Abstract

Fiber reinforced composite (FRC) resin can improve color stability. The most commonly used fiber in dentistry is E-glass fiber, but dental E-glass fiber has limitations and is expensive. The composition of non-dental E-glass fiber is almost the same but the concentration is different. E-glass fiber is difficult to adhere to composite resin so it requires silane coupling agent as a binder. The difference in color stability of E-glass fiber non dental reinforced composite with or without the addition of silane coupling agent was studied through quantitative research with laboratory experimental method using one group pretest and posttest de-sign. The samples were FRC plates obtained by purposive sampling method, 13 mm in diameter and 2 mm thick, which were divi-ded into 2 groups of E-glass fiber non dental with silane and without silane. The color stability test was carried out by Us-Vis spectrophotometer whose absorbance value and wavelength were calculated to determine the area value of l*a*b* in each sam-ple. Statistical analysis using independent t-test. Significant differences were found between non-dental E-glass fiber with silane and without silane. It was concluded that non-dental E-glass fiber with silane showed better color stability than without silane.

Abstract

Latar belakang: resin komposit merupakan bahan restorasi yang paling populer saat ini karena memiliki kelebihan estetik yang baik yaitu sewarna gigi, namun resin komposit memiliki keterbatasan sifat fisik yaitu penyerapan air. Penyerapan air dan waktu perendaman berpengaruh terhadap stabilitas warna. Alternatif yang dapat dilakukan untuk mengurangi penyerapan air dan meningkatkan stabilitas warna yaitu digunakan resin komposit yang diperkuat oleh Fiber Reinforced Composite (FRC). Fiber yang paling sering digunakan dalam kedokteran gigi adalah E-glass fiber, akan tetapi di Indonesia E-glass fiber dental memiliki keterbatasan jumlah yang terbatas dan harga relatif mahal. E-glass fiber non dental dipilih sebagai alternatif karena komposisinya hampir sama dengan E-glass fiber dental dan biasa digunakan di dunia teknik. Tujuan: penelitian ini bertujuan untuk mengetahui perbedaan stabilitas warna E-glass fiber non dental reinforced composite akibat lama perendaman dalam saliva buatan. Metode: jenis penelitian kuantitatif menggunakan eksperimental laboratorium menggunakan one group pretest and posttest design. Sampel berbentuk lingkaran dengan diameter 13 mm dan tinggi 2 mm yang terdiri dari 2 kelompok; kelompok perendaman 7 hari dan 14 hari masing-masing terdiri dari 4 sampel. Uji stabilitas warna dilakukan dengan Spektrofotometer Uv-Vis dimana nilai absorbansi dan panjang gelombang yang didapat akan dihitung luas daerah sehingga dapat ditentukan nilai L*a*b* pada tiap sampel. Hasil: hasil rerata pengukuran stabilitas warna E-glass fiber non dental reinforced composite selama 7 dan 14 hari perendaman dalam saliva buatan menunjukkan nilai rerata 14 hari perendaman berada sedikit lebih tinggi dibandingkan 7 hari perendaman namun tidak bermakna. Uji independent sample t-test diperoleh nilai p=0,442 0,05 artinya tidak terdapat perbedaan yang signifikan antara perbedaan stabilitas warna E-glass fiber non dental reinforced composite akibat lama perendaman antara 7 hari dengan 14 hari. Kesimpulan: tidak terdapat perbedaan stabilitas warna E-glass fiber non dental reinforced composite akibat lama perendaman dalam saliva buatan. Penambahan E-glass fiber non dental pada resin komposit menunjukan stabilitas warna yang baik pada resin komposit.

Abstract

Porphyromonas gingivalis is a gram-negative anaerobic bacterium involved in the pathogenesis of periodontal disease that can lead to tooth loss. One way to control P.gingivalis is by using chlorhexidine, but continuous use can eliminate the sensation of saltiness on the tongue. Avocado (Persea americana Mill) is one of the natural ingredients that can be utilised as medicinal and antibacterial plants because it contains several secondary metabolite compounds such as flavonoids, tannins, saponins and al-kaloids. The use of avocado peel as an antibacterial P.gingivalis is not yet known for certain so this research was conducted to determine the antibacterial activity of ethanol extract of avocado peel against P.gingivalis. The extract was obtained by extrac-tion using the maceration method, then tested for antibacterial activity of ethanol extract of avocado fruit peel against P.gingi-valis with concentrations of 20%, 40%, 60%, 80%, 100%, chloramphenicol 30 μg/μL as positive control and dimethyl sulfoxide as negative control. This test was conducted using the disc paper diffusion method. It is concluded that the ethanol extract of avocado fruit peel had antibacterial activity against P.gingivalis. The 20% concentration had an average inhibition diameter of 9.92 mm and 100% concentration inhibition of 16.36 mm.

