Abstract

OBJECTIVE

This study evaluated the effectiveness of sealant retention and caries prevention with and without primer and bond below the fissure sealant among Kuwaiti schoolchildren.

SUBJECTS AND METHODS

This clinical trial used fissure sealant that was applied to four sound first permanent molars on 78 children. All the teeth were cleaned with pumice and rubber cups, isolated with rubber dams, and etched for 20 s. In a split-mouth study design, for the test teeth (n = 156), primer and bond (3M Scotchbond Multi-Purpose Plus System primer and bond) were applied below the sealant, and for the control teeth (n = 156), only sealant (Delton Plus) was applied. The number of tooth surfaces included was 480. Due to loss to follow-up, only 60 children were evaluated at 5 years for sealant retention and caries. The evaluation criteria were: completely retained sealant, complete or partial sealant retention, and caries.

RESULTS

In teeth sealed with primer and bond, 47 (19.6%) tooth surfaces had completely retained sealant, 60 (9.2%) teeth had partially retained sealant, while in 51 (21.3%) caries was prevented and 120 (50%) tooth surfaces were carious or filled. In teeth sealed without primer and bond, 25% (60 tooth surfaces) had completely retained sealant, 6% (14 teeth surfaces) had partially retained sealant, 26% (54 teeth surfaces) showed caries prevention, and 49.6% (119 tooth surfaces) were carious or filled. There was no difference between teeth sealed with primer and bond (120 teeth) and teeth sealed without primer and bond (120 teeth) in completely retained sealant (p = 0.15), complete or partial sealant retention (p = 0.6), caries prevented (p = 0.37), and caries (p = 0.93).

CONCLUSION

Caries prevention was not enhanced in teeth sealed with primer and bond sealant compared with those sealed with sealant alone.

摘要

目的

本研究评估了在科威特学童中使用密封剂保留和防龋效果，同时评估了在密封剂下方使用底漆和粘结剂与不使用底漆和粘结剂的效果。

受试者和方法

本临床试验使用了在 78 名儿童的四颗健康的第一恒磨牙上应用的窝沟封闭剂。所有牙齿均用浮石和橡胶杯清洁，用橡皮障隔离，酸蚀 20 秒。在分口研究设计中，对于测试牙（n = 156），在密封剂下方使用底漆和粘结剂（3M Scotchbond Multi-Purpose Plus System 底漆和粘结剂），而对于对照牙（n = 156），仅应用密封剂（Delton Plus）。纳入的牙面数为 480。由于失访，只有 60 名儿童在 5 年时接受了密封保留和龋齿的评估。评估标准为：完全保留的密封剂、完全或部分保留的密封剂和龋齿。

结果

在使用底漆和粘结剂密封的牙齿中，47 个（19.6%）牙面具有完全保留的密封剂，60 个（9.2%）牙齿具有部分保留的密封剂，而在 51 个（21.3%）牙齿中预防了龋齿，在 120 个（50%）牙面中发生了龋齿或填充。在未使用底漆和粘结剂密封的牙齿中，25%（60 个牙面）具有完全保留的密封剂，6%（14 个牙面）具有部分保留的密封剂，26%（54 个牙面）显示出预防龋齿的效果，而 49.6%（119 个牙面）发生了龋齿或填充。使用底漆和粘结剂密封的牙齿（120 颗）与未使用底漆和粘结剂密封的牙齿（120 颗）在完全保留的密封剂方面没有差异（p = 0.15），完全或部分保留的密封剂（p = 0.6），预防龋齿（p = 0.37）和龋齿（p = 0.93）。
