【摘要】：目的系統(tǒng)篩選頜面影像法醫(yī)學同一認定的識別指標,制定全口牙型識別指標編碼。方法隨機選取620例有牙齒治療史者、150例牙齒有病變無治療史者的數(shù)字全口牙位曲面體層片進行觀測,根據(jù)牙齒的生理變異、病理改變和治療特征篩選全口牙型識別指標,并按設(shè)計的編碼標準和原則對其全口牙型逐一編碼,最后分別統(tǒng)計兩組全口牙型的多樣性以評估其價值。結(jié)果620例牙齒有治療史者中共有619種全口牙型編碼,全口牙型多樣性為99.84%;150例牙齒有病變無治療史者中共有146種全口牙型編碼,全口牙型多樣性為97.33%。結(jié)論選出的全口牙型識別指標對牙齒異常者進行法醫(yī)學同一認定具有實際應(yīng)用價值。
[Abstract]:Objective to screen the same recognition index of maxillofacial image forensic medicine systematically and make the coding of the whole mouth tooth type recognition index. Methods A total of 620 cases with history of tooth treatment and 150 cases with tooth lesions without history of treatment were randomly selected for observation of digital full-mouth surface film. The parameters of full-mouth tooth type recognition were screened according to the physiological variation, pathological changes and therapeutic characteristics of the teeth. According to the coding standard and principle of the design, the whole tooth type was coded one by one, and the diversity of the two groups was counted to evaluate its value. Results there were 619 types of complete tooth coding in 620 cases with history of tooth treatment. The diversity of total tooth type was 99.84%. There were 146 kinds of complete tooth type coding and 97.33 type diversity of total mouth tooth type in patients with no history of tooth disease. Conclusion the selected full-mouth tooth type recognition index has practical application value for the identification of abnormal teeth in forensic medicine.
