different site of tumor, in patients referring to Mashhad Dental School.
Materials and Methods: Among the total number of 8115 biopsies taken during years 1349 to1384 at oromaxillofacial pathology department of Mashhad Dental School, 120 cases of oral minor salivary glands tumors were detected and selected for the study. Two time intervals of A (1349-1375) and В (1375-1384) were considered in which the frequency of pleomorphic adenoma was compared according to age, sex and site of the lesion.
The frequency of benign and malignant tumors of oral minor salivary gland tumors were also determined.
Results: Pleomorphic adenoma with the frequency percentage of 29.16 was the most benign tumor in oral minor salivary glands. The most frequent age of pleomorphic adenoma involvement was different between the two time intervais. The percentage of benign malignant tumors was higher in the first interval.
Conclusion: pleomorphic adenoma was the most frequent oral minor salivary glands neoplasm especially in the palate. The onset age of invelvement had decreased but female/ male ratio increased. Malignancy was more frequent in Interval B compared to А.
