Objective: To evaluate the quality, source, usefulness and/or reliability, visibility, and popularity of YouTube™ videos on oral candidiasis.
Materials and Methods:A YouTube™ search for "oral candidiasis" was performed, setting the English language. 133 of the 351 videos watched were included in the study.Two periodontologists scored the videos for visibility, popularity, quality, utility, and reliability. Videos' quality was evaluated using the DISCERN and the Global Quality Scale (GQS) tools, by categorizing them through quality assessment, source, duration, views, likes, and dislikes of each video were noted.Results: 82.7% of the videos were moderately or very useful, and the GQS scores were mostly good (41.4%-Score 4) and excellent (42.1%-Score 5). Significant relationships were obtained between Source of Upload, Video Type, Total Discern, and GQS variables and Usefulness scores (p < 0.05). The 53.4% of the video sources were Healthcare professionals and their video usefulness scores were mostly "moderately useful" (47.9%) and "very useful" (%42.3). There was a significant positive correlation between the usefulness scores of the videos and the number of likes (p = 0.004), comments (p = 0.019), and the viewing rate (p = 0.006).
Conclusions:The videos that rank high in searches for oral candidiasis on YouTube™ are mostly useful and comprehensive videos uploaded for educational purposes.
The aim of the present study was to evaluate the inhibitory effects of oxytocin on the development of periodontitis based on its properties against bone loss and resorption. Thirty-two Wistar albino rats were divided into four equal groups: control, periodontitis + saline, periodontitis + 0.5 mg/kg/day oxytocin, and periodontitis + 1 mg/kg/day oxytocin. Periodontitis groups received 4.0 silk ligatures around their cervixes of the right and left mandibular incisors in an "8" shape, kept for 14 days. Animals in oxytocin groups were injected once every day during 14 days with oxytocin. The mandibles were fixed and scanned using microcomputed tomography to quantify bone resorption and volumetric measurements. Blood samples were collected to analyze the concentrations of macrophage colony-stimulating factor (M-CSF), receptor activator of nuclear factor-κΒ ligand (RANKL), osteoprotegerin (OPG), matrix metalloproteinase-8 (MMP-8), tumor necrosis factor-alpha (TNFα), interleukin (IL)-6, glutathione peroxidase (GPx), superoxide dismutase (SOD), and malondialdehyde (MDA). Histopathological evaluations were conducted to examine the gingiva and alveolar bone. Oxytocin prevented the development of periodontitis by decreasing ligament deteriorations and leukocytes in the gingival connective tissue and promoting reintegration with the alveolar bone. Bone resorption in all regions was less in the periodontitis + 1 mg/kg/day oxytocin group than in the periodontitis + saline group. Although TNF-α, IL-6, and RANKL values were lower in the periodontitis + 1 mg/kg/ day oxytocin group, OPG was higher than that in the periodontitis + saline group. M-CSF, MMP-8, and MDA were lower in the oxytocin groups than in the periodontitis + saline group. Oxytocin may be an effective agent for periodontal diseases because it decreased bone resorption, oxidative stress, and inflammation in an experimental periodontitis.
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.
