Abstract

Karies merupakan penyakit multifaktorial yang diawali dengan proses demineralisasi jaringan keras gigi. Bakteri Streptococcus mutans merupakan mikroorganisme yang berperan sebagai faktor utama penyebab karies gigi. Senyawa antimikroba dari keju cheddar yaitu lactoferin, lisozim dan laktoperoksidase, sedangkan senyawa  antimikroba dari yoghurt plain adalah hydrogen peroksida, reuterin dan bakteriosin.Penelitian ini bertujuan mengetahui efektifitas antimikroba dari keju cheddar dan  yoghurt plain terhadap pertumbuhan bakteri Streptococcus mutans. Penelitian ini menggunakan metode eksperimen laboratoris dengan rancangan penelitian post test only group design, yang membandingkan ekstrak keju cheddar dan yoghurt plain dengan berbagai macam konsentrasi yaitu 25%, 50%, 75% dan 100%. Penelitian dilakukan dengan cara merendam kertas cakram dalam berbagai konsentrasi tersebut selama ±15 menit. Kemudian kertas cakram diletakkan pada permukaan MHA Plate yang telah diberi bakteri Streptococcus mutans standart Mac Farland III lalu inkubasi selama 24 jam dengan suhu 370C. Hasil diameter zona hambat yang  terbentuk diukur lalu diuji menggunakan uji Kruskal-Wallis dan uji Mann-Whitney. Rerata dan simpang baku dari diameter zona hambat keju cheddar 100% sebesar 6,750 ± 0,1378 mm, keju cheddar 75% sebesar 5,767 ± 0,6055 mm, sedangkan keju cheddar 50% dan 25% tidak terbentuk zona hambat. Pada yoghurt plain rerata dan simpang baku dengan konsentrasi 100% sebesar 5,667 ± 0,0816 mm, konsentrasi 75% sebesar 5,650 ± 0,0548 mm, sedangkan konsentrasi 50% dan 25% tidak terbentuk zona hambat. Berdasarkan uji Kruskal-Wallis untuk menguji hipotesa yang membandingkan rerata > 2 kelompok perlakuan, didapatkan nilai signifikan 0.00(p<0.05), sehingga ada perbedaan efektifitas antimikroba antara keju cheddar dan yoghurt plain terhadap pertumbuhan S.mutans. Uji Mann-Whitney untuk mengetahui kelompok yang memiliki mean yang berbeda secara siginifikan,   menunjukkan hanya sebagian kecil kelompok perlakuan saja yang mempunyai nilai p>0,05 atau tidak signifikan, sebagian besar kelompok perlakuan terdapat perbedaan yang signifikan dengan nilai p<0,005. Kesimpulan dari penelitian ini, terdapat  perbedaan efektifitas antimikroba antara keju cheddar dan yoghurt plain terhadap pertumbuhan bakteri S.mutans dimana keju cheddar memiliki efektifitas antimikroba yang lebih baik terhadap S.mutans jika dibandingkan dengan yoghurt plain. Semakin tinggi konsentrasi yang digunakan pada keju cheddar dan yoghurt plain, maka semakin besar pula zona hambat yang terbentuk. Keju cheddar dengan konsentrasi 100% memiliki efektifitas antimikroba yang lebih baik terhadap bakteri Streptococcus mutans, jika dibandingkan dengan yoghurt plain.

Abstract

Background: Acrylic resin is a dental material that is often used because it is easy to apply and has good aesthetics. One type of acrylic resin used for denture base materials in dentistry is Heat Cured Acrylic Resin (HCAR). HCAR as base for dentures also has disadvantages including low tensile strength. Therefore, fiber can be added to heat cured acrylic resin as a reinforcing material (FRAR). This study aims to determine the effect of the addition of non-dental glass fiber on the tensile strength of HCAR.Method: This is a true experimental research using posttest only control group design. Divided into two groups, the first one is HCAR without the addition of non-dental glass fiber, the second group is HCAR with the addition of non-dental glass fiber. The data are tested using the Independent T-Test parametric test.Result: The average tensile strength of the HCAR without Non Dental Glass Fiber was 46.5169 MPa, while the average tensile strength of HCAR with the addition of Non Dental Glass Fiber was 60.3269 MPa. The independent test results show p value of = 0.000Conclusion: It was found that heat cured acrylic resin with the addition of non-dental glass fiber has a higher tensile strength than heat cured acrylic resin without the addition of non-dental glass fiber which could be used as an alternative choice in applications in dentistry.

Abstract

Background: Glass ionomer cement (GICs) has become a common restorative material in dental practice. Therefore, there are so many GIC's brands can be found in the market with tremendous price disparities GIC brands can be found in the market with huge price disparity; Price of one brand can be up to tenfold than the others. For the cost-efficiency reason, many clinicians prefer the more economical. Therefore, questions arise from the clinician, does it influence the clinical performance. Method: Six cylindrical specimens (10mm x 2mm) from four GIC brands (Fuji IX, FXUltra, GlassyCem and Sangchi) were made based on the respective factory instructions and stored for 24 hours until the final setting reached. Micro Vickers hardness tester (Shimadzu) and Surface roughness tester were used as surface characterizations measurement. Collected data were analyzed statistically. Results: Kruskal-Wallis and Mann-Whitney analysis showed that Fuji IX and FXUltra significantly (p<0.05) higher surface hardness (68.47 and 63.29 VHN respectively) compared to GlassyCem and Sangchi (38.53 and 36.70 VHN). While for surface roughness measurement, Fuji IX has the highest surface roughness, 7.22 µm (p<0.05). GIC’s clinical performance is affected by composition and powder-liquid ratio. Strontium in Fuji IX could increase surface hardness. The high powder-liquid ratio in Fuji IX and FXUltra improve its clinical performance compared to the other group. Conclusion: The more expensive GIC (Fuji IX and FX ultra) had better surface hardness with a slight difference in surface roughness. Therefore, clinicians should choose GIC based on cost-efficiency without ignoring clinical performance.

Abstract

Background: Fiber reinforced composite is a combination of composite resin and fiber. Fiber in FRC serves as a reinforcement to be resistant to fractures. One of the fibers used in FRC is dental glass fiber because it can increase mechanical strength. Dental glass fiber is very limited and expensive while glass fiber which available in the market is non dental glass. This material has mechanical properties almost same as dental e-glass fiber used in dentistry, so it can be used as an alternative material FRC. The aim of this study was to identify the effect of flexural strength of non dental glass fiber to prepolymerized fiber reinforced composites.Method: This study used true experimental design with 16 samples. The samples were divided into two groups according to prepolymerized composite resin groups without fiber and prepolymerized composite resins with the addition of non dental glass fiber. Data analysis in this study used the normality test with the Sapiro-Wilk test, levene test and independent t-test. Result: The results were statistically analyzed, the average flexural strength of prepolymerized composite resin without fiber is 36.60 MPa and prepolymerized composite resin with the addition of non dental glass fiber which is 54.26 MPa. Based on the normality test and the levene test values (p> 0.05) and independent t-test values (p <0.05) were obtained.Conclusion: The conclusion obtained that there is an effect of the addition of non dental glass fiber to the flexural strength of prepolymerized fiber reinforced composite.
