Aggressive periodontitis is an inflammatory process of bacterial origin mediated by host immune response and is probably the most serious form of periodontal disease, with destruction of the structures of protection and support, with fast course, often leading to premature loss of the teeth and, in some cases, adjunct antimicrobial therapy is need in addition to mechanical therapy. The aim of this randomized controlled trial was to investigate the clinical effect of photodynamic therapy as an adjunct to nonsurgical periodontal treatment in patients with aggressive periodontitis. The following clinical parameters were evaluated: visible plaque index, bleeding on probing, probing pocket depth, relative attachment level, furcation involvement and mobility. We selected ten patients with aggressive periodontitis, which were examined in the baseline to three months. The study design consisted of a split mouth model, where a quadrant was treated with scaling and root planing and photodynamic therapy (diode laser) and the other only with scaling and root planing. Three months after the end of the treatment, the treatment groups showed similar results for all clinical parameters evaluated: both therapies have been successful and showed reduction of pocket depth, gain of relative attachment level, reduction of visible plaque index, reduction of bleeding on probing, decreased furcation involvement and decreased mobility, but without statistically significant differences between them. Within the limitations of the present study the results suggest that photodynamic therapy adjunct to non-surgical periodontal mechanic treatment was as effective as the non-surgical periodontal mechanic treatment alone.
