Aim: To evaluate the prevalence of soft tissue calcifications in orofacial region and their panoramic radiographic characteristics using digital panoramic radiographs among patients reporting to a tertiary dental hospital. Methods: 1,578 digital panoramic radiographs were retrieved from the archives and scrutinized for the presence of calcifications. Soft tissue calcifications were recorded according to age, gender, site (left or right). Data were analysed using Chi-square and Fisher’s exact test using SPSS software and a p < 0.05 was considered statistically significant. Results: Among the total number of radiographs, calcified carotid artery (34.3%), calcified stylohyoid ligament (21%), tonsillolith (10.3%), phlebolith (17.6%), antrolith (6.3%), sialolith (5.9%), rhinolith (2.5%) and calcified lymph nodes (1.9%) were identified. The most commonly observed calcifications were calcification of carotid artery and stylohyoid ligament and the least commonly observed calcifications were rhinolith and calcified lymph node. A statistically significant association of the presence of calcifications of carotid artery and stylohyoid ligament on the left and right side was observed in females and tonsillolith on the right side in males (p-value < 0.05). Considering the gender and age group, the occurrence of antrolith among males and rhinolith among females of young-adult population, tonsillolith among the males, calcified carotid artery and stylohyoid ligament among the females of middle-aged population was found to be significant. Conclusion: Soft tissue calcifications are often encountered in dental panoramic radiographs. Our study revealed that the soft tissue calcifications in orofacial region were more common in women and were found to be increased above 40 years of age.
