The aim of this study was to evaluate the effect of different remineralization agents-Proshield Fluoride Varnish (FV), GC MI Varnish (MI), and ROCS Medical Mineral Gel (ROCS MMG)-on the shear bond strength (SBS) of orthodontic brackets after application at various time intervals.
A total of 120 human premolar teeth were divided into 10 groups (n = 12). The experimental groups received different remineralization agents (FV, MI, ROCS MMG) at time intervals of 1, 15, and 30 days, while the control group received no application. The enamel surfaces were etched, and metal orthodontic brackets were bonded using a light-cured composite adhesive. SBS was measured using a universal testing machine, and adhesive remnant index (ARI) scores were assessed after bracket debonding.
No statistically significant differences were observed in SBS among all experimental groups and the control group (P = 0.307). SBS values for the FV, MI, and ROCS MMG groups did not differ significantly at the 1, 15, or 30-day intervals. ARI scores also showed no significant differences between groups (P = 0.370).
The application of Proshield Fluoride Varnish, GC MI Varnish, and ROCS Medical Mineral Gel at different time intervals did not affect the shear bond strength of orthodontic brackets. These remineralization agents can be safely used to prevent white spot lesions and caries before orthodontic treatment at time intervals of 1, 15, and 30 days without compromising bond strength.
Proshield FV, GC MI Varnish, and ROCS MMG safely prevent white spot lesions and caries without affecting bracket bond strength.
本研究旨在评估不同再矿化剂——Proshield氟化物清漆（FV）、GC MI清漆（MI）和ROCS医用矿物凝胶（ROCS MMG）——在不同时间间隔应用后对正畸托槽剪切粘结强度（SBS）的影响。
总共120颗人前磨牙被分为10组（每组n = 12）。实验组在1天、15天和30天的时间间隔接受不同的再矿化剂（FV、MI、ROCS MMG），而对照组不进行任何处理。对牙釉质表面进行酸蚀，并用光固化复合粘结剂粘结金属正畸托槽。使用万能试验机测量SBS，并在托槽脱粘后评估粘结剂残留指数（ARI）得分。
所有实验组和对照组之间的SBS没有观察到统计学上的显著差异（P = 0.3
