A 0.014 stainless steel spring was inserted in the upper central incisors to produce 60gm force. Laser CAT 500 was applied for 3 min/day for 2 weeks. PPD measurements were obtained at base line and after 14 days with electronic periodontal probe.ResultsIL-6 levels increased gradually after application of orthodontic force, afterwards the 8th day, a significant difference in the Il-6 levels between G1 vs. G2 and G2 vs. G3 was observed. PPD measurements showed significant difference between the three groups at base line and after 14 days.Clinical SignificanceLLL application can enhance periodontal ligament regeneration and decrease the periodontal tissue destruction through suppression of IL-6 levels.RésuméObjectifÉvaluer les effets de la LLL sur les taux d’IL-6 dans le GCF et les mesures de la profondeur des poches au sondage (PPD) pendant le mouvement orthodontique dentai...
