目的:观察正畸治疗对患者牙周组织的影响。方法:随机选择90例将要接受正畸治疗的患者,均拔出第一前磨牙,采用固定矫治器治疗。选择25例错程度相似的病例作为对照。正畸治疗结束半年后检测两组病例的牙周状况,并拍摄曲面断层片。结果:两组间的菌斑指数及牙周袋深度没有显著差别,但两组间牙槽嵴顶到釉牙骨质界的距离有显著差别,且有性别差异。结论:正畸治疗对患者的牙周袋深度没有明显的影响,但会影响牙槽骨的高度。
Objective: To observe the effect of orthodontic treatment on periodontal tissues in patients. Methods: Ninety patients undergoing orthodontic treatment were selected at random, and the first premolar was extracted and treated with fixed appliance. Twenty-five cases with similar degree of error were selected as control. After six months of orthodontic treatment, the periodontal condition of the two groups of patients was examined and the curved section was taken. RESULTS: There was no significant difference in plaque index and periodontal pocket depth between the two groups, but there was a significant difference in the distance between the alveolar crest and the enamel cementum between the two groups with a gender difference. Conclusion: Orthodontic treatment has no significant effect on the depth of the periodontal pocket in patients, but affects the height of the alveolar bone.
