Infiltration resin versus microabrasion technique for repairing white spot lesions after orthodontics

doi:10.3969/j.issn.2095-4344.1739

Abstract

Abstract:

BACKGROUND: Infiltration resin technology is an emerging minimally invasive technique for repairing white spot lesions. There is a lack of comparative study on infiltration resin technology and other methods for repairing white spot lesions.

OBJECTIVE: To compare the aesthetic effect of infiltration resin and microabrasion in the restoration of post-orthodontic white spot lesions.

METHODS: Twenty-two patients with 88 teeth with white spot lesions after orthodontic treatment at Baodi Clinical College of Tianjin Medical University were recruited. A simple randomized and controlled design was used to allocate patients to resin infiltration and microabrasion groups (n=11/group). The patient’s satisfaction, clinical effect, area ratio of white spot lesions and treatment efficiency were compared between two groups, immediately, 1 week and 1, 3, 6 and 12 months after treatment. The study was approved by the Ethics Committee of Baodi Clinical College of Tianjin Medical University, approval number: TJBDYY-2015-26-R1.

RESULTS AND CONCLUSION: (1) The patient’s satisfaction in the resin infiltration group was significantly higher than that in the microabrasion group at different time points after treatment (P < 0.05). (2) Within 1 year after restoration, there were two teeth without change in the tooth white spot lesions in the infiltration resin group, and nine teeth without change in the tooth white spot lesions in the microabrasion group. The infiltration resin group had a higher success rate in aesthetic treatment of white spot lesions after orthodontics than the microabrasion group. (3) Compared with that before restoration, the area ratio of white spot lesions was decreased at different time points in both groups (P < 0.05), and the area ratio of white spot lesions in the infiltration resin group was lower than that in the microabrasion group at different time points (P < 0.05). (4) The treatment efficiency in the infiltration resin group was significantly higher than that in the microabrasion group at different time points (infiltration resin group: 71.31%, 83.95%, 85.08%, 89.65%, 89.11%, 88.90%; microabrasion group: 45.34%, 61.69%, 64.80%, 68.59%, 64.12%, 55.95%, P < 0.05). (5) Our results indicate that resin infiltration is more effective than microabrasion in the treatment of post-orthodontic white spot lesions, and the effect is stable within 12 months．
