Prevalence of soft tissue calcifications in CBCT images from the Oral and Maxillofacial Radiology Service at UNAB, Viña del Mar, Chile.

open access: yesJournal of Oral Research, 2020
Soft tissue calcifications can indicate the presence of more serious, potentially life-threatening pathologies. Therefore, their study can lead to an early diagnosis of those conditions that have not yet become clinically apparent.
