“…SEM observation shows that there is no significant difference between the strength of the ceramics and composite bond among the samples treated with HF acid and sandblasting. However, significant difference was recorded in the microstructure of the surface in Vita Enamic, Lava Ultimate and Cerasmart materials after the treatment [24].…”

“…In contrast to the bond between the conventional ceramics and composite cement, which shows fracture on the seal between ceramic and composite, in hybrid materials different results can be observed. Cekic-Nagas and associates [24] observed the lost of bond in 39% of samples Vita Enamic and composite cement inside the hybrid material due to the cohesive structural damages of the material, while cohesive fractures were not registered in Cerasmart samples. The bond strength was high in cohesively fractured samples.…”

“…The universal bond was used as a primer because it contains different functional components, such as 10-methacryloxydecyl dihydrogen phosphate (MDP) or silane, as addition to components, which were present in the previous widely used primers. Moreover, in previous studies regarding the bond between composites and hybrid ceramics, it was found that the bond is stronger when the adhesive solution contains MDP than when it contains only silane [24]. It is deemed that silane can improve the bond because hybrid ceramics also contains silica fillers.…”

Introduction: Urgent demand for high-esthetic material, which at the same time has the possibility of absorption of mastication stress, has led to the technological development of hybrid nanoceramics used in CAD / CAM technology. Aim: The aim of the study was to evaluate the effects of different surface modification of hybrid nanoceramic crowns on the quality of the cement retention and the influence of the mastication stress after one year of function. Material and methods: 50 hybrid nanoceramic CAD/CAM crowns (CERASMART, GC) are cemented on titanium implant abutments with self-adhesive resin cement (G-CEM, LinkAce). The samples were divided into five main groups according to surface treatment (n=10): I (sandblasted with 50 microns Al2O3), II (treated with CERAMIC PRIMER II, GC), III (treated with 5% hydrofluoric acid), IV (treated with combination of 5% hydrofluoric acid and CERAMIC PRIMER II), V (control, non-treated group). The samples were storaged during 24 hours at 37°C, thermocycled and loaded under 10 000 mechanical cycles loads (simulation of 12 months of function). Retention forces measured in Universal testing machine. The data were represented as mean ± standard deviation, and for statistical analysis ANOVA test was used. Results: The highest initial retention force was demonstrated in the group IV (6.99±1.18), followed by group I (6.22±1.29), group III (5,97±1,25), group II (5,86±1,17) and control group samples (4.92±1.19). A statistically significant decline in retention force was recorded in all tested groups, with the lowest decrease observed in samples treated with a combination of 5% hydrofluoric acid and CERAMIC PRIMER II (6.08 ± 1.03). Conclusion: Mechanical and chemical surface modification can strongly influence the retentions between resin cement and hybrid nanoceramics. The results from this study are suggesting that the most efficient clinical outcome is the combination of 5% hidrofluoric acid and CERAMIC PRIMER II.

“…19,20 Endocrown is a monoblock restoration achieved by combining the intraradicular post, the core, and the crown in one component can reduce number of adhesive interfaces that are prone for debonding. 21 According to Biacchi et al, lithium disilicate ceramics have shown greater resistance to compression forces in endocrown restorations, compared with traditional crowns supported on fiber posts. CAD-CAM ceramics such as, lithium disilicate reinforced ceramics, appear to be the best option for anterior tooth endocrown restorations.…”

Traditionally, calcium hydroxide was the material of choice for apexification technique. However, the disadvantages of this technique includes delayed treatment, improper apical seal and increased risk of root fractures. Research for improved biocompatible materials resulted in evolving of higher characteristic materials such as Biodentine, a tricalcium silicate cement that possesses good handling and bioactive properties. This report describes the case of a 13-year-old boy who had traumatised his upper right central incisor which stunted the growth of root leaving it with open apex. The treatment of apexification with Biodentine and PRF as matrix was done. Prosthetic rehabilitation of endocrown fabricated with Lithium disilicate ceramic was delivered. Follow-ups were performed at 3, 6 and 12 month. The promising clinical and radiographic outcome in this case demonstrated that Biodentine may be an successful alternative to the conventional apexification materials and endocrown can be a conservative alternative to post and cores in such cases.

Endodontik tedavi; çürük, kırık veya periodontal hastalıktan belirgin olarak etkilenen dişlerde, kök çevresi sağlığının sürdürülmesi için kök kanalından canlı bakteri ve toksinlerin uzaklaştırılması amacıyla uygulanmaktadır. Endodontik tedavili dişin uzun dönem başarısı sadece kök kanal tedavisine değil, aynı zamanda post-endodontik restorasyonun kalitesine bağlıdır. Geçmişte, yapısal olarak zayıflamış endodontik tedavili dişin post-endodontik restorasyonu çok sert materyallerle gerçekleştirilmekteydi. Son günlerde, dentini yakın bir şekilde taklit eden materyaller tercih edilmektedir. Bu dişlerin restorasyonu, restoratif materyalin tutuculuk ve direnci, kalan diş dokusunun okluzal kuvvetlere direnci, uygun koronal ve kök içi tıkama ve aynı zamanda estetik gibi gereksinimleri sağlayabilmelidir. Bu derlemede, aşırı harabiyete uğrayan endoodontik tedavili dişlerin protetik restorasyonları ve bu alandaki güncel gelişmeler irdelenmiştir. Anahtar kelimeler: Endodonti, prostodonti, dental restorasyon. SUMMARY Endodontic therapy is performed on teeth significantly affected by caries, fracture or periodontal disease, for eliminating viable bacteria and toxins from the root canal to sustain periradicular health. The long-term success of endodontically treated teeth depends not only on root canal therapy itself as well as the quality of the post-endodontic restoration. In the past, the post-endodontic restoration of endodontically treated teeth that is structurally weakened was performed with very rigid materials. Nowadays, the materials that simulate dentin closely are mostly preferred. Restoration of these teeth needs to fulfill the necessities such as retention and resistance of the restorative material, the resistance of the remaining dental tissue to occlusal forces, proper coronal and intraradicular obturation and also aesthetic. In this review, prosthetic restorations of severely damaged endodontically-treated teeth and the current innovations in this field have been clarified.
