NCT07589179

Brief Summary

This study aims to evaluate right-left chewing balance and masticatory function in children with Molar-Incisor Hypomineralization (MIH) before and after restorative treatment. MIH is a developmental enamel defect that may cause tooth sensitivity, discomfort during chewing, and functional asymmetry. Children aged 7 to 12 years with bilateral MIH affecting the first permanent molars will receive glass hybrid restorative treatment. Right-left occlusal force distribution will be assessed using a digital occlusal analysis system. In addition, chewing side preference and chewing balance will be evaluated using a standardized chewing gum protocol. These two assessment methods will be used together to provide complementary information about masticatory function. Measurements will be performed before treatment and during follow-up visits after treatment. The findings obtained from children with MIH will also be compared with healthy children without MIH. The study aims to determine whether restorative treatment improves chewing balance and functional oral performance in children with MIH.

Outcome Measures

Primary Outcomes (1)

  • Right-Left Occlusal Force Distribution

    Occlusal force distribution between the right and left sides will be evaluated using a digital occlusal analysis system before and after restorative treatment in children with MIH.

    Baseline and 3 months after restorative treatment

Study Arms (2)

MIH Restorative Treatment Group

EXPERIMENTAL

Children with molar-incisor hypomineralization (MIH) will receive glass hybrid restorative treatment. Occlusal force distribution and chewing function will be evaluated before and after treatment using digital occlusal analysis and a chewing gum protocol.

Procedure: Glass Hybrid Restorative Treatment

Healthy Control Group

NO INTERVENTION

Healthy children without MIH will undergo occlusal force distribution and chewing function assessments for comparison with the MIH group. No restorative intervention will be performed.

Interventions

Restorative treatment of MIH-affected molars using glass hybrid restorative material to evaluate changes in occlusal force distribution and chewing function.
