Background: Vital bleaching is most requested cosmetic dental procedure asked by patients who seek pleasing smile. Laser helps to reduce the stain and helps in teeth whitening. Aim: To investigate the effect of laser therapy induced by teeth bleaching. Methodology: A Literature review was performed using PubMed, Medline, PMC, Grey literature, Cochrane, Prospero, Wiley online library using MeSH term laser and teeth bleaching. Of a total 1658 appeared from various sources; all articles were screened and 14 were related to the research question and 5 were selected for the study. This review was reported according to PRISMA guidelines. Result: In the five studies of our systematic review shows that laser used in the case of teeth bleaching with higher concentration of hydrogen peroxide produced better result and comparatively lesser sensitivity than any other bleaching agents or lesser concentration of hydrogen peroxide. Conclusion: Clinical trials suggests that laser used in bleaching the tooth has better efficacy on tooth surface which resulted in lesser sensitivity and better tooth color, at the same time effectiveness of the treatment is same as that of the normal procedure.

“…The outcomes of this study are consistent with the results of Gurgan et al (Gurgan et al 2010) who found that bleaching with a diode laser was associated with less tooth and gingival sensitivity, and so this method might be preferred among the in-office systems. In contrast, some studies found that laseractivated bleaching had no effect on or even increased postoperative dental sensitivity (Farhat et al 2014;Giudice et al 2016).…”

This study aimed to evaluate the efficacy and complications of several bleaching methods in patients with discolored teeth after orthodontic treatment. This randomized clinical trial involved 60 volunteers (31 women, 29 men) aged 14 to30 years, who finished fixed orthodontic therapy at least three months before the study commencement and complained of discoloration on upper front teeth. The subjects were divided into four groups by treatment. The patients in group 1 received home bleaching, whereas those in groups 2 to 4 underwent in-office bleaching using a diode laser, a plasma arc and no light source, respectively. Tooth color was measured at baseline, one hour after the end of the bleach- ing procedure, and one week later, and the color alteration between different stages was com- pared among the groups. The severity of tooth sensitivity and the occurrence of other post-treatment complications were recorded. The color change between baseline and one week after treatment was greatest in the home- bleaching and the laser-assisted bleaching groups, and lowest in the plasma-arc bleaching group, although the difference between the groups was not significant (p > 0.05). Tooth sensitivity over 24 hours after bleaching was lowest in subjects who had undergone laser-assisted bleaching and highest in those who had received in-office bleaching without light (p < 0.05). All methods were effective in managing tooth dis- coloration after orthodontic treatment. Home bleaching produced favorable color alteration. Amongst the in-office approaches, laser-assisted bleaching should be considered as the best option, as it produced effective results with lowest tooth sensitivity and over a shorter period of time.

“…In theory, the light source, by energizing hydrogen peroxide (H 2 O 2 ), increases the rate of oxygen decomposition, accelerates the release of reactive oxygen species, and thus enhances the breakdown of carbon double bonds present in the chromophores of the teeth [1]. Although it is a highly popular technique in dental practice, it raises some concerns, particularly regarding the adverse effect of dental sensitivity [2][3][4][5].…”

“…Factors such as the concentration of the gel and the application protocol in uence the intensity of this exposure and subsequent damage [12][13][14]. The use of LED light sources has also been associated with sensitivity [1,15], increased pulp temperature [1,5,16], and appears to have no signi cant improvement in color effectiveness [13,[16][17][18]. Therefore, it is important to evaluate the biological repercussions that this treatment modality may have on the pulp tissue.…”

Objective: The main purpose of this study is to evaluate the effect of dental bleaching with 460 nm LED light on pulp tissue by assessing pulp oxygen saturation (SaO2) and dental sensitivity in different dental groups and follow-up times. Materials and Methods: This study is a randomized clinical trial using a split-mouth design. SaO2 levels were measured using a pulse oximeter adapted for dentistry, and dental sensitivity was assessed using the visual analog scale on 600 intact anterior teeth. Fifty volunteers were selected, and their upper dental arches were randomly divided into two halves (right and left) to create two groups. G1 - half arch that received LED activation to activate the bleaching agent for 1 minute at each gel change, totaling 3 minutes of activation; and G2 - half arch where LED was not used to activate 35% hydrogen peroxide. SaO2 levels were analyzed before bleaching (T0), immediately after the first session (T1), on the seventh day of treatment (T2), 30 days (T3), 6 months (T4), and 1 year (T5) after dental bleaching. Sensitivity testing was conducted until T3. The data were analyzed using the Shapiro-Wilk test for normality, independent samples t-test to evaluate differences between groups, and repeated measures ANOVA with Tukey's multiple comparisons test to assess variability over time. The significance level was set at 5%. Results: An increase in SaO2 was observed in the upper central incisors immediately after light application, followed by a reduction after 24 hours (P < 0.05), and stabilization at subsequent time points (P > 0.05). For both dental arches, the quadrants that received light during bleaching exhibited higher sensitivity to stimuli immediately after treatment (P < 0.05). Conclusions: Dental bleaching with 460 nm LED light increases SaO2 and dental sensitivity immediately after the procedure in the upper central incisors. However, these changes are reversible after 24 hours. Clinical relevance: The clinical significance of the study lies in the potential for increased oxygen saturation levels and dental sensitivity following dental bleaching with 35% hydrogen peroxide in conjunction with the use of an LED light.
