Presentation Transcript

  1. Avulsions

  2. Avulsion • Quick emergency intervention • Urgent clinical treatment • Multidisciplinary nature

  3. Accident Site • Replant if possible or place in appropriate storage medium to minimize necrosis of PDL cells • Storage media in order of preference, Hank’s balanced salt solution, milk, saliva, saline or water. Water is better then dry but is hypotonic and rapid cell lysis, death and resulting inflammation. • Single most important factor is speedy replantation, make effort to replant with in 20 minutes.

  4. Dental Office • Prepare the socket • Prepare the root • Replant • Construct splint • Administer local or systemic antibiotics

  5. Preparation of the RootExtraoral dry time less then 60 minutes • Closed apex: rinse root with saline and replant gently. Pulp will die but if replanted within 20 minutes a good chance of PDL healing exists. Over 60 minutes periodontal cell survival is unlikely. • Open apex: gently rinse off debris with saline, soak in doxycycline for 5 minutes. This enhances pulpal revascularization. (1 mg in 20 ml of saline)

  6. Preparation of the Rootextraoral dry time exceeds 60 minutes • Closed Apex: remove entire PDL by placing in acid, rinse with saline and soak in 2% stannous fluoride for five minutes, replant. • Open Apex: Controversy regarding replanting. Is yes same as above but definitely do endodontics extraorally to facilitate the seal. Will be lost do to osseous replacement resorption but will maintain height and width of alveolar bone

  7. Preparation of the Socket • Leave undisturbed before replantation • If an organized clot is blocking replantation gently rinse with saline and lightly aspirate • If alveolar bone has collapsed use a blunt instrument to reposition the wall

  8. Splinting • Splint should allow some movement to stimulate PDL fibers to reattach. A rigid splint promotes ankylosis • Physiologic splint removed in 2 weeks • Make sure the repositioned tooth and splint are not in traumatic occlusion. • Remember if the avulsed tooth occurs in conjunction with an alveolar fracture splint must remain for 4 to 8 weeks

  9. Adjunctive Therapy • Begin antibiotics from day of replantation until splint removal. • For patients not susceptible to tetracycline staining use doxycycline (decreases resorption) or Pen VK • Gentle oral hygiene and chlorhexidine rinses • Pain relieve usually NSAI if needed

  10. Endodontic Treatment • Extraoral time less than 60 minutes with closed apex: Initiate endodontic after 2 weeks use long term CAOH before obturation to inhibit resorption • Opened apex less than 60 minutes: Avoid endodontic treatment, look for signs of revascularization. Follow closely at first sign of infection initiate apexification procedures.

  11. Endodontic Treatment • Extraoral time more than 60 minutes with closed apex: Initiate endodontic therapy after 2 weeks, use long term CAOH treatment • More than 60 minutes and an open apex: do the endodontics outside the mouth before replanting. If it was replanted without an obturation initiate apexification. Remember some would suggest not replanting because of certain replacement resorption
