Summary

Aim: This randomized controlled clinical study aimed to compare direct composite resin restorations and Computer Aided Design-Computer Aided Manufacturing (CAD-CAM) supported inlay or onlay restorations in young permanent molar teeth with hypomineralization. The main questions aim to answer are: * The clinical success rate of CAD-CAM supported restorations * The highest clinical success rate for restoring hypomineralized teeth. Materials and method: Children aged 6-14 years old without any systemic conditions with 32 first and second hypomineralized permanent molar teeth were included in the study. Patients were randomly distributed into 2 groups as direct composite resin restorations and CAD-CAM supported inlay or onlay restorations. All restored teeth were evaluated clinically and radiographically for 24-months. Statistical significance was accepted as p\<0.05.

Detailed description

After randomization and local anesthesia administration, caries removal and preparation were completed under rubber-dam isolation. After preparation, 60 seconds of orthophosphoric acid, 60 seconds of 5% sodium hypochlorite and 30 seconds of orthophosphoric acid steps were applied before bonding agent and composite resin restorations. On the other hand, the preparation was completed by making a bevel on the enamel surfaces and a nanohybrid ceramic material used for the manufacturing CAD-CAM supported inlay or onlay restorations.
