PDL Injuries Revision Questions Flashcards
Concussion
Injjury to tooth supporting structures without increased mobility, displacement of tooth or ging bleeding Pain on percussion Sens may be negative No increased mobility TTP = yes
Treatment for concussion
No treatment required just observation
Exercise care when eating not to further traumatise area
Instruct OH with CHX and gentle brushing x2 a day for 1 week
soft diet
Follow up - 1 week, 6-8weeks, monitor pulp for 1 year
Subluxation
Trauamtic injury occured to perio tissues leading to increased mobility but no displacement
TTP = yes
No damage to follice or permanenet tooth germ
Subluxation
Trauamtic injury occured to perio tissues leading to increased mobility but no displacement
TTP = yes
No damage to follice or permanenet tooth germ
Treatment for subluxation?
Can provide a fleixble splint for 2 weeks
Follow up - 2,4,6-8, and 1 yeae, monitor pulp status for 1 year
Treatment for subluxation?
Can provide a fleixble splint for 2 weeks
Follow up - 2,4,6-8, and 1 yeae, monitor pulp status for 1 year
Extrusion
Partial or total seperation of the perio ligament resulting in displacement of tooth out of the socket
Alveolar socket remains intact
Tooth will ususally have some protrusive or retrusive orientation
Seperation of perio ligament and coronal exposure of root surface
Appears elongated
TTP = yes and mobile
Treatment for extrusion
Reposition under LA
Flexible splint for 2 weeks
Follow up - 4,6-8,6months and yearly for 5 years
Lateral luxation injury
displacement of a tooth other than axially and accompained by communication or fracture of either the labial or palatal/lingual bone
Partial or total seperation of perio ligament
PDL has suffered both tearing and crushing injuries
Usually non mobile and gives a high metallix ankylotic sound
Treatment for lateral luxation
Reposition under LA
Flexible splint for 4 weeks
Follow up - 4,6-8,6 months, yearly for 5 years
Intrusion injury
Tooth has been driven into the alveolar process due to an anxially direct impact
Likely to occur in teeth with fully developed roots
Crushing injury to PDL
damage to permanent tooth
tooth non mobile and gives high metallic sound
Treatment for intrusion injury
incomplete root formation - spontaneuous tooth repositioning, advise re-diet and OH, review monthly to obeserve, re-eruption - splint for 4 weeks
Complete root formation - <3mm allow for re-eruption - if no eruption at 8 weeks then surgical repositioning and plint
3-7mm - reposition surgically
>7mm - surgical repositioning, pulp death likely so start RCT at 2 weeks, use intra canal medicament to prevent external resorption
Dental alveolar fracture
damage to the alveolar bone, multiple teeth moving as a unit
Treatment for dental alveolar fracture
Flexible splint for 4 weeks and antibiotics may be needed
Soft diet for 7 days and avoid contact sport while splint is in place
Careful OH with use of CHX mw
Follow up - 2,4,8, 4months, 6 months, 1 year and yearly for 5years
Oral hygiene advice for flexible splint
Dont brush for first day
Use soft brush after this
CHX mw for 7 days
Soft diet and avoid contact sports
