Diffuse pigmentation of the attached gingiva: case reports of physiological, racial hyperpigmentation and smoker ́s melanosis

Brown pigmentation of the oral mucosa is most commonly caused by the presence of the melanin pigment, produced by the melanocytes in the basal layers of the epithelium. Clinical representation (the coloration and the extent of the pigmentation) and its cause (physiological or pathological) can greatly vary. This poster presentation reports 4 patients primarily referred for the treatment of periodontitis, but also presenting with asymptom-atic, diffuse pigmentations of the gingiva. Patient 1 is a female of African origin with dark brown, diffuse pigmentation of the attached gingiva and areas of the buccal mucosa. Di-agnosed as physiological, racial hyperpigmentation, it was of no concern for the patient, thus requiring no further treatment. Patients 2 and 3 reported dissatisfaction with the brown appearance of the maxillary and mandibular attached gingiva on the labial sides of the canines and incisors. Medical history revealed patients were smoking up to 20 ciga-rettes/day. By excluding other factors, final diagnosis was smoker’s melanosis. Intraoral ex-amination of Patient 4 revealed diffuse pigmentation of the frontal areas of the attached gingiva in both jaws, of which patients was unaware, diagnosed as smoker’s melanosis. Interestingly, patient was a former smoker, having ceased smoking 3 years prior, without the expected disappearance of the pigmentation. Gingival depigmentation for aesthetic pur-poses can be carried out by several different treatment techniques. Furthermore, smokers should be supported in smoking-cessation and informed about its potential in pigmentation reduction. Dental professionals should be able to diagnose pigmentations correctly and plan treatment accordingly.
