A similar systematic review published in 2009 suggested an overall success rate of 77.8% for surgical endodontic treatment at 2–4 years, falling to 71.8% at 4–6 years, and 62.9% at 6+ years. [8] There are many factors which will affect the likelihood of success of apicoectomy.
Success rates for root-canal treatment range from 47 to 97 percent; failures may be due to spaces in the root-canal filling, a root filling which is too short or a preexisting periapical lesion. [3] Treatment options are nonsurgical root-canal re-treatment or periradicular surgery.
A properly restored tooth following root canal therapy yields long-term success rates near 97%. In a large-scale study of over 1.6 million patients who had root canal therapy, 97% had retained their teeth 8 years following the procedure, with most untoward events, such as re-treatment, apical surgery or extraction, occurring during the first 3 ...
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. Instead, hydraulic (100% pure water) MTA shows the higher success rate than anti-washout gel or resin medium.
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.
Sharp, guillotine-type injuries with relatively uninjured surrounding tissue have the best post-replantation prognosis, with a success rate of 77%. [3] Severe crush injuries, multi-level injuries, and avulsion injuries often mangle soft tissue to the point of precluding rejoining of essential blood vessels, making replantation impossible. In ...
An apicoectomy is a surgical procedure through which the apex of a root is resected, and a root-end filling is placed, preventing bacterial leakage into the root canal system from the periradicular tissues. [14] A microsurgical technique is used to carry out apicectomy, which improves post-operative healing.
ABO-incompatible (ABOi) transplantation is a method of allocation in organ transplantation that permits more efficient use of available organs regardless of ABO blood type, which would otherwise be unavailable due to hyperacute rejection.
