Acrylic resin dentures are a type of denture that is often used. At present the use of disinfectants to clean dentures from microorganisms, such as sodium hypochlorite and green betle leaves. Sodium hypochlorite contains chlorine, and green betle leaf extract contains tannins that containable to provide color changes in artificial teeth. The purpose of this study was to study the change in color on the hot polymerization acrylic plate after soaking with sodium hypochlorite solution and green betle leaf extract (Piper betle Linn). This study was a pre-post test control group design, the sample was heat-cured resin acrylic base plate and divided into 3 treatment groups: a group immersed in sodium hypochlorite, extract of green betel leaf and control group with aquades. The discoloration measurement was using Spectrophotometer. The sample was immersed for 15 days. Data were analyzed by paired T-test, followed by One way Anova and LSD. The results showed that there were significant color changes in the 2 treatment groups, while the control group was not significant. The mean of discoloration after immersion with Sodium Hypochlorite was 0.668 + 0.018, green betle leaf extract 30% was 0.625 + 0.024, and aquades was 0.534 + 0.0224. Color changes on heat-cured resin acrylic base plate occur by the presence of chlorine in sodium hypochlorite and tannin contained in the green betel leaf extract. This research concluded that immersion of heat-cured resin acrylic plate in sodium hypochlorite solution and 30% betle leaf extract may cause discoloration.

Gigi tiruan diperlukan dalam pemenuhan kesehatan pada umumnya serta kesehatan gigi dan mulut khususnya terutama untuk mempertahankan fungsi kunyah.Tujuan penelitian adalah ingin mengetahui persentase jumlah masyarakat Desa Petang yang menggunakan gigi tiruan untuk menggantikan gigi alami yang telah dicabut.

Accumulation of plaque and food scraps on an acrylic resin base will increase bacterial colonies and C. albicans which will cause denture stomatitis. Maintenance of denture hygiene using mechanical, chemical and combination of two methods. Basil leaf extract contain essential oils which are important in fight against resistant C. albicans biofilms. The purpose of this study was to determine the comparison of C. albicans colonies after cleaning various denture cleaning methods. The method of this study is used an experimental method, the study design is posttest only with control group design. Sample size of heat-cured acrylic resin plate is 40x12x3mm. this study use Kruskall-Wallis test and Mann-Whitney test as data analysis for comparison tests between groups (non-parametric test). The results showed that there were significant differences between the various cleansing methods used in reducing C. albicans colonies. The compotition of flavonoids basil leaf extract is anti-microbial which can prevent the entry of fungi that harm the body.
