Group type: ACTIVE_COMPARATOR
Intervention: fluoride varnish
Description: fluoride varnish is usually applied to patients to prevent caries development but was claimed in some cases to also relief dentine hypersensitivity and was applied as a thin layer to the surface of the tooth using an applicator. The varnish set rapidly, and thereafter moisture contamination was not a concern. Patients were advised to not brush or floss their teeth for a couple of hours and to abstain from hot beverages. DH was assessed for tactile, cold, and air blast stimuli immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.

Intervention: Tetric N-Bond self-etch adhesive
Description: Tetric N-Bond self-etch adhesive is one step dental adhesive and is also claimed to relief dentine hypersensitivity due to blockage of dentinal tubules. It was applied according to the manufacturer's instructions, in a thick layer, for at least 30 seconds, using a light brushing motion. Then, it was dried with a steady stream of air for 3 seconds and light-cured for 10 seconds. DH was assessed for tactile, cold, and air blast stimuli immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.
