Hypercementosis is a nonneoplastic deposition of excessive cementum that is continuous with the normal radicular cementum¹.
What is Hypercementosis?
Hypercementosis is a thickening or blunting of the root due to excess cementum, surrounded by an intact PDL space, as evidenced in the photo above. Hypercementosis was found to be most common in the mandibular molars, but can occur in all teeth (either isolated or multiple)¹. It can be confused with a cementoblastoma, though a cementoblastoma is usually associated with pain and continual growth.
What causes Hypercementosis?
There are multiple, weak factors that are associated with causing hypercementosis, including occlusal trauma, adjacent inflammation such as that seen with rarifying osteitis, and teeth that are unopposed. However, it is seen that there is a strong relationship between hypercementosis and Paget’s disease of the bone. If generalized hypercementosis is evidenced by a patient, it may indicate a discussion that the patient is suffering from Paget’s, as well¹.
Is treatment required for Hypercementosis?
No treatment is required, though treatment planning for extraction of the affected tooth may require modifications. Teeth affected by hypercementosis often require surgical extraction due to the large thickening of the root, and caution should be applied on any tooth that exhibits the appearance of hypercementosis.
