Bonding before sealant application enhances retention on saliva-contaminated sound teeth; however, there are few studies of bonding's efficacy on sealant retention on occlusal caries.
To evaluate a bonding agent's efficacy on sealant retention on occlusal caries and caries transition.
One hundred twenty pairs of first permanent molars with occlusal caries (ICDAS 2-4) from 98 children aged 7.3-9.9 years were included. One molar was randomly selected to use bonding (Adper™ Single Bond 2, 3M ESPE) applied before sealant application (Helioseal clear, Ivoclar Vivadent). Bonding was not used on the contralateral tooth. Retention was determined using Simonsen's criteria; caries transition was evaluated using ICDAS scores, DIAGNOdent values, and bitewings at baseline, 6, 12, and 24 months. Data were analyzed with McNemar's and Fisher's exact tests.
Bonding agent use significantly increased sealant retention rates (P < .001). Bonded (B) sealants had a higher retention rate (83.3%) than non-bonded (NB) sealants (53.7%). The difference in the caries-transition rate was not significant between the groups (P > .05). Three teeth (1.4%; NB:B = 2:1) were restored due to radiographic dentin-caries progression.
Using a bonding agent before applying sealant on permanent molar occlusal caries (ICDAS 2-4) significantly enhanced sealant retention. Caries progression was rarely detected at the 24-month follow-up.
在使用封闭剂之前进行粘结可以增强对唾液污染的健康牙齿的粘结保持力；然而，关于粘结剂在封闭剂对窝沟龋的保持力方面的效果的研究较少。
评估粘结剂对窝沟龋和龋病进展的封闭剂保持力的效果。
本研究纳入了 98 名 7.3-9.9 岁儿童的 120 对第一恒磨牙，这些磨牙均有窝沟龋（ICDAS 2-4）。每颗磨牙随机选择使用粘结剂（Adper™Single Bond 2，3M ESPE），在使用封闭剂（Helioseal clear，Ivoclar Vivadent）之前进行粘结。对侧牙齿不使用粘结剂。使用 Simonsen 标准评估保留率；使用 ICDAS 评分、DIAGNOdent 值和基线、6、12 和 24 个月的咬翼片评估龋病进展。采用 McNemar 检验和 Fisher 确切概率法进行数据分析。
粘结剂的使用显著提高了封闭剂的保留率（P<.001）。粘结封闭剂（B）的保留率（83.3%）高于非粘结封闭剂（NB）（53.7%）（P<.001）。两组间的龋病进展率差异无统计学意义（P>.05）。有 3 颗牙（1.4%；NB:B=2:1）因影像学牙本质龋进展而需要修复。
在恒牙窝沟龋（ICDAS 2-4）上使用粘结剂之前应用封闭剂显著提高了封闭剂的保留率。在 24 个月的随访中很少发现龋病进展。
