Prevalence of Soft Tissue Calcifications on Digital Panoramic Radiographs: A Cross-Sectional Study

Soft tissue calcifications are inconspicuous entities seen on orthopantomograms as incidental findings, often overlooked, which may be a result of underlying disorders. Hence, it is important to evaluate their location, extent, and cause, to determine their clinical significance which may warrant further investigations and appropriate interventions to avoid any complications.

To determine the prevalence of soft tissue calcifications on digitally acquired panoramic radiographs.

This cross-sectional, retrospective study analyzed panoramic radiographs of 2000 individuals to assess the prevalence and characteristics of soft tissue calcifications, which were tabulated based on parameters such as type of calcification, age, gender, and site.

The most common calcification noted on orthopantomogram was calcification of Stylohyoid ligament 139 (57.2%), followed by Tonsillolith 55 (22.6%), whereas the least common was Phlebolith 1 (0.4%). The maximum number of calcifications were present in the older age group, i.e., 53-70 years (41.2%).

Soft tissue calcifications are frequently detected on digital panoramic radiographs. While seemingly trivial, they may be an early indicator unsuspected pathology. Their prevalence increases with age, often indicating underlying systemic changes, which warrants early detection, timely referral and prompt management.
