Abstract
A method is disclosed for monitoring the curing status of a dental resin through the inherent fluorescence of the dental resin under a curing light. The method requires no sample preparation and is fast enough for real time cure monitoring.
Claims5
A method for monitoring the polymerization status of a dental composite resin, the method comprising the steps of:
- causing a light beam to be incident on the dental resin, the light beam having a wavelength selected to cure the dental resin and to excite inherent fluorescence emission from said dental resin;
- measuring a spectrum of said fluorescence emission in real time;
- and
- obtaining polymerization status information regarding the curing process from the measured fluorescence spectrum.
