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.
Children aged 7 to 12 years
Presence of bilateral molar-incisor hypomineralization (MIH) affecting first permanent molars
Need for restorative treatment in MIH-affected molars
Cooperative children with sufficient cognitive ability to complete functional assessments
Temporomandibular disorders or orofacial pain
Systemic diseases or regular medication use affecting mastication
History of orthodontic treatment or parafunctional habits
Craniofacial anomalies or developmental dental anomalies
Parallel
Glass Hybrid Restorative Treatment
Procedure/SurgeryRestorative treatment of MIH-affected molars using glass hybrid restorative material to evaluate changes in occlusal force distribution and chewing function.
Percentage of Occlusal Force Distribution Between Right and Left Sides
Percentage distribution of occlusal force between the right and left sides and chewing side assessed using a chewing gum test will be evaluated before and after restorative treatment in children with MIH using a digital occlusal analysis system.
