It has been determined that a measure of the therapeutic success of pulpotomy is the preservation of the majority of the root pulp, the absence of pain and signs of inflammation; the periradicular
tissue is alive and healthy; there are no radiological signs, i.
Frequency and type of canal isthmuses in first molars detected by endoscopic inspection during periradicular
Immature teeth with periradicular
periodontitis or abscess undergoing apexogenesis: a paradigm shift.
Inflammatory infiltrate of chronic periradicular
lesions: an immunohistochemical study.
The uncleaned and unfilled root canal system was still infected and the colonisation of mixed microorganism formed bacteria biofilm which elevated their virulence and caused periradicular
Mucosal fenestration can be caused due to malpositioning of teeth, prominent morphology of the root apex, thin alveolar cortex or severe periradicular
inflammation with bone destruction.
tissue response to mineral trioxide aggregate (MTA) as root-end filling material.
Removal of the filling material is one of the critical points of endodontic retreatment because filling remnants adhered to the dentinal walls may harbor microorganisms and necrotic tissue residue that lead to persistence of periradicular
During the retreatment procedures, dentin chips, filling materials, microorganisms, and/or irrigants may be extruded from the root canal space into the periradicular
Lumbosacral herniated discs: Chemodiscolysis with nucleophthesis with O2-O3 and periradicular
and periganglionic infiltration under CT guidance personal experience.
It is possible to achieve improvement in periradicular
tissues after the appearance of a periapical granulomatous lesion as in the case reported.
Volatile compounds like phenols and aldehydes are reported as potential carcinogens (20-22), aldehydes & halides are reported to produce periradicular
tissue toxin (22) and calcium hydroxide one of the most commonly used intra-canal medicament now a days is reported to be ineffective against E.
