Influence of Concentration and Agitation of Sodium Hypochlorite and Peracetic Acid Solutions on Tissue Dissolution

ABSTRACT Aim and objective To evaluated the tissue dissolution of sodium hypochlorite (NaOCl) and peracetic acid (PA) solutions at different concentrations, with or without ultrasonic agitation. Materials and methods The following solutions were analyzed: 2.5% NaOCl, 0.5, 1 and 2% PA, 1% PA associated with 6.5% hydrogen peroxide (HP) and saline. Fragments of bovine pulp tissue with 25 ± 2g mg were immersed into test tubes containing 4 mL of the solutions for 10 minutes. In the groups with agitation, pulp tissues were submitted to 2 cycles of 1 minute of ultrasonic agitation. The specimens were weighed after the removal from the solutions. The percentage of mass loss was calculated according to the difference of mass before and after exposure to solutions. Data were submitted to ANOVA and Tukey tests (p . 0.05). Results A total of 2.5% NaOCl with or without agitation showed the higher tissue dissolution (between 64.5 and 67% of mass reduction) (p < 0.005). By comparing the PA solutions, the concentrations of 1 and 2% with or without agitation and the concentration of 0.5% with agitation showed similar dissolution activity (between 35.4 and 44% of mass reduction). The use of the ultrasonic agitation promoted an increase of the dissolution ability only for 0.5% PA. Conclusion Peracetic acid solution has pulp tissue dissolution. However, this ability is lower than 2.5% NaOCl solution. Clinical significance The sodium hypochlorite solution shows higher ability to dissolve tissue than PA.

The Difference

The impression materials that most commonly used in dentistry was alginate. Factors that must be considered was the controlled of infection transmission from alginate, it was important to do disinfection using a disinfectant solution. Alginate had imbibition properties, so that disinfection by spraying technique allowed the expansion of alginate affecting the dimensional stability of impressions. The purpose of this research was to determine the difference between the dimensional stability of alginate impression were sprayed with a solution of sodium hypochlorite 0,5% and Dettol® 5%. The method used was an experimental laboratory with post test only control group design. 27 samples were divided into 3 groups: spraying with 0.5% sodium hypochlorite solution, spraying with 5% Dettol® solution, and spraying with aquades as a controlled. Alginate impressions were sprayed with 0,5% sodium hypochlorite solution, Dettol® 5%, and aquades then filled with gypsum, and then measured dimensional stability by using micrometer screw. Data were analyzed with the Kruskal-Wallis test. The results showed that differences between the dimensional stability of alginate impressions were sprayed with a solution of sodium hypochlorite 0.5% and 5% Dettol® was not significant (p> 0,05). The conclusion of this research was there was no significant difference between the alginate impressions were sprayed with a solution of sodium hypochlorite 0,5% and Dettol® 5% to dimensional stability.

When eggs were disinfected by dipping for 14 min in sodium hypochlorite solution at 32°C before incubation, subsequent sterilization of the shells on the 19th day of incubation with mercuric chloride significantly reduced hatchability below that obtained when eggs were not so treated. Sterilization with peracetic acid did not significantly affect hatchability whether the eggs were decontaminated or not. The substitution of water for sodium hypochlorite solution did not alter the effect of the sterilizing agents on hatchability.

Objective: The aim of this study was to evaluate the effect of 0.5% peracetic acid solution and 2.5% sodium hypochlorite solution on smear layer removal of root canal walls after rotary instrumentation. Material and methods: Sixty single-rooted human teeth with standardized length had their canals instrumented by three rotary systems (Biorace, MTwo and Endowave), varying the irrigation solution, as follows (n=10): G1- Biorace System + 0.5% peracetic acid solution; G2- Biorace System + 2.5% sodium hypochlorite solution; G3- MTwo System + 0.5% peracetic acid solution; G4- MTwo System + 2.5% sodium hypochlorite solution; G5- Endowave System + 0.5% peracetic acid solution; G6- Endowave System + 2.5% sodium hypochlorite solution. After instrumentation, the roots were cleaved and the dentin walls were evaluated by SEM at x500 and x2000 magnification for assessing the cleaning of the root canals at the cervical, middle and apical thirds. The analyzed area was quantified according to the total number of tubules present and the percentage of open tubules at each region. Data were submitted to statistical analysis by ANOVA and Tukey tests, at the significance level of 5%. Results: There were no statistical significant differences among the experimental groups. In all groups the smear layer removal at cervical and medium thirds was higher than that of apical third. Conclusion: It was concluded that the cleaning obtained at the apical third was lower in all groups studiedand neither the instrumentation technique nor the irrigating solution was able to promote total smear layer removal from root canal walls.

ABSTRACT Objective: To evaluate the microhardness of specimens of acrylic resins VipiCril® (thermally polymerized resin) and Bosworth New Truliner® (self-polymerized resin), before and after immersion in solutions of 0.12% chlorhexidine digluconate, 1% sodium hypochlorite, Corega Tabs® and water (control), testing the null hypothesis that the mouthwashes and chemicals used to disinfect complete dentures do not interfere with the superficial microhardness, and can therefore be used as adjuncts to oral hygiene of edentulous patients. Methods: Sixty specimens of resin VipiCril®(thermally polymerized resin) and 60 specimens of resin Bosworth New Truliner® (self-polymerized resin) measuring 16 mm of diameter and 6 mm of height were prepared, which were randomly divided into four groups of 15 specimens each, undergoing Knoop hardness tests (KHN) both before and after cycles of immersion in solutions of 0.12% chlorhexidine digluconate, 1% sodium hypochlorite, Corega Tabs® and water (control). Results: The specimens of resins VipiCril and Bosworth immersed in solutions of 0.12% chlorhexidine, Corega Tabs® and water showed decreased microhardness. Conclusion: The 1% sodium hypochlorite solution caused least damage to the denture structure, not leading to decrease of the superficial microhardness.
