Abstract

This paper is concerned with materials formed by polymers containing ionic or ionizable groups in their chemical repeating units (polyelectrolytes) which have been of interest in the area of biomaterials over the past two decades. Presently, two largely polyelectrolytic compositions are utilized as dental cements or as restorative materials for hard oral tissues. Results of an experimental study are presented which show that considerable variations in ionization rates of polyelectrolytes through acid/base reactions exist among different dental biomaterials in use at the present time. These variations could result in different degrees of ionic crosslinking which is related to mechanical strength and hydrolytic stability of the set product. Based on model studies on adsorption, further investigations on the role of ionization kinetics on long-term properties are suggested for the purpose of optimizing both adhesion and bulk properties of polyelectrolyte-based bio-materials.
