According to a study by the University of the Basque Country (UPV / EHU, northern Spain), a large number of bacteria are present in the human mouth and can pass into the bloodstream when 39, interventions such as dental extraction.
Many studies have shown that chlorhexidine rinsing has a potent antimicrobial effect on salivary microflora and bacterial plaque
"Based on this hypothesis, it can be assumed that antimicrobial mouthwashes, used before a dental procedure, should decrease the number of microorganisms introduced into the patient's bloodstream, however, there is great controversy about this aspect, "say members of the UPV / EHU research group. [19659002] The research group, of which they form Iciar Arteagoitia, Carlos Rodriguez Andrés and Eva Ramos, decided to carry out an analysis to evaluate the effectiveness of chlorhexidine in the prevention of bacteremia after tooth extraction. [19659002] The study included 8 clinical trials, with 523 patients: 267 in the group treated with chlorhexidine, with 145 cases of bacteremia, and 256 in the control group, in 156 res
The results of the investigation thus indicate that the percentage of cases of bacteremia that can be avoided if chlorhexidine is avoided is only 12%
. These data show "relative and insignificant efficacy" of the use of chlorhexidine to prevent bacteria in the mouth from entering the bloodstream during tooth extraction.
"However, given 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 ", concludes the research group of the UPV / EHU, whose work was published in Plos One.
