The Desensitizing Treatment Effects of the Laser and Ozone on Dentin Hypersensitivity: In-vivo Comparison

The Desensitizing Treatment Effects of the Laser and Ozone on Dentin Hypersensitivity: In-vivo Comparison

The goal of this split mouth clinical trial is to compare clinical efficacy of diode laser and gas ozone in the treatment of dentine hypersensitivity (DHS) of non-carious-cervical lesion. The main questions it aims to answer are:

• gas ozone affects dentine hypersensitivity?
• diode laser affects dentine hypersensitivity? Participants, affected of DHS , were treated with gas ozone and diode laser.The pain severity was quantified according to the Visual Analogue Scale (VAS) before and after the treatmens.

Inclusion Criteria:

• Stimulated dentine hypersensitivity greater than 6 on visual analogue scale (VAS)
• DHS affected two teeth, not contiguous, of different mouth semiarch.

Exclusion Criteria:

• Periodontal surgery in the last 3 month
• Use of desensitizing paste in the last 3 month
• Pregnant or breastfeeding state
• Teeth with caries, reconstructions, pulpits congenital anomalies, fracture, and occlusal interferences.
