Dental trauma with intrusive luxation and six-year monitoring: clinical case report / Traumatismo dentário com luxação intrusiva com acompanhamento de seis anos: relato de caso clínico

Objective: this study is designed to report a clinical intrusion case, which exhibited enamel hypoplasia on the crown of tooth 11 and which underwent clinical and X-ray monitoring for six years. Case report: A threeyear- old female patient exhibited intrusion of deciduous teeth 51, 52, 61, and 62. After X-ray, it was detected that teeth 51 and 61 had perforated the nasal cavity floor, but all four teeth had re-erupted and began to be monitored. After six months, teeth 51 and 61 exhibited bone loss in the interproximal area, as well as mobility, which led to tooth extraction. Teeth 52 and 62 re-erupted in a satisfactory position, and exhibited no signs and symptoms of infection, periapical alteration, or mobility. These teeth were therefore maintained in the arch. After six years, it was detected that tooth 11 had erupted with enamel hypoplasia. Final considerations: Longterm clinical and X-ray control proved essential, as it allowed for the early diagnosis of potential alterations, and minimized potential sequelae to the permanent teeth.(AU)

Objetivo: relatar um caso clínico de intrusão com acompanhamento clínico e radiográfico de 6 anos, que apresentou hipoplasia de esmalte na coroa do dente 11. Relato de caso: paciente de 3 anos, sexo feminino, apresentou intrusão dos dentes decíduos 51, 52, 61 e 62. Após radiografia, foi detectado que os dentes 51 e 61 tinham perfurado o soalho da fossa nasal, porém, ocorreu re-erupção dos 4 dentes e foi realizado acompanhamento. Após 6 meses, nos dentes 51 e 61, foram observadas perda óssea na região interproximal e mobilidade, optando-se pelas exodontias. Os dentes 52 e 62 re-erupcionaram em posição satisfatória e com ausência de sinais e sintomas de infecções, alterações periapicais e mobilidade, sendo mantidos no arco. Após 6 anos, foi observado que o dente 11 erupcionou apresentando hipoplasia de esmalte. Considerações finais: mostrou-se essencial o controle, clínico e radiográfico, em longo prazo, diagnosticando precocemente possíveis alterações e minimizando sequelas que podem acometer os dentes permanentes.(AU)

Avaliação dos Efeitos da Educação em Saúde sobre o Conhecimento e Comportamento de Higiene Bucal de Escolares / Evaluation of the effects of health education on oral hygiene knowledge and behavior of schoolchildren

Objetivo: Avaliar a eficácia de uma atividade de educação em saúde bucal realizada na Escola de Ensino Fundamental Nemésio Bezerra no Município de Quixadá ­ Ceará sobre o conhecimento e o comportamento de higiene bucal de escolares. Material e Métodos: Foi realizado um estudo descritivo e prospectivo com abordagem quantitativa. A amostra na primeira etapa foi de 86 escolares de 12 a 16 anos e de 79 na segunda etapa do estudo. Na primeira etapa do estudo, foi aplicado um questionário estruturado antes da atividade educativa e na segunda etapa, o questionário foi aplicado um mês depois, com a finalidade de avaliar se ocorreu mudanças nos hábitos e conhecimentos sobre a saúde bucal dos alunos. Os dados coletados por meio dos questionários foram submetidos à análise estatística descritiva. Resultados: Antes da atividade educativa, somente 78% (n=67) dos alunos tinham ouvido falar em saúde bucal, enquanto um mês depois, 96% (n=76) dos estudantes responderam já terem ouvido falar. Antes da atividade educativa, somente 17% (n=15) dos estudantes responderam que a hora mais importante de escovar os dentes era antes de dormir. Depois de um mês, aumentou 43% (n=34). Conclusão: Após a atividade proposta, verificou-se um aumento expressivo na quantidade de alunos que melhoram seu conhecimento e seus hábitos de saúde bucal. O estudo mostra o quão importante se configuram as atividades de promoção de saúde bucal que podem ser capazes de proporcionar mudanças consideráveis no perfil de saúde e na qualidade de vida das populações.(AU)

Objective: To evaluate the efficiency of an oral health education activity carried out at Nemésio Bezerra Elementary School in the city of Quixadá - Ceará on oral hygiene knowledge and behavior of school children. Material and Methods: We carried out a descriptive and prospective study with a quantitative approach. The sample in the first stage was 86 students aged 12 to 16 years and 79 in the second stage of the study. In the first stage of the study, a structured questionnaire was applied before the educational activity and in the second stage the questionnaire was applied one month later with the purpose of evaluating if there were changes in the habits and knowledge about the oral health of the students. The data collected through the questionnaires were submitted to descriptive statistical analysis. Results: Before the educational activity, only 78% (n = 67) of the students had heard about oral health, while a month later, 96% (n = 76) of the students answered they had heard. Before the educational activity, only 17% (n = 15) of the students answered that the most important time to brush their teeth was before bed. After one month, it increased 43% (n = 34). Conclusion: After the proposed activity, there was an expressive increase in the number of students who improved their knowledge and their oral health habits. The study shows how important are the activities of oral health promotion that may be able to provide considerable changes in the health profile and quality of life of populations.(AU)

Assessment of Extruded Debris in Primary Molars Comparing Manual and Reciprocating Instrumentation

Objective: To compare the amount of extruded debris in primary molars after manual instrumentation or WaveOne system. Material and Methods: Twenty-five primary molar roots with mild and moderate root angulation (between 10 to 20º), having at least two thirds of root length, no pathological reabsorption (internal or external) or furcation perforation, were selected for this study. Roots were standardized at 6 mm in length, inserted and stabilized in individual acrylic resin blocks with random distribution into two groups: G1 (n=12): Instrumentation with crown-down manual technique; and G2 (n=13): instrumentation with WaveOne system. Blocks with roots were weighed before and after instrumentation, allowing the calculation of extruded debris using both mechanical preparations. Data analysis was performed by Bioestat 4.0 statistical software using Mann Whitney test. Results: The mean weight of extruded debris in manual instrumentation and WaveOne system have no significant difference (p=0.8704). Conclusion: Manual crown-down instrumentation or WaveOne system does not influence the amount of extruded debris after mechanical preparation, suggesting that both techniques were effective in canals clean causing similar extrused debris, however more studies with largest sample should be done to better validate this evidence.
