This study compares sensitivity reduction after dental restoration with and without prior diode laser (DL) irradiation for cervical dentine hypersensitivity (CDH) from non-carious cervical lesions (NCCLs) unresponsive to desensitizing agents. Eighty-eight teeth of 28 subjects (21 females; age 23–64 years), with CDH from NCCL were included in this study. NCCLs of each oral quadrant were randomized in two groups (study group (SG)) to estimate the sensitivity reduction after dental restoration (SG-1) compared with the DL irradiation used prior to restoration placement (SG-2). The subjects were asked to rate the sensitivity experienced during air stimulation using a visual analog scale before (baseline), immediately after, and at 6 and 12 months from restoration. The outcomes showed a significant reduction of discomfort compared to baseline for NCCLs of SG-2 with the decrease of 78.5, 78.9, and 78.1 % immediately and at 6 and 12 months after restoration, respectively; in comparison with the decrease of 70.1, 67, and 65.3 % for NCCLs of SG-1 immediately and at 6 and 12 months after restoration, respectively; and compared to baseline. The DL irradiation prior to dental restoration can further improve the painful symptomatology of CDH from NCCL unresponsive to desensitizing agents.
