EFFECT OF DIODE LASER IRRADIATION ON PERIODONTAL TISSUES DURING EXPERIMENTAL TOOTH MOVEMENT IN ALBINO RATS

Abstract

Introduction: Among the several tissue effects of laser irradiation arebiostimulation and photo disruption. What happens in the tissues is dependent onhow long the irradiation lasts and how much energy is given. Aim: This study setout to use histomorphometric analysis to determine how diode laser exposure affectedthe alveolar bone, periodontal ligament, and root surface in rats during experimentaltooth movement. Material and methods: Twenty albino rats were induced to haveorthodontic tooth movement group I (positive-control group) 10 rats got orthodontictooth movement alone and group II (study group) 10 rats got orthodontic tooth movementand subjected to Irradiation with Diode Laser (980 nm) applied perpendicular and incontact with the gums between two upper incisors with a power output of 300 mw. Theapplication was applied in a continuous mode. Histomorphometric analysis was doneat day 14. Results: Compared to orthodontic tooth movement alone, orthodontic toothmovement assisted by diode laser shows better results. All sites treated with orthodontictooth movement and diode laser showed a statistically significant improvement in allclinical markers. Conclusions: In orthodontic therapy, a low-level laser speeds up toothmovement by increasing metabolic activity in the alveolar bone around the teeth beingcorrected.
