Alterations in antioxidant defense in obese people with metabolic syndrome can contribute to oxidative stress. This study assessed the relationship between the parameters of metabolic syndrome and the zincemia, activity of superoxide dismutase, and glutathione peroxidase enzymes in obese women. Seventy-three premenopausal women, aged between 20 and 50 years, were divided into two groups: case group, composed of obese (n=37), and control group, composed of no obese (n=36). Analyses of zinc intake, parameters of metabolic syndrome, plasma, and erythrocyte zinc, and activities of superoxide dismutase and glutathione peroxidase were carried out. The mean values of body mass index of obese women and control group were 34.5±3.4 and 21.7±1.9 kg/m2, respectively (p<0.05). In the study, body mass index, waist circumference, and zinc intake were higher in obese women than control group (p<0.05). The plasma zinc and activity of superoxide dismutase did not show significant differences between obese and controls (p>0.05). The values of erythrocyte zinc was 36.4±15.0 μg/gHb and 45.4±14.3 μg/gHb and of glutathione peroxidase was 46.4±19.4 U/gHb and 36.7±13.6 U/gHb in obese women and controls, respectively (p<0.05). The study shows that there are alterations in biochemical parameters of zinc in obese women, with low zinc concentrations in erythrocytes. Regression analysis demonstrates that the erythrocyte zinc and activity of superoxide dismutase enzyme is influenced by components of the metabolic syndrome, and the plasmatic glucose, body mass index, and waist circumference have a negative correlation with this enzyme.

Background: Impacted third molar surgeries are common procedures in clinical practice of dentists and are associated with several trans and postoperative complications. As a result, antibiotic prophylaxis is quite common. Aim: To investigate the scientific evidences regarding the prophylactic prescription of amoxicillin in third molar surgeries in healthy patients. Methods: It was carried out a literature review in the electronic databases SciELO, PubMed, LILACS, and Oviatt Library from December of 2015 to January of 2016, using as descriptors: amoxicillin, antibiotic prophylaxis, dental surgery, and third molar. Results and Discussion: Prophylactic administration of amoxicillin for third molar extraction is controversial in terms of its effectiveness in preventing post-surgical complications given that the scientific evidences about its advantages and disadvantages are still limited. Conclusion: In third molar extraction of healthy patients, amoxicillin given prophylactically should be carefully prescribed.

Introdução: Procedimentos odontológicos realizados em pacientes sob tratamento com drogas anticoagulantes orais estão se tornando cada vez mais comuns. Assim, frequentemente são levantadas questões acerca dos riscos tromboembólicos e de sangramento frente à procedimentos orais invasivos. Objetivo: Revisar as evidências científicas acerca da interrupção da terapia anticoagulante em pacientes em uso de varfarina no contexto de cirurgias orais menores. Métodos: Revisão de literatura nas bases eletrônicas SciELO, PubMed, Lilacs, e Oviatt Library nos meses de janeiro à março de 2016, utilizando como descritores: Anticoagulantes, Varfarina, Cirurgia Odontológica e Hemorragia Bucal. Resultados e Discussão: A continuação da terapia anticoagulante é extremamente importante em pacientes com alto risco ao desenvolvimento de eventos tromboembólicos. A maioria dos estudos mostram que o risco de hemorragia em cirurgias orais em pacientes sob tratamento com varfarina é relativamente pequeno e pode ser controlado por medidas simples de hemostasia. Conclusão: É recomendado que a terapia anticoagulante não seja descontinuada durante a realização de procedimentos cirúrgicos orais menores.

Introduction: Dental treatment performed in patients on anticoagulant drug therapy is becoming increasingly common in dental offices. Thus, questions concerning thromboembolic and bleeding risks relative to invasive dental procedures, are frequently raised. Aim: To review the scientific evidences regarding anticoagulant therapy interruption in patients taking warfarin undergoing oral surgeries. Methods: It was carried out a literature review in the electronic SciELO, PubMed, Lilacs and Oviatt Library databases from January to March of 2016, using as descriptors: Anticoagulants, Warfarin, Oral Surgery, and Oral Hemorrhage. Results and Discussion: Anticoagulant therapy is extremely important in patients at high risk for development of thromboembolic events. Most studies show that the risk of bleeding oral surgery in patients taking warfarin is relatively insignificant and it can be controlled by simple measures such as hemostasis. Conclusion: It is highly recommended to not interrupt anticoagulant in minor oral surgeries.

Introdução: Cirurgias em terceiros molares retidos são procedimentos frequentes na prática clínica odontológica e estão associadas a inúmeras complicações trans e pós-operatórias. Como consequência, a profilaxia antibiótica é comumente relatada. Objetivo: Investigar as evidências científicas acerca da eficácia clinica profilática da amoxicilina em exodontias de terceiros molares retidos em pacientes saudáveis. Método: Realizou-se uma revisão de literatura nas bases eletrônicas SciELO, PubMed, LILACS e Oviatt Library nos meses de dezembro de 2015 a janeiro de 2016, utilizando como descritores: amoxicilina, antibioticoprofilaxia, cirurgia odontológica e terceiro molar ou dente serotino. Resultados e Discussão: A administração profilática da amoxicilina para extração de terceiros molares é objeto de controvérsia no tocante à sua eficácia clínica uma vez que evidências científicas acerca de suas vantagens e desvantagens ainda são limitadas. Conclusão: Em procedimentos cirúrgicos de extração de terceiros molares de pacientes saudáveis, a prescrição profilática da amoxicilina deve ser realizada com cautela.
