    Effect of sodium ascorbate and delayed treatment on the shear bond strength of composite resin to enamel following bleaching
    (WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2016) TÜRKMEN, CAFER; Turkmen, C.; Guleryuz, N.; Atali, P. Y.
    Background: The effect of bleaching on enamel surfaces, as well as exploring methods of preventing the weakening of bond strength of two different adhesives to bleached enamel surfaces. Objective: This study compared the shear bond strength (SBS) of two different adhesives on bleached enamel immediately after bleaching, with a 1-week delay, and following application of an antioxidizing agent after bleaching. Materilas and Method: The enamel surfaces of 140 incisors were divided into 14 groups. Two unbleached enamel groups (n = 20) were prepared as negative controls of the Adper Single Bond 2 total-etch and Clearfil Tri S Bond self-etch adhesives. The remaining surfaces were randomly divided into two bleaching groups treated with 35% Beyond Max (n = 60) and 38% Opalescence Xtra Boost (n = 60). Each bleaching group was then divided into two subgroups using the total and self-etch adhesive systems. Specimens were bonded immediately after bleaching, after treatment with 10% sodium ascorbate (SA) gel, or after 1-week of immersion in artificial saliva. All groups were restored with composite resin. After thermocycling, SBS was measured and data were analyzed. Results: In the control groups, there was no statistically-significant difference in SBS between self-and total-etch adhesives. Among all bleaching groups, no statistically-significant differences in SBS were noted, although the SA-treated delayed bonding (1-week) groups had the highest values. The lowest values were noted for the groups bonded immediately after bleaching.

    (2021-07) KORKUT, BORA; Bayraktar, Ezgi T.; Atali, Pinar Y.; Korkut, Bora; Kesimli, Ezgi G.; Tarcin, Bilge; Turkmen, Cafer
    Abstract Objectives This study was aimed to determine the effects of modeling resins on the surface microhardness of composites. Materials and Methods Six resin-based composites (Charisma Smart, Estellite Asteria, CeramX-One SphereTEC, Admira Fusion, Filtek Ultimate, and Clearfil Majesty Es-2) and three wetting agents (Modeling Liquid, Composite Primer, and Modeling Resin) were investigated. In all, 240 specimens were prepared, and wetting agents were applied prior to light curing in the experimental groups. After 24 hours, specimens were polished and Vickers microhardness (VHN) values were measured. Statistical Analysis Shapiro–Wilk and two-way analysis of variance (ANOVA) were used for analyses (p < 0.05). Results Both modeling resin and composites were determined to be effective factors (p < 0.001). The control group showed the highest VHN (70.37 ± 7.94), followed by Modeling Liquid (64.68 ± 12.07), Composite Primer (59.84 ± 6.33), and Modeling Resin (58 ± 3.52b; p < 0.001). Filtek Ultimate showed the highest VHN (76.62 ± 9.78c), whereas Charisma Smart (58.87 ± 7.95), and Clearfil Majesty (67.27 ± 2.58) showed the lowest (p < 0.001). Clearfil Majesty–Modeling Liquid (46.62 ± 5.33) and Charisma Smart–Composite Primer (50.81 ± 0.39) combinations showed the lowest VHN, whereas Filtek Ultimate–control (87.15 ± 2.12) and Filtek Ultimate–Modeling Liquid (84.24 ± 3.11) showed the highest (p < 0.001). Conclusion All tested modeling resins decreased VHN value, and the amount of reduction varied among composites and wetting agents. It might be safer not to use wetting agents unless they are necessary.

    (2023-07-03) MANAV, AYBİKE; DOĞU, BENGÜ; YILMAZ ATALI, PINAR; KAHRAMANOĞLU, ERKUT; ŞENOL, AYŞE ASLI; TARÇIN, BİLGE; TÜRKMEN, CAFER; MANAV ÖZEN A., DOĞU KAYA B., YILMAZ ATALI P., KAHRAMANOĞLU E., ŞENOL A. A., TARÇIN B., TÜRKMEN C.
