Assistência cirúrgico-odontológica a pacientes com história de infarto do miocárdio

The execution of a appropriate odontological surgical treatment for patients with Myocardial Infarction has been based in established protocols for important works in world wide literature during the sixty’s and seventy’s decade, established with a minimum of six months before the noncardiac surgery. The recent advancements in the medical assessment of surgical risk based on the individual analysis of each case with availability of new therapeutic tools in reference to medical or dental treatment, allowing for new procedures that can be used in the execution of safer odontological surgery for each patients. This review of the literature shows the actual tendencies of the treatment of patients with Myocardial Infarction concerning specific care before, during and after surgery based on laboratory evaluation and drug therapy as well as the possibility of surgical treatment before six months post-infarction.A execução de um plano de tratamento cirúrgico-odontológico adequado em pacientes com história de Infarto do Miocárdio tem sido baseada em protocolos estabelecidos desde as décadas de 1960 e 1970, que estipulavam um período de espera mínimo de seis meses para a execução de cirurgia não-cardíaca. Atualmente, os recentes avanços na avaliação médica do risco cirúrgico com base na análise individual de cada caso, bem como a disponibilidade de novos recursos terapêuticos tanto no que se refere ao tratamento médico quanto odontológico, permitem que novas posturas sejam adotadas na execução de um cirurgia odontológica segura nestes pacientes. Neste trabalho, a partir da revisão de literatura, procurou-se abordar as tendências atuais do tratamento de pacientes com história de infarto agudo do miocárdio, no que se refere aos cuidados específicos durante o pré, trans e pós-operatório, tendo em vista a avaliação laboratorial e terapêutica medicamentosa; bem como na possibilidade de tratamento cirúrgico-odontológico prévio aos seis meses pós-infarto

Effect of root surface treatment with propolis and fluoride in delayed tooth replantation in rats

Replantation is an acceptable option for treatment of an avulsed permanent tooth. Nevertheless, an extended extraoral period damages the periodontal ligament and results in external root resorption. The purpose of this study was to assess by histologic and histometric analysis, the influence of propolis 15% (natural resinous substance collected by Apis mellifera bees from various plants) and the fluoride solution used as root surface treatment on the healing process after delayed tooth replantation. Thirty Wistar (Rattus norvegicus albinus) rats were submitted to extraction of their upper right incisor. The teeth were maintained in a dry environment for 60 min. After this, the pulp was extirpated and the papilla, enamel organ and periodontal ligament were removed with scalpel. The teeth were divided into three experimental groups: Group I - teeth immersed in 20 ml of physiologic saline; Group II - teeth immersed in 20 ml of 2% acidulated phosphate sodium fluoride; Group III - teeth immersed in 20 ml of 15% propolis. After 10 min of immersion in the solutions, the root canals were dried and filled with calcium hydroxide paste and the teeth were replanted. The animals were euthanized 60 days after replantation. The results showed that similar external root resorption was seen in the propolis and fluoride groups. Teeth treated with physiologic saline tended to have more inflammatory root resorption compared with those treated with fluoride or propolis. However, the comparative analysis did not reveal statistically significant differences (P > 0.05) between the treatment modalities when used for delayed tooth replantation
