Introduction: Endodontic instruments fracture is related to several factors from internal dental anatomy and type, to operator inability and inexperience. Objective: To review case reports related to fracture of endodontic instruments inside the root canal. Methodology: A literature review was carried out using papers available in the PubMed and Lilacs databases. Only case reports were included, with no restriction on language and publication year Results: It was analyzed eight papers with 11 instrument fracture cases, with the highest prevalence (45.5%) of rotary instruments fracture, occurring mainly in middle-cervical and middle-apical root canals thirds. In 90.9% of cases, techniques used for removal showed successful results and in only one case (9.1%), the technique was unsuccessful and the instrument was kept inside the root canal. Final considerations: Endodontic instruments fracture is a complication can directly affect prognosis and endodontic treatment success. Several techniques and devices can be used to remove fractured fragments inside root canals, however, there is no specific protocol for their removal.

ABSTRACT Aim This clinical report presents a rare case of maxillary central incisor with two separate roots. Background Unusual morphology of the roots and root canals may exist in any tooth. Recognition of the dental anatomy and its variations is necessary for successful endodontic therapy. It is well known that maxillary incisors are usually single-rooted teeth. Case report The root canals were instrumented with conventional hand files and Gates Glidden and obturated by using the lateral technique. Recall radiograph after 1 year shows the healing process of the preoperative apical periodontitis. Conclusion and clinical significance Clinicians should be aware of unexpected root canal morphology when performing root canal therapy. The present case demonstrated the importance of accurate preoperative radiograph and adequate access preparation. How to cite this article Maghsoudlou A, Jafarzadeh H, Forghani M.

Root Canal Morphology

Introduction. Predictable endodontic treatment depends on the dentist?s knowledge about root canal morphology and its possible anatomic variations. The majority of mandibular canines have one root and root canal, but 15% may have two canals and a smaller number may have two distinct roots. The following clinical reports describe endodontic treatment of mandibular canines with two roots and two root canals. Outline of Cases. Four clinical case reports are presented to exemplify anatomical variation in the human mandibular canine. Detailed analysis of the preoperative radiographs and careful examination of the pulp chamber floor detected the presence of two root canal orifices in all canines. Working length was determined with an electronic apex locator and biomechanical preparation was carried out by using engine driven BioRaCe Ni-Ti rotary instruments in a crown-down manner, followed by copious irrigation with 1% sodium hypochlorite. Definitive obturation was performed using cold lateral condensation with gutta-percha cones and Top Seal paste. The treatment outcome was evaluated using postoperative radiographs. Conclusion. Endodontists should be aware of anatomical variations of the treated teeth, and should never presume that canal systems are simple.

The Creation

Por meio deste estudo é possível analisar que a instrumentação dos canais radiculares após o uso do Glide Path traz inúmeros benefícios, incluindo o melhor deslizamento dos instrumentos, redução do número de fraturas e menor intercorrências intrarradiculares. Além disso, essa preparação inicial do canal radicular com o uso do Glide Path realiza uma desobstrução, criando um “caminho” livre para o melhor deslize dos instrumentos no canal radicular. Os instrumentos possuem características e particularidades que levam ao mesmo objetivo de preparar o conduto para uma segura instrumentação, destaca-se aqui o WaveOne Gold, R-Pilot e o PathFile. É uma técnica que vem sendo difundida e utilizada na endodontia contemporânea com o intuito de realizar um procedimento eficaz.---Abstract: Analyze the use of instruments to prepare the Glide Path and understand how this endodontic instrument brought advantages in instrumentation techniques. This is a literature review with selected articles from the last 10 years, in order to achieve the objectives proposed by the theme. Articles in English and Portuguese were used, with all information pertinent to the topic extracted. Through this study, it is possible to analyze that the instrumentation of root canals after the use of the Glide Path brings numerous benefits, including better sliding of the instruments, reduction in the number of fractures and less intra-radicular complications. In addition, this initial preparation of the root canal using the Glide Path performs clearance, creating a clear “path” for the best glide of the instruments in the root canal. The instruments have characteristics and particularities that lead to the same objective of preparing the conduit for safe instrumentation, the Wave One Gold, R-Pilot and PathFile stand out here. It is a technique that has been disseminated and used in contemporary endodontics with the aim of performing an effective procedure. Through this bibliographical study, it is possible to consider that the use of the Glide Path favors the preparation of the root canal and proves to be effective and safe when used before instrumentation, thus, with the creation of a more favorable environment for instrumentation, the chances of success in endodontic treatment.

