Background Reciproc instruments are the only contemporary root canal instruments where glide path preparation is no longer strictly demanded by the manufacturer. As the complete preparation of root canals is associated with success in endodontic treatment we wanted to assess the ability and find predictors for Reciproc instruments to reach full working length (RFWL) in root canals of maxillary molars in primary root canal treatment (1°RCTx) and retreatment (2°RCTx) cases. Methods This retrospective study evaluated 255 endodontic treatment cases of maxillary molars. 180 were 1°RCTx and 75 2°RCTx. All root canals were prepared with Reciproc instruments. The groups were compared and in a binary logistic regression model predictors for RFWL were evaluated. Results A total of 926 root canals were treated with Reciproc without glide path preparation. This was possible in 885 canals (95.6%). In 1°RCTx cases 625 of 649 (96.3%) canals were RFWL and in 2°RCTx cases 260 of 277 (93.9%). In second and third mesiobuccal canals (MB2/3) 90 out of 101 (89.1%) were RFWL with Reciproc in 1°RCTx and in the 2°RCTx treatment group 49 out of 51 cases (96.1%). In mesio-buccal (MB1) canals “2°RCTx” was identified as negative predictor for RFWL (OR 0.24 (CI [0.08–0.77])). In MB2/3 canals full working length was reached less often (OR 0.04 (CI [0.01–0.31])) if the tooth was constricted and more often if MB2/3 and MB1 canals were convergent (OR 4.60 (CI [1.07–19.61])). Discussion Using Reciproc instruments, the vast majority of root canals in primary treatment and retreatment cases can be prepared without glide path preparation.

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.

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.

Cleaning Efficacy

INTRODUCTION AND OBJECTIVE: The aim of this study was to evaluate the ability of root canal cleaning of the RaCe rotary instrumentation system (FKG Dentaire - La-Cheaux-de Fonds - Switzerland), compared to manual filing with Stainless Steel K-files (Maillefer Instruments - Ballaigues - Switzerland). MATERIAL AND METHOD: Twenty extracted human teeth (maxillary molars) were selected and their pulp tissue was removed after coronal access. The root canals were filled with a dye (India ink) and allowed to dry for 48 hours, followed by establishment of the working length of the mesiobuccal root; then, half of the specimens were instrumented by the modified Oregon technique and the other half were instrumented by crown-down sequence of the RaCe system. After preparation, the teeth were longitudinally sectioned and evaluated according to the amount of remaining dye. RESULTS: Data obtained were registered as numerical scores, and the arithmetic means were compared between groups using the Mann Whitney test. Both techniques were unable to completely clean the interior of the root canals, with a better performance of the manual technique only at the middle third. CONCLUSION: It could be concluded that the RaCe system was able to provide satisfactory cleaning, similar to that obtained by the manual instrumentation technique.

Radiographic Interpretation

INTRODUCTION Taurodontism is a morphoanatomical change in the shape of a tooth. An enlarged body of a tooth with smaller than usual roots is a characteristic feature. Internal tooth anatomy correlates with this appearance, which means that a taurodontal tooth has a large pulp chamber and apically positioned furcations. This dental anomaly may be associated with different syndromes and congenital discoders. CASE OUTLINE The case report presents the patient of a rare case of taurodontism in the mandibular second premolar with chronic periodontitis. Endodontic treatment was performed after dental history and clinical examination. Special care is required in all segments of endodontic treatment of a taurodontal tooth from the identification orifice, canal exploration, determining working length, cleaning and shaping and obturation of the root canal. Precurved K-file was used for canal exploration and location of the furcation. One mesial and one distal canal with the buccal position were identified in the apical third of the root canal. The working lengths of two canals were determined by radiographic interpretation with two K-files in each canal and verified with the apex locator. During canal instrumentation, the third canal was located in the disto-lingual position. The working length of the third canal was established using the apex locator. CONCLUSION Thorough knowledge of tooth anatomy and its variations can lead to lower percentage of endodontic failure. Each clinical case involving these teeth should be investigated carefully, clinically and radiographically to detect additional root canals. High quality radiographs from different angles and proper instrumentarium improve the quality of endodontic procedure.

