A
- initially talking
- initially increased breathing and circulation rate
- initially alert
- irritable, confused, pale
24
Q
seizure treatment
A
- if repeated or prolonged consider 10mg midazolam via buccal mucosa
25
syncope treatment
elevate legs
26
Reversible pulpits
- mild inflammation to pulp
- tooth may respond more than normal to stimuli e.g. heat
- stimuli tend to produce sharp pain (a delta fibres) that resolves within 5-10 secs after stimuli removed
- cause of inflammation caries - pulp-dentine complex returns to normal
27
irreversible pulpitis
- dull aching pain lasting minutes or hours
- worsens at night or when lying down due to increased pulpal pressure
- will become necrotic if left untreated
- tx = XLA/RCT
28
necrosis
- blood supply non-existent
- negative to EPT and cold sensitivity
- radiographic PDL thickening and PA lucency
- tx= ends/XLA
29
ANUG - actue necrotising ulcerative gingivitis treatment
- ultrasonic debridement
- chlorohexidine mouthwash, oral hygiene instruction
- metronidazole 400mg 3x a day for 3 days
- or amoxycillin 500mg 3x a day for 5 days
30
ANUP - Actue necrotising ulcerative periodontitis treatment
- metronidazole 400mg 3x a day for 3 days
- chlorohexidine 0.2% 10ml - 2 x a day
31

- please cast impressions
- make upper and lower record blocks, with shellac base
33
tooth trial lab card

=- return wax trial dentures on mounted casts. specific instructions e.g. diastemas
34
final denture card - PROS
re-trial; remount casts and make specified changes for second trial

35
What is the vibrating line?
junction between hard and soft palate
36
Mandibular soft tissue landmarks - pros
- retromolar pads
- mylohyoid line
- sublingual crescent
- lingual frenum
- buccal shelf
- mentalis muscle
- labial frenum
37
pros - maxillary anatomical landmarks
- hamular notches
- tuberosities
- palatine fovea
- labial and buccal frenums
38
maxillary anatomy considerations in pros
- 1 degree support hard palate
- 2 degrees support alveolar ridge, rug area, buccal shelves
- post dam along vibrating line, in front of the palatine fovea
- incisive papilla and palatine torus must be relieved
- labial and buccal farina much not be encroached upon
39
Mandibular anatomy considerations in pros
- 1 degree support buccal shelf
- 2 degree support buccal and lingual slopes of alveolar ridge
- lingual pouch used for retention
- floor of mouth is mylohyoid muscle
- lingual, buccal and labial fraena must be accounted for
40
fissure sealants: gold standard for moisture control
dental dam
41
needle size for infiltration
short 25mm
42
needle size for inferior alveolar nerve block
long 35mm
43
Inferior alveolar nerve block injection site
- 6-10mm above lower occlusal plane
- needle entry at junction of buccal fat pad and pterygomandibular raphe
- syringe lies over contralateral 5
- advanced to bone contact
- if no bony contact reposition syringe distally
44
What LA would you give to pt with high blood pressure or heart problems?
- 3% prilocaine with felypressin
- contains synthetic vasoconstrictor so effects of la will last
45
LA for pt with latex allergies
- Prilocaine/Citanest 3% with felypressin
