Dentin Hypersensitivity - Varnish or Laser?

A total of 80 patients meeting the inclusion criteria will be included in this randomized clinical study. Participants will be randomly divided into four groups. Pain scores will be measured before treatment, right after treatment, 1 month after treatment and 3 months after treatment using the Visual Analog Scala (VAS). Patients will not know which treatment will be performed before nor will the patients from the laser groups know the wavelengths. Pain scores at check-up meetings will be collected by another doctor other than the one who will perform all laser treatments.
