Improvements in Oral Lichen Planus Following Periodontal Treatment in a Patient With Metabolic Dysfunction-Associated Steatotic Liver Disease: A Case Report.

Oral lichen planus (OLP), a chronic inflammatory mucocutaneous disease, is known to be associated with liver disease. Additionally, associations between periodontal disease and metabolic dysfunction-associated steatotic liver disease (MASLD), as well as cardiovascular disease, have been reported. Herein, we report a case of a 68-year-old male who presented at a dental clinic with OLP, which showed signs of improvement after treatment for periodontal disease. The patient had hepatic dysfunction and steatosis, which was complicated by angina pectoris. He was diagnosed with OLP and periodontal disease. Subsequent close examination of his liver led to a diagnosis of MASLD. Treatment for periodontal disease and enhanced oral self-care improved the OLP lesions and liver function values. This case demonstrates that collaboration between different medical disciplines can significantly impact patient health.
