This study aims to determine the comparison of the inhibition zone between theextract of butterfly pea flower and lemongrass, against the bacteria streptococcusmutans and staphylococcus aureus. The samples that will be used in this researchare streptococcus mutans and staphylococcus aureus bacteria. Data analysis usednormality test and statistical test was performed using ANOVA analysis test and posthoc test. The results showed that there was no difference in the inhibition zone ofbutterfly pea flower extract against streptococcus mutans bacteria and lemongrassextract against streptococcus mutans. There was difference in the inhibition zonebetween butterfly pea flower extract against staphylococcus aureus bacteria andlemongrass extract against staphylococcus aureus bacteria. Butterfly pea flowerextract has a good inhibition zone in staphylococcus aureus bacteria. Lemongrassextract has the same inhibition zone against both types of bacteria
Background. This research is a study that seeks to explore the potential of robusta coffee bean extract in inhibiting the growth of Staphylococcus aureus bacteria, where this bacterium is one of the bacteria that is often found in the oral cavity and often causes infections and dental and oral problems. Methods. This research is an experimental study in vitro. Robusta coffee extract was tested at levels of 25%, 12.5%, 6.25%, and 3.125%, where each test group was tested on 6 plates of Staphylococcus aureus bacteria. Data analysis was carried out with the help of SPSS 25 software. Results. There was a significant difference in the inhibitory power of Robusta coffee extract (Coffea robusta) at concentrations of 25%, 12.5%, 6.25%, 3.125% on the growth of Staphylococcus aureus bacteria. Significant differences in inhibition were found in group I and II (p=0.002; mean diff = -0.83), group I and III (p=0.000; mean diff = -1.32), group I and IV (p= 0.000; mean diff = -2.12), group II with III (p=0.050; mean diff = -0.48), group II with IV (p=0.000; mean diff = -1.28), and group III with IV (p=0.002; mean diff = -0.80). Conclusion. Robusta coffee bean extract (Coffea robusta) has antibacterial activity against the growth of Staphylococcus aureus bacteria.
Background: Currently, the interest and awareness to maintain oral health is increasing, it is no longer limited to fillings and extractions, one of which is orthodontic treatment. The increasing interest in orthodontic treatment is due to the high prevalence rate of malocclusions consisting of mild to severe malocclusions. Patient non-compliance with scheduled visits is an indication of the failure of orthodontic treatment. Repeated failures will reduce the quality of care. Malocclusion is an abnormal dentofacial condition with or without impaired craniofacial connection. Malocclusion can affect facial aesthetic appearance, mouth function, and psychosocial. Malocclusion is the most common dental problem with a high prevalence ranging from 20% to 100% reported in various studies. Multifactorial causes of malocclusion, namely heredity, environmental factors or a combination of the two in individuals with malocclusion. Purpose: This study aimed to determine the level of adherence to control of fixed orthodontic patients based on the characteristics of students at the Faculty of Dentistry at the Prime University of Indonesia during the pandemic. Method: This research is non-experimental research with an observational descriptive method. The study was conducted on students of the Faculty of Dentistry, Universitas Prima Indonesia with a total sample of 30 people. Results: Based on the results of the research, it was concluded that the level of adherence to fixed orthodontic control of students during the Covid-19 pandemic was low and there was no relationship between characteristics and the level of patient compliance during the pandemic. Keywords: Malocclusion, Orthodontics, Dentofacial, Covid-19.
Diabetes Mellitus (DM) is a metabolic disorder characterized by high blood glucose levelsassociated with periodontal disease and increased levels of inflammatory biomarkers such asinterleukin. Therapeutic effects of molecular hydrogen for a wide range of disease models and humandiseases have been investigated. This review aims to systematically analyze and review animal andhuman studies investigating the effect of HRW on periodontal tissues, interleukin, or blood glucoselevels. An electronic search was conducted via PubMed/Medline, Google Scholar, Wiley Online Library,LILACS, Science.gov, and Cochrane Central Register of Controlled Trials (CONTROL) using thekeywords "Hydrogen Water", "Diabetes Mellitus", "Interleukin" and "Periodontal disease" for studiespublished between January 2011 to May 2021. After the elimination of duplicate items, the primarysearch resulted in 101 articles. After excluding irrelevant articles based on abstract and title, full texts of45 articles were read to exclude additional unrelated studies. Eight studies were included in this reviewfor qualitative analysis. The results showed that Drinking HRW exerts certain antioxidants for oxidativegingival stress and anti-inflammatory effects by decreasing interleukin and decreasing blood glucoselevels for DM patients. KEYWORDS: HRW, DM, Periodontal disease, interleukin
In performing the orthodontic treatments, patients aim to improve their smile esthetical features which are influenced by the position, size, shape, and color of teeth. However, in recent decades, several aesthetical features that have been studied are buccal corridor, smile arc, incisor display, and gingival display. In this study, 32 subjects composed of 16 males and 16 females were photographed from the front-site by using a DSLR camera within smiling states. Smile arc and buccal corridor measurements were performed via Corel Draw 12 program. The extra broad and broad characteristics were found in male subjects which were 31.2% and 18.8% respectively, while the female subjects had a higher broad proportion of 43.7% and extra broad for 6.3%. The smile arc features in male subjects were found were straight smile (34.4%) and consonant smile (15.6%), in contrast, the percentage of the female students had a higher consonant smile (31.3%) than straight smile (18.8%). This study confirmed similar findings regarding the domination of the buccal corridor broad in the female population, whereas the extra broad is dominated by males. By contrast, the smile arc consonant is dominated by females, while the straight feature is dominated by males.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
