Amaç: Bruksizm ile ilgili bilgi kaynağı olarak YouTube™ videolarının içeriğinin ve kalitelerinin değerlendirilmesidir. Gereç ve Yöntem: YouTube™ videolarında “diş sıkma, bruksizm” kelimeleri ile Türkçe videolarda arama yapıldı ve ilk sırada yer alan videoların URL’leri kaydedilerek iki araştırmacı tarafından tüm videolar incelendi. Videolara ait tanımlayıcı istatistikler kaydedildi ve verilerin minimum, maksimum, ortalama, standart sapması hesaplandı. Elde edilen değerler, istatistiksel olarak incelendi ve sürekli değişkenler Kruskal-Wallis testi ile analiz edildi (p<0.05). Bulgular: Toplam 250 video değerlendirmeye alındı. Bu videolardan değerlendirme kriterlerine uyan 68 video çalışmaya dahil edildi. Değerlendirmeyi yapan iki gözlemci arasında istatistiksel olarak anlamlı seviyede yeterli uyum vardı (Kappa=0.754, p0.05). Sonuç: Bruksizm ile ilgili YouTube™’da yer alan videoların çoğu az yararlıdır. Alanında uzman hekimler ve akademisyenler, YouTube™’a daha yararlı ve bilgilendirici videolar ile katkı sağlayabilirler, bireylerin doğru bilgiye ulaşmasına ve toplum sağlığına faydalı olabilirler.

Aim The purpose of our study was to evaluate the antibacterial activities and dentin bond strengths of silver nanoparticles (Ag NPs) and silver nano-graphene oxide nanocomposites (Ag@nGO NCs) produced by green and chemical synthesis method added to dental adhesive. Methods Ag NPs were produced by green synthesis (B-Ag NPs) and chemical synthesis methods (C-Ag NPs) and deposited on nGO (nano-graphene oxide). Ag NPs and Ag@nGO NCs (0.05% w/w) were added to primer and bond (Clearfil SE Bond). Group 1: control, Group 2: nGO, Group 3: B-Ag NPs, Group 4: B-Ag@nGO NCs, Group 5: C-Ag NPs, Group 6: C-Ag@nGO NCs. S. Mutans live/dead assay analysis, MTT metabolic activity test, agar disc diffusion test, lactic acid production and colony forming units (CFUs) tests were performed. Bond strength values were determined by microtensile test. Failure types were determined by evaluating with SEM. Statistical analysis was performed using one-way ANOVA and two-way ANOVA (p < 0.05). Results There was a difference between the groups in the viable bacteria ratio and lactic acid production tests (p < 0.05). When the inhibition zone and S. Mutans CFUs were evaluated, there was no difference between Group 3 and Group 4 (p > 0.05), but there was a difference between the other groups (p < 0.05). When metabolic activity of S. Mutans was evaluated, there was a difference between Group 1 and other groups, and between Group 2 and Group 5 and Group 6 (p < 0.05). There was no difference between the groups in the microtensile bond strength values (p > 0.05). Conclusion Adhesives containing B-Ag NPs and B-Ag@nGO NCs provided sufficient antibacterial activity and did not reduce bond strength values. Clinical Significance: The addition of biocompatible B-Ag NPs and B-Ag@nGO NCs to the adhesive system increased the antibacterial effect by maintaining the bond strength of the adhesive. Antibacterial adhesives can increase the restoration life by protecting the tooth-adhesive interface.
