# Diagnosis of cracked tooth syndrome is made by:
A. Biting on solid object and release of pressure
B. Only during bites
C. Percussion
D. All of the above
The correct answer is A. Biting on solid object and release of pressure
The bite test is useful in identifying a cracked tooth or fractured cusp when pressure is applied in a certain direction to one cusp or section of the tooth. It is also helpful in diagnosing cases wherein the pulpal pathosis has extended into the periradicular region causing apical periodontitis. The Tooth Slooth and the Frac Finder are the popular commercially available devices for the bite test.
