objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
BACKGROUND This study evaluated the fluoride release and uptake of five common dental restoratives mainly glass ionomer formulations, including a conventional glass ionomer, a relatively new caries stabilization glass ionomer and resin-modified glass ionomer (Fuji II, Fuji VII and Fuji II LC); one compomer (F2000); and one fluoride releasing composite resin (tetric ceram). MATERIALS AND METHO...
background. this study evaluated the effect of two prophylaxis techniques on the marginal gap of ci v resin-modified glass-ionomer restorations. methods. standard cl v cavities were prepared on the buccal surfaces of 48 sound bovine mandibular incisors in this in vitro study. after restoration of the cavities with gc fuji ii lc resin-modified glass-ionomer, the samples were randomly assigned to...
This study investigated the proliferation and differentiation potential of pluripotent mesenchymal cells on three resin-based restoratives using a typical pluripotent mesenchymal precursor cell line, C2C12. C2C12 cells were cultured for 3-21 days on cured specimens of a Bis-GMA/TEGDMA-based composite resin (APX; Clearfil AP-X), a 4-META/MMA-based resin cement (SB; Superbond C&B) or a HEMA-conta...
OBJECTIVE The objective of this study was to evaluate the effect of desensitizing agents containing different amounts of fluoride on the shear bond strength of a dual polymerized resin cement and a resin-modified glass ionomer cement (RMGIC) to dentin. MATERIAL AND METHODS One hundred human molars were mounted in acrylic resin blocks and prepared until the dentin surface was exposed. The spec...
UNLABELLED (Full text is available at http://www.manu.edu.mk/prilozi). OBJECTIVES The study was aimed at determining the effectiveness of fluoride-releasing materials (conventional and resin-modified glass-ionomers, compomer and fluoride-releasing composite resin) in inhibiting demineralization of restored teeth in an artificial caries medium. METHODS A total of 72 teeth (36 deciduous and 3...
Introduction: Recently, such alternative methods for tooth preparation as laser irradiation have been studied increasingly, though limited numbers of studies have been conducted in regard with primary teeth. Microleakage involves one of the prominent criteria in evaluating success of adhesive restorative materials. Therefore, the objective of this in vitro study was to compare marginal microle...
PURPOSE This study compared the influence of two luting cements on the clinical performance of single crowns. MATERIALS AND METHODS Twenty patients received 39 pairs of metal-ceramic and Procera crowns cemented with zinc phosphate and resin-modified glass-ionomer luting cement (Vitremer) in a split-mouth randomized pattern blinded to the recipient. The crowns were examined immediately after c...
