Which of the following is a potential complication of concrescence?

In the context of concrescence, which is the fusion of the roots of two adjacent teeth by cementum, the potential complication that stands out is cyst formation. This occurs because the altered anatomy can create an environment where the normal drainage of the periapical area is compromised, leading to the accumulation of fluids and potentially forming a cystic lesion.

Cyst formation can result from the irritation of the dental pulp or periodontal structures due to the abnormal root configuration associated with concrescence. When the vital structures within the tooth or surrounding tissue are affected, it can lead to a pathological process where a cyst develops.

Understanding the implications of concrescence is crucial, particularly in treatment planning. If dental professionals are aware of the risk for cyst formation, they can take appropriate precautions during procedures that involve the affected teeth, such as extractions or endodontic treatments, to monitor for any complications that may arise.
