Suppression of root caries progression by application of Nanoseal®: A single-blind randomized clinical trial.

The aim of this single-blind, parallel and randomized controlled trial was to evaluate the effect of Nanoseal® application on root caries progression. Adult patients (n=129, mean age: 66.4±10.1 years) with root caries were randomly allocated into three groups: high-frequency (HF, n=43; intervention: Nanoseal application at baseline and 1-5 months), low-frequency (LF, n=43; intervention: Nanoseal application at baseline and 3 months), and control (n=43; intervention: no application of Nanoseal) groups. Measurements of fluorescence laser values of carious lesions using a DIAGNOdent™ Pen (D-value) were performed for each subject before intervention (baseline) and at 3 and 6 months. Significantly lower D-values for the HF (p=0.017) and LF (p=0.034) groups were observed compared with the control group at 6 months. Nanoseal application would be an effective procedure to suppress root caries progression.
