“…It is noteworthy that the amount of additives is of critical importance. In previous study (13) , the hardness was significantly decreased with henna concentration of 2.5% and more, while it has insignificant decrease of hardness with 1% henna. According to the results of the present study, when henna exceeded a particular percentage (2.5%), PMMA/henna composite decreased the flexural strength values dramatically.…”

“…According to the results of the present study, when henna exceeded a particular percentage (2.5%), PMMA/henna composite decreased the flexural strength values dramatically. The decrease above this amount may be attributed to the fact that the maximum saturation of the matrix formation between PMMA and henna occurred at concentrations of 2.5wt% (13,28) .…”

“…The construction of a denture base with an antimicrobial effect would be a remarkable achievement (3) . At the same time, the physical properties should not be unduly altered (13) . It seems that addition of henna to PMMA for antimicrobial activity would be beneficial but it should be performed under particular care and after evaluation of its effect on the physical properties of the acrylic resin.…”

“…The surface properties of acrylic resin can be affected by hardness, which is characteristic of the ease of finishing the material as it is resistant to in-service scratching during cleansing (12) . Therefore, study conducted to evaluate the effect of henna addition on the surface properties of PMMA and the results showed that the tested properties were adversely affected with more than 2.5% concentrations (13) .…”

Purpose: The purpose of this study was to evaluate the flexural strength of the acrylic denture base material modified with different concentrations of henna. Materials and Methods: Sixty heat polymerized acrylic resin specimens were fabricated in dimensions 65×10×2.5 mm according to ADA specifications #12. Specimens were divided according to henna concentrations into 6 groups. One control group without henna addition while the other five groups were processed by adding henna in concentrations 1%, 2.5%, 5%, 7.5% and 10% of acrylic powder. After processing, specimens were finished, polished, and stored in distilled water at 37 o C for 48±2 hours prior to testing. The three-point bending test was used to measure the flexural strength using universal testing machine. The morphology of the fractured specimens was studied under a scanning electron microscopy (SEM). The independent sample t-test was used and p≤ 0.05 was considered statistically significant. Results: The flexural strength significantly decreased with henna addition to PMMA denture base material (P<0.05), and this decrease was in proportional to henna concentrations. Conclusion: The flexural strength of acrylic denture base material negatively was affected by henna addition.

“…Other management methods, including the incorporation of antimicrobial agents within the denture base resin itself, have been suggested to limit fungal growth . Although a promising antifungal effect was seen, deterioration in mechanical properties and nonesthetic color changes of denture bases were reported . Additionally, the durability of these antimicrobial additions over time was neglected.…”

Purpose:To evaluate the effect of protective coatings on the surface roughness, contact angle, and Candida albicans (C. albicans) adhesion to polymethyl methacrylate (PMMA) denture base materials. Material and Methods: A total of 560 rectangular heat-and autopolymerized acrylic resin specimens were fabricated and divided into 5 groups (n = 14/group) according to coating agent. Uncoated specimens were used as control. Coating materials were: nano-coat, Optiglaze, nano-silica, or cyanoacrylate. Surface roughness (R a ) was evaluated using a profilometer. Contact angle measurements were performed using the sessile drop method. C. albicans adhesion was evaluated using direct culture and slide count methods. ANOVA and Tukey's post hoc tests were used for data analysis (α = 0.05). Results: Nano-coat and Optiglaze coating of heat-polymerized acrylic significantly decreased R a (p < 0.001). No significant effect was seen with nano-silica coating while R a significantly increased with cyanoacrylate (p < 0.001). For autopolymerized acrylic, nano-coat, Optiglaze, and nano-silica coatings significantly decreased R a in comparison to control group (p < 0.001) while no significant difference was seen between control and cyanoacrylate coating (p = 0.45). In comparison to control group, nano-coat, Optiglaze, and nano-silica coating for both denture base materials significantly decreased contact angle, and C. albicans adhesion (p < 0.001) while cyanoacrylate significantly increased C. albicans adhesion (p = 0.002) with no effect on contact angle for heat-(p = 1.00) and autopolymerized resins (p = 0.83). Conclusion: Coating of removable prosthesis with nano-coat, Optiglaze, or nanosilica is an effective method to reduce C. albicans adhesion.

Effect of Henna Addition on the Surface Roughness and Hardness of Polymethylmethacrylate Denture Base Material: Anin vitroStudy

Abstract: Antimicrobial denture with minimum deterioration effects on its physical properties could be achieved with henna addition to denture base material in low concentration. However, 1% henna showed the best results between the henna groups as regards roughness and hardness values.
