Periapical lesions (PLs) occur as a result of pulpal inflammation and may rarely be seen in the absence of pulpal diseases. They are the most common pathological lesions affecting the alveolar bone.
This study aims to describe the clinicopathological features of PLs of the jaws with emphasis on the two most common types.
Histopathology records of PLs diagnosed from January 1990 to December 2012 at the Department of Oral Pathology, University College Hospital Ibadan, were examined and categorized into periapical cysts (PCs); periapical granuloma (PGs) and others. Clinical data and histopathological features of these PLs were reviewed and analyzed.
One hundred and four lesions met the criteria for this study and consisted of PGs with 71 (68.3%) cases and PCs with 31 (29.8%) cases and one case each of apical scar and pleomorphic adenoma. Age range of cases was 9 to 80 years (mean=35.6 ± 15.8years) with a peak at age group of 20-29 years. Females were more frequently affected with 51.9% of cases. PLs were most frequently diagnosed in the anterior maxillary region with 58 (56.9%) cases, while the most frequently involved tooth was the left maxillary central incisor with 23 (22.1%) cases.
Findings in this study are consistent with those of previous studies. It is important for all periapical pathological specimens to be submitted for histological examination to establish an accurate diagnosis and aid in the identification of sinister lesions that may present in the Periradicular region of teeth.
根尖周病变（PLs）是牙髓炎症的结果，在无牙髓疾病时很少见。它们是影响牙槽骨的最常见病理病变。
本研究旨在描述颌骨PLs的临床病理特征，重点关注两种最常见的类型。
检查了1990年1月至2012年12月在伊巴丹大学学院医院口腔病理科诊断的PLs的组织病理学记录，并将其分类为根尖周囊肿（PCs）、根尖周肉芽肿（PGs）和其他类型。回顾并分析了这些PLs的临床资料和组织病理学特征。
104个病变符合本研究标准，其中PGs 71例（68.3%），PCs 31例（29.8%），根尖瘢痕和多形性腺瘤各1例。病例年龄范围为9至80岁（平均=35.6±15.8岁），高峰年龄组为20 - 29岁。女性受影响更频繁，占病例的51.9%。PLs最常在前上颌区域诊断出，共58例（56.9%），而最常受累的牙齿是左上颌中切牙，共23例（22.1%）。
本研究结果与先前研究一致。所有根尖周病理标本都应提交进行组织学检查，以建立准确的诊断，并有助于识别可能出现在牙根尖周区域的恶性病变，这一点很重要。
