Usage of Laser in Controlling the Evolution of Face Structures, An Approach of "Laser-Orthodontics", In Vitro

Background and Objectives: This is an endeavor to use Laser in controlling the evolution of the face structures, especially the condyle and the mandible bone. The aim of that study is to try to use laser in future for treating patients whose facial structures are predisposed to deviation in evolution and in growth. As a potential solution in prophylactic orthodontics, as "Chin-Cup, face-mask and head-gear" for instance, laser might be, one day, a potential substitution for controlling the evolution of those facial structures. Study Material and Methods: Three groups of Hamsters, each one comprises of three animals. Group A: Is the normal evolution group, or the surveillance group. Group B: The three hamsters of that group have been exposed to Chin-Cup, with moderate power on each side, about 450g. Per side. Group C: That group is the lased group, as the condyles of that group have been exposed to light energy of a diode laser. A red light at 650 nm with energy of 90m W/cm² had been used to perform light dosages 10 - 15 J/cm². Results: A long term study extended to seven months has shown an eminent slowness in the growth of lower jaws on both groups B and C, relatively to group A. The importance of such approaches is in the possibility of future usage of laser in controlling the evolution and growth of facial structures on humans.
