| Research Abstract |
Summary : Our study suggested that, in laser treatment of the pulp canal, 8. 77 J/cm^2 is sufficient to remove infected dentin. In terms of manipulator design, a prototype was produced by making longitudinal openings in a stainless steel tube in four directions and inserting a total of six 1-mm-diameter glass balls. This configuration made it possible to irradiate the pulp canal wall with the laser. Laser irradiation was particularly high in the upper portion and low in the lower portion, which is appropriate for actual pulp canal treatment.
