Judul : Pengaruh Obat Kumur Minyak Nilam 30% Terhadap Kekasaran Resin
Akrilik Heat Cured Kedokteran Gigi
Gigi tiruan lepasan banyak digunakan oleh masyarakat dengan kehilangan gigi untuk menggantikan gigi dan jaringan rongga mulut yang hilang. Basis gigi tiruan biasanya dibuat dari resin akrilik heat cured, dengan salah satu sifat pentingnya adalah kekasaran permukaan. Faktor-faktor seperti porositas resin, derajat keasaman rongga mulut, teknik pemolesan dan sifat absorbansi resin mempengaruhi kekasaran permukaan. Obat kumur berfungsi sebagai disinfektan gigi tiruan, dan obat kumur berbahan herbal dianggap memiliki efek samping lebih sedikit dibandingkan obat kumur kimia. Tujuan penelitian ini untuk mengetahui pengaruh obat kumur minyak nilam 30% terhadap kekasaran resin akrilik heat cured, serta efek durasi perendaman selama 24, 48, dan 96 jam. Metode penelitian ini adalah eksperimental laboratoris menggunakan desain postes-only control group. Spesimen yang digunakan sebanyak 25 spesimen resin akrilik heat cured berukuran 25 x 25 x 2 mm diuji. Sampel dibagi menjadi tiga kelompok perlakuan dengan perendaman obat kumur minyak nilam 30% selama 24, 48, dan 96 jam, serta dua kelompok kontrol (positif dengan chlorhexidine dan negatif dengan akuades). Analisis data dilakukan menggunakan uji Kruskal-Wallis. Hasil nilai uji Kruskal-Wallis menunjukkan p = 0,253 (p > 0,05), yang berarti tidak ada perbedaan signifikan pada kekasaran permukaan resin akrilik heat cured. Kesimpulan penelitian ini obat kumur minyak nilam 30% tidak mempengaruhi kekasaran resin akrilik heat cured, tetapi terjadi sedikit peningkatan kekasaran melebihi batas ideal (≤ 0,2 μm) pada kelompok 24 jam (0,265 μm), 48 jam (0,273 μm), dan 96 jam (0,284 μm).

Kata Kunci: Resin akrilik heat cured, kekasaran permukaan, basis gigi tiruan, obat kumur minyak nilam.
 

ABSTRACT Name : Azzahra De Yose NIM : 2113101010007 Study Program: Dental Education Faculty : Dentistry Title : Effect of 30% Patchouli Oil Mouthwash on the Roughness of Heat Cured Acrylic Resin In Dentistry Removable dentures are widely used by people with tooth loss to replace missing teeth and oral cavity tissues. The denture base is usually made of heat-cured acrylic resin, with one of the important properties being surface roughness. Factors such as resin porosity, oral acidity, polishing techniques and resin absorption properties affect surface roughness. Mouthwash functions as a denture disinfectant, and herbal mouthwash is considered to have fewer side effects than chemical mouthwash. The purpose of this study was to determine the effect of 30% patchouli oil mouthwash on the roughness of heat-cured acrylic resin, as well as the effect of immersion duration for 24, 48, and 96 hours. This research method was an experimental laboratory using a post-test-only control group design. The specimens used were 25 heat-cured acrylic resin specimens measuring 25 x 25 x 2 mm tested. The samples were divided into three treatment groups with 30% patchouli oil mouthwash immersion for 24, 48, and 96 hours, and two control groups (positive with chlorhexidine and negative with aquadest). Data analysis was performed using the Kruskal-Wallis test. The results of the Kruskal-Wallis test showed p = 0.253 (p > 0.05), which means there was no significant difference in the surface roughness of heat cured acrylic resin. The conclusion of this study is that 30% patchouli oil mouthwash does not affect the roughness of heat cured acrylic resin, but there is a slight increase in roughness exceeding the ideal limit (≤ 0.2 μm) in the 24-hour group (0.265 μm), 48 hours (0.273 μm), and 96 jam (0.284 μm).
