In vivo comparative evaluation of esthetics after microabrasion and microabrasion followed by casein phosphopeptide-amorphous calcium fluoride phosphate on molar incisor hypomineralization-affected incisors

Background: Molar incisor hypomineralization (MIH) is an esthetic setback for the patient as well as for the dentist, treatment options for MIH includes minimally invasive techniques like microabrasion which has a limited literature of its effect. Furthermore, the effect of remineralizing such as casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) agent on MIH-affected teeth is minimally studied. Aim: Comparative evaluation of the esthetic after microabrasion and microabrasion followed by Tooth Mousse Plus on hypomineralized incisors of MIH-affected patients. Settings and Design: The study was a randomized clinical trial. Materials and Methods: The study comprised Grade I MIH patients in the age strata of 7-16 years having lesions on incisors. As per inclusion criteria, 46 lesions were divided into two groups of microabrasion and microabrasion followed by CPP-amorphous calcium fluoride phosphate (ACFP). Photographs were obtained before treatment, just after treatment, and 6 months after treatment. The photographic evaluation was done using the CIE L*a*b* scoring method. Statistical Analysis Used: ANOVA and posthoc Tukey's test were applied to compare the difference in lightness Delta L and total color change Delta E of these two groups. Results: In microabrasion group, the overall change in Delta L of white tooth discoloration came -0.9 standard deviation (SD) 7.3. In microabrasion followed by CPP-ACFP group, statistically significant difference was found between both these groups with P value of P <= 0.001. Conclusions: Microabrasion followed by the remineralizing agent can improve the esthetics of white tooth discoloration with time.
