Effectiveness of Office Bleaching Agents in Patients of Different Age Group
Condition: Satisfaction
Study type: Interventional

Summary: 
      To evaluate the effectiveness in terms of color variation, patient satisfaction, absolute
      risk and intensity of dentin sensitivity due to dental bleaching in the office with 35%
      hydrogen peroxide (Whiteness HP Automixx 35%, FGM) and Opalescence Boost 38% ( Ultradent,
      South Jordan, UT, USA) in the same arch in patients of different age groups: 18 to 25 years
      and 40 to 65 years. Data will be collected, tabulated and submitted to statistical analysis
    

Detailed description: 
      Throughout life, the aging of the human being as a whole is inevitable. The dental structure
      such as cementum and dentin undergo some changes over time, such as secondary deposition of
      dentin, which results in the reduction of root canal length. In addition, with aging the
      teeth undergo color changes, presenting a more yellowish or grayish coloration (Ravindra SV
      et al., 2015). The fact is that most of the studies that involve the technique of dental
      bleaching have as inclusion factor only young adult patients, excluding patients of more
      advanced age groups. Therefore, it is fundamental to evaluate the whitening technique in
      these older patients, since it is a treatment that does not cause harm to the individuals To
      assess the effect of dental bleaching in the office with Whiteness HP Automixx, FGM at 35%
      and Opalescence Boost at 38% in the same arch, in different age groups (18 to 25 years and 40
      to 65 years) in absolute risk and intensity Of the postoperative dental sensitivity through
      the visual analog (VAS 0-10) and analogue (NRS 0-4) scales.

        -  Evaluate the efficacy of Whitening HP Automixx, FGM 35% and Opalescence Boost 38% in the
           same arch in different age groups (18 to 25 years and 40 to 65 years) using Color Vita
           Classical and Vita Bleachedguide, and the Vita Easyshade spectrophotometer.

        -  Evaluate the satisfaction of patients after Whitening HP Automixx at 35, FGM and
           Opalescence Boost 38% in the same arch in different age groups (18 to 25 years and 40 to
           65 years).
