What does concrescence refer to in dental terms?

Concrescence in dental terms specifically refers to the condition in which the cementum of two adjacent teeth fuses together. This phenomenon usually occurs when the roots of the teeth are in close proximity, leading to a joining of their cementum layers. Such fusion can happen due to various factors, including developmental abnormalities or external influences like periodontal disease.

This condition is particularly important to recognize in clinical practice because it can complicate tooth extractions, periodontal treatment, and overall dental management. Understanding concrescence helps dental professionals anticipate challenges that may arise during procedures involving the affected teeth.

The other options reflect different dental conditions or phenomena. For example, a decrease in tooth density relates to other issues, such as osteoporosis, tooth decay refers specifically to carious lesions promoting decay, and displacement of teeth involves movement rather than fusion. Therefore, recognizing concrescence's unique definition and implications is crucial for effective dental practice.
