Published: November 2010

Total and insoluble dextransucrase activities of 10 strains of oral streptococci were measured by a modified filter disk assay. Strains that were nonadherent to hard surfaces had only low levels of insoluble dextransucrase activity. A physical rather than metabolic mechanism is suggested to explain the decreased insoluble and increased soluble activities observed when dextran T-10 is added to the media.
Enamel Proteins: Biosynthesis and Chemistry
Authors: Sasaki S. , Shimokawa H. 
Published: November 2010

Bovine ameloblast cell layer was incubated in 3H-proline containing medium and the incorporation of radioactivity into protein fractions of the cell and the medium was investigated by SDSpolyacrylamide gel electrophoresis. The results suggest that the ameloblasts synthesize and secrete a protein having a molecular weight of 25,000 daltons which is supposed to be the prototype of enamel proteins. This protein was degraded into dialyzable sizes by the cell extract. After a longer period of incubation another low molecular weight protein fraction appeared in the medium. Purification procedure with SDS gel filtration of the enamel protein is reported.

The Use of an Intermediate Resin in the Acid-etch Procedure: Retentive Strength, Microleakage, and Failure Mode Analysis
Authors: Prevost A.P. , Fuller J.L. , Peterson L.C. 
Published: November 2010

Three composite resin systems, one conventional (Concise) and two microfilled (IsoPast and Silar), used with and without an intermediate resin (Concise Enamel Bond), were evaluated with and without thermal stress for in vitro retentive strength and sealing ability to acid-etched human enamel. All three materials yielded significantly different shear strength values. The use of an intermediate resin significantly improved both the shear strength and resistance to microleakage of Silar, while no differences were observed for Concise and IsoPast. The thermocycling procedure did not generally or consistently affect the results. The failure mode of the three acid-etched composite resins was studied by evaluation of the failure surface and by describing the percentages of enamel, composite, and interface which were present. The use of an intermediate resin did not significantly influence the failure mode, and the correlation between the failure mode and retentive strength, although significant, was low. The study confirmed the importance of adequate wetting action of a resin on the etched enamel surface to ensure proper bonding.
A Model for the Implant-Bone Interface Characteristics of Porous Dental Implants
Authors: Cook S.D. , Klawitter J.J. , Weinstein A.M. 
Published: November 2010

The use of computer-aided design techniques, such as,finite element stress analysis, to evaluate implant designs requires that the mechanics at the interface between the implant and the bone be characterized, This problem is aecentuated when implants designed to achieve stabilization by tissue growth into parous coatings are used. A model has been developed to represent the mechanical properties of the porous material-bone interface. The model, which accounts for the mechanics of bane tissue grown into a porous implant surface, was also developed so that it could be incorporated into a three-dimensional finite-element analysis, The analytical results from a three-dimensional finite-element model af a cylindrical porous rooted dental implant system incorporating the interface madel were compared to the results of mechanical tests performed on similar implants which had resided in canines for two yr. The resutts fram the finite elernent analysts using the interface model were found to be in better agreement with the experimental results than when a direct bone- to-porous-inaterial interface was assumed.

Published: November 2010

Coralline replamineform hydroxyapatite implants were placed in canine subcutaneous tissues in an attempt to clarify whether the hydroxyapatite matrix acted as a passive matrix for osseous ingrowth when placed in same inherent bone induction capacity. The implants were well-tolerated and elicited no deleterious host response. Connective tissue rapidly infiltrated the pores, but no evidence of hone formatian was noted in any of the specimens. It was concluded that this implant material does not act to induce bone formation.

