The aim of this study was verify the utilization and form of storage of sodium hypochlorite solution employed during mechanical chemical preparation of root canals by dentists. A questionnaire was prepared and individually delivered to each professional, totaling 350 interviews. Only participated of the research dentists graduated which realized endodontic treatment. Was verified that 99,42% of interviewed professionals use sodium hypochlorite solution for irrigation of root canals, being that the concentration more used was 1%. Was also observed that solution is acquired by the majority of the professionals in dental houses, kept in white plastic bottles and in ambient temperature. Due high instability of the sodium hypochlorite solutions, fits to the dentists to be acquired knowledge of the correct form of storage of the sodium hypochlorite solutions, what can minimize the loss of free chlorine to increase the effectiveness of the solution.

Features of the packages were also described.ResultsThe lowest losses of active chlorine tenor of the brands were Tubarão, G. Barbosa, Brilux and QBoa. The product with higher pH was Brilux brand. Concerning microbiological tests, the brands showed antimicrobial activity against the strains tested, except three of them that were ineffective against B. subtilis, S. aureus and E. faecalis. When examining the packaging, it was realized that 10 did not have proper packing.Conclusion Most of the solutions of sodium hypochlorite marketed in Aracaju / SE presented as inadequate to their chemical and microbiological properties tested in this study.
