PRIDASE 2024 guidelines for reporting diagnostic accuracy studies in endodontics: A consensus-based development.

Studies investigating the accuracy of diagnostic tests should provide data on how effectively they identify or exclude disease in order to inform clinicians responsible for managing patients. This consensus-based project was undertaken to develop reporting guidelines for authors submitting manuscripts, which describe studies that have evaluated the accuracy of diagnostic tests in endodontics. These guidelines are known as the Preferred Reporting Items for Diagnostic Accuracy Studies in Endodontics (PRIDASE) 2024 guidelines. A nine-member steering committee created an initial checklist by integrating and modifying items from the Standards for Reporting of Diagnostic Accuracy (STARD) 2015 checklist and the Clinical and Laboratory Images in Publications (CLIP) principles, as well as adding a number of new items specific to the specialty of endodontics. Thereafter, the steering committee formed the PRIDASE Delphi Group (PDG) and the PRIDASE Online Meeting Group (POMG) in order to collect expert feedback on the preliminary draft checklist. Members of the Delphi group engaged in an online Delphi process to reach consensus on the clarity and suitability of the items in the checklist. The online meeting group then held an in-depth discussion on the online Delphi-generated items via the Zoom platform on 20 October 2023. According to the feedback obtained, the steering committee revised the PRIDASE checklist, which was then piloted by several authors when preparing manuscripts describing diagnostic accuracy studies in endodontics. Feedback from this process resulted in the final version of the PRIDASE 2024 checklist, which has 11 sections and 66 items. Authors are encouraged to use the PRIDASE 2024 guidelines when developing manuscripts on diagnostic accuracy in endodontics in order to improve the quality of reporting in this area. Editors of relevant journals will be invited to include these guidelines in their instructions to authors.

Implementation of Digital Radiography during Root Canal Treatments in Saudi Endodontic and General Dental Practice.

Objective: To report usage of full-digital-radiography (FDR) during root-canal-treatments (RCTs) in Saudi dental-practice and to explore factors and measures that obstacle/contribute to better implementation. Methods: Following a pilot study, questions on demography, types of radiographic systems used during RCTs, advantages and disadvantages of FDR, reasons of not using it and measures that increase its implementation were included. The sample size was calculated considering the total number of general dentists (GDs) in Saudi Arabia and a 50-60% expected response rate. The questionnaire was emailed to 550 GDs and all endodontists in Saudi Arabia (185). A solo a reminder was emailed two months later. Data were analyzed by the Chi-square test at P=0.05. Results: Most participants (64.9%) used FDR for RCTs (P<0.001); with all endodontists (100%) and 52% of GDs (P<0.001). While all who were working in governmental-academia (100%) used FDR, 69.2% in private-academia did so (P<0.001); with no difference between private and governmental-clinics (60.6 and 69.2%). As the weekly-performed RCTs increased and participants' experience decreased, FDR usage increased (P<0.05). While high-cost was the main FDR disadvantage, faster-workflow, better image-quality and less-radiation were the main advantages (P<0.001). The majority (76.1%) of FDR none-users were doing so because of unavailability. Participants reported lower-cost and better undergraduate-education as most effective measures that increase FDR implementation in dental-practice. Conclusion: FDR was adopted to good extent in Saudi dental-practice. Financial aspects were the main concern that should be addressed to increase FDR implementation in private practice. Endodontists showed better perception towards FDR and suggested more attention to educational aspects.

Recomendaciones de la Asociación Española de Endodoncia sobre el uso de antibióticos en endodoncia / No disponible

Las encuestas realizadas en España ponen de manifiesto que los dentistas prescriben con frecuencia antibióticos en casos donde no están indicados, tanto a nivel terapéutico (pulpitis irreversible sintomática, pulpa necrótica con absceso apical agudo, periodontitis apical asintomática, absceso apical localizado sin síntomas generales en pacientes sanos), como profilácticamente. Esto puede contribuir al desarrollo de cepas bacterianas resistentes. La Asociación Española de Endodoncia (AEDE) propone estas recomendaciones, fruto del consenso de un comité de expertos y basadas en la evidencia científica, para proporcionar a los dentistas, y a otros trabajadores de la salud, criterios científicos sobre el uso de antibióticos en el tratamiento de las infecciones endodónticas, en la profilaxis antibiótica en endodoncia, y sobre el uso de antibióticos tópicos en endodoncia. Cuando la inflamación es localizada y discreta y no existe compromiso sistémico, el objetivo principal del tratamiento endodóntico es lograr el drenaje, no siendo necesarios los antibióticos. El tratamiento antibiótico sólo está indicado en los siguientes casos: 1) Pacientes inmunodeprimidos; 2) Absceso apical agudo con sintomatología sistémica (fiebre, adenopatías...); 3) Absceso api-cal agudo que progresa y se expande, como es el caso de las celulitis cérvico-faciales; 4) Reimplante de dientes avulsionados. El antibiótico de elección es la amoxicilina, con / sin ácido clavulánico, y la clindamicina en pacientes alérgicos a las penicilinas. La mejoría clínica debe ser la guía para la duración del tratamiento (3-5 días), y cuando exista evidencia de que los signos y síntomas han remitido, el tratamiento antibiótico debe interrumpirse. Respecto a la profilaxis antibiótica en endodoncia, debe considerarse en los siguientes casos: 1) Pacientes inmunodeprimidos; 2) Pacientes con riesgo de desarrollar endocarditis bacteriana; 3) Pacientes portadores de prótesis articulares; 4) Pacientes oncológicos sometidos a radioterapia; 5) Pacientes en tratamiento con bisfosfonatos por vía intravenosa. En estos casos la pauta será amoxicilina por vía oral, 2 gr en adultos o 50 mg / kg en niños, administrada 1 hora antes de la intervención

