RESUMO

Objetivo: avaliar, através de um questionário, o conhecimento dos alunos de graduação do curso de Odontologia na Universidade Veiga de Almeida sobre avulsão dentária. Material e métodos: um questionário estruturado com formação acadêmica, experiências prévias no assunto, e questões de múltipla escolha sobre o conhecimento de avulsão dentária foi aplicado nos alunos do 2° ao 8° período. Resultados: verificou-se que 98,2% sabem o que é avulsão dentária e 54,5% já estudaram ou tiveram algum tipo de instrução sobre o assunto, 92% responderam que o reimplante dental é o melhor procedimento em caso de avulsão. No entanto, apenas 31% sabem como proceder e o correto cuidado com o dente avulsionado (41%). Em relação ao armazenamento do dente, 61% armazenariam em frasco com leite fresco. 81% dos participantes acreditam que o dente avulsionado, após reimplantado, deve ser imobilizado. Conclusão: os alunos de graduação em Odontologia da Universidade Veiga de Almeida apresentam conhecimento sobre a definição de avulsão dentária e que o reimplante é a melhor opção para o tratamento. Porém observa-se que diante dos cuidados com o dente avulsionado e o protocolo de atendimento, o conhecimento dos alunos é escasso

Objective: to evaluate, through a questionnaire, the knowledge of undergraduate students of dentistry at Veiga de Almeida University about dental avulsion. Material and Methods: a structured questionnaire with academic background, previous experience on the subject, and multiple choice questions about knowledge of tooth avulsion was applied to undergraduate students of dentistry from the 2nd to the 8th semester. Results: 98.2% of students knew what is dental avulsion and 54.5% have studied or had some kind of education on the subject, 92% answered that dental replantation is the best procedure in case of avulsion. However, only 31% effectively knew how to proceed and proper care of the avulsed tooth (41%). Regarding tooth storage, 61% would store in a bottle of fresh milk. 81% of participants believe that the avulsed tooth, after reimplantation, should be immobilized. Conclusion: undergraduate dentistry students at Veiga de Almeida University present knowledge about the definition of tooth avulsion and that replantation is the best option for treatment. However, it is observed that due to the care of the avulsed tooth and the care protocol, students' knowledge is scarce

RESUMO

BACKGROUND: The understanting of the dental fluorosis process, that begins with enamel maturation, is important to Dentistry students, since fluoride has drastically decreased the incidence of caries in several population groups, with a resultant increase in fluorosis prevalence and severity, as shown in literature. AIMS: The objective of this paper is to report the changes in the level of knowledge about dental fluorosis of undergraduate Dentistry students at Guarulhos University. SUBJECTS AND METHODS: One hundred and twenty-four undergraduate students enrolled in the first and second semester (2008) and seventh semester (2008) were evaluated. The data was obtained through questionnaires with dichotomic questions (true and false) and an alternative to evaluate whether the subject had been presented in the classroom. The data obtained was submitted to statistical analysis using the Chi-square test (α=0.05). RESULTS: When evaluating the first semester students, differences were verified in numbers of the questions assigned with the alternatives true or false, when compared with seventh semester students (p<0.001). However, there were no differences when the same questionnaire was applied to the first semester students after six months (p=0.358). CONCLUSIONS: It is possible to conclude that the six months period was insufficient to increase the level of knowledge about dental fluorosis, and when the students beginning and concluding the dentistry course were compared, there was an increase in the number of correctly assigned true or false questions in the latter group.
