This trial is active, not recruiting.
|Treatments||35% hydrogen peroxide, 20% hydrogen peroxide|
|Sponsor||University of Nove de Julho|
|Start date||February 2013|
|End date||September 2014|
|Trial size||53 participants|
|Trial identifier||NCT02414464, TBYP|
The aim of the present study was to evaluate colorimetric changes and tooth sensitivity in young patients submitted to tooth bleaching with 20% and 35% hydrogen peroxide.
|Endpoint classification||efficacy study|
|Intervention model||parallel assignment|
time frame: Change of teeth color after 48 hours, after 6 months, after 12 months, after 18 months
time frame: Sensivity alteration up to 48 hours after the procedure
Male or female participants from 11 years up to 24 years old.
- Individuals aged 11 to 24 years with a diagnosis of tooth discoloration and a signed statement of informed consent.
- Individuals with dentofacial anomalies, those without the permanent dentition complete to the second molars, those in orthodontic or orthopedic treatment of the jaws, those who took medications that could alter tooth color and those who had previously been submitted to tooth bleaching
|Official title||In-Office Tooth Bleaching for Young Patients Using a Hydrogen Peroxide-based Gel: a Randomized, Controlled, Clinical Trial|
|Description||A randomized, controlled, clinical trial was conducted with 53 patients aged 11 to 24 years who were allocated to groups based on the use of the following commercial products: Whiteness HP - FGM® (35% hydrogen peroxide); Whiteness HP Blue Calcium - FGM® (35% hydrogen peroxide); and Whiteness HP Blue Calcium - FGM® (20% hydrogen peroxide). After the bleaching procedure, the visual analog scale was used to measure tooth sensitivity and the classic Vita® scale was used to determine changes in tooth color. Statistical analysis involved the Friedman, Kruskal-Wallis and Student-Newman-Keuls tests, with p-value ≤ 0.05 or ≤ 0.0001 considered indicative of statistical significance.|
