Abstract

Laser radiation having a selected wavelength and in the form of pulses having a selected pulse duration, repetition rate and energy content per pulse, is employed for performing a variety of dental and medical procedures, including cutting of enamel, dentin, cementum, dental root material, bone and metal. Cavities and openings in teeth and bones can be filled with a mixture containing hydroxyapatite and phosphoric acid, mixed together to form a paste, and the resulting mixture, after being introduced into the opening or cavity, can be cured and hardened by application of pulses of defocused laser radiation.
