Senses

Question 1

trigeminal nerve

Answer 1

mandibular - inferior alveolar
anterior - mental nerve which exits mandible via mental oramen, supplyies sensory branches to chin and lwoer lip

Question 2

paraesthesia

Answer 2

abnormal sensation, tingling or prickling due to temp damage of IAN

Question 3

dysethesia

Answer 3

abnromal unpleasant sensation felt when touched, caused by damage to peripheral nerves

Question 4

gag reflex

Answer 4

prevent material entering pharynx
evoked by mechanical stimulation of fauces, palate, posteror tongue, pharynx
no ejection of material, clinical issue

Question 5

gag reflex nerve

Answer 5

afferent response from IX
efferent response from V, IX, X, X, XIII
salivary glands stimulated

Question 6

RPD + gag reflux

Answer 6

if placed too posteriorly, issues with retention and stability

Question 7

Bell’s Palsy

Answer 7

facial muscle weakness/paralysis
effects - cant wrinkle brow, droopy eyelid, cant close eye, inability to puff cheeks
FACIAL NERVE
causes - infection, diabetes, L:A infiltration to facial nerve
when given too far distally and parotid gland is penetrated through loose grandulae tissue, affects terminal branches

Question 8

complications of ID block

Answer 8

facial nerve paralysis palsy
reassure, protect eye with pad, recover in an hour, stay within practice
make sure bone is contacted

Question 9

overdentures

Answer 9

retains PD mechanoreceptors
finer discrimination of food texture, tooth contacts and levels of functional loading
better appreciation for food and more precise conrorl of mandibular movement
psych - not total loss, eventual transition

Question 10

loss of PD mechanoreceptors influence

Answer 10

control of jaw function, precision of magnitude, direction, rate of occlusal load application

Question 11

mechanoreceptors

Answer 11

very sensitive, asses direction of forces applied to teeth
contributes - mastication, salivation, interdental discrimination

Question 12

interdental discrimination

Answer 12

gauge extent if mouth opening, coordination of masticatory movements, monitor size of food particles, detect high spots, detect material between teeth
format of polo = 2 point discrimination

Question 13

loss of mechanoreceptors in complete dentures

Answer 13

not enough sensory informatio. to restore necessary natrual feedback pathways to motor function
inherently unstable during normal functional jaw movement due to this loss

Question 14

dysphagia

Answer 14

diffucu,ty swallowing
cause - stroke, brain injury, MS, gastro reflux, tumours

Question 15

smell and taste link

Answer 15

smell stimulates salivary glands
infection of nasopharynx leads to loss of olfactory sense [anosmia], hard to discern between tase and olfaction, interchanging terms

Question 16

nociceptors

Answer 16

response to intense stimuli associaed with pain
pup most important
alos muscles, joints, mucosa
