Osteosclerosis

Also known as: Bone sclerosis, Bone tissue densification

Osteosclerosis (lat. osteosclerosis) is a pathological change in bone structure, characterized by an increase in the volume of bone trabeculae and a reduction in bone marrow spaces. This leads to a significant increase in bone tissue density while maintaining the external contours of the bone.

Etiology and Pathophysiology

In dentistry, localized osteosclerosis of the jaw often acts as a protective response of the body to a chronic slow dental infection. The body densifies bone tissue around the root, creating a barrier to limit the spread of bacterial toxins. Unlike destructive processes, osteosclerosis does not destroy bone but compacts it.

Clinical significance

The process is asymptomatic and is only detected through radiological imaging, where the affected area appears significantly lighter (whiter) than the surrounding bone. The presence of osteosclerosis at the apex of a tooth root can be an essential diagnostic marker of chronic inflammation in the dental pulp.
