70
teeth most affect in dental injury and between what ge
Most victims between ages of 8 -15 yrs old Teeth most affected: upper incisors
71
how many teeth per quadrant of mouth
8
72
teeth in mid-line in
2 incisors, 1 canine, 2 premolar 3 molars
73
what can we see when we smille
crowns
74
root are attached to and hidden by
Roots are hidden supporting structures which attach to skull via peridontal ligs
75
what are the 3 layer of the teeth
All teeth have 3 layers: * * Enamel – hard outer layer caps the tooth Cementum – coats root surface, attaches tooth to peridontal lig of socket Dentin – forms bulk of tooth/walls for pulp
76
what is located in the pulp chamber
space in middle contains nerve, blood for tooth viability
77
crown fracture may involve what
enamel only * enamel and dentin * enamel, dentin, and pulp * The more severe the fracture, the greater discomfort, more immediate the need for treatment by a dentist.
78
what is a root fracture
Breakage of the root of a tooth * Surrounding teeth are also likely involved * Trauma usually greater than in crown fx.
79
what is tooth luxation- concussion
Breakage of the root of a tooth * Surrounding teeth are also likely involved * Trauma usually greater than in crown fx.
80
what is a tooth subluxation
a mobile but undisplaced tooth, sensitivity may be some bleeding at gum margins
81
what is tooth luxation
displacement of tooth, intrusive, extrusive, labial lingual, or lateral depending on force direction blood supply is fully compromised.
82
what is tooth avulsion
tooth is “out of socket”
83
what is a alveolar fracture
Fracture of the supporting bony ridge of the teeth, called the alveolus
84
if an athlete have mobility for a group of teeth what could he have
The affected area will show mobility for a group of teeth
85
dental injuries examination
Work top-to-bottom , inside out * Look for fluid, note its colour * Look for lacerations,contusions,abrasions * Wound under chin...jaw fracture? * Some injuries apparent, others hidden * Do not assume absence of other injuries
86
dental injury verification
* Mobility of teeth in affected area by gently trying to move them with gloved hand instrument best-to pick up subtle movement En bloc movement is sign of alveolar fx
87
what is the finger pressure test
mild pressure inward then outward on teeth
88
difference between concussion dental injury and subluxation
concussion -> no looseness subluxation -> loose but not displaced
89
A tooth chipped to dentin layer will show
colour change from whitish enamel to the more yellow dentin. Sensitive to hot/cold
90
crown fracture management
If pulp (nerve) involved, see small bleeding from tooth itself. 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 (pneumonitis!)
91
tooth displacement management
Whether root fx, crown root fx, tooth luxation,or alveolar fx: PUT AFFECTED TEETH BACK INTO AS NORMAL A POSITION AS POSSIBLE Hold them in place: custom or stock mouthguard, or cotton rolls. Immediate dental consult for wire splint
92
with tooth avulsion, tooth need to be place in socket within
3 min
93
tooth avulsion management
Rinse debris off tooth, DON’T scrub tooth * Handle tooth by the crown, NOT the root * Clean a blood clot out of socket with LIGHT GENTLE irrigation
94
if tooth can't be re-implanted immediately what need to be done
STORE tooth in appropriate medium HBBS, Egg White,Coconut Water,Milk, * Don’t let tooth dry out * Don’t re-implant a baby tooth
95
do you re-implant a baby tooth
no
96
storage medium time
dry <30min tap water 30-60min vestibule of mouth 90-120 min physiologic saline 90-120min cold milk 3h coconut water better than milk egg with +++ viaspan >24h
