“…Oliveira et al [32] showed that there are no significant differences between the level of shrinkage stress at the tooth-restoration interface when these two techniques of resin composite placement are used. However, Versluis et al [33] observed that the highest degree of cusp flexion occurs in the horizontal technique followed by the oblique one.…”

Do the new, modern dental resin composites improve the sealing in cavities restorations? The present study was designed to compare the effect of two different, but most used layering techniques of the dental composite in reducing the marginal microleakage when a brand-new material is used; Class I black cavities were prepared on 120 human extracted teeth and then restored using oblique and horizontal layering technique. The dye penetration analysis, the atomic force microscopy (AFM), scanning electron microscopy (SEM) together with energy-dispersive X-ray spectroscopy (EDX) and Fourier transform infra-red spectroscopy (FTIR) technique were used to assess the adaptation of the restorative material to the dental structures. Some better results were obtained for oblique layering technique, but the differences to the other method have not been statistically validated. The composite layering technique still remains an open quest and, moreover, in vivo studies should be designed in order to assess microleakage in real conditions of the oral environment.

“…Due to the shape of the layers, they cover less of the wall surfaces than in horizontal layering. This leads to less stress at the tooth/restoration interface [32].…”

“…Studies showed that layering techniques in resin composite restorations affected the microtensile bond strength between the resin composite and the dentin, and those horizontal and oblique techniques have shown differences in polymerization shrinkage stress patterns. [ 34 35 ] Finally, the majority of students do not perform extra curing after the removal of matrix band and retainer in class II restorations for at least 20 s although there is an increase in the degree of conversion of posterior composite restorations during the extra curing period.

Aim and Objective:This survey investigated bonding system type and composite application rationale by senior dental students at a dental school in Saudi Arabia.Materials and Methods:Eighty-three questionnaires with 15 open and closed questions were randomly distributed to final year dental students about the use of etch and rinse versus self-etch adhesives and application techniques for posterior resin composite. Data were collected, and statistical analysis was done using Chi-square test (0.05) with two factors “question answer” and “gender.”Results:For all questions, the impact of gender was statistically nonsignificant (P > 0.05). Etch and rinse adhesive was significantly (P > 0.05) favored by students with majority do not perform selective etching, use intermittent air for drying tooth structure, apply a single layer bonding agent and thin it by air, cure it for 20 s with the curing tip at close proximity to the cavity, use incremental application technique for composite restorations, cure it for 40 s, and neglect to do extra curing.Conclusion:Students showed good knowledge regarding the bonding and composite application steps but with some clear mispractices such as low frequency of selective etching, less etchant washing, and the preference of vertical layering. Moreover, results from the current investigation should direct curricular updates in the future.

“…Ağız içerisinde karmaşık çiğneme kuvvetleri, pH değişimleri, yüksek mekanik stres, polimerizasyon büzülmesi, su emilimi, renk bozulması ve daha spesifik olarak klinik ömürlerini tehlikeye atabilecek mikrobiyal saldırılarla karşı karşıya kalmak kompozitin uzun süreli performansı için risk faktörleridir. 2,3 Diş hekimliğinde dental restorasyonlarda sıklıkla kullanılan kompozit rezinler, estetik sonuçlar alınabilmesi, kullanımlarının kolay olması, oral ortamda uzun süre stabil kalabilmeleri açısından tercih edilirler. Bu nedenle uygulanan kompozit materyal sertlik, çözünürlük ve yüzey direnci gibi fiziksel özelliklerinin de iyi olması beklenmektedir.…”

Amaç: Bu çalışmanın amacı yeni mikrohibrit özellikli bir dental kompozitin mekanik özellikle-rinden yüzey pürüzlülüğü ve mikrosertliğini piyasada yaygın olarak kullanılan farklı mikrohibrit ve nanohibrit kompozitlerle karşılaştırmaktır. Yöntem: Yeni üretilen Dolgunn(Himg Seramik ve Medikal Kompozit San.Tic. Ltd.Sti, Türkiye) kompoziti, G- aenial(GC, Japonya) ve Filtek Z250(3M, USA) ile hazırlanan örneklere mikrosert-lik test cihazı ile ölçümler yapıldı. Yüzey pürüzlülüğü testi için Dolgunn, G- aenial, Ceram.x Spectra (Dentsply Sirona, Germany) ve Filtek Ultimate (3M, USA) örneklerine Clearfil Twist Dia (Kuraray, Japan) ve Soft-lex (3M, USA) sistemleri uygulandı. Yüzey mikrosertliklerinin karşılaş-tırılması tek yönlü varyans analizi ANOVA ve çoklu karşılaştırmalarda Tukey HSD testi, yüzey pürüzlülüklerinin karşılaştırılmasında Kruskal-Wallis ve Wilcoxon testleri kullanılmıştır. Bulgular: Bulgular incelendiğinde Dolgunn ve Filtek Z250 kompozitleri arasında mikrosertlik değerleri açısından farklılık bulunmamıştır(p=0.661). G-aenial kompoziti ise diğer kompozitler-den istatiksel farklı olarak daha düşük sertlikte bulunmuştur(p
