Internet usage for dentistry and medicine is growing. Using search engines available on the Internet, websites for oral pathology and oral medicine information resources are explored and evaluated. A framework, whereby the personal digital assistant is used in conjunction with the Internet to enhance the practice and education of oral pathology, is proposed. (+info)
Oral pathology in the dental curriculum: a guide on what to teach.
There has been considerable disagreement among educators on the topics and details of topics that should be included in the teaching of oral pathology to dental students and graduate students in dental specialties. Various authorities have recommended core curricula that range from comprehensive teaching of eighteen categories, each with up to nine subheadings, covering hundreds of entities, to as few as approximately fifty of the most common lesions that affect the oral and maxillofacial region. This article offers a curriculum planning model designed to help faculty make decisions about course content and emphases. The model allows instructors to assess content relevance and priority based on three criteria: 1) commonness, 2) uniqueness, and 3) significance of diseases and conditions. The product of this decision-making process is a relevance score that can serve as a guideline for the choice and details of topics to be included in oral pathology courses. (+info)
Correcting for guessing increases validity in multiple-choice examinations in an oral and maxillofacial pathology course.
A standard correction for random guessing on multiple-choice examinations was examined retrospectively in an oral and maxillofacial pathology course for second-year dental students. The correction was a weighting formula for points awarded for correct answers, incorrect answers, and unanswered questions such that the expected value of the increase in test score due to guessing was zero. We compared uncorrected and corrected scores on examinations using a multiple-choice format with scores on examinations composed of short-answer questions. The short-answer format eliminated or at least greatly reduced the potential for guessing the correct answer. Agreement of corrected multiple-choice scores with short-answer scores (intraclass correlation coefficient 0.78) was significantly (p=0.015) higher than agreement of uncorrected multiple-choice scores with short-answer scores (intraclass correlation coefficient 0.71). The higher agreement indicated increased validity for the corrected multiple-choice examination. (+info)
Comparison of accuracy captured by different controlled languages in oral pathology diagnoses.
This project was comparing the accuracy of capturing the oral pathology diagnoses among different coding systems. 55 diagnoses were selected for comparison among 5 coding systems. The results of accuracy in capturing oral diagnoses are: AFIP (96.4%), followed by Read 99 (85.5%), SNOMED 98 (74.5%), ICD-9 (43.6%), and CDT-3 (14.5%). It shows that the currently used coding systems, ICD-9 and CDT-3, were inadequate, whereas the AFIP coding system captured the majority of oral diagnoses. In conclusion, the most commonly used medical and dental coding systems lack terms for the diagnosis of oral and dental conditions. (+info)
Computerized oral brush biopsy became commercially available in 1999. The objectives of this study were to provide senior dental students with the clinical competency to perform oral brush biopsy and to evaluate the extent to which students used this technique and the outcomes of their biopsy techniques. During the 2004-05 academic year, 114 senior dental students at The Ohio State University College of Dentistry participated in a brush biopsy instructional program. Brush biopsy training was part of their outreach and engagement experience. Technique instruction included 1) completion of thirteen interactive online educational modules, 2) discussion of a written protocol including clinical photographs and an oral pathology position paper, and 3) performance of a trial demonstration brush biopsy on each other. Eighty-one students submitted brush biopsies on clinical patients. Lesions were found in approximately one out of every twenty patients. Seventy-four biopsy results (91 percent) were diagnostic although seventeen (21 percent) were limited by suboptimal cellular representation and seven (9 percent) were inadequate. The high percentage (71 percent) of students who actually applied their training in a true clinical setting indicates that the program was successful in providing dental students the information necessary to perform this procedure on their own. However, the number of incomplete specimens suggests the need for technique refinement and additional clinical experience. (+info)
University of Florida College of Dentistry's "Case of the Month": Evaluating a web-based continuing dental education course for clinical oral pathology.
Over the last decade, online continuing dental education (CDE) has seen a major transformation in the way it is delivered, marketed, and accessed. The University of Florida College of Dentistry (UFCD) developed and evaluated a web-based CDE format ("Case of the Month") that specifically focused on clinical oral pathology. Over a four-month period, three oral pathology cases were presented monthly (a total of twelve cases overall) using a clinical pathologic conference format including a brief patient history, along with pictures and radiographs needed to make a treatment diagnosis. A differential diagnosis in the form of a question was developed, followed by a detailed description and rationale describing why the option was correct or incorrect. At the conclusion of the case of the month, respondents completed an online survey that ascertained their needs, expectations, attitudes, level of clinical knowledge gained, and experience with the online environment. The primary purpose of this study was to evaluate the expectations and attitudes of these CDE participants. Results suggested that the participants' needs and expectations were generally met: they were able to navigate the website with ease and found the design to be appealing. The biggest disadvantage reported was the inability to communicate with others, including the instructor, while viewing the case, and more respondents would like to have seen some more general/common oral pathology information.

University of Toronto's dental school shows "new teeth": moving towards online instruction.
This article presents the approach the Faculty of Dentistry at the University of Toronto employed to modernize its methods of instruction by using online technologies. A small team of faculty, students, and content developers was assembled to work with individual faculty members to brainstorm and research ideas for innovative teaching practices in dental studies. The team was not content to simply post digital versions of the ubiquitous PowerPoint lectures in Blackboard, selected in 2006 by the University of Toronto as its sole platform for online course delivery, but rather set out to introduce interactivity with the course material. Consequently, a series of interactive applications was created, such as the virtual microscope in Oral Pathology, the 3D cavity preparations in Restorative Dentistry, and the Master Media Repository. During the summer of 2006, the Faculty of Dentistry made progress toward becoming one of the university's front-runners in online course innovation. The result of this collaboration between faculty members and the team was ten courses with interactive online presence, representing approximately 20 percent of the undergraduate curriculum. Since the summer of 2006, the Faculty of Dentistry has continued to pursue its goal of providing meaningful online instruction in all of its courses. (+info)
Prospective implementation of correction for guessing in oral and maxillofacial pathology multiple-choice examinations: did student performance improve?
A standard correction for random guessing on multiple-choice examinations was implemented prospectively in an Oral and Maxillofacial Pathology course for second-year dental students. The correction was a weighted scoring formula for points awarded for correct answers, incorrect answers, and unanswered questions such that the expected gain in the multiple-choice examination score due to random guessing was zero. An equally weighted combination of four examinations using equal numbers of short-answer questions and multiple-choice questions was used for student evaluation. Scores on both types of examinations, after implementation of the correction for guessing on the multiple-choice component (academic year 2005-06), were compared with the previous year (academic year 2004-05) when correction for guessing was not used for student evaluation but was investigated retrospectively. Academically, the two classes were comparable as indicated by the grade distributions in a General Pathology course taken immediately prior to the Oral and Maxillofacial Pathology course. Agreement between scores on short-answer examinations and multiple-choice examinations was improved in the 2005-06 class compared with the 2004-05 class. Importantly, the test score means were higher on both the short-answer and multiple-choice examinations in the Oral and Maxillofacial Pathology course, and the standard deviations were significantly smaller in 2005-06 compared to 2004-05; these differences reflected an upward shift in the lower part of the grade distributions to higher grades in 2005-06. Furthermore, when students were classified by their grade in the General Pathology course, students receiving a C (numerical grade of 70-79 percent) in General Pathology had significantly improved performance in the Oral and Maxillofacial Pathology course in 2005-06, relative to 2004-05, on both short-answer and multiple-choice examinations representing an aptitude-treatment interaction. We interpret this improved performance as a response to a higher expectation imposed on the 2005-06 students by the prospective implementation of correction for guessing. (+info)
