Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: To evaluate the effectiveness of tooth whitening with the use of bleaching toothpastes after daily use, according to the manufacturers' instructions for the two groups studied.;The efficacy and speed of the bleaching effect was assessed by color variation (Delta E) after one week of the bleaching session, end of treatment, 15 and 30 days after the end of the treatment, verified by a portable digital spectrophotometer (Easyshade-Vita, Brea, California, USA), according to the CIELab system, based on a variation of at least 5% in pre and post intervention measurements. The evaluated toothpastes were not able to produce a whitening effect similar to supervised bleaching. The durability (maintenance) of the whitening effect obtained with dentifrices is small, with total reversion of the coloration in 30 days. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome 1: Evaluate the presence of gingival changes. The incidence of dental sensitivity during and after treatment. The degree of patient satisfaction regarding the result obtained.;Secondary outcome found 1: In each evaluation, the gingival condition was evaluated through clinical examination, where its characteristics were observed as texture and coloration. It was not possible to observe presence of significant gingival alterations for any of the groups. Patients were questioned about the occurrence of dental sensitivity during and immediately after the use of whitening products. The measurement of this sensitivity was done through a visual analog scale, applied through a form filled out by the patient himself. There was no difference between the groups for the reports of sensitivity. At the end of the treatment the patients were evaluated as to the degree of satisfaction with the technique and with the results obtained, by filling out a specific form. The degree of patient satisfaction regarding the result obtained revealed a statistically significant difference between the groups, due to the low whitening effect of the bleaching dentifrices. The obtained data were tabulated and underwent statistical analysis of the descriptive and inferential type. | — |
