Photodynamic in Periodontal Treatment

November 27, 2023 updated by: Sarhang Gul, University of Sulaimani

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)

Study Overview

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)

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control group
patient in this arm will receive scaling and root planning treatment only.
Experimental: Test group (toluidine Blue O)
patients in this arm will receive Toluidine Blue O as an adjunctive to scaling and root planing.
1mg/ml of Toluidine blue o as a solution will be used two times, first immediately after scaling and root planning, second after two weeks of the first treatment.
Experimental: Methylene blue
Patients will receive Methylene blue as adjunctive to scaling and root planning.
1mg/ml of Methylene as a solution will be used two times, first immediately after scaling and root planning, second after two weeks of the first treatment.
