Abstract

A method has been described to temporarily restore an anterior edentulous space in a single appointment. The technique uses a composite resin to retain a resin denture tooth (pontic) supported by edgewise orthodontic wire. This approach is suggested as a transitional treatment for patients who are not amenable to either a definitive fixed or removable prosthesis.

Thermographic measurement of temperature change during resin composite polymerization in vivo.

OBJECTIVES: To use the technique of infrared thermography for non-invasive monitoring of temperature changes during polymerization of resin composite by measuring the infra-red emission from the surfaces of resin composite restorations during photocuring. METHODS: In this study 10 patient volunteers had resin composite restorations placed in upper incisor teeth and during photocuring the temperature rise within the composite was measured using the Thermovision 900 infra-red scanning system. RESULTS: The results demonstrate that the exotherm is almost instantaneous, occurring as soon as the light source is activated and rising to a peak at approximately 30 s before levelling off. The measurements suggest that a maximum temperature increase of 12 degrees C could occur, although this may only be for a short period (< 15 s). CONCLUSION: The range of temperature rise measured in this study (mean 5.4 degree C +/- 2.5 degree C) would suggest that the pulp may be endangered by the temperature rise which occurs during resin composite polymerization in vivo.
