Abstract:
OBJECTIVETo evaluate the effect of infiltration resin on masking white spot lesions by assessing the change in the white spot area.
METHODSSeventy-four maxillary anterior teeth with post-orthodontic decalcification teeth were investigated in this study. All teeth were treated with infiltration resin according to manufacturer recommendation. Standardized digital images were taken before, immediately after, and one week after treatment. The results were classified into three groups: com-pletely masked, partially masked and unchanged. The images of partially masked teeth were analyzed using an image analysis software. The size of the white spot lesion (W) and the whole-tooth facial surface (T) were measured, and the W:Tratio (%) was calculated. Statistical evaluation of the lesions was performed using Kruskal-Wallis and Mann-Whitney tests.
RESULTSAmong the 74 teeth, 20 (27%) teeth were classified as completely masked and 54 (73%) teeth were classified as partially masked; no tooth was unchanged. The W:T ratio significantly decreased from 39.28% before treatment to 9.46% after treatment (P < 0.05).
CONCLUSIONResin infiltration is an effective treatment for masking white spot lesion. However, the masking effect depends on the lesion depth and activity.
