Short‐term microbiological effects of photodynamic therapy in non‐surgical periodontal treatment of residual pockets: A split‐mouth RCT

Abstract

The combined therapeutic approach SRP + PDT may reduce A. actinomycetemcomitans levels for a short-term period, associated with additional improvement in clinical parameters in treating residual pockets. Lasers Surg. Med. 48:944-950, 2016. © 2015 Wiley Periodicals, Inc.

Clinical, microbiological and cytomorphometric evaluation of low‐level laser therapy as an adjunct to periodontal therapy in patients with chronic periodontitis

“…The present study found a significant decrease in prevalence of these bacterial species after the application of LLLT + SRP therapy, but not when only SRP was performed. Corrêa et al 's results are in agreement with our findings that significant reduction in mean prevalence of A. actinomycetemcomitans was found at LLLT‐treated sites, especially in the first reevaluation periods (3 and 7 days after therapy). Likewise, an additional reduction in some of these pathogens after adjunctive LLLT could be considered as a positive aspect and a possible benefit for the future maintenance of these results.…”

The effect of photodynamic therapy on pathogenic bacteria around peri‐implant sulcus and in the cavity between abutment and implant after healing phase: A prospective clinical study

“…Based on the evidence of the short‐term benefits of PDT to reduce bacterial counts, it might be useful as an initial treatment for suppressing the proliferation of bacteria, and adding the frequencies of application may lead to a more effective and satisfying result. This is also suggested by Corrêa et al that single‐episode PDT may not be sufficient, investigations on multiple courses effects are needed.…”

Efficacy of adjunctive photodynamic therapy in the treatment of generalized aggressive periodontitis: A randomized controlled clinical trial

“…Both treatment modalities being applied in this study led to significant decreases in the levels of all periodontopathogens. However, it was not possible to completely eliminate these microorganisms even from the sites assumed clinically healthy after treatment . Mechanical instrumentation decreases the subgingival microbial load and a microflora compatible with periodontal health is obtained .…”

“…PDT has a lethal effect against periodontopathogens as shown in a number of experimental and also clinical studies in humans . Qin et al demonstrated that total bacterial flora and clinical signs of periodontal inflammation could be reduced by toluidine blue O‐mediated photoinactivation in rats.…”

“…Consequently, the researchers suggested that a combination of both treatment methods would yield better results for the NPT of aggressive periodontitis. So, the use of PDT in the treatment of periodontal diseases is still an object of interest .…”
