Representative images of scores under stereomicroscope in ×16 magnification (a, c, e, g) and scanning electron microscope in ×500 magnification (b, d, f, h). (a, b) Score 0: root canal third free of precipitate and with wide-open dentinal tubules. (c, d) Score 1: precipitate in less than half of the root canal third—arrows indicate the presence of the precipitate on the root dentin. (e, f) Score 2: precipitate covering more than half of the root canal third. (g, h) Score 3: root canal third completely covered by the precipitate. : indicates the presence of the precipitate.
