The study aimed to describe the diagnostic imaging features of idiopathic osteosclerosis (IO) to aid in differential diagnosis of similar dentomaxillomandibular conditions.
An archive of 550 dentomaxillofacial radiographic (panoramic radiography (PR) and cone beam computed tomography (CBCT)) images and 33,000 histopathological records were reviewed to identify IO cases. Chi-square, Student's t test, and ANOVA tests, with a significance of p < 0.05, were applied for comparative analysis. In addition, we analyzed various studies to present a short review.
After meticulous observation, 36 images of 34 patients revealed 60 IO lesions in 31 PR and 5 CBCT. Sex, age group, anatomical site, shape, regularity, and root relationship showed statistical significance: sex and age group (p = 0.046), sex and IO regularity (p = 0.007), age group and IO regularity (p = 0.014), anatomical site and IO shape (p = 0.010), anatomical site and IO regularity (p = 0.003), and IO shape and IO regularity (p = 0.002). We presented a short review from 26 articles, including retrospective, cross-sectional, and longitudinal studies, documenting 2307 patients with 2435 IO lesions from 51,160 imagiological examinations.
A radiographic diagnostic profile of IO may guide the clinical practitioners in differentiating an incidental radiopacity. PR is a preliminary examination, with CBCT facilitating the IO diagnosis.
Knowledge of imaging characteristics variability of idiopathic osteosclerosis is crucial for accurate diagnosis process when incidental radiopacities are found in the panoramic radiographs, thus avoiding unnecessary biopsies. CBCT scans facilitate the interpretation of idiopathic osteosclerosis overlapping the mandibular canal.
本研究旨在描述特发性骨硬化（IO）的诊断影像学特征，以辅助类似的牙颌面下颌骨疾病的鉴别诊断。
回顾性分析了 550 例牙颌面影像学（全景放射摄影术（PR）和锥形束计算机断层扫描（CBCT））图像和 33000 份组织病理学记录，以确定 IO 病例。应用卡方检验、Student's t 检验和 ANOVA 检验（p<0.05 有统计学意义）进行比较分析。此外，我们还分析了各种研究，以提供简短的综述。
经过仔细观察，34 名患者的 36 张图像显示 31 张 PR 和 5 张 CBCT 中有 60 个 IO 病变。性别、年龄组、解剖部位、形状、规则性和根关系具有统计学意义：性别和年龄组（p=0.046），性别和 IO 规则性（p=0.007），年龄组和 IO 规则性（p=0.014），解剖部位和 IO 形状（p=0.010），解剖部位和 IO 规则性（p=0.003），以及 IO 形状和 IO 规则性（p=0.002）。我们从 26 篇文章中进行了简短的综述，包括回顾性、横断面和纵向研究，记录了 51160 次影像学检查中的 2307 名患者和 2435 个 IO 病变。
IO 的放射诊断特征可指导临床医生区分偶然出现的不透射线性。PR 是初步检查，CBCT 有助于 IO 诊断。
了解特发性骨硬化的影像学特征变化对于在全景放射片中发现偶然出现的不透射线性时进行准确诊断过程至关重要，从而避免不必要的活检。CBCT 扫描有助于解释与下颌管重叠的特发性骨硬化。
