This shallow cavity preparation for the restoration of incipient proximal caries lesions was easy to perform and well tolerated by the patients, often without local anesthesia. Both parents and children were pleased with the appearance of the restoration. The radiopaque version tested did not differ from the commercial composite and had definite advantages in the clinical evaluation. Changes in the anatomic form were not a salient feature in this study. Failures are thought to be related to difficulties in the clinical manipulation of the material, but also to the cavity design and the omission of the intermediate bonding resin. The fact that, after two years, one-third of the restorations were still rated as excellent, and many seems to remain unchanged through the third year, shows that a favorable circumstances the composite resin functions well as a restorative material in Class II cavities in primary molars.
这种用于早期邻面龋损修复的浅洞制备操作简便，患者耐受性良好，通常无需局部麻醉。家长和孩子对修复体的外观都很满意。所测试的不透射线版本与市售复合材料并无差异，且在临床评估中具有明显优势。解剖形态的改变并非本研究的显著特征。修复失败被认为与材料临床操作困难有关，但也与洞型设计以及中间粘结树脂的省略有关。两年后仍有三分之一的修复体被评为优秀，且许多修复体在第三年似乎仍无变化，这一事实表明，在有利条件下，复合树脂作为乳牙Ⅱ类洞修复材料功能良好。
