ObjectiveTo 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%). ConclusionThe 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.

Many patients with this syndrome have compromised oral hygiene, difficulty in addressing dental cases, developmental delay, and autistic behavior. Thus, it is important to pay attention to these early children from an early age and encourage preventive approach.

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.

Ca 3 SiO 5 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 Ca 3 SiO 5 in vivo. Therefore, the goal of this study is to evaluate the genotoxic and mutagenic potential of Ca 3 SiO 5 -based cement in vivo. Twenty-four male Wistar rats were divided into 3 groups (n = 8). Group A rats received subcutaneous implantation of Ca 3 SiO 5 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 Ca 3 SiO 5 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 Ca 3 SiO 5 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 Ca 3 SiO 5 group compared to that of the negative control group (p < 0.05). Our data showed that exposure to the Ca 3 SiO 5 -based cement resulted in an increase in the frequency of micronuclei, but no genotoxicity was detected according to the comet assay.

Osteogenesis imperfecta (OI) is a disease characterized by decreased bone mineral density, causing susceptibility to bone fractures by mild trauma and bone deformities. The aim of this study was to describe an osteogenesis imperfecta type III clinical case, its craniofacial and oral changes as well as its atypical radiographic findings. An eighteen-year-old, male patient diagnosed with osteogenesis imperfecta type III was referred for dental evaluation; the clinical examination showed the craniofacial and oral changes of the disease such as triangular face, class III malocclusion, anterior open bite and posterior crossbite, dentinogenesis imperfecta presenting amber discoloration. The radiographic examination revealed teeth with pulp chamber obliteration and root canals, however unusual findings were also observed such as: bilateral increase of the mandibular canals and preservation of the pulp chamber and third molar root canals. Our findings show that is essential an adequate knowledge of anatomy, a careful anamnestic evaluation and a complete radiological evaluation of the patient with OI. Key words: Dental anomalies, developmental disability, rare disorders.
