Prevalence of oral manifestations in patients with lupus erythematosus in a sample of the Egyptian population: a hospital based cross-sectional study.

Background: Several systemic diseases manifest themselves in the oral cavity. Dentists who are unaware of these lesions will possibly miss them. This cross-sectional study aimed to assess the prevalence of oral manifestations in patients with LE in a sample of the Egyptian population. Methods: The present cross-sectional study was performed on 189 patients attending the Internal Medicine Department, Rheumatology Clinic in EL Qasr El Ainy Hospital, Cairo University. Every patient was examined clinically after completing a questionnaire. Patients' medical records were evaluated.   The oral manifestations were assessed according to the WHO guide to physical examination of the oral cavity and classified according to their morphologic aspects and localization. Results: Out of 189 patients, there were 182 females (96.3%) and seven males (3.7%). The prevalence of oral lesions in SLE patients was 55.6%. The most affected site was the tongue 25.7%. The most common clinical aspect was patches, 53%. About 77.1% of the lesions were asymptomatic.  Conclusions: The present study emphasizes the importance of early diagnosis of oral lesions to recognize patients with SLE as the WHO considers oral manifestations of SLE a widespread state. Also, the implementation of oral hygiene measures to improve patients' nutritional state and health-related quality of life is recommended.
