Technological innovations and advances in laser developments made possible its use in dentistry.
A laser produces a monochromatic light beam (i.e. defined by a single wavelength), narrow and specific, focusing a large amount of energy. Depending on the percentage of water and specific optical characteristics of the tissue to which it is directed, the light beam can be absorbed or on the contrary, pass through the target tissue.
The evolution of laser technology has been in the past rather slow due to the heterogeneity of tissues forming the mouth. Two examples are relevants : tooth enamel, composed by approximately 97% of hydroxyapatite crystals, is the most mineralized tissue of the human body, and on the contrary, the gum is abounding in water and hemoglobin.
Some of the latest dental lasers generation, highly efficient, make now possible treating both soft (gums, mucous membranes) and hard tissues of the mouth (enamel, bones...). They exhibit real benefits over traditional techniques and optimize most of dental care, from simple treatment of dental caries to the most complex surgery.Noticeably the use of laser allows to:
Especially, in endodontics, the laser guarantees high-quality care with maximum disinfection in just one session : root canals can be sealed immediately and risk of post-operative pain is reduced.
