This article reported two clinical cases in which the guided endodontics was used to perform the access to the root canals. The first case presents a 40-year-old female with a history of pain related to the left maxillary canine. After radiographic examination, the presence of severe calcification up to the apical third of the root canal, associated with a periapical radiolucency, was noted. In the second case, an 85-year-old male was referred to our service with pain upon palpation, at the right mandibular first molar. The radiographic images revealed the presence of endodontic treatment and a fiberglass post in the distal root canal, which was associated with extrusion of the filling material and a periapical lesion. The 3D-guides were planned based on cone beam computed tomography and intraoral digital scanning, which were aligned using a specific software. Therefore, implant drills could be guided up to the root canal length required for each case. In the first case, a surgical root canal was created and the patient was free of signs and symptoms after the treatment was completed. In the second case, it was observed that the fiber post was worn by the drill, allowing free access to the filling material. It was possible to perform the endodontic reintervention in a more predictable way and in less time. In both cases, the use of the guided endodontics allowed the preservation of a large part of the dental structure. The procedures were performed faster, without the occurrence of fractures and perforations.
In recent years, cone beam computed tomography (CBCT) has become much more widely available and utilised in all aspects of dentistry, including endodontics. Cone Beam Computed Tomography in Endodontics is designed to inform readers about the appropriate use of CBCT in endodontics, and enhance their clinical practice with this exciting imaging modality.
This book begins with a concise review of the basic science of tissues and then moves into diagnosis, treatment planning, and surgical procedures in endodontics, with an emphasis on the use of enhanced magnification, ultrasonic tips, microinstruments, newer root-end filling materials, and CBCT. Chapters on the maxillary sinus and its relation to surgical endodontics, soft and hard tissue healing, and adjunctive surgical procedures and considerations such as management of procedural accidents, resorption, root amputation, hemisection, replantation, transplantation, crown lengthening, grafting materials, and pharmacology are followed by an assessment of the outcomes of surgical endodontics based on current evidence. The accompanying DVDs present valuable videos demonstrating many of the procedures. These features provide the reader with a textbook that is concise, current, and easy to follow in an interactive manner. Written by a team of leading authorities and richly illustrated, this new compendium of state-of-the-art knowledge and protocols is essential reading for practicing endodontists and residents alike.
Subjects entering the model were smokers with periodontitis. Some subjects were supposed to receive SCT and others not. In both cases, they could stop smoking or not. All subjects received non-surgical periodontal treatment (six sessions of scaling and root planning) and one session of maintenance therapy (one session of scaling and root planning). In the decision-analytic modeling framework, this stage was represented as a simple decision tree. We did not consider the possibility of relapsing smoking and/or need of reintervention with SCT.

Relevant articles had been read and assessed by the introduction of the close meaning ideas by the study reviewers. Full articles were obtained for most of the titles and abstracts that met the inclusion criteria, the full text was accessed. From each included article, study design, interventions, and findings were extracted. Articles used were categorized into two main groups (free and restricted). Free ones have been downloaded directly by the URLs generated from the database. The restricted group has been downloaded by the institutional access of the King Abdulaziz University (KAU) library. Even though some articles did not match the main idea, they have been reviewed again & decided to be either relevant or irrelevant.
The objective of this study was to systematically review the literature about the use of the operating microscope in endodontics. It used sources of bibliographic cataloging electronically identified by MEDLINE via PubMed, LILACS, BBO and Scopus, using as descriptors: Endodontics, anatomy and microscopy. The selected articles were identified from the titles and abstracts, taking into consideration the following criteria: publications ranging from January 2001 to November 2012, case reports, published in an indexed journal, and publications in English language. The search showed 167 articles related to this topic, and these 21 articles met the inclusion criteria. These indicated that a higher magnification helps coronary access and the location of channels to identify and interpret the complexities of the anatomy of root canals, the removal of nuclei and intracoronary fractured instruments, to minimize trauma of surgeries in soft and hard tissues, and detect fractures and microfractures. It was found that its use has provided Endodontics with a significant improvement in vision of the operative field, offering better quality jobs and a higher success rate.
The OM Endodontics was introduced in the early 1990s by Gary Carr [3], and their study was the basis for several other authors deepen research on its use in Odontology [2]. Its incorporation in that specialty had profound effects on how to work the endodontist; For this reason, in 1998 the American Dental Association has requested that all graduate programs in the United States should teach the use of the microscope in nonsurgical and surgical endodontics [4].
After analyzing the twenty-one items selected, it was observed that there was an increase in the number of publications in 2011 and 2012, of four jobs each year. This fact may be related to increased acquisition of this equipment by specialists in endodontics, contributing to a greater number of publications.
When there is a deficiency in some stage of endodontic treatment is required reintervention [1]. One of the selected articles reported retreatment of upper and lower first molars, describing that the microscopic analysis was more effective in detecting and removing debris, but also allowed the location of additional channels [8]. In two other studies conducted in the upper anterior teeth the operating microscope was used for retreatment of dens invaginatus and perforation closure [16,29].
Non-surgical endodontic retreatment should always be the first option for reintervention when the initial endodontic treatment fails. The surgical treatment, called periradicular surgery, will be the procedure of choice when there is no success after the conventional endodontic retreatment. The purpose of this article is to describe clinical case of endodontic surgery, associated with guided tissue regeneration (GTR). A male patient, 24 years old, was referred for endodontic surgery on tooth 12 after two unsuccessful endodontic interventions. During the surgery, osteotomy, lesion curettage, apicectomy, retrograde obturation with Mineral Trioxide Aggregate (MTA), and filling of the bone failure with lyophilized bone and reabsorbable collagen membrane were performed. After six months of follow-up, the patient did not present any type of painful symptomatology. The endodontic surgery, associated with a technique of guided tissue regeneration, was efficient to solve this clinical case. 153554b96e
