Physiologic and Pathologic Calcifications of Head and Neck Significant to the Dentist

This article aims to help the practitioner identify structures found in routine three-dimensional imaging studies of the head and neck region and understand their significance and possible need for intervention. The prevalence of advanced imaging in dental practice, especially cone beam computed tomography, highlights the need to recognize and identify various high-density structures that are, in fact, soft tissue calcifications or alterations of normal bony anatomy. The wide range of these findings includes both benign and malignant pathologic entities as well as age-related calcifications and remodeling of normal anatomic structures and dystrophic calcifications.
