Which of the following is NOT a stated application of the Microetcher sandblaster?

• A. Remove discoloration and stains
• B. Roughen surface for bonding
• C. Etch tooth structure
• D. Cut tooth structure

Answer: (D)

The main idea here is understanding what a microetcher sandblaster is designed to do in tooth surface preparation. This device uses a stream of fine abrasive particles to lightly abraid the enamel or dentin surface, creating a micro-roughened area that helps resin-based materials bond more securely. Because of this gentle, surface-focused action, it can also help remove superficial stains and debris, aiding both cleanliness and bonding readiness. It is not a cutting instrument: it doesn’t remove significant tooth tissue or shape the tooth like a drill would. Using it to cut tooth structure would risk unnecessary tissue loss and damage, which is outside its intended use. Therefore, the statement describing cutting tooth structure is not a stated application of the Microetcher sandblaster.
