Clinical Studies of Plaque Control Agents: An Overview
Authors: Lobene Ralph R. 
Published: November 2010

Dental plaque is massed packed bacterial cells which accumulate on the supra- and subgingival surfaces of the teeth as well as on the oral mucosa. The microorganisms of plaque have been shown to be associated with both dental caries and periodontal disease. This overview of clinical studies of plaque control agents reviews the properties and effects of chemical compounds which have demonstrated a potential for the control of plaque microorganisms. The search for clinically effective antiplaque agents has been stimulated by findings in laboratory and animal studies of plaque dynamics. Based upon these in vitro and in vivo experiments, chemotherapeutic agents such as antibiotics, antiseptics, enzymes, detergents, bacteriosides, antimetabolites, and oxidizing agents have been evaluated against human plaque microorganisms using the ultimate biological model — man. Continued study of chemotherapeutic agents should be encouraged because many of these drugs have been shown to be safe for human use and may require only the development of a delivery system to potentiate their concentration in a specific local site. Use of these chemotherapeutic agents, which can be self-administered, becomes an attractive way of providing the public with a cost-effective method of preventing caries and periodontal disease.
Dynamic Mechanical Properties of Resin-based Filling Materials
Authors: Whiting R. , Jacobsen P.H. 
Published: November 2010

The elastic moduli and mechanical damping of a range of polymeric restorative materials have been determined using a torsion pendulum. Composite materials have high moduli and low damping compared with unfilled resin. These materials have stable mechanical properties, but variation occurred as a result of different specimen conditioning methods. Non-destructive testing was valuable in that it allowed repeated testing of a single specimen.
Mechanical Tests of Smooth Silver-plated Retention Pins in Amalgam
Authors: Galindo Y. , McLachlan K. , Kasloff Z. 
Published: November 2010

Retention and stress concentration factors can be improved if a good mechanical bond exists between smooth retention pins and an amalgam restoration. It is shown that, by silver-plating pins and by using a rubbing technique during condensation of the amalgam, a good mechanical bond is produced. Mechanical tests of this bond show that its shear strength is adequate to withstand the stresses likely to be produced by occlusal forces. The form of the tests was: (a) torsion, to demonstrate the performance of the bond in shear and (b) push-through, to provide stress distributions more closely allied to those found under clinical conditions. Plain stainless steel and plated stainless steel pins were compared for their performance, and sterling silver pins were used for checking the validity of the torsion test method. It is concluded from these tests that, with the plating and "rubbing" techniques mentioned, a good mechanical bond is produced which is likely to have value in clinical dentistry.

Authors: Rouleau Joanne , Ladouceur Robert , Dufour Laurent 
Published: November 2010

The present study attempts to verify the relative efficacy of two forms of pre-exposure which are identical in content and parallel in mode of exposure (in vivo or videotape). These two forms of pre-exposure were given to 38 children, aged four to six years old, before their first dental visit. The results showed that all groups manifested relatively little negative behavior while seeing the dentist. The theoretical and methodological implications of this study are discussed.

Authors: Baghdady Virgin S. , Ghose Leonora J. , Enke Helmut 
Published: November 2010

This epidemiological study describes the prevalence of trauma to the anterior teeth of 6090 Iraqi and 3507 Sudanese primary school children. 7.7% of Iraqi and 5.1% of Sudanese presented incisal trauma. The male to female ratio was 1.3:1 in Iraqis and 2.6 :1 in Sudanese. The frequency of trauma to Iraqi females below age nine yr was higher than the males, but the condition was reversed with age. In Sudanese children the frequency was higher in males in all age groups. In general, males suffered a higher rate of trauma in both countries, but the Iraqi children had a significantly higher rate of trauma than the Sudanese in both sexes.
Sexual Dimorphism in the Emergence of the Deciduous Teeth
Authors: Tanguay R. , Demirjian A. , Thibault H.W. 
Published: November 2010

