Masticatory Performance

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.

The purpose of this experiment is to combine research on masticatory efficiency with the reconstructive expertise of the prosthodontics clinic, focusing on implant-supported fixed dentures as the contemporary gold standard for reconstruction. The goal is to investigate the impact of such prosthetic reconstructions on masticatory efficiency. We will invite patients who have lost their second molar and have undergone single-implant-supported fixed denture reconstruction at the Prosthodontics Department of National Taiwan University Hospital to participate in masticatory function tests. The tests will use a new and relatively simple chewing gum, with the aim of enhancing patients\' masticatory function through implant reconstruction in a clinical setting, thereby improving patient well-being and understanding of dental implants. On the research side, the study aims to provide guidance for strategies in the reconstruction of masticatory function.
