An apicoectomy is necessary when conventional root canal therapy has failed and a re-treatment was already unsuccessful or is not advised. [1] Removal of the root tip is indicated to remove the entire apical delta ensuring no uncleaned missed anatomy.
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
An x-ray of a root canal operation. Before endodontic therapy is carried out, a correct diagnosis of the dental pulp and the surrounding periapical tissues is required. This allows the endodontist to choose the most appropriate treatment option, allowing preservation and longevity of the tooth and surrounding tissues.
In 1890, W.D. Miller, considered the father of oral microbiology, was the first to associate pulpal disease with the presence of bacteria. [11] This was confirmed by Kakehashi, who, in 1965, proved that bacteria were the cause of pulpal and periradicular disease in studies using animal models; pulpal exposures were initiated in both normal and germ-free rats, and while no pathologic changes ...
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.
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.
It contrasts with root resection, where a root is removed while leaving the crown intact, and an apicoectomy, where only the tip of the root is removed. [1] A hemisection is only performed on molars, which have 2 to 3 roots. Incisors, canines, and lower premolars only have 1 root each.
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.
