Sažetak
In 1964, when lasers were first considered for dental use, researchers have investigated various applications of laser in dentistry. Different studies have evaluated the ruby, CO2, Nd:YAG, Erbium (Er):YAG, excimer, and argon lasers for their effects on hard and soft tissues as well as dental materials. Er:YAG laser has a cutting mechanism in a way that water molecules in microscopic area on an irradiated surface absorb electromagnetic energy. The pressure produced, causes microexplosions and vaporization of the target materials.The potential of the Er:YAG laser to cut hard dental tissues such as enamel, cementum and bone, without significant thermal or structural damage has attracted attention. Er:YAG laser with a wavelength of 2.94 &micro ; ; m is used for tooth cavity preparations, as well as removing restorative materials, or endodontic surgery. A bloodless field is easier to achieve due to the ability of the laser to coagulate and seal small blood vessels. In contrast to this, low-power Nd:YAG laser was reported to have a significant reduction in permeability in resected roots. Development of the fibreoptic system of Nd:YAG laser, which enables the delivery of the light in a narrow, curved root canal, made this laser the most effective to sterilize exposed pulp tissues, or root canal walls after endodontic treatment. The Nd:YAG laser can be also used in treatment of oral soft tissue disease due to vaporization, coagulation or tissue ablation ability.
