背景:目前已经形成了法医牙科影像同一认定的共同原则,即主要根据牙齿、颌骨及其毗邻结构的生理解剖特征、病理变化和牙齿的各种治疗情况等进行个体识别.然而随着人们口腔保健意识不断增强、牙科治疗手段的不断进步,牙齿发生病变的情况正在逐渐地减少,因此单纯依靠牙齿病变和治疗特征进行同一认定方法已不能适应当前的形势.目的:针对口腔无病变和创伤的深圳地区成年汉族人群数字全颌曲面断层片,认识下颌牙齿及下颌骨观测指标测量值在分段赋值区段里的分布频率,评估其进行法医学同一认定的价值.方法:运用E-film workstation2.12软件对200例深圳地区成年人群的数字全颌曲面断层片进行精确测量,测量值运用Microsoft Office Excel 2003和SPSS 16.0软件进行统计分析.结果与结论:各观测指标的测量值在分段赋值区段里分布频率不尽相同,最大为96.5%.两张同源数字全颌曲面断层片之间的分段赋值匹配率最高为77.53%,最低为69.66%;两张非同源数字全颌曲面断层片之间的分段赋值匹配率最高为42.70%.结果可见数字全颌曲面断层片中牙齿测量指标和下颌骨各观测指标测量值分段赋值的分布频率具有多样性,可用于同一认定.

BACKGROUND:To date, we have reached a consensus of forensic dental identification according to physiological and anatomical characteristics and pathological changes of the teeth, jaw bones and its adjacent structures, as wel as the individual identification of various treatments for teeth. However, with the growing of awareness of oral health and the development of dental treatment method, dental problems are gradual y reducing. Thus, identification only depends on dental disease and treatment characteristics cannot meet the current situation. OBJECTIVE:To investigate the distribution frequency of surveying indexes of mandibular teeth and mandible in segment assignment section for the digital panoramic tomography of Chinese Han population in Shenzhen with oral lesions and trauma, and to evaluate its value in individual identification. METHODS:The digital dental orthopantomograms of 200 adults in Shenzhen were accurately measured with E-film Workstation2.12 software. And the data were statistical y analyzed with Microsoft Office Excel 2003 and SPSS 16.0 software. RESULTS AND CONCLUSION:The frequency of each observed index was different. The maximal one was 96.5%. The maximal matching probability of the section-numbers between two homologous dental orthopantomograms was 77.53%and the minimal was 69.66%. While the maximal matching probability of the section-numbers between two non-homologous dental orthopantomograms was 42.70%. The distribution frequencies surveying indexes of mandibular teeth and mandible in segment assignment section on dental orthopantomograms are polymorphic, and the method is suitable for forensic identification.
