Common superficial oral lesions include recurrent aphthous stomatitis, candidiasis, recurrent labial herpes, erythema migrants, hairy tongue, and lichen planus [1,2].
The recognition and the classification of oral lesions have a considerable significance in the process of diagnosis. The correct diagnosis is accomplished through the knowledge of the various lesions, a thorough history and a comprehensive clinical oral examination for the precise diagnosis in the process of differentiating between the specific conditions, management, as well as counselling [3-5]. Ulceration due to aphthous stomatitis (AS) represents the most common oral mucosal inflammatory disease, most frequently starts during the second decade of life, affects about 20% of the population and has a female predilection [6,7]. The etiology of AS is varied and is due to the perturbation of the oral ecosystem. The oral environment is unique, and is able to induce reactivity of products from the prosthetic restoration materials. The biological reactivity of dental materials in the oral cavity can induce reactions of the oral tissues against the bacteria’s adhesion, reactions to the mechanical irritation, to the direct toxic effect, and to the allergens [8]. Habitually, AS lesions begin with prodromal burning sensation, 2-48 hours before the appearance of an ulceration. AS debut is painful. It has the appearance of a rounded ulceration masked by fibrin, with erythematous margins, located especially on the nonkeratinized oral mucosa [9,10].
