In vitro researches which evaluate mechanical properties of dental materials are valuable tools in Dentistry since they help to make predictions for clinical practice. The microtensile bond test is a relatively recent mechanical method whose essence is the division of the resin-bonded teeth into diminutive slabs that are trimmed in such a manner that tensile force will be concentrated on the bonded interface during testing, allowing a more uniform stress distribution on the surface and reducing the occurrence of cohesive failures. This work presents a review in the literature focusing the major characteristics, advantages, applications and limitations of microtensile testing in Dentistry.
