Primary Outcome Measures

To Clinically Assess Change in Dentin Hypersensitivity Between Baseline and After Exposure to Diode Laser Radiation.
Dentin Hypersensitivity is Determined using Cold Stimulus. Utilizing Visual Analog Scale (VAS) Reading 0-10 Where 0 is No Pain, While 10 is the Most Experienced Pain.

5. Study Description

Brief Summary
This study will investigate the efficacy of three diode laser wavelengths 445 nm, 660 nm, 970 nm when applied just before placement of composite restoration on reducing postoperative sensitivity from Non-carious cervical lesions (NCCLs) with class V cavity preparation.
Detailed Description
In this randomized clinical trial, patients with NCCLs will be included (four teeth in each participant). After class V cavity preparation in the NCCLs, the teeth will be randomly assigned into four groups according to diode laser irradiation wavelength Group 1 (placebo) laser simulation and Group 2 (445 nm) diode laser wavelength, Group 3 (660 nm) diode laser wavelength, and Group 4 (970 nm) diode laser wavelength. Following laser irradiation, the universal self-etch adhesive will be applied and all the cavities will be restored with the same resin composite. Tooth sensitivity to a cold stimulus will be recorded using a visual analogue scale (VAS) before treatment and on follow-up days 1, 14 followed by 1, 3, and 6 month after treatment.

Model Description
In this randomized controlled clinical trial, patients with NCCLs will be included (four teeth in each participant). The teeth will be randomly assigned into four groups according to diode laser irradiation wavelength Group 1 (placebo) laser simulation, Group 2 (445 nm) diode laser wavelength, Group 3 (660 nm) diode laser wavelength, and Group 4 (970 nm) diode laser wavelength.
Masking
ParticipantInvestigatorOutcomes Assessor
Masking Description
The allocation will be hidden from patients, and they will not know which teeth are lased and which will receive the placebo treatment. In addition, for blinding, the restoration procedure is performed by one person, and the cold test is performed by another person who is unaware of the distribution. Furthermore, the statistician will be blinded.
