Dental Adhesion With Self-Etching, Polymerization-Initiating Primers

October 16, 2008
Author(s)
Joseph M. Antonucci, C A. Khatri, Gary E. Schumacher, J E. Code, T Nikaido
Iminoacetic acids are noted for their moderate acidity and ability to chelate metal ions, including the biologically important calcium ion. Previously it was shown that the application of N-phenyliminodiacetic acid (PIDAA) both etches and activates

Research for Improved Dental Restorative Materials

October 16, 2008
Author(s)
Francis W. Wang, Joseph M. Antonucci, J W. Stansbury
In Part A of this report, the interfacial bonding between resin and filler in dental composites is probed by use of the microdrop bead test in a single fiber model study. The microbond test has been shown to be a useful method for comparing silane treated

Shear Bond Strength of Bioactive Amorphous Calcium Phosphate Composites

November 1, 2007
Author(s)
Gary E. Schumacher, Joseph M. Antonucci, Justin N. O'Donnell, Drago Skrtic
Bioactive, amorphous calcium phosphate (ACP)-filled polymeric composites in aqueous environments release significant amounts of Ca and PO4 ions leading to deposition of an apatitic mineral that is similar to that found in enamel. These materials are

Structure/Property Relationships in Urethane Dimethacrylate-Based ACP Composites

April 26, 2006
Author(s)
William Regnault, Tonya Icenogle, Joseph M. Antonucci, Da-Wei Liu, Drago Skrtic
In this study, the effects of two comonomers (the low molecular mass, hydrophilic 2-hydroxyethyl methacrylate (HEMA) vs. the high molecular mass, less hydrophilic, more flexible polyethyleneglycol extended UDMA (PEG-U)) on the PS, PSD and DC were assessed

Amorphous Calcium Phophate Composites With Improved Mechanical Properties

January 1, 2006
Author(s)
Justin N. O'Donnell, Joseph M. Antonucci, Drago Skrtic
Young s Modulus, diametral tensile strength and water sorption. Mechanically milling the filler increased the volume of fine particles in the sample, resulting in a more homogeneous intra-composite distribution of ACP and a reduction in voids. In turn

Ethoxylated Bisphenol Dimethacrylate-Based Amorphous Calcium Phosphate Composites

January 1, 2006
Author(s)
Drago Skrtic, Joseph M. Antonucci, D W. Liu
Improving the anti-demineralizing/remineralizing and mechanical properties of amorphous calcium phosphate composites has been the focus of our recent research. In this study an ethoxylated bisphenol A dimethacrylate (EBPADMA) was blended with triethylene

Chemistry of Silanes Interfaces in Dental Polymers and Composites

September 1, 2005
Author(s)
Joseph M. Antonucci, Sabine H. Dickens, Bruce O. Fowler, Hockin D. Xu, Walter G. McDonough
The performance and service life of glassor ceramic-filled polymeric composites depend on the nature of their resin, filler and interfacial phases as well as the efficacy of the polymerization process. The synergy that exists between the organic polymer

Improved Dental Composites Utilizing Dibenzylidene Sorbitol Networks

July 1, 2005
Author(s)
Elizabeth Wilder, Joseph M. Antonucci
Dibenzylidene sorbitol (DBS) is a sugar derivative that is capable of self-organizing into a 3D nanofibrillar network at relatively low concentrations in a wide variety of organic solvents and polymer melts. This research was aimed at determining the

Effect of an Organogelator on the Properties of Dental Composites

May 1, 2005
Author(s)
Elizabeth Wilder, K S. Wilson, Janet Quinn, Drago Skrtic, Joseph M. Antonucci
Bioactive dental composites containing amorphous calcium phosphate have the potential to remineralize caries lesions and white spots, but their applications are limited by the inherent weakness of calcium phosphate as a filler material. In order to extend

In Vitro Cytotoxicity of Amorphous Calcium Phosphate Composites

May 1, 2005
Author(s)
Carl Simon Jr., Joseph M. Antonucci, D W. Liu, Drago Skrtic
Calcium phosphate-based biomaterials are being widely used as bone substitutes in dentistry as well as reconstructive and orthopedic surgery because of their generally accepted good biocompatibility, osteoconductivity and/or bone-bonding properties. Among
