  1. Author of article?
    Dr. Wim Laureys from Belgium
  2. Type of study?
    In-vivo study using 3 beagle dogs teeth
  3. Length of study?
    90 days
  4. How many teeth?
    15 teeth, single rooted, mature, incisors and first PM
  5. Method?
    extracted tooth, wire cutter apicoectomy (did not state how much of a resection) then reimplanted to original site, monitored for 90 days
  6. How did they record the new diameter of apex?
    Camera photography using a ruler, counted pixels within one mm and compared to pixels within the foramen
  7. How did they rate the amount of tissue infiltration?
    • 1. > 2/3 of the pulp chamber filled
    • 2. 1/3-2/3
    • 3. < 1/3
    • 4. no ingrowth
  8. Background
    Andreasen et al in 1990 monitored 370 autotransplanted teeth, found that those with a apex of less than 1mm had an 85% chance of losing vitality.

    Also, a pilot study using catheter tubes ranging from .6-1.5mm were placed into the alveolus of extracted teeth and new tissue was found to be ingrowing into the catheter tubes.
  9. Results:
    40% were in category 1, another 40% found in category two

    diameter apices .24-.53mm 5 teeth, category 1
  10. Discussion
    Size of foramen may not affect successfule revascularization

    Infraocclusion aids in pulp revascularization
