摘要: 目的:探讨不同程度氟斑牙患者下颌骨骨密度(bone minceral density,BMD)的差异。方法:选取我院就诊的正畸患者80例,根据氟斑牙程度分为重度组、中度组、轻度组和对照组。患者均拍摄曲面断层片,采用曲面断层下颌指数(panoramic mandibular index ,PMI)为测量指标分析患者的下颌骨BMD,进行统计学分析。结果:轻度组、中度组、重度组PMI指数均低于对照组,且与氟斑牙程度呈反比,差异均有统计学意义(P<0.01)。结论:氟斑牙患者下颌骨BMD降低,且氟斑牙程度越重BMD越小。

Abstract: Objective: To compare the mandibular bone mineral density with different degrees of dental fluorosis. Methods: Eighty orthodontic patients were divided into heavy group, medium group, mild group, and control group. Mandibular bone mineral density was measured with panoramic mandibular index. Results: The mandibular bone mineral density of experimental groups was lower than that of control group, and inversely proportional to the degree of dental fluorosis (P<0.05). Conclusion: Dental fluorosis reduced the mandibular bone mineral density, the more severely the degree of dental fluorosis exhibited, the lower the bone mineral density was.
