These free radicals attack the organic molecules in the teeth and break the carbon double bonds into single bonds which ends up with teeth lighter in color. The mechanism of bleaching with hydrogen peroxide works by the breakdown of hydrogen peroxide (H 2O 2) molecules into hydroxyl free radicals. Bleaching is one of the least aggressive modalities that has gained popularity. More aggressive methods include external bleaching of vital teeth, micro abrasion of enamel with abrasives and acids, macro-abrasives, and crowns or veneers.

Tooth discoloration can be treated by different treatment approaches starting from the least invasive method such as whitening tooth paste, professional cleaning (scaling and polishing) to remove surface stains and internal bleaching of non-vital teeth.

Tooth discoloration has different etiologies this can be due to internal discoloration or external discoloration, or a combination of both. Patients are demanding a 'perfect smile'. Whiter teeth are believed to be associated with health or beauty. The different tested techniques presented a similar degree of hypersensitivity which faded in the 7 days follow-up.Д¬osmetic dentistry is becoming one of the leading concerns for most of our patients. Also, the different tested techniques showed equal color stability. Results: The current study found that there was no significant difference between mean values and standard deviation of the three bleaching techniques regarding color change (в€†E) and stability in follow-up periods hypersensitivity faded for all tested groups on a follow-up period of seven days.Д¬onclusion: The different tested bleaching techniques showed similar clinical efficiencies in a follow-up period of 6 months. Testing for hypersensitivity was completed immediately after treatment, 24 h after, 48 h after, and 1 week after treatment using a visual analog scale. Testing for color stability was completed at baseline, 1 day after, 1 week after, 1 month after, and 6 months after treatment using the VITA Easyshade В® spectrophotometer. Methods: A total of 21 patients were collected and randomly divided into 3 equal groups ( n = 7), the first group in-office treatment with 25% hydrogen peroxide, the second group at-home bleaching with 9.5% bleaching treatment), and the third group in-office and at-home as a combined treatment. Aim: In the management of patients with discolored teeth, would home bleaching alone or in combination with in-office bleaching give better tooth color stability than in-office bleaching? This study aimed to test the effect of different bleaching techniques on color change, stability, and hypersensitivity.
