Title Nd:YAG Laser Treatment for Dentin Hypersensitivity in Adults is Possibly More Effective Than Potassium Nitrate-Containing Toothpastes
Clinical Question Adult patients often complain of teeth sensitivity due to exposed dentin, so is Nd:YAG laser a more effective desensitizing treatment than potassium nitrate-containing toothpastes?
Clinical Bottom Line Treating dentin hypersensitivity with Nd:YAG laser may be more effective than potassium nitrate-containing toothpastes, however, more research is required. (See Comments on the CAT below)

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 11034117Kimura/2000Review of articles from 1985 to 1999Non-systematic Review
Key resultsNd:YAG laser is more effective (effectiveness ranged from 51.5% to 100%) for treating dentin hypersensitivity than other methods, but less effective in severe cases.
Evidence Search Pubmed search using these terms: "Dentin Sensitivity"[Mesh] AND "Lasers"[Mesh]; "Dentin Sensitivity"[Mesh] AND “Potassium nitrate” [Mesh]
Comments on
The Evidence
The authors did not indicate clear searching methods and studies selection, nor did they specify the number of articles reviewed, and no meta-analysis was done. Also, the article stated that laser treatment was more effective than “other methods”, but it did not specify those methods. The patient pool is unknown. However, a Cochrane Systematic Review, Poulsen (2008, PMID 16855970), on potassium nitrate-containing toothpaste concluded that “no clear evidence is available for the support of potassium containing toothpastes for dentine hypersensitivity”.
Applicability For adult patients with hypersensitive dentin.

A PubMed search of MeSH terms "Dentin Sensitivity" AND "Lasers" was repeated on this day 1/7/2013. We found a more recent publication PubMed ID 21223353. This systematic review supports the CAT conclusion that lasers have a small clinical advantage over topical medications, but calls for further RCTs on the topic.
