Abstract
PINASCO, Laura; ALFIE, Denise; GARCIA, Gonzalo and GOLDBERG, Fernando. Comparative study of the times recorded by the TruNatomy and ProTaper Next instruments to reach the working length in simulated curved canals filled with GuttaCore. Rev. Asoc. Odontol. Argent. [online]. 2021, vol.109, n.2, pp.81-85. Epub Aug 20, 2021. ISSN 2683-7226. http://dx.doi.org/10.52979/raoa.1115.
Aim:
Compare the time required by the instruments TruNatomy Medium and ProTaper Next X3 to penetrate up to the working length the mass of fillings made with GuttaCore Primary and sealant in simulated curved canals.
Materials and methods:
The simulated canals of 20 EndoTraining Blocks were prepared with WaveOne Gold Primary and obturated with GuttaCore Primary and AH Plus. The sample was divided into two groups of 10 each. Group 1: The sealing material was penetrated up to working length with TruNatomy Medium. Group 2: The sealing material was penetrated up to working length with ProTaper Next X3. The penetration time was recorded in each group and the obtained values were statistically analyzed with the Student’s t test.
Results:
ProTaper Next X3 instruments penetrated the sealing material mass faster than TruNatomy Medium. Statistically significant differences were observed between the two instruments (P <0.01).
Conclusion:
While the ProTaper Next X3 and TruNatomy Medium penetrated the GuttaCore mass to the working length efficiently, the ProTaper Next X3 did it in less time.
