BACKGROUND
Fluoride releasing bonding agent were introduced to take care of white spot lesions. However, their clinically handling properties are less than ideal, deterring many practitioners. Reliance orthodontic products (Itacsa, I11) recently released an enamel sealant named Pro Seal to be used with bonding agents. Hu and Featherstone showed Pro Seal significantly decreased enamel demineralization. Hence, this study was undertaken to study the bond strength using Pro Seal.
MATERIALS AND METHODS
A total of 60 freshly extracted first premolars were collected and were randomly divided into two groups. Group 1 (Control group): Included 30 premolars where brackets bonded conventionally. Group 2 (Experimental group): Included 30 premolars where brackets bonded using of Pro Seal. Debonding procedures: All the teeth were mounted on a metallic mold. Debonding procedure was carried out for each tooth after a rest period of 5 min.
RESULTS
The results from this study show that the mean of bond strength in Group 1 was 24.9 N and in Group 2 was 21.1 N. There was statistical significant difference in bond strength when compared using t-test of Group 1 and Group 2. The study showed that Group 2 showed significantly less bond strength than Group 1. There was statistical significant difference in bond strength when compared using t-test, Group 2 showed significantly less bond strength than Group 1.
CONCLUSION
The study showed that use of Pro Seal provided adequate bond strength, but when compared with conventional bonding agents there was a significant decrease in bond strength.
背景
引入氟释放粘结剂来处理白斑病变。然而，它们的临床操作性能并不理想，这阻碍了许多从业者。信赖正畸产品公司（Itacsa，I11）最近推出了一种名为Pro Seal的釉质封闭剂，可与粘结剂一起使用。胡和费瑟斯通表明Pro Seal能显著减少牙釉质脱矿。因此，本研究旨在使用Pro Seal研究粘结强度。
材料与方法
总共收集了60颗新鲜拔除的第一前磨牙，并随机分为两组。第1组（对照组）：包括30颗采用传统方法粘结托槽的前磨牙。第2组（实验组）：包括30颗使用Pro Seal粘结托槽的前磨牙。脱粘结程序：将所有牙齿安装在金属模具上。在休息5分钟后对每颗牙齿进行脱粘结程序。
结果
本研究结果表明，第1组的粘结强度平均值为24.9 N，第2组为21.1 N。使用t检验比较第1组和第2组时，粘结强度存在统计学显著差异。研究表明，第2组的粘结强度明显低于第1组。使用t检验比较时，粘结强度存在统计学显著差异，第2组的粘结强度明显低于第1组。
结论
该研究表明，使用Pro Seal可提供足够的粘结强度，但与传统粘结剂相比，粘结强度有显著降低。
