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.

İmplant uzunluklarının ve tasarımının implant primer stabilite üzerine etkilerinin rezonans frekans analizi kullanılarak değerlendirilmesi: İn vitro bir çalışma Amaç: Primer stabilite (PS), implantın uzunluğuna ve çapına, implant yüzeyinin mikro morfolojisine, implant tasarımına, cerrahi prosedüre, kemik miktarına ve kalitesine bağlıdır. Bu çalışmanın amacı, çok kısa, kısa ve standard dental implantları Tip IV kemikte primer stabilitelerine göre Rezonans Frekans Analizi (RFA) test ekipmanı kullanarak karşılaştırmaktır. Gereç ve Yöntemler: Yetmiş iki dental implant; Large grit kumlanmış ve asitlenmiş (sandblasting with large grit particles and acid etching, SLA) (Dentium®, SimpleLine II, Seul, Kore), SLActive yüzey-(Straumann Roxolid®, Basel, İsviçre), Resorbable blast media (RBM) yüzey-(Implance®, Trabzon, Türkiye) çok kısa (4 mm uzunluğunda), kısa (6 mm uzunluğunda) ve standard dental implantlar (10 mm uzunluğunda) insan tip IV kemiğine benzer kemik kalitesine sahip sığır türü kaburgaya yerleştirildi. Grupları karşılaştırmak için tek yönlü ANOVA testi kullanıldı ve farklı gruplar post hoc Tukey testi ile değerlendirildi. Bulgular: Dört ve 6 mm uzunluktaki implantların İmplant Stabilite Katsayısı (Implant stability quotient, ISQ) ölçümleri benzerdi, ancak 10 mm uzunluktaki implantlarda gruplar arasında istatistiksel olarak anlamlı fark gözlendi. On mm uzunluğundaki implant grubunda SLActive yüzey en yüksek ISQ değerini gösterdi (p<0.005). Primer stabilite grup içinde karşılaştırıldığında, SLA yüzey ve RBM yüzey implantlarda önemli bir fark gözlenmezken 10 mm uzunluktaki SLActive yüzey implantı 4 ve 6 mm uzunluğundan daha yüksek ISQ değerine sahip bulundu (p<0.005). Sonuç: İmplant tasarımı ve yüzey özellikleri de çok kısa ve kısa implantlarda primer stabilitede etkili olabilir ve SLActive yüzey implantları, standart implantlarda daha iyi primer stabilite gösterebilir. ANAHTAR KELİMELER Dental implantlar, in vitro, kısa implantlar, rezonans frekans analizi ABSTRACT Evaluating the effect of design and length of implants on primary stability using resonance frequency analysis: An in vitro study Background: Primary stability (PS) is dependent on the length and diameter of the implant, micro-morphology of the implant surface, implant design, surgical procedure, bone quantity, and quality. This study aimed to compare short and standard dental implants according to primary stability in bone type IV using Resonance frequency analysis (RFA) test equipment. Methods: Seventy two dental implants; sandblasting with large grit particles and acid etching (SLA) surface (Dentium ® ,SimpleLine II, Seoul, Korea), SLActive surface-(Straumann Roxolid ® , Basel, Switzerland), Resorbable blast media (RBM) surface-(Implance ® , Trabzon, Turkey) with very short (4-mm length), short (6-mm length) and standard dental implants (10-mm length) were placed in bovine cow ribs with bone quality similar to a type IV human bone. RFA was performed to evaluate the primary stability. One-way ANOVA test was used to compare the groups ve different group...
