Aim: To study the evaluation of the combined effect of Diode laser and fluoride gel on root dentin demineralization and compare between the use of laser only & laser with fluoride in root caries.
Methods: Tooth preparation & grouping, fluoride treatment, laser treatment, fluoride & laser treatment, tooth-sectioning and artificial caries application & environmental scanning electron microscope analysis.
Results: The effect of artificial caries on the fluoride and diode laser specimens showed an augmentation of the caries prevention mechanism.
Conclusion: Our results strongly dictate a synergistic rather than an additive effect of the combined diode laser and fluoride gel treatments in root caries inhibition.
