Some electrical properties , such as piezoelectricity, ac conductivity, dielectric constant and loss tangent of
nine commercial types of dental composite restorative materials, have been investigated before and after laser
exposure for 3s to study the effect of a probable laser exposure during some surgeries on the electrical
properties of these materials . No piezoelectric effect has been found in these materials before and after laser
exposure. The materials were found to be good insulators (very poorly conducting materials ). The temperature
and frequency dependence of ac conductivity, dielectric constant and loss tangent have not shown significant
changes in values after laser exposure. |
