ABSTRACT
Abstract This review aimed to assess the association between overweight/obesity and dental caries in Brazilian children/adolescents. Searches were performed in the Web of Science, Scopus, Cochrane, PubMed, Embase and SciELO, Lilacs and Open Grey literature databases up to June 2022. The Joanna Briggs Institute checklist for analytical cross-sectional studies, the checklist for cohort studies, and the checklist for case-control studies were used. A total of 41 publications were included, and 15 meta-analyses were performed. The authors analyzed the differences in weighted mean difference (MD) and odds ratios (OR), and their corresponding confidence intervals (CI) (95%) for dental caries among eutrophic and obese and/or overweight children/adolescents. Meta-analyses showed that there was no association between overweight and/or obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI (Body Mass Index). A greater experience of dental caries was associated with well-nourished adolescents in permanent dentition, compared with obese individuals in the same dentition, as classified by the CDC 2000 curve (OR = 2.53, 95% CI;1.49-4.29; p = 0.0006; I2 = 0%) in dichotomous outcome studies, and (MD = 0.61, 95%CI: 0.08-1.15; p = 0.02; I2 = 0%) in continuous studies. The strength of the evidence of the results was classified as very low, low or moderate. It was concluded that there is no association between overweight and/or obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI. A greater experience of dental caries was associated with well-nourished adolescents in permanent dentition, compared with obese individuals in the same dentition, as classified by the CDC 2000 curve.
ABSTRACT
Introdução: As desordens potencialmente malignas (DPM) são condições da cavidade oral que apresentam risco significativo para o desenvolvimento do câncer. Desse modo, o diagnóstico precoce torna-se essencial no prognóstico de lesões orais. Para isso, analisar o perfil de conhecimento acerca dessas desordens é fundamental ao identificar lacunas na educação e promover alternativas para melhorar a qualidade no diagnóstico. Objetivo: Avaliar a percepção de cirurgiões-dentistas (CDs) e estudantes de Odontologia brasileiros acerca de seu conhecimento e capacidade de identificar DPM. Métodos: Foi realizado um estudo transversal através de aplicação de questionário online. Foram aplicados dois questionários com 24 questões, um para estudantes e outro para CDs, divididos em três seções: dados demográficos e acadêmicos, treinamento, atitudes e autopercepção sobre DPM e conhecimento de DPM. A análise estatística envolveu os testes de Pearson, Mann-Whitney e Kruskal-Wallis. Resultados: O estudo foi composto por 209 participantes, 76 CDs e 133 estudantes de odontologia. A maioria dos participantes nunca realizou curso que envolvia o diagnóstico de desordens potencialmente malignas. A pontuação sobre o conhecimento de DPM variou de 0 a 10 pontos, sendo a média entre estudantes de 6,29±1,77 e entre CDs de 7,01±1,82. A maior taxa de acertos foi para as questões que discutiam a conduta clínica e a definição das desordens. Já as questões com menor taxa de acertos foram sobre lesões que não são consideradas potencialmente malignas, potencial de malignização e definição de Carcinoma in Situ. Conclusão: Há lacunas no conhecimento de estudantes de odontologia e CDs na identificação das desordens potencialmente malignas. Logo, essa deficiência reforça a necessidade de mais treinamentos e investimentos em educação, bem como de acompanhamento periódico de pacientes com tais desordens, a fim de prevenir potenciais transformações malignas.
Introduction: Potentially malignant disorders (PMD) are conditions of the oral cavity that present a significant risk for the development of cancer. Thus, early diagnosis becomes essential in the prognosis of oral lesions. Therefore, assessing the knowledge profile of these disorders is essential to identify gaps in education and to promote alternatives to improve the quality of their diagnosis. Objective: Evaluate the perception of brazilian dentists and dental students about their knowledge and ability to identify PMD. Methods: A cross-sectional study was carried out using an online questionnaire. Two questionnaires with 24 questions were applied, one for students and other for dentists, divided into three sections: demographic and academic data, training, attitudes and self-perception about potentially malignant disorders and knowledge of potentially malignant disorders. Statistical analysis involved Pearson, Mann-Whitney and Kruskal-Wallis tests. Results: The study consisted of 209 participants, 76 dentists and 133 dentistry students. Most participants never attended a course that involved the diagnosis of potentially malignant disorders. The score of knowledge about potentially malignant disorders ranged from 0 to 10 points, with a mean of 6.29±1.77 among students and 7.01±1.82 among dentists. The highest rate of correct answers was for questions that discussed clinical management and the definition of disorders. The questions with the lowest rate of correct answers were about lesions that are not considered potentially malignant, malignancy potential and the definition of Carcinoma in Situ. Conclusion: There are gaps in the knowledge of dental students and dentists in the identification of potentially malignant disorders. Therefore, this deficit reinforces the needed of more training and investments in education, as well as more training and investments in education and periodic follow-up of patients with such disorders are needed in order to prevent potential malignant transformations.
ABSTRACT
O osteoblastoma é um tumor frequentemente visto em ossos longos, com pouco envolvimento maxilofacial e raramente localizado em osso zigomático. Devido à sua semelhança clínica e histológica com outros tumores ósseos, o osteoblastoma representa um desafio de diagnóstico para o profissional. A ressecção cirúrgica total é recomendada, sendo que a ausência de recidiva se deve ao diagnóstico correto e tratamento adequado. O objetivo deste artigo é relatar o manejo de um paciente com osteoblastoma envolvendo o osso zigomático e realizar uma breve revisão da literatura.
Osteoblastoma is a tumor often seen in long bones, with little maxillofacial involvement and rarely located in zygomatic bone. Due to its clinical and histological similarity with other bone tumors, osteoblastoma represents a diagnostic challenge for the professional. Total surgical resection is recommended, and the absence of recurrence is due to correct diagnosis and adequate treatment. The aim of this article is to report the management of a patient with osteoblastoma involving the zygomatic bone and to carry out a brief review of the literature.
