问题陈述：头颈部的软组织钙化大多数可能不伴有临床症状，但可能表明某些病理状况。目的：本研究的目的是确定下颌骨区域锥形束计算机断层扫描（CBCT）图像中软组织钙化的患病率。材料和方法：在这项横断面研究中，对602例患者（包括294例男性和308例女性，平均年龄41.38±15.18岁）的CBCT图像进行了下颌骨软组织钙化的存在、解剖位置、类型（单个或多个）和大小的评价。所有CBCT图像均由NewTom VGi扫描仪采集。采用比值比和卡方检验进行数据分析，认为p< 0.05具有统计学意义。结果：602例患者中有156例（25.9%）下颌骨区域至少有一处软组织钙化。平均年龄51.7±18.03岁）。男性软组织钙化率明显高于女性（30.3% vs. 21.8%）。软组织钙化主要发生在下颌骨后部（88%），多为单发（60.7%）。软组织钙化的患病率随年龄增长而增加。大多数检测到的软组织钙化小于3mm（90%）。结论：下颌骨软组织钙化是一个相对常见的发现，尤其是在后部区域，更容易发生在男性和老年组。
Statement of the Problem: Most of the soft tissue calcifications within the head and neck region might not be accompanied by clinical symptoms but may indicate some pathological conditions. Purpose: The aim of this research was to determine the prevalence of soft tissue calcifications in cone beam computed tomography (CBCT) images of mandibular region. Materials and Method: In this cross sectional study the CBCT images of 602 patients including 294 men and 308 women with mean age 41.38±15.18 years were evaluated regarding the presence, anatomical location; type (single or multiple) and size of soft tissue calcification in mandibular region. All CBCT images were acquired by NewTom VGi scanner. Odds ratio and chi-square tests were used for data analysis and p< 0.05 was considered to be statistically significant. Results: 156 out of 602 patients had at least one soft tissue calcification in their mandibular region (25.9%. of studied population with mean age 51.7±18.03 years). Men showed significantly higher rate of soft tissue calcification than women (30.3% vs. 21.8%). Soft tissue calcification was predominantly seen at posterior region of the mandible (88%) and most of them were single (60.7%). The prevalence of soft tissue calcification increased with age. Most of the detected soft tissue calcifications were smaller than 3mm (90%). Conclusion: Soft tissue calcifications in mandibular area were a relatively common finding especially in posterior region and more likely to happen in men and in older age group.
