Penyerapan Air Glass Fiber Non Dental – Fiber Reinforced Composite dalam Larutan Mouthwash

Fiber reinforced composite (FRC) is widely used to replace porcelain fused to metal (PFM) for patients who have lost teeth. Fiber reinforced composite is  resin matrix protheses with fiber reinforced to get optimal strength. Glass fiber dental is often used because it does not require complex preparations, not sensitive to chemicals and moisture, but it has an expensive price for Indonesian people and limited availability. An alternative material such as glass fiber non dental can used. Mouthwash is used as an antiseptic and anti-plaque material on the oral cavity. Mouthwah can affect of water sorption of FRC. The aim of this study is to know effect of mouthwash on the absorption of water in non dental glass fiber - reinforced FRC.  Sixty specimens divided into four groups (n=4), 2 groups with glass fiber dental soaked on the bisguanida and aquades, 2 groups with glass fiber non dental soaked on the bisguanida and quaternary ammonium. The data analyzed with Anova. Anova test showed that there is an influence of mouthwash bisguanide and quartenary ammonium compounds on the value of absorption of glass fiber reinforced composite water (p<0,05). Water sorption of FRC in bisguanide mouthwash is higher than quartenary ammonium compounds

Samples were divided into 4 groups, immersion of the sample in 100% ascorbic acid within 2, 3 and 4 days, and the control group immersed in sterile aquades. Tooth color measurements before and after immersion with a spectrophotometer. One Way ANOVA test results (p <0.05) showed a significant difference between treatment groups. Post-Hoc test results can be concluded that the 2 day immersion is the most effective in improving the color of teeth with a mean rank is 39.47. From the results showed that the comparison of 2 day immersion group was the most effective for increase the color of teeth than 3 day and 4 day immersion groups

Perbandingan Aktivitas Antibakteri Ekstrak Etil Asetat Daun Rasamala (Altingia excelsa noronha) dan Bahan Pengisi 3 Mix terhadap Enterococcus faecalis

Introduction : Lesion Sterilization and Tissue Repair (LSTR-3MIX) are new paradigm in caries care with or without involving pulp and periapical by using combination of three antibiotics. Bacteria that cause endodontic or root canal infection are dominated by Enterococcus faecalis, which is facultative anaerobic gram-positive bacteria and the bacteria are resistant against antimicrobial substance and often found in failed endodontic treatment. LSTR method is an effort that disinfects pulp lesions by killing the bacteria through using three antibiotics, which are metronidazole, ciprofloxacin, and minocyline. The use of several kinds of antibiotics can trigger the resistance of bacteria. However, it is needed an alternative of new antibiotic finding by using natural antibacterial herbal medicine as filler substance for endodontic that has antibacterial ability as balanced as 3MIX antibiotic pasta. Purpose : This research aimed at knowing the difference of antibacterial effect between rasamala leaf extract against E. faecalis bacteria that was compared with 3MIX antibiotic pasta. Method : The method used in this research was laboratory experiment by utilizing post test only control group design. This research was consisted of 6 treatment groups of rasamala leaf extract with concentration of 20%, 10%, 5%, 2,5%, 1,25%, and 1 control group of 3MIX antibiotic pasta. Result : 3MIX antibiotic was more effective in inhibiting the growth of bacteria rather than rasamala leaf extract in inhibiting the growth of Enterococcus faecalis. Conclusion : ethyl acetate from rasamala leaf extract was not more effective than 3MIX antibiotic in inhibiting the growth of Enterococcus faecalis

Efektivitas Asam Askorbat Buah Alpukat (Persea americana Mill.) Terhadap Pemutihan Gigi

Teeth discoloration has been complained by most of Indonesians. A treatment of teeth discoloration can be overcome by using a bleaching treatment. Bleaching itself, can be done using a natural ingredients, for instance avocado (Persea americana Mill.),which contained an ascorbic acid for a dental bleaching. The aim of this study is to find out the effectiveness of avocado with concentrations of 30%, 70%, and 100% on a teeth bleaching. It is a laboratory experimental research using a pretest-posttest control group design. The sample used are 24 post-extraction of premolar teeth, and ascorbic acid which was taken from the avocado by an isolation method. The teeth soaked in a black tea for 6 days and replaced every 2 days, then soaked with ascorbic acid in the avocado extract 30%, 70%, 100%, and control aquades for 3 days.The degree of teeth color was measured by using a spectrophotometer. The data analysis used a discrimination test with One Way Anova and further discrimination test with Pos Hoc Anova. The results of discrimination test with One Way Anova showed the significant value was 0,019 (p<0,05), which means there was difference colour between before and after the soaking teeth treatment using the ascorbic acid in avocado with concentrations of 30%, 70%, and 100%. Based on Pos Hoc Anova test, showed that 30% and 100% concentrations of ascorbic acid is more effective than the aquades. As the 100% concentration of ascorbic acid showed a demineralization. Therefore the 30% concentration of ascorbic acid is the most effective. The ascorbic acid in avocado extract (Persea americana Mill.) with 30%, 70%, dan 100% concentrations is effective for a dental bleaching

Pengaruh Gigi Molar Tiga Atas pada Kejadian Perikoronitis Gigi Molar Tiga Bawah

The impaction of the lower third molar is an impaction that commonly happens, approximately 98% of 10.979 impacted molars found in the study on 5.000 cadets. The condition of the impaction tend to cause several pathological conditions, which one of them is pericoronitis, where this condition at once becomes one of the most reasonable reasons for extraction on the involved impacted molars to be performed. The aim of this research was to identlfv the eflects of the upper third molar on the existence of pericoronitis of the lower third molar: Design of this research was an analytical observational study using the cross sectional approach over 6 months. This research was conducted through the direct observation and roentgen photo on 62 patients with the impaction of the lower third molar either with pericoronitis or without pericoronitis in the hospital of RSU PKU Muhammadiyah Yogyakarta. The observation was done to the patients with pericoronitis to idenhjy the correlation between the traumatic occlusion with the appearance of pericoronitis. The observation was also conducted to identijjz the correlation between the level of impaction with the traumatic occlusion and the correlation between the position of the upper third molar with the traumatic occlusion. During the research, there gained 62 sampels was gained, divided into 29 samples with pericoronitis and 33 samples without pericoronitis. The occurrence of the pericoronitis with trauma was mostly seen on the level A of impaction with the position of the upper third molar is bucoversion (90,9%), while the occurrence of pericoronitis without trauma was mostly seen on the vertical upper third molar with level B of impaction (83,3%). From the analysis test of Chi-Square, showed a significant correlation between the traumatic occlusion with the occurrence of pericoronitis (z20, 05) and there was an efiect of the upper third molar position and the impaction level with trauma (p0,05), while the upper third molar with pericoronitis and the impaction level with pericoronitis did not show any significant influence Q20,05). The analysis test of Man-Whitney showed that the bucoversion upper third molar position mostly caused trauma (p0, 05). Upper third molar; the impaction level and the trauma with recurrent pericoronitis or first pericoronitis did not show any significant influence (p0, 05)
