Evaluation of activated irrigation techniques for the removal of calcium hydroxide from simulated internal root resorption cavities: an in vitro comparative study
Abstract Background This study aimed to compare the calcium hydroxide [Ca(OH)₂] removal efficiency of six irrigation‑activation techniques and conventional syringe irrigation (control) from simulated internal root‑resorptive cavities in vitro. Materials and methods Seventy single-rooted human teeth were standardized to a length of 18 mm, prepared, and split longitudinally. A standardized hemispherical resorptive cavity was created in each root half; the halves were then reassembled and filled with premixed Ca(OH)₂. …
