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 ΔL and total color change ΔE of these two groups.

Results: In microabrasion group, the overall change in ΔL 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.
