Parameters Used With Diode Lasers (808-980 nm) in Dentin Hypersensitivity Management: A Systematic Review

[摘要] Introduction: The present study aimed to describe parameters used with 808- to 980-nm wavelengthdiode lasers for managing dentin hypersensitivity and analyze their results.Methods: The inclusion criteria were based on randomized controlled clinical trials using diodelasers at an 808-980 nm wavelength range in patients with dentine hypersensitivity with a minimumof 1-month follow-up. An electronic search for articles on Medline, PubMed and Cochrane databaseswas performed. The risk of bias was assessed with the Cochrane collaboration tool.Results: Our electronic search resulted in 130 papers, of which 11 articles met the inclusion criteria.A majority of the studies assessed dentine hypersensitivity using the Visual Analogue Scale, whichranged between 2.3 and 8.8 before treatment and significantly reduced to a mean value of 0.45-3.7after diode laser application. The power settings ranged between 1.5 mW and 3 W with an emissionmode of continuous wave, except for 2 authors who used chopped mode. The energy density variedfrom 2.5 to 128 J/cm2, and the exposure time was between 10 and 120 seconds. The authors applieda minimum of 1 to 4 treatment sessions with a 2-day to 1-week interval between them. Most ofthe studies mentioned the tooth surface as the treatment site but without describing the specificirradiation points.Conclusion: Despite the heterogeneity of the analyzed variables, a statistically significantimprovement in all laser groups was described. However, they cannot be compared homogenously.
