Efficacy of scaling and root planing with and without adjunct antimicrobial photodynamic therapy on the expression of cytokines in the gingival crevicular fluid of patients with periodontitis: A systematic review
Six clinical trials were included in the present systematic review. Two studies reported lower pro-inflammatory (IL-1β, TGF-β1 and MMP-8) cytokines among individuals that underwent SRP with adjunct aPDT compared with SRP alone. Three studies reported reduction in selective cytokines in the GCF following SRP with adjunct aPDT compared with SRP alone. In one study SRP with adjunct aPDT failed to reduce GCF IL-1β at follow-up.
