The Analysis of the Differences between the Influence of Herbal Mouthwashes and the Chlorhexidine Mouthwash on the Physical Characteristics of Orthodontic Acrylic Resin

Abstract

The present study, intended to compare the effects of immersion in herbal mouthwashes and the Chlorhexidine mouthwash on orthodontic acrylic resin, specifically with regard to alterations in its hardness, roughness and color. Seventy-two specimens of Orthodontic self-cured acrylic resin were used for the experiments. After preparation, specimens were placed in three types of mouthwash including Chlorhexidine 0.2 % (CHX), Persica and Matrica. The changes in microhardness (ΔKNH), Surface roughness (ΔRa) and color (ΔE) were evaluated prior to and following the immersion in mouthwashes. In order to analyze the data, we made use of SPSS version 22. One-Way ANOVA test was used to find the differences between groups. The Tukey test was conducted in the final stage. It was revealed that acrylic resins had lower microhardness when 12 hours after immersion had taken place. There were significant differences after 12h, 24h and 7 days between the groups in the softening of acrylic resins. The reduction in microhardness of acrylic resin with herbal mouthwashes in the three-time intervals was higher than CHX. With regard to increasing surface roughness, the disparity between herbal mouthwashes was insignificant. However herbal mouthwashes significantly increased the value of roughness more than CHX. Changes in color were significantly higher in all mouthwashes. Herbal mouthwashes caused more color variation than CHX. The color, roughness and hardness of acrylic resin undergo changes as a result of being immersed in the mouthwashes. However, the effect of herbal mouthwashes was more than that of CHX.

Impact of different chemical denture cleansers on the properties of digitally fabricated denture base resin materials

“…Possibly due to water absorption by the acrylic resin causing subsequent leach out of plasticizers and breakage of resin material. 34 These results agreed with the findings of some authors 5,34,26 who stated that CDCs increase the surface roughness of DBM resins by hygroscopic expansion, polymer degradation, immersion in warm solutions, as well as by the increase of pH of immersing solution.…”

“…Previously, it was found that ethanol and water act as plasticizers that soften the DBM through penetration into the interpolymeric spaces causing separation of the polymer chains and plastic deformation. 26 These findings are in accordance with Degirmenci et al 7 who reported that Corega and CHX produced notable changes in the surface roughness of resin DBM compared to DW solution.…”

“…The Corega solution was prepared by dissolving one tablet (Effervescent denture cleaner, Stafford-Mille Limited Co., Waterford, Ireland) in 200 mL of warm water (40 • C) according to the manufacturer's recommendations, and the specimens were soaked for 3 min/day. 5,6 Two hundred and fifty milliliters of CHX immersion solution (0.2%) (The Arab Drug Co., Pharmaceutical and Chemical Industries, Egypt) was used to soak the specimens 7,14,26 for 15 min/day.…”

The effect of photodynamic therapy in controlling the oral biofilm: A comprehensive overview

“…A combination of inadequate or excessive antibiotic use and difficulties in accessing topical agents with efficacy against biofilms have led to an increase in antibiotic resistance. Dental biofilms can be controlled with chlorhexidine (CHX), a cationic broad-spectrum antibacterial [82]. An important component of this effectiveness is substantivity, a property that binds the molecule to tissues and exerts antibacterial activity for over 12 h after application.…”

“…Learning details of materials are very important for customizing them for specific applications, and such issues are currently the targets of several studies using various aspects and methods [37][38][39][40]. Among such efforts, the herbs have been found very interesting to be explored in addition to the exploration of other types of drugs and biomaterials modifications [41][42][43]. To this aim, the current review work was systematically focused on effects of herbal sativa on hypertension to provide more insights into the issues of metabolic syndrome.…”
