The purpose of this study was to evaluate and compare the retention rates and development of caries in permanent molars in children sealed with moisture-tolerant, resin-based (Embrace WetBond), and conventional resin-based (Helioseal) sealant over a period of one year.
This was a double blind, split-mouth, randomized controlled trial among six- to nine-year-olds. Sixty-eight permanent mandibular first molars in 34 children were randomly assigned to be sealed with Embrace WetBond or Helioseal sealant.
The final sample was 32 children with 64 teeth. At 12 months, 23 of 32 (72 percent) sealants were completely retained in Embrace WetBond, whereas only 16 of 32 (50 percent) were retained in the Helioseal group. There was a statistically significant difference in retention rates of Embrace WetBond and Helioseal sealants at 12 months (P<.05). At 12 months follow-up, only two teeth developed caries in Embrace WetBond; in the Helioseal group, five teeth developed caries (two initial and three enamel caries).
Embrace WetBond was superior to Helioseal sealant, as Embrace exhibited higher retention and lower caries scores. Embrace WetBond can be preferred over conventional resin-based sealants for community and outreach sealant programs where use of rubber dam for moisture control is difficult to practice.
本研究旨在评估和比较在一年时间内，使用耐湿树脂基（Embrace WetBond）密封剂和传统树脂基（Helioseal）密封剂对儿童恒牙磨牙进行窝沟封闭后的保留率和龋齿发展情况。
这是一项针对6至9岁儿童的双盲、半口、随机对照试验。34名儿童的68颗下颌第一恒磨牙被随机分配使用Embrace WetBond或Helioseal密封剂进行窝沟封闭。
最终样本为32名儿童的64颗牙齿。12个月时，Embrace WetBond组32颗密封剂中有23颗（72%）完全保留，而Helioseal组32颗中只有16颗（50%）保留。12个月时，Embrace WetBond和Helioseal密封剂的保留率存在统计学显著差异（P<0.05）。12个月随访时，Embrace WetBond组只有两颗牙齿发生龋齿；Helioseal组有五颗牙齿发生龋齿（两颗初期龋和三颗釉质龋）。
Embrace WetBond优于Helioseal密封剂，因为Embrace表现出更高的保留率和更低的龋齿评分。在社区和外展窝沟封闭项目中，如果难以使用橡皮障控制湿度，Embrace WetBond可能比传统树脂基密封剂更受青睐。
