[Abstract] AIM: To compare them icroleakage ofC lass V resin com pos ite restorations follow ing Er, Cr: Y -
GG laser and high- speed rotary preparation us ing a self- etch adhes ive system. MET ODS: Tw enty orthodontically
extracted hum an premolarsw ere random ly d ivided into two groups (n = 10) and C lass V cavitiesw ere prepared in the
teeth w ith Er, Cr: Y GG laser or bur. The cavitiesw ere then coated w ith FL- BOND adhesive system and TPH resin
com posite w as used for restoration. A fter finishing and polishing, the teeth were stored for seven days in d istilledw ater
at 37 e before they w ere subjected to therm ocycling for 500 tmi es ( 5 ? 2e - 55 ? 2e ). Th
