Pain • It is perhaps the most commonly experienced symptom in dentistry. • Yet, a precise definition of pain does not exist as pain has a subjective/ psychophysiological aspect (a painful stimuli for one individual may not be painful for another) • Arbitrarily, pain can be defined as any unpleasant experiences may it be emotional, mechanical/physical or chemical with or without tissue damage. Dual nature of Pain • Pain like other sensations (touch, hot, cold, etc.) has a physioanato...

1. For lower premolars, the purpose of inclining the handpiece lingually is to, A. Avoid buccal pulp horn B. Avoid lingual pulp horn C. Remove unsupported enamel D. Conserve lingual dentine - ANSWER A. Avoid buccal pulp horn Explanation 1- avoid BUCCAL pulp horn 2- conserve ling. dentine So take A and B if available 2. For an amalgam restoration of a weakened cusp you should, A. reduce cusp by 2mm on a flat base for more resistance B. reduce cusp by 2mm following the outli...

of dentine sensitivity - answer1. Innervation of dentine (nerve fibres within tubules) 2. Odontoblast transducer mechanism (would require odontoblasts to be present entire tubule length) 3. Hydrodynamic theory (fluids in tubules disturbed by stimulus, changes stimulate odontoblasts which leads to nerve discharge) ©THEBRIGHTSTARS 2024 Describe the pulpal sensory supply (3) - answer- Max & mand branch of trigeminal nerve - Nerve endings predominantly nociceptive (pain) - Contains A-delta...
