Effect of Laser and Fluoride Application for Remineralization of the Carious Lesion: A Polarized Microscopic Study
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 2
Abstract
Introduction: The new philosophy of prevention rather than repair and replacement has led to the emergence of new era of preventive dentistry. Fluoride is the most widely applied method of caries prevention that remineralizes the subsurface carious enamel. Lasers have been recently investigated as an alternative for caries prevention and enhances the enamel’s resistance to acids. So the present study has been carried out in an attempt to explore the possibilities of the effects and applications of Laser in Preventive Dentistry. Study aimed to evaluate the effect of laser irradiation followed by fluoride application alone on remineralization of deciduous teeth. Material and Methods: 30 deciduous extracted molars were randomly divided into 3 groups and were kept in demineralizing solution for 48 hours and then were exposed to remineralizing reagents of their respective groups. In the first group the demineralized teeth were coated with fluoride varnish for 5 min, the second group teeth were irradiated with laser for 10 sec and the third group teeth were first irradiated with laser for 10 sec and then coated with fluoride varnish and left for 5 min and then all the teeth were immersed in artificial saliva and the 3 remineralizing cycle was performed. The sections were prepared mesio-diastally and observed under polarized microscope. Result: The images under polarized microscope showed that the area of demineralization zone was drastically reduced in the specimen irradiated with laser and with laser followed by fluoride varnish application as compared to that of fluoride varnish alone. Conclusion: All the applied treatments were capable of reducing caries progression in dental caries amongst which laser irradiation in adjunct to fluoride application was most effective.