[Consensus recommendations from Chinese experts on the standard operation procedure of dental operative microscope in endodontics and operative dentistry].

Dental operative microscope has been wildly used in endodontics and operative dentistry for many years. Many progresses have been made by using operative microscope in improving the outcomes of root canal therapy, endodontic surgery and operative dentistry. However, in clinical practice, improper use of the dental operative microscope is not uncommon, the reason related to which is the operator's lack of understanding and mastering not only the properties but also the standard operative procedure of the dental operative microscope. To this end, in October 2019, the vice chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, professor Liang Jingping, organized a group of professional experts in this field, convened a meeting about the standard operative procedure of dental operative microscope. Experts at the meeting had a very heated discussion and the consensuses were reached.

Determinación de la Longitud de Trabajo Mediante Localizador Electrónico de Foramen Apical y CBCT a Través del Software 3D Endo de Dentsply Sirona: Estudio Comparativo in vitro / Determination of Working Length Using Electronic Locator for Apex and CBCT with 3D Endo Dentsply Sirona Software: Comparative in vitro Study

RESUMEN: En la historia de la Endodoncia, se han utilizado distintos métodos para determinar la longitud de los canales radiculares, como sensación táctil y radiografías. Últimamente, han adquirido gran importancia los localizadores apicales electrónicos, por su gran precisión. Actualmente se ha incorporado el uso de imagenología con Cone Beam. Debido a que existen muchas formas de medir dicha longitud, es necesario ponerlos a prueba y ver si se asemejan a la técnica gold estándar definida en la literatura como el localizador electrónico de foramen apical. El propósito de esta investigación es determinar si existen diferencias estadísticamente significativas en la medida de la longitud de trabajo entre el localizador electrónico de foramen apical, y el uso de Cone Beam procesado con el software 3D endo de Dentsply Sirona. Para esto, se seleccionaron 30 premolares extraídos; se les tomó un Cone Beam para ser analizados con el software 3D endo y medir la longitud de trabajo. Una vez hecho esto, se realizó manualmente cavidad de acceso y se preparó el tercio cervical con fresas Gates Glidden 1 y 2; luego, los dientes fueron colocados en un modelo Pro Train, que asemejó las propiedades de los dientes en la cavidad oral, para permitir el uso del localizador electrónico de foramen y determinar la longitud de trabajo. Una vez obtenidos los datos, fueron comparados a través del Test de Proporciones (p=0.05 hipotético), dando como resultado p=0,2 lo que indica que no existen diferencias estadísticamente significativas en la medida de la longitud de trabajo entre ambos métodos.

ABSTRACT: Various methods have been used in the history of endodontics, to determine the length of the root canals (working length), such as tactile sensation and X-rays. Recently, apical locators have acquired importance, due to their precision. The use of Cone Beam has now also been incorporated. Because there are many ways to measure this length, it is necessary to test them and see if they resemble the standard gold measurement technique defined in the literature as the electronic apex locators. The purpose of this research is to determine whether there are statistically significant differences in the working length between the electronic apex locators, and the use of Cone Beam processed with the Software 3D Endo by Dentsply Sirona. For this, 30 extracted pre-molars were selected, for Cone Beam tomography and 3D endo Software analysis, to measure the working length. Once this was carried out, cavity preparation was performed manually, and the cervical third approached with gates glidden drills 1 and 2. Subsequently, the teeth were placed in a Pro Train model, which resembled the properties of the teeth in the oral cavity, to allow the use of the electronic apex locators to determine the working length.Once the data were obtained, they were compared through the proportions Test (p = 0.05 hypothetical), resulting in p = 0.2, indicating that there are no statistically significant differences in the working length between the two methods.

Clinical applications, accuracy and limitations of guided endodontics: a systematic review.

