RESUMEN
Introduction: Atrophic tongue or smooth tongue is resulted from atrophy of the filiform papillae. The tongue often shows a shiny red appearance. This lesion may be seen in many systemic diseases
Method: This descriptive analytic study was conducted on 200 patients referred to Isfahan health clinics in spring 2015. A questionnaire about demographic characteristics and history of mouth diseases was filled out for each patient and they were clinically examined afterwards. If the atrophic tongue was observed, a sample was taken by swab from the site of the lesion to assess fungal infection. For positive fungal cultures, Candida species were detected using germ tube method. Data were analyzed using chi[2] and binomial test and through SPSS15
Results: Of the studied patients, 174 ones had systemic diseases and 26 patients [13%] had atrophic tongue. Candida was found in 73.1% of the lesions. Germ Tube detected 57.9% Candida Albicans and 42.1% Candida Glabrata. Atrophic tongue showed no significant association with dry mouth, burning sensation of tongue, age and gender
Conclusion: This study showed a significant prevalence of atrophic tongue in patients with systemic diseases. Therefore, systemic diseases should be controlled and treated. There is high chance of detecting Candida in atrophic tongue with equal chance of detecting Candida Albicans and Candida Glabrata in this lesion
