Angular Cheilitis: Although the sores of angular cheilitis may become infected by the fungus Candida Albicans (thrush), or other pathogens, studies have linked the initial onset of angular cheilitis with nutritional deficiencies, namely riboflavin (vitamin b2)and iron deficiency anemia, which in turn may be evidence of poor diets or malnutrition (e.g. Celiac disease). Zinc deficiency and others.

Nystatin cream : Nystatin and triamcinolone cream. 30gram tube. Apply after meals and at bedtime, for 10 days to corners of mouth this little known antifungal cream placed on the corners of the mouth several times a day almost always heals this for my patients. Use when you get flare-ups as they will still occur from time to time. Get a prescription for this from your dentist or doctor.

Many possible causes: Angular stomatitis or cheilitis is a common disorder with many causes including infections(fungal and bacterial), vit b2 deficiency, iron or zinc deficiency, syndromes like plummer-vinson, excess vit a intake, or from patients with dry lips with a habit of licking their lips excessively, causing chapping and cracking. Any problem lasting 8 yrs should warrant a good workup and exam.
