Ex vivo analysis of root canal cleaning using Endo-PTC associated to NaOCl and different irrigant solutions

Abstract

The aim of this study was to assess qualitatively, by means of SEM images, the cleaning of the dentin walls of root canals after chemical-surgical preparation using Endo-PTC cream with 0.5% and 1% sodium hypochlorite and different final irrigating solutions. Seventy-two single-rooted human teeth were divided into eight groups and prepared using Endo-PTC cream with sodium hypochlorite (NaOCl) at different concentrations, and irrigated with NaOCl at different concentrations. Final irrigation was performed with either EDTA-T or EDTA-C. The best results were obtained with Group 1, followed by Groups 5, 2, 7, 8, 3, 6 and 4. We can conclude that the use of 0.5% NaOCl during instrumentation and final flush of the root canals was more efficient in cleaning than was 1% sodium hypochlorite. EDTA-T was more efficient in removing smear layer than EDTA-C, and the cervical third presented better cleaning of the root canal walls than did the middle third, which showed cleaner dentin walls than the apical third.

Development of Intracanal Formulation Containing Silver Nanoparticles

“…In this way, an adequate fluidity is necessary to facilitate penetration and draining of the radicular canal (24). Yamazaki et al (25) studied dentin permeability and efficiency of Endo-PTC (which is utilized as a lubricant in endodontic instrumentation) in semi-solid pharmaceutical forms with different excipients as hydroxyethylcellulose or carbomer polymeric gels and associations of polyethylene glycol and surfactants. The results did not show differences between the evaluated preparations in terms of penetration capacity into dentin tubules or efficiency.…”

Evaluation of cleaning capacity and instrumentation time of manual, hybrid and rotary instrumentation techniques in primary molars

“…The association of Endo‐PTC and 0.5% sodium hypochlorite has been found to promote satisfactory cleaning of root canals compared with other solutions (Yamazaki et al. 2010).…”

“…The association of Endo-PTC and 0.5% sodium hypochlorite has been found to promote satisfactory cleaning of root canals compared with other solutions (Yamazaki et al 2010). Pinheiro et al (2009) clinically that manual instrumentation using Endo-PTC and 0.5% sodium hypochlorite resulted in a reduction of 82.59% of viable bacteria in primary molars with necrotic pulps.…”

Effect of endodontic irrigating solutions on the adhesive bond strength to dentin

“…In the teeth where endodontic treatment is indicated, the combined use of endodontic irrigating solutions that clean, disinfect and shape the root canal system for posterior filling are necessary and essential for the therapy success (5,6).…”
