Clinical studies comparing retention rates of pit and fissure sealants placed under Isolite, rubber dam, and cotton roll combined have not been conducted until now.
To evaluate the retention rate of pit and fissure sealants (PFS) placed under three different isolation techniques (Isolite system [IS], rubber dam isolation [RDI], and cotton roll isolation [CRI]).
One hundred and forty-four teeth from 48 children aged 6-15 years attending paediatric dental clinics at King Saud University in Saudi Arabia were randomized to receive three PFS using three isolation techniques. The children that met the inclusion criteria were randomized by a simple block random allocation method. All PFS were placed by an operator and evaluated by a blinded evaluator. The evaluation scores were recorded at baseline and followed up over a period of 12-22 months.
The children's mean age was 8.58 ± 1.93 years. Seven patients were lost to follow-up. A total of 123 teeth were clinically evaluated; of these teeth, 22% had completely retained sealants, whereas approximately 66% had a partial loss of sealants, and approximately 12% had a complete loss of sealants. There were, however, no significant differences between the three isolation techniques on the retention rate of pit and fissure sealant.
The types of isolation had no impact on the retention rate of pit and fissure sealant.
迄今为止，尚未开展过比较在光固化灯、橡皮障和棉卷联合隔离下放置的窝沟封闭剂保留率的临床研究。
评估在三种不同隔离技术（光固化灯系统[IS]、橡皮障隔离[RDI]和棉卷隔离[CRI]）下放置的窝沟封闭剂（PFS）的保留率。
从沙特阿拉伯国王沙特大学儿科牙科诊所就诊的48名6至15岁儿童的144颗牙齿中随机选取，使用三种隔离技术接受三种窝沟封闭剂。符合纳入标准的儿童通过简单的区组随机分配方法进行随机分组。所有窝沟封闭剂均由一名操作人员放置，并由一名盲法评估人员进行评估。在基线时记录评估分数，并随访12至22个月。
儿童的平均年龄为8.58±1.93岁。7名患者失访。共对123颗牙齿进行了临床评估；在这些牙齿中，22%的牙齿封闭剂完全保留，约66%的牙齿封闭剂部分脱落，约12%的牙齿封闭剂完全脱落。然而，三种隔离技术在窝沟封闭剂保留率方面没有显著差异。
隔离类型对窝沟封闭剂的保留率没有影响。
