Several studies have reported devitalization of teeth following surgical procedures in the area of the root apices. The purpose of this investigation was to observe the 1-4-week wound healing pattern in monkey dental tissues following @entity2045 ( @entity2045 ). Two adult @entity2608 were used in this study. All of the teeth were surgically transected within the apical one-third with a bur. The soft tissues were then closed. At @entity204 , a maxillary and a mandibular quadrant for 1, 2, 3 and 4 weeks following surgery were obtained after vascular perfusion. Each quadrant was demineralized in @entity1098 , processed, serially sectioned at 7 microns and alternately stained with @entity1710 and @entity1711 , Preece's modified trichome, and McKay's bacterial stains. Examination of sequential @entity2045 cuts showed an initial disruption of the @entity531 supply resulting in @entity39 . The pulpal tissues underwent a process of replacement with PDL-like connective tissues and deposition of cementum on all cut dentin surfaces of the tooth roots as well as in some of the pulp chambers. No abscesses, external resorption or @entity3947 were found.
