Periodontitis is a chronic inflammatory disease that affects the supporting structures of the teeth, including the gums, periodontal ligament, and alveolar bone. Unlike gingivitis, periodontitis involves irreversible destruction of the tooth's supporting apparatus, leading to pocket formation, attachment loss, and eventual tooth loss if left untreated.
The prognosis for periodontitis depends on several factors including the severity of disease, patient compliance with treatment, and risk factors. Early-stage periodontitis can be effectively managed with non-surgical therapy, while advanced cases may require surgical intervention. The key to successful treatment is early detection, appropriate therapy, and long-term maintenance care.
