“…By incorporating methacrylate 2-tert-butylaminoethyl (TBAEMA) in acrylic resin, Paleari, et al 21 (2012) noted that the addition of 1% is sufficient to cause significant changes in fexural strength of the resin and justifes this change by incomplete polymerization of the same and permanence of residual monomer.…”

The adhesion of biofilm on dental prostheses is a prerequisite for the occurrence of oral diseases.ObjectiveTo assess the antimicrobial activity and the mechanical properties of an acrylic resin embedded with nanostructured silver vanadate (β-AgVO3).Material and MethodsThe minimum inhibitory concentration (MIC) of β-AgVO3 was studied in relation to the species Staphylococcus aureus ATCC 25923, Streptococcus mutans ATCC 25175, Pseudomonas aeruginosa ATCC 27853, and Candida albicans ATCC 10231. The halo zone of inhibition method was performed in triplicate to determine the inhibitory effect of the modified self-curing acrylic resin Dencor Lay - Clássico®. The surface hardness and compressive strength were examined. The specimens were prepared according to the percentage of β-AgVO3 (0%-control, 0.5%, 1%, 2.5%, 5%, and 10%), with a sample size of 9x2 mm for surface hardness and antimicrobial activity tests, and 8x4 mm for the compression test. The values of the microbiologic analysis were compared and evaluated using the Kruskal-Wallis test (α=0.05); the mechanical analysis used the Shapiro-Wilk's tests, Levene's test, ANOVA (one-way), and Tukey's test (α=0.05).ResultsThe addition of 10% β-AgVO3 promoted antimicrobial activity against all strains. The antimicrobial effect was observed at a minimum concentration of 1% for P. aeruginosa, 2.5% for S. aureus, 5% for C. albicans, and 10% for S. mutans. Surface hardness and compressive strength increased significantly with the addition of 0.5% β-AgVO3 (p<0.05). Higher rates of the nanomaterial did not alter the mechanical properties of the resin in comparison with the control group (p>0.05).ConclusionsThe incorporation of β-AgVO3 has the potential to promote antimicrobial activity in the acrylic resin. At reduced rates, it improves the mechanical properties, and, at higher rates, it does not promote changes in the control.

“…11 The polymer provides the advantage of low toxicity and is documented as causing no bacterial resistance. 8,11,12 In a previous report, PTBAEMA was successfully incorporated into polyethylene or stainless steel surfaces. 11,13 In addition, the polymer has also exhibited highly antimicrobial properties against Escherichia coli and S. aureus 11,13 and S. mutans in denture base resin.…”

“…2,3 Several studies have investigated the addition of antimicrobial agents into denture material to reduce or to avoid microorganism development on the surface of the prostheses material. [4][5][6][7][8] Others have added antimicrobial agents to tissue conditioners. 9,10 Poly (2 tert-butylaminoethyl) methacrylate (PTBAEMA) is a polycationic polymer that acts as a substi tute for low molecular weight biocides.…”

“…Marra et al 7 also observed antimicrobial properties against S. mutans and S. aureus when incorporating PTBAEMA in denture base resin, with no activity against C. albicans. Paleari et al 8 found the presence of amino groups when TBAEMA was incorporated into the denture base resin. The literature confirms that polymers func tionalized with the association between pendent amino groups and high antimicrobial activities.…”

Background: The characteristics of tissue conditioners support microorganism development that can threaten the health of the dentures user.Purpose: The object of this study was to evaluate the effect on antimicrobial activity, roughness and wettability surface of a tissue conditioners material combined with the antimicrobial polymer poly (2-tert-butilaminoethyl) methacrylate (PTBAEMA). Materials and methods:Specimens of tissue conditioner (Coe Soft ® ) were divided into three groups, according to the concen tration of PTBAEMA incorporated (0, 10 and 25%). Antimicrobial activity was assessed by adherence assay of one of the microorganisms, Staphylococcus aureus, Streptococcus mutans and Candida albicans. Roughness measurements were made using a Mitutoyo SJ-400, and the mean arithmetic roughness values (Ra) obtained were used for the comparisons. The wettability properties were determined by contact angle measurements. Results:The group containing 25% of PTBAEMA inhibited totally the S. aureus and S. mutans biofilm formation. A significant reduc tion in the S. aureus (Kruskal-Wallis, p = 0,001) and S. mutans (Kruscal-Wallis, p = 0,001) count for 10% PTBAEMA group compared with respective control group. No significant difference was found for C. albicans among PTBAEMA groups and control group (ANOVA, p > 0,05). Incorporating 10 and 25% PTBAEMA increased surface roughness and decreased contact angles (ANOVA and Tukey's post hoc tests, α = 5%). Conclusion:Incorporating 10% PTBAEMA into tissue conditioner increases wettability and roughness of tissue conditioner surface; and decreases the adhesion of S. mutans and S. aureus on material surface, but did not exhibit antimicrobial effect against C. albicans. Significance:The PTBAEMA incorporated into tissue conditioner could prevent biofilm formation on elderly patient.

Aim:The aim of this study was to evaluate the antifungal activity of heat-activated denture base resins modified with different concentrations of methacrylic acid (MAA). Materials and methods:Methyl methacrylate (MMA) monomer of heat-activated resins was modified with different concentrations of MAA (0, 15, 20, and 25%) for the preparation of specimens to evaluate antifungal activity of heat-activated resins. Prepared specimens were stored in distilled water at 37°C for 1 day and 1 week before the evaluation of microbial adhesion. Microbial adhesion of Candida albicans cells to acrylic samples was examined under light microscopy after Gram staining of all the acrylic samples. Data were subjected to one-way analysis of variance followed by post-hoc Tukey's honest significant difference test. A value of p < 0.05 was considered to be statistically significant.Results: Addition of MAA to the MMA monomer was found to significantly reduce the adhesion of C. albicans for all the groups. Reduction of C. albicans cell adherence was found significant for all three groups (I, II, and III) as compared to control, both at 1 day (p < 0.001) and 1 week (p < 0.001) after storage in distilled water. Conclusion:Addition of MAA to conventional denture base formulations reduced the adhesion of C. albicans. This method of incorporating antifungal property to denture base resins can effectively be used to reduce denture stomatitis in elderly and immunocompromised patients.
