The effect of the filling material in the tissue reactions following apical plugging of the root canal with dentin chips. A histologic study in monkeys' teeth

The object of the present work was to observe whether the root canal filling material has some influence in the periapical healing process after apical plugging with dentin chips. Monkeys' teeth were filled with nine different filling materials in use today. Ninety days after the treatment, the histologic data showed no differences in the results with the nine materials studied. This fact suggests that the filling material does not influence the healing process when the plug is present. © 1983.
