After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
The step back technique, also known as telescopic or serial root canal preparation, is divided in two phases: in the first, the working length is established and then the apical part of the canal is delicately shaped since a size 25 K-file reaches the working length; in the second, the remaining canal is prepared with manual or rotating ...
A root end surgery, also known as apicoectomy (apico-+ -ectomy), apicectomy (apic-+ -ectomy), retrograde root canal treatment (c.f. orthograde root canal treatment) or root-end filling, is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material.
The filling promotes cementum and bone formation, [21] [22] blocks bacteria, and is a barrier for the root canal. Inflammation of the periradicular site due to bacteria could cause recovery to deteriorate and induce periradicular infection. [22] Careful evaluation of root canal filling material is required to optimise healing after the procedure.
"Temporomandibular Pain and Dysfunction Syndrome – Aching in the muscles of mastication, sometimes with an occasional brief severe pain on chewing, often associated with restricted jaw movement and clicking or popping sounds." (Classification of Chronic Pain, International Association for the Study of Pain). [20]
Procedures for root canal. The space inside the root canals is filled with a highly vascularized, loose connective tissue, called dental pulp. The dental pulp is the tissue of which the dentin portion of the tooth is composed. The dental pulp helps complete formation of the secondary teeth (adult teeth) one to two years after eruption into the ...
Regenerative endodontics has 3 critical steps: adequate disinfection of the root canal system, induction of bleeding through overinstrumentation to create a scaffold for stem cells, and coronal sealing of the blood clot with a biocompatible material, such as mineral trioxide aggregate. The procedure is applied in two visits as follows: [50]
Miscellaneous endodontic instruments. From left: Lentulo spiral, reamer, K-file and H-file. Hand files can provide tactile sensation when cleaning or shaping root canals. This allows the dentist to feel changes in resistance or angulation, which can help determine curvature, calcification and/or changes in anatomy, in which two dimensional radiographs may not always identif
