The purpose of this study was to investigate the relationship between: (1) children's caries score (dmft, DMFT) at the time of sealant placement; and (2) "success" (measured as being caries-free) of that tooth at follow-up visits.
An existing database of over 38,000 sealants (10,038 children) placed between 1997 and 2002 by the Jefferson County Health Department's Community Based Sealant Program, Birmingham, Ala, was used in the analysis. Only children returning for followup visits after the initial placement of the sealants were included in this study, resulting in 6,452 sealants (2,097 children). Logistic regression analysis was performed to determine the differences in sealant success between children with a dmft score of 0 vs a dmft score of >0 at baseline, and a DMFT score of 0 vs a DMFT score of >0 at baseline.
In the permanent and primary dentitions, those who had no caries at the time of sealant placement (dmft/DMFT=0) had a significantly higher success of sealants during years 1 to 5 compared to those with a caries score of greater than 0 (dmft/DMFT>0; P<.023, P<.002, respectively).
Children with previous caries experience may be at a higher risk for sealant "failure" (measured as caries on a tooth surface previously sealed) after 1 year and, therefore, may require more diligent sealant maintenance.
本研究的目的是调查以下两者之间的关系：（1）放置窝沟封闭剂时儿童的龋病评分（dmft、DMFT）；（2）随访时该颗牙齿的“成功”情况（以无龋来衡量）。
分析了阿拉巴马州伯明翰市杰斐逊县卫生部门基于社区的窝沟封闭剂项目在1997年至2002年间放置的超过38000颗窝沟封闭剂（涉及10038名儿童）的现有数据库。本研究仅纳入了在初次放置窝沟封闭剂后前来进行随访的儿童，最终得到6452颗窝沟封闭剂（2097名儿童）。进行逻辑回归分析以确定基线时dmft评分为0与>0的儿童之间，以及基线时DMFT评分为0与>0的儿童之间窝沟封闭剂成功情况的差异。
在恒牙列和乳牙列中，放置窝沟封闭剂时无龋（dmft/DMFT = 0）的儿童在1至5年期间窝沟封闭剂成功的概率显著高于龋病评分为大于0（dmft/DMFT>0）的儿童（分别为P<.023，P<.002）。
有既往龋病经历的儿童在1年后窝沟封闭剂“失败”（以先前封闭的牙齿表面出现龋病来衡量）的风险可能更高，因此可能需要更勤勉地维护窝沟封闭剂。
