According to studies, untreated periodontal disease leads to what major consequence?

Untreated periodontal disease primarily results in progressive loss of attachment, which is a critical consequence of the condition. Periodontal disease, characterized by inflammation and infection of the supporting structures of the teeth, results in the breakdown of the periodontal ligament and alveolar bone. As the disease advances, the attachment between the teeth and the surrounding tissues deteriorates, leading to increased tooth mobility and eventually tooth loss if not addressed.

The process begins with gingivitis, which can advance to periodontitis if left untreated. In periodontitis, the inflammatory response causes destruction of the connective tissue and bone that supports teeth. This loss of attachment is measured clinically and is a key indicator of the severity of periodontal disease. Understanding this progression is essential for diagnosis and treatment planning, as well as recognizing the importance of early intervention to prevent irreversible damage.

The other options, such as an increase in gingival hyperplasia, improved oral health, and stabilization of attachment levels, do not reflect the outcomes associated with untreated periodontal disease. Thus, the correct understanding of the implications of periodontal disease emphasizes the critical nature of progressive loss of attachment as a major consequence of neglecting treatment.
