BACKGROUND AND OBJECTIVES This study was to evaluate the feasibility of using a novel chitosan hemostatic dressing to control hemorrhage and urinary leakage by sealing off the parenchymal wound following LPN. METHODS Nine heparinized domestic swine underwent bilateral laparoscopic partial nephrectomies involving either a polar or wedge resection. Estimated blood loss (EBL), hemostatic score, ...

The study was done to assess the sealing ability and adaptation of RealSeal 1, and to compare it with Thermafil. 65 single-rooted extracted teeth were selected and root canal treatment was performed. Root canals were obturated with RealSeal 1 or Thermafil. A double chamber bacterial leakage model using E. faecalis was developed to assess the sealing ability. Samples were monitored daily for 60 ...

Introduction: Endodontic treatment failure is caused by the leakage of microorganisms and endotoxins, which leads to pathological lesions. Adequate seal of the root canal is essential to preventing recontamination and ensuring the long-term clinical success rate. Mineral trioxide aggregate (MTA) and calcium-enriched mixture cement (CEM) are common types of cement with adequate ...

Analysis of laser assisted frit sealing processes for high CTE > 5x10/°C (coefficient of thermal expansion) glasses was done. The method is based on the thermal fusion of two glasses with a low melting point glass frit. This method is used when thermal sensitive materials such as OLED (organic light emissive device) are present in the glass package. The frit is selected to be highly absorbent a...

The aim of this study was to compare the genotypic diversity and virulence traits of Streptococcus mutans isolated from carious dentin before and after partial dentin caries removal (PDR) and sealing. Carious dentin samples were obtained three months before and after the PDR and cavity sealing. Up to seven isolates of each morphological type of S. mutans were selected and strain identity was co...

Background Bonded indirect restorations are laboratory fabricated and requires at least two appointments: one for provisionalization and one for luting. In the first appointment, an impression is immediately taken after tooth preparation, followed by a provisional treatment, which traditionally consists of luting a temporary restoration. After the indirect restoration fabrication, the temporary...

In situ X-ray diffraction was used to study the interactions of the PNNL G18 fuel cell sealing glasses with the oxides that form on candidate interconnect alloys and with the ebrite alloy. Experiments under 4% hydrogen and air at temperatures up to 1000 °C showed that both sealants react rapidly with alumina and chromia, but not with NiO. The crystallization of the high-CTE phase BaCrO4 was not...

This paper describes two recent applications of aerosol sealing techniques in buildings for improving indoor air quality and reducing energy required for heating, cooling, and ventilation. One application applies a commercially-available duct sealing technology, which has typically been used in single-family applications, to large-building exhaust systems. The initial leakage rates, percent lea...
