Microleakage of posterior composite restorations

Dental Materials, 1985
Abstract 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, 1991
The 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.

Microleakage around direct composite inlays

Journal of Dentistry, 1991
The purpose of this study was to compare the microleakage around direct composite inlays bonded with a dual cure luting composite into Class V type inlay cavities in extracted molar teeth. Bonding methods which included two cavity cleansing regimes and three bonding treatments were used.

Clinical considerations of microleakage

Journal of Endodontics, 1990
Most dental materials permit the microleakage of bacteria and bacterial products from oral fluids to reach dentin. Thus, an understanding of the clinical consequences of microleakage demands that we analyze the permeability characteristics of dentin.

Clinical evaluation of a microleakage test

Dental Materials, 1987
Abstract 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.

Microleakage Evaluation using Acetate Peel Technique

Journal of Clinical Pediatric Dentistry, 2011
Objectives: To evaluate and measure the interfacial space or the restoration cavity integrity for probable microleakage using acetate film; acetate peel technique under different magnifications. Study design: Premolar tooth was obtained and standardized class V restoration with Z-350 done both buccally and lingually.

Microleakage of Root-End Filling Materials

Journal of Endodontics, 2001
The purpose of this study was to evaluate the microleakage of various root-end filling materials using a fluid filtration system. Sixty extracted human single-rooted teeth were used. The crowns were removed, the canals prepared, and root-end fillings placed. The samples were divided into two control and five experimental groups.

A crown for clinically investigating microleakage

The Journal of Prosthetic Dentistry, 1991
This 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

Microleakage of Dentin Adhesive Systems

Journal of Esthetic and Restorative Dentistry, 1991
Five different dentin adhesives were evaluated under various experimental conditions (using different restorative materials, placement techniques, and specimen storage). A silver‐staining technique was used to detect microleakage. Pentra Bond II was less effective than Tenure in prevention of marginal leakage, but similar to Scotchbond 2 and Gluma.

MICROLEAKAGE OF AMALGAM ALLOYS: AN UPDATE

The Journal of the American Dental Association, 1996
Using 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.
