ObjectiveThe aim of this study was to perform a systematic review and search for scientific evidence on the association between socioeconomic indicators and traumatic dental injury (TDI) in the primary dentition.
MethodologyThe PubMed, ISI, LILACS, Cochrane Library, and Embase databases were searched for articles addressing possible associations between socioeconomic indicators and TDI in the primary teeth in journals dating from the inception of the databases through to December 2013. Two independent reviewers performed data extraction and analyzed the quality of the studies. Meta-analysis was undertaken. Pooled estimates were calculated with a 95% confidence interval (CI) and odds ratios (OR).
ResultsSixteen articles were included in the systematic review. Children from families with household income less than two times average salary (U$ 592) (OR: 0.77; 95% CI: 0.66-0.90) or more than three times the average salary (U$ 888) (OR: 0.76; 95% CI: 0.65-0.89) had a significantly lower chance of having TDI in the primary dentition. TDI was not associated with socioeconomic status (high vs low - OR: 0.77; 95% CI: 0.43-1.36; high vs medium - OR: 1.03; 95% CI: 0.72-1.48; medium vs low - OR: 0.70; 95% CI: 0.42-1.19), house ownership (owned vs rented - OR: 1.28; 95% CI: 0.98-1.66), mother's schooling (OR: 0.89; 95% CI: 0.74-1.08), or father's schooling (OR: 1.01; 95% CI: 0.62-2.74).
ConclusionThe scientific evidence demonstrates that socioeconomic indicators are not associated with TDI in the primary dentition. The evidence of an association between a low income and TDI is weak. In general, studies had low risk of bias. Further prospective cohort studies are needed to confirm this association.
