A clinical evaluation of an experimental resin sealant (ICI 209085) was made by comparing it with a previously investigated and well recognized material (Light Cured Tinted Delton). The two materials were bilaterally placed in 117 pairs of teeth (48 premolars and 69 molars) in 60 children aged 6-14 years. The children were re-examined after 6, 12 and 24 months. The overall rates of full retention were 97.4% in teeth sealed with the experimental sealant and 96.6% in those sealed with the control sealant, while the corresponding figures for partial retention were 2.6% and 3.4%. From none of the teeth were the sealants totally lost. No carious lesions developed in the sealed fissures during the trial. It is concluded that the experimental sealant is comparable with the control sealant with respect to retention and caries prevention.
通过将一种实验性树脂封闭剂（ICI 209085）与一种先前已研究且广为人知的材料（光固化彩色德尔顿）进行比较，对该实验性树脂封闭剂进行了临床评估。这两种材料双侧放置在60名6至14岁儿童的117对牙齿（48颗前磨牙和69颗磨牙）中。在6个月、12个月和24个月后对这些儿童进行了复查。用实验性封闭剂封闭的牙齿的完全保留总体率为97.4%，用对照封闭剂封闭的牙齿的相应总体率为96.6%，而部分保留的相应数字分别为2.6%和3.4%。没有一颗牙齿的封闭剂完全脱落。在试验期间，封闭裂隙中未出现龋损。得出的结论是，在保留率和预防龋齿方面，实验性封闭剂与对照封闭剂相当。