    Introduction: The aim of this in vitro study was to evaluate the fracture resistance of sonic-activated SonicFill3 (SF) (Kerr) and flowable Charisma Bulk Flow ONE (CO) (Kulzer) bulk-fill composites with or without polyethylene-fiber (R) (Ribbond) application. Materials and Methods: Class I cavities (2x2x4mm) were prepared on 40 freshly extracted human premolars of similar size and classified randomly into 4 groups (SF, SF+R, CO, CO+R). The remaining wall thicknesses of the teeth was confirmed to be 2mm. Ribbond fiber (2x2mm) was applied to cavity bases of the acryl-embedded teeth according to manufacturers’ instructions and OptiBond (Kerr) (for SF, SF+R groups) and Gluma Bond (Kulzer) (for CO, CO+R groups) universal adhesives were used. All specimens were restored in a 4mm monolayer with SF and CO. Valo Cordless (Ultradent) LED-curing unit with a power output of 1000 mW/cm2 was preferred for polymerization. Finishing and polishing were completed with the last 2 stages of Sof-Lex discs (Kerr). Restored teeth were stored in distilled water at 37°C for 24 hours. Fracture resistance (FS) and elastic modulus (EM) values were measured with a universal testing device (Shimadzu AG-X, Shimadzu Corp, Japan). Data were analyzed with IBM SPSS V23 using Independent samples T-test. The significance level was set at p<0.05. Results: No statistically significant difference was found between the bulk-fill composites (SF and CO) without R (p=0.167). Similarly, no significant difference was detected between the Ribbond fiber applied groups (SF+R and CO+R) (p=0.994). The effect of fiber application on FS of SF (p=0.421) and CO (p=0.552) was not statistically significant. The mean maximum force values (newtons) in decreasing order were CO (761.09±224.32) > SF+R (671.08±150.51) > CO+R (669.95±358.44) > SF (580.7±269.04). The EM values of SF and CO were statistically significantly different (p=0.009). A statistically significant difference was observed between the EM values in the Ribbond fiber applied groups (SF+R and CO+R) (p=0.026). EM values of CO were statistically significantly higher regardless of Ribbond application (p<0.001). Conclusion: Within the limitations of this in vitro study, the application of SonicFill3 and Charisma Bulk Flow ONE composites with Ribbond may be an option for clinical applications.

    (2022-04-23) ŞENOL, AYŞE ASLI; KAHRAMANOĞLU, ERKUT; YILMAZ ATALI, PINAR; TÜRKMEN, CAFER; Altuntaş E., Öztürk S., Şenol A. A., Kahramanoğlu E., Yılmaz Atalı P., Türkmen C.
    Molar incisor hypomineralization (MIH) is an enamel defect that develops in the molar and incisors as a result of exposure of ameloblast cells to various environmental and systemic factors during the maturation phase of amelogenesis, thus causing aesthetic concerns. In this case report microabrasion and home bleaching was planned for the treatment of MIH.A 17 years old female patient who referred to our clinic with the chief complaint of white lesions on maxillary incisor teeth, were examined clinical and radiographically In both the maxillary and mandibular arch, visible opacities were detected and microabrasion and home bleaching techniques were planned for the treatment of lesions. Before microabrasion application, Tooth Mousse Gel (GC) was applied on the lesions for two weeks. Shade selection was performed by spectraphotometer (Vita EasyShade V). Under the rubber dam isolation (maxillary-arch) and gingival barrier (mandibullary-arch) Opalustre (Ultradent) was applied in 3 consecutive cycles using OpalCups (Ultradent) according to manufacturer’s guidelines. Fluoride varnish (4% NAF, ProShield, President Dental) was applied for 4 minutes following the microabrasion. Home bleaching gel was applied for 5 weeks with custom made bleaching tray using 16% Carbamide Peroxide (Opalescence PF, Ultradent) Patient were recalled for 7,14,21,28 and 35 day. For the examination of the lesions and color of teeth.The using of ACP-CPP containing gel before the treatment, made a difference in the visibility of enamel hypomineralizations. The shades of incisor teeth which, was the patient’s complaint was B3 initially A2 after microbrasion and A1 after bleaching. The patient was satisfied with the treatment results.Application of remineralisation gel for two weeks, reduced the size of enamel hypomineralizations.The combined use of microabrasion and home bleaching is more effective in reducing lesions, eliminating aesthetic concerns and provided a more comfortable treatment process for the patient with MIH.

