The aim of the present study is compare between the effect of surgical corticotomy and LLLT on the periodontal health.   methods: Orthodontic patients whom treatment necessitated maxillary 1st  premolar extraction followed by canine retraction, were recruited. Pre-intervention periodontal assessment was performed. At the day of premolar extraction, both interventions (corticotomy and LLLT) were randomly allocated to both sides of maxillary arch followed by canine retraction. Post-retraction periodontal assessment was done 6 months after start of canine retraction.   Results:  A statistical significant decrease by (0.29±0.57mm and 0.49± 0.75mm) was found in the gingival margin level of the maxillary lateral incisor on the corticotomy and Laser sides respectively. No statistical significant difference was found between both sides. Conclusions: Both interventions showed the same minor changes in the level of the gingival margin of maxillary lateral incisor.
