| 摘 要： | 目的 探讨冷光牙齿漂白技术对活髓牙牙髓的影响.方法 选择因正畸需要拔除的40颗活髓牙,对照组(10颗)不做任何处理拔除,其余30颗牙采用冷光漂白后分别即刻拔除(15颗)和漂白7 d后拔除(15颗).40颗牙齿均制作病理切片,镜下观察牙髓组织形态.结果 所有活髓牙漂白前后均未发现有任何临床症状.漂白后即刻拔除组、7 d后拔除组以及对照组在镜下均表现为正常的牙髓组织结构,与对照组相比漂白后即刻拔除组及7 d后拔除组牙髓组织均无明显改变.结论 冷光牙齿漂白技术对活髓牙牙髓无明显不良影响,是一项安全可靠的漂白技术.

| Abstract: | OBJECTIVE: To investigate the influence of bleaching technique on vital tooth pulp. METHODS: A total of 40 vital teeth extracted for orthodontics were selected, of which, 10 teeth without any treatment served as control, 15 teeth were extracted instantly after bleaching and 15 teeth were extracted 7 days after bleaching. Slides were made from all these three groups and subject to pathological examination under microscope. RESULTS: No clinical symptoms were found in all the teeth before and after bleaching. All teeth in the three groups showed normal pulp on pathological examination. CONCLUSIONS: Bleaching did not affect vital tooth pulp and is a safe technique. |
