The interactions between torus and several factors such as age, gender, and dental status have not been studied comprehensively. The purpose of this study was to determine the effect of gender on the mandibular cortical index (MCI) and to investigate a possible association between torus mandibularis (TM) and MCI.
The study consisted of 189 consecutive patients referred to Department of Oral Diagnosis and Radiology of Hacettepe University within 30 workdays. Patients who did not have systemic disorders affecting bone density were included; and the age, gender, dental status and existing TM of the patients were recorded. Morphology of the mandibular inferior cortex was determined according to Klemitti's classification on panoramic radiographs.
MCI was affected by age and gender (P < 0.05). No significant relationship was found between TM and MCI (P > 0.05).
In the study population, MCI was affected by age and gender. As age increased, semilunar defects could be seen on the cortex of the mandible and MCI values increased. Women appeared to have higher MCI values than men.
下颌隆突与年龄、性别和牙齿状况等多种因素之间的相互作用尚未得到全面研究。本研究的目的是确定性别对下颌骨皮质指数（MCI）的影响，并探讨下颌隆突（TM）与MCI之间可能存在的关联。
该研究包括在30个工作日内连续转诊至哈杰泰佩大学口腔诊断与放射科的189例患者。纳入未患有影响骨密度的全身性疾病的患者；记录患者的年龄、性别、牙齿状况和现存的TM。根据全景X线片上的克莱米蒂分类法确定下颌骨下缘皮质的形态。
MCI受年龄和性别的影响（P < 0.05）。未发现TM与MCI之间存在显著关系（P > 0.05）。
在研究人群中，MCI受年龄和性别的影响。随着年龄的增加，下颌骨皮质可出现半月形缺损，且MCI值升高。女性的MCI值似乎高于男性。
