RESUMEN

An evidence-based (EB) approach has been a significant driver in reforming healthcare over the past two decades. This change has extended across a broad range of health professions, including oral healthcare. A key element in achieving an EB approach to oral healthcare is educating our practitioners, both current and future. This involves providing opportunities integrated within simulated and actual clinical settings for practitioners to learn and apply the principles and processes of evidence-based oral healthcare (EBOHC). Therefore, the focus of this discussion will be on ways in which EBOHC and associated research activities can be implemented into curricula, with the aim of improving patient care. This paper will initially define the scope of EBOHC and research, what these involve, why they are important, and issues that we need to manage when implementing EBOHC. This will be followed by a discussion of factors that enable successful implementation of EBOHC and research into curricula. The paper concludes with suggestions on the future of EBOHC and research in curricula. Key recommendations related to curricula include strengthening of the culture of a scientific approach to education and oral healthcare provision; complete integration of EBOHC into the curriculum at all levels; and faculty development to implement EBOHC based on their needs and evidence of effective approaches. Key recommendations to support implementation and maintenance of EBOHC include recognition and funding for high-quality systematic reviews and development of associated methodologies relevant for global environments; building global capacity of EBOHC researchers; research into improving translation of effective interventions into education and healthcare practice, including patient-reported outcomes, safety and harms, understanding and incorporation of patient values into EB decision-making, economic evaluation research specific to oral healthcare and effective methods for changing practitioner (faculty) behaviours; and extend access to synthesized research in 'user friendly' formats and languages tailored to meet users' needs. Realizing these recommendations may help to improve access to effective healthcare as a basic human right.

RESUMEN

The aim of this study was to evaluate the local changes in the crevicular gingival fluid (CGF) determined by the inflammatory and immune response in periodontitis and gingivitis. The selected patients presented gingivitis (n = 9) and periodontitis: aggressive periodontitis (n = 21) and adult periodontitis (n = 8). The crevicular fluid was provided from the gingival and periodontal pocket. The measurement of PMN-elastase in the CGF, using the ELISA method, showed a significant (p < 0.01) increase of the enzyme concentration in the aggressive periodontitis group (62.1 +/- 3.91 ng/ml) comparing to the gingivitis group (33.04 +/- 4.14 ng/ml) but also the increase (p < 0.05) of this enzyme in the adult periodontitis (43.6 +/- 2.16 ng/ml) comparing to the gingivitis, which indicated the evolutive aspects of the inflammatory reaction in these diseases. The increased production of PMN-E is the result of the activation of polymorphonuclear cells (PMN) as a reaction of the microbial attack. Degranulation and release of proteolytic enzymes including elastase, which present cytotoxic capacities, follow the activation of neutrophil granulocytes (PMN). The activated granulocytes release proinflammatory cytokines IL-1, TNF-alpha which augment the inflammatory immune response. The aggressive periodontitis group showed an increased CGF level of IL-1 (780.4 +/- 104 pg/ml) comparing to the gingivitis group (275.5 +/- 78 pg/ml) (p < 0.01). TNF-alpha also presented an increased level (p < 0.01) in the aggressive periodontitis group (16.3 +/- 2.3 pg/ml) comparing to the gingivitis group (4.1 +/- 1.2 pg/ml) as a consequence of the periodontium destruction and of the tissular necrosis in the former group. In conclusion, our study shows a significant increase of the PMN-elastase and proinflammatory cytokines level in CGF of patients with gingivitis and periodontitis. The intensity of the inflammatory response in these diseases is strongly correlated to the activation of the neutrophil granulocytes which release these biological active molecules that could be used as evolution markers of the disease.

RESUMEN

An improved knowledge of anatomy and psysiology of the apical radicular region has made mandatory a better classical endodontic technique concerning the apical limit of instrumentation, and has stressed the importance of a precise determination of the cemento-dentinal junction as the apical limit of canal obturation. On the basis of these orientations a clinical and radiographic study was carried out on 120 teeth extracted form humans, in which the frequency was determined of the excentric position of the cement conus with regard to the apex, and the distance between the cemento-dentinal junction and the apex. In 45 teeth in situ, with pulpar inflammation, gangrene and apical parodontitis a clinical and radiological appraisal was done of the cemento-dentinal junction, and evolution was followed after canal obturation.
