EFEK PASTA GIGI EKSTRAK ETANOLIK TEH SEGAR 2% DAN EPIGALLOCATECHIN GALLATE EKSTRAK TEH 0,1% TERHADAP INDEKS PLAK GIGI: EFFECT OF 2% TEA LEAF ETHANOL EXTRACT AND 1% EPIGALLOCATECHHIN GALLATE TEA LEAF TOOTH PASTE TO DENTAL PLAQUE INDEX
Full text linkGreen tea (Camellia sinensis) has been widely known as a healthy beverage for years and the most polyphenolcomponents (catechin) of tea is Epigallocatechin gallate (EGCG). The aim of this study was to evaluate the effectivenessof tea leaf ethanolic extract toothpaste and EGCG toothpaste on dental plaque index. The subjects were 45 girls, 10-12yeras old, under ethical clearance from Ethic Comittee Medical Faculty of Gadjah Mada University, YogyakartaIndonesia. The subjecs were divided into 3 groups based on caries status (Group I), gingivitis status (Group II) andhealthy status (Group III). Each group consisted of 15 subjects, and divided into 3 sub groups based on toothpaste (tea leafethanolic extract toothpaste, EGCG toothpaste, and base material toothpaste as control). The subjects were instructed tobrush their teeth during 21 consecutive days in the morning and at night. Clinical evaluation was done by PHP Index.Data were taken before treatment in the 7th, 14th and 21st day. Then, they were analyzed using ANOVA and LSD tests.The results showed that the index of PHP was significant difference in each group after using leaf ethanolic extracttoothpaste, EGCG toothpaste, and base material toothpaste. This study suggested that the leaf ethanolic extract toothpasteand EGCG toothpaste could have effected to decrease the PHP Index. As conclusion, the leaf ethanolic extract toothpasteis more effective than the EGCG toothpaste to decrease the PHP Index
CORRELATION BETWEEN CALCIUM BENTONITE CONCENTRATION AND PARAFFIN WAX TO THE HARDNESS OF CARVING WAX: HUBUNGAN ANTARA KONSENTRASI KALSIUM BENTONIT DENGAN PARAFIN MALAM TERHADAP KEKERASAN MODEL MALAM
Full text linkThe carving wax composes many natural or synthetic waxes and sometimes filler is added physical and mechanicalproperties. The aim of this study was to determine the correlation of concentration Ca-bentonite carving wax compositionand the hardness. The paraffin, carnauba wax, bees wax, Ca-bentonite, and inlay wax were used in this research. Thecarving wax compositions were made of paraffin, Ca-bentonite, carnauba wax, and bees wax ratio (% weight): 50:20:25:5(KI), 55:15:25:5 (KII), 60:10:25:5 (KIII), 65:5:25:5 (KIV), 70:0:25:5 (KV). All components were melted, then pouredinto hardness moulds (n=5). The carving wax properties were tested of their hardness by penetrometer (Setamatic, UK).Data were analyzed statistically by regression test and linearity by Anova. The results showed that regression linearsignificantly (p<0.05) and the regression of equation was Y = 18.365-50.940 X with coefficient regression of (R) = 0.922(p<0,05) and determinant factor 84.9 percent. The conclusion of this study was the adding of Ca-bentonite on thecomposition of carving wax improved its hardness with the significant linearity (p<0.05)
PENURUNAN AKTIVITAS FAGOSITOSIS SEL MAKROFAG MENCIT SETELAH DISTIMULASI MINYAK ATSIRI KENCUR TERHADAP ACTINOBACILLUS ACTINOMYCETEMCOMITANS: REDUCING OF PHAGOCYTOSIS ACTIVITY OF MOUSE MACROPHAGE CELL AFTER STIMULATION KAEMPFERIA GALANGA LINNEUS TOWARDS ACTINOBACILLUS ACTINOMYCETEMCOMITANS
Full text linkMacrophage plays an essential role in innate immune system by phagocytosing bacteria. However, the phagocytosisprocess may activate macrophage to release inflammatory mediators which may cause tissue destructions in strongreaction. Kaempheria galanga L. is one of medical plants which is believed having potency as an immunomodulatoragent. The aim of this study was to examine macrophage cells phagocytic activity of Actinobacillus actinomycetemcomitans after stimulated with Kaempheria galanga`s essential oil in vitro. Mouse peritoneal macrophages wereincubated with 5%, 10%, and 20% of Kaempheria galanga`s essential oil at 37oC in an atmosphere containing 5% CO2.After 15 minutes, A. actinomycetemcomitans was added to the suspension and incubated for 30 minutes. At the end of theincubation period, the cells were assayed for the phagocytic activity. The result of this study showed that Kaempheriagalanga`s essential oil significantly reduced the percentage of mouse macrophage cells phagocytosing A. actinomycetemcomitans and the number of phagocytosed A. actinomycetemcomitans per 1 macrophage cell in vitro (p<0,05). Inconclusion, Kaempheria galanga`s essential oil may reduce mouse macrophage cells phagocytic activity of A.actinomycetemcomitans
