Aim: This review was undertaken to evaluate the efficacy of light activation on in-office dental bleaching in terms of color change and photosensitivity with available literature evidence.
Materials and methods: The articles were searched from MEDLINE/Pubmed and Journal of Web, which were published from 2001 to 2019.
Results: Out of the 124 references obtained, 13 articles in English language were read in full, which fulfilled the inclusion criteria.
Conclusion: Light activation of hydrogen peroxide on in-office dental bleaching does not affect effectiveness of bleach.
Clinical significance: Though claimed that in-office bleaching activated with light betters color change, the present review did not confirm this belief.
