Film thickness of dental luting cements

Dental Materials, 1986
Abstract The film thickness as a function of time after start of mixing was measured for several dental luting cements (one zinc phosphate, 2 polycarboxylate and 3 glass ionomer cements) with 2 different methods, i.e., between 2 plane plates as used to control film thickness in several specifications/standards (Method 1), and in a crown-tooth model ...

Conversion of dual cure luting cements

Journal of Oral Rehabilitation, 1995
summary This investigation determined the efficiency and rate of cure of polymeric luting agents when cured under manufacturers' instructions with the appropriate visible light source, and under conditions where light was excluded and curing was reliant on the chemical reaction only.

Destructive Stresses in Adhesive Luting Cements

Journal of Dental Research, 1991
In this study, curing shrinkage stress development was monitored in a glass-ionomer and a BisGMA composite luting cement adhesively placed at film thicknesses ranging from 30 to 200 μm. The nature and magnitude of the stress development depended greatly on the formulation and film thicknesses of the lute.

Mechanical properties of dental luting cements

The Journal of Prosthetic Dentistry, 1999
Dental luting cements fail by microcrack formation and bacterial ingress or by gross failure and crown dislodgment. Both of these failure modes are related to mechanical properties and deformation.This study evaluated those mechanical properties of cements. METHODS AND MATERIAL.

Porosity of different dental luting cements

Dental Materials, 2007
The aim of this in vitro study was to compare open porosity and pore size distribution of different types of luting cements (zinc phosphate and polycarboxylate produced by Harvard Cement, Great Britain, glass-ionomer product GC Fuji I, GC Corporation, Japan, and Panavia F, resin based composite cement, Kurraray Co. Ltd.

Implant Luting Cements

2014
Dental luting cements have in general been exclusively designed for the natural tooth, with features that allow for reduction in caries, adhesion to natural tooth tissues, and radiographic appearance often related to dentine. Although many of these properties are redundant when considering restoring dental implants, studies show clinicians frequently ...

Evaluation of glass ionomer luting cements

European Journal of Oral Sciences, 1983
Abstract – In the present study the three glass ionomer luting cements available on the Scandinavian market in June, 1982 were evaluated by comparison with a zinc phosphate and a zinc carboxylate cement. The following properties were tested: effective maximum grain size, retention, strength, bond strength to dentin, disintegration in and absorption of

Degradation of Luting Cements Measured in vitro

Journal of Dental Research, 1982
The degradation of luting cements was made visible and measurable when these cements were held as a cement layer, The degradation process, which is mostly a sequence of absorption disintegration and solution, could be expressed in a time-constant (r).

The influence of temporary cements on dental adhesive systems for luting cementation

Journal of Dentistry, 2011
This study tested the hypothesis that bond strength of total- and self-etching adhesive systems to dentine is not affected by the presence of remnants from either eugenol-containing (EC) or eugenol-free (EF) temporary cements after standardized cleaning procedures.Thirty non-carious human third molars were polished flat to expose dentine surfaces ...
