Currant symptoms, past & recent treatment
Pain – location,nature,duration,stimuli,relief,referred
Clinical examination- swelling, facial asymmetry, periodontaldisease, discharging sinuous, caries, restoration, fracture, attrition,abrasion, erosion, and abfraction
Diagnosis tests – percussion, palpation, mobility, pocket
Pulp sensibility test – electric, cold, heat
Radiographic test - IOPA, tube sift, bite wing, panoramic
Other test – biting on individual cusp, trans-illumination, localanaesthesia test, test cavity
Investigations –removal of caries of restoration, trans- illuminationof cavity.

Pulp Testing
• Moribund pulp may give possitive results, multirooted teeth give complicated results. Ideal wayof measuring vitality leiser dopler flowmetermessure blood flow to the pulp
• Electronic gives false possitive reading due tostimulation of PDL
• Thermol pulp test• Heat guttapercha sticks• Cold ethil chloride• ice sticks
