Photodynamic Therapy Using Zinc Oxide Photosensitizer As An Adjunct To Scaling And Root Planing In The Management Of Chronic Periodontitis - A Split Mouth Double Blind Randomized Controlled Clinical Trial.
Photodynamic Therapy Using Zinc Oxide Photosensitizer As An Adjunct To Scaling And Root Planing In The Management Of Chronic Periodontitis - A Split Mouth Double Blind Randomized Controlled Clinical Trial.
The present study aims to evaluate photodynamic therapy (PDT) using Zinc oxide as a photosensitizer as an adjunct to scaling and root planing (SRP) in the management of chronic periodontitis.
Following full mouth SRP, each quadrant will be randomly assigned by simple randomization using a computer generated randomization technique into one of the following four treatment modalities.
Group 1 (control) - Application of placebo gel followed by sham PDT (Directing the Light cure device without turning on the light beam).
Group 2 -Application of Zinc oxide gel followed by sham PDT. Group 3 - Application of placebo gel followed by PDT. Group 4 - Application of Zinc oxide gel followed by PDT. The procedure mentioned for each group will be performed on all periodontal pockets in the assigned quadrant at baseline, end of 1 week and 1 month from the first session.
Clinical parameters and microbial profile will be recorded at baseline (before commencement of Periodontal treatment), end of 1 month and end of 3 months following periodontal treatment.
Zinc oxide gel/placebo gel will be placed into the periodontal pockets using a blunt cannula ensuring that starting from the bottom, it completely fills the periodontal pockets. The gel will be retained in the pocket for 5 minutes. The perio tip will be attached to the hand piece of the light cure unit (Wavelength: 420-480nm. Light power: 1200mw/cm2 in continuous mode) and light will be activated for 60 seconds. Following this, the pockets will be irrigated with normal saline solution (0.9%Sodium chloride).
