OBJECTIVE: The objective of this study was to evaluate in vivo the revascularization and the
apical and periapical repair after endodontic treatment using 2 techniques for root canal
disinfection (apical negative pressure irrigation versus apical positive pressure irrigation
plus triantibiotic intracanal dressing) in immature dogs' teeth with apical periodontitis.
STUDY DESIGN: Two test groups of canals with experimentally induced apical periodontitis
were evaluated according to the disinfection technique: Group 1, apical negative pressure …
