Abstract
Objective
To compare the ablation ability of nucleus pulposus after 1,064 nm Nd:YAG laser and 980 nm diode laser radiation.
Methods
Goat spine specimen (GSS) was radiated using Nd:YAG laser and 980 nm diode laser and then divided into five groups based on the final energy—200, 400, 600, 800 and 1,000 J groups. The ablation quality of nucleus pulposus after radiation was recorded.
Results
The ablation quality of GSS was greater at higher radiation energies in both lasers. When compared at the same energy level, the ablation quality of GSS was greater in 980 nm diode laser than in 1,064 nm Nd:YAG laser. Statistical significance was observed in 200 and 400 J groups (P < 0.05) and in 600, 800 and 1,000 J groups (P < 0.01).
Conclusion
Radiation with 980 nm diode laser showed better ablation ability than 1,064 nm Nd:YAG laser.
