Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change on visually determination of tooth colour | 2 weeks (before and after treatment) | Determination of tooth colour using a visual tooth shade guide |
| Change on spectrophotometer determination of tooth colour | 2 weeks (before and after treatment) | Determination of tooth colour using a spectrophotometer |
| Subjective evaluation of tooth colour change during follow-up | 1, 3 and 6 months | Determination of tooth colour relapse using visual tooth shade guide (VITA shade guide) |
| Change on quality of life during treatment and follow-up | 2 weeks (before and after treatment), 1 month, 3 months and 6 months | Impact on quality of life using an oral quality of life measuring questionnaire, the Oral Health Impact Profile 14 (OHIP-14). The OHIP-14 ranges from 0 to 56 (final sum of all the seven subscales), with higher scores indicating poorer quality of life. |
