Idiopathic Osteosclerosis among UiTM Dental Centre Patients: A Retrospective Study Idiopathic osteosclerosis (IO) represents asymptomatic radiopaque masses within the jaw. IO is commonly found as an incidental finding in panoramic radiographs. The purpose of the present study is to determine the prevalence of IO among Universiti Teknologi MARA (UiTM) Dental Centre patients and to investigate the radiographic parameters of IO located in the maxilla-mandibular region. Panoramic radiographic images of patients attending UiTM Dental Centre from 2016 to 2020 were examined. Parameters such as gender, age, site, shape, size, and association with tooth were evaluated. The data obtained were analysed using SPSS version 27. Pearson chi-square test was used to evaluate the relationship between the parameters. IO was identified in 108 (9.67%) out of 1,117 panoramic radiographic images that were reviewed. There was a slightly higher prevalence of IO in female patients with 58 (53%) over male patients. Most of the radiographically identified IO were located in the posterior mandibular region, constituting 83% of the cases. Pearson chi-square test revealed a significant relationship between size and gender (p-value < 0.05). Significant associations were found between site and gender and association with tooth and foci (p-value < 0.01). The prevalence of IO among UiTM Dental Center patients was observed to be low at 9.67%. There was a higher occurrence of IO in female patients compared to males, and the posterior mandibular region emerged as the most common site where IO was radiographically identified. The accurate radiographic identification of IO is essential for providing a precise diagnosis and formulating an appropriate treatment plan.
