Necrotizing periodontitis (NP) is a severe inflammatory condition of the periodontium triggered by bacterial infection, often exacerbated by reduced immune function or other systemic vulnerabilities. In some patients, NP can progress rapidly, posing serious health risks. We report a 73-year-old male patient dependent on nursing care who presented with pronounced gingival pain and intraoral bleeding. His medical history included cerebral infarction and type 2 diabetes mellitus, contributing to immunosuppression and functional impairment. Examination revealed characteristic signs of NP, including crater-like ulcerations of the interdental papillae, extensive gingival bleeding, and purulent discharge. Management involved an interprofessional approach: periodontists, dentists, and dental hygienists instructed nursing staff on effective oral hygiene techniques, including thrice-daily brushing using the Bass method. Initial periodontal therapy consisted of full-mouth scaling and meticulous root surface debridement employing both hand and ultrasonic instruments. Hopeless teeth were subsequently extracted. The patient now receives dental follow-ups every two weeks to monitor and maintain oral health, which remains stable.
