Measurement of Light Energy Transmission Through Dental Hard Tissue at 450 nm, 650 nm, 810 nm, and 980 nm
The energy available to treat the dental pulp after transmittance through overlying structures is clinically important for determining photobiological effects. This ex vivo study aimed to quantify laser energy delivery though the dental crown to the pulp from an initial energy of 5 J using four common laser wavelengths (λ = 450, 650, 810, and 980 nm).
