摘要
目的探讨采用邻面去釉法关闭牙周炎患者前牙牙龈黑三角后牙槽骨附着水平的变化。方法选取牙槽骨无明显吸收的牙龈黑三角非牙周炎患牙20颗作为对照组,牙槽骨有吸收的牙龈黑三角牙周炎患牙36颗作为试验组。采用邻面去釉法治疗前后,拍摄全景片进行长度测量,获得待测牙齿切端至牙槽骨附着点处的距离,进行治疗前后的比较。结果对照组邻面去釉前牙冠切缘到牙槽嵴附着点的距离为(10.64±2.31)mm,邻面去釉后为(10.78±2.26)mm,差异无统计学意义(t=0.915,P=0.372);试验组邻面去釉前牙冠切缘到牙槽嵴附着点的距离为(11.77±1.86)mm,邻面去釉后为(11.86±1.88)mm,差异有统计学意义(t=2.286,P=0.028)。结论使用邻面去釉法消除牙周炎患者牙龈黑三角,牙槽骨有吸收现象。
Objective To investigate the effect of interproximal enamel stripping in the height of alveolar bone level of orthodontic patients with periodontitis who suffered from anterior teeth black triangle. Methods Twenty teeth which belonged to patients with black triangle but had no obvious alveolar bone absorption were selected to be control group. Thiry-six teeth which belonged to patients with black triangle who had 'alveolar bone absorption as experiment group. Interproximal enamel stripping was used to eliminate the black triangle, the length of incise to the alveolar bone attachment point was measured in panoramic, and the length before and after treatment was compared. Results Compared with the control group, there was difference in experimental group between before and after treatment, the data was statistically significant (P 〈 0.05 ). Conclusion Interprnximal enamel stripping may result in alveolar bone absorption when it is used to eliminate the black triangle of patients with periodontitis.
