 note = {To improve the method of root canal filling, the authors performed a histopathological study using a novel system named the ‘simultaneously folded’ root canal filling method. This system calls for applying Vitapex paste near the area of the apical foramen followed by filling the remainder of the root canal by means of either the combination of gutta-percha point and KEZ endodontic cement (dry components: 40% zinc oxide, 20% calcium hydroxide, 20% iodoform and 20% rosin; liquid components: 90.5% eugenol 90.5%, 9.0% rosin and 0.5% setting agent) or Neodyne zinc-oxide eugenol cement. The authors compared the healing effects of this method with those resulting from a combined root canal filling method employing gutta-percha point and Neodyne endodontic cement. The root canals of 119 dog teeth were perforated by means of rotary cutting instruments. Pulp chambers were exposed and allowed to remain open for thirty days. Engine reamers were used to perforate the apical portions. They were cleaned with sodium hypochlorite and saline solutions. Fifty-one of the canals were filled using our ‘simultaneously folded’ technique with Vitapex, gutta-percha point and KEZ endodontic cement. Forty-two canals were filled using the 'simultaneously folded' technique with Vitapex, gutta-percha point and Neodyne. Twenty-six canals were filled using a combined root canal filling method with gutta-percha point and Neodyne. Three months later, the dogs were sacrificed and specimens were prepared for histopathological observation. Results showed that the ‘simultaneously folded’ root canal filling method resulted in a peculiar healing process featuring a cement barrier without ankylosis. Apparently, this method accelerated the closure of the apical foramen and regeneration of alveolar bone. Consequently, the 'simultaneous folded' root canal filling method is recommended for clinical application., Editor, Toshiyuki Kawakami, Language Editor, David M Carlson, viii, 232 p.  ill.
