OBJECTIVE To evaluate the effect of diode laser irradiation on crystallographic and morphologic characteristics of root canal walls after final irrigation with either 17% EDTA or BioPure MTAD. METHOD AND MATERIALS Root canals in 60 single-rooted teeth were instrumented using a rotary Ni-Ti system. The teeth were randomly divided into three groups (n = 20)(More)
A computational study at the level of density functional theory (DFT) was carried out to investigate C-H...O=C and N-H...O=C hydrogen-bonding interactions (HBs) in the real crystalline cluster of thymine by O-17, N-14 and H-2 calculated nuclear quadrupole resonance (NQR) parameters. To perform the calculations, a hydrogen-bonded pentameric cluster of(More)
INTRODUCTION Solubility of root filling materials is heavily influenced by the environment they are in contact with. This study compared the solubility of ProRoot MTA in deionized water and synthetic tissue fluid. MATERIALS AND METHODS Forty specimens of prepared MTA were immersed in deionized water and synthetic tissue fluid (20 samples each). The(More)