    Riboflavin ve Kalsiyum Gliserofosfat Kombinasyonunun Dentin Remineralizasyonuna Etkisinin Optik Koherens Tomografi ile İncelenmesiPelin Kükey1, Pınar Yılmaz Atalı1, Ezgi Altuntaş1, Cafer Türkmen1 and Betül Kargül21Restoratif Diş Tedavisi Anabilim Dalı, Marmara Üniversitesi, Istanbul, Türkiye2Pedodonti Anabilim Dalı, Marmara Üniversitesi, Istanbul, TürkiyeAmaç: Optik Koherens Tomografi (OCT) noninvaziv, yüksek çözünürlüklü, kesitsel bir görüntüleme tekniğidir. Bu çalışmanın temel amacı, yüksek çözünürlüklü (HD) spektral alanlı optik koherens tomografi (SD-OCT) kullanarak CaGP içeren diş macunu ve %2’lik Riboflavin solüsyonunun yapay dentin çürüğü lezyonları üzerindeki etkinliğini göstermektir.Yöntem: 16 adet insan molar dişi kullanılarak hazırlanan dentin örnekleri 72 saat demineralizasyon solüsyonunda bekletildi ve rastgele 4 gruba ayrıldı: Grup 1: CaGP + magnezyum klorür (MgCl2) + %10 ksilitol içeren diş macunu uygulanmış yüzeyler; (R.O.C.S Hassas Onarım ve Beyazlatma DRC Group Moskova, Rusya); Grup 2: CaGP, ardından %2 Riboflavin Solüsyonu; Grup 3: %2 Riboflavin Solüsyonu, Grup 4: deiyonize su. Dentin yüzeylerinin uygulama yapılmış bölgelerinde OCT görüntülemesi yapıldı. Remineralizasyon derinliği ve remineralizasyon tabakasının kalınlığı, tüm gruplardaki örnekler için ayrı ayrı hesaplandı.Verilerin normallik dağılımının değerlendirilmesi Shapiro Wilk testi kullanılarak doğrulandı. İki bağımlı grubu karşılaştırmak için normal veriler için Paired t testi kullanıldı. (p<0,05)Bulgular: Tedavi içeren tüm gruplardaki dentin örneklerinde optik lezyon derinliğini azalmıştır. Grup 1 ve Grup 2 içeriğindeki örneklerin yüzeylerinde remineralize alan kapasitelerinin arttığı ve optik lezyon derinliklerinin genel olarak azaldığı saptanmıştır. Lezyon derinliğindeki azalma miktarı açısından fark; Grup 2’de, Grup 1, 3 ve 4\"teki farklılıklardan anlamlı derecede yüksekti (p<0,05). %2 Riboflavin içeren CaGP içeren diş macunu kombinasyonu, test edilen gruplar arasında en yüksek remineralizasyon etkisini gösterdi.Sonuç: Bu sonuçlara dayanarak ve mevcut deneysel koşullar altında, Riboflavin ile CaGP kombinasyonunun, dentin remineralizasyonunu teşvik ederken dentin demineralizasyonunu inhibe ettiği ve sinerjik etki gösterdikleri sonucuna varılmıştır.Anahtar Kelimeler: Kalsiyum gliserofosfat, Optik Koherens Tomografi, Biyomimetik mineralizasyon, Riboflavin, Magnezyum Klorür
