Evaluation Direct and Indirect Composite Restoration in Hypomineralization Molars.

Clinical Randomized Controlled Trial To Compare Direct and Indirect Composite Restoration in Children With Molar Incisor Hypomineralization Patients (MIH)

The aim of this study is to evaluate the effectiveness of direct and Indirect Composite Restoration in Children With Molar Incisor Hypomineralization Patients (MIH) and following up after 3 , 6 , 12 months (Clinically):

Group A ( Control group ): Hypomineralization molars were restored by direct composite.

Group B ( Experimental group ): Hypomineralization molars were restored by indirect composite.

Pediatric dentists face a high prevalence of MIH ranging from 3 to 40%, so it is relatively common condition that would cause treatment challenges due to severe sensitivity, breakdown of the occlusal surface, difficulty anesthesia and relatively high failure of restorations as a result of marginal breakdown of restorations.

There are many treatment options available to restore these teeth. In mild and moderate cases, they are restored using direct composite resin. In cases where teeth are severely affected, the treatment is more complicated, including stainless steel crowns and different types of full or partial indirect crowns.

Direct composite resin restorations are the treatment option in the majority of clinical cases, but in severe cases, the results of treatment are often unsatisfactory.

Indirect composite restorations are an aesthetic alternative to cast metal inlays and stainless steel crowns with minimal microleakage.
