ABSTRACT
Bleaching of discolored teeth is one of the most important topics in aesthetic dentistry. A great challenge in this area is obtaining good results in tetracycline-stained teeth. The wavelength and features of KTP laser, which is a type of Nd:YAG laser, seem to be appropriate for bleaching of these teeth. This case report underlines the importance of knowledge about the photochemical bleaching by using the KTP laser and its side effects on soft tissues.

After 30 seconds’ irradiation for each tooth: Half of the hydrogen peroxide gel was vaporized off. Gum protector (light-cured soft composite resin) is recognized.

f3-0030229: After 30 seconds’ irradiation for each tooth: Half of the hydrogen peroxide gel was vaporized off. Gum protector (light-cured soft composite resin) is recognized.

Mentions: 35% hydrogen peroxide gel (Smartbleach, SBI nv., Herzele, Belgium), with pH around 10, was prepared after mixing with buffering powder just before the treatment. Hydrogen peroxide can easily damage soft tissues, so light-curing soft composite resin (Smartblock, SBI nv., Herzele, Belgium) was placed at the marginal borders as a gum protector (Figure 3). Bleaching gel was placed on the tooth surface, and KTP light (SmartLite, Deka, Frenze, Italy) by 532 nm wavelength and 1 watt power was irradiated for 30 seconds for each tooth. The distance between the instrument tip and tooth surface was kept at 10 mm. Circular motion was employed to prevent overheating.
