Determinants for traumatic orofacial injuries in sport: Extrinsic factors in a scoping review.

BACKGROUND/AIM: Sports practices carry a risk for orofacial injuries and, to avoid them, preventive measures are necessary. The aim of this study was to investigate a web of extrinsic determinants for orofacial trauma in sports. MATERIALS AND METHODS: Through a scoping review, eight extrinsic risk factors for sports-related orofacial trauma emerged from the thematic analysis. These were sports modality, sports philosophy, competition rules, level of competition, accessory equipment, environmental conditions, acting regimen, pitch conditions, and human resources. The data collection was conducted on seven databases, using terms based on health science descriptors and keywords related to orofacial trauma and sports. RESULTS: From the 1155 articles found, 157 were selected based on eligibility criteria and classified according to the mentioned factors. After the full reading of the articles, the most cited risk factor was sports modality while acting regimen and environmental factors were the least mentioned. Therefore, a scheme following the web of determinants was constructed with the purpose of establishing a risk profile, which was based on the interactions between the determinants and on the frequency that they were mentioned as contributors to injury. From this, it was observed that each traumatic event is possibly a result of the interrelationships among the eight suggested determinants. CONCLUSION: Sports modality was the most cited extrinsic determinant observed in the literature, while environmental conditions and acting regimen were the least cited. In addition, more than establishing the determinants, it is necessary to comprehend how they relate, once preventive strategies should intercede on these relations, to help reduce sports injuries.

Efeito da degradação química e mecânica em resinas compostas convencional e bulk fill / Effect of chemical and mechanical degradation on conventional composite resins and bulk fill

Objetivo: o objetivo do presente estudo é avaliar a degradação da superfície por rugosidade de uma resina composta convencional e duas Bulk Fill armazenadas em bebidas ácidas, após escovação simulada. Materiais e Métodos: foram confeccionados 30 corpos de prova cilíndricos (10 mm x 1 mm) de cada resina: resina FiltekZ350 XT (3M Co., St. Paul), resina Filtek Bulk Fill (3M Co., St. Paul) e resina Tetric N-Ceram (IvoclarVivadent, Schaan, Liechtenstein), totalizando noventa corpos. Os corpos de prova foram imersos em três tipos de bebidas, Coca-Cola, Gatorade de sabor limão e água destilada (controle), por 15 minutos, e após a imersão foram realizadas simulações de escovação por 25 segundos, durante 15 dias. Em seguida, foram submetidos à avaliação de rugosidade de superfície (rugosimetro). Foram realizados os testes estatísticos de Shapiro-Wilk, Kruskal-Wallis e Wilcoxon. Resultados: ao final do experimento foi realizada a análise estatística, e os resultados de rugosidade inicial e final de cada resina de acordo com a bebida foram: Filtek Z350 XT apresentou diferença estatística com grupo controle (p=0,037) e Gatorade (p=0,005). A resina Tetric N-Ceram apresentou diferença estatística para grupo controle (p=0,047) e para Coca-Cola (p=0,007). E a resina Filtek Bulk Fill não houve diferença estatística em nenhuma das bebidas. Conclusão: dentre as resinas estudas, Tetric N-Ceram mostrou um maior aumento da rugosidade superficial quando comparada às outras resinas estudadas. Entretanto, as resinas Bulk Fill mostraram propriedade satisfatória comparada à resina convencional.(AU)

Objective: This study aims to assess the surface degradation through the roughness of a conventional composite resin and two bulk fill resins stored in acidic beverages after simulated brushing. Materials and Methods: Thirty cylindrical specimens (10 mm x 1 mm) of each resin were produced: Filtek Z350 XT (3M Co., St Paul), Filtek Bulk Fill (3M Co., St Paul), and TetricN-Ceram (IvoclarVivadent, Schaan, Liechtenstein), resulting in 90 specimens. The specimens were immersed in three types of beverages: Coke, lemon Gatorade, and distilled water (control), for 15 minutes. After the immersion, they were subjected to brushing tests for 25 seconds, for 15 days. Then, the surface roughness (roughness meter) was analyzed. The Shapiro- -Wilk, Kruskal-Wallis, and Wilcoxon statistical test were performed. Results: At the end of the experiment, the statistical analysis was performed. The initial and final roughness results of each resin according to the beverage were Filtek Z350 presented statistical difference with the control group (p= 0.037) and Gatorade (p = 0.005); the TetricN- -Ceram Bulk Fill resin presented statistical difference for the control group (p = 0.047) and Coke (p = 0.007). The Filtek Bulk Fill resin showed no statistical difference for any of the beverages. Conclusion: Among the resins studied, Tetric-Nceram showed a higher increase in surface roughness than the other resins studied. However, bulk fill resins showed satisfactory properties compared to the conventional resin.(AU)

Técnica semidireta: abordagem prática e eficaz para restauração em dentes posteriores / Semidirect technique: practical and effective approach to restoration in posterior teeth

Introdução: Embora as restaurações diretas tenham boas propriedades mecânicas, quando utilizadas sem indicação em cavidades amplas ficam susceptíveis a fratura e ao desgaste. Nesses casos, o ideal é que sejam feitas restaurações indiretas do tipo inlay ou onlay, entretanto o custo da etapa laboratorial das restaurações indiretas limitam a realização dessa técnica. Para tentar minimizar o custo e melhorar as propriedades da técnica direta existe as restaurações semidiretas. Objetivo: Descrever na forma de Um caso clínico a confecção de uma restauração do tipo onlay pela técnica semidireta. Relato de caso: Paciente compareceu a clínica odontológica para substituição de restauração insatisfatória no elemento 46. O tratamento de escolha foi substituição da restauração de resina composta por uma restauração do tipo onlay. A técnica semidireta foi eleita para confecção da restauração, uma vez que agrega as vantagens das técnicas direta e indireta, com um menor custo operacional e tempo de execução. Conclusão: A técnica semidireta é uma opção de tratamento para restaurações em dentes posteriores, com menor custo para o paciente e pode ser seguramente indicada em cavidades amplas (AU).

Introduction: Although direct restorations have good mechanical properties when used without large cavities indicated they are susceptible to fracture and wear. In such cases, the ideal is that indirect restorations of inlay or onlay type are carried out, however the cost of the laboratory stage of indirect restorations limit the realization of this technique. To attempt to minimize the cost and improve the properties of the direct technique exists semidiretas restorations. Objective: To describe the form of a clinical case the making of a restoration type onlay by semidirect technique. Case report: Patient attended the dental clinic for poor restoration replacing the element 46. The treatment of choice was replacement of the composite resin restoration by a restoration of the onlay type. The semi-direct technique was chosen to construct the restoration as it adds the advantages of direct and indirect techniques with a lower cost and execution time. Conclusion: The semidirect technique is a treatment option for restorations in posterior teeth, with less cost to the patient and can be safely displayed in large cavities (AU).
