What is angular cheilitis?

Angular cheilitis is characterized as an oral fungal infection, typically caused by yeast organisms like Candida. It manifests as inflammation and cracking at the corners of the mouth, which can be quite uncomfortable. This condition occurs when the skin folds at the corners of the mouth become trapped in an environment conducive to fungal growth, often exacerbated by moisture from saliva. Factors that contribute to angular cheilitis can include nutritional deficiencies, dry skin, and systemic conditions that compromise the immune system.

In contrast, periodontal disease primarily affects the tissues around the teeth, causing gum inflammation and potential tooth loss but does not specifically involve the corners of the mouth. Similarly, while a bacterial infection of the gums can lead to gingivitis or periodontitis, it is not the same as angular cheilitis, which is distinctly a fungal condition. Therefore, identifying angular cheilitis as an oral fungal infection aligns with its clinical presentation and etiology.
