“…Some of these studies are specifically directed to the thermal diffusivity of restored teeth (Braden, 1964;Augsburger and Peters, 1981;Peters and Augsburger, 1981a;Tibbetts et al, 1976;Peters and Augsburger, 1981b). Braden (1964) showed, in an in vitro study concerning thermal diffusivity in restored teeth, that the thickness of a cement base is of more importance than its composition.…”

Using the finite element method, we analyzed the temperature distribution and heat flow patterns in an axisymmetric tooth model. The models of an unrestored tooth and three teeth restored with different restorative materials were evaluated comparatively. The insulating ability of a calcium hydroxide cement base (Ca(OH)2) is low, which is inherent in its insufficient thermal and poor mechanical properties. In the given conditions, the Ca(OH)2 base reduces the temperature increase at the cement-dentin interface by 12.5% with respect to a restoration of amalgam only. By using a double base (Ca(OH)2 + polymer-modified zinc oxide-eugenol), the reduction is 21.9%. With respect to a sound tooth model, the presence of a double base in the restored tooth caused a temperature increase of only 0.1 degree C at the pulpo-dentinal junction. The thermal conductivity coefficient (lambda) of amalgam does not have any influence on the results of the calculations. The heat transfer coefficient (alpha) turned out to be an essential parameter in this mathematical model.

“…8 Trowbridge and others 1 1 also resected the roots from teeth in an experiment in which the speed of temperature transference was evaluated. Their method of maintaining teeth at body temperature differed in that a water bath at 34 0 C was used.…”

“…The CO 2 pencil,+ shown previously to be fast, accurate and consistent, was used for testing 16 (Fig 3). As a control prior to making the cavity preparations, each tooth was tested and the enamel plus dentin thickness recorded ( Table 1, Fig 4).…”
