determined daily for 10 days. The morphology of wires was observed using a seanning electron microscope, After imrnersion for 10 days, the initial micrehardness of the wires deereased by O.3-5.6% depending on the test solution. Dyract AP (DA) and F2000 (F2) (compomers) released signifieantly more fluoride than the ether resin products (composite resins) regardless of the test solution, In pH 2,...

The longevity of fixed partial denture depends on the type of luting cement used with tooth preparation. The clinician's understating of various cements, their advantages and disadvantages is of utmost importance. In recent years, many luting agents cements have been introduced claiming clinically better performance than existing materials due to improved characteristics. Both conventional and ...

background: prompt l-pop is a self-etching dentin adhesive, which is recommended to use with both compomers and composite resins. the aims of this investigation were to determine and compare the microleakage, shear bond strength, and shear push out strength of composite and compomer to dentin with application of prompt l-pop as adhesive system. methods: after application of prompt l-pop on the ...

PURPOSE More than five hundred million direct dental restorations are placed each year worldwide. In about 55% of the cases, resin composites or compomers are used, and in 45% amalgam. The longevity of posterior resin restorations is well documented. However, data on resin composites that are placed without enamel/dentin conditioning and resin composites placed with self-etching adhesive system...

BACKGROUND Recently, there has been an expansion in the range of tooth-coloured restorative materials available. In 1999, the National Health and Medical Research Council recommended clinicians use alternatives to amalgam in children 'where appropriate'. METHODS A three-part 29-item questionnaire was developed, tested in a focus group, and distributed to members of the Australasian Academy of...
