Effects of Adjunct Antimicrobial Photodynamic Therapy in Periodontal Treatment of Patients with Obesity

Not Applicable

Recruiting

• Conditions: Periodontitis; Obesity

• Registration Number: NCT06073704
• Lead Sponsor: University of Sao Paulo

Brief Summary

The goal of this clinical trial is to compare the effects of adjuvant antimicrobial photodynamic therapy (aPDT) as an adjuvant of scaling and root planing with scaling and root planing alone for periodontal treatment in patients with periodontal disease and obesity. The main question it aims to answer are: Does adjuvant aPDT improves periodontal health? Are there differences in the proteomic profile of gingival fluid after both treatments? Participants will receive scaling and root planing complemented or not by aPDT. Results will be collected after 1, 3, and 6 months. Researchers will compare adjuvant aPDT treatment to regular treatment to see if it promotes reduction in inflammation and improvement in periodontal health.

Primary Outcome Measures

Name	Time	Method
Clinical attachment level	Baseline, 1, 3 and 6 months	Changes in clinical attachment level measured from the cemento-enamel junction to the bottom of periodontal sulcus or periodontal pocket by a periodontal probe in millimeters.
Probing depth	Baseline, 1, 3 and 6 months	Changes in probing depth measured from the gingival margin to the bottom of periodontal sulcus or periodontal pocket by a periodontal probe in millimeters.

Secondary Outcome Measures

Name	Time	Method
Changes on bleeding on probing	Baseline, 1,3,and 6 months	Changes in percentage of sites with bleeding after probing. Six sites per tooth are examined and presence/absence of bleeding is recorded.
Differences in proteomics	baseline, 3 and 6 months	Changes in inflammatory proteins after treatment by proteomics assay. Presence or absence of proteins in gingival fluid are compared before and after treatment.
