Purpose This study aimed to examine novel techniques using prototype endodontic obturators obturate a resin-based sealer. Methods Powder-liquid ratios of MetaSEAL Soft were changed obtain suitable root canal sealing, and the physical properties for various powder-liquid analyzed according ISO-6876. Tensile bond strength was also examined. Prototype with combination thread numbers pitch angles s...

The requirements on service life of reinforced concrete structures, as prescribed by design codes, may be difficult to fulfilled in highly aggressive environments such marine ones, which premature degradation is most likely occur. In the aforementioned situations, avoid expensive repair activities, different protective systems, including, among others, self-healing concrete, could adopted. Rese...

The concept of an embodied intelligent agent is a key in modern artificial intelligence and robotics. Physically, open system embedded environment that it interacts with through sensors actuators. It contains learning algorithm correlates the sensor actuator results by features about its environment. In this article we present simple optical uses light to probe learn components our scenario, qu...

background: marginal seal has a principal role in durability and clinical success offissure sealants. the aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application. methods: the 55 extracted premolars were assigned randomly to one ofthe following five groups: group 1: acid-etching (ultra-etch) + fissure sealant (conv...

The notion that modern buildings should strive to be net-zero energy (NZEBs) is widely accepted. One of the causes leading high usage for space heating, resulting in avoidable carbon emissions, heat loss via building windows. In order improve window’s insulation existing buildings, structured-core transparent vacuum panels (TVIPs) are proposed. TVIPs mainly consist structured core material, low...

Grout is a binding agent or binder often used with building materials to improve their durability functions. It may be organic or inorganic material used for sealing or consolidation of cracks, pores, or voids in order to improve the mechanical properties and impermeability of a particular system, whether soil, cementitious or of other building materials. Grouts act as dispersion agents where d...

This study evaluated the effect of sealants on enamel demineralization, focusing on physical protection of the sealed enamel and fluoride protection of the adjacent unsealed enamel. Occlusal fissures with areas measuring 12 mm2 were delimited in 48 extracted molars, randomly divided into 4 groups (n =12): 1) no sealing; 2) sealing with a resin-modified glass-ionomer (Vitremer, 3M ESPE); 3) seal...

STATEMENT OF THE PROBLEM Alkaline pH can affect the physical and chemical properties and sealing ability of apical plug material. Calcium hydroxide is used as an intracanal medication to complete disinfection of root canals. It raises the pH of environment to alkaline value. PURPOSE The aim of this in vitro study was to evaluate and compare the effect of alkaline pH on the sealing ability of ...

BACKGROUND/AIM Anastomotic leakage remains a frequent and serious complication in gastrointestinal surgery. In order to reduce its incidence, several clinical and experimental studies on anastomotic sealing have been performed. In a number of these studies, the sealing material has been fibrin glue (FG), and the results in individual studies have been varying. The positive effect of anastomotic...
