目的探讨流动树脂用于预防性树脂充填(preventive resin restoration,PRR)的临床效果。方法 2008年6月~2010年6月在天津市河西区马场街社区卫生服务中心牙科就诊的磨牙窝沟龋患者56例(106颗患牙),随机分为两组,观察组用流动树脂充填预备好的窝洞及周围无龋的窝沟,对照组用复合树脂充填预备好的窝洞,周围无龋窝沟用窝沟封闭剂封闭。结果经过6个月、12个月的观察,6个月时观察组和对照组的充填物保留率差异无统计学意义(P>0.05),在12个月时二者的差异有统计学意义(P<0.05)。结论对于窝沟浅龋或者可疑的窝沟龋进行预防性树脂充填治疗中,使用流动树脂充填较传统的复合树脂联合窝沟封闭具有更好的临床效果。
Objective To investigate the clinical effect of flowable resin on preventive resin restoration (PRR). METHODS: From June 2008 to June 2010, 56 cases (106 teeth) of molar dental caries in dentists in Machang Street Community Health Service Center, Hexi District, Tianjin were randomly divided into two groups. The observation group was filled with mobile resin Prepared cavities and caries-free fissure around the control group with a composite resin filling the prepared hole, surrounded by no caries pit and fissure sealant closed. Results After 6 months and 12 months of observation, there was no significant difference in retention rate between the observation group and the control group at 6 months (P> 0.05), and there was a significant difference between the two groups at 12 months (P <0.05). Conclusion For the treatment of shallow fissure caries or suspected pit fissure caries in the treatment of prophylactic resin filling, the use of fluid resin filling is more effective than the traditional composite resin fissure ditch closure.
