About this study
Official title: 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.
Read the detailed description
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).

Photodynamic therapyProcedure or surgery
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.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Microbial profile (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Feb 2019; AzTrials last refreshed its copy on 7 Nov 2026.
