Resumen
Background: Resin composite has been usually used for restoring primary teeth. Nevertheless, there is a lack of supporting clinical data regarding the survival of resin composite restorations and risk factors that may dictate the service time of the treatment in children. Aim: To evaluate the survival and factors associated with composite resin restoration failure in high caries risk children treated under risk-factor management clinical protocol for dental caries prior to restorative therapy. Design: A total of 230 restorations in primary teeth from records of 48 patients were included in the study. Restoration longevity, up to 3-year follow-up, was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (p<0.05). Results: Mean survival time was 2.7-year (95 %CI: 0.75-0.87). Restoration survival reached 82.5 % up to 3-year evaluation, with an overall annual failure rate of 6.2 %. The unadjusted model showed restorations performed in children with dmf-t greater than 10 had more restoration failure risk (HR 5.59, 95 % CI 1.03-30.34; p=0.04) However, this association lost significance in the adjusted analysis (p=0.08). Conclusions: Composite resin restorations in primary teeth presented satisfactory survival after 3-year follow-up.
