AVALIAÇÃO DAS ATIVIDADES ANTIMICROBIANA E BIOLÓGICA DO CIMENTO PORTLAND ASSOCIADO AO AH PLUS EM DIFERENTES PROPORÇÕES Evaluation of antimicrobial and biological activities of Portland cement associated of AH Plus sealer in different proportions
2014
Introduction: Endodontics has been suffering a long evolution process in recent years. Despite this great technical and scientific developments, unfortunately the conventional endodontic treatment hasn’t allows obtaining the total success. Objective: the objective of the present study was to evaluate the antimicrobial activity and the response of the subcutaneous tissue against deployment of associated Portland cement to AH Plus sealer in different proportions. Methodology: for evaluation of biological response, 42 rats were used (Rattus Norvegicus), which were divided into 14 animals for each experimental period. To evaluate antimicrobial activity, was used the technique of radial diffusion in MuellerHinton agar plates. 30 field strains were used and 1 ATCC (29212) of Enterococcus faecalis. The materials were provided by weight and pits filled with the cements through syringes Luer-type Look. With data, they were subjected to statistical analysis, using the Kruskal-Wallis test for global comparison and the Miller test for individual comparisons with a significance level of 5. Results: as for biological response, all groups showed good behavior. In relation to antimicrobial activity, groups 4, 5 and 6 showed activity in both
