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.
Periradicular surgery should be very considered where previous endodontic treatment has failed, and possible re-root treatment is the preferred option. [4] If re-root treatment is not possible, will not correct the problem or patient factors prevent it, periradicular surgery is indicated.
Periradicular surgeries involve the root surface. These include apicoectomy (removal of a root end), root resection (removal of an entire root), repair of an injured root due to perforation or resorption, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
Apicoectomy is the surgical removal of tooth's root tip. Appendectomy is the surgical removal of the appendix; it is also known as an appendicectomy. Arthrectomy is the removal of a joint of the body. Atherectomy is a removal of atherosclerosis. Auriculectomy is the removal of the ear.
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown Removing infected pulp during a root canal procedure
Root resection or root amputation is a type of periradicular surgery in which an entire root of a multiroot tooth is removed. It contrasts with an apicoectomy, where only the tip of the root is removed, and hemisection, where a root and its overlying portion of the crown are separated from the rest of the tooth, and optionally removed.
MTA Plus material is also indicated for base and liner in vital pulp therapy. In root-end filling after apicoectomy, the anti-washout agent (chitosan or gelatin) is useful to prevent from MTA washout. But in vital pulp therapy, anti-washout gel doesn't increase bioactivity or bacterial tight sealing ability of MTA.
Use of barrier membranes to direct bone regeneration was first described in the context of orthopaedic research 1959. [2] The theoretical principles basic to guided tissue regeneration were developed by Melcher in 1976, who outlined the necessity of excluding unwanted cell lines from healing sites to allow growth of desired tissues.
