目的:为对现阶段我国小学生恒牙窝沟较深的现象采用自酸蚀粘结剂进行封闭的方法进行分析。方法:选取本地某医院在2011年9月~2012年8月间收治的160例恒牙窝沟较深的患儿,患儿年龄在7~12岁,完全萌出第1或是第2恒磨牙336颗。根据患儿家属意愿,将其分为观察组和对照组,2组在人数与龋坏的牙齿上并没有显著的差异性,具有可比性,P>0.05,统计学无意义,给予2组患儿采用不同的方法进行治疗。在治疗后的6个月和12个月进行随访调查。结果:经过随访发现,采用自酸蚀粘结剂进行治疗的观察组,封闭1颗牙的操作时间明显比采用磷酸酸蚀进行治疗的对照组要短。且采用自酸蚀粘结剂的观察组在随访的6个月和12个月的保留率明显高于对照组。并且在治疗结束的6个月和12个月内发现龋齿的数量明显低于对照组,P<0.05,统计学有意义。结论:经过临床治疗,了解到采用自酸蚀粘结剂治疗小学生恒牙窝沟具有操作时间短,保留率高,复发率低的特点,是值得在临床上使用的治疗小学生恒牙窝沟较深的方法。
OBJECTIVE: To analyze the phenomenon of occlusion of self-etching adhesive in deep dent of permanent dentition in primary school in our country. Methods: A total of 160 children with deep permanent fossa who were admitted to a hospital in China from September 2011 to August 2012 were selected. The children were 7 to 12 years old and had complete eruption of the first or second molars 336 pieces. According to the wishes of the families of the children, they were divided into observation group and control group. There was no significant difference between the two groups in the number of teeth and carious teeth, comparable, P> 0.05, statistically meaningless, giving 2 groups of patients Children use different methods for treatment. Follow-up surveys were performed at 6 months and 12 months after treatment. RESULTS: After follow-up, it was found that in the observation group treated with self-etching adhesive, the operation time of closing one tooth was significantly shorter than that of the control group treated with phosphate acid etching. And the retention rate of the observation group with self-etching adhesive at 6 months and 12 months follow-up was significantly higher than that of the control group. And the number of dental caries found in the 6 months and 12 months after the end of treatment was significantly lower than the control group, P <0.05, statistically significant. Conclusion: After clinical treatment, it is learned that the use of self-etching adhesive for the treatment of primary dentition pit has the advantages of short operation time, high retention rate and low recurrence rate, which is worthy of clinical treatment. Deep method.