BACKGROUND: The novel concept of guided endodontics has been reported as an effective method to obtain safe and reliable results in root canal treatment. AIM: To evaluate by means of a systematic review the clinical applications, accuracy and limitations of guided endodontic treatment. DATA SOURCES: A search of the literature was performed on PubMed, Embase, Web of Science and Cochrane Library databases, until 25 April 2019. No language or year restrictions were applied. STUDY ELIGIBILITY CRITERIA: Articles that answered the research question, including case reports, in vitro and ex vivo studies were included. Data extraction was performed independently by two reviewers. STUDY APPRAISAL: Quality assessment was done using STROBE, CARE and Modified CONSORT guidelines for observational, case reports and pre-clinical studies, respectively. RESULTS: A total of 22 articles, including fifteen case reports, six pre-clinical studies (in vitro and ex vivo studies) and one observational study, were included. LIMITATIONS AND CONCLUSIONS: Even though the level of evidence is low, and the methodology described among studies heterogeneous, all articles describe guided access cavity preparation and guided surgery as being highly accurate and successful techniques when comparing the drilled path to the planned treatment. More studies with a larger number of patients are necessary to obtain significant conclusions.

Assessing a training programme for primary care dental practitioners in endodontics of moderate complexity: Pilot data on skills enhancement and treatment outcomes.

Aims: To explore the impact of dedicated training to extend the skills of primary care practitioners on the quality of endodontic care, using clinical, radiographic and patient-related outcomes. Methods: The quality of endodontic treatment performed at the beginning and end of training to become dentists with extended skills (DES) in endodontics was assessed in vitro and in vivo from endo-training blocks and self-reported logbooks containing clinical notes and radiographs respectively. The quality of endodontic care delivered by DES post-training was measured using clinical and radiographic outcomes. Patient-related outcomes were assessed using a self-report questionnaire, including the Oral Health Impact Profile ­ Endodontic Outcome Measure (OHIP-EOM). Results: Data on eight dentists were examined pre-and post-training, five of whom participated in further follow-up investigations on the quality of endodontic care delivered to their patients. Significant improvements in skills were seen for all domains in vitro (p <0.05), and for all domains of the clinical treatment process, and achieving the correct working length of the root filling as seen by radiography in vivo (p <0.05). The quality of the clinical process was maintained following training. Positive patient outcome (OHIP-EOM) scores were recorded (mean score of 34.72, SD = 10.74, n = 120 pre-treatment and 25.85, SD = 7.74, n = 47 representing reduced impact at follow-up). The majority of patients reported being satisfied, or very satisfied, with the service they received (72.5%, n = 98); would use the service again (68.1%, n = 92); and would recommend the service to friends and family (74.8%, n = 101). Conclusions: Findings suggest that training for dentists working in practice can be successful in enhancing skills and changing practice, with evidence of high patient satisfaction and good clinical and patient-related outcomes. Pilot results must be interpreted with caution and further research is required.

European Society of Endodontology position statement: External Cervical Resorption.

This Position Statement represents the consensus of an expert committee convened by the European Society of Endodontology (ESE) on External Cervical Resorption (ECR). The statement is based on current clinical and scientific evidence as well as the expertise of the committee. The primary aim is to provide a current authoritative position on the aetiology, histopathology, clinical presentation and management of ECR, and also to highlight areas where there is minimal evidence. Previously published review articles provide more detailed background information and the basis for this position statement (International Endodontic Journal 51, 1205, 2018, International Endodontic Journal 51, 1224, 2018). It is intended that this position statement will be updated at appropriate intervals, as further evidence emerges.

Surgical experience, workload and learning curve vs postoperative outcome.

AIM: In this review, we look at the factor of the surgical experience and surgical workload in a variety of surgical disciplines and its effect on the intraoperative and postoperative complications rate. MATERIALS AND METHODS: An extensive systematic electronic search was carried out on the relevant databases. Two independent reviewers were engaged in selecting appropriate articles in line with the protocol. RESULTS: It was very interesting to see that only 52 studies could be identified as per the inclusion criteria and search keywords. This included studies from 1990 onwards, spanning all surgical disciplines. Six studies were identified in third molar surgery, one of the most common surgeries practiced across all surgical disciplines. Seven appropriate oral implant surgery studies were identified, covering two-stage implants and immediately loaded implants. The evidence was overwhelming that the surgeon's experience positively correlates with the level of osseointegration and implant success. An interesting study from general surgery highlighted the fact it is not unusual to see senior surgeons selected to operate on complex patients or carry out complex surgical procedures than their junior colleagues. In face, this may explain why a number of studies identified no difference in the surgical complications between seniors and juniors. CONCLUSIONS: Despite the fact that experience matters, many factors can influence the outcome of the surgery. If the surgeon, despite his/her lack of seniority, manages to utilise experience appropriately then there will be a beneficial outcome for the patient.
