Abstract

Purpose: This study aimed to analyze the Low-Level Laser Therapy (LLLT) effect on periodontal parameters and the pain reduction during canine retraction in patients with compromised periodontium. Subjects and methods: Fourteen patients seeking orthodontic treatment, age ranging from 25-35 years old with compromised periodontium, were selected to participate in the present study. Patients were allocated randomly into two groups, Group I: control group. Group II: test group (LLL application). Bilateral extractions of the mandibular first premolars for all patients were done, then canine retraction was indicated. In laser group, application of LLLT was done on the mandibular anterior segment at 3,7,14,28,35,42 and 56 days intervals from initiation of canine retraction. Periodontal parameters; namely Gingival Index (GI), Plaque Index(PI), Probing Pocket Depth(PPD) and Clinical Attachment levels (CAL) of mandibular six anterior teeth were assessed before and after full canine retraction. The pain was evaluated for each patient by using visual analog scale (VAS), during 1st week of canine retraction. Results: GI and PPD in the laser group were significantly reduced while results revealed that no significant difference between the two groups regarding PI and CAL. There was no significant difference between Laser and control groups when pain was assessed on day 1,2,4 and 7 respectively during the first week of canine retraction. Conclusion: Low-level laser irradiation has a remarkable effect on inflammation control during orthodontic treatment of patients with compromised periodontium and has no effect on pain associated with canine retraction.
