most commonly caused by different Candida species such as Candida Albicans, Candida Glabrata and Candida Tropicalis resulting in oral Candidiasis. There are several predisposing factors to fungal infections such as systemic disease for example Diabetes, recent antibiotics, use of steroid inhalers etc . Management includes identifying and addressing contributory factors, the use of topical/systemic anti-fungal agents, oral and denture hygiene instruction. Different presentations of oral Candidiasis include: Pseudomembranous Candidiasis Erythematous Candidiasis Denture Stomatitis Antibiotic Candidiasis Angular Cheilitis Median Rhomboid Glossitis Chronic Hyperplastic Candidiasis Chronic Mucocutaneous Candidiasis Autoimmune Lichen Planus: A chronic inflammatory disease with different forms of oral presentations. The most classic appearance of Lichen Planus is the presence of white streaks in inner cheek, tongue, and gum. Desquamative Gingivitis can be seen in patients with Lichen Planus. Biopsy is done for definitive diagnosis of Lichen Planus. Graft versus Host Disease: An autoimmune disease developed following bone marrow transplant in which its oral presentation is similar to Lichen Planus Pemphigus Vulgaris:An autoimmune chronic disease with clinical presentation of formation of superficial and large blisters which then burst into ulcers on the skin or mucous membrane. Mucous Membrane Pemphigoid: Autoimmune disease which affects only mucous membranes with clinical presentation of hard and rigid blisters which then rupture eventually into deep ulcers. Cutaneous Lupus Erythematosus: These present as oral discoid lesions which may be present on the inner cheek and behind the lips. White papules may also be present. Hypersensitivity Reaction Lichenoid Reaction- Intra-oral lesion which shares the appearance of Lichen Planus but arises due to contact hypersensitivity to certain dental materials or drug-induced. Traumatic Frictional Keratosis: This typically presents as white plaques on the oral mucosa due to mechanical trauma. When the cause of frictional keratosis is removed the white patch may resolve Hyperplastic reactive lesions or nodular swellings These occur in the oral mucosa due to low grade inflammation or trauma (1, 2). They develop where the mucosa is subjected to chronic minor irritants, mechanical or infective (4). They most frequently occur on the buccal mucosa (inner cheek) along the occlusal line where the teeth meet and the gingivae (the mucosa which covers the gums); reactive nodules occurring here are specifically categorised as epulides instead of polyps. Also the alveolar ridge (the gum where the teeth erupt up from, or if missing, where they used to be) and the hard palate (roof of the mouth) (1). The most common are
