LD specimens lased (Er;Cr:YSGG) with 3.75 W power and 15 Hz frequency for 4 min showed bond strength comparable with HF acid samples, and color changes within acceptable range (ΔE 1.17). Laser treatment (Er;Cr:YSGG) at 3.75 W power and 15 Hz frequency for 4 min of LD ceramics appears to be clinically efficient, showing acceptable bond strength and color stability.
