Oral lesions in elderly population: a biopsy survey using 2250 histopathological records.

OBJECTIVE: To perform an oral biopsy survey focused on the incidence of oral lesions in Brazilian elderly patients. METHODS: A total of 17 329 oral biopsy records were analysed and divided into two age groups: elderly patients, > or =60 years old; and non-elderly patients, <60 years old. Information about sex, race, age and histopathological diagnosis (categorised in non-neoplastic and neoplastic lesions) was collected. Differences of diagnosis incidence were tested by comparison between two proportions (binomial test). RESULTS: The incidence of epithelial malignant neoplasms and pre-malignant lesions in the elderly group was higher than non-elderly group, as well as autoimmune diseases and salivary gland tumours. The three most prevalent lesions in the elderly group were inflammatory fibrous hyperplasia, squamous cell carcinoma, and fibroma. CONCLUSION: The distribution of oral diseases using biopsies allows greater accuracy in data about oral health of elderly patients, especially when considering malignant and pre-malignant lesions.

Teaching oral surgery to undergraduate students: a pilot study using a Web-based practical course.

The Internet has been used in oral surgery teaching mainly to deliver learning material across the World Wide Web and to make use of online interactivity resources in everyday surgical practice, such as by e-mails, discussion groups, and chats. The aim of this paper is to describe and evaluate a Web-based practical course on oral surgery principles, which was applied to undergraduate students. This course was investigated as a distance learning simulation in which the student would be performing surgical activities at home, and the teacher and the school environment would be absent. A Web site was created containing the course material. For this study, the students participated in the Web-based course in a multimedia lab equipped with computers and Internet, internal sound system and TV circuits. In the event of significant mistakes by students, the TV circuit could be used to show the correct procedure for all the participants at the same time. Microcameras were used to monitor the student's actions during the Internet use. Students' impressions were determined by a questionnaire. Computer manipulation with ease and antiergonomic postures were observed. We concluded that distance learning courses with practical modules must be considered as a special type of educational modality, with reference to the relationship between the student and the computer.
