The pulp contains blood vessels, nerves and connective tissue, and creates the physiology and pathology of the human dental pulp and periradicular tissues.
This includes teeth with irreversibly inflamed and infected pulpal tissue. Not only does endodontics involve treatment when a dental pulp is present, but also includes preserving teeth which have failed to respond to non-surgical endodontic treatment, or for teeth that have developed new lesions, e.g., when root canal re-treatment is required, or periradicular surgery .
Where visualisation of the periradicular tissues and tooth root is required when perforation or root fracture is suspected. 5. Where it may not be expedient to undertake pro-longed nonsurgical root canal retreatment because of patient considerations. Contraindications to surgical endodontics 2021-02-17 · Endodontists deal with the dental pulp and periradicular tissues, which are the blood vessels, tissues, and nerves surrounding a tooth’s root. They are highly trained in performing root canals and surgeries for dental pulp diseases.
5 Pain occur due to diseases involving pulp and periradicular tissues, as this tissues are richly innervated and have ample of blood supply. Also it is enclosed by surrounding tissues that are 30 • 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 the periradicular tissues is 2.58 mg, while using NiTi rotational mechanical instruments with crown-down technique it is less than 0,5 mg (10). While perform-ing the chemomechanical preparation of root canal it is essential to reach the end point of root canal which is the physiological apex of the root – the conjunction of cementum and dentine. 2014-09-01 · 47. The periradicular tissues consist of the cementum, which covers the roots of the teeth, the alveolar process which forms the bony troughs containing the roots of the teeth, and the periodontal ligament whose collagen fibers, embedded in the cementum of the roots and in the alveolar process, attach the roots to the surrounding tissues.

periradicular tissues; and periradicular inflammation can be observed even before the entire root canal becomes necrotic. 42,43 As the infection progresses, the cellular infiltrate intensifies and tissue destruction continues with the formation of small abscesses and necrotic foci in the pulp, which eventually leads to total pulp necrosis.44
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. tissue compartments, which coalesce and move to-wards the apical part of the canal until virtually the entire root canal is necrotic and infected. At this stage, involved bacteria can be regarded as the early root canal colonizers or pioneer species. Bacteria colonizing the necrotic root canal start inducing damage to the periradicular tissues Acute inflammation of the periradicular tissues (such as in acute apical abscess, acute periradicular periodontitis, and so on) is characterized by a reduction in mechanical pain thresholds presumably because of peripheral (e.g., sensitization of nociceptors innervating the periodontal ligament) or central (e.g., central sensitization) mechanisms. Describe the structure and function of the periradicular tissues. The dental pulp is the loose connective tissue in the center of the tooth. The primary function of the pulp is to form and support the dentin that surrounds it and forms the bulk of the tooth.
Its main purpose is to remove pathological periradicular tissues for visibility and accessibility to facilitate the treatment of the apical root canal system, or sometimes for the removal of harmful foreign materials present in the periradicular area. Prevention or treatment of apical periodontitis is aimed at disinfecting the root canal system so that the periradicular tissues are not vulnerable to attack from microbiota within the tooth. This is achieved by a process of cleaning and shaping the root canal space. The fundamental principles underlying this process have not changed in decades. The periradicular tissue comprises of surroundin Alveolar bone, periodontal ligament & cementum.

Reversible pulpitis. This paper critically reviews the effects of intra‐canal procedures on the periradicular tissues, with special emphasis on the occurrence of post‐operative pain and the outcome of the root canal treatment. The possible systemic effects stemming from root canal procedures are also discussed in the light of current knowledge. (periradicular) Abscess Acute Apical Abscess.
