The hallmark sign that differentiates hypercementosis from other dental pathologies is the integrity of the periodontal ligament. Hypercementosis is characterized by an abnormal build-up of cementum on the roots of teeth, which can lead to increased tooth mobility and other complications but typically does not affect the periodontal ligament's integrity. In dental radiographs, hypercementosis may appear as a symmetrical widening of the periodontal ligaments without the presence of radiolucency associated with periodontal disease.

In contrast, other dental pathologies often involve issues that compromise the periodontal ligament or result in the presence of a radiolucent rim, indicating infection or severe periodontal disease. For instance, periodontal disease would manifest as a loss of attachment, possibly affecting the integrity of the periodontal ligament. Therefore, the preservation of the periodontal ligament is a crucial distinguishing factor for hypercementosis, highlighting its significance in diagnosis.
