JESUS, Renata Patrícia Freitas Soares de et al. Antimicrobial and antiadherent activity ofpithecellobium cochliocarpum (gomez) macbr testedon oral microorganisms. Odontol. Clín.-Cient. (Online) [online]. 2010, vol.9, n.4, pp. 331-335. ISSN 1677-3888.

The dental biofilm is the major factor in the etiology of caries and periodontal diseases. Several plant products have shown to be potentially interesting with regard to its antimicrobial activity. The aim of this study was to evaluate the antibacterial and adherent the ethanol extract of Pithecellobium cochliocarpum (Gomez) Macbr (babatenon) front Streptococcus mutans , Streptococcus sanguinis , Streptococcus salivarius, Streptococcus mitis, Streptococcus oralis and Lactobacillus casei. To determine the minimum inhibitor y concentration (MIC) tests were perfomed in triplicate on solid medium, using the technique of Agar Diffusion in petri dishes relation to determining the minimum inhibitory concentration of adherence (CIMA) of the bacteria to glass in the presence of sucrose at 5%, we used the technique of inclined tubes . In a comparative study, it was determined the CIM and CIMA values of chlorhexidine 0.12%. As for CIM, Pithecellobium cochliocarpum showed antibacterial activity similar to chlorhexidine gluconate against all strains tested. The zones ranged from 10 to 30 mm with outstanding results (up to dilution 1:512) against S. sanguinis, S. oralis and L. casei. Already the CIMA in relation the babatenon was effective in inhibiting adhesion to the last dilution was considered (1:512) for S. sanguinis, S.oralis and S. mitis, showing average performance than chlorhexidine. It is concluded that Pithecellobium cochliocarpum showed significant antimicrobial activity and antiadherent emphasizing the importance of evaluating an agent herbal medicine more accessible to people with perspective of the prescription in primary care services, and in line with new guidelines from the Ministry of Health.
