Efficacy of microabrasion and resin infiltration techniques for masking of fluorotic white spot lesions: A randomized clinical study.

Aim: The aim of the study was to compare the esthetic treatment outcome and quantification of tooth color changes using microabrasion and resin infiltration techniques of fluorotic white spot lesions (WSLs).

Subjects And Methods: Sixty-six teeth with fluorotic small opaque white areas involving 25%-50% (very mild/mild fluorosis) of the surface were randomly assigned into two groups for microabrasion and resin infiltration techniques. To quantify tooth color changes, depicted by Delta E (DE), photographic analysis was performed using Adobe Photoshop CS5 Extended version by measuring Commission Internationale de l'Eclairage L*a*b* values of each tooth at two points, i.
