Vital laser-activated teeth bleaching and postoperative sensitivity: A systematic review

Amira Kikly et al. J Esthet Restor Dent. 2019 Sep.

Abstract

Objective: This systematic review investigated the effect of vital laser-activated tooth bleaching regarding efficiency and postoperative sensitivity. The search for articles was conducted on Medline (PubMed) database. The following keywords were used: "Lasers" [Mesh] and "Tooth bleaching" [Mesh]. Using the Boolean operator "AND," the following Boolean equation was formulated: ("Lasers" [MeSH] AND "Tooth bleaching" [MeSH]).

Materials and methods: Inclusion criteria were as follow: clinical trials in English or French available in full text. Article search was limited to the ones published between 2007 and 2019.

Results: A total of 12 articles fulfilled the inclusion criteria. The quality assessment of trials included was undertaken independently as part of data extraction process. A JADAD score was attributed to each paper.

Conclusion: A marked color change was noted for patients undergoing light-activated bleaching independently of the bleaching agent. Regarding sensitivity, the results of the various studies proved controversial.

Clinical significance: Laser activation of the bleaching agent promotes the efficiency of the treatment but does not reduce postoperative sensitivity.

Keywords: dentin sensitivity; efficiency; lasers; systematic review [publication type]; tooth bleaching.
