Conclusion
PERIODONTITIS, PCT
All four treatment modalities employed in the study, aided by the meticulous oral hygiene maintenance of the participants, resulted in an overall improvement of all clinical parameters and microbiological profile assessed after 3 months. At the end of month 1, it was found that the repeated application of PCT as an adjunct to SRP, using bio-hydrothermally synthesized Nano ZnO gel in combination with visible light in the range of 420-480 nm, produced a significantly better short-term improvement in treatment outcomes than SRP alone—but this difference between the two treatments was not sustained until the end of month 3. All groups except for the one that received the adjunctive PCT application experienced an increase in Longitudinal studies with a larger sample size and a longer follow-up period can further validate the beneficial effects of the adjunctive application of PCT using bio-hydrothermally synthesized Nano ZnO gel and visible light in the range of 420-480 nm in the treatment of periodontitis.
