目的探讨可见光固化窝沟封闭剂治疗磨牙窝沟龋患者的临床效果。方法选取2012年4月至2013年4月辽宁省北票市中心医院收治的50例磨牙窝沟龋患者(80颗患牙),采用随机抽签分组方式分为A、B两组,每组25例(40颗患牙)。分别采用不同方式来治疗(A组给予可见光固化窝沟封闭剂治疗,B组采用传统窝沟封闭术治疗)后,比较两组患者治疗效果。结果治疗后2年、3年随访,A组患者磨牙窝沟龋发生率均明显低于B组,差异均有统计学意义(均P<0.05);治疗后1年、2年、3年随访,A组患者涂膜保留率均明显高于B组,差异均有统计学意义(均P<0.05);A组患者不良反应总发生率明显低于B组,差异有统计学意义(P<0.05)。结论采用可见光固化窝沟封闭剂治疗磨牙窝沟龋临床效果显著,可有效控制龋发生率,并且涂膜保留率也较高,治疗可行性和安全性较高。
Objective To investigate the clinical effect of visible-light-cured pit and fissure sealant in the treatment of molar pit and fissure caries. Methods Fifty cases of dental caries (80 teeth) from April 2012 to April 2013 in Beipiao Central Hospital of Liaoning Province were randomly divided into two groups (A and B), 25 Example (40 teeth). Were treated with different ways (Group A treated with visible light-cured pit and fissure sealant, Group B treated with conventional pit and fissure sealant), and compared the therapeutic effect of the two groups. Results After 2 years and 3 years of follow-up, the incidence of dental caries in group A was significantly lower than that in group B (all P <0.05). After 1, 2 and 3 years of follow-up (P <0.05). The total incidence of adverse reactions in group A was significantly lower than that in group B (P < 0.05). Conclusion The treatment of pit and fissure caries with visible light curing pit and fissure sealant has significant clinical effect, which can effectively control the incidence of caries, and also has a higher retention rate of coating film. The feasibility and safety of treatment are high.
