A study was performed to determine the success of a conservative cavity preparation using the principle of sealing for prevention rather than cavity extension for prevention. A total of 332 restorations were placed in 240 teeth of 110 subjects, aged 6 to 14, with a mean age of 8 years. After 4 years, 205 restorations were examined. Caries appeared in 13 teeth and sealant wear occurred in 14 restorations. Complete sealant loss was observed in eight restorations and partial loss in 38, leaving 156 restorations with complete retention of the sealant. These preliminary results show that conservative cavity preparation with sealing for prevention is a successful technique that conserves valuable tooth structure.
开展了一项研究，以确定采用预防性封闭原则而非预防性扩展洞形的保守性窝洞预备的成功率。共有110名年龄在6至14岁（平均年龄8岁）的受试者的240颗牙齿上进行了332次修复。4年后，检查了205次修复情况。13颗牙齿出现龋齿，14次修复出现封闭剂磨损。观察到8次修复的封闭剂完全脱落，38次部分脱落，156次修复的封闭剂完全保留。这些初步结果表明，采用预防性封闭的保守性窝洞预备是一种成功的技术，可保留宝贵的牙体组织。
