Evaluation of the Effectiveness of 5% Sodium Fluoride (NAF) with Diode Laser 976nm for Treatment of Dentine Hypersensitivity
Keywords:5% NaF,diode laser 976nm, DH; patients
Background: dentin hypersensitivity (DH) is a painful condition that is highly prevalent in the world’s adult
Aim: The aim of this study was to compare the efficacy of fluoride varnish (5% sodium fluoride)irradiation
with diode laser in the treatment of dentin hypersensitivity in non caries cervical lesion(NCCL) patients.
Materials and Methods: Twenty patients with 90 teeth were divided into two groups: Group 1, teeth treated
with diode laser with5 J/cm2 energy density;Group 2, teeth treated with NaF irradiated with diode laser with
same previous diameter.
Results: The two treatments were applied to the buccalcervical region with three follow up intervals 30
minutes,2 weeks and one month. The response of the patient to thermal-evaporative stimuli was rated on a
Schiff cold air sensitivity scale. The results showed a reduction of hypersensitivity in response to thermalevaporative
stimulation at the end of treatment in both groups.
Conclusion: dentine hypersensitivity treatment withNaF+diode laser was found to be more effective than
low-level laser radiationimmediately
