Which component is replaced by osseous tissue in the case of ankylosis?

• A. Periodontal ligament
• B. Cementum
• C. Enamel
• D. Roots

Answer: (A)

In the context of ankylosis, the periodontal ligament is the component that is replaced by osseous tissue. Ankylosis is a condition where there is an abnormal fusion between the tooth and the bone, which typically occurs when the periodontal ligament, which normally serves to attach the tooth roots to the alveolar bone, becomes compromised. In this situation, the normal connective tissue that allows for some movement and provides cushioning is replaced by bone tissue, resulting in a rigid attachment. This fusion to the surrounding alveolar bone can lead to various dental complications, including difficulties in tooth movement during orthodontic treatments and changes in occlusion. The presence of osseous tissue where the periodontal ligament should be signifies a lack of normal mobility and can influence the overall health of the dental structure involved. The other components like cementum, enamel, and roots are not directly involved in the process of ankylosis in the same way; they do not undergo replacement by osseous tissue as a consequence of this condition. Instead, ankylosis primarily affects the space where the periodontal ligament should exist, leading to the characteristic bony fusion.
