The aim of this study was to evaluate the bond strength of three different calcium silicate based cements (Biodentine, NeoPutty and MTA Cem LC) with two different bulk fill composites (fiber-reinforced and non-fiber-reinforced). Plexiglas molds with a diameter of 4 mm and a thickness of 2 mm were prepared (n=60). Each CBC was mixed according to the manufacturer’s instructions and placed in plexiglass molds. The BD, NP, and MTA Cem LC samples were then randomly divided into 2 subgroups containing 10 samples each. The surfaces of the samples were air dried and Single Bond universal adhesive was applied. Then, cylindrical plastic capsules of 2 mm height and 2 mm inner diameter belonging to Filtek Bulk fill and EverX Posterior composite resin groups were centered on the coating material and polymerized for 20 seconds. After SBS testing, all samples were examined by scanning electron microscopy (SEM) to identify failure patterns. Three samples, one from each group, were prepared to evaluate the chemical compositions of the materials. Samples were prepared using plexiglass molds with a diameter of 10 mm and a thickness of 2 mm. The materials were then examined with an energy dispersive X-ray spectroscopy for surface elemental analysis. The values obtained from the tests were evaluated as statistically significant (p < 0.05). After SBS testing, the difference between all CBCs was statistically significant in both compound groups. According to the findings obtained from this study, it was concluded that MTA Cem LC had the highest SBS values in both composite groups.
Neonatal-progeroid syndrome known as Wiedemann Rautenstrauch syndrome (WRS) is an extremely rare, autosomal recessive disorder. Neonatal progeroid disease characterized by progeroid appearance growth retardation, lipodystrophy, an unusual face (triangular shape, sparse hair, small mouth, macrocephaly, pointed jaw), thin skin, hard and thick joints and dental anomalies (newborn tooth; hypodontics). A 5-year-old boy case diagnosed with hypodontics is presented. In this case, a child prosthesis was performed to facilitate the nutrition of the patient and to increase the quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