Exact ages of emergence of the twenty deciduous teeth have been investigated on a longitudinal sample of 195 French-Canadian children (113 boys and 82 girls). A multivariate analysis of variance yielded a significant overall sex difference (p<O. 0001). It has been found that the emergence of the deciduous dentition in boys is more precocious than that in girls by about one month; this difference is present at the emergence of the upper central incisor and is maintained henceforth. The only notable exception to this pattern is the emergence of the first molars. Results of the present study, combined with those of previous research, suggest that sexual dimorphism in the emergence of the deciduous teeth could be mediated through ethnic factors.
A Physicochemical Bench-scale Caries Model
Authors: Chow L.C. , Brown W.E. 
Published: November 2010

A diffusion cell comprising two compartments separated by a commercial membrane of known ion permselectivity was used as an experimental model to study factors which may affect caries formation. One compartment (the "lesion") contained an excess of hydroxyapatite or fluorapatite crystals, and its solution was kept near saturation by stirring. An unsaturated acidic calcium phosphate solution flowed continuously through the other compartment (the "plaque-saliva"), thus providing the driving force for dissolution of the crystals as modified by the permeability of the membrane and/or the presence of fluoride. Calcium, phosphate, fluoride, and chloride concentrations, pH, and membrane potential were measured at steady state. The permselective character of the membrane profoundly affected the solution in the "lesion": The initial Ca/P ratio of 1.6 was shifted, at steady state, to less than 1.1 ("neutral" membrane), to less than 0.48 (cation-permselective membrane), and to 3.3 (anion-permselective membrane). All the membranes caused Ca and PO4 concentrations in the "lesion" to increase (e.g., with the cation-permselective membrane, the Ca 22-fold and the PO4 75-fold). Substantial membrane potentials were encountered in all cases. The pH of the steady-state solution was always less than before diffusion was initiated; the average decrease was 1.1 units. In every case, the pH, and the Ca and PO4 concentrations of the F--containing solution were less than those in the F--free solution. The changes induced by the "neutral" membrane were unexpectedly large. In two cases, H3PO4 was diffusing against its chemical potential gradient at steady state. The results are relevant for understanding and for modeling of the caries process.
Materials Science Microprobe Analysis of Three High-copper Amalgams
Authors: Mahler D.B. , Adey J.D. 
Published: November 2010

Three single-composition, high-copper amalgams were analyzed for the composition of their before- and after-reaction phases. The method used was electron probe microanalysis. The results may be summarized as follows: (1) All alloys consist essentially of Ag3Sn (γ), Cu3Sn (∈), and, in some cases, Ag4Sn (β). (2) When the original alloy contains higher amounts of Cu, more Cu is found in solution in the Ag3Sn (γ) and Ag4Sn (β) phases. (3) The reaction phases in amalgams made from these alloys consist essentially of Ag22Sn Hg27(γ1) and Cu6Sn5 (η'), with no detectable Sn 8Hg (γ2). alloys. (4) When In is present, it is found principally in the Ag3Sn (γ) and Ag22Sn Hg 27(γ1) phases, and both the γ and γ1 phases are of different composition than that for the other (5) When Pd is present, it is found principally in the Cu3Sn (e), Cu6Sn 5 (η'), and Ag22Sn Hg27(γ1) phases.
Tarnish and Corrosion of a Commercial Dental Ag-Pd-Cu-Au Casting Alloy
Authors: Niemi L. , Holland R.I. 
Published: November 2010

The correlation between microstructure, tarnish, and corrosion behavior of a commercial dental Ag-Pd-Cu-Au casting alloy after various heat treatments was studied. The attacked structural components were identified by comparing SEM micrographs with light optical micrographs taken after exposure of the alloy to a 2% Na2S solution and after dynamic polarization in de-aerated artificial saliva. The characteristic dynamic polarization curves for the alloy after the heat treatments were established. The results were verified by analogous testing of two experimental alloys with compositions similar to those of the analyzed components in the commercial alloy annealed at 600°C for seven wk. The matrix of the commercial alloy was decomposed, according to the heat treatments, into varying proportions of a tarnish- and corrosion-resistant Cu- and Pd-rich component (A) and a non-resistant Ag-rich component (B). The presence of A considerably increased the tarnish rate of B, due to galvanic coupling. Age-hardening of the alloy increased the proportion of the tarnish- and corrosion-prone component B.
