Dental OSCE (Objective Structured Clinical Examination) Practice Exam

The ventral and lateral surfaces of the tongue are typically associated with varicosities, which are dilated veins that may appear due to age or other factors. This area is where these vascular changes are more commonly observed, as the ventral surface has a thinner mucosal layer, making the underlying veins more prominent. Additionally, the lateral aspects can also show these varicosities due to the anatomy and the presence of numerous blood vessels.

Varicosities can sometimes be mistaken for other lesions; however, their distinctive appearance can help in identifying them. While the dorsal surface might show other changes or conditions, it is less characteristic for varicosities. The tip and base of the tongue do not typically exhibit these vascular changes either, as their vascular supply and anatomical features differ from those found on the ventral and lateral surfaces. Understanding this concept can aid in differential diagnosis during clinical examinations.
