Clinical evaluation of a microleakage test
Dental Materials, 1987Abstract Microleakage of amalgam restorations traditionally has been carried out in the laboratory. The present study deals with use of calcium hydroxide as an agent to detect microleakage. This method provides a major difference from previous studies in that the detecting agent leaks from whithin to the outer environment.

The effect of thermocycling in microleakage analysis
Dental Materials, 1992The purpose of this study was to evaluate the effect of thermocycling on dye penetration during in vitro microleakage analysis of composites. Fifty non-carious human molars, stored in 75% ethanol, were divided into five groups (N = 10). Each tooth was prepared for a MOD slot preparation using a high speed handpiece and water, one proximal cervical ...

A crown for clinically investigating microleakage
The Journal of Prosthetic Dentistry, 1991This investigation evaluated a cast crown with an access port for in vivo microleakage studies. Fifteen complete cast crowns containing an access port in the facial surface were cast. The gingival margins of the crowns were modified to test the sealing ability of the access port. Each casting was thermocycled 750 times at 5 degrees to 60 degrees C over

Abstract Microleakage may be defined as the passage of bacteria, fluids, molecules or ions between a cavity wall and the restorative material applied to it. Many techniques have been devised to test the cavity-sealing properties of restorations both in vitro and in vivo .

MICROLEAKAGE OF AMALGAM ALLOYS: AN UPDATE
The Journal of the American Dental Association, 1996Using an in vitro air pressure test, the authors found a wide variation in the microleakage characteristics of amalgam restorations made from 33 recently manufactured precapsulated alloys. Spherical particle alloys as a group exhibited the highest microleakage values.

Microleakage of indirect composite inlays
Dental Materials, 1989The purpose of this in vitro study was to evaluate the microleakage of indirect composite inlays and to compare leakage of inlays with directly placed composite restorations. Standardized MOD preparations were cut in 50 extracted human molars. One gingival margin was placed in enamel above the CEJ, and the other was placed in dentin below the CEJ.

BACKGROUND The available evidence of Er,Cr:YSGG lasers on bleached enamel is limited and controversial. It is assumed that Er,Cr:YSGG laser will be effective in reversing the effect of bleaching on adhesive bond integrity of enamel to resin composite ...

Microleakage of posterior composite restorations
Dental Materials, 1985Abstract Several composite restorative resins have recently been introduced for use in posterior teeth. A number of dentin bonding agents are commercially available for use in conjunction with composite restorative resins. The objective of this in vitro study was to evaluate the microleakage of Class II MOD preparations in extracted human mandibular ...

Microleakage in porcelain laminate veneers
Journal of Dentistry, 1991The effectiveness of two dentine-enamel bonding agents has been investigated in vitro when used together with an unfilled, low viscosity resin in eliminating the microleakage of porcelain laminate veneers. The restoration margins were located below and above the amelocemental junction of extracted maxillary central incisors.
