Management of Dentin Hypersensitivity in Patients With Periodontitis

Participants in this group received both treatments: Gluma was applied using the same method as in Gluma, followed by Er,Cr:YSGG laser therapy using the same parameters and technique as in laser.

Participants received Er,Cr:YSGG laser treatment (Water-Lase iPlusTM; Biolase® Technology Inc., Irvine, CA, USA). Laser parameters were set as follows: 2780 nm wavelength, 0.25 W power, 20 Hz frequency, 140 μs pulse duration, and 30 seconds exposure time. The MZ6 tip (660 μm diameter, 6 mm length, 1 mm spot size) was used in non-contact mode from a 1 mm distance, perpendicular to the dentin surface, with 0% water and 10% air spray. All laser applications followed international safety standards and protocols.
