NCT06456619

Brief 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.

Study Arms (2)

Composite resin (Filtek Z250, 3M ESPE)

ACTIVE COMPARATOR

A pretreatment protocol including sodium hypochlorite and ortho-phosphoric acid was applied to the tooth surface. Then, the tooth was restored with a composite resin material (Filtek Z250, 3M ESPE). This protocol is a clinically approved way for restoring hypomineralized teeth.

Other: Tooth restoration

CAD-CAM supported (Cerasmart, GC Dental)

EXPERIMENTAL

The preparation was completed by making bevels on the enamel surfaces. Then, an intraoral impression was taken to sent to the laboratory for manufacturing CAD-CAM-supported restoration with a nanohybrid ceramic material (Cerasmart, GC Dental). CAD-CAM supported restorations can be done by using a lot of restorative blocks by milling them. In this study, we preferred using resin-based blocks (Cerasmart, GC Dental) to compare with the control group.

Other: Tooth restoration
