 Detailed history:Recent dental restorations, occlusal adjustmentsParafunctional habits (bruxism)Pain history: character, intensity, relation to chewing, etc.

 Clinical examination:Periodontal probing

 Bite tests:Patient is asked to bite on various items such as a toothpick, cotton roll, rubber abrasive wheels, or wooden stickPain/tenderness increases as the occlusal force increases, and relief occurs once the pressure is withdrawn (diagnostic)

 Dye test:Special stains such as methylene blue or gentian violet are frequently used to highlight the cracks

 Vitality tests for individual tooth are usually positive

 Radiographs are not reliable (since cracks usually occur in a mesiodistal direction)

 Transillumination is an important aid in diagnosing the cracks
