Clinical performance of short fiber-reinforced and indirect resin composites in class I and class II restorations: A three-year randomized clinical trial.

ABSTRACT:

Objective

This prospective randomized clinical trial was designed to evaluate and compare the three-year clinical performance of short fiber-reinforced composite (SFRC) and indirect laboratory (lab) composite with that of a microhybrid resin composite placed in Class I and Class II cavities, with marginal adaptation defined as the primary outcome.

Materials and methods

Thirty-three participants, each exhibiting 3 posterior carious teeth (Class I or II, ICDAS 4 or 5) under stable occlusion, were enrolled in this study. A total of 99 restorations (33 for each material) were placed as follows: SFRC (everX Posterior), indirect lab composite (SR Nexco), and microhybrid resin composite (G-aenial Posterior). Clinical assessments were conducted at baseline (1 week), 6 months, 1, 2,
