    Does the Endodontic Education Level Affect Decision-Making for Endodontically Treated Teeth With Apical Periodontitis? A Web-Based Survey

    Objectives: The management of endodontically treated teeth with apical periodontitis is debated among clinicians. The aim of this study was to evaluate treatment choices for endodontically treated teeth with different sizes of periapical lesions among endodontists, endodontics postgraduate students, general dental practitioners, and undergraduate students who had fulfilled their theoretical and clinical training in endodontics. Materials and methods: Periapical lesion images (no periapical lesion and 1-mm, 3-mm, and 5-mm periapical lesions) were formed on 4 different radiographs with a software program, and the survey included 16 radiographs that were emailed to 1881 participants. Treatment options included extraction, surgical or nonsurgical retreatment, and wait and see. The χ2 test was used to compare the responses of the participants. Results: The survey was returned by 1039 participants (55.23%). There were statistically significant differences among the responses of all participants for all cases (P < .05), except a case with a broken file and no lesion (P = .918). All participants decided to extract at an increased size from a 1-mm periapical lesion to a 5-mm periapical lesion. At all lesion sizes, general dental practitioners planned retreatment less when compared with other groups. Conclusions: This survey study showed that there was a positive correlation between endodontic education level and retreatment decision-making. Dentists who confront seemingly hopeless endodontically treated teeth such as an instrument fracture, a missing canal, or a large periapical lesion should consult with an endodontist before making the decision to extract the tooth.

    Compressive strength, surface roughness, and surface microhardness of principle tricalcium silicate-based endodontic cements after universal adhesive application
    (2022-03-01T00:00:00Z) Olcay, K; Guneser, MEHMET BURAK; Dincer, A N; Uyan, H M; GÜNEŞER, MEHMET BURAK
    Aims and background: It was aimed to evaluate compressive strength (CS), surface roughness, and microhardness of mineral trioxide aggregate (ProRoot MTA) and Biodentine (BD) after adhesive application. Materials and methods: Tests was carried out according to international ISO standard. ProRoot MTA and BD were prepared in Teflon molds according to manufacturer's instructions: n = 210 for CS; n = 210 for microhardness. Samples were incubated for 7 days at 37°C in 100% humidity. Surfaces were smoothed with up to 2000 grits of silicon-carbide sandpaper on abrasive device at 150 rpm, randomly divided into seven groups (n = 15). Clearfil Universal Bond, All Bond Universal, and Single Bond Universal (SBU) were applied in both total-etch and self-etch (SE) modes. Adhesives were applied according to manufacturers' recommendations (no adhesive used in control). CS was performed at speed of 1 mm/min, microhardness at 100 gr for 15 s. The surface roughness of the samples was analyzed with atomic force microscopy. Two-way analysis of variance and post hoc Tukey tests were used for the evaluation of the data. Results: Man CS and microhardness values between ProRoot MTA and BD were as follows: 24.9 N, 72.6 HV; 59.8 N, 59.0 HV, respectively. In CS, BD was higher than ProRoot MTA (P < 0.05). In other comparisons except for SBU SE group (P < 0.05), BD and ProRoot MTA showed similar results (P > 0.05). However, ProRoot MTA was found higher than BD regarding microhardness (P < 0.05). As a result of the adhesive application in both BD and ProRoot MTA groups, a decrease in surface roughness was observed compared to the control group. Conclusion: BD exhibited better results than ProRoot MTA regarding CS. However, ProRoot MTA was found to be more successful than BD in terms of microhardness. BD and ProRoot MTA showed similar physical properties in terms of surface roughness. To improve regenerative procedures, besides the selection of bioceramic cements, the interaction between cements and materials applied during coronal restoration should be considered.

    Micro-CT analysis of the marginal adaptation and porosity associated with ultrasonic activation of coronally placed tricalcium silicate-based cements
    (2020-08-01T00:00:00Z) DİNÇER, Asiye Nur; GÜNEŞER, MEHMET BURAK; Sisli, Selen Nihal; DİNÇER, ASİYE NUR; GÜNEŞER, MEHMET BURAK
    This study aimed to evaluate the effect of ultrasonic activation on coronal marginal adaptation and microporosity of tricalcium silicate-based materials. Sixty freshly extracted human maxillary lateral incisor teeth were instrumented with ProTaper Next X2 files followed by Peeso-Reamer burs, sizes 1 to 5. The specimens were randomly divided into six groups (n = 10): Group 1, Biodentine + hand condensation; Group 2, Biodentine + ultrasonic activation; Group 3, NeoMTA Plus + hand condensation; Group 4, NeoMTA Plus + ultrasonic activation; Group 5, ProRoot WMTA + hand condensation; and Group 6, ProRoot WMTA + ultrasonic activation. All tested materials were mixed mechanically and placed 2 mm underneath the cement-enamel junction by hand condensation or indirect ultrasonic activation. Volumetric analysis of the voids between the dentine wall and coronal barrier material and the porosity within the material was evaluated with micro-CT. There was no significant difference in marginal adaptation among the six groups (P > 0.05). Ultrasonic activation favoured a reduced microporosity in Biodentine Group (P < 0.001).

    Diş Hekimliği Öğrencilerinin Rubber-Dam Kullanımına Bakış Açısı ve Covid-19 Pandemisinin Etkisi: Anket Çalışması
    (2022-09-09) Nalcı G.; Balkancı B.; Uysal B. A.; Güneşer M. B.; Şahin A. N.; NALCI, GAMZE; GÜNEŞER, MEHMET BURAK
    AMAÇ: Bu çalışmanın amacı diş hekimliği fakültesi öğrencilerinin rubber-dam kullanımına bakış açısını tespit etmek, tercih etme veya etmeme sebeplerini ve COVID-19 pandemisinin etkisini araştırmaktır. GEREÇ VE YÖNTEM: Türkiye’nin çeşitli şehirlerindeki 944 diş hekimliği fakültesi dördüncü ve beşinci sınıf öğrencisine e-posta ve internet aracılığıyla 22 sorudan oluşan anket gönderildi. Çalışmaya yalnızca anketi tamamlayan katılımcılar dahil edildi. Açıklayıcı istatistiklere ek olarak yöntemlerin karşılaştırılmasında ki-kare testi kullanıldı. Sonuçlar anlamlılık düzeyinde değerlendirildi (𝑃 <0.05). BULGULAR: 370’i (%67.9) kadın, 175’i (%32.1) erkek olmak üzere 545 öğrenci anketi tamamladı. Katılımcıların %25.1’i daha önce hiç rubber-dam kullanmamış ve %41.8’i rubber-dam kullanımıyla ilgili tatmin edici bir eğitim almadığını belirtmiştir. Endodontik tedavi yaptığı her hastada rubber-dam kullanan katılımcı oranı ise %34.5’tir. Katılımcıların %87’si rubber-damın kök kanallarına erişimi kolaylaştırdığını, ancak %88,8’i rubber-damın radyograf alma prosedürünü zorlaştırdığını belirtmektedir. Öğrencilerin %69.2’si rubber-damın bulaş riskini azaltabileceğini düşünmüş ve %68.6’sında rubber-dam kullanma isteğinde artış olmuştur. SONUÇ: Öğrencilerin rubber-dam kullanımına karşı güncel bakış açılarını tespit etmek, eğitim içeriğine yön vermede faydalı olabilir. COVID-19 pandemisi gibi diğer tüm bulaşıcı hastalıklarla mücadelede öğrencilerin rubberdam bilgisinin ve yetkinliğinin artırılması önem taşımaktadır.
