About this study
Official title: Efficacy of Some Different Photosensitizers in Photodynamic Inactivation of Periodontal Pathogens:A Randomized Clinical Trial
Dental biofilm is a primary etiological factor for periodontal diseases.(1) The bacterial biofilm would induce recruitment of leucocytes, neutrophils, and T lymphocytes and the secretion of antibodies, lipopolysaccharides, and chemical inflammatory mediators such as cytokines and chemokines.(2) Thus, periodontal diseases can cause tissue destruction and results in deterioration of clinical parameters measures such as periodontal pockets depth, clinical attachment loss, bleeding on probing, bone destruction, and resulting ultimately in tooth loss.(3)
Read the detailed description
Mechanical scaling and polishing are the conventional methods in treating periodontal diseases; however, due to difficulties in access to the irregular and furcation areas, it is impossible to be used as a sole means for calculus and bacterial deposit removal.(4) For this reason, adjunctive aids like systemic and local antibiotics are necessary to be administrated However, they have many adverse effects.(5) Another adjunctive aid like antibacterial photodynamic therapy (APDT), has been introduced to periodontology to achieve bacterial eradication, with minimum side effects.(6) APDT involves using visible light with an appropriate wavelength to kill microorganisms with a photosensitizing drug.(7) APDT could be an adjunctive aid to mechanical debridement in eliminating key periodontal pathogens. This therapy was specified as an oxygen-dependent photochemical reaction upon light-mediated activation of photosensitizing materials leading to cytotoxic reactive oxygen species (ROS) generation, predominantly singlet oxygen.(8) The activity of APDT is dependent on the combination of a non-toxic photosensitizer and a specific wavelength of visible light, which is activated and can promote a phototoxic response in the presence of ambient oxygen.(9) APDT is characterized by ROS generation by PSs in response to photo illumination, which later causes cell death.(6)

Questions about this trial
What is this clinical trial studying?
A study testing Methylene Blue and Toluidine Blue O in people with Periodontal Diseases and Periodontal Pocket, run by University of Sulaimani at 1 site in Iraq.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iraq. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 probing pocket depth (time frame: At the base line and three months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05162417, which also lists 9 linked publications.
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 29 Nov 2023.
