The evaluation of microleakage and fluoride release of different types of glass ionomer cements

Nigerian Journal of Clinical Practice, 2019
Background: The aim of this study was to evaluate six different glass ionomer cement (GIC)-based restorative materials through comparisons of microleakage and fluoride release.

Shear bond strength and microleakage of novel glass-ionomer cements: An In vitro Study

Nigerian Journal of Clinical Practice, 2019
Background: The overall success of dental restorations depends on the materials' ability to bond to dental structures and to eliminate the microleakage.

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

Review of microleakage evaluation tools

Journal of International Oral Health, 2017
The advancement of restorative materials and techniques continues to enhance the clinical success of numerous restorative procedures. Despite these new innovations, microleakage persists as one of the main causes of restoration failure.

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.
