critical appraisal checklist for cross-sectional studies was used for assessment of the risk of bias. Prevalence meta-analyses were performed using the statistical method of Restricted Maximun-Likelihood (p<0.05). The search strategy retrieved 474 articles. After analysis, 19 articles met the inclusion criteria and 84% of the studies were classified with a low risk of bias. For the questions, procedure in case of tooth fracture/ tooth avulsion, time elapsed to seek treatment and storage media, 49%, 17%, 65% and 44% of teachers answered correctly, respectively. The prevalence meta-analysis found that less than 50% of Brazilian teachers have adequate knowledge about the proper management of cases of dental trauma in children.
