The aim of this study was to investigate the effectiveness of low-level laser therapy (LLLT) on tooth sensitivity post-in-office bleaching. Sixty patients were selected for a randomised clinical trial. After the in-office bleaching procedures with 38 % hydrogen peroxide, the participants were randomly divided into two groups of 30 subjects each. In LLLT group, patients received LLLT through an 810 nm diode laser with 0.5W for 30 sec at a density of 15 J/ cm2, while participants in the placebo group were subjected to an LLLT with similar conditions but without any energy output. The intensity of tooth sensitivity was recorded at 1, 24, and 48 h after bleaching using a visual analogue scale (VAS). The intensity of tooth sensitivity was not significantly different between groups at 1h after bleaching (p=0.593). At 24 h and 48 h after the bleaching procedure, the pain level was significantly lower in the LLLT group compared to the placebo groups (p < 0.0001). The LLLT with a diode laser could be used as a suitable strategy to reduce the intensity of tooth sensitivity after in-office bleaching.

Abstract
The aim of this study was to investigate the effectiveness of low-level laser therapy (LLLT) on tooth sensitivity post-in-office bleaching. Sixty patients were selected for a randomised clinical trial. After the in-office bleaching procedures with 38 % hydrogen peroxide, the participants were randomly divided into two groups of 30 subjects each. In LLLT group, patients received LLLT through an 810 nm diode laser with 0.5W for 30 sec at a density of 15 J/ cm2, while participants in the placebo group were subjected to an LLLT with similar conditions but without any energy output. The intensity of tooth sensitivity was recorded at 1, 24, and 48 h after bleaching using a visual analogue scale (VAS). The intensity of tooth sensitivity was not significantly different between groups at 1h after bleaching (p=0.593). At 24 h and 48 h after the bleaching procedure, the pain level was significantly lower in the LLLT group compared to the placebo groups (p < 0.0001). The LLLT with a diode laser could be used as a suitable strategy to reduce the intensity of tooth sensitivity after in-office bleaching.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
