Abstract
Background: Oral mucosa which covers inside of the mouth is a complex structure that has been adapted for its particular function and anatomical location. Some oral conditions, despite their different physical features, are not pathological; rather, they are considered normal such as Linea Alba, Parotid Papilla, Geographic Tongue and Fissured Tongue. Materials and Methods: in this cross-sectional study 692 patients were registered through clinical examination and fulfillment of predesigned questionnaire. Diagnostic criteria in this study included the normal changes of the oral mucosa (including geographic tongue, fissured tongue, scalloped tongue, parotid papilla, palatal and mandibular torus, Lina Alba, frenal tag, leukoedema, Fordyce granules). Results: 692 people with an average age of 35years participated in this study. The overall sum of oral cavity normal variations was 806, 542 cases of which were female and 264 cases male. Conclusion: In this study 692 patients were examined by specialists; 494 cases, a sum of 71% had oral cavity normal variations. Linea Alba had the highest frequency among normal variations.

Oral mucosa, which covers inside of the mouth is a complex structure that has been adapted for its particular function and anatomical location [1]
Diagnostic criteria in this study included the normal changes of the oral mucosa, which were performed according to the recommendations of WHO [12] and were limited to visual examination
The present study is a cross-sectional descriptive one to assess the prevalence of Normal variation among patients who were referred to the Oral medicine department, Dental School, Qazvin. 692 patients were examined by specialists of which 71% had normal variation in their oral cavity
Summary
Oral mucosa, which covers inside of the mouth is a complex structure that has been adapted for its particular function and anatomical location [1]. Some oral conditions despite their different physical features are not abnormal but rather as considered normal. Clinical appearance suggests a final diagnosis [5, 6] It does not need therapy and by removal of etiologic factors, spontaneous recovery can be expected. Despite their different physical features, are not pathological; rather, they are considered normal such as Linea Alba, Parotid Papilla, Geographic Tongue and Fissured Tongue. Diagnostic criteria in this study included the normal changes of the oral mucosa (including geographic tongue, fissured tongue, scalloped tongue, parotid papilla, palatal and mandibular torus, Lina Alba, frenal tag, leukoedema, Fordyce granules). Conclusion: In this study 692 patients were examined by specialists; 494 cases, a sum of 71% had oral cavity normal variations.
