What is a vesicle?

  1. A solid mass greater than 1cm

  2. A fluid-filled sac less than 1cm in diameter

  3. An elevated lesion containing pus

  4. A broad-based lesion

The correct answer is: A fluid-filled sac less than 1cm in diameter

A vesicle is defined as a fluid-filled sac that is typically less than 1 centimeter in diameter. This terminology is frequently used in medical and dental contexts to describe certain types of lesions or blisters on the skin or mucous membranes. Vesicles can form as a result of various conditions, including infections, allergic reactions, or other dermatoses, and they contain serous or clear fluid. In this context, understanding the characteristics of a vesicle helps healthcare professionals accurately identify and differentiate it from other types of lesions, such as nodules or pustules, which have different defining features. Recognizing these distinctions is crucial for diagnosis and management in dental practices and related fields.
