ĐẶC ĐIỂM TỔN THƯƠNG MIH VỚI ÁNH SÁNG XUYÊN THẤU

Abstract

Objective: The aim is to describe the characteristics of MIH lesions using transillumination light in a group of children with teeth affected by MIH in Sa Dec City, Dong Thap Province. Materials and methods: This study is a descriptive cross-sectional study involving 35 children affected by MIH. Results: 35 patients contributed 49 teeth to the study. Of the 35 children, 31 had incisors with mild MIH, while 4 had severe MIH only, without any cases of simultaneous mild and severe MIH. In terms of lesion type, 25 teeth were classified as type 1 (51.02%), 13 teeth as type 2 (26.53%), and 11 teeth as type 3 (22.45%). The most commonly affected teeth were the upper central incisors, accounting for 28 teeth (57.14%). Conclusion: The use of transillumination light is valuable in supporting diagnosis and providing treatment prognosis. The classification based on transillumination light usage can help predict the number of teeth at risk of post-eruptive enamel breakdown (PEB). The upper central incisors are frequently affected, with type 1 lesions being the most prevalent among the three lesion types when examined with transillumination light.
