Evaluation of Photodynamic Therapy in Pericoronitis

Sponsor: University of Nove de Julho

Summary

In order to reduce the chances of systemic dissemination of the infection and the use of antibiotics, it is mandatory to test effective treatments in the initial phase of pericoronitis aiming to avoid the evolution of the infectious disease. Photodynamic therapy (PDT) is an interesting alternative because it is an effective antimicrobial treatment that is easy to perform and does not cause bacterial resistance. The aim of this study is to evaluate the effectiveness of photodynamic therapy (PDT) with methylene blue in a surfactant vehicle in pericoronitis in the initial phase in healthy youngsters through microbiological, clinical and immunoregulatory response. The impact of pericoronitis on oral health-related quality of life (OHRQoL) of these patients will also be evaluated. 34 healthy young patients with pericoronitis will be evaluated. Microbiological analysis will be performed by RT-PCR for the bacterium Tannarella forsithia (Tf).Gingival crevicular fluid will be collected to evaluate TNF-α, IL1-β, IL-6 and IL-8 and IL-10 by the Luminex assay. The variables will be pain (visual analogue scale), edema, trismus (digital caliper) and oral health-related quality of life (OHRQoL) will also be evaluated through the OHIP-14 questionnaire. The variables will be assessed at T1 (baseline)and T2 (4th day after PDT).
