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, 1978Cavity 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, 1985In 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.

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, 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.

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.

Microleakage around direct composite inlays
Journal of Dentistry, 1991The 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.

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 ...
