“…It is reported that 1 mL of a healthy person's saliva sample contains about 750 million microorganisms . Thus, the disinfection of impressions after they make contact with oral tissues, saliva, and/or blood is an important step in dental practice to prevent the risk of the transfer of organisms to clinical and laboratory personnel . The hypothesis tested in this study, that significant differences exist in the properties of a hydrocolloid according to the AgVO 3 concentrations, was accepted.…”

The inoculum suspensions containing ß10 8 colonyforming units (CFU)/mL −1 of bacterial growth in the exponential phase were made by reading the optical density in a spectrophotometer (Multiskan GO; Thermo Fisher Scientific, Waltham, MA) at a 625 nm wavelength.…”

Purpose To evaluate the antimicrobial activity and physico‐mechanical properties of an irreversible hydrocolloid in which nanostructured silver vanadate decorated with silver nanoparticles (AgVO3) was added at various concentrations (0% ‐ control, 2.5%, 5%, and 10% by weight). Materials and Methods The agar diffusion method (n = 10) was used to evaluate the inhibitory effect on the following species: Streptococcus mutans, Staphyloccocus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. The gelation time, flow capacity and plastic deformation were verified (n = 10). The data were analyzed using the Kruskal‐Wallis test followed by the Dunn post‐test, or via one‐way ANOVA with multiple comparisons with a Bonferroni adjustment depending on the distribution (α = 0.05). Results All percentages of the nanomaterial were able to promote the antimicrobial activity of a hydrocolloid, with the formation of an inhibition zone (p < 0.05). In general, there was a dose‐dependent effect on antimicrobial activity: higher concentrations of the nanomaterial promoted greater action except in the cases of P. aeruginosa (p < 0.001; F = 51.74) and S. aureus (p < 0.001), where the highest inhibition was for the 2.5% group. No difference was found in the gelation time when the control was compared with the groups with AgVO3 (p > 0.05). The difference was between the 5% and 10% groups (p = 0.007), and the latter promoted an increase in time. The flow capacity of the hydrocolloid with 5% of AgVO3 was significantly lower when compared with the control (p = 0.034). The AgVO3 influenced the plastic deformation (p < 0.001) in such a way that concentrations of 5% (p = 0.010) and 10% (p < 0.001) promoted an increase in this property when compared with the control. Conclusions AgVO3 can be incorporated into an irreversible hydrocolloid as an antimicrobial agent without promoting adverse effects on physical‐mechanical properties when used in concentrations of 2.5%.

This in-vitro study investigated the effect of immersion and spray atomization technique of disinfection using 0.5% of sodium hypochlorite solution on compression resistance of polyvinyl siloxane and polyether interocclusal recording materials. This study comprised of a total of 60 samples, wherein 30 samples each of polyvinyl siloxane and polyether underwent compression resistance. These 30 samples of each were again divided into 3 subgroups comprising of 10 specimens each-a control group, a group subjected to spray atomization disinfection technique for 10 mins and a group subjected to immersion technique for 10 mins following which they were subjected to compression resistance in a universal testing machine. One-way ANOVA and Post-Hoc Tukeys test were used for statistical analysis. Results showed that Polyvinylsiloxane interocclusal recording material showed better resistance to compression than polyether interocclusal recording material and Immersion technique of disinfection was better for polyvinylsiloxane and spray atomization technique of disinfection for polyether. Hence it could be concluded that Polyvinylsiloxane material can be used as an interocclusal recording material because of its greater resistance to compression and can be subjected to immersion technique of disinfection.

Aim:The aim of this in vitro study was to comparatively evaluate the effect of chemical disinfectants on the surface detail reproduction, dimensional stability and surface texture of polyvinyl siloxane (PVS) impressions.Materials and Methods:The impressions were then divided into five groups (fifteen samples per group) and subjected to a ten minutes immersion with 2% glutaraldehyde (Group I), 1% sodium hypochlorite (Group II), freshly prepared electrolyzed oxidizing water (EOW) with different pH values - acidic (Group III), alkali (Group IV) and neutral (Group V). The samples were examined pre and post-immersion under visual observation for surface detail reproduction, travelling microscope for measurement of dimensional stability and surface profilometer (3D) for evaluation of surface texture. A standardized master die was fabricated and seventy-five PVS test samples were made. The samples were subjected to immersion disinfection and studied for surface detail reproduction, dimensional stability and surface texture. Post-hoc test, paired t test and ANOVA were used to analyze dimensional stability statistically both within and between the test groups.Results:The surface detail reproduction was satisfactory with both pre and post-immersion test samples. A statistically significant dimensional change was observed post-immersion in Groups II, III and V test samples and a statistically insignificant dimensional change was observed in Groups I and IV test samples. There was a negligible change in surface texture post-immersion in Groups I, III, IV and V test samples with a slight increase in surface roughness post-immersion in Group II samples.Conclusion:In this study, all the test disinfectants produced satisfactory surface detail reproduction on Polyvinyl siloxane impressions. 2% glutaraldehyde and electrolyzed oxidizing water (alkali) have resulted in statistically insignificant dimensional change, while 1% sodium hypochlorite, electrolyzed oxidizing water (acidic) and electrolyzed oxidizing water (neutral) have resulted in statistically significant dimensional changes. All the test disinfectants except 1% sodium hypochlorite showed a reduction in surface roughness (Ra) values.
