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.

Marginal microleakage—an in vivo assessment

The Journal of the American Dental Association, 1969
Bilaterally paired mandibular teeth scheduled for extraction were chosen for in vivo and in vitro studies of marginal leakage. Decided contrast in test results indicates that marginal microleakage should be determined in vivo. Animal and human tests both show that the removal of a tooth from its organism is decisive in studies of marginal leakage ...

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.

Investigation of microleakage between titanium and porcelain

Journal of Oral Rehabilitation, 1999
Porcelain was applied to 30 titanium and 30 Remanium CS® disc‐shaped frameworks in order to investigate the microleakage. Each group was divided to three subgroups each containing 10 specimens and representing the different firing cycles (10 specimens for opaque+dentine; 10 specimens for opaque+dentine+enamel; and 10 specimens for opaque+dentine ...

Microleakage of porcelain laminate veneers cemented with different bonding techniques

Journal of Clinical and Experimental Dentistry, 2018
Background Porcelain laminate veneers (PLV) are continued to be popular in modern dental practice due to its high aesthetic outcome and conservative tooth preparation.

Microleakage—Full crowns and the dental pulp

Journal of Endodontics, 1992
Recent studies have described microleakage under full crowns cemented with several different cements. This study tested three different types of crown margin preparations--a chamfer, a shoulder, and a shoulder plus a bevel to determine whether or not the margin preparation could affect microleakage.

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.

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.

Microbial microleakage and pulpal inflammation: A review

Dental Traumatology, 1986
Abstract The evidence relating microbial microleakage and pulpal inflammation is reviewed. In vitro experiments show that all current dental materials permit fluid microleakage at the material/cavity wall interface. in vivo, this fluid microleakage is accompanied by bacterial growth, unless the material has lasting antibacterial properties.
