More Caution Needs in Study Design and Method Selection for “In vitro Antibacterial Effect of Deconex and Sodium Hypochlorite Against Bacterial Taxa Isolated from Dental Units” [Response to Letter]

摘要

We thank Emami and colleagues for their interest in guiding us to their recentlypublished study reporting “In vitro antibacterial effect of deconex and sodiumhypochlorite against bacterial taxa isolated from dental units”.1 We haveattempted to answer their queries as much as possible. Deconex is the predominantagent used in our dental units for many years, hence, we evaluated healthstaff performance in dental faculty. Also in our introduction and results recommendedthe deconex was strong to eliminate microorganisms, thus this disinfectionagent is confirmed. According to the results obtained in this study, there aresome technical errors were happened by the dental technician in the decontaminationprocedure. Therefore, it is necessary to re-inspection and improve themethods of decontamination and the use of appropriate concentrations of thisproduct. Actually, in this research, we criticize the function of the dental technicianin the decontamination routinely procedure, not the efficacy of deconex.Can it be said that antibiotics are approved by CLSI? Is not it necessary tomeasure antibiotic resistance? Of course not. The evaluation of microbial contaminationof dental units and quality control of health workers is the subjectrecommended by the American Dental Association. Emami and his colleagueshave used the term “resistance against alcoholic-based disinfectants”. If the wordis incorrect then it should be used “tolerance to an alcohol solution”.
