Molar incisor hypomineralization (MIH) is a condition which involves enamel hypomineralization of one to four first permanent molars with or without permanent incisors. Affected permanent incisors present with demarcated enamel opacities which cause esthetic and psychological problems to patients with MIH. Microabrasion and etch-bleach surface treatment can provide easier, conservative, and biologically driven treatment approach compared to macroabrasion prior to prolonged resin infiltration for treating enamel opacities in incisors of MIH patients.
The aim of this study is to evaluate the effect of microabrasion and etch-bleach surface treatment compared to macroabrasion prior to prolonged resin infiltration on esthetic appearance of permanent incisors affected with demarcated enamel opacities in MIH patients.
