O OSCE na avaliação clínica odontológica: relato de experiência com estudantes de graduação / OSCE in Dental clinical evaluation: the report of an experience with undergraduate students

O Exame Clínico Objetivo e Estruturado (OSCE) é um exame organizado em estações que simulam a realidade clínica e os estudantes são avaliados em tarefas específicas como anamnese, exame físico, comunicação com paciente, procedimentos clínicos não invasivos, entre outras. É realizado o rodízio de alunos e um ou dois examinadores pontuam o desempenho dos mesmos em cada tarefa, com critérios e tempo previamente determinados. O objetivo desse estudo foi relatar a experiência de aplicação do OSCE na graduação e como estruturá-lo. O primeiro OSCE aplicado pelo curso de Odontologia da Universidade do Oeste Paulista (UNOESTE) para alunos de graduação foi no ano de 2016, com o objetivo de avaliação de competências dos alunos que ingressariam nas clínicas no semestre seguinte. A avaliação foi aplicada aos 70 alunos do final do terceiro ano e os conteúdos selecionados foram Dentística, Periodontia, Endodontia, Radiologia, Biossegurança, Anestesiologia e Diagnóstico Bucal. O OSCE pode ser considerado uma técnica de avaliação adequada para o alcance de competências clínicas na formação de cirurgiões-dentistas, por proporcionar ao aluno de graduação a vivência de atividades similares à realidade que enfrentará no atendimento clínico e em sua futura atuação profissional. Esse método de avaliação propicia aos estudantes a oportunidade de serem avaliados de forma mais objetiva e poder aprender com o feedback do seu desempenho no exame (AU).

The Objective and Structured Clinical Examination (OSCE) is an exam organized in stations that simulate clinical reality and students are evaluated in specific tasks such as anamnesis, physical examination, communication with patients, noninvasive clinical procedures, among others. Students rotated through stations, and one or two examiners score their performance in each task, with predetermined criteria and time. The objective of this study was to report on the experience of applying the OSCE in undergraduate and how to structure it. The first OSCE applied for Dental undergraduate students at Universidade do Oeste Paulista (UNOESTE) was in 2016, with the objective of evaluating the competencies of the students who would enter the clinics in the following semester. The evaluation was applied to 70 students at the end of the third year and the contents selected were Restorative Dentistry, Periodontics, Endodontics, Radiology, Biosafety, Anesthesiology and Oral Diagnosis. The OSCE can be considered an adequate evaluation technique for the attainment of clinical competences in the training of dental surgeons, as it provides the undergraduate student with the experience of activities similar to the reality he will face in clinical care and his future professional performance. This assessment method gives students the opportunity to be evaluated more objectively and to learn from feedback on their exam performance (AU).

Oral health evaluation of cardiac patients admitted to cardiovascular pre-surgery intervention / Saúde bucal de pacientes cardiopatas internados em pré- intervenção de cirurgia cardiovascular

ABSTRACT Objective: To assess the oral health status of patients admitted to pre-intervention heart surgery, observing the need index concerning invasive treatment. Methods: hospitalized volunteers in number of 75 were evaluated in order to be investigated concerning which systemic changes were occurring, the patients' oral health conditions as well as the need for invasive dental procedures. Results: Volunteers analyzed in the study were: 69.3% male and 30.7% female. As for the reason for hospitalization were: valvuloplasty (41.3%), coronary artery bypass surgery (24%), pacemaker implantation (16%), cardiac catheterization (8%), placement of stent (6.6%), congenital heart disease (4%). The associated systemic changes were: hypertension (54.6%), diabetes mellitus (20.0%), hypertension and diabetes mellitus (13.3%). Most patients presented the need to undergo invasive dental treatment procedures such as: Periodontal (58.6%), Restorative Dentistry (26.6%), surgical (18.6%), endodontic (12%), dental pain source (2, 6%), abscess presence (1.3%). Conclusion: The oral health status of the patients was considered poor, a significant number of patients at the time of the oral examination, needed some type of invasive dental treatment and the oral environment adequacy indicated dental condition which may cause the formation of infectious sites which in turn can trigger complications both in the oral cavity and general health, as well.

Evaluation of the genotoxicity and mutagenicity of Ca3SiO5-based cement.

Ca3SiO5 is new cement based on the composition of Portland that has been developed to have superior physicochemical and biological properties. In a clinical evaluation, the cement did not appear to have cytotoxic properties and allowed for the proliferation of pulp cells and gingival fibroblasts. However, no previous studies have evaluated the genotoxicity or the mutagenicity of Ca3SiO5in vivo. Therefore, the goal of this study is to evaluate the genotoxic and mutagenic potential of Ca3SiO5-based cement in vivo. Twenty-four male Wistar rats were divided into 3 groups (n = 8). Group A rats received subcutaneous implantation of Ca3SiO5 in the dorsum. Group B rats received a single dose of cyclophosphamide (positive control). Group C rats received subcutaneous implantation of empty tubes in the dorsum (negative control). After 24 hours, all animals were euthanized and the bone marrow of the femurs was collected for use in the comet assay and the micronucleus test. The comet assay revealed that the Ca3SiO5 group had a tail intensity of 23.57 ± 7.70%, the cyclophosphamide group had a tail intensity of 27.43 ± 7.40%, and the negative control group had a tail intensity of 24.75 ± 5.55%. The average number of micronuclei was 6.25 (standard deviation, SD = 3.53) in the Ca3SiO5 group, 9.75 (SD = 2.49) in the cyclophosphamide group, and 0.75 (SD = 1.03) in the negative control group. There was an increase in the micronuclei frequency in the Ca3SiO5 group compared to that of the negative control group (p < 0.05). Our data showed that exposure to the Ca3SiO5-based cement resulted in an increase in the frequency of micronuclei, but no genotoxicity was detected according to the comet assay.
