The effectiveness of current dentin desensitizing agents used to treat dental hypersensitivity: A systematic review

Objective: Dentin desensitizing agents are used in the treatment of dentin hypersensitivity, which is defined as a painful response in the exposed dentin to stimuli that are thermal, evaporative, tactile, osmotic, or chemical. A systematic review was conducted to analyze the clinical effectiveness of current desensitizer with at least 3 months of follow-up. Method and Materials: Eight electronic databases were searched: MedLine (PubMed), Embase, Lilacs, Ibecs, Web of Science, Scopus, Scielo, and The Cochrane Library. Only those clinical trials published from 2000 to 2012 were included. Results: A total of 3,029 relevant records were identified. After title and abstract examination, 2,645 articles were excluded. A data extraction form was designed and completed by reviewers from the selected studies for a retrospective comparison. From the 99 studies retrieved for detailed review, only 17 had an evaluation time of at least 3-months follow-up and fulfilled the selection criteria. Conclusion: Cervitec Plus, SE Bond & Protect Liner F, laser, and iontophoresis have shown satisfactory posttreatment results between 3 and 6 months. However, additional clinical trials are warranted to better compare the different types of treatments and their effectiveness in the longer term.
