Introduction and Objectives

Soft tissue calcifications (STCs) in the maxillofacial area are relatively common. They are often dfetected as indicental findings on routine radiographic examination. The aim of this study is to evaluate etiology, clinical symptoms and imaging characteristics by using additional imaging methods such as cone beam computed tomography (CBCT) and ultrasonography (US) of STCs detected on panoramic radiographs (OPGs).

Materials and Methods

The study population consisted of 69 patients aged 18 years old and above who were determined STCs on OPGs. STCs were evaluated by CBCT or US according to preliminary diagnosis. CBCT for tonsillitis, anthrolith and US for sialoliths, calcified lymph nodes and the carotid artery calcifications were taken. Participants were interviewed about etiologic factors and clinical symptoms of STCs.


STC was not observed in US of some patients who were 3 tonsillitis, 8 sialoliths, 8 antroliths, 9 calcified lymph nodes, 8 carotid artery calcifications. There was significant correlation between the presence of carotid artery calcification and diabetes mellitus (p=0.01), hypertension (p=0.04), hyperlipidemia (p=0.00), Xerostomia was the most common symptom in the patients who had sialolith (p=0.01). Long-standing infection in the head and neck region was identified in five patients with calcified lymph nodes.


It is important to identify STCs correctly in the head and neck region to determine whether treatment or further investigation is required. Some calcifications require no intervention or long-term follow-up, whereas others may be life-threatening and underlying cause requires treatment. Therefore, the STCs on OPGs may be examined by imaging modabilites such as CBCT and US.


When the STCs are adjacent to bone, it is difficult to determine whether the calcification on OPG is within bone or soft tissue. Additional imaging techniques are useful.
