Tx: immediate referral to ophthalmologist

27
Q

List the MOI, S/S and Tx of conjunctival foreign body .

A

description: dirt or other extraneous material on conjunctival membrane
s/s: foreign body sensation
first response: rinse eye with sterile water, evert lid and use wet Q-tip if necessary
May RTP if fully cleared

28
Q

List the MOI, S/S and Tx of corneal foreign body.

A

Corneal foreign body
material embedded in clear window of eye
s/s: reduced visual acuity, foreign body sensation, photophobic

Q

List the MOI, S/S and Tx of corneal abrasion.

A

scratch, scrape, erosion of clear window

s/s: decreased visual acuity, foreign body sensation, photophobia

heals in 24-48h with patch and/or drugs

tx: irrigate with sterile saline solution
patch eye
refer for ophthalmic exam

30
Q

List the MOI, S/S and Tx of corneal laceration.

A

MOI: blunt or sharp or trauma, previous laser eye surgery increases risks

S/S: decrease vision, increased light sensitivity, irregular pupil

911: ruptured globe/ embedded sharp object, associated injuries

urgent referral: visual field loss with flashers/floaters, visual acuity loss, photophobia, diploplia

38
Q

32, 8 per quadrants ==> 2 incisors, 1 canine, 2 premolars, 3 molars

39
Q

What are the three layers of teeth?

A

enamel: hard outer layer
cementum: coats root surface, attaches tooth to periodontal lig of socket
dentin: forms bulk of tooth/walls for pulp
pulp chamber: space in middle contains nerve, blood for tooth viability

40
Q

What are the 4 types of tooth luxations?

A

concussion: no breakage, loosening or displacement
subluxation: mobile but undisplaced

luxation: displacement of tooth, blood supply fully compromised
avulsion: tooth is out of socket

41
Q

How can you tell if its an alveolar fracture versus a tooth luxation?

A

alveolar fractures will show mobility for a group of teeth no tooth independently mobile

42
Q

What is one of the best ways to protect teeth?

A

wearing a mouth guard

43
Q

What is the management of a crown fracture?

A

need to cover fx part ASAP
need urgent dental tx to prevent infection and prevent need for root canal
locate missing pieces of teeth. Out of mouth, in soft tissue, swallowed, inhaled

44
Q

What is the management of a tooth avulsion?

A

replace tooth in socket ASAP (within 3 min)
rinse debris off tooth, don’t scrub tooth
handle tooth by crown, not root
clean a blood clot out of socket with light gentle irrigation
if can’t be re-implanted immediately, store tooth in appropriate medium, (egg white, coconut water, milk)
don’t let tooth dry out
don’t re-implant a baby tooth
