    A Comparison of Titanium and Resorbable Miniplate Systems Using Finite ElementAnalyses with the Orthotropic Mandibular Model in Condyle Fracture
    (2021) Önder, Mustafa Ercüment; Çimen, Emre; Cambazoğlu, Mine
    Background: Mandibular fractures comprise a large portion offacial injuries. According to comprehensive series published,17.5 - 52% of mandibular fractures are condyle fractures. Withthe development of plate and screw systems, open reductionand internal rigid fixation have also become methods that areaccepted. Titanium miniplate and screw systems or resorbableplate and screw systems are used for this purpose. Thepurpose of this study is to compare the superiorities of titaniumplate and screw systems to the superiorities of resorbable plateand screw systems on an orthotropic mandibular model usingthe finite element analysis (FEA) method. Methods: With finite element analysis, stress values in bone,plate and callus and the amount of displacement in plates andfragments with Von Mises forces were examined. Results: It was observed that solitary resorbable plates do notgenerate adequate stability. Conclusion: It was observed that titanium plate and screwsystems were mechanically superior to resorbable plate and screw systems in the open treatment of mandibular condylefractures. However, to fully support this opinion, studies withdifferent designs using new resorbable plates are required.

    KNOWLEDGE, ATTITUDES AND PERCEPTIONS OF DENTISTRY PATIENTS AND THEIR RELATIVES ABOUT THE COVID-19 PANDEMIC
    (2021) Erkan, Gözde Nur; Özgül, Özkan; Önder, Mustafa Ercüment
    Objective: The purpose of this cross-sectional survey was to investigate the attitudes, perceptions, awareness, and knowledge of dental patients and their relatives through concrete questions about behavior and prediction patterns among the Coronavirus Disease 2019 (COVID-19) pandemic.Material and Methods: The questionnaire was administered face-to-face to 292 patients and their relatives who applied to the dental hospital during the COVID-19 pandemic. The data were run through univariate and multivariable regression analyses. Survey variables include demographics, comorbidities, compliance with protective measures, prediction of disease severity in case of coronavirus infection, hospital admission behaviors, the presence of coronavirus infection in the relative and the severity of the disease experienced by the relative and the risk of transmission in dentistry interventions during the pandemic.Results: Participants showed high compliance with the use of masks in the proper area (77.4%). Generally, women's attitudes, knowledge, and perception levels were higher than men during the pandemic. Participants in the elderly age group (55-85 years) and with comorbidities predicted that they would get more seriously ill in case of coronavirus infection, but their knowledge, awareness, attitudes, and perception levels were lower than younger age groups. It was revealed that the knowledge, attitudes, and perceptions of the participants with low education levels and existing comorbidities were lower in general than high educated and non-comorbid participants.Conclusion: In order to ensure full compliance with the protective measures, awareness and informative campaigns should primarily aim to inform male, low educated, comorbid, and elderly individuals.

    Mandibulanın kondil ve ramus uzunlukları temporomandibular eklem düzensizliklerinde(TMD) predizpozan faktörler midir? Panoramik radyografi çalışması
    (2018) Önder, Mustafa Ercüment; Gürses, Gökhan; Tüz, Hakan Hıfzı; Atıl, Fethi; Tekin, Umut Saracoğlu
    Amaç: Temporomandibular eklem düzensizlikleri (TMD) oral ve maksillofasiyal bölgede sıklıkla karşılaşılanproblemlerdendir. TMD’nin meydana gelmesi ile ilgili pek çok teori mevcuttur. Anatomik koşulların da hastalığın etiyolojiksebeplerinden olabileceği düşünülmektedir. Bu çalışmada, TMD semptomu olan ve herhangi bir TMD semptomugöstermeyen hastalarda mandibular kondil, ramus uzunlukları ve birbirlerine olan oranları ölçülerek, etiyolojik faktörolarak değerlendirilip değerlendirilemeyeceği araştırmak amaçlanmıştır.Gereç ve Yöntemler: Çalışma kliniğimize başvuran yaşları 15–60 arası 59 hasta (n=40; semptomatik, n=19; asemptomatik)üzerinde yapılmıştır. Semptomlu hastalar her iki tarafta (bilateral) temporomandibuler bölgede krepitasyon, kliking ve ağrışikâyetlerinden en az biri için kliniğimize başvuran hastalar arasından seçilmiştir. Kontrol grubunda yer alan hastalar isetemporomandibuler eklem bölgesinde herhangi bir şikâyeti olmayan semptomsuz hastalar arasından seçilmiştir. Ramusve kondil uzunlukları standart panaromik radyografiler üzerinden değerlendirilmiştir.Sonuç: Her iki grup arasında yapılan değerlendirmeler sonucunda TMD olan hastaların kondil ve ramus boyu uzunluklarınınTME bölgesinde şikayeti olmayan hastalara göre daha uzun olduğu istatistiksel olarak tespit edilmiştir. Ancak kondil/ramusoranları arasında istatistiksel olarak anlamlı bir fark bulunmamıştır.Sonuç: Kondil ve ramus uzunluklarının TMD olan hastalarda daha uzun olduğu, etiyolojik faktör olarak belirtilebileceği söylenebilir.
