Comparing Mean Platelet Volume Values in Patients with Recurrent Aphthous Stomatitis and Patients with Behcet’s Disease

Recurrent oral aphthae (ROA) are among the most common diseases of the oral mucosa and 20% of the population is affected. It is an inflammatory condition whose etiology is not clearly known and appears in the oral mucosa as painful, recurrent, single or multiple ulcers (1, 2). It is thought to occur due to immunemediated epithelial damage as a result of the disruption of the immune system. The lesions usually appear as white membranes on the ground and as erythematous halo in the periphery. It is mostly seen in non-keratinized oral mucosa surfaces (3). There are 3 types as minor, major and herpetiform. While minor ulcers are less than 1 cm and heal without a scar, major aphthae are over 1 cm and the healing period can take weeks or months, and they heal by scarring. Herpetiform aphthae consist of a number of small minor aphthae in group (4).
