Application of an interactive computer program to manage a problem-based dental curriculum.

Managing the change from traditional to problem-based learning (PBL) curricula is complex because PBL employs problem cases as the vehicle for learning. Each problem case covers a wide range of different learning issues across many disciplines and is coordinated by different facilitators drawn from the school's multidisciplinary pool. The objective of this project was to adapt an interactive computer program to manage a problem-based dental curriculum. Through application of a commercial database software--CATs (Curriculum Analysis Tools)--an electronic database for all modules of a five-year problem-based program was developed. This involved inputting basic information on each problem case relating to competencies covered, key words (learning objectives), participating faculty, independent study, and homework assignments, as well as inputting information on contact hours. General reports were generated to provide an overview of the curriculum. In addition, competency, key word, manpower, and clock-hour reports at three levels (individual PBL course component, yearly, and the entire curriculum) were produced. Implications and uses of such reports are discussed. The adaptation of electronic technology for managing dental curricula for use in a PBL curriculum has implications for all those involved in managing new-style PBL dental curricula and those who have concerns about managing the PBL process.

Patient-centred outcome measures in oral surgery: validity and sensitivity.

The performances of patient-centred outcome measures after oral surgery were evaluated in a prospective cohort study of 100 patients who had third molar extractions. Participants self-completed a questionnaire incorporating a general health (12-item short form health survey: SF-12) and two specific outcome scales to oral health (oral health impact profile: OHIP-14, and The United Kingdom Oral Health related Quality of Life measure: OHQoL-UK) preoperatively, daily during the immediate postoperative period, and at the review appointment (7-days later). Ninety-seven completed the study. History of 'taking time off' work/study because of pericoronitis during the past year was significantly associated with preoperative OHIP-14 and OHQoL-UK scores. There were significant differences in SF-12, OHIP-14, OHQoL-UK scores during the immediate postoperative period compared with preoperatively, when postoperative symptoms were prevalent. At the review appointment, OHIP-14 and OHQoL-UKscores were associated with clinical findings. The measures were valid and sensate in relation to oral surgery. However, those specific to oral health were more discerning than the general scale.

Can third molar surgery improve quality of life? A 6-month cohort study.

PURPOSE: In this study, we evaluated patients' perceptions of changes in oral health-related quality of life (OHQOL) over a 6-month period after third molar surgery. PATIENTS AND METHODS: One hundred patients participated in this prospective study. Two specific OHQOL measures, the 14-item Oral Health Impact Profile (OHIP-14) and the 16-item UK Oral Health-Related Quality of Life measure (QHQoL-UK), were administered to the study group before surgery. Standardized surgical and analgesic protocols were used. Patients kept a diary of changes in life quality each postoperative day (POD) for 7 days and were contacted at 1, 3, and 6 months after surgery. RESULTS: Both measures identified a significant deterioration in quality of life in the immediate postoperative period (P <.01). However, there was an improvement in OHQOL compared with preoperative status at 1 (P <.05), 3 (P <.05), and 6 (P <.01) months after surgery. Patients perceived physical, social, and psychologic changes in life quality after surgery. Previous pericoronitis was associated with changes in quality of life (P <.05). CONCLUSION: The study concludes that third molar surgery is associated with changes in OHQOL. This has implications for understanding the value of third molar surgery from patients' perspectives and in assessing health gain.

The use of lipiodol in spiral tomography for dental implant imaging.

Preoperative radiographic assessment is mandatory for the meticulous treatment planning and successful placement of implants. The precise topographical evaluation of selected implant sites, apart from the most straightforward cases, requires tomographic examination with the use of diagnostic radiographic templates. The incorporation of various radiopaque materials such as barium sulphate and lead foil as radiographic markers had not been entirely satisfactory. A new contrast medium, Lipiodol ethiodized oil (Laboratoire Guerbet, Paris, France), can easily be mixed with the monomer of autopolymerizing acrylic resin. The resultant acrylic template has several advantages. The tomographic images (Scanora; Soredex Orion Corporation, Helsinki, Finland) are radiographically homogenous and show the contour of the future prosthesis, the angulation of the planned implant, and the thickness of the soft tissue. In addition, the radiopaque template is optically transparent (with a slight yellow tint), which facilitates good visibility of surgical sites when the template is modified to become the surgical guide for implant placement. This transparent template can be further modified for implant position registration at the time of surgery. Because this multipurpose template is simple to construct and inexpensive, it can be recommended for routine use in implant dentistry.

Precision surgical template for implant placement: a new systematic approach.

The importance of a precise surgical template for implant placement cannot be overstated. The radiographic template carries both clinical and radiographic information for the planning of fixture angulation and location. This article describes a systematic approach to the fabrication of a dual-purpose radiographic surgical template. The simple steps result in the accurate transfer of radiographic information to the surgical template with no need for complex equipment or maneuvers. key words: dental implants, implant placement, radiographic template, surgical template
