Laser-assisted treatment of dentinal hypersensitivity : a literature review

The purpose of this literature review was to evalu- ate the effectiveness of the laser-assisted treat- ment of dentinal hypersensitivity. A review with inclusion and exclusion criteria was performed from January 2009 to December 2014 with elec- tronic data-bases: MedLine via PubMed, Science Direct and Cochrane Library. Research of paper magazines by hand was not considered. Forty- three articles were selected between literature re- views, in vitro studies, clinical trials, pilot and preliminary studies. The items were divided into laser-used groups for an accurate description, and then the reading of results into various ty- pologies. Laser-assisted treatment reduces denti- nal hypersensitivity-related pain, but also a psy- chosomatic component must be considered, so further studies and more suitable follow-ups are necessary
