“Tiempo operatorio y análisis del gap interno provocado por la microfiltración de las resinas convencionales vs Bulk Fill: un estudio in vitro”

Abstract

Objective: To determine the operative time and the internal restoration gap at the restoration-tooth interface using the oblique incremental technique for conventional resins and the monobloc technique for Bulk fill resin. Materials and Methods: This experimental in vitro study determined the restoration time of 40-third molars with two conventional resins and two Bulk fill resins, a sample that, after a thermocycling and cutting process, permitted microscopic analysis of the internal gap between restoration-tooth at the cavity floor, mesial and distal levels. Results: Bulk fill resins have a smaller inner gap (63.31 µm) than conventional resins (333.14 µm). The monobloc technique obtained the best results in restoration time (p<0.05). Conclusions: The Tetric N-Ceram Bulk Fill resin performed better than conventional resins with the internal gap of the cavity floor, and the monobloc technique showed less clinical restoration time.
