And the third random number is attributed to the third method (laser). Each group is subjected to one of the following treatment methods: Method 1: Treatment with potassium nitrate Method 2: treatment with 5% sodium fluoride varnish Method 3: Low power diode laser treatment. N/A tooth sensivity. Intervention 1: Control group: Treatment with potassium nitrate. Intervention 2: Intervention group: treatment with 5% sodium fluoride varnish. Intervention 3: Intervention group: Low power diode laser treatment.
