Pengaruh Penyikatan Basis Gigi Tiruan Resin Akrilik Polimerisasi Panas dengan Pasta Kombinasi Ekstrak Andaliman (Zanthoxylum acanthopodium DC) dan Kulit Markisa Ungu (Passiflora edulis) terhadap Sifat Fisis

Abstract

Tooth loss can be managed using heat-polymerized acrylic resin (HPAR) dentures, however this material has drawbacks such as porosity that increases surface roughness of HPAR. Alkaline peroxide is a commonly used cleanser, but long-term use may elevate roughness and cause whitening of the denture surface. Therefore, herbal-based ingredients are increasingly preferred as safer long-term alternatives, including andaliman, which contains quercetin, and purple passion fruit peel, which contains acethydrazide as antifungal. This study aimed to evaluate the effects of brushing HPAR denture base with a combination paste of andaliman (Zanthoxylum acanthopodium DC) and purple passion fruit peel (Passiflora edulis) extract on physical properties. This laboratory experimental study used 30 HPAR samples divided into five groups: alkaline peroxide, aquadest, and three extract formulations (formulation 1: 5%:10%, formulation 2: 7.5%:7.5%, formulation 3: 10%:5%). Samples underwent mechanical brushing simulation equivalent to 1, 2, 3, 4, and 5 years, followed by surface roughness and color stability testing. Data were analyzed using Two-Way ANOVA. Results showed that brushing duration and formulation type significantly affected both parameters (p<0.05), while their interaction was not significant (p>0.05). Formulation 1 exhibited the smallest color change (1.580 ± 0.759), indicating the best color stability within clinically acceptable limits (ΔE*<3.3). Formulation 3 showed a surface roughness difference of 0.095 ± 0.015 µm, still within clinically acceptable limits (<0.2 µm). Overall, formulation 1 demonstrated the most effective performance, with both surface roughness and color stability remaining clinically acceptable.
