NCT03576105

Brief 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).

Outcome Measures

Primary Outcomes (1)

  • Microbiological analysis will be performed by RT-PCR for the bacterium Tannarella forsithia (Tf)

    Sample collection for microbiological analysis Biofilm collection will be done at two points of the vestibular gingival sulcus of the lower third molar using minifive curettes. The collected material will be maintained in TE (Tris-EDTA), conditioned in microtubes and later transported for laboratory analysis in the Microbiology Laboratory of ICB-USP Prof. Marcia Mayer

    change from baseline, immediately after PDT and on fourth day after PDT

Secondary Outcomes (6)

  • Profile of cytokines Gingival crevicular fluid will be collected

    change from baseline and on fourth day after PDT

  • pain assessed by Vas

    change from baseline, immediately after PDT and on fourth day after PDT

  • edema assessed by measuring facial distance

    change from baseline, immediately after PDT and on fourth day after PDT

  • trismus assessed by measuring bucal opening

    change from baseline, immediately after PDT and on fourth day after PDT

  • OHRQoL assessed by ohip-14

    change from baseline, immediately after PDT and on fourth day after PDT

  • +1 more secondary outcomes
