RESUMO

Radiologists should possess working knowledge of the embryological development and anatomy of the jaw and dentition in order to aid in the diagnosis of both simple and complex disorders that affect them. Here, we review the elaborate process of odontogenesis, as well as describe in detail the anatomy of a tooth and its surrounding structures.

RESUMO

Dental implants restore function to near normal in partially or completely edentulous patients. A root-form implant is the most frequently used type of dental implant today. The basis for dental implants is osseointegration, in which osteoblasts grow and directly integrate with the surface of titanium posts surgically embedded into the jaw. Radiologic assessment is critical in the preoperative evaluation of the dental implant patient, as the exact height, width, and contour of the alveolar ridge must be determined. Moreover, the precise locations of the maxillary sinuses and mandibular canals, as well as their relationships to the site of implant surgery must be ascertained. As such, radiologists must be familiar with implant design and surgical placement, as well as augmentation procedures utilized in those patients with insufficient bone in the maxilla and mandible to support dental implants.

RESUMO

Dental implants have increased in the last few decades thus increasing the number of complications. Since many of these complications are easily diagnosed on postsurgical images, it is important for radiologists to be familiar with them and to be able to recognize and diagnose them. Radiologists should also have a basic understanding of their treatment. In a pictorial fashion, this article will present the basic complications of dental implants which we have divided into three general categories: biomechanical overload, infection or inflammation, and other causes. Examples of implant fracture, loosening, infection, inflammation from subgingival cement, failure of bone and soft tissue preservation, injury to surround structures, and other complications will be discussed as well as their common imaging appearances and treatment. Lastly, we will review pertinent dental anatomy and important structures that are vital for radiologists to evaluate in postoperative oral cavity imaging.

RESUMO

The teeth are unique in that they provide a direct pathway for spread of infection into surrounding osseous and soft tissue structures. Periodontal disease is the most common cause of tooth loss worldwide, referring to infection of the supporting structures of the tooth, principally the gingiva, periodontal ligament, cementum, and alveolar bone. Periapical disease refers to an infectious or inflammatory process centered at the root apex of the tooth, usually occurring when deep caries infect the pulp chamber and root canals. We review the pathogenesis, clinical features, and radiographic findings (emphasis on computed tomography) in periodontal and periapical disease.

RESUMO

Starting in 2004, a medical school gross anatomy course faced with a 30% cut in hours went through an extensive redesign, which transformed a traditional dissection course into a course with a clinical focus, learning societies, and extensive on-line learning support. Built into the redesign process was an extensive and ongoing assessment process, which included student focus groups, faculty development, surveys, and examinations. These assessments were used formatively, to enhance the course from year to year, and summatively, to determine how well the course was meeting the new learning objectives. The assessments from focus groups and faculty development prompted changes in support structures provided to students and the training and preparation of faculty. Survey results showed that, after student satisfaction declined the first year, satisfaction increased steadily through the fourth iteration as the course gained acceptance by students and faculty alike. There was a corresponding increase in the performance of students on course examinations. An additional examination given to students one and a half and three years after their anatomy course ended demonstrated the redesigned course's long-term effectiveness for retaining anatomical knowledge and applying it to clinical cases. Compared to students who took the original course, students who took the shorter, more clinical course performed as well, or better, on each section of the examination. We attribute these positive results to the innovative course design and to the changes made based on our formative assessment program.

RESUMO

The exponential growth of medical knowledge presents a challenge for the medical school curriculum. Because anatomy is traditionally a long course, it is an attractive target to reduce course hours, yet designing courses that produce students with less understanding of human anatomy is not a viable option. Faced with the challenge of teaching more anatomy with less time, we set out to understand how students employ instructional media to learn anatomy inside and outside of the classroom. We developed a series of pilot programs to explore how students learn anatomy and, in particular, how they combine instructional technology with more traditional classroom and laboratory-based learning. We then integrated what we learned with principles of effective instruction to design a course that makes the most efficient use of students' in-class and out-of-class learning. Overall, we concluded that our new anatomy course needed to focus on transforming how medical students think, reason, and learn. We are currently testing the hypothesis that this novel approach will enhance the ability of students to recall and expand their base of anatomical knowledge throughout their medical school training and beyond.
