Radiographic Interpretation (radiographic + interpretation)
Selected AbstractsApexogenesis after initial root canal treatment of an immature maxillary incisor , a case reportINTERNATIONAL ENDODONTIC JOURNAL, Issue 1 2010S. R. Kvinnsland Abstract Aim, To present a case where a traumatized, immature tooth still showed capacity for continued root development and apexogenesis after root canal treatment was initiated based on an inaccurate pulpal diagnosis. Summary, Traumatic dental injuries may result in endodontic complications. Treatment strategies for traumatized, immature teeth should aim at preserving pulp vitality to ensure further root development and tooth maturation. A 9-year-old boy, who had suffered a concussion injury to the maxillary anterior teeth, was referred after endodontic treatment was initiated in tooth 21 one week earlier. The tooth had incomplete root length, thin dentinal walls and a wide open apex. The pulp chamber had been accessed, and the pulp canal instrumented to size 100. According to the referral, bleeding from the root made it difficult to fill the root canal with calcium hydroxide. No radiographic signs of apical breakdown were recorded. Based on radiographic and clinical findings, a conservative treatment approach was followed to allow continued root development. Follow-up with radiographic examination every 3rd month was performed for 15 months. Continued root formation with apical closure was recorded. In the cervical area, a hard tissue barrier developed, which was sealed with white mineral trioxide aggregate (MTA). Bonded composite was used to seal the access cavity. At the final 2 years follow-up, the tooth showed further root development and was free from symptoms. Key learning points, ,,Endodontic treatment of immature teeth may result in a poor long-term prognosis. ,,The pulp of immature teeth has a significant repair potential as long as infection is prevented. ,,Treatment strategies of traumatized, immature permanent teeth should aim at preserving pulp vitality to secure further root development and tooth maturation. ,,Radiographic interpretation of the periapical area of immature teeth may be confused by the un-mineralized radiolucent zone surrounding the dental papilla. [source] Anomalous mandibular premolars: a mandibular first premolar with three roots and a mandibular second premolar with a C-shaped canal systemINTERNATIONAL ENDODONTIC JOURNAL, Issue 11 2008B. M. Cleghorn Abstract Aim, To describe unusual variations in the root morphology and root canal systems of mandibular first and second premolar teeth extracted for orthodontic reasons. Summary, Normally mandibular first and second premolar teeth have single roots with single canals. A 15-year-old patient presented for orthodontic treatment and two mandibular premolar teeth were examined post-extraction. The mandibular first premolar exhibited three distinct, separate roots and the mandibular second premolar exhibited a C-shaped root canal system. The coronal morphology of each of the mandibular premolars revealed dimensions and anatomy within normal limits. The incidence of a three-rooted mandibular first premolar is approximately 0.2%. Key learning points ,,Thorough clinical and radiographic interpretation is important in recognizing anomalous root and root canal systems. ,,The most common forms of root and canal systems and its aberrations must be understood to realize variations from normal do occur. ,,Successful root canal treatment requires an accurate diagnosis of the root canal system using all available aids. ,,Value of microcomputed tomography in the study of anatomy ex vivo and cone-beam tomography in clinical endodontics of complex premolar cases is increasing.

[source] Receiving: The Use of Web 2.0 to Create a Dynamic Learning Forum to Enrich Resident EducationACADEMIC EMERGENCY MEDICINE, Issue 2009Adam Rosh Receiving (http://www.drhem.com) is a powerful web-based tool that encompasses web 2.0 technologies. "Web 2.0" is a term used to describe a group of loosely related network technologies that share a user-focused approach to design and functionality. It has a strong bias towards user content creation, syndication, and collaboration (McGee 2008). The use of Web 2.0 technology is rapidly being integrated into undergraduate and graduate education, which dramatically influences the ways learners approach and use information (Sandars 2007). Knowledge transfer has become a two-way process. Users no longer simply consume and download information from the web; they create and interact with it. We created this blog to facilitate resident education, communication, and productivity. Using simple, freely available blog software (Wordpress.com), this inter-disciplinary web-based forum integrates faculty-created, case-based learning modules with critical essays and articles related to the practice of emergency medicine (EM). Didactic topics are based on the EM model and include multi-media case presentations. The educational modules include a visual diagnosis section (VizD), United States Medical Licensing Examination (USMLE) board-style cases (quizzER), radiographic interpretation (radER), electrocardiogram interpretation (Tracings), and ultrasound image and video clip interpretation (Morrison's Pouch). After viewing each case, residents can submit their answers to the questions asked in each scenario. At the end of each week, a faculty member posts the answer and facilitates an online discussion of the case. A "Top 10 Leader Board" is updated weekly to reflect resident participation and display a running tally of correct answers submitted by the residents. Feedback by the residents has been very positive. In addition to the weekly interactive cases, Receiving also includes critical essays and articles on an array of topics related to EM. For example, "Law and Medicine" is a monthly essay written by an emergency physician who is also a lawyer. This module explores legal issues related to EM. "The Meeting Room" presents interviews with leading scholars in the field. "Got Public Health?", written by a resident, addresses relevant social, cultural, and political issues commonly encountered in the emergency department. "Mini Me" is dedicated to pediatric pearls and is overseen by a pediatric emergency physician. "Sherwin's Critical Care" focuses on critical care principles relevant to EM and is overseen by a faculty member. As in the didactic portion of the website, residents and faculty members are encouraged to comment on these essays and articles, offering their own expertise and interpretation on the various topics. Receiving is updated weekly. Every post has its own URL and tags allowing for quick and easy searchability and archiving. Users can search for various topics by using a built-in search feature. Receiving is linked to an RSS (Really Simple Syndication) feed, allowing users to get the latest information without having to continually check the website for updates. Residents have access to the website anytime and anywhere that the internet is available (e.g., home computer, hospital computer, IphoneÔ, BlackBerryÔ), bringing the classroom to them. This unique blend of topics and the ability to create a virtual interactive community creates a dynamic learning environment and directly enhances resident education. Receiving serves as a core educational tool for our residency, presenting interesting and relevant EM information in a collaborative and instructional environment. [source] | ||||||||||
