PURPOSE
To compare the retention of a multi-use bonding agent (OptiBond) to a conventional sealant (Delton) used as pit and fissure sealants.
MATERIALS AND METHODS
An informed consent was obtained from 38 subjects aged 11-17 yrs. Delton, a self-cured sealant, was applied to 86 teeth, and OptiBond, a dual-cure glass filled adhesive, was applied to 85 teeth, under cotton roll isolation and saliva ejector. Each subject received both sealing materials, randomly assigned to the sides of the mouth. The sealed teeth were followed up to 30 months. Clinical evaluation was performed by two examiners and the retention was classified as failure or success.
RESULTS
Statistical analysis based on a stratified Cox proportional hazards regression model indicated that OptiBond had better clinical performance than Delton (P < 0.001).
目的
比较一种多用途粘结剂（OptiBond）与用作窝沟封闭剂的传统封闭剂（Delton）的保留率。
材料与方法
从38名年龄在11至17岁的受试者处获得知情同意书。在棉卷隔离和唾液抽吸器辅助下，将自固化封闭剂Delton应用于86颗牙齿，将双固化玻璃填充粘合剂OptiBond应用于85颗牙齿。每个受试者均接受两种封闭材料，随机分配至口腔两侧。对封闭的牙齿进行长达30个月的随访。由两名检查者进行临床评估，保留情况分为失败或成功。
结果
基于分层Cox比例风险回归模型的统计分析表明，OptiBond的临床性能优于Delton（P < 0.001）。
