【 摘 要 】

The aim of this study was to evaluate in vitro antimicrobial activity of Myrciaria cauliflora (Mart.) O. Berg., Myrtaceae leaves extract on: Streptococcus mitis (ATCC 903), Streptococcus mutans (ATCC 25175), Streptococcus sanguinis (ATCC 15300), Streptococcus oralis (ATCC 10557), Streptococcus salivarius (ATCC 7073) and Lactobacillus casei (ATCC 9595). The study was done using laborious bacteriological techniques. The assays were made through dilution in agar diffusion method in order to reach the Minimum Inhibitory Concentration (MIC) determination. The results obtained were transferred for database and had the statistics parameter calculated by SPSS program 13.0 version. The t-Student test was used with 5% of significance. In comparative study, the digluconate of chlorexidine (0,12%) was determinated. The leaf extract of Myrciaria cauliflora Berg. formed halos of inhibition oscillating between 10-18 mm of diameter and it showed middle performance significantly inferior in respect to digluconate of chlorexidine (0,12%), on the pure extract and in the concentrations 1:2 and 1:4. It follows that, the Myrciaria cauliflora Berg. extract produced a significative in vitro bactericidal activity on the former oral biofilm bacterias, that suggests the use of these substances as an economic and viable kind of alternative to the control of odontological diseases.
