Oral osteonecrosis, specifically medication-related osteonecrosis of the jaw (MRONJ), is most commonly associated with surgical procedures involving the jawbone, particularly dental extractions. The extraction of molars, which often requires removing tooth roots from their sockets and can involve manipulation of surrounding bone, poses a significant risk of causing this condition, especially in patients undergoing therapies like bisphosphonates or other medications that impact bone remodeling.

In contrast, complete dentures, root canal treatment, and scaling and root planing are less invasive and do not typically result in significant bone manipulation. Complete dentures do not involve any surgical removal of bone, while root canal treatment is confined to the tooth itself. Scaling and root planing are periodontal procedures focused on cleaning the tooth surfaces and do not involve the removal of teeth or bone, thus further reducing the likelihood of triggering osteonecrosis.
