Abstract

Introduction: Root caries is a problem of increasing importance in the dentate patients. Which could be arrested in early stages, obviating restorative therapy. Different chemotherapeutic strategies (antimicrobial rinses, fluoride solutions and amorphous calcium phosphate) have demonstrated success in this regard. Photoactivated disinfection(PAD) is an effective method in which cytotoxic reactive oxygen is liberated when activated by light of a specific wavelength. It is a selective technique which could be used in several oral applications.

Aim of the study: The aim of present study was to evaluate the effect of PAD and chemotherapeutic materials application on initial root caries. Methods:50 initial root lesion in adult patient were selected in this study. Diagnodent measurements were used as a scale for samples selection. Samples divided in two groups. First 25 patient had no treatment as control group. In second group PAD protocol was used by

application of 12.7 mg/L Tolonium chloride and irradia-tion of 635 nm diode laser (8 J/cm²). Samples received a CPP-ACP application after PAD therapy. Diagnodent measurements were performed at days 1, 7 , 14 ,21 after treatment.

Results:There was no significant change in Diagnodent values in control group during study(P>0.05). Diagnodent values in second group were significantly lower after day 14 and 21 (P<0.05).

Conclusion: PAD and fluoride therapy could be an effective method in arresting initial root caries.
