Introduction: Geographic and fissured tongues are the most common disorders of tongue. Therefore, this study aimed to determine the prevalence of this disorder in the female students of Yazd in 2013.

Methods: This analytic cross-sectional study was carried out applying observational technique, interview, and the information application form. In this study, 1230 students were selected via random cluster sampling including: 416 primary school students, 400 middle school students and 414 high school female students. Ultimately, the study were analyzed data spss via software (Ver. 20) applying Fisher exact,Logistic Regression, Chi-squared test and T- test.

Results: In general, the particular tongue disorders were observed in 320 samples (26%), among which 42 (3.4%) had only geographic tongue, 240(19.5%) had only fissured tongue and 38 (3.1%) had both of them. The results of multivariate logistic regression indicated that history of allergy (OR:16.83. P-value 0<00), and fissured tongue (OR:2.73. P-value 0<001) were significantly related to the geographic tongue.

Conclusion: The inspected tongue disorders within female students of Yazd were demonstrated to be highly prevalent. The results of the present study revealed a relationship between these two inspected disorders within the females. Furthermore, a significant relationship was observed between geographic and fissured tongues with the  allergy history and drug consumption or systematic diseases.
