PURPOSE To evaluate the in vitro effects of two bleaching products developed to be used with halogen or argon laser lights. METHODS 20 human embedded third molars were cut into four parts resulting in 75 useful specimens. The specimens were divided at random into five groups and submitted to the traditional power bleaching procedure for enamel. Group C(More)
This study compares the microleakage of a composite resin polymerized by using a commercial halogen lamp or an Argon laser operating in both single or multiline mode. For the microleakage experiment thirty restorations were prepared with the condensable composite resin in fifteen human superior premolars (two restorations per tooth). The restorations were(More)
