Abstract:
OBJECTIVE:To assess the bioactivity, water sorption and solubility of sol-gel formulated glass-ionomer cement (FGIC) (60%SiO2, 35%CaO, 5%P2O5) with and without incorporation of Nano-fluorapatite (Nano-FAp) regarding to the commercial glass ionomer cement (CGIC).
MATERIAL AND METHODS: The tested glass-ionomer cement was formulated by sol-gel method and nano-fluorapatite was incorporated into this formulated glass-ionomer with different percentages (1wt%, 2wt%, 3wt%, and 4wt %). A total number of 216 samples were used in this study. The samples were categorized in six groups; group1 CGIC (negative control), group 2; FGIC (positive control), group 3; FGIC/1wt% Nano-FAp, group 4; FGIC/2wt% Nano-FAp, group 5; FGIC/3wt% Nano-FAp; and Group 6; FGIC/4wt% Nano-FAp. Each group was subdivided into two subgroups of (18) samples each according to type of the test.The samples were characterized and tested for bioactivity after immersion in simulating body fluid (SBF) for 28 days, and for water sorption and solubility after 7 days of immersion in distilled water. One-way ANOVA tests was used to analyze data statistical significant is stablished at probability level of 0.05.
RESULTS: FGIC recorded higher Ca/P ratio when compared to CGIC and this ratio increases with the increase of the percentage of the added nano-FAp. Also, FGIC recorded higher water sorption and solubility when compared to CGIC and its water sorption and solubility decreased when the amount of added nano-FAp increased.
CONCLUSION: The sol-gel formulated GIC has higher bioactivity, higher water sorption and solubility than the commercial GIC. However, the incorporation of nano-FAp improves the bioactivity of this sol-gel formulated GIC and decreases its water sorption and solubility along with the increases in concentrations.

Abstract:
Nanotechnology has recently emerged as a critical antimicrobial strategy. We developed a novel fluoride-containing zinc-copper nanocomposite (FZC). This study aimed to investigate the antibacterial effect of the nanocomposite and its effect on cell activity.A fluoride-containing zinc-copper nanocomposite (FZC) was synthesized according to the previous study and observed SEM.We analyzed the antibiotic susceptibility of S. mutans (ATCC 25175) to different concentrations of FZC. The bacterial were cultured in BHI medium with FZC and incubated for 24 h at 37°C. The antibacterial effect was calculated by the colony-forming units (CFUs). Cell viability assay was measured using hDPSCs cultured with Dulbecco's modified Eagle's medium and 10% aqueous solution. After that, Cell viability was measured by the Cell counting Kit-8. The control BHI medium allowed bacterial growth, whereas Ca (OH)2 and ZCF(350 mg/ml, 87.5 mg/ml, 21.9 mg/ml) allowed no bacterial growth. The cell activity of FCZ was 80% that of the control.The fluoride-containing zinc-copper nanocomposite developed in this study had higher antimicrobial activity than calcium hydroxide. Even if it's diluted 1000 times, it showed a little antibacterial effect. However, it affects cell activity with no lethal effects.

Analysis of Hemoglobin Levels on Menstrual Duration in Students for the 2017 Class of Faculty of Medicine University Muslim Indonesia

• Rasfayanah


• Indonesia

Abstract:
Hemoglobin (Hb) which is the main component of red blood cells (RBC) is a conjugated protein that functions as the transport of oxygen (O2) from the lungs to the tissues and carbon dioxide (CO2). Anemia is a common condition diagnosed based on laboratory results in which the hemoglobin concentration is abnormally low or the red blood cell count is decreased. Anemia in adolescent girls is still quite high, according to the World Health Organization (WHO, 2013), the prevalence of anemia in the world ranges from 40-88%. Adolescent girls have a ten times greater risk of suffering from anemia compared to young men. This is because young women experience menstruation every month and are in a period of growth so they need more iron intake. The purpose of the study was to determine the relationship between the length of menstruation and changes in hemoglobin levels in FK UMI students class 2017. This study used a descriptive analytical observational research design with a cross-sectional approach. The population in this study were students of the Faculty of Medicine, Muslim University of Indonesia class 2017. The sample size in this study used a purposive sampling technique, namely all students of the UMI medical faculty class 2017. Data analysis was carried out by univariate and bivariate analysis. The results of the study showed that 91.2% of female students had normal menstrual periods and 8.8% had hypermenorrhea. Changes in female Hb levels before and during menstruation were found to be 61.8% decreased and 38.2% increased. Based on data analysis, it can be concluded that there is no relationship between the length of menstruation and changes in hemoglobin levels in respondents.

Abstract:
Osteosynthesis of fractured fragments at the mandibular angle region proves to be a controversial topic. Many studies have shown that no single approach to fixation is ideal. Champy's plate is vulnerable to torsional and bending forces along the long axis of the mandible leading to flaring of fragments, loss of friction lock and result in reduced primary stability. 3 Dimensional (3D) miniplate consisting of two miniplates joined by interconnecting struts that act as a single unit. The plate is strong enough yet malleable facilitating stabilization both at superior and inferior borders. This study was carried out to evaluate the efficacy of 3D titanium mini plate for fixation of mandibular angle fractures.
Materials and Methods: This randomized prospective study consisted of 10 patients who met the inclusion and exclusion criteria. The patients were selected irrespective of the age, sex and socioeconomic status, presenting with mandibular angle fracture with or without associated secondary fractures. 3D titanium miniplate was used for fixation of fracture and patients were followed up for 4 months postoperatively.
Results: The mean interval between initial trauma to definitive fixation (IT-DF) was 4.7 days and mean time interval for plate adaptation to definitive fixation (PA-DF) intraoperatively was 26 minutes. No patients sustained any infections or permanent complications postoperatively and functional return to normal was adequate.
Conclusion: 3D titanium miniplate is an excellent choice for fast as well as reliably stable fixation of mandibular angle fractures.
