Dental Assistant Practice Exam

Which dental instrument is primarily used for hand examination of tooth surfaces?

1. Probe

2. Excavator

3. Scalpel

4. Cotton Forceps

The correct answer is: Probe

The correct choice is based on the function of the dental probe, which is specifically designed for the hand examination of tooth surfaces. A dental probe typically features a thin, pointed tip that allows the dental professional to assess the condition of the tooth enamel, check for decay, and evaluate conditions such as periodontal disease by measuring pocket depths. This instrument is essential for clinicians to detect irregularities, plaque build-up, and early signs of cavities that may not be visible to the naked eye. In contrast, the other instruments serve different purposes. An excavator is primarily used to remove decayed tooth material, a scalpel is employed for cutting soft tissue during procedures such as surgeries, and cotton forceps are utilized for the handling of cotton products and other materials in dental practice. Each of these instruments is integral to various dental procedures but does not serve the same role in the hand examination of tooth surfaces as the dental probe does.
