目的探讨TPH3纳米复合树脂在年轻前磨牙畸形中央尖预防性充填的疗效。方法选择2008年3月—2011年9月在郑州市口腔医院儿童牙科就诊的年轻前磨牙畸形中央尖患者58例共患牙98颗,采用一次性磨除畸形中央尖盖髓后,按就诊顺序随机分组,实验组49颗患牙用TPH3纳米复合树脂充填的方法进行预防性治疗,对照组49颗患牙充填用玻璃离子充填进行预防性治疗。结果治疗后随访2年,对照组49颗患牙48颗治疗成功,1颗治疗失败,成功率98%;对照组49颗患牙35颗治疗成功,14颗治疗失败,成功率71.4%。两者比较差异有统计学。结论 TPH3纳米复合树脂应用于年轻前磨牙畸形中央尖进行预防性充填,是有利于患牙保存活髓,使患牙牙根得以继续发育。
Objective To investigate the curative effect of TPH3 nanocomposite resin on the prophylactic filling of young central molars. METHODS: From March 2008 to September 2011, 58 cases of central malformation of young premolar tooth distraction in Zhengzhou Dental Hospital were treated with a total of 98 congenital teeth. Randomly divided into groups, the experimental group 49 patients with TPH3 nanocomposite resin filling preventive treatment, the control group of 49 teeth filled with glass ion exchange prophylactic treatment. Results After 2 years of follow-up, 49 of the control group of 48 teeth were successfully treated. One of them failed. The success rate was 98%. In the control group, 35 of the 49 teeth were successfully treated and 14 failed. The success rate was 71.4%. The difference between the two statistics. Conclusions TPH3 nanocomposite resin is applied to the prophylactic filling of the central tip of young premolar deformity, which is beneficial to the preservation of vital pulp in the tooth so that the root of the affected tooth can continue to develop.
