Which of the following statements is true concerning bond strength?

Question

Quizplus · Accepted Answer

Wetter dentin with more holes is more difficult to bond to consistently than shallower dentin.Bonding to enamel usually achieves consistently high bond strengths of around 30 MPa (megapascals).The bond strength to dentin is usually less than to enamel and varies according to how deeply into dentin the cavity preparation extends.The dentin near the dentinoenamel junction (DEJ)has fewer dentinal tubules,occupying 14% of the dentin surface,and they are smaller in diameter than in dentin closer to the pulp.Deeper dentin contains more tubules,and they are larger in diameter,occupying 20% to 30% of the dentin surface.
