What is the primary cause of root resorption following dental trauma?

• A. Osteoblasts proliferating
• B. Osteoclasts eating root surface
• C. Cementum decay
• D. Pressure from adjacent teeth

Answer: (B)

Root resorption following dental trauma is primarily caused by the activity of osteoclasts, which are specialized cells responsible for bone resorption. Following a traumatic event, such as a fracture or luxation, there is typically a disruption in the normal healing process. This disruption can lead to inflammation and a localized increase in osteoclast activity near the tooth root surface. Osteoclasts degrade the mineralized tissue of the root, leading to resorption. This process is particularly prominent when the periodontal ligament and adjacent bone structures are damaged. The imbalance created by the increased osteoclast activity can compromise the structural integrity of the tooth root, making it susceptible to further issues. While other factors like osteoblast proliferation, cementum decay, and pressure from adjacent teeth may play roles in dental health, they are not the primary mechanisms driving root resorption specifically as a result of trauma. Osteoblasts promote bone formation, not resorption, while cementum decay does not directly lead to the active resorption observed following trauma. Similarly, pressure from adjacent teeth can lead to issues like tooth mobility but is not the primary cause of root resorption in this context. Thus, the action of osteoclasts is crucial for understanding the biological processes behind root resorption
