Abstract

MORALES-GUEVARA, Aurealuz. In vitro Dentinary Penetration of Sodium Hypochlorite at Different Concentrations with the Conventional and Ultrasonic Passive Irrigation Techniques. Int. J. Odontostomat. [online]. 2017, vol.11, n.3, pp.305-309. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2017000300305.

The objective of the present study was to compare in vitro dentin penetration between 5 % and 2.5 % sodium hypochlorite (NaClO) concentrations using conventional irrigation and passive ultrasonic irrigation techniques. This was a cross-sectional, prospective and experimental study. It was worked with 40 root segments (specimen) of 5 mm length, divided into 4 groups. All specimens were immersed in crystal violet for 24 hours. The biomechanical preparation was performed with Pro Taper rotary system. The first group was irrigated with 2.5 % NaClO with conventional irrigation, the second group with 2.5 % NaClO with conventional irrigation plus ulrasonic passive irrigation for 30 seconds, the third group with 5 % NaClO with conventional irrigation and the fourth with 5 % NaClO with conventional irrigation plus ultrasonic passive irrigation for 30 seconds. At the end of the preparation, all specimens had a distal mesio cut. The depth of NaClO penetration was determined by bleaching of the stain and measured with a light microscope at a magnification of 40 X. The statistical test used was ANOVA with a significance level of 5 %. The 5 % NaClO with passive ultrasonic irrigation showed the highest dentin penetration in vitro.

Keywords : dentin; sodium hypochlorite; therapeutic irrigation.
