Mouthwashes, which use chlorhexidine, have limited efficacy to prevent infections during oral interventions but given their low cost and the absence of adverse reactions and from complications, it is best to use these mouthwashes. According to research conducted by the University of the Basque Country (UPV / EHU, northern Spain), a large number of bacteria are present in the human mouth and can enter the bloodstream when interventions such as l & rsquo; [19659003] Many studies have shown that chlorhexidine rinsing has a strong antimicrobial effect on salivary microflora and bacterial plaque .
"On the basis of this hypothesis, it can be assumed that antimicrobial mouthwashes ] before a dental procedure the number of microorganisms introduced into the patient's bloodstream should decrease, however, members of the UPV / EHU research group have made a great controversy.
The research group, to which belongs Iciar Arteagoitia, Carlos Rodriguez Andrés and Eva Ramos, decided to carry out an analysis to evaluate the effectiveness of chlorhexidine in the prevention of bacteraemia after tooth extraction
The study includes 8 clinical trials, with 523 patients: 267 in the chlorhexidine-treated group, with 145 cases of bacteremia, and 256 in the control group, in which there were 156 cases of bacteremia.
The results of the investigation indicate, therefore, that the percentage of cases of bacteremia that can be avoided if prevention with chlorhexidine is made is only 12% .
These data show " relative and insignificant efficacy " of the use of chlorhexidine to prevent bacteria present in the mouth from entering the body. Blood circulation during a tooth extraction.
"However, considering its low cost and the absence of adverse reactions and complications, we consider that it is advisable to rinse with chlorhexidine, before performing an intervention of this type". UPV / EHU research group, whose work has been published in Plos One.
