窝沟封闭剂(通常为不含填料的树脂)是一种放置于点隙裂沟中的防龋材料。英国儿童牙医学会继续提倡将使用窝沟封闭剂作为一种防龋手段。最近15年的研究表明,封闭剂是安全有效的。在进行常规牙科检查时,要注意封闭剂的完整性,若有缺陷应及时重新封闭。做到这一些,就可能获得近100％的预防窝沟龋的效果。 应取消过去关于只在牙齿萌出后2年内进行封闭的建议。对于那些易患龋的窝沟可以不考虑该牙已萌出的时间,一律做窝沟封闭。
Pit and fissure sealant (usually a filler-free resin) is an anti-caries material that is placed in a crevice gap. The British Children's Dental Association continues to advocate the use of pit and fissure sealants as an anti-carious tool. Recent 15 years of research have shown that blocking agents are safe and effective. During routine dental examinations, pay attention to the integrity of the sealant, if any defects should be promptly reclosed. To do this, it is possible to obtain nearly 100% of the prevention of pit and fissure caries effect. In the past, the proposal to close only within 2 years after tooth eruption should be canceled. For those susceptible to caries pit fissure can not consider the time of the eruption of the tooth, all to do pit and fissure closed.
