To evaluate the effects of two different resin coating materials on the clinical performance of a conventional glass ionomer sealant.
Permanent first mandibular molars of 60 children aged 6-9 years were sealed with Fuji VII. In each child, G-Coat Plus coating agent was applied to molars on one side and Heliobond coating agent to molars on the opposite side of the mouth. Clinical evaluations were carried out at 1, 6, 12, 18 and 24 months after sealant and coating application.
At 1, 6, 12, 18 and 24 months after sealant and coating application, total sealant retention rates were 88%, 40%, 19%, 15% and 9% for molars coated with G-Coat Plus, and 93%, 47%, 17%, 15% and 7% for those coated with Heliobond. The differences between the two coating agents were not statistically significant (p>0.05). No incidence of caries was observed in either group during the two-year evaluation period.
Wilcoxon signed rank test was used to compare differences in retention rates and caries incidence by coating agent.
Although retention rates of Fuji VII were relatively low and similar for both resin coating agents tested, dental caries were not observed in either group during the 24-month study period. In children with a high risk of caries and partially erupted molars, the use of a glass ionomer sealant with a resin-based coating agent should be encouraged.
评估两种不同树脂涂层材料对传统玻璃离子封闭剂临床性能的影响。
选取60名6 - 9岁儿童的下颌第一恒磨牙，用富士VII进行封闭。在每个儿童口中，一侧磨牙使用G - Coat Plus涂层剂，另一侧磨牙使用Heliobond涂层剂。在封闭剂和涂层剂应用后的1、6、12、18和24个月进行临床评估。
在封闭剂和涂层剂应用后的1、6、12、18和24个月，使用G - Coat Plus涂层的磨牙封闭剂总保留率分别为88%、40%、19%、15%和9%，使用Heliobond涂层的磨牙封闭剂总保留率分别为93%、47%、17%、15%和7%。两种涂层剂之间的差异无统计学意义（p>0.05）。在两年的评估期内，两组均未观察到龋齿发生。
采用Wilcoxon符号秩检验比较不同涂层剂的保留率和龋齿发生率差异。
尽管富士VII的保留率相对较低，且两种测试树脂涂层剂的保留率相似，但在24个月的研究期内两组均未观察到龋齿。对于患龋风险高且磨牙部分萌出的儿童，应鼓励使用含树脂基涂层剂的玻璃离子封闭剂。
