This study was performed to identify correlations between keratocystic odontogenic tumor (KCOT) data from CT sections, and data on the KCOT clinical manifestation and resulting dental expenses.
Following local Institutional Review Board (IRB) approval, a seven-years of retrospective study was performed regarding patients with KCOTs treated at the Seoul National University Dental Hospital. A total of 180 KCOT were included in this study. The following information was collected: age, gender, location and size of the lesion, radiological features, surgical treatment provided and dental expenses.
There was no significant association between the size of the KCOT and age, gender, and presenting preoperative symptoms. In both jaws, it was unusual to find KCOTs under 10 mm. The correlation between the number of teeth removed and the size of the KCOT in the tooth bearing area was statistically significant in the mandible, whereas in the maxilla, no significant relationship was found. Dental expenses compared with the size of the KCOT were found to be significant in both jaws.
The size of KCOT was associated with a significant increase in dental expenses for both jaws and the number of teeth removed from the mandible. These findings emphasize the importance of routine examinations and early detection of lesions, which in turn helps preserving anatomical structures and reducing dental expenses.
本研究旨在确定来自CT断层扫描的牙源性角化囊性瘤（KCOT）数据与KCOT临床表现及由此产生的牙科费用数据之间的相关性。
经当地机构审查委员会（IRB）批准，对首尔国立大学牙医院治疗的KCOT患者进行了为期七年的回顾性研究。本研究共纳入180例KCOT。收集了以下信息：年龄、性别、病变部位和大小、放射学特征、提供的手术治疗以及牙科费用。
KCOT的大小与年龄、性别及术前症状之间无显著关联。在上下颌中，发现直径小于10mm的KCOT并不常见。下颌骨牙列区拔除牙齿的数量与KCOT大小之间的相关性具有统计学意义，而上颌骨则未发现显著关系。与KCOT大小相比，上下颌的牙科费用均具有显著性。
KCOT的大小与上下颌牙科费用的显著增加以及下颌骨拔除牙齿的数量相关。这些发现强调了常规检查和病变早期检测的重要性，这反过来有助于保留解剖结构并降低牙科费用。
