目的:观察氢氧化钙诱导年轻恒牙牙根发育的临床效果。方法:选择7～13岁患者因龋病、外伤等使牙髓坏死致牙根未发育完成的前牙及前磨牙76颗,去髓术后用氢氧化钙进行根尖诱导,定期复诊,X线牙片观察根尖发育及根尖闭合情况。结果:42颗前牙中38颗牙根闭合,4颗牙根没有变化;34颗前磨牙牙中32颗根尖闭锁,2颗牙根没有变化,临床成功率90.8%。结论:氢氧化钙诱导年轻恒牙根尖发育有较好的临床疗效。
Objective: To observe the clinical effect of calcium hydroxide on root development of young permanent teeth. Methods: A total of 76 anterior teeth and premolar teeth were obtained from 7 ~ 13-year-old patients with dental root necrosis due to dental caries, trauma and so on. After appendectomy, root apical induction with calcium hydroxide Tooth observation of apical development and apical closure. Results: Thirty-eight of the 42 anterior teeth were closed and no change occurred in the four teeth. There were 32 apical anterior teeth in the 34 premolar teeth and no change in the two teeth. The clinical success rate was 90.8%. Conclusion: Calcium hydroxide can induce the clinical development of young permanent root apical development.
