Desquamative lesions are often preceded by bullae. • 3.Ecchymosis-Oral ecchymoses normally originate from trauma clinically appearing as an area of oral submucosal hemmorhage greater than 2 cm. at its greatest dimension. • 4.Endophytic-An oral mucosal lesion that extends inwards to the adjacent tissues and are characteristically indurated. • 5.Erosion-The epithelial surface of the oral mucosa is thinning characterized by being red in colour orerythematous. • 6.Erythematous-The oral mucosa is red in colour resulting either from erosion of the epithelial surface or from increased vascularity. • 7.Exophytic-An oral mucosal lesion that extends outward from the adjacent mucosa. • 8.Indurated-An oral mucosal lesion that is firm when palpated. • 9.Keratinized-An adherent white patch that cannot be removed or wiped off caused by excess keratin on the epithelial surface of the oral mucosa. • 10.Macule- flat, circumscribed, pigmented lesion on the oral mucosa. • 11.NeoplasmAbnormal new mass of tissue • 12.Nodule- elevated, circumscribed lesion on the oral mucosa. • 13.Papillary- oral mucosal lesion with a surface consisting of numerous blunted projections. • 14.Papule-A well circumscribed, slightly elevated solid lesion on the oral mucosa. • 15.Pedunculated-Refers to a mode of attachment to the adjacent mucosa by a narrow stalk • 16.Petechiae-Small hemorrhages in the oral submucosa characterized by multiple small erythematous spots on the affected mucosa • 17.Pseudomembrane-A non-adherent covering on an oral ulcer that consists of an accumulation of necrotic debris.Pseudomembranes are normally white to yellowish in colour. • 18.Sessile-Refers to a mode of attachment to the adjacent mucosa by a broad base • 19.Ulcer-localized area demonstrating a complete loss of oral epitheliumExample: apthous ulcer • 20.Verrucous-An oral mucosal lesion with a surface composed of numerous elongated projections.Example: verrucous carcinoma • 21.Vesicle-small blister less than .5 cm. at its greatest dimension on the oral mucosa • #dentabest #ndeb #inbde #adatexam #oralpathology #dentalstudent #dentistrystudent #dentalstudenteducation #dentalstudents #dentist #dentistry #dentistryknowledge #dentistryworld #dental
