Randomized Clinical Trial Comparing the Effectiveness of Office Bleaching Agents in Patients of Different Age Group

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).
