Photodynamic therapy, Interleukin 1-beta, Tumour necrosis factor - alpha, Interleukin-6, Interleukin-8, Matrix metalloproteinase-8

Brief summary

Systemically healthy periodontitis patients were recruited in this single-blind, split-mouth, randomized controlled clinical trial. After SRP, PDT was applied at probing depth (PD) ≥ 4 mm at test quadrant. At baseline, 3rd month and 6th month, clinical parameters and cytokine pattern in gingival crevicular fluids (GCFs) were analysed.

Detailed description

Periodontal parameters and cytokine IL-1β, IL-6, IL-8, TNF-α, MMP-8 levels were analysed.

Interventions

DEVICESRP and Fotosan 630

After isolating the test quadrants with cotton roll, toluidine blue was applied into the deep pockets (PD ≥ 4mm) at the test quadrants for 10 seconds, followed by inserting a perio tip (15 or 21 mm depending on the depth of the pocket) that connected to a LED emitting device, and light was emitted for 20 seconds. Toluidine blue in the deep pocket was removed by injecting normal saline into the pocket.

TRIPLE (Subject, Caregiver, Investigator)

Masking description

Allocation of test and control quadrants were done randomly by asking each study participant to choose either numbers 1 or 2. Number 1 defined quadrants 1 and 3 as the test quadrants while number 2 referred to quadrants 2 and 4 as the test quadrants. The remaining quadrants served as the control quadrants.
