Comprehensive Dental Treatment Under Sedation in a Patient with Alzheimer’s Disease and Mixed Anxiety-Depressive Disorder: A Case Report

Background: Cognitive impairment and behavioral symptoms associated with Alzheimer’s disease can complicate dental assessment and treatment. Case presentation: A 76-year-old woman with Alzheimer’s disease, mixed anxiety–depressive disorder, sleep disturbances and hypertension presented with gingival bleeding, halitosis and reduced appetite. Limited cooperation hindered intraoral examination. Clinical and panoramic radiographic findings included extensive periodontal destruction, dental caries, root remnants and teeth with grade II–III mobility. Intervention: Following multidisciplinary medical assessment, comprehensive dental care was performed under sedation in an operating-room setting. Treatment included scaling, selective root planing, extraction of teeth with unfavorable prognosis and root remnants and direct restorations. Outcomes: The planned procedures were completed in one treatment session and caregivers received oral-hygiene instruction. Long-term healing, functional improvement and patient-reported outcomes were not documented. Conclusion: Individualized interdisciplinary planning and appropriate anesthesia support can facilitate necessary dental care in patients with dementia who cannot tolerate conventional treatment.
