NCT02666573

Brief Summary

27 subjects on SPT, each with at least two residual pockets ≥5mm, were recruited for this randomised, split-mouth controlled trial, providing a total of 72 sites. At baseline, probing pocket depth (PPD), recession, clinical attachment level (CAL), plaque and bleeding on probing (BOP) of all sites were examined. Gingival crevicular fluid (GCF) were collected to determine level of cytokines IL-1β, -6, -8, TNF-α and MMP-8 via ELISA. Control sites received subgingival instrumentation and rubber cup polishing with pumice. In addition test sites received a single application of PDT using Fotosan® and photosensitizer consisting of toludine blue O solution. The subjects were recalled three and six months later and re-examined. Site level analysis was performed.

Study Arms (2)

Photodynamic therapy protocol

EXPERIMENTAL

In addition to scaling and root debridement, test sites received PDT according to manufacturer's instructions.

Device: Fotosan 630, CMS Dental, Copenhagen, Denmark

SRP

OTHER

Scaling and root debridement of the residual pockets were performed using ultrasonic device and hand curettes until root surfaces felt hard and smooth. The sites were then polished using rubber cup and prophylaxis paste.

Other: Scaling and root planing

Interventions

The PDT system consists of a hand-held rechargeable light-emitting diode (LED) light source (Fotosan® 630 device, CMS Dental, Copenhagen, Denmark) and 0.1 mg/mL toluidine blue photosensitiser. The LED light source has a wavelength between 620 to 640 nm and peak of 630 nm and a power density between 2000 to 4000 mW/cm2.

Photodynamic therapy protocol

Scaling and root debridement of the residual pockets were performed using ultrasonic device and hand curettes until root surfaces felt hard and smooth. The sites were then polished using rubber cup and prophylaxis paste.
