Objective
We sought to revise, qualify and summarize the body of evidence based on current information on the known associations and risk factors for traumatic dental injury (TDI) occurrence with an overview of systematic reviews.
Methods
Electronic searches were performed with no language nor date restrictions.According to the PECO strategy, systematic reviews that investigated participants (P) with (E) and without (O) the presentation of factors relating to TDI and these factors’ association with TDI episodes (O) as primary or secondary outcomes were included. Quality assessment and bias control were carried out according to the AMSTAR 2 checklist. In cases of systematic review results of discordance, the Jadad decision algorithm was applied.
Results
After titles, abstracts and full texts were read, 19 systematic reviews were included in this overview. Four were classified with critically low, eleven with low and four with moderate methodological quality, respectively. In all studies, 249 cross‐sectional, 34 epidemiological surveys, 22 cohort, 9 case‐control, 4 longitudinal, 3 ecological and 30 unspecified studies were included. Male gender, child age, greater overjet, inadequate lip coverage, anterior open bite, caries in the permanent dentition, overweight, a previous history of TDI, tongue piercing, the use of alcoholic beverages and participation in sports were all associated with a greater chance of suffering TDI.
Conclusions
Sociodemographic, clinical and environmental factors are associated with a greater chance of TDI occurrence. However, most of the systematic reviews included were of a low quality and may not provide an accurate and comprehensive summary of the available research that addresses the question of interest. Well‐designed primary studies on different aspects of TDI are encouraged to provide higher quality scientific evidence.
Background: Information about the functional and morphological consequences that occur following the premature loss of anterior teeth is still insufficient. Aim: To evaluate the consequences in children's speech and arch integrity following premature loss of primary anterior teeth compared to those without premature losses. Design: Electronic searches were performed based on the PECO criteria.
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.
