Dentin Hypersensitivity - Varnish or Laser?
- Conditions
- Dentin Hypersensitivity
- Interventions
- Device: Laser Irradiation
- Registration Number
- NCT06539286
- Lead Sponsor
- Sigmund Freud PrivatUniversitat
- Brief Summary
Dentin hypersensitivity is a common condition described as a short and sharp pain caused by thermal, evaporative, tactile, osmotic, or chemical stimuli to exposed dentin that cannot be related to another defect or dental pathology. The variety of treatment options and products on the market might seem overwhelming. This study aims to show that laser treatments are efficient in reducing pain scores compared to a desensitizing agent (Gluma). 80 patients with at least two hypersensitive teeth will be enrolled in this study. Patients will be divided randomly into four groups (control group (Gluma), laser group 1 (2.94 µm wavelength), laser group 2 (1064 nm wavelength), laser group 3 (970 nm wavelength)). Visual Analog Scale will be measured before treatment, right after treatment, one week after treatment, one month after treatment, three months after treatment. Mixed Anova's and descriptive analysis will be used for statistical evaluation.
- Detailed Description
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.
