Comparative Evaluation of Efficacy of Diode Laser and Clinpro XT Varnish for Treatment of Dentin Hypersensitivity: A Randomized Clinical Trial.

Context: Dentin hypersensitivity (DH) is a very common dilemma and often results in temporary relief by the conventional treatment method. An in vivo comparative study of various methods and materials helps in evaluation of a superior method to provide a long-lasting relief.

Aim: The aim of this study was to evaluate the efficacy of diode laser (DL) and Clinpro XT Varnish for managing DH.

Materials and methods: This study was a randomized, single-blinded, clinical trial, designed, adhering to the CONSORT (Consolidated Standards of Reporting Trials) Guidelines using DL and fluoride-based varnish for managing DH. A total of 40 teeth were selected from eight patients and randomly divided into two groups. All patients received tactile and air syringe stimulus to assess for DH and a visual analog scale (VAS) was used to obtain readings at baseline, 15min, 1 week, and 3 weeks, posttreatment. Student's t test was used, paired t test was for the intragroups, and unpaired t test was for intergroups.

Results: This study showed that the effect of DL and Clinpro XT Varnish results in a significant decrease of DH. However, success decreased gradually over time.

Conclusion: Clinpro XT Varnish presented superior immediate effect and DL effect tends to become better with time. Hence, both had good results in the end.