Background.This study purposed to compare the effect of new single glide path files on extruded apical debris and total preparation times during root canal preparation with the WaveOne Gold system. Methods. Thirty-six extracted human lower molar teeth with mesiobuccal canal curvature angles of 25‒35° were randomly splited to three groups. In group 1, the glide path was created with WaveOne Gold Glider (WGG) file at working length (WL); in group 2, the glide path was created with ProGlider file (PG); in group 3, the glide path was not performed. In all the groups, the root canals were shaped with WaveOne Gold Primary (WOG) reciprocating files at WL. Apically extruded debris during instrumentation was picked up into pre-weighed Eppendorf tubes. The weight of the dry extruded debris was calculated by subtracting the pre- and post-instrumentation weights of the tubes in each group. The total time elapsed during the canal preparation was calculated with a chronometer. The data were analyzed using one-way ANOVA and post hoc Tukey tests. Results. The WGG/WOG group extruded significantly fewer debris than the WOG and PG/WOG groups (P<0.05). There was no significant difference between the WOG and PG/WOG groups (P>0.05). The WGG/WOG and PG/WOG groups were significantly faster than the WOG group. Conclusion. The amount of debris extruded apically significantly diminished when conventional WGG was implemented before using WOG. The total preparation time significantly diminished when the WOG file was used in combination with reciprocating and rotary glide path preparation techniques.

A male elderly patient came with buccal mucosa swelling associated with tooth 46 and 47. Periapical radiograph confirmed the presence of periapical lesion and narrow root canals on both teeth. Challenging impediments were sensed upon negotiating most of the narrow root canals which were common in elderly patients. Glide path creation involved pre-flaring, K-file bending, watch winding movement, and very gentle strokes. After achieving patency, shaping, cleaning, and sealing phase can be performed.

Objective: To determine the frequency of root canal treatment in endodontic department of dental colleges of Karachi. StudyDesign: Cross-sectional study. Place and duration of study: Department of endodontics, Sir Syed Dental College & Hospital, Karachi from1st May 2011 to 31st August 2011. Material and Methods: Of the 400 teeth from 370 individuals (age range 12-50 years) were endodonticallytreated during four months by faculty members and postgraduate residents enrolled in a specialisation programme in department ofEndodontics. All patients were examined clinically and radiographically. For each case, information was collected in specifically designedproforma including location of the affected tooth, age and gender and reasons for endodontic treatment. Results: Of the 400 treated teeth, 225(56.25%) were mandibular and 175 (43.75%) were maxillary teeth. 236 teeth (59.0%) were from females and 164 (41.0%) from males.Significant differences were found between the maxillary and mandibular arch. Molars and premolars required significantly more frequentendodontic treatment than canines and incisors as revealed in fig.1. The most frequently treated tooth was the mandibular right first molar(9.12%) followed by the mandibular left first molar (7.07%). The mandibular first molar was the most common tooth to undergo endodonticprocedure than maxillary first molar. The most frequently diagnosed pathosis was irreversible pulpitis (44%), pulp necrosis (22%), retreatmentendodontic (17%), elective RCTs (10%) traumatic exposures were (7%) as shown in fig. II. Conclusions: Irreversible pulpitis was the mostfrequent cause of root canal treatment followed by pulp necrosis. Teeth of females required more endodontic treatment than males. The mostfrequent root canals were carried out in mandibular molars than maxillary molars.

Abstract Background Radiographic analysis of tooth morphology is mandatory for accurate calibration of the degree of canal curvature angle and radiographic working length to its real dimensions in case difficulty assessment protocols. This study aimed to determine the impact of the degree of root canal curvature angle on maintaining the real working length and the original canal axis of prepared root canals using a reciprocating rotary instrumentation technique. Methods Radiographic image analysis was performed on 60 extracted single-rooted human premolar teeth with a moderate canal curvature (10°–25°) and severe canal curvature (26°–70°). Working length and longitudinal canal axis were determined using cone-beam computed tomography (CBCT) and digital periapical radiography. The real canal length was determined by subtracting 0.5 mm from the actual canal length. Root canals were prepared using the WaveOne Gold reciprocating file (Dentsply Maillefer, Ballaigues, Switzerland). Results There was no significant relation of the degree of canal curvature angle to the accuracy of radiographic working length estimated on CBCT and digital periapical radiographic techniques (P > 0.05). Postinstrumentation changes in the original canal axis between moderate and severe canal curvature angles, assessed on CBCT and periapical digital radiographic images were statistically non-significant (P > 0.05). Conclusions A standardized digital periapical radiographic method performed similarly to the CBCT technique near to its true working length. No significant interaction exists between the diagnostic working length estimation, postoperative root canal axis modification, and the degree of canal curvature angle, using reciprocating rotary instrumentation technique.