Infected Root Canal

Instrument fracture is a serious complication during endodontic treatment of teeth, having an adverse effect on the outcome of the nickel titanium (NiTi) treatment, especially if the fracture prevents apical access to the infected root canal. Despite the advent of NiTi files, the risk of fracture during the endodontic preparation of root canals, especially in severely curved canals, remains a serious concern. The fracture of NiTi files during preparation may result in a compromised prognosis for the tooth. In the presence of periapical lesions, instrument fracture may reduce the chances of successful healing.

The most important requirements for successful endodontic treatment are accurate diagnosis and good knowledge of canal morphology. A mandibular second premolars rarely have more than one root and one root canal. Data from the literature indicate low percentage of a mandibular premolars with three or more root canals. Unusual morphology of the root canal system is diagnostic and therapeutic challenge. It is very important to analyze preoperative radiograph and to explore thoroughly the entrance of the root canal. The aim of this study was to present two patients who had lower second premolars with three canals that required endodontic therapy.

Root Fractures

Evidence indicates that root canal preparation is a critical step upon which the prognosis of the endodontic treatment depends. Vertical root fractures can furtherly develop as propagations from the previously formed dentin cracks. Therefore, root canal preparation should be carefully approached with the minimal crack formation and careful dentin removal. Different modalities have been proposed in the literature and rotary systems are most commonly used nowadays. Although the reported efficacy of these modalities is high, evidence shows that they are usually associated with a considerable risk of crack formation. In the present literature review, we have discussed the effects of rotary instrumentation and root canal preparation on dentinal crack formation based on evidence from the different studies in the literature. Our evidence showed that all of the investigated approaches to prepare root canals adequately can result in crack formation. The different rotary instrumentations also showed variable frequencies of developing dentinal cracks, and evidence from some comparative investigations shows that ProTaper modalities are associated with the least frequencies of the events. However, to make a solid conclusion for clinical practice, further research is still needed to validate our current evidence.

Cleaning And Disinfection

Ultrasonic tips and anatomic finishing files have been used as strategies to improve the cleaning and disinfection of root canals, especially in complex anatomies. These instruments are also subjected to fractures, which can hinder the endodontic treatment and negatively affect the outcome. This article presents two cases of successful management of intracanal-fractured instruments with unfavourable prognosis, emphasizing on treatment protocols and outcomes. Two 14-year-old female patients underwent root canal treatment of teeth 37 (case 1) and 47 (case 2). During the final irrigation protocols, case 1 presented a fractured XP-Clean file within the mesiobuccal canal and within the distal canal in case 2, which also showed fractured E1-Irrisonic tips within the mesiobuccal and distal canals. Non-surgical management and bypassing retained instrument fragments were successful in both cases and they may be considered adequate approaches.

Endodontic treatment of the teeth with severe root canal curvatures has become one of the greatest problems in clinical practice. Recently, new instruments and techniques have been introduced in the endodontic procedure. The aim of this study was, on the basis of clinical practice, to show the possibilities of the endodontic treatment in the teeth with severely curved root canals, after dependable decision about endodontic instruments and techniques. This article presents a complete endodontic procedure in two teeth with different curvature shape of the root canal in patients that were treated at the Department of Restorative Dentistry and Endodontics, School of Dentistry, Belgrade. Coronal to apical 'crown down' technique was used for the root canal preparation with hand NiTi ProTaper instruments with progressive multicone design. The main reasons for choosing manual technique were complexity, shape of presented curvatures and better tactile sensation control of canal instruments in order to avoid possible mistakes and complications. Clinical X-rays of the teeth with permanent obturation clearly showed that extremes of the root canal morphology could be successfully solved by the right choice of all factors during endodontic procedure.
