The findings of this study suggest that the preemptive and postoperative use of celecoxib or dexamethasone were effective in the management of postoperative pain following open-flap debridement.

The adoption of a preemptive medication protocol using etoricoxib or dexamethasone may be considered effective for pain and discomfort prevention after open-flap debridement surgeries.

Introduction Education in the health sciences has been undergoing profound changes due to the incorporation of information and communication technologies. Students learn through a variety of approaches, according to their learning styles. Blended learning, which combines technology-aided learning (e-learning) with traditional face-to-face teaching methods, has been found to improve learning outcomes. Objective The aims of the present study were to evaluate the learning styles of undergraduate dental students and their experience towards the use of e-learning. Material and method Two electronic questionnaires were sent to 174 students. The learning styles were determined by the Felder & Soloman Index (ILS), which evaluates the following four dimensions of learning: processing information (active-reflexive); perceiving information (sensorial-intuitive); receiving information (visual-verbal); and understanding information (sequential-global). To determine the e-learning experience we used four questions (Likert scale – five-point) which addressed the experience and the use of information and communication technologies. Result Most students presented a well-balanced style for the active-reflective (60%) and sequential-global (68%) domains. The sensing style (64%) was predominant. A lower percentage presented a global characteristic (9%). We did not find significant differences regarding the age groups (19-21 and 22-33 years) and genders (P>0.05, χ 2). However, in terms of age the difference was significant concerning websites helping in learning (P=0.0363, Mann-Whitney). Conclusion We conclude that the students do not have the same learning styles and e-learning experience. Methods such as blended learning could provide advantages when teaching undergraduate dental students.

It was concluded that a single etoricoxib dose is not superior to two split doses of celecoxib when used for pain prevention after open-flap debridement surgery.

The aim of this study was to evaluate the subcutaneous biocompatibility of: Epiphany, AH Plus, Pulp Canal Sealer and Sealapex root canal sealers. Sixty rats were randomly assigned to 4 groups, according to the sealer. Polyethylene tubes containing the tested materials were inserted into the connective tissue. The implants were removed after 7, 15 and 30 days, and the tissue samples were processed, stained and examined by light microscopy. The descriptive analysis considered: thickness of the fibrous capsule, severity of the inflammatory reaction, and presence of giant cells. After 7 days, all sealers induced moderate to severe inflammatory reaction. After 15 days, Epiphany and AH Plus sealers showed a moderate inflammatory reaction, while Pulp Canal Sealer and Sealapex induced severe and mild inflammatory reactions, respectively. After 30 days, mild inflammatory reactions were observed for Epiphany, Sealapex and AH Plus. Sealapex induced the lowest inflammatory response at all evaluation periods, and only Pulp Canal Sealer did not show a decreased in the inflammatory reaction over time.
