目的以传统的复合树脂+窝沟封闭方法为对照组,观察流动树脂在预防性树脂充填(preventive resin restoration,PRR)治疗中的临床疗效。方法选择门诊就诊儿童中至少一对同名恒磨牙有小的窝沟龋或窝沟可疑龋为研究对象,随机选择一侧为观察组,对侧为对照组;观察组用流动树脂充填预备好的窝沟及周围无龋的窝沟,对照组用复合树脂充填预备好的窝沟,周围无龋窝沟用窝沟封闭剂封闭。结果经过0.5年、1年、2年三个时间点的观察,观察组治疗成功率每年均高于对照组,在1年、2年时二者的差异有统计学意义(P<0.05)。结论对小的窝沟龋或窝沟可疑龋预防性树脂充填治疗中,应用流动树脂充填较传统的复合树脂+窝沟封闭有更好的临床疗效。
Objective To observe the clinical efficacy of fluid resin in the treatment of preventive resin restoration (PRR) with the traditional composite resin + pit and fissure sealant as the control group. Methods At least one pair of suspicious caries with pit or fissure caries in at least one pair of permanent molars with the same name was chosen as the study object. One side was randomly selected as the observation group and the contralateral as the control group. The observation group was filled with mobile resin The fissure and caries-free fissure around the fossa, the control group filled with composite resin prepared pit fissure, surrounded by no pit around the fissure sealant. Results After 0.5 years, 1 year and 2 years of observation, the success rate of observation group was higher than that of control group each year. There was significant difference between the two groups at 1 year and 2 years (P <0.05). Conclusions In the treatment of small pit and fissure caries or pit fissure suspicious caries prophylaxis, the application of mobile resin filling is better than the traditional compound pit and fissure sealant.
