浅析自酸蚀粘结剂对160例小学生恒牙窝沟封闭的临床疗效评估

Since the Acid etch Adhesives for 160 Cases of Primary School Students Permanent Teeth Socket Channel Closed Clinical Curative Effect Evaluation

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 primary school in our country at present stage permanent teeth socket groove deeper phenomena using the acid etching adhesive sealing method is analyzed. Methods select our hospital from September 2011 to August 2012 were 160 cases of children with permanent teeth socket groove deeper, it can be divided into observation group and control group, give two groups of children with different methods for treatment. After treatment for 6 months and 12 months follow - up survey. Results： After the follow - up found that the corrosion from acid binder treated group, closed a tooth operation time than using phosphoric acid pickling treatment control group. And using the acid corrosion binder group in the follow - up of 6 months and 12 months of retention rate is significantly higher than the control group. And at the end of the treatment for 6 months and 12 months found that the number of cavities significantly lower than the control group, P 〈 0.05, statistically significant. Conclusion： After clinical treatment, learned that using the acid corrosion binder treated pupils permanent teeth socket channel has the operation time is short, high retention rate, recurrence rate, it is worth in clinical treatment for primary school students permanent teeth groove method.
