Abstract

Latar Belakang: Resin akrilik polimerisasi panas merupakan salah satu bahan basis gigi tiruan yang paling banyak digunakan di kedokteran gigi. Resin akrilik memiliki keterbatasan seperti sifat menyerap cairan dalam jangka panjang. Pembersih seperti effervescent alkalin peroksida efektif untuk membersihkan gigi tiruan tetapi dapat meningkatkan kekasaran permukaan sehingga dibutuhkan alternatif pembersih lain seperti granul effervescent ekstrak kulit putih semangka merah. Metode: Jenis penelitian yang digunakan adalah experimental laboratoris. Sampel penelitian adalah plat resin akrilik polimerisasi panas ukuran 64 x 10 x 3,3 mm. Tiga kelompok perlakuan terdiri atas larutan aquadest, larutan effervescent alkalin peroksida, dan larutan granul effervescent ekstrak kulit putih semangka merah (n=5). Pengukuran kekasaran menggunakan Surface Roughness Tester dan hasil dianalisis menggunakan uji One Way ANOVA. Hasil: Rata-rata kekasaran permukaan resin akrilik polimerisasi panas setelah dilakukan perendaman dalam larutan aquadest, effervescent alkalin peroksida dan granul effervecsent alkalin peroksida berturut-turut adalah 0,114 ± 0,795; 0,280 ± 0,112; dan 0,118 ± 0,095. Penelitian ini menunjukkan bahwa granul effervescent ekstrak kulit putih semangka merah berpengaruh terhadap peningkatan kekasaran plat resin akrilik polimerisasi panas. Kesimpulan: Granul effervescent ekstrak kulit putih semangka merah dapat meningkatkan kekasaran permukaan dalam batas normal sehingga dapat dijadikan sebagai alternatif pembersih gigi tiruan.

Abstract

Artificial teeth elements are essential components of removable dentures. Inadequate cleaning can lead to the accumulation of microorganisms, which may cause denture stomatitis. Alkaline peroxide effervescent tablets are commonly used denture cleansers. However, prolonged use may increase the surface roughness of artificial teeth. To address this, an alternative natural-based cleanser has been formulated using red watermelon (Citrullus lanatus) rind extract in effervescent granule form. Effervescent granules of watermelon rind extract have potential as an alternative denture cleanser due to their antibacterial properties. The effervescent reaction helps mechanically remove plaque and debris while inhibiting the growth of microorganisms that cause odor and infection. This formulation is practical, natural, and economical. The study aims to evaluate the effect of immersion in effervescent granules containing watermelon rind extract on the surface roughness of artificial teeth. This was a laboratory experimental study using acrylic resin-based artificial teeth. Samples were divided into three treatment groups: aquadest, alkaline peroxide effervescent solution, and watermelon rind effervescent granule solution (n = 5). Surface roughness was measured using a Surface Roughness Tester, and data were analyzed with the Kruskal–Wallis test (p < 0.05). The mean surface roughness values after immersion in aquadest, alkaline peroxide solution, and watermelon rind effervescent granules were 0.140 ± 0.026 µm, 0.616 ± 0.213 µm, and 0.670 ± 0.041 µm, respectively. The findings demonstrate that immersion in effervescent granules containing watermelon rind extract significantly increases the surface roughness of artificial teeth. Further formulation development is recommended to optimize its potential as a natural denture cleanser.
