The question is asking whether the statement regarding the etching material's effect on dentin tubules is true or false. Specifically, it inquires about the depth of demineralization caused by the etching material, which is indicated to be between 3 to 5 micrometers.
Answer
True
The statement 'The etching material can demineralize the dentin tubules for 3-5 micrometers' is true.
Answer for screen readers
The statement 'The etching material can demineralize the dentin tubules for 3-5 micrometers' is true.
More Information
Etching with phosphoric acid typically demineralizes dentine to a depth of 3-5 micrometers. This process exposes collagen fibers which are crucial for adhesive bonding.
