Comparison and evaluation of leakage flux on various types of dental magnetic attachment

open access: closed2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008
A dental magnetic attachment is a device to retain dental prostheses such as overdentures by magnetic attraction. As compared with mechanical attachments, the dental magnetic attachment has superior characteristics such as easy insertion, good esthetics and less lateral pressure to its abutment tooth. As a result, it has come to be used widely.

The marginal leakage of some dental cements in humans: a PIXE-microbeam approach

open access: closedAIP Conference Proceedings, 1999
The marginal leakage and water absorption of dental cements and restorative materials has been investigated by many authors with several techniques, some of which led to valid results. However, no technique could give, by itself, information both on leakage and water absorption, as these measurements usually need different investigations.

Evaluation of airway leakage using reinforced laryngeal mask during dental anesthesia with spontaneous breathing.

open access: closedActa anaesthesiologica Sinica, 2002
The purpose of this study was to evaluate whether manipulation or position change of the head during dental procedures for handicapped patients (mentally retarded) using a reinforced laryngeal mask airway for ventilation would lead to air leak.All patients had a reinforced laryngeal mask airway inserted after induction of anesthesia; anesthesia was ...

[In vitro evaluation of mercury leakage from dental amalgam using atomic absorption spectrophotometry].

open access: closedMinerva stomatologica, 1999
The use of silver amalgam as a tooth filler is under constant critical review because of its mercury content. After a review of the literature on this subject, in vitro spectrophotometry was used to assay the release of mercury by these amalgams in basal conditions.The experiment was conducted in two phases using standard doses of amalgam.

Comparison of 7 luting protocols and their effect on the retention and marginal leakage of a cement-retained dental implant restoration.

open access: closedThe International journal of oral & maxillofacial implants, 2006
To determine the cement bond strength and marginal leakage of castings cemented to implant abutments.Fifty-six titanium abutments and castings were divided into 7 groups (n=8), 1 for each cement. Castings were cemented to abutments using 1 of 3 resin-based cements (RES, RES-B, and RES-B-P), a resin-modified glass ionomer (GI), a polycarboxylate cement (

Experimental Marginal Leakage Around Dental Amalgams Placed in Artificial Cavities

Journal of Dental Research, 1984
Experimental marginal leakage of high- and low-Cu amalgam restorations placed in acrylic teeth, where the cavities were untreated or painted with denatured collagen and/or a CaP slurry, was assessed after specimens were stored in a 1% NaCl solution for ten days and for one yr. All specimens stored for ten days showed severe marginal leakage. High- and

Inhibition of the Biofilm Formation of Anaerobic Bacteria Involved in Secondary Caries by Dental Adhesive

Journal of Biomimetics, Biomaterials and Biomedical Engineering, 2023
Secondary caries is a type of carious lesion found at the margins of or next to an existing restoration after the filling has been used for a period of time.
