Abstract

Glass Ionomer Cement (GIC) memiliki sifat-sifat yang menguntungkan sebagai material restorasi. Namun, penggunaannya terbatas karena GIC memiliki kekuatan tekan yang rendah. Berbagai penelitian dilakukan untuk meningkatkan kekuatan tekan GIC, salah satunya penambahan hidroksiapatit ke bubuk GIC. Hidroksiapatit dapat disintesis dari larutan kimia atau berbagai limbah alam, misalnya cangkang telur, melalui metode presipitasi. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan hidroksiapatit dari cangkang telur terhadap kekuatan tekan GIC Fuji IX (GC Corporation). Pembuatan 32 silinder GIC berdiameter 4mm dan tinggi 6mm dibagi menjadi 2 kelompok, yaitu: kelompok GIC tanpa penambahan hidroksiapatit sebagai kelompok kontrol (n=16) dan kelompok GIC dengan penambahan 8% hidroksiapatit sebagai kelompok uji (n=16). Kekuatan tekan diukur dengan Universal Testing Machine. Data dianalisis menggunakan uji T tidak berpasangan. Hasil pengukuran rata-rata kekuatan tekan GIC kelompok kontrol adalah 104,33±1,36 MPa dan kelompok uji adalah 109,52±1,58 MPa. Hasil uji T pada data tersebut menunjukkan perbedaan signifikan antar kelompok (p

Abstract

Glass ionomer cement (GIC), restorative material in dentistry, are composed of glass powders and polyacrylic acid. GIC can release fluoride that acts as an antibacterial. Various study had been conducted to improve that antibacterial properties, but it can affect the physical and mechanical properties of GIC. The purpose of this study was to determine the effect of addition of triclosan antibacterial agent on the setting time of GIC. To obtain 2.5 % triclosan, 0,25 gram of triclosan powder was mixed into 9,75 gram of GIC powder. The sample was divided into 2 groups: control group (n=16) and treatment group (n=16). The setting time was measured using gilmore needle, by penetrating a needle to the surface of specimens with an interval of 10 seconds until the needle left no traces on the surface of specimens. Statistical analysis was done byT-test. The result showed that p value > 0,05. The conclusion is the addition of triclosan antibacterial agent do not affect the setting time of GIC

Abstract

Hydroxyapatite (HA) is a bioceramic with excellentbiocompatible properties, and composition and crystal structure similar to apatite in the human dental structure and skeletal system. A number of researchers have attempted to evaluate the effect of the addition of HA powders to increasemechanical properties of restorative dental materials. In this study, HA was synthesized using chicken eggshell as calcium source for synthesizing HA by using precipitation technique. The aim of this study was to determine the effect of incorporation of eggshell-derived HA on the surface hardness GIC (Fuji IX GP). Specimens were divided into two groups: group GIC without incorporation of HA as control group (n = 16) and group GIC with incorporation of 5% HA as experimental group (n = 16). Total of specimens were 32 cylinders 5mm diameter and 2mm height. Surface hardness GIC was measured with vickers microhardness tester. Data wasanalyzed by unpaired T-test. The mean of surface hardness for GIC control group was 51.37 ± 1,63VHN and the experimental group was 56.60 ± 1,22HVN. The results T-test showed a significant difference between groups (p<0.05). It can be concluded thatincorporation of eggshell-derivedHA could increasesurface hardness of GIC.

Abstract

Streptococcus mutans is a microorganism that important in dental caries. Herbs are known to have antibacterial activity against oral bacteria. The rhizomes of Curcuma longa and Curcuma zedoaria are two of the eight species of genus Curcuma that are most widely used as traditional herbal medicine in Indonesia. Both rhizomes have antibacterial activity against oral bacteria at a concentration of 12.5%. This study aimed to examine the inhibitory of Curcuma longa and Curcuma zedoaria rhizomes extracts against the growth of Streptococcus mutants. The study was in vitro study. Both rhizomes got from the Experimental Garden of Balittro Manoko Lembang, West Java, Indonesia. The maceration was employed to obtain the extracts with the final extracts of both rhizomes at a concentration of 12.5%. Antibacterial activity test was carried out by using the agar well diffusion method. The positive control group was 0.2% Chlorhexidine and distilled water as a negative control group. The data obtained were then analyzed using the One Way ANOVA Test and Post Hoc Test. Results showed that chlorhexidine 0.2% had the largest mean diameter of the inhibition zone. Curcuma longa rhizome extract had a larger mean diameter of inhibition zone compared to Curcuma zedoaria rhizome extract. However, the difference in the mean values of the two rhizomes extracts was not statistically significant. Distilled water didn't have antibacterial activity. It can be concluded that both Curcuma longa and Curcuma zedoaria rhizomes extracts at a concentration of 12.5% have antibacterial activity against Streptococcus mutans.
