Students' perception to an interactive web-based response system in oral and maxillofacial pathology teaching

Abstract This study evaluated dental students' perceptions and adherence to an interactive web-based response system in the teaching of Oral and Maxillofacial Pathology. Between 2018 and 2019, students from a single Brazilian dental school used the Poll Everywhere® app to answer questions on subjects taught during an Oral and Maxillofacial Pathology course. At the end of the academic semester, the students completed a questionnaire containing 10 questions regarding the app's use. The study included 123 students. Regarding the devices used to answer the questions on the app, 117 (95.1%) students used a smartphone and 3 (2.4%) used a laptop. Almost all students (121; 98.4%) agreed that this interactive web-based response system provided the teacher with a better overview of students' understanding and improved their self-assessment of the acquired knowledge of the subjects. Most students (118; 95.9%) preferred classes using this technology and 122 (99.2%) stated that using the app made them feel more engaged in classes. In addition, all students agreed that the app improved student-teacher interactions. Most students (119; 96.7%) considered the digital interactive method more attractive than the conventional teaching approach, and 99 (80.5%) did not have any negative comments regarding the app. In conclusion, the Poll Everywhere® app provides a more dynamic and attractive educational environment for Oral and Maxillofacial Pathology teaching.

Avaliação do conhecimento de estudantes de odontologia sobre a transmissão e prevenção de infecções sexualmente transmissíveis / Assessment of odontology students' knowledge about the transmission and prevention of sexually transmitted infections

Objetivo: Conhecer o perfil demográfico e comportamento sexual e conhecimento clínico no que se refere à prevenção de IST dos estudantes do 4º ao 10º período do Curso de Odontologia de uma universidade brasileira. Métodos: Tratou-se de um estudo transversal, realizado através da aplicação de um questionário com perguntas sobre aspectos sociais, demográficos, econômicos e relativos às formas de transmissão e expressão clínica de IST. Os dados foram analisados descritivamente (médias, medianas, desvio padrão), assim como também foi realizada a análise estatística inferencial, com nível de significância de 5%. O programa utilizado para executar as inferências foi o SPSS, versão 23. Resultados: Constatou-se, preliminarmente, predominância de brancos entre os entrevistados, baixo uso de preservativos nas relações sexuais, altos índices de realização de teste para detecção de HIV e falhas no conhecimento em identificar IST passíveis de transmissão durante o atendimento odontológico. Conclusão: Há falhas no aprendizado do público-alvo da pesquisa, refletindo em desconhecimento sobre a prevenção, transmissão, sinais e sintomas de IST que envolvam a boca e seus anexos.

Aim:To know the demographic profile, sexual behavior, and clinical knowledge regarding STI prevention of students from the 4th to 10th period of the Dentistry Course at a Brazilian university. Methods: This was a cross-sectional study, carried out through the application of a questionnaire with questions about social, demographic, economic aspects and related to the transmission and clinical expression of STIs. Data were analyzed descriptively (means, medians, standard deviation), as well as inferential statistical analysis, with a significance level of 5%. The program used to perform the inferences was SPSS, version 23. Results: This study primarily found a predominance of whites among the interviewees, a low use of condoms in sexual relations, high rates of testing for HIV detection, and flaws in students' knowledge in identifying STIs capable of transmission during dental care. Conclusion: There are gaps in learning within the research target audience, reflecting a lack of knowledge about the prevention, transmission, signs, and symptoms of STIs involving the mouth and its attachments.

Awareness of patients receiving bisphosphonates: a cross-sectional study

Abstract The aim of this study was to evaluate the awareness of patients using bisphosphonates (BP) regarding their risks and benefits. Sixty-five patients using BP were included. Each participant completed a self-administered questionnaire consisting of 13 questions, including sociodemographic and general information on BP. Data were analyzed using descriptive statistics, and a binomial test was used to assess patient knowledge about BP, considering a 5% significance level. Fifty-nine (90.2%) patients were unaware or had never heard of BP drugs and only 3 (4.6%) knew their indications. Only 6 patients (9.2%) said they knew about the oral complications caused by BP. Sixty-three patients (96.9%) said they were not referred to the dentist before starting BP treatment. Patients using BP do not have satisfactory knowledge regarding the risks and benefits of BP. Physicians and dentists must be prepared to inform and counsel BP users about their adverse effects and possible risk factors. Our results emphasize the importance of public policies, whether individual or collective, to be taken to increase knowledge about BP to avoid medication-related osteonecrosis of the jaw.

