This study explored an alternative approach using rheology to assess setting time. The following cements were tested: ProRoot® MTA (Dentsply, Tulsa, OK, USA), Biodentine® (Septodont, Saint Maur des Fosses, France), Fuji VII®, FujiVII® EP, and Fuji IX® (from GC Corporation, Tokyo, Japan), RealSeal SE™ Sealer (SybronEndo, Amersfoort, The Netherlands), AH 26® and AH Plus (both from Dentsply DeTrey...

Background: The use of Glass ionomer cements (GIC) as restorative materials is beneficial due to fluoride release and ease of application. Strength and solubility are important properties that can affect the longevity of restorative materials in the oral environment. Aim: The objective of this study was to evaluate compressive, diametral tensile strength and solubility of a nanofilled GIC (Keta...

The purpose of this study was to evaluate gray mineral trioxide aggregate (MTA), white MTA, and Fuji II LC cement as coronal barriers to bacterial leakage. Seventy-eight, matched, human teeth were obturated with gutta-percha. In group I, 18 pairs received a 3-mm barrier of gray or white MTA. In group II, 18 pairs received a 3-mm barrier of gray MTA or Fuji cement. Three pairs were used as posit...

In 8 male rats instrumental responses reinforced by contact with an estrous female with an intact or a surgically closed vagina were investigated. Contact with the female lasted until the end of the mount bout. It was observed that neither the rewarding value of the mount bout (expressed by the duration of the response) nor its arousing properties (expressed by the rate of bar presses) depended...

AIM Recent advances including the incorporation of antibacterial substances, such as chlorhexidine, into restorative materials such as glass ionoer cement (GIC), might alter the physical properties of the material, which might affect the marginal seal of the restorations. Hence, the objective of this study was to compare the marginal sealing ability of GC Fuji IX modified with 1% chlorhexidine ...

BACKGROUND Glass ionomer (GI) restorations exposed to fluoride have the ability to slowly release fluoride. Therefore, the aim of this study was to investigate fluoride release from three GIs before and after exposure to sodium fluoride (NaF) and acidulated phosphate fluoride (APF). MATERIALS AND METHODS Fifteen disc-shaped samples (6 mm in diameter and 2 mm in thickness) from three GIs (Fuji...

First printed in 1831, ‘Red Fuji' by Hokusai is one the most iconic Japanese woodblock prints and thousands of impressions were from its original set woodblocks, often different colour schemes using printing effects for editions. The aim our research was to systematically study these variations determine chronological order which they had been introduced. First, we located 93 surviving Red Fuji...

A combined hydraulic engine mount and buffer is proposed in this study for use in the mid-priced vehicle. In some vehicle design projects, an engine is selected to use in a new car design. To achieve the desired vibration conditions, the mount can be redesigned with exorbitant costs and long-term research. The idea of using a buffer in the combination of the conventional engine mount is to sugg...
