Influência da técnica de tratamento dentinário em restaurações Classe V: um ensaio clínico randomizado

Abstract

The aim of this study was to investigate the influence of the technique of removal or modification of the surface layer hypermineralized deposited on non-carious cervical lesions by evaluating parameters of aesthetic, functional and biological performance in longitudinal clinical bonded restorations with composite resin. Given the fact thesurface of hypermineralization LCNC influence retention and clinical performance of adhesive Class V restorations, we realized the need to investigate what would be the best and most conservative procedure to be adopted for the removal or modification of this surface layer hypermineralized through a clinical trial. This topic is of common interest to researchers, students, and especially dental professionals who perform daily adhesive restorative procedures. The randomization technique as for the removal or modification of the surface layer hypermineralized which was applied in each place by drawing lots. It is emphasized, also, that each operator performed the same number of restorative treatments, one of which was prepared following the protocol recommended by the manufacturer of the materials used, another increasing the etching time to 30 seconds and, finally, the third cavity would restored after performing a prophylaxis cavity with ultrasound probe applied for 30 seconds. The remaining steps were performed following the protocol recommended by the manufacturer of restorative materials used. Clinical assessments occurred in the following periods: one week (baseline) and 6 months after insertion of the restorations using parameters aesthetic, functional and biological. Data were tabulated and subjected to statistical analysis, considering 80% power and a significance level of 5%. No statistically significant difference was detected between groups when these characteristics were evaluated (p> .05). The study showed a good clinical performance in the three different treatments after 6 months dentinal used for evaluation.
