The tissues wounded in periradicular surgery are the mu- coperiosteal tissues (gingiva, alveolar mucosa, palatal mucosa, and underlying periosteum), periradicular tissues (bone, gin- gival ligament, and periodontal ligament), and radicular tis- sues (cementum and dentin). These tissues, with the exception

• Periradicular tissue consists of root cementum,periodontal ligament and the alveolar bone. The apical periodontium is highly cellular structure enriched with blood and lymphatics as well as

Also it is enclosed by surrounding tissues that are With vital pulps, periapical tissues are normal and can be maintained with an aseptic technique, confining preparation and filling procedures to the canal space. Infected nonvital pulps with periapical pathosis must have this process altered in favor of the host tissue, and repair is determined by the ability of this tissue to respond. This paper will present the tissue responses to trauma under the tissue compartments typically involved following dental trauma: the pulp, the periradicular tissues (including the periodontal ligament and alveolar bone), and their interaction with the injured root in teeth with complete or incomplete root development, as well as the associated soft tissues (including gingiva and marginal periodontium). One of the strongest factors contributing to the controversies often encountered in the endodontic field is the lack of understanding that the disease processes of the pulp and periradicular tissues generally have a microbiological etiology.

Acute Periradicular Periodontitis - Acute periradicular periodontitis occurs when pulpal disease extends into the surrounding periradicular tissues and causes inflammation. periodontal disease (Gustkeet al ., 1998), its effects on periradicular tissue, which differs structurally from marginal periodontal tissue, are not known. Rats with spontaneous or type 2 diabetes have been generated by selective breeding of normal rats with impaired glucose tolerance (Gotoet 2013-08-01 Root canal obturation prevents channel of fluids from the periradicular tissues into the canal as well as microorganisms and their virulent by-products from the canal to the periradicular tissues. Canal irregularities, accessory canals, discrepancies between the filling materials, and the canal walls are expected to be filled by the sealer. More periradicular dentin is laid down often completely occluding the dential tubules in the periphery ( sclerotic dentin).permeability is reduced Pulp tissue becomes less cellular and less vascular and contains fewer nerve fibers Between the ages of 20 and 70, cell density decreases by approximately 50%.

Pathological changes in the pulp and periradicular tissues are due to microorganisms and their byproducts. To achieve optimal healing of periradicular tissue

Radiographically, periradicular tissues are normal with an intact lamina dura and a uniform periodontal ligament (PDL) space. Acute Periradicular Periodontitis - Acute periradicular periodontitis occurs when pulpal disease extends into the surrounding periradicular tissues and causes inflammation. periodontal disease (Gustkeet al ., 1998), its effects on periradicular tissue, which differs structurally from marginal periodontal tissue, are not known. Rats with spontaneous or type 2 diabetes have been generated by selective breeding of normal rats with impaired glucose tolerance (Gotoet 2013-08-01 Root canal obturation prevents channel of fluids from the periradicular tissues into the canal as well as microorganisms and their virulent by-products from the canal to the periradicular tissues.

2015-09-01 · The response of the periradicular tissues to various injuries is similar to that of other connective tissues elsewhere in the body. Bacteria exert their pathogenicity by wreaking havoc on the host tissue through their toxins (lipopolysaccharides, lipoteichoic acid, peptidoglycans, etc.,), noxious metabolic byproducts, secreted products such as enzymes and heat shock proteins.[ 37 ] Sections from 19 periradicular granulomas and pulp tissues from two healthy control teeth were examined using the immunohistochemical method.

More periradicular dentin is laid down often completely occluding the dential tubules in the periphery ( sclerotic dentin).permeability is reduced Pulp tissue becomes less cellular and less vascular and contains fewer nerve fibers Between the ages of 20 and 70, cell density decreases by approximately 50%. (periradicular) Abscess Acute Apical Abscess. An inflammatory reaction to pulpal infection and necrosis. characterized by rapid onset, spontaneous pain, tenderness of the tooth to pressure, pus formation and swelling of associated tissues. In a number of periradicular tissues [6, 7]. As a root canal filling material, cases, several factors such as a complex root canal system or MTA has proved successful [8, 9]; comparative studies with previous procedural accidents may impede the success of other root canal filling materials have shown less leakage as nonsurgical retreatment.
