Which instrument in the basic set-up is used to explore tooth surfaces for irregularities?

• A. Explorer
• B. Mirror
• C. HVE
• D. Cotton pliers

Answer: (A)

Exploration of tooth surfaces for irregularities relies on tactile feedback from a hand instrument with a fine, pointed tip. The explorer is designed to be lightly dragged along the enamel and along grooves to detect texture changes, calculus deposits, caries, pits, and defective margins by feel. The mirror aids indirect vision and illumination, but it isn’t used to probe texture. The high-volume evacuator (HVE) provides suction to keep the area clear, not to assess surface texture. Cotton pliers are used to handle cotton materials, not for probing tooth surfaces. So, the instrument that best fits this task is the explorer.
