    Impact of a Surface Sealant Application on the Color Stability of a Nano-hybrid Composite Resin

    Objective: Mouthwashes containing chlorhexidine can cause discoloration in restorative materials when used for the long-term. To prevent staining of a restorative material, several protective materials are used. The aim of this in vitro study was to evaluate the impact of a surface sealant on the color stability of a nano-hybrid composite resin material immersed in different mouthwashes. Methods: A total of 42 composite resin discs (10x2 mm) were prepared with a nano-hybrid composite resin (Herculite XRV Ultra) using Teflon moulds. The composite specimens were first divided into two groups (with or without a surface sealant) then into three subgroups (n=7) according to the mouthwashes (Gengigel, Oderol, and Chlorhex). After SS application to 21 specimens, all the discs were subjected to baseline color measurements using a spectrophotometer according to the Commission Internationale de l’Eclairage L*a*b* system. The specimens underwent thermal cycling. Following immersion in different mouthwashes for 24 hours, the color measurements were repeated. The ∆E data were assessed using Kruskal-Wallis one-way ANOVA. Mann-Whitney U test was performed for different immersion mouthwashes (p<0.5). Results: Statistically significant differences (p<0.5) were found between the unsealed composite specimens immersed in Chlorhex and the other mouthwashes in terms of ∆E values. The Chlorhex appeared to be associated with the most severe alteration in color (5.14±0.83), followed by Gengigel (2.21±1.46) and Oderol (1.94±1.75). There were no statistically significant differences (p>0.05) between the sealed and unsealed composite specimens in terms of the color changes. Conclusion: The application of a low viscosity liquid surface sealant material did not show the expected effect on the color stability of a nano-hybrid composite resin in terms of three different mouthwashes.

    Perceptions of dental students towards online education during the COVID-19 pandemic
    (2021-12-01T00:00:00Z) Sarıalioğlu Güngör, Ayça; Şeşen Uslu, Yeşim; SARIALİOĞLU GÜNGÖR, AYÇA; DÖNMEZ, NAZMİYE
    Purpose: This study evaluated the usage habits, attitudes, and perceptions of undergraduate dental students toward distance (online) learning and identified variables related to those attitudes. Materials and methods: The study included 1,605 undergraduate dental students who participated voluntarily. The data collection tool consisted of a distance learning attitude scale, a questionnaire on personal information, and open-ended questions. The perceptions of dental students to distance education according to the year and type of dental school they attended were evaluated. Results: Most students expressed that distance learning in dental courses was not as effective as traditional face-to-face education (59.1%, n=949). While students studying at state universities had a more negative view of distance education, the satisfaction scores of the first-year students were found to be significantly lower than the other students (p<0.05). Conclusion: Dental students were generally unhappy with the interruption of traditional education caused by COVID-19 and having to continue their education online. However, under the circumstances, they saw it as an advantage allowing them to continue their education and avoid a complete suspension.

    Girişimsel olmayan araştırmalarda, ilgili etik kurulun onayını almadan çalışmalara başlamak mümkün değildir. Dünya Sağlık Örgütü-nün kurallarına göre, gerekli tüm belgeleri içeren başvuru dosyası ilgili Etik Kurula eksiksiz sunulmalıdır. Araştırmacıların başvuru dosyasındaki belgeleri eksiksiz tamamlamadaki isteksizliği, Etik Kurulların çalışma sürecini yavaşlatmakta ve hatta Etik Kurul ile araştırmacılar arasında tartışmaya bile neden olabilmektedir. Bu nedenle bu çalışma, bir üniversitenin Girişimsel Olmayan Araştırmalar Etik Kuruluna gönderilen proje başvuru dosyalarındaki eksiklikleri ve en çok yapılan hataları göstermek ve araştırmacılar için bir rehber oluşturmak amacıyla yapıldı. 24 Mart 2016 ve 30 Haziran 2018 tarihleri arasında Girişimsel Olmayan Araştırmalar Etik Kurula gönderilen başvuru dosyaları ve kararları ilgili etik kurulun veri tabanından analiz edildi. Başvuru dosyalarının revizyonuna neden olan en önemli gerekçeler, projenin amacının ilgili referanslar eşliğinde yeterince açıklanamaması ve özellikle iyi yazılamamış yöntem kısmı gibi başvuru formundaki eksikliklerdi. Araştırmacıları proje başvuru dosyası hazırlarken en çok yapılan hatalar hakkında eğitmek, Üniversite Etik Kurullarının gözden geçirme sürecinin verimliliğini ve hızını artıracaktır.

    Knowledge, stress levels, and clinical practice modifications of Turkish dentists due to COVID-19: a survey study

    Dentists are exposed to the highest risk of occupational respiratory and droplet infections by working face-to-face with patients. The aim of this study was to investigate the knowledge of symptoms and modes of transmission of COVID-19, stress levels and clinical practice modifications of Turkish dentists during the COVID-19 pandemic. An online survey (15 questions) was sent to Turkish dentists from May 5 to 12 May, 2020. The survey comprised questions about dentists’ demographic characteristics, their knowledge about COVID-19, stress levels and the measures taken in dental clinics against COVID-19. This study included a total of 1,095 Turkish dentists. The data were expressed as frequency with percentage values for overall variables. Dentists were most familiar with high fever among the symptoms of COVID-19 (99.4%) and 99.2% of them reported that COVID-19 was transmitted with eye, mouth and nasal mucosa contact on surfaces contaminated with the droplets of infected persons. While the stress levels of females were higher than males, the stress levels of dentists with more than 20 years of professional experience were found to be lower. Regarding the precautions to be taken as a preventive measure when working again, 86.6% of the dentists took precautions by increasing daily patient care intervals and only 38.4% of the dentists wore an N95 mask. During this pandemic, knowing the conditions about when the treatments can be applied and the precautions to be taken will shed light on dentistry staff. Current recommendations of national authorities about the coronavirus should be followed.