Neoplasias orofaciais em crianças e adolescentes / Orofacial neoplasms in children and adolescents

Objetivo:Este trabalho analisou os casos de neoplasias orofaciais em crianças e adolescentes, diagnosticadas pelo Laboratório de Patologia Oral da Universidade Federal de Pernambuco no período de março de 2000 a março de 2019. Métodos: Tratou-se de um estudo retrospectivo das neoplasias mais prevalentes diagnosticada no serviço. Os dados foram tabulados e analisados através do programa Statistical Package for the Social Sciences(SPSS) na versão 24.0. Resultados:Dos 6.766 casos diagnosticados, 101 foram de neoplasias, destes 52,5% foram no sexo feminino. A média de idade entre os pacientes foi de 12,6 anos. Em relação ao tipo de biópsia, a excisional foi mais prevalente e em 71,3% dos casos os diagnósticos histopatológicos confirmaram as hipóteses diagnósticas clínicas. A neoplasia benigna não odontogênica mais comum foi o papiloma oral com 30 casos (29,7%). Entre os tumores benignos de origem odontogênica, os odontomas foram os mais prevalentes com 16 casos (15,8%). Foram diagnosticados apenas dois tipos de neoplasias malignas: o carcinoma adenoide cístico e o leiomiossarcoma. Conclusão:Levantamentos epidemiológicos de lesões orofaciais são importantes para determinar a sua prevalência, além de contribuir com a determinação das características na população estudada, fornecendo ao cirurgião-dentista uma base sólida para o diagnóstico e manejo clínico das neoplasias nesses indivíduos.

Aim:To analyze the cases of orofacial neoplasms in children and adolescents, diagnosed by the Oral Pathology Laboratory of the Federal University of Pernambuco from March 2000 to March 2019. Methods: Treatment of a retrospective study of the most prevalent neoplasms diagnosed at the laboratory. Data were tabulated and analyzed using the Statistical Package for Social Sciences (SPSS), version 24.0. Results:Of the 6,766 cases diagnosed, 101 were neoplasms, 52.5% of these were not female. The average age among the patients was 12.6 years. Regarding the type of biopsy, tooth extractions were more prevalent, and in 71.3% of the cases, the histopathological diagnoses confirmed the clinical diagnostic hypotheses. The most common non-odontogenic benign neoplasm was the oral papilloma, found in 30 cases (29.7%). Among the benign tumors of odontogenic origin, the odontomas were the most prevalent in 16 cases (15.8%). Only two types of malignant neoplasms were diagnosed: adenoid cystic carcinoma and leiomyosarcoma. Conclusion:Epidemiological surveys of orofacial lesions are important to determine their prevalence and aid in defining the characteristics in the studied population, providing the dentist with a continuous basis for the diagnosis and clinical treatment of neoplasms in these individuals.

Oral squamous cell carcinoma: a clinicopathological study on 194 cases in northeastern Brazil. A cross-sectional retrospective study

ABSTRACT BACKGROUND: Only a few studies have evaluated the clinicopathological features of oral squamous cell carcinoma (SCC) in Brazil, and most were conducted in the most industrialized region of the country, i.e. the southeastern region. The aim of this study was to evaluate the clinicopathological features of this malignant neoplasm in northeastern Brazil. DESIGN AND SETTING: Retrospective study performed in an oral pathology laboratory in Recife, Brazil. METHODS: All cases of oral SCC that occurred between 2000 and 2015 were studied. Clinical data were recorded and histological slides were reviewed. Statistical analysis was performed using the chi-square test (P ≤ 0.05). RESULTS: A total of 194 cases were evaluated. The male-to-female ratio was 1.5:1. The mean age was 65.4 years, and only 6.6% of the cases occurred in patients younger than 41 years. Most tumors consisted of well-differentiated SCC (54.6%). CONCLUSIONS: The findings of this study highlight the higher prevalence of oral SCC among women and the increasing number of cases among young patients. Thus there is no specific risk group for oral SCC, as in the past. This fact needs to be taken into consideration in clinical routine care, so that apparently innocuous malignant lesions do not go unnoticed in these individuals.

