Minimally interventive restorative care of teeth with molar incisor hypomineralization and open apex—A 24-month longitudinal study

Abstract

Aim: To assess the efficacy of treatment using a minimally invasive approach (selective removal of carious tissue, restoration and preventive strategies) in immature permanent molars with MIH. Design: A total of 281 patients, aged 6-8 years, with carious lesions (ICDAS 5-6), severe MIH, and incomplete root formation (one tooth/patient) were included. After clinical and radiographic examinations, selective carious tissue removal was performed, and the teeth received interim restoration for 6 months and were then restored with composite resin. Clinical and radiographic follow-up was undertaken, 6, 12, 18, and 24 months. A protocol of preventive oral care measures was established and repeated a..
