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.

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.

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.

Marginal microleakage in cemented complete crowns

The Journal of Prosthetic Dentistry, 1978
An in vivo study was developed to observe the penetration of 131INa around the margins of complete crown castings cemented with zinc phosphate cement with and without the application of different protective agents, with the following results. 1. Complete crowns cemented with zinc phosphate cement showed 131INa marginal leakage differences depending on ...

Microleakage through dentin after crown cementation

Journal of Endodontics, 1995
This study investigated the relationship between type of luting cement for artificial crowns and microleakage through dentinal tubules. Standardized preparations were made on intact human premolars, and crowns were made in a base metal alloy using conventional techniques.

Coronal microleakage.

Annals of the Royal Australasian College of Dental Surgeons, 2001
The microbiological aetiology of periapical periodontitis of endodontic origin is generally accepted. Therefore, bacterial entry into the tooth both initially and secondarily to endodontic therapy is not desirable. Dental restorations and then root fillings in series are intended to prevent recurrent bacterial entry by blocking the access cavity and ...

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 ...
