The purpose of this study was to evaluate the clinical performance of two "packable" posterior composites: Prodigy Condensable (P) (Kerr) and Definite (D) (Degussa). Thirty-six patients participated in the study. A total of 78 restorations were made, 40 with D and 38 with P. Each patient received at least two restorations, one of each studied material. The(More)
The purpose of this study was to evaluate the clinical performance of two "packable" posterior composites: Prodigy Condensable/Optibond Solo—Kerr (PC-OS) and Definite/Etch & Prime—Degussa (D-EP). Thirty-six patients participated in this study. A total of 78 restorations (40 with D-EP and 38 with PC-OS) were made. Each patient received at least two(More)
The aim of this study was to analyze the diametral tensile strengths of three resin-modified restorative glass ionomer cements--Vitremer, Fuji II LC and Photac Fil and one compomer--Dyract. They were tested at 1 hour, 1 day and 1 week. Kratos testing machine was used to load the specimens at a cross-head speed of 0.5 mm/min. The data were analyzed by(More)
PURPOSE The purpose of this study was to evaluate the performance of multiple-surface restorations employing 2 different glass ionomer cements (GICs) and the Atraumatic Restorative Treatment (ART) approach in permanent molar teeth. METHODS This study examined 60 restorations--36 Class I restorations involving 2 or more tooth surfaces and 24 Class II(More)
PURPOSE The aim of this study was to evaluate the influence of ultrasonic treatment on the bond strength of glass-ionomer cements to dentin. MATERIALS AND METHODS Conventional (Fuji II: a; Ketac-Fil Plus: b), resin-modified (Fuji II LC Improved: c; Photac-Fil Quick Aplicap: d), and more viscous conventional (Ketac Molar: e) glass-ionomer cements were(More)
OBJECTIVE The aim of this study was to compare water sorption (WS) and solubility (WSB) of different dentin bonding agents (DBA) as regards classification and light-activation system. The null hypotheses were: (1) there is no difference among DBA with respect to water sorption and solubility; (2) there is no effect of light-curing source on water sorption(More)
The purpose of this study was to evaluate the microhardness of resin-based materials polymerized with a LED (light-emitting diode) light-curing unit (LCU) and a halogen LCU. Twenty cylindrical specimens (3.0 mm in diameter and 2.0 mm high) were prepared for each tested material (Z100, Definite and Dyract). Specimens were light-cured with two LCUs (Ultraled(More)
PURPOSE The aim of this study was to assess the 6-year performance of the ART (atraumatic restorative treatment) approach in Class III restorations in permanent teeth. MATERIALS AND METHODS A total of 127 ART Class III restorations, using Ketac-Molar (3M ESPE) ionomer cement, was performed in 58 adult patients by one experienced operator in 1998. After a(More)
The purposes of this study were to evaluate the diametral tensile strength and the water sorption of restorative (Fuji IX and Ketac Molar) and resin-modified glass-ionomer luting cements (ProTec Cem, Fuji Plus and Vitremer) mixed at both manufacturer and increased powder: liquid ratio, for their use in the Atraumatic Restorative Treatment. A conventional(More)
The clinical performance of two packable posterior composites, Alert (A)—Jeneric/Pentron and SureFil™ (S)—Dentsply, was evaluated in 33 patients. Each patient received one A and one S restoration, resulting in a total of 66 restorations. The restorations were placed by one operator according to the manufacturer’s specifications and were finished and(More)