Authors: Ohno H. , Kanzawa Y. , Kawashima I. , Shiokawa N. 
Published: November 2010

Changes in the morphology of the oxidation zone and the quantities of oxide for gold alloys containing two base metals (In and Sn) were investigated by exposing alloys at 1000°C for one h in air. The contents of In and Sn were varied in the range of from 0-1.5 wt%. In the range of from 1.5-0,35 wt% In (from 0-1.15 wt% Sn), In2 O3 was formed predominantly at the alloy surface. The electron probe x-ray micro-analyzer detected no uniform external oxidation zone. A mixture composed of In2O3 and SnO2 precipitated internally in the alloy matrix. An external oxidation zone composed of SnO2 was formed on the alloys containing over 1.2 wt% Sn, and no internal oxidation zone was observed.
Tissue Repair After Condylectomy in Growing Macaca fascicularis
Authors: Bakker V.M. , Swartberg P.E. , Heeley J.D. 
Published: November 2010

In order to determine the nature of tissue repair after removal of condyles, bilateral condylectomies were performed in seven growing female Macaca fascicularis. Two animals underwent condylectomies only, and five animals were fitted with maxillary and mandibular splints before undergoing condylectomies. One condyle from each condylectomized animal was processed for histologic examination. Four animals, with intact condyles, were available as controls: Two had splints placed, while the other two did not undergo any treatment. Nine mo after surgery, the histology of 12 resection sites and 12 control condyles (seven removed at condylectomy and five at death) was compared. In the control condyles, hypertrophic cartilage was seen over the entire condylar surface. From the 12 resection sites, five showed hypertrophic cartilage, non-hypertrophic cartilage cells were present in three, and four demonstrated bone apposition and resorption. Cartilage was present only at the medial and central aspects of the surgical site, and in every specimen, bone was seen at the lateral pole. Two out of 12 fossae overlying surgical sites contained hypertrophic cartilage, while the five control glenoid fossae showed bone, an intermediate zone, and a fibrous capsule. Because of the variety in tissue response and the small number of animals in each group, the effect of the splints could not be determined. Based on the results of this study, the following was concluded: (1) Regeneration of organized hypertrophic cartilage with inherent growth potential can take place after condylectomy, albeit not in every instance and only in the medial aspect of the stump. In the lateral aspect, and also medially if hypertrophic cartilage does not reform, bone is predominant. The original height is not recovered. (2) The cartilage of the glenoid fossa is capable of adaptive changes similar to those seen in condylar cartilage.
Basic Biological Sciences Relationship between Concentration of Human Salivary Statherin and Inhibition of Calcium Phosphate Precipitation in Stimulated Human Parotid Saliva
Authors: Hay D.I. , Smith D.J. , Schluckebier S.K. , Moreno E.C. 
Published: November 2010

Human salivary secretions are supersaturated with respect to the calcium phosphate salts which form dental enamel, a property which provides important protection for the teeth. We previously proposed that statherin, a 43-residue phosphopeptide, plays a key role in this protective system by inhibiting or delaying potentially harmful precipitation of calcium phosphate salts in the salivary glands and mouth. The purpose of the present study was to determine if the concentrations of statherin in saliva, despite their wide normal range, are high enough to fulfill this function. Concentrations of statherin in stimulated human parotid saliva samples from 36 female and 32 male subjects, aged from 17 to 30 years, were determined by a single radial immunodiffusion method. Values found ranged from 3.0 to >27.3 μM, with a mean value of 12.8 (S.D. ± 5.46) μM. At concentrations below these values, statherin inhibited spontaneous precipitation of calcium phosphate salts from an assay system which was more supersaturated with respect to dicalcium phosphate dihydrate, and comparably supersaturated with respect to hydroxyapatite, than were human saliva samples. The inhibitory activities of five of the 65 stimulated parotid saliva samples assayed were greater than would be anticipated from their statherin concentrations. This unexplained discrepancy is not associated with the presence of the acidic proline-rich proteins in saliva, although these proteins also affect calcium phosphate precipitation. The results of this study show that statherin is present in stimulated human parotid saliva at concentrations and levels of activity which are consistent with its proposed biological function, and support the proposal that statherin plays a significant role in a system which provides a protective and reparative but stable environment for the teeth.
