INTRIAGO MORALES, Ruth Viviana et al. Comparison of three irrigation techniques in the removal of calcium hydroxide. Rev. Estomatol. Herediana [online]. 2018, vol.28, n.4, pp.245-251. ISSN 1019-4355. http://dx.doi.org/https://doi.org/10.20453/reh.v28i4.3426.
Objectives: To compare efficacy of three irrigation protocols in the removal of calcium hydroxide (Ca(OH)2). Materials and Methods: Through an in vitro comparative study design, 106 root canals of bovine incisors were instrumented up to a file of diameter 60, the roots were fractioned into two halves following the major axis of the tooth and a standardized groove was created 2mm from the apical foramen that was filled with a paste of calcium hydroxide, then the halves were reassembled, incubated for 7 days and the irrigation protocols were carried out: passive ultrasonic (PUI), sonic with Endo Activator (EA) and manual dynamic activation (MDA), where 5% sodium hypochlorite (NaOCl) was used as irrigant. A negative and positive control was used. With a stereomicroscope the amount of residue was observed, the images were examined and assigned a score according to the van der Sluis scale, finally the data were analyzed with the statistical test of Chi-square. Results: The percentages of efficacy for PUI, EA and MDA irrigation protocols were 87.5%; 46.9% and 28.1% respectively, the PUI technique was superior to EA and MDA and obtained statistically significant differences (p <0.001). Conclusions: PUI was the most effective method in the removal of Ca(OH)2 from the simulated grooves in the root canals.
