Orthodontists have to be able to detect, identify, and treat effec- tively or to address the patient to a specialist. Here we discuss this difference to make their diagnosis and management easier for the practitioner.

Erythematous (example: acute myeloid leukemia) or pigmented (example: Range >5 mm idiopathic macular melanoma). Papula <5 mm In relief, firm, non-liquid, protruding, circumscribed, palpable. Increased epithelio-conjunctival volume. Red, white, or pigmented. The plaque may result from the confluence of several Plaque >5 mm papules. Firm, non-protruding, round or oval, deep (of the chorion), sometimes painful, linked to Nodule inflammatory or tumoral (benign or malignant) involvement. Generally large. Keratotic, erythematous, or pigmented. Vegetation Hypertrophic or hyperplastic circumscribed epithelio-conjunctival proliferation consisting of growths (cauliflower appearance). Of variable morphology (filiform or lobulated appearanc- es). Pediculated or sessile. Usually refers to papillomas, warts, and condylomas. Vesicule <5 mm Elevated circumscribed intraepithelial elevation with serous or hemorrhagic fluid content. The thin roof is quickly eliminated in the mouth, giving way to erosion (secondary lesion). Bubble >5 mm Clear, yellowish, or hemorrhagic fluid collection. Fragile roof that breaks easily (formation of a secondary erosive lesion or post-bullous ulcerative lesion). May be intra- or subepithelial. Pustule <5 mm Vesicle that contains pus. A vesicle can turn into a pustule due to bacterial contamination. Erosion Loss of superficial substance (epithelial involvement without involvement of the chorion). Heals without leaving a scar. Most often secondary to a vesicle or an intraepithelial bubble after the rupture of its roof. Surface most often erythematous. Ulceration Loss of epithelial and conjunctive tissue. Leaves a fibrinous layer by exudation after removal of the basal membrane. More painful than erosion. Usually heals in about 10 days, some- times with cicatricial sequelae. Most common causes are canker sores, trauma, subepitheli- al bubbles, and carcinomas. 2 Sicard. L., Benmoussa. L., Moreau N., Salmon. B., Ejeil. A.-L.
