Potassium Nitrate Gel and Diode Laser for Dentinal Hypersensitivity

Participants in the experimental group receive treatment combining a desensitizing gel containing 5% potassium nitrate (Emoform Actisens) applied to affected teeth and diode laser therapy (980 nm). The laser is used with specific power settings (0.3W, 0.5W, 0.7W) for 20 seconds at each setting, followed by a second application of the gel and irradiation. The treatment aims to reduce dentinal hypersensitivity by occluding dentinal tubules and altering neural responses.

Participants in the control group receive treatment with a desensitizing gel containing 5% potassium nitrate (Emoform Actisens) applied to the teeth. The gel is applied twice using a microbrush in a rubbing motion for 2 minutes each time. No diode laser therapy is administered. This intervention aims to evaluate the standalone efficacy of the gel in reducing dentinal hypersensitivity.
