Örnekler, cila sonrası 3 aylık kahve tüketimine denk ge?lecek sürede (72 saat) kahve çözeltisinde renklendirilmiştir. Klinik tip _x000D_ spektrofotometre cihazı ile renklendirme öncesi/sonrası renkler ölçül?müş ve ∆E* değerleri hesaplanmıştır. Algılanabilirlik sınırı 3,7, kabul _x000D_ edilebilirlik sınırı 5,5 olarak alınmıştır. İki yönlü varyans analizi ile ba?ğımsız iki örnek t-testi istatistiksel analiz için kullanılmıştır. Bulgular:_x000D_ Yalnızca cila materyali değişkeni, ∆E* üzerine etkili faktör olarak bu?lunmuştur (p<0,001). En yüksek ∆E* Super Snap grubunda (3,37±1b), _x000D_ en düşük ise Twist Dia grubunda (1,54±0,77a) bulunmuştur. Nanohib?rit ve mikrohibrit kompozitler arasında, renklenme açısından anlamlı bir _x000D_ fark bulunmamıştır (p=0,055). Tüm kompozit-cila materyali kombinas?yonlarında, ∆E* kontrol grubuna göre anlamlı derecede düşük bulun?muş (p<0,001) ve algılanabilir sınırın altında (<3,7) kalmıştır. Sonuç:_x000D_ Bu çalışmanın şartları altında, aşındırıcı olarak elmas partikülü içeren, _x000D_ iki aşamalı, spiral cila sistemleri Twist Dia ve Soflex Spiral, kompozit _x000D_ yüzey cilalamasında, cilalama süresi ve renk değişimi bakımından, diğer _x000D_ cila materyallerine göre daha avantajlı ve etkili olarak değerlendirilebi?lir. Farklı kompozit materyaller ile destekleyici çalışmalar yapılmalıdır.Publication Metadata only Anteri̇or esteti̇kte rezi̇n kompozi̇t restorasyonlar(Quintessence Publishing Co, Inc., 2022-03-01) KORKUT, BORA; Korkut B.Publication Metadata only Comparison of caries removal techniques and dental scanners for quantitative volume-loss(2023-09-21) KANAR, ÖZLEM; TAĞTEKİN, DİLEK; KORKUT, BORA; KANAR Ö., TAĞTEKİN D., KORKUT B.Publication Metadata only The relation between laser fluorescence scores after caries removal and microtensile bond strength(2023-07-04) KANAR, ÖZLEM; TAĞTEKİN, DİLEK; KORKUT, BORA; KARGÜL, BETÜL; KANAR Ö., TAĞTEKİN D., KORKUT B., YANIKOĞLU F., KARGÜL B.Publication Metadata only Multı̇dı̇sı̇plı̇ner yaklaşımla oluşturulan estetı̇k gülüş tasarımı: Bı̇r olgu sunumu(2021-05-02) KORKUT, BORA; AĞRALI, ÖMER BİRKAN; GÜLER C., ÖZDEMİR F., KORKUT B., AĞRALI Ö.

This review discusses the strategies for restoring teeth with CTS and suggests a related clinical decision tree. Recent Findings CTS is the incomplete fracture of the natural tooth crown. Preparation type and direct/indirect restorative protocol choices are the important factors efecting the prognosis of the tooth while multi-factorial etiology, complexity in diagnosis, and subjective decisions about the preparation make the clinical management very difcult. Therefore, the clinical management of CTS should be carried out by the guidance of an informative decision tree. This decision tree should focus on (1) the rational retention of tooth structure, (2) the preparation optimization, and (3) the restorative implications and choices. Summary The restorative management of CTS is a complex issue which should be carried out systematically. The guidance of an informative, universal decision tree might be useful in daily clinical practice.Publication Open Access Two-year retrospective evaluation of monoshade universal composites in direct veneer and diastema closure restorations(2022-01-01) KORKUT, BORA; KORKUT B., Ünal T., Can E.© 2022 Wiley Periodicals LLC.Objectives: The aim of this retrospective evaluation was to assess the short-term outcome of two monoshade universal resin composites with high chameleon effect in anterior direct veneer and diastema closure restorations, and to investigate the possible reasons for failure. Material and Methods: Patients subjected to veneer and diastema closure restorations with two monoshade universal resin composites (Essentia Universal Shade; EU, GC Corp., and Omnichroma; OC, Tokuyama) operated between January 2018 and March 2019 were selected for the present retrospective evaluation. A total of 159 composite restorations (78 veneers and 81 diastema closure restorations) performed by a single operator in 44 patients (mean age: 33.6) were included in the study. Two blinded and calibrated examiners performed 1- and 2-year assessments of the restorations with respect to FDI criteria, using medical/clinical history and dental photography records. Data were analyzed using Pearson Chi-square with Continuity Correction, Fisher\"s Exact tests, and Cox regression (a < 0.05). Results: The cumulative overall survival rates of EU and OC restorations were 94.6% (97.3% for the first year) and 88.6% (95.3% for the first year), respectively, with no significant difference from each other (p = 0.316). The cumulative overall survival rates of direct veneer and diastema closure restoration types were 90.2% (95.1% for the first year) and 92.4% (97.4% for the first year), respectively, with no significant difference (p = 0.559). The reasons for failure were evaluated as fracture of the restoration, failure in esthetic anatomical form, and color mismatch. All the failed direct veneer restorations were due to fractures (FDI score of 5.4), whereas 5 of 6 failed diastema closure restorations were due to color mismatch (FDI score of 3.4). Regarding the composite materials, there were no significant differences between the success rates of the restoration types (p = 0.442 for EU, p = 1.000 for OC). With respect to the restoration types, there were also no significant differences between the success rates of the resin-based composites (p = 1.000 for direct veneer restorations and p = 0.228 for the diastema closure restorations). In addition, no significant difference was observed between male and female patients regarding the acceptable and unacceptable scores (p = 1.000). Conclusions: The 2-year clinical performance of the two monoshade universal composites in anterior veneer and diastema closure restorations were both considered successful and similar. Despite the lack of shade selection, both monoshade universal composites presented a successful color match. However, the diastema closure restorations might be more prone to color mismatch compared to the veneers over time, while veneer restorations presented more fractures than the diastema closure restorations. Clinical Significance: Monoshade universal composites presented successful short-term clinical outcomes regarding both function and esthetics in anterior direct veneer and diastema closure restorations.Publication Metadata only Polychromatic Reverse Layering Technique (PRLT) for Crown Fracture Restorations(2022-12-17) KORKUT, BORA; BİLGİN GÖÇMEN, GÜLÇİN; YILMAZ ATALI, PINAR; TARÇIN, BİLGE; Korkut B., Bilgin Göçmen G., Yilmaz Atali P., Tarçin B., Yanikoğlu F.
