This study used a mechanical test to evaluate the flexibility of instruments from the K3 (conicity 0.04) and the ProTaper Universal systems when they were new and after 5 uses in simulated canals. Five sets of instruments of each system were tested: K3 (15, 20, 25, 30, 35, 40 and 45) and ProTaper Universal (S1, S2, F1, F2, F3, F4 and F5).

- This study aimed to examine the impact of chlorhexidine (CHX) digluconate at different concentrations (0.2% and 2%) on the durability of dentin bonding using two adhesive systems: etch-and-rinse and self-etch.
- The research involved testing on 24 human third molars where the bonding systems were applied, followed by microtensile tests after immediate use and 6 months of simulated stress.
- Results indicated that the 2% CHX concentration helped maintain bond strength significantly better over time compared to the lower concentration, especially with the etch-and-rinse adhesive, while the self-etch adhesive showed some limitations with 0.2% CHX.
