A
  • it is likely that the damage to the PDL cells are minimal so high chance of PDL healing
  • in open apex teeth, also chance of pulp revascularisation so no endo tx unless signs of necrosis
    1. leave tooth in situ
    2. apply LA, clean area and suture any lacerations
    3. verify position w xray
    4. apply flexible splint 2wks
