Abstract

Introduction: Among the several tissue effects of laser irradiation are
biostimulation and photo disruption. What happens in the tissues is dependent on
how long the irradiation lasts and how much energy is given. Aim: This study set
out to use histomorphometric analysis to determine how diode laser exposure affected
the alveolar bone, periodontal ligament, and root surface in rats during experimental
tooth movement. Material and methods: Twenty albino rats were induced to have
orthodontic tooth movement group I (positive-control group) 10 rats got orthodontic
tooth movement alone and group II (study group) 10 rats got orthodontic tooth movement
and subjected to Irradiation with Diode Laser (980 nm) applied perpendicular and in
contact with the gums between two upper incisors with a power output of 300 mw. The
application was applied in a continuous mode. Histomorphometric analysis was done
at day 14. Results: Compared to orthodontic tooth movement alone, orthodontic tooth
movement assisted by diode laser shows better results. All sites treated with orthodontic
tooth movement and diode laser showed a statistically significant improvement in all
clinical markers. Conclusions: In orthodontic therapy, a low-level laser speeds up tooth
movement by increasing metabolic activity in the alveolar bone around the teeth being
corrected.
