Resistance flexion of gutta-percha cones after immersion in natural disinfectants

Objectives: The objective of this study was to compare the resistance flexion of gutta-percha cones after immersion in commercial disinfectants products and natural disinfectants (extracts plants).
Methods: The design of study was experimental in vitro. We used gutta-percha cones of manual type and dimension 40. Four groups of propolis, aloe, sodium hypochlorite and the control group were evaluated. The cones were submerged according to the protocol for five minutes in each four disinfectants group. We measured the flexion with the universal test machine (Digital Testing Machine CMT-5L - Mitutoyo), used with 0.75 mm / min of speed.
Results: Results show a mean of 16.66 Newton for aloe group, 16.49 Newton for sodium hypochlorite and the lowest value was obtained for propolis group with 15.75 Newton. No significant differences were found between the groups with a p> 0.05 when using Kruskall Wallis test.
Conclusions: In conclusion the use of solutions based on aloe and propolis does not affect the flexibility property of gutta-percha cones for endodontic use.
