Brief Summary

This double-blind randomized controlled clinical trial aimed to investigate the effect of staining beverage on color alteration of in-office tooth bleaching procedures.

Conditions

Tooth Discoloration

Keywords

tooth bleaching; staining beverage

Outcome Measures

Primary Outcomes (1)

• Change in tooth colour

  Colour parameters (CIE L\*, a\*, b\*) will be measured with a spectrophotometer (Vita Easyshade Advance 4.0). The color alteration after each session will be given by the differences between the values obtained at the sessions and the baseline (∆E).

  4 weeks

Secondary Outcomes (1)

• Change in tooth whiteness

  4 weeks

Study Arms (3)

control group

NO INTERVENTION

Participants will receive in-office tooth bleaching with 40% hydrogen peroxide (Opalescence Boost PF 40%) for the maxillary anterior teeth (2 sessions, with a 1-week interval).

coffee group

EXPERIMENTAL

Participants will receive in-office tooth bleaching with 40% hydrogen peroxide (Opalescence Boost PF 40%) for the maxillary anterior teeth (2 sessions, with a 1-week interval).During the tooth bleaching procedure and 3 weeks after the procedure,the participants will be instructed to make coffee rinses for 30 seconds, four times daily.

Behavioral: making staining beverage rinse during in-office tooth bleaching

tea group

EXPERIMENTAL

Participants will receive in-office tooth bleaching with 40% hydrogen peroxide (Opalescence Boost PF 40%) for the maxillary anterior teeth (2 sessions, with a 1-week interval).During the tooth bleaching procedure and 3 weeks after the procedure,the participants will be instructed to make tea rinses for 30 seconds, four times daily.

Behavioral: making staining beverage rinse during in-office tooth bleaching

Interventions
