Marginal microleakage in cemented complete crowns
The Journal of Prosthetic Dentistry, 1978An 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, 1995This 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.

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, 1969Bilaterally 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 ...

Microleakage of five dentin bonding systems
Dental Materials, 1989Class V preparations were placed in the buccal surfaces of 60 extracted human teeth such that approximately half of the preparations were above the CEJ and half below. The teeth were restored with Gluma/Pekalux, Tenure/Perfection, Scotchbond 2/Silux Plus, XR bond/Herculite XR, and Optec/Pentrafil 2 according to manufacturers' instructions.

Coronal Microleakage: An Online Study Guide
Journal of Endodontics, 2008The Editorial Board of the Journal of Endodontics has developed a literature-based study guide of topical areas related to endodontics. This study guide is intended to give the reader a focused review of the essential endodontic literature and does not cite all possible articles related to each topic. Although citing all articles would be comprehensive,

[Microleakage: evaluation and treatment].
Nederlands tijdschrift voor tandheelkunde, 1991Microleakage is a biological phenomenon with several implications. The affective component patient hyperalgesia (pain/hypersensitivity) of dentin which is a function of episodic hydrodynan (fluid) movement. The effective component is the disease process which signals the dentin-pulp complex to respond by disposition of sclerotic and/or reparative ...

[Microleakage and pulp protection].
Nederlands tijdschrift voor tandheelkunde, 1991Clinically undetectable leakage around amalgam and composite restoration, normally referred to as microleakage, will cause a bacterial invasion of the dentinal tubules. Such an invasion demands precautions. Although without a protective base many patients do not have complaints, this does not imply that the pulp is not affected. Therefore, dentin which
