Background:
Dermatologic diseases are not only represented by lesions affecting the skin but also by manifestations that may involve the mucous membranes, including oral mucosa.
Objectives:
To evaluate the frequency of oral manifestations associated with dermatologic diseases considering location and clinical characteristics of the lesions found and also gender, age and race of patients.
Method:
It was an observational, cross-sectional study of patients who sought for treatment at the Dermatology Service of the University Hospital (Hospital Presidente Dutra-HUPD); UFMA, between October 2007 and October 2008 (n=88).
Results:
Age varied from 5 to 88 and there was predominance of female patients. 35% of the cases studied were diagnosed as lichen planus; 33% as lupus erythematosus; 24% as erythema multiforme; 7% as pemphigus vulgaris and 1% as pemphigoid group. Oral manifestations were more common among patients suffering from lichen pplanus (51%) and lupus erythematosus (20%). The most common clinical presentation found was reticular lichen planus located most predominantly in the buccal mucosa.
Conclusions:
It is essential that dentists know these pathologies to be able to diagnose them in an early stage of the disease and to direct patients to adequate treatment. Furthermore, intraoral examination should be included as a routine practice in dermatological services.
