Clinical evaluation of low‐level laser therapy and fluoride varnish for treating cervical dentinal hypersensitivity

摘要: The aim of this study was to evaluate in vivo the use low-level galium-aluminium-arsenide (GaAlAs) (BDP 600) laser and sodium fluoride varnish (Duraphat) treatment cervical dentine hypersensitivity. Twelve patients, with at least two sensitive teeth were selected. A total 60 included trial. Prior desensitizing treatment, hypersensitivity assessed by a thermal stimulus patients' response examination considered be control. GaAlAs (15 mW, 4 J/cm2) irradiated on contact mode applied region. efficiency treatments three periods: immediately after first application, 15 30 days application. degree sensitivity determined following predefined criteria. Data submitted analysis no statistically significant difference observed between laser. Considering separately, there for periods, therapy, (P < 0.05) found solely values obtained before It may concluded that both effective decreasing dentinal Moreover, showed improved results treating higher sensitivity.
