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.

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 Seven Dentin Bonding Agents

Journal of Esthetic and Restorative Dentistry, 1990
The purpose of this study was to evaluate the ability of seven dentin bonding agents to reduce dye penetration at the margins of microfill composite restorations in dentinal cavities.Forty extracted molars were selected and cleaned. Cavity preparations were made in dentin with #55 carbide burs.

Modification of the restoration protocol for resin-based composite (RBC) restoratives (conventional and bulk fill) on cuspal movement and microleakage score in molar teeth.

Dental Materials, 2018
OBJECTIVE To modify the resin-based composite (RBC) restoration protocol for standardised Class II cavities in third molar teeth restored using conventional RBCs or their bulk fill restorative counterparts.

Microleakage of intermediate restorative materials

Journal of Endodontics, 1990
This study compares the microleakage of a glass ionomer cement, Ketac Fil, used without cavity conditioning, with the established intermediate restorative materials, Cavit-W, and a reinforced zinc oxide-eugenol cement, Kalzinol. Microleakage was assessed using an electrochemical technique.

Comparison of micro-CT and conventional dye penetration for microleakage assessment after different aging conditions

International Journal of Adhesion and Adhesives, 2019
Aim The aim of this study was to compare microleakage assessment by micro-tomography (micro-CT) and conventional microscopy in class V restorations after different aging treatments.

Microleakage in endodontics.

Journal of international oral health : JIOH, 2015
A three-dimensional obturation and complete coronal and apical seal is one the important aims of root canal treatment. Since microorganisms may remain in the root canal system after instrumentation, a tight apical seal is desired to prevent bacteria and their by-products from invading the apex.
