Question: 1 / 400

Which of the following instruments is used for tactile discovery of decay?

Mouth mirror

Explorer

An explorer is used for tactile discovery of decay because it is a sharp and thin instrument that can easily detect any soft spots or holes in the teeth. A mouth mirror, on the other hand, is primarily used for indirect vision and reflection of the mouth during dental procedures. A periodontal probe is used to measure the depth of the pockets between the teeth and gums. A scaler is used for removing plaque and tartar from the teeth. These instruments are not designed for tactile discovery of decay, making them incorrect options.
