摘　　要：目的 :通过对影像学资料的回顾分析,初步观察分析北京地区80岁以上高龄患者缺失牙以及余留牙情况,以期为制定高龄患者的口腔医疗保健措施提供参考依据。方法:获取128名80岁以上初诊患者的曲面体层影像资料,由两名医生分别独立对口内除第三磨牙外的其他牙齿的情况进行判读,并分为缺失牙、种植牙、残根和残留牙四类。从患者个体水平及牙位水平对各类牙齿进行统计和分析。结果:所有研究对象平均余留牙数为17.84±7.36颗,47.66%的患者余留牙数不小于20颗。口内残根数平均为2颗。接受过种植治疗的患者为6人,仅占研究对象总数的4.69%。牙列缺失的比例1.56%。结论:通过曲面体层片对口腔内牙齿情况进行分析是一种较可靠的研究方法。北京地区门诊患者中,80岁以上患者平均余留牙不足20颗,磨牙缺失率较高。Objective：To investigate the tooth loss situation in patients over 80 years old in Beijing based on panoramic tomography.Methods：Panoramic radiographs of 128 patients was obtained and evaluated by two experienced dentist separately.Each tooth was classified as missing tooth,residual root,implant or remaining tooth.The result was described from patient level and tooth level.Results：Average number of remaining tooth is 17.84±7.362,each patient has 2 residual root on average.6 patient（4.69%） had received implant treatment.Proportion of edentulous is 1.56%.Conclusion：It is a reliable method to investigate tooth loss situation by using panoramic radiograph.Tooth number of patient over 80 years is less than 20,missing rate of molar is comparatively higher.
