A 17 year old male presents 20 minutes after having his tooth knocked out during a hockey game brawl. His parents preserved the tooth wrapped in a dry paper towel. He denies loss of consciousness or vomiting. Vitals are within normal limits. Exam shows a well-appearing male in no apparent distress with loss of tooth #8. The tooth socket is hemostatic, and there is no deformity or tenderness to palpation. The tooth is irrigated, replanted, and splinted. Which of the following is indicated at this time?
|A||calcium hydroxide paste|
|B||consult oral maxillofacial surgery|
|C||CT facial bones|
This patient experienced a tooth avulsion with subsequent ED replantation. Notably, time to replantation is the most important prognostic factor. Doxycycline has also demonstrated some benefit in successful replantation of the tooth. Calcium hydroxide paste is used in dental fractures, not avulsions. Consulting oral maxillofacial surgery is not necessary after ED replantation, but the patient should have expedited dental follow up. CT facial bones will unlikely show an acute fracture given the patient has no clinical findings to suggest injury. A panoramic x-ray may be beneficial in confirming tooth position after replantation.
|Time is tooth! |
Rule of thumb: each minute = 1% lower chance of successful replantation
Transport solutions: Hank solution > milk > saliva > saline
Handle by crown, irrigate gently with saline (do not disrupt periodontal ligament fibers)
Pain control, manual pressure, splint
