Objective: The purpose of the present study is to evaluate the use of the EDTA root canal conditioner for root canal treatment, and what sort of effect can be applied to the cutting stress. Materials and Method: Seven groups according to each conditioner.
Group 1: Purified water
Group 2: Glyde (Dentsply Sirona)
Group 3: RC-Prep (Premier Dental)
Group 4 to 7: EDTA test product with varying viscosity
Attach the Protaper Next (X1 and X2) or Endo Wave (#20 and #25) to the Dentaport (J. MORITA ) and perform the operation on each model. Experiment: Measured motor current corresponding to cutting stress during the root canal preparation. Determined the working length with #10 K-file, made a glide path, cleaned and dried the canal, and then performed canal preparation with each conditioner. Measured the motor current by data logger at the apex position, as well as positions -5, -3, and -1 mm from the apex. Statistical analysis was carried out using the multiple comparison: the way of non-repeated measures ANOVA and Bonferroni’s method. Results: Regardless of which root canal conditioner was used, the motor current at the apex position and position -1 mm from the apex was increased, which means cutting stress tended to be raised. Conclusion: When using EDTA root canal conditioner while performing the root canal preparation, it is expected to be effective for removing the smear layer as well as reducing the cutting stress in a strongly curved part of the canal. Furthermore, the results showed that the effectiveness was almost evenly applied both inside and outside of the canal.
I specialize in endodontic therapy at university and are conducting concentration studies of EDTA. In AAE 17, demineralization of root canal dentin was presented using a hardness test.
