Summary

The goal of this split mouth clinical trial is to compare clinical efficacy of diode laser and gas ozone in the treatment of dentine hypersensitivity (DHS) of non-carious-cervical lesion. The main questions it aims to answer are: * gas ozone affects dentine hypersensitivity? * diode laser affects dentine hypersensitivity? Participants, affected of DHS , were treated with gas ozone and diode laser.The pain severity was quantified according to the Visual Analogue Scale (VAS) before and after the treatmens.

Conditions

• Dentin Sensitivity

Interventions

Type	Name	Description
COMBINATION_PRODUCT	Gas ozone	The application of ozone was performed with the HealOzone System X4 (HealOzon, Kavo, Germany). The dentist adapted the silicon cup stricken on the cervical surface of the teeth. The pumping system created the vacuum and the machine applied high dosage of ozone, equal to 32 g/m3, for 30 second.
COMBINATION_PRODUCT	Diode laser and desensitized gel	The dentist applied desensitized gel (JW-Desensitizing Gel, Heydent Gmbh, Germany) directly on the cervical zone of the teeth. Subsequently the irradiation was performed with Wiser III (Wiser, Doctor Smile, Italy) in the desensitizing assisted mode (preprogramed protocol). The protocol provides consecutively steps (not in contact) with 20 second of interval, 808 wavelength, and power incrementation, from 0,2 till 0,6 W. radiating the entire desensitize surface second using the "black tip" (400 micron). The procedure continued maintaining the tip of the laser on contact with the dentine surface making movement of lawn mowing (brushing technique) for 30 second. Then the surface was rinsed, and the irradiation applied again without the gel.
