Summary

Introduction:

Resin-based composites (RBCs) have become the gold standard in restorative dentistry due to their superior aesthetics, adhesion, and minimally invasive application. However, wear remains a critical drawback, compromising their longevity and clinical performance. Various techniques have been suggested to measure the clinical performance of (RBCs). Recent advancements in digital dentistry, such as intraoral scanning, offer a more precise and efficient approach for quantitative wear assessment.

Aim:

This study aims to evaluate wear resistance and bioactivity of self cured bioactive resin composite vs nanhybrid resin composite.

Methodology:

Twelve healthy patients with 24 carious molar teeth will be selected where each patient should have two oclusso- mesial cavities. Standardized oclusso- mesial cavities will be prepared for all the selected teeth, for each patient the first tooth will be restored with conventional nanohybrid RBC (M1). Meanwhile, the second tooth will be restored by self-cure bioactive RBC (M2). Then, wear resistance will be evaluated by intraoral scanner immediately after restoration (T0), six months later (T1), after 12 months (T2), 18 months (T3) and 24 months (T4). Software analysis will be done by superimposing the 3D digital impression and evaluate the restoration wear by calculating the 3D volume loss.

Also, bioactivity of the restoration will be measured by measuring the mineral density beneath the restoration. Digital radiographic images will be taken for the restoration by parallel technique and grey scale of the pixels under restoration will be measured by software immediately after restoration (D0), one month later (D1) and after 3 months (D2).
