Metronidazole Induced Aphthous Ulcer with Angular Cheilitis

Metronidazole, chemically a nitroimidazole is an antiprotozoal drug, which has broad spectrum cidal activity against anaerobic protozoa, anaerobic and microaerophillic bacteria. It was introduced in 1959 for trichomoniasis, and later found to be highly active amoebicide.

Low level laser therapy in the treatment of aphthous ulcer.

The lesions healed completely within 3-4 days and a follow-up for 1 showed no recurrence in these patients. ...
