The identification of the associative relationships between ischemic stroke (IS) and risk factors such as advanced age and periodontitis is essential to design real screening protocols and to address them using primary and secondary preventive policies. This study primarily aimed to evaluate the diagnostic performance of the 2018 European Federation of Periodontology/American Academy of Periodontology (EFP/AAP) case definition in detecting periodontitis against the 2012 Centers for Disease Control and Prevention/American Academy of Periodontology (CDC/AAP) case definition in a group of IS patients. Secondarily, we report the periodontal status of IS patients and the associative relationship with respect to some risk factors. Patients with their first IS were assessed based on demographic data, medical, oral risk factors and periodontal parameters. The two case definitions were applied to identify the periodontitis burden. The agreement between the two case definition systems, as well as the misclassification ratio, were calculated. A total of 141 patients were included. According to the 2012 CDC/AAP and the 2018 EFP/AAP case definitions, a frequency of periodontitis of 98.5% and 97.8% based on two modalities of inclusion of cases in the severity groups, sensitivity values of 98.54% or 100%, and specificity values of 25% or 14.7% were calculated. Thus, the new case definition system has a higher capacity to detect periodontitis, especially the well-established forms.

The aims of this study were to identify the challenges in periodontology postgraduate residency programs during the COVID-19 pandemic by identifying the modifications of educational instruments, to evaluate the impact of hybrid education on periodontology postgraduate programs in terms of resident-centred outcomes, and to evaluate the education efficiency of an innovative teaching approach. Resident doctors from three Romanian dental faculties were included in study groups based on the intensity of clinical training. A web-based questionnaire was used to collect information on residents’ perception about teaching activity. Important educational changes were identified. Moreover, residents learned a periodontal procedure through online training and then performed it on preclinical models three times. The working times were recorded. Statistical analysis was performed. Resident doctors were unsatisfied with clinical practice during the pandemic year, but they positively valued the development of online courses. Learning efficiency improved by repeating the same procedure on preclinical models, as proved by the significant decrease of the working times. E-learning was appreciated as an important component of the new hybrid teaching approach. Reorganization and further emphasis on both preclinical and medical practice, targeted to aid residents perform more accurate and efficient procedures, are recommended.

Introduction. The aim of this study was to assess the results of the impact of the first year of the COVID-19 (coronavirus disease 19) pandemic on the postgraduate hybrid educational process (virtual/e-learning and traditional) from a resident-centred perspective, in a group of general dentistry resident doctors. Materials and methods. A questionnaire with 32 items (Q1-Q32) was configured using Google Forms and filled online, anonymously. In the first section, demographic information was collected. The other sections collected data about: 1) technical support), 2) the impact of traffic restriction and self-isolation, 3) the impact of preclinical/clinical online training compared to the on-site one, 4) attendance of online theoretical courses, 5) the effect of preclinical training in laboratories, 6) the degree of online interactivity and 7) general satisfaction. Excepting demographics and Q1-Q3 items, all other parts used multi-choice responses based on a five-degree Likert scale. Results. Most resident doctors did not report any problem in connection to online courses, increased anxiety, troubled concentration, or decreased learning efficiency. Conclusions. Resident doctors considered part-time e-learning process as a viable approach capable of providing a qualitative education and that the reorganization of the preclinical activity allowed them to carry out more precise and efficient procedures in the clinic.
