    (2020-08-31) Oñate-Núñez, Héctor; Bravo, Alejandra; Arancibia, Carolina; Bustos, Paola; Karen, Cabrera
    Objective: This research aims to analyze the available spe-cialized literature concerning the association between Herpesviruses [Cytomegalovirus (CMV), Epstein Barr virus (EBV), Herpes Simplex virus (HSV)] and chronic periodontitis to clarify the possible role of these microorganisms in the progression and severity of the disease. Materials and Methods: A search for scientific articles was carried out in March 2019 in the main metasearch engines: PubMed /MEDLINE, SciELO, EBSCO, and the Trip search engine, to select articles according to the exclusion and inclusion criteria. The analysis of the articles was carried out through a data matrix expressed in frequency tables using descriptive statistics with measures of central tendency, dispersion, and correlation. Results: The results of this study show that the presence of CMV, EBV, and HSV in patients with chronic periodontitis is related to an increase in clinical parameters such as probing pocket depth (PD), clinical insertion loss (CIL) and bleeding on probing (BOP), in 96%, 60% and 40% of the studies, respectively, for HCMV; 96.55% (PD), 51.72% (CIL), and 48.28% (BOP) for EBV, and 80% (PD), 90% (CIL), and 60% (BOP) for HSV. The average prevalence of EBV, HCMV, and HSV was 46.3%, 35.4%, and 40.1%, respectively. Conclusions: EBV, CMV, and HSV could be associated with the progression and severity of periodontal disease as they are related to a greater probing depth, greater clinical insertion loss, and greater bleeding on probing. EBV presented a higher prevalence in the reviewed literature. More clinical studies are needed to verify a direct relationship between EBV, HSV, CMV, and periodontal disease, to confirm the trends observed in this work

    Experiences of professionalized Chilean dental educators. A qualitative study.
    (Journal of Oral Research, 2021) Oñate, Héctor; Segovia-Chamorro, Jaime; Cárcamo, Roberto; Bravo, Alejandra
    Introduction:The active learning process is certainly one of the most complex challenges in dental education. It is essential for the development of critical thinking and clinical skills. There is evidence of the need for teacher professionalization, but there is scarce literature reporting on the positive changes in the teaching profession based on such professionalization. The aim of the present study is to explore the experiences of the pedagogical performance of professionalized educators in dentistry. Material and Methods: A qualitative study was conducted using a design based on content analysis. The sample was selected for convenience and included dentists who have completed a master's degree in teaching in higher education, who were part of the teaching staff of a dental university program and with a career experience of at least 5 years. Semi-structured interviews were conducted, with three initial dimensions: Teaching Career, Motivation for Teacher Professionalization, and Impact on the teachinglearning process. The interviews were verbatim transcribed and content analysis was performed by the researchers using data triangulation. The research was approved by the research and ethics committee. Results: Six categories were established: Generational clash, Motivations to practice teaching, Motivations to professionalize teaching, Competences acquired after professionalization, Effects of professionalization in the classroom context, and Shortcomings of the professionalized educator. Conclusion: Professionalized dental educators show comprehensive improvements in their performance. They have developed practical competences for the specific needs of the courses they give.
