Abstract

Laser effect on enamel is manifested as consequence of temperature changes. Enamel melts, vaporises and a crater, and fissures are formed. Retention surface for anchoring of composite resin was obtained in intact approximal surfaces of premolars with C 02 laser (0.5, 1 and 3 W, sport size 1 and 1.5 mm, 0,2 and 0,5 s). The study results reveal composite and lased enamel interfaces are stronger then composite and inlased enamel (p<0 .0 1 ) but weaker than composite and acid pretreated enamel interface (p<0 .0 1 ).
