13. Degree of conversion and bond strength of resin-cements to feldspathic ceramic using different curing modes
Abstract Resin cements have led to great advances in dental ceramic restoration techniques because of their ability to bond to both dental structures and restorative materials. Objective The aim of this study was to assess the performance of resin cements when different curing modes are used, by evaluating the degree of conversion and bond strength to a ce

14. Evaluation of dentin hypersensitivity treatment with glass ionomer cements: A randomized clinical trial
Abstract A randomized, double-blind, split-mouth clinical trial was performed compared the desensitizing efficacy of the resin-modified glass ionomer cement (GIC) ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional GIC Vidrion R (SS White, Gloucester, UK) in a 6-month follow-up. Subjects were required to have at least two teeth with dentin hypersensi

15. Push-out bond strength of MTA HP, a new high-plasticity calcium silicate-based cement
Abstract This study was designed to investigate the resistance to dislodgment provided by MTA HP, a new high-plasticity calcium silicate-based cement. Biodentine and White MTA Angelus were used as reference materials for comparison. Three discs 1 ± 0.1 mm thick were obtained from the middle third of the roots of 5 maxillary canines. Three 0.8-mm-wide holes

17. Effect of addition of nano-hydroxyapatite on physico-chemical and antibiofilm properties of calcium silicate cements
ABSTRACT Objective Mineral Trioxide Aggregate (MTA) is a calcium silicate cement composed of Portland cement (PC) and bismuth oxide. Hydroxyapatite has been incorporated to enhance mechanical and biological properties of dental materials. This study evaluated physicochemical and mechanical properties and antibiofilm activity of MTA and PC associated with z

20. Preference for using posts to restore endodontically treated teeth: findings from a survey with dentists
The aim of this study was to evaluate if clinical experience, whether in relation to length of practice time and/or level of specialization influences the dentist’s preference for using posts to restore endodontically treated teeth. A cross sectional study was carried out using a questionnaire with dentists (n = 276) in Pelotas, southern Brazil. Data were

22. Influence of acid etching on shear strength of different glass ionomer cements
AIM: To assess the influence of dental etching on the shear strength of different glass ionomer cements. METHODS: The crown of 60 bovine incisors was prepared to obtain a flat, smooth surface, were attached to a PVC tube and randomly divided into six groups: Group 1 - Riva Self Cure without etching; Group II - Riva Self Cure with pre-etching; Group III - Max

23. Resistência adesiva dos cimentos resinosos convencionais e autoadesivos à dentina contaminada por saliva / Bond strength of different composite resin cements and dentin interfaces contaminated with saliva
Many dental injuries require indirect restorations fixed by adhesive cements. In some situations is not possible to isolate the operative field, which can lead to contamination by saliva of the dentin. The aim of this study was to analyze the treatment of dentin contaminated with saliva on shear bond strength of conventional and self-adhesive resin cements.
