Description

ABSTRACT
The aim of this study was to evaluate the effect of the Low-Level Laser Therapy (LLLT) on the rate of post-experimental tooth movement clinically, biologically and radiographically, and on the bone remodelling histologically. Sixty white rabbits were radiographic and histologically evaluated for the effect of local application of LLLT and VEGF (alone and in combination) on orthodontic movement.
Histological assessment for dental tissue response includes (periodontal ligament, cementum, and alveolar bone) to the application of LLLT and VEGF in orthodontic treatment. The data of the all experimental periods include the experimental tooth movement measurements (cumulative Measurements) and percentage; both of them were analyzed using both descriptive and inferential statistics shows Generally, combination group appear to be most effective and records a high value in all followings parameters in comparison to other groups.
