| dc.description.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. | en_US |