Abstract

The fiber that is most often used in dentistry is E-glass fiber, but in Indonesia E-glass fiber dental is limited by quantity and relatively expensive. E-glass fiber non dental was chosen as an alternative because the composition is almost the same as E-glass fiber dental and commonly used in the engineering world as a booster in the manufacture of gypsum panels, sculptures and automotive components. This study is aimed to determine the color stability difference between fiber reinforced composite (FRC) E-glass fiber dental and E-glass fiber non dental. This quantitative research is an experimental laboratory with a one group pretest and posttest research design. The sample is circular in shape with diameter 13 mm and height 2 mm consisted of E-glass fiber dental group and the E- glass fiber non dental group consisting of 4 samples for each group and given silane. After the color test using Spectrophotometer UV-Vis where the absorbance and wavelength values obtained will be calculated for the area so that the L*a*b* value and analysed using independent sample t-test, it was stated that there was no significant difference between the color of the fiber reinforced composite E-glass fiber dental and the E-glass fiber non dental. It is concluded that the use of E-glass fiber non dental can be used as a clinical standard because it has a good color stability value similar to that of E-glass fiber dental.

Abstract

ABSTRAKPendahuluan Gigi tiruan menjadi solusi yang tepat untuk menggantikan gigi alami yang hilang. Gigi tiruan jembatan dengan bahan porcelain fused to metal paling sering digunakan dalam praktik klinis, namun memiliki kekurangan seperti rentan pecah, memerlukan beberapa kali kunjungan, dan membutuhkan preparasi gigi penyangga yang cukup luas. Alternatif bahan yang dapat digunakan untuk gigi tiruan cekat adalah Fiber reinforced composite dengan E-glass fiber dental yang memiliki kelebihan seperti biokompatibilitas baik, memiliki kekuatan kompresi, dan estetika yang baik. Ketersediaan E-glass fiber dental di Indonesia masih terbatas dengan harga yang cukup mahal. E-glass fiber non dental secara umum biasanya digunakan di bidang teknik, sedangkan E-glass fiber dental biasanya digunakan di bidang kedokteran gigi, namun keduanya memiliki komposisi yang hampir sama. Tujuan dari penelitian ini untuk mengetahui pengaruh posisi E-glass fiber non dental terhadap kekerasan Fiber reinforced composite. Metode: Penelitian berjenis eksperimental dengan perbedaan posisi E-glass fiber non dental yang digunakan dalam Fiber reinforced composite. Pengujian dilakukan pada 3 kelompok sampel yang terdiri dari kelompok posisi tension side, kelompok compression side, dan kelompok neutral axis, yang masing - masing terdiri dari 6 kali pengulangan, kemudian diuji dengan menggunakan alat uji kekerasan vickers hardness tester.  Hasil: Hasil pengujian pada Fiber reinforced composite dengan posisi E-glass fiber pada tension side menunjukkan kekerasan tertinggi dengan nilai = 45,77 VHN, sedangkan pada posisi neutral axis nilai kekerasan = 43,35 VHN, dan pada posisi compression side memiliki nilai terendah = 39,60 VHN.

Denture bridges made from porcelain fused to metal are most often used in clinical practice, but have disadvantages such as being prone to breaking, requiring several visits, and requiring extensive preparation of the abutment teeth. Alternative materials that can be used for fixed dentures are fiber-reinforced composites with E-glass dental fiber, which have advantages such as good biocompatibility, compression strength, and aesthetics. The availability of E-glass fiber dental in Indonesia is still limited, and the prices are quite expensive. Non-dental E-glass fiber is generally used in engineering, while dental E-glass fiber is usually used in dentistry; however their composition is very similar.The aim of this research is to determine the effect of the position of non-dental E-glass fiber on the hardness of fiber reinforced composite. Methods: Experimental research with fiber-reinforced composites using non-dental E-glass fiber in three different positions include the tension side position group, the compression side group, and the neutral axis group. Each group consisted of six samples and was tested using a Vickers hardness tester. Results: The test results on fiber-reinforced composite hardness showed the tension side position of the E-glass fiber had the highest hardness with a value of 45.77 VHN, the fiber on the neutral axis position had a value of 43.35 VHN, and the compression side had the lowest value of 39.60 VHN. Conclusions: The conclusion from this research is that the position of non-dental E-Glass fiber influences the hardness of fiber-reinforced composites.KEY WORDS: E-glass fiber, Fiber reinforced composite, fiber position, hardness
