目的:观察BEAUTIFUL FLOW流动型聚合瓷用于第一恒磨牙窝沟封闭的临床效果。方法:7～8岁儿童120例480颗健康的第一恒磨牙分为2组:试验组用BEAUTIFUL FLOW流动型聚合瓷进行一侧窝沟封闭术,对照组用光固化窝沟封闭剂Estiseal F作为自身对照。随访3年。结果:术后1、2、3年复查,试验组的封闭材料完全保留率分别为94.29%、87.50%、79.49%,对照组分别为86.19%、79.35%、69.23%,试验组术后1、2、3年的封闭材料完全保留率高于对照组,差异有统计学意义(P<0.05)。术后1、2年龋病发生率差异无统计学意义(P>0.05),但术后3年试验组龋病发生率为1.92%,对照组为8.33%,差异有统计学意义(P<0.05)。结论:BEAUTIFUL FLOW流动型聚合瓷是一种可靠的恒牙窝沟封闭材料,值得临床推广使用。
Objective: To observe the clinical effect of BEAUTIFUL FLOW flow-type polymeric porcelain for the first molars pit and fissure sealant. METHODS: A total of 480 healthy first molar molars from 7 to 8 years old were divided into two groups. The experimental group was treated with BEAUTIFUL FLOW flow-type polymeric porcelain on one side. The control group was treated with light-cured pit and fissure sealant Estiseal F As their own control. Followed up for 3 years. Results: At 1, 2 and 3 years after operation, the complete retention rates of the occlusive materials in the experimental group were 94.29%, 87.50% and 79.49%, respectively, while those in the control group were 86.19%, 79.35% and 69.23% The complete retention rate of closed materials for 2 and 3 years was higher than that of the control group, with significant difference (P <0.05). There was no significant difference in the incidence of dental caries between the first and second year after operation (P> 0.05), but the prevalence of caries was 1.92% in the three years after operation and 8.33% in the control group, with significant difference (P < 0.05). CONCLUSION: BEAUTIFUL FLOW flowable polymeric porcelain is a reliable permanent pit fissure sealant, which is worthy of clinical promotion.
