    Effect of NaOCl solution on the cyclic fatigue resistance of traditional and heat-treated file systems
    (2019) Ertugrul, Ihsan Furkan
    Aim: To compare the cyclic fatigue resistance at distilled water and %5.25 NaOCl of immersed ProTaper Gold (Dentsply Sirona, Ballaigues, Switzerland) and ProTaper Universal (Dentsply Sirona, Ballaigues, Switzerland) file systems.Material and Methods: The ProTaper Gold F2 (25.06v taper) and ProTaper Universal F2 (25.06v taper) file systems were immersed in distilled water andNaOCl for 5 minutes. After immersion process files were rotated at artificial canal with 60O curvature and a 5-mm radius until fracture occurred. Time to fracture and fractured lengths were recorded. Data were analyzed statistically using independent t-tests. Statistical significance was set at P .05. Results: ProTaper Gold files had a significantly higher resistance to cyclic fatigue than ProTaper Universal files (P .05). When ProTaper Universal immersed in distilled water showed higher resistance to cyclic fatigue than immersed in NaOCl solution (P .05).Conclusion: ProTaper Gold system more resistant than ProTaper Universal system to cyclic failure. The effect of NaOCl were higher on the ProTaper Universal system.Keywords: Corrosion, cyclic fatigue; NaOCl; ProTaper Gold; ProTaper Universal.

    Risk of pulp damage may increase due to intrachamber temperature during the usage of prophylaxis cup without paste
    (2019) Orhan, Ekim Onur; Ertugrul, Ihsan Furkan
    Aim: The aim was to measure in vitro pulp temperature increase over physiologic temperature during usage of different prophylaxis regimes at two different application pressures.Material and Methods: The aim was to measure in vitro pulp temperature increase over physiologic temperature during usage of different prophylaxis regimes at two different application pressures.Results: The aim was to measure in vitro pulp temperature increase over physiologic temperature during usage of different prophylaxis regimes at two different application pressures. Conclusion: Within the limitations of this in vitro study following conclusion can be drawn: Prophylaxis cups without paste generated the highest intrachamber temperature thus, the risk of pulp damage might be increased during its usage. Naturel-bristled prophy brushes generated the lowest intrachamber temperature. Vigorous application pressure increased the intrachamber temperature.
