Abstract

Pendahuluan: Glass fiber non dental merupakan bahan yang digunakan sebagai penguat gipsum dan komponen otomotif dengan komponen yaitu Na2O dan K2O dapat meningkatkan ketahanan terhadap asam dan meningkatkan penyerapan air. Glass fiber non dental banyak tersedia di Indonesia dengan harga yang terjangkau dapat menjadi alternatif pengganti dari E-glass fiber dental yang ketersediaannya terbatas di Indonesia dan harga relatif mahal. Tujuan penelitian adalah menganalisis pengaruh jumlah glass fiber non dental pada reinforced resin akrilik terhadap perlekatan C.albicans. Metode: Jenis penelitian yaitu Eksperimen laboratorium dengan rancangan Posttest Control Group Design  yang dilakukan untuk mengetahui pengaruh jumlah glass fiber non dental pada reinforced resin akrilik terhadap perlekatan C. albicans  dengan 12 sampel yang dikelompokkan menjadi 3 kelompok yaitu glass fiber non dental 0,9 %, glass fiber non dental 1,8 %, dan tanpa fiber. Analisis statistik menggunakan uji Oneway ANOVA dengan nilai p < 0,05. Hasil:  penelitian menunjukkan bahwa glass fiber non dental 0,9 % ( hasil rata-rata: 1,10),  glass fiber non dental 1,8 % (hasil rata-rata: 1,125), dan tanpa fiber (hasil rata-rata: 1,525) memiliki efek berbeda tetapi tidak bermakna. Simpulan: Penambahan glass fiber non dental pada lempeng resin akrilik tidak berpengaruh terhadap perlekatan C. albicans.Kata kunci: Glass fiber non dental,  fiber reinforced resin akrilik, Candida albicans ABSTRACTIntroduction: Non-dental glass fiber is a material used as gypsum reinforcement and automotive components with components namely Na2O and K2O can increase acid resistance and increase water absorption. Non-dental glass fiber is widely available in Indonesia at an affordable price can be an alternative substitute for E-glass dental fiber whose availability is limited in Indonesia and the price is relatively high. The purpose of this study was to analyse the effect of the amount of non-dental glass fiber on reinforced acrylic resin on the attachment of C. albicans. Methods: This type of research is a laboratory experiment with a Posttest Control Group Design that was conducted to determine the effect of the number of non-dental glass fiber on reinforced acrylic resin on the attachment of C. albicans with 12 samples grouped into 3 groups, namely 0.9% non-dental glass fiber, non dental glass fiber 1.8%, and without fiber. Statistical analysis using the Oneway ANOVA test with a p-value <0.05. Results: The study showed that non-dental glass fiber was 0.9% (average yield: 1.10), non-dental glass fiber was 1.8% (average yield: 1,125), and without fiber (average yield: 1,525) has a different but not significant effect. Conclusion: Addition of non-dental glass fiber to acrylic resin plates did not affect the attachment of C. albicans.Keywords: Non-dental glass fiber, fiber-reinforced acrylic resin, Candida albicans

Abstract

Pendahuluan: Kehilangan gigi salah satunya dapat diganti dengan gigi tiruan cekat untuk mengembalikan fungsi oklusi dan estetis.  Bahan gigi tiruan cekat antara lain porcelain fused to metal (PFM), namun PFM memiki beberapa keterbatasan diantaranya memerlukan preparasi gigi abutment cukup banyak yang dapat mempengaruhi vitalitas pulpa, salah satu alternatifnya digunakan fiber reinforced composite (FRC). Paparan saliva terhadap resin komposit menimbulkan proses penyerapan air yang mengakibatkan terjadinya perubahan dimensi. Tujuan penelitian untuk menganalisis perbedaan perubahan dimensi glass fiber non dental reinforced composite antara setelah 7 hari dan 14 hari perendaman dengan saliva buatan. Metode: Jenis penelitian ini adalah penelitian eksperimental laboratorium.Bahan penelitian yang digunakan yaitu FRC dengan matriks berupa resin komposit flowable (Master Flow, Brazil) dan glass fiber non dental. Sampel penelitian berbentuk balok ukuran 25x2x2 mm, sampel disinari menggunakan LCV selama 20 detik. Sampel berjumlah 8 buah dibagi menjadi 2 kelompok yaitu lama perendaman 7 dan 14 hari. Sampel direndam dalam saliva buatan dengan pH 7. Perubahan dimensi dihitung dengan dimensi akhir dikurang dimensi awal, diukur menggunakan caliper. Hasil: Analisa statistik menggunakan mann-whitney diperoleh nilai p= 0,017<0,05 artinya terdapat perbedaan perubahan dimensi glass fiber non dental reinforced composite. Simpulan: Semakin lama glass fiber non dental reinforced composite direndam dalam saliva buatan maka semakin besar perubahan dimensi yang terjadi.Kata kunci: Perubahan dimensi, glass fiber non dental reinforced composite, lama perendaman, saliva buatan ABSTRACTIntroduction: One of the lost teeth can be replaced with fixed dentures to restore occlusion and aesthetic function. Fixed denture materials include porcelain fused to metal (PFM), but PFM has several limitations including the preparation of abutments that can affect the vitality of the pulp, one of the alternatives is to use fiber-reinforced composite (FRC). Exposure to saliva to composite resins causes a process of absorption of water which results in dimensional changes. The purpose of this study was to analyse the differences in the dimensions of non-dental reinforced composite glass fiber between 7 days and 14 days of soaking with artificial saliva. Methods: This research is experimental laboratory research. The research material used is FRC with a matrix in the form of flowable composite resin (Master Flow, Brazil) and non-dental glass fiber. The research sample is in the form of a beam size of 25x2x2 mm; the sample is irradiated using LCV for 20 seconds. A total of 8 samples were divided into 2 groups: 7 and 14 days immersion. The sample is immersed in artificial saliva with a pH of 7. Dimensional changes are calculated with the final dimensions minus the initial dimensions, measured using a calliper. Results: Statistical analysis using Mann-Whitney obtained p-value = 0.017 <0.05 meaning that there are differences in the dimensions of the glass changes in non-dental reinforced composite glass fiber. Conclusion: The longer the non-dental reinforced composite glass fiber is immersed in artificial saliva, the greater the dimensional changes that occur.Keywords: Dimensional changes, non-dental reinforced composite glass fiber, immersion time, artificial saliva