Incorporação da técnica de restauração atraumática por equipes de saúde bucal da atenção básica à saúde do Recife/PE / Incorporation of the atraumatic restoration technique by oral health teams from the basic health care of Recife/PE

Resumo: Objetivou-se analisar aspectos referentes ao emprego da Técnica de Restauração Atraumática (TRA) nas atividades dos Cirurgiões-Dentistas (CDs) da Atenção Básica à Saúde (ABS) do Recife, no Distrito Sanitário IV, planejadas para o controle e tratamento da cárie dentária. Promoveu-se uma caracterização do perfil profissional e sobre aspectos relacionados ao emprego da técnica. Tratou-se de um estudo observacional de caráter descritivo. A amostra foi o universo dos CDs (23), que estavam em exercício profissional em 23 unidades de saúde do Distrito Sanitário IV, no primeiro semestre de 2017. Para a coleta de dados foi elaborado um questionário estruturado submetido à validação e foi aplicado face a face. A análise de dados realizou cálculos de estatística descritiva. Foram calculadas a distribuição de frequência absoluta e relativa das variáveis estudadas. Apenas dois dentistas não foram entrevistados por estarem afastados do trabalho, isto significou em uma perda de 8,69%. Prevaleceu entre os entrevistados a idade de 41 a 57 anos (52,83%); e o sexo feminino (80,95%); 80,95% ingressaram na ABS por concurso; 90,48% possuíam pós-graduação, sendo 80,95% na especialidade Saúde da Família. A maioria afirmou utilizar a TRA e que a ABS recomenda o uso (85,75%). A técnica era utilizada para restaurações provisórias e definitivas (61,11%) e quase 50% dos entrevistados relataram que a qualidade do produto interferia na execução, duração e adesão das restaurações. Os CDs indicaram a TRA para diferentes idades e condições de vida, onde prevaleceu o uso para crianças (42,86%) e gestantes (42,86%). A grande maioria dos CDs se declarou habilitado, mas com necessidade de capacitação (95,24%). Conclui-se que a TRA é indicada e está incorporada às práticas de cuidados da maioria dos entrevistados, contudo investimentos em educação permanente dos profissionais e provimento de material recomendado para o uso eficaz da técnica devem ser planejados.

Hydrogel of polysaccharide of sugarcane molasses as carrier of bone morphogenetic protein in the reconstruction of critical bone defects in rats

PURPOSE: To evaluate the benefit of using carriers such as the biopolymer gel (hidrogel of polysaccharide of sugarcane molasses) associated with the bone morphogenetic proteins (BMP's) in the repair of critical bone defects in calvaria of Wistar rats. METHODS: Forty-two rats were submitted to a surgical calvaria bone defects. These animals were divided into two experimental groups, positive control group and negative control group. The Group I the calvaria defect was filled up with biopolymer gel, biological membrane, BMP and lyophilized graft. The Group II was treated with biopolymer gel, BMP and lyophilized graft. And the group III (positive control group) was treated with BMP, lyophilized graft and biological membrane. In the negative control group (Group IV) a defect was made in the rat calvaria and the animals were sacrificed immediately after the surgery. The animals of experimental groups and positive control group were slaughtered after subsequent periods of 90 and 180 days. In these periods, the histological analysis and image assessment by cone bean tomographic imaging were obtained. RESULTS: There was highest bone tissue formation with statistically significant results in the groups that associated biopolymer gel and membrane (Group I), followed by the group III (BMP, lyophilized graft and biological membrane). The lower bone formation occurred in the group not using the sugarcane biopolymer gel (Group II). The radiolucent areas of the analyzes of 180 days among the groups studied were respectively, 14.98 mm², 26.65 mm² and 35.81 mm². CONCLUSION: The biopolymer gel showed to be an excellent bone morphogenetic protein carrier, probably by facilitating the controlled release of these proteins in the process of bone repair.
