Background Coronavirus disease (COVID-19) was first reported on 31 December 2019 and has rapidly been spreading day by day. Dental patients and professionals have a high risk of the coronavirus infection and also have a huge responsibility to prevent its spread during emergency dental treatment over the period of the COVID-19 outbreak. Aim Informing patients and dental practitioners about the novel coronavirus in an accurate and effective way is very important. Therefore, this study aimed to evaluate the quality of dentistry-related medical information about COVID-19 on YouTube as educational resources for dental practitioners. Methods YouTube was queried for the search phrases 'COVID-19 and dental practice', 'SARS-Cov-2 and dental practice' and '2019-COV-2 and dental practice'. The first 100 videos for each term were viewed and analysed by 3 independent investigators. The scope was limited to videos in English. Results The search phrases yielded 1102 videos, among which 802 videos were excluded and 300 videos screened. Fifty-five videos were included in the final analysis. Of the 55 videos, only 2 videos (3.6%) were found to be of good quality, while 24 videos (43.6%) were found to be of poor quality. Conclusion YouTube is a popular video broadcast site and can provide both relevant educational information and the spreading of misinformation. Health professionals should play a more active role with regard to educative information given on social media, especially YouTube, during global disease outbreaks.

Aim: To evaluate the effect on vertical bone augmentation of the screw tent-pole technique using particulate allograft in combination with injectable platelet-rich fibrin, and to compare this with autogenous block bone graft. Materials and Methods: This split-mouth randomized controlled study involved patients with bilateral partial edentulism and vertical bone loss in the posterior mandible. In each patient, the control side was treated with autogenous block bone graft harvested from the mandibular ramus and, on the test side, the screw tent-pole technique was employed, using particulate allograft in combination with injectable platelet-rich fibrin. All augmented sites were covered by leukocyte and platelet-rich fibrin membrane. The primary outcome variable of this study was the radiographic changes to bone height 6 months after augmentation. The secondary outcome variables were the percentage of newly formed bone and the implant survival rate. The data were analyzed with a significance level of α = 0.05. Results: Of the 13 patients included, a total of 11 patients (7 females, 4 males; mean age 50.92) completed the study. The mean values of vertical bone gain were 1.72 ± 0.78 mm for the test group and 2.83 ± 0.89 mm for the control group, which constitutes a significant difference ( P = .008). The percentage of newly formed bone was 18.08% ± 2.17% for the test group and 14.26% ± 1.76% for the control group. The difference between the groups was statistically significant ( P < .001). The implant survival rates were 100% for both study groups. Conclusions: Based on the study results, screw tent-pole can be considered a feasible technique for bone augmentation. Further randomized studies will be necessary to fully evaluate vertical bone augmentation using the screw tent-pole technique, with different graft materials and with larger samples.

Background: The aim of this prospective study was to assess the effectiveness of concentrated growth factors (CGF) in preventing the development of alveolar osteitis (AO) after the extraction of partially-erupted mandibular third molars. Methods: Seventy patients (26 men and 44 women) 18 years or older (mean age 25.86; range 18-35) underwent 140 third molar extractions. All the patients presented with bilateral, partially-erupted mandibular third molars and underwent surgical extractions. In each case, one socket received CGF and the other served as a control. The predictor variable was the CGF application and the sides were categorized as 'CGF' and 'non-CGF'. The outcome variable was the development of AO during the first postoperative week. Other study variables included age and gender. Data were analyzed using Cochran's Q test with the significance level set at a P value less than 0.05. Results: The overall frequency of AO was 11.4% for the control group. The frequency of AO in the CGF group was significantly lower than in the non-CGF group (p < 0.001). Conclusions: Based on the results of this study, application of CGF fibrin gel may decrease the risk of AO development after mandibular third molar surgery. Trial registration: This study was registered in ClinicalTrials.gov database on November 1, 2019 (ID: NCT04151147, retrospectively registered).
