This study examined histologically the effect of three sealers used with gutta‐percha as root‐end fillings placed in a replantation model. A total of 14 molar teeth were used in seven monkeys. Alter extraction, root ends were resected, the canals contaminated with oral bacteria, root‐end cavities prepared, and fillings of gutta‐percha and sealer placed prior to replantation. After 8 weeks the teeth and surrounding Jaw were removed and prepared for histological examination. Six roots filled with gutta‐percha plus a fortified zinc oxide‐eugenol cement (IRM). 13 With gutta‐percha plus zinc oxide‐eugenol (EP), and eight with gutta‐percha pins Kloropercha. were available for examination. The tissue response to gutta‐percha with either Zinc oxide material was characterized by little or no inflammation of limited extent. In contrast, more severe inflammation was observed against root ends filled with gutta‐percha and Kloropercha. Gutta‐percha plus IRM or Zinc oxide‐eugenol had a much more favourable response than that to amalgam reported previously in a similar experiment.
