Efficacy of fluoride varnish for the treatment of dentin hypersensitivity

According to a recent study, Single Bond Universal, Xeno V+ (seventh-generation dentin bonding agents), and Bifluorid 12 exhibit equal effectiveness in reducing dentin hypersensitivity (DH), with no clear superiority observed over a one-month period. These findings underscore the potential of fluoride varnishes as a cost-effective and less technique-sensitive treatment option for DH. This study’s results were published in the BMC Oral Health.

In this parallel-group, single-center, double-blind, controlled randomized clinical trial, a total of 105 patients with DH were included. The patients were divided into three groups: one group received Single Bond Universal by 3 M ESPE, another group received Xeno-V+ by Dentsply, and the control group received fluoride varnish (Bifluorid 12 by Voco). This study assessed the Discomfort Interval Scale scores and Schiff Cold Air Sensitivity Scale scores at baseline, immediately after the treatment, after 1 week, and after 1 month.

Treatment with all the materials demonstrated a significant reduction in discomfort and sensitivity (DIS scores p-value 0.01) observed immediately after one week and sustained over one month compared to baseline scores. None of the materials showed superiority during the one-month observation period. The study also provided insights into dental hygiene practices, indicating that the majority of participants used a toothbrush. Cold stimuli were identified as the most prevalent cause of sensitivity.

The above study demonstrated that Single Bond Universal, Xeno V+, and Bifluorid 12 are equally effective in reducing dentin hypersensitivity for one month. These results underscore the potential of fluoride varnishes as a cost-effective and less technique-sensitive treatment option for DH.
