Abstract

Classification and resin infiltration treatment of MIH-related permanent anterior teeth are increasingly receiving attention nowadays. Objective: The study aims to evaluate the characteristics of these teeth; and to assess factors regarding treatment. Methods: A cross-sectional study was conducted using transilluminated and reflected light photographs, and the lesion was classified according to its color, size, type, heterogeneity and surface integrity. The data were analyzed using a chi-square test and multivariate logistic regression analysis to evaluate enamel craze lines (ECL), post-eruptive breakdown (PEB), and treatment procedures. Results: 73 teeth from 46 patients were included, in which 53 teeth had been treated. Size I showed the highest rate of PEB (66.67%). Females (OR = 20.39 (95%CI: 1.62 – 256.18)) and colored lesions (OR = 13.01 (95%CI: 1.82 – 93.13)) were associated with ECL/PEB. Microabrasion and etching cycles were inversely proportional and PEB required 4.33 etching cycles on average. A significant relationship was observed between surface integrity and composite fillings, between yellow/brown spot transformation and lesion color, sex and homogeneity. Conclusion: Lesion color, size, and sex are significant factors influencing ECL and PEB, while sex, surface integrity, lesion color, and homogeneity affect the treatment. Dental practitioners should consider these factors to provide appropriate treatment planning and consultation.

Abstract

Mild form of molar-incisor hypomineralization (MIH) on anterior teeth are posing great challenges to dental practitioners as it can have a huge aesthetic impact. In terms of deep MIH-related lesion below the healthy enamel, highly invasive methods for approaching the lesion body and removing the entire hypomineralized enamel using burs could lead to failures including aesthetic problems and even further tooth structure damage to the affected teeth. Case report: To resolve t his issue, we have proposed a modified resin infiltration technique based on the minimally invasive philosophy. In this study, we would like to report three specific cases about the use of the technique, which has the potential to restore the naturally aesthetic appearance for the anterior teeth while maintaining healthy tooth structure. Conclusion: Recovering the natural appearance of anterior teeth requires thorough attention to the aesthetics and integrity of the affected teeth. The proposed modified resin infiltration technique has been illustrated to bring back the natural morphology and maximally protect the healthy structure to ensure a long-term treatment outcome. The technique should be implemented to a significant degree for the long-term improvement in the oral health of pediatric patients in Vietnam and around the world.
