Evaluation of Knowledge Levels of Dentistry Students on the COVID-19 and its Effects on Depression

Objective: To determine the level of knowledge of dentistry students regarding the COVID-19 outbreak and to evaluate whether the risk factors of the outbreak cause depression. Material and Methods: This study was conducted with 516 dentistry students (3rd, 4th and 5th grades) who started clinical practice in their education. The first part of the questionnaires applied to the students includes questions about demographic information, while the second part contains questions to determine their knowledge levels on the COVID-19 pandemic and protection against it.  In the third section, Beck Depression Inventory (BDI) was used to examine depression symptoms. The data were analyzed by frequency analyses and Chi-squared tests via the IBM SPSS 22.0 software. Results: Of the 516 students, 150 (29%) participants were in the 3rd, 212 (41%) were in the 4th and 154 (30%) were in the 5th grade. 355 (69%) students stated that their knowledge level about COVID-19 was high. 30.9% were conscious of the importance of using masks. 29.6% were aware of the importance of using gloves, 30.3% of not shaking hands. According to BDI scores, 37.1% of the participants seemed to experience moderate to severe and very severe depression. Conclusion: It was observed that the students didn’t have a sufficient level of knowledge about the factors affecting the spread of the pandemic. New stress factors such as COVID-19 may increase the incidence of depression

The relationship between hepatitis B virus infection and HLA phenotype

Bu çalışmada, HBV'ne bağlı hepatitin iyileşmesinde veya kronikleşmesinde, immüniteyi kontrol eden ve genetik geçişe göre insanlarda fark gösteren HLA doku gruplarının rolü olup olmadığı araştırıldı. Çalışmaya klinik, serolojik, biyokimyasal ve histopatolojik olarak HBV'na bağlı kronik aktif hepatit ve karaciğer sirozu tanısı konmuş 72 olgu; klinik, serolojik, biyokimyasal tetkikler sonucu asemptomatik HBsAg taşıyıcılığı saptanan 33 olgu ile serolojik testlerle bağışık olduğu tespit edilen 47 olgu alındı. Kontrol grubu HBsAg negatif, herhangi bir karaciğer hastalığı olmayan 62 olgudan oluşuyordu. Olguların HLA doku grupları standart mikrolenfositotoksisite testi ile çalışıldı. Sonuçlar, istatistiksel olarak p anlamlılık değeri hesaplanarak yorumlandı. Asemptomatik taşıyıcı olgularda HLA-A3 ve HLA-B14 görülme sıklığı artmış, HLA-B7 sıklığı azalmış bulundu

Authors’ response

Thank you, dear authors, for your questions. This study aimed to evaluate the videos on YouTube about early orthodontic treatment. It is stated in the article that there are different social media tools, but the article was prepared in the field of YouTube. It has been predicted that this is because the YouTube video-sharing platform has been evaluated more in studies among existing popular platforms.1, &nbsp;2, &nbsp;3 Exclusion criteria were determined with reference to previously published studies using a similar method.1, &nbsp;2, &nbsp;3, &nbsp;4 In the study, only the videos in the English language were evaluated. As stated in the discussion section, such an evaluation has been made because it is one of the most spoken languages in the world.4,5 Because our research topic is a certain treatment method, videos of different treatment methods were not evaluated to avoid confusion. In the study of Al-Silwadi et al,6 videos that do not contain any sound elements are excluded because it is recommended to use YouTube as an audio-visual instead of verbal and written notifications in orthodontic patients. In addition, it has been deemed appropriate not to include videos with advertisements and television shows as they may manipulate viewers and include biased content.2</p

Evaluation of oral health-related quality of life following dental rehabilitation under general anesthesia in Turkish children with early childhood caries

Background: Early childhood caries (ECC) is one of the most common dental problems, which often require dental rehabilitation with general anesthesia (DRGA). Aim: To assess the short- and long-term effects of DRGA on children and their families' oral health-related quality of life (OHRQoL) in preschool children, the incidence of complications on the first day, and the factors affecting them and parental satisfaction. Design: A total of 150 children treated for ECC under DRGA were included in the study. OHRQoL was assessed on the day of DRGA, 4 weeks, and 1 year after treatment using the Early Childhood Oral Health Impact Scale (ECOHIS). The incidence of complications and parental satisfaction with DRGA were evaluated. The data were analyzed for statistical significance (p <.05). Results: In total, 134 patients were re-evaluated at the end of the fourth week and 120 at the end of the first year. The average ECOHIS scores before and after DRGA (4 weeks and 1 year) were 18.1 ± 8.5, 3.1 ± 3.9, and 5.9 ± 6.2, respectively. After DRGA, 29.2% of the children reported at least one complication. Ninety-one percent of the parents reported that they were satisfied with DRGA. Conclusion: DRGA has a positive effect on the OHRQoL of Turkish preschool children with ECC and is highly evaluated by their parents

YouTube as an information and education source for early orthodontic treatment

Introduction: This study aimed to evaluate the content, reliability, and quality of YouTube videos for early orthodontic treatment. Methods: YouTube video searches were carried out using the keyword “early orthodontic treatment,” which was determined using Google Trends. After sorting according to relevance, the first 120 &nbsp;videos were observed, and 61 videos were analyzed accordingly. Further, the general characteristics, &nbsp;uploader source, reliability score (RS), global quality scale (GQS), video information quality index, &nbsp;audiovisual quality, viewers’ interaction index, viewing rate, and total information content score (TCS) data belonging to these videos were analyzed. Based on their reliability scores, videos were divided into 2 main groups (low and medium/high information content) accordingly. Results: It was found that 25 (41%) of the videos had medium/high information content, and 36 (59%) had low information content, respectively. Videos with medium/high information content were found to have long video durations, increased comments, and high TCS, &nbsp;GQS, RS, and video information quality index scores (P\0.05). The videos uploaded by doctors had increased comments, long duration, and high TCS, GQS, and RS scores (P \0.05). Conclusions: The quality of the information provided by YouTube videos on early orthodontic treatment was generally insufficient. In addition, &nbsp;the information quality was high for videos uploaded by doctors.&nbsp;</p
