Pulpal and periapical tissue reactions after experimental pulpal exposure in rats.

abstract：INTRODUCTION:The purpose of this in-depth investigation was to identify, clarify, and substantiate clinical terminology relative to apical/periapical/periradicular diagnostic states, which is used routinely in the provision of endodontic care. Furthermore, the information gleaned from this investigation was used to lin...
