ABSTRACT Introduction: sodium hypochlorite is considered the most widely used irrigant solution worldwide, its characteristics and low cost make it to be considered the "Gold standard" as a complement for endodontic instrumentation. Objective: io determine the knowledge of dental students in their seventh to tenth semesters regarding the handling and storage of sodium hypochlorite prior to the beginning of their pre-professional internships. Methods: an observational, descriptive, cross-sectional, descriptive study was carried out in the academic period May - September 2022, in students from eighth to tenth semester of the dentistry career of the Regional Autonomous University of the Andes "UNIANDES" on their knowledge about the storage of sodium hypochlorite, as well as the concentrations of preference and the cases in which each one of them would be used. An opinion poll was used to find out the most frequent storage conditions, with five closed and multiple choice questions, the variables used and the results obtained were described statistically by means of percentages. Results: 36,8 % of the students do not store sodium hypochlorite correctly; they use containers that do not protect the irrigant from ambient light. 97,4 % of the respondents have the knowledge about the environmental condition of storage and temperature. There is a discrepancy regarding the concentration that should be used for the instrumentation of pulps with a diagnosis of necrosis, since 50,4 % use higher concentrations (5,25 %) while 42,7 % use 2,5 % irrigant. Conclusions: the research should be complemented with experimental studies in which it can be demonstrated that storage conditions can impair the composition and stability of sodium hypochlorite.
