Treatment of Post-Orthodontic whitespot Lesions By Resin Infiltration

Objective: The aim of the study is to evaluate the effectiveness of resin infiltration in the treatment of postorthodontic white spot lesions. Materials and Methods: This was clinical trial. 9 subjects with mean age 18.25 with multiple white spot lesions in incisors and premolars area were included in this study. Lesions (44 lesions) were treated by ICON-Infiltrant with assessment of the lesions before, after application, after 3 months and after 6 months. Visual assessment of white spot lesions was done using International Caries Detection and Assessment System (ICDAS-II) for scoring dental caries. The scoring criteria according to the ICDAS-II system for Coronal Smooth Surface Caries are graded from 0 to 6. Patient satisfaction score was recorded according to patient’s own selection for each quadrant before, after intervention, after 3 months and after 6 months follow up. Results: there was a statistically significant decrease in caries scores at T1. From T1 to T2 as well as from T2 to T3; there was no statistically significant change in mean caries scores. However, T1, T2 and T3 scores showed statistically significantly lower mean scores than T0. Concerning the patient satisfaction there was a statistically significant increase in satisfaction scores at T1. From T1 to T2 as well as from T2 to T3; there was no statistically significant change in mean satisfaction scores. However, T1, T2 and T3 scores showed statistically significantly higher mean scores than T0. Conclusions: Icon resin infiltration improved esthetics of demineralized lesions. Icon resin infiltration improves the esthetic appearance of demineralized teeth significantly immediately after application. Esthetic outcomes of icon resin infiltration showed adequate stability for 6 months. -------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 23 -10-2017 Date of acceptance: 04-11-2017 --------------------------------------------------------------------------------------------------------------------------
