OBJECTIVE
The aim of this study was to determine the separate effects of dental sealants and fluoride varnish on dental caries in fissured and nonfissured surfaces of permanent first molars.
METHODS
A clinical trial was conducted with three groups of 6- to 8-year-old schoolchildren: a sealant group (n = 100), in which Delton was applied to first molars; a varnish group (n = 98), in which Duraphat was applied to first molars; and a control group (n = 116), which had no intervention as part of the study. Absolute and percent caries reductions were compared at 24 months.
RESULTS
Compared to the controls, sealants resulted in a 68 percent and 87 percent reduction on fissured and nonfissured surfaces, respectively. The corresponding figures for varnish were 38 percent and 66 percent.
CONCLUSION
Sealant and fluoride varnish are effective in preventing caries in both fissured and nonfissured surface.
目的
本研究旨在确定窝沟封闭剂和氟漆对恒牙第一磨牙窝沟及非窝沟表面龋齿的单独作用。
方法
对三组6至8岁学童进行了一项临床试验：窝沟封闭剂组（n = 100），对第一磨牙应用Delton；氟漆组（n = 98），对第一磨牙应用Duraphat；对照组（n = 116），作为研究的一部分不进行干预。在24个月时比较龋齿减少的绝对值和百分比。
结果
与对照组相比，窝沟封闭剂使窝沟表面和非窝沟表面的龋齿分别减少了68%和87%。氟漆的相应数字分别为38%和66%。
结论
窝沟封闭剂和氟漆在预防窝沟及非窝沟表面龋齿方面均有效。
