Outcome Measures

Primary Outcomes (1)

  • Risk to Tooth sensitivity - during procedure

    The tooth sensitivity will be evaluated using a 5-point Verbal rating scale (VRS), where 0 = none, 1 = mild, 2 = moderate, 3 = considerable and 4 = severe. Score different from 0 will determine presence of sensitivity. The risk of tooth sensitivity will be determined by relative risk assessed by ratio between absolute risk of experimental condition by those observed in control. The 95% confidence interval will be calculated.

    During the bleaching procedure

Secondary Outcomes (3)

  • Level of tooth sensitivity - during procedure

    During the bleaching procedure

  • Risk of tooth sensitivity - after procedure

    24 hours after bleaching prcedure

  • Level of tooth sensitivity - after procedure

    24 hours after bleaching prcedure

Other Outcomes (1)

  • Efficacy of bleaching

    7 days after bleaching procedure

Study Arms (2)

Placebo

PLACEBO COMPARATOR
Drug: Naproxen

Naproxen

EXPERIMENTAL
Drug: Naproxen

Interventions
