INBDE (Integrated National Board Dental Examination) Practice Exam 2025 - Free Practice Questions and Study Guide

Pleomorphic adenomas are benign tumors that commonly affect the salivary glands, particularly the major salivary glands such as the parotid gland, which is the largest salivary gland located near the ear. However, the most common site of occurrence for a pleomorphic adenoma is actually the palate, which is the roof of the mouth. This can be due to the fact that the palate contains a large number of minor salivary glands, which can also be affected by these tumors. Therefore, options A and B are incorrect as they refer to major salivary glands, and option D is incorrect as it refers to the buccal mucosa, which is the inner lining of the cheeks and does not contain salivary glands. Option C is the most accurate as it specifies the most common site for a pleomorphic adenoma.
