Biopsy reports of specimens from the apices of 1659 teeth physically present at the time the biopsy was performed were reviewed. The following information was recorded from each report: (a) source of specimen, (b) sex of patient, (c) age of patient, (d) location of tooth associated with lesion, and (e) diagnoses reported. Data were recorded and analyzed by chi-square analysis to note significant differences. This study found that 52% of the lesions were granulomas, 42% cysts, 2% periapical scars, and 4% other disorders. No differences were found between males and females in regard to age and location of lesions. Overall, the most common location for lesions was the maxillary anterior, followed by maxillary posterior, mandibular posterior, and finally the mandibular anterior jaw. This also was the case for all age ranges except 60 to 69 yr of age where lesions in the maxillary posterior area were most common. More granulomas were detected in all areas except in the mandibular posterior area where cysts were more common.
对1659颗在活检时实际存在的牙齿根尖标本的活检报告进行了回顾。从每份报告中记录了以下信息：(a)标本来源，(b)患者性别，(c)患者年龄，(d)与病变相关的牙齿位置，以及(e)报告的诊断结果。通过卡方分析记录和分析数据，以注意显著差异。本研究发现，52%的病变为肉芽肿，42%为囊肿，2%为根尖瘢痕，4%为其他疾病。在病变的年龄和位置方面，男性和女性之间未发现差异。总体而言，病变最常见的位置是上颌前部，其次是上颌后部、下颌后部，最后是下颌前部。除60至69岁年龄段外，上颌后部区域的病变最为常见，其他所有年龄段也是如此。除下颌后部区域囊肿更为常见外，在所有区域均检测到更多的肉芽肿。
