Chemical Gastroenterocolitis After Dental Root Canal Therapy With Camphorated and Mentholated Chlorophenol

The document is a case report about a 78-year-old man who developed chemical gastroenterocolitis, hair loss in the moustache area, and fingernail detachment after a dental root canal therapy using camphorated and mentholated chlorophenol (CMCP). The patient's symptoms, including abdominal pain and constipation, began four days after the dental treatment. Gastroscopy and colonoscopy revealed inflammation and polypus-like changes in his gastrointestinal tract. His symptoms improved after starting mesalazine therapy. The report suggests that oral application of CMCP can cause significant gastrointestinal inflammation and hair and nail loss, and recommends that patients with unexplained gastrointestinal inflammation be questioned about past dental treatments. It also suggests that ingestion of CMCP could cause alopecia and nail lifting.
