what is the hydrodynamic theory? you have fluid within your dentinal tubule and when you place any stimulus to the outside of that tooth it triggers the fluid within the dentinal tubule to move wither in an outward or inward direction the movement stimulates the odontoblast
what do the dentinal tubules look like in a person who has sensitivity? 8x as many and 2x a wide
what are neural acting agents? directly effect the nerve itself, effect the odontoblast, does not block the stimulus from getting to the odontoblast
what are tubular blocking agents? precipitate that forms on top of the dentinal tubule or travels in the tubule and causes plug
if the patient has a low reaction to pain...they have a what threshold? high pain threshold
if the patient has a high reaction to pain...they have a what threshold? low pain threshold
what are unmylinated C nerve fibers? slow conduction of pain, takes more pain before it is triggered dull aching pain that lingers PULPITIS
What are militated A nerve fibers? fast in conduction, patients feel it immediately, takes little pain before it is triggered, as soon as you remove the stimulus the pain goes away dentin hypersensitivity
