An in vitro analytical research was carried out in the general laboratory of the "Carlos Andrade Marín" Hospital. The population consisted of 20 bars of Meta®Biomed brand gutta-percha (Korea) distributed in four groups made up of 5 bars according to the pre-established characteristics in terms of thermoplasticization and handling. Only 15% of the selected samples showed signs of bacterial growth, of which 66.67% belonged to the group of solid gutta-percha bars that were manipulated, establishing specific differences with respect to the rest of the groups (p≤0.01), according to the T-students test. Most of the samples have no evidence of bacterial growth. However, two of the three samples that showed this microbiological activity belonged to the group of solid gutta-percha bars that were manipulated.
