Abstract

Fructose, which is the highest concentration of substance in honey, can stimulate saliva more than sucrose, so it is considered to affect the acidity (pH) of saliva, especially postmenopausal women who generally experience a decrease in salivary pH. This study aims to determine the ratio of salivary pH of menopausal women who rinse with drinking water and rinse with 15% concentrated honey. A sample of 32 postmenopausal women between the ages of 50-60 years were divided into 2 groups, namely the control group and the treatment group. Before being treated, the initial salivary pH of the two groups was recorded. Then the control group was instructed to rinse with drinking water and the treatment group was instructed to rinse with 15% honey. Both groups rinsed at the same time for 3 minutes. Then the salivary pH of each group is measured. Data analyzed by independent t-test between the two groups, showed a significance value of 0.037 in the control group and 0.041 in the treatment group (p <0.05). Paired t-test conducted in each group produced a significance value of 0.164 for the control group and 0.07 for the treatment group (p <0.05). Gargling with honey 15% can significantly increase the salivary pH of menopausal women compared to gargling with drinking water.

Abstract

Introduction: Thermoplastic nylon is one of the alternative materials used for denture bases, in addition to acrylic resin. It offers good flexibility and aesthetics; however, its high water absorption makes it susceptible to microbial colonization. Sansevieria trifasciata is a herbal plant known for its antiseptic, antibacterial, and antifungal properties. Therefore, it has the potential to be developed as a natural denture cleanser. This study aims to determine the antifungal effect of a 40% S. trifasciata var. laurentii infusion on the growth of Candida albicans colonies on thermoplastic nylon denture base plates. Material And Methods: This in vitro experimental study used a post-test only control group design with four groups: one negative control (sterile distilled water) and three groups treated with 40% S. trifasciata infusion for 24, 48, and 72 hours. A Candida albicans suspension (1.5 × 10⁸ CFU/mL) was prepared using McFarland standard 0.5. Phytochemical screening was conducted to identify active compounds in the extract. Data were analyzed using One-Way ANOVA and LSD post hoc test (p < 0.05). Results and Discussions: Phytochemical analysis of the S. trifasciata var. laurentii extract indicated the presence of saponins, phenols, flavonoids, and alkaloids, all of which are known to exhibit antifungal activity. The descriptive analysis showed that the treatment group with 72-hour immersion had the lowest average colony count of C. albicans. Statistical analysis using One-Way ANOVA showed a significant difference among the groups (p = 0.001). LSD post hoc analysis revealed that all treatment groups differed significantly from the control group (p < 0.05). These results indicate that prolonged immersion in S. trifasciata var. laurentii infusion enhances its antifungal efficacy. The observed antifungal activity is likely related to the disruption of fungal cell membranes by the active compounds present in the extract. Conclusion: The 40% S. trifasciata var. laurentii infusion is effective in inhibiting the growth of C. albicans on thermoplastic nylon denture base plates. The most significant antifungal effect was observed with a 72-hour immersion duration.

Abstract

The global incidence of oral lesions ranges from 5% to 66%, with an average of 20%. To date, no scientific research has investigated the effects of Catharanthus roseus L. (tapak dara) leaf extract on the expression of proinflammatory cytokines in oral lesion healing. This study aimed to evaluate the effectiveness of tapak dara leaf extract gel in reducing the expression of the proinflammatory cytokines TNF-α and IL-1β during oral lesion healing. A total of 30 mice (Mus musculus) were divided into five groups: four treatment groups and one control group, each housed separately. The gel formulation was prepared by mixing diluted extract solutions (5%, 10%, and 20%) into a 2% CMC-Na solution, heated and stirred for 10 minutes, and then cooled to achieve a gel consistency. Phytochemical screening was performed to qualitatively identify flavonoids, tannins, saponins, phenolics, alkaloids, steroids, and terpenoids. Expression levels of TNF-α and IL-1β were measured using an ELISA kit. ANOVA results showed that tapak dara leaf extract gel at 5%, 10%, and 20% significantly reduced TNF-α and IL-1β expression (p = 0.001). Tukey’s post hoc test indicated that the positive control (K+) group had the lowest expression of both TNF-α and IL-1β compared to other groups (p = 0.001). In conclusion, tapak dara leaf extract gel effectively reduces TNF-α and IL-1β expression, supporting its potential role in the healing process of oral lesions.

Abstract

Introduction: Surface roughness is an important property of denture base materials because it affects hygiene, comfort, and durability. Rough surfaces can retain debris and microorganisms, increasing the risk of halitosis and mucosal irritation. Tuak aren (Arenga pinnata palm wine), a traditional fermented beverage, contains alcohol and has an acidic pH that may alter denture base materials. This study evaluated the effect of tuak aren on the surface roughness of acrylic and thermoplastic nylon denture bases. Materials and Methods: Four groups were studied: acrylic plates (A1) and thermoplastic nylon plates (A2) immersed in distilled water as controls, and acrylic plates (B1) and thermoplastic nylon plates (B2) immersed in tuak aren as treatments. After 11 days of immersion, surface morphology was examined using scanning electron microscopy (SEM), and surface roughness was measured using a profilometer. Results: Descriptive analysis showed that A1 had the lowest surface roughness, while B2 had the highest. One-way ANOVA demonstrated significant differences among groups. LSD post hoc analysis revealed significant differences between B2 and groups A1, A2, and B1. SEM observations at 500× magnification showed microscopic surface changes after immersion in tuak aren. Profilometer measurements were consistent with SEM findings. Conclusion: Exposure to tuak aren increased the surface roughness of denture base materials, with the greatest effect observed in thermoplastic nylon plates.
