Microleakage

Journal of Dentistry, 1992
A critical review of techniques used in the assessment of microleakage in dental restorations is presented. These techniques include the use of air pressure, bacteria, radioisotopes, electrochemistry, chemical tracers and dye penetration. Wide variations in methodologies are revealed.

Microleakage of root restorations

The Journal of the American Dental Association, 1988
This study evaluated the microleakage of various restorative materials placed in root surfaces. A minimum of 20 freshly extracted single-rooted teeth were used for each combination of restorative materials. Four preparations were made on the root surface and each restored with a different material.

Microleakage of Resected MTA

Journal of Endodontics, 2002
Forty-six single rooted extracted human teeth were used in this study. After cleaning and shaping, twenty canals were randomly selected for obturation with MTA placed in an orthograde manor (Group 1). Another twenty roots were obturated with gutta-percha and Kerr EWT sealer, using warm vertical compaction (Group 2). The apical 3 mm of each root in both

Microleakage and enamel finish

The Journal of Prosthetic Dentistry, 1978
Cavity preparations that are finished with hand instruments allow significantly less marginal leakage than those which are completed only with rotary instruments. This does not mean that hand-instruments walls are perfectly smooth; it only means that these walls allow less marginal leakage.

Microleakage of retrograde amalgams

Journal of Endodontics, 1985
In this two-part in vitro investigation, apical leakage was electrochemically analyzed in teeth with different thicknesses and compositions of dental amalgam. In part 1, the apices of 10 teeth each were filled with zinc-containing amalgam to a depth of 1 mm or 3 mm.

Microleakage : a review

Journal of Dentistry, 1976
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 indirect composite inlays

Dental Materials, 1989
The 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.
