Context: One of the challenges associated with the use of composite resin as a posterior restorative material is to create an intact and optimal proximal area.
Aim: Aim of this in vivo study is to evaluate the proximal contacts in class II cavities restored with composite using V3 sectional matrix and precontoured self-adhesive matrix.
Settings and Design: After determining the power (0.84) of the study, 40 patients who fulfill the inclusion criteria were divided into two groups.
Methods and Material: In Group A Palodent V3 sectional matrix and in Group B precontoured self-adhesive matrix were used and evaluated for two outcomes, the primary outcome was proximal contact tightness, and the secondary outcome was proximal contour and overhangs of the restoration.
Statistical Analysis: IBM SPSS (Version 21.0) software was used. Chi-square test and Spearman's rank correlation test were performed. Statistical significance was set at P value equal to or less than 0.05.
Results: There was no statistically significant difference in contact tightness, contours, and overhangs between the two groups.
Conclusions: Within the limitations of the study. • Both V3 sectional matrix and precontoured self-adhesive matrix showed similar performance in terms of proximal contact tightness, proximal contour, and overhangs of the restoration. • However, a well-designed randomized controlled study with long-term follow-up must be performed to give valid evidence.
