Impact of Guided Biofilm Therapy on Epithelial and Mesenchymal Biomarkers in Periodontitis Patients

Impact of Guided Biofilm Therapy on Gingival Crevicular Fluid Epithelial and Mesenchymal Biomarkers in Periodontitis Patients: A Randomized Controlled Clinical Trial

Sponsor

University of Baghdad

Enrollment

18 participants

Start Date

Jan 4, 2026

Study Type

INTERVENTIONAL

Conditions

Periodontitis

Summary

The goal of this clinical trial is to investigate the clinical and biochemical effects of the guided biofilm therapy protocol as an alternative to the conventional non-surgical periodontal therapy in patients with periodontitis. The main question it aims to answer is: Does the guided biofilm therapy (GBT) protocol have an impact on gingival crevicular fluid (GCF) epithelial and mesenchymal biomarkers in patients with periodontitis? All patients will be instructed to brush their teeth twice daily and will be supplied with the same type of toothpaste and toothbrush, with suitable interdental aids. All patients will be instructed to attend again after 7 days. At baseline, full-mouth periodontal charting and radiographs will be obtained and after 1-hour, GCF samples will be collected from both test and control groups. Sites allocated to control group will undergo supragingival debridement by using ultrasonic device. After one week, the control group will receive RSD using area specific (Gracey) curettes (Medesy, Italy) according to the 24-hours protocol and will receive teeth polishing by using rubber polishing cups and tooth polishing paste, while the test group will receive a full GBT protocol which includes eight steps: (1) ASSESS, (2) DISCLOSE, (3) MOTIVATE, (4) AIRFLOW, (5) PERIOFLOW, (6) PIEZON PS\*, (7) CHECK, and (8) RECALL. After finishing the treatment session, the patients will be asked to attend for follow up, clinical evaluation of PI, BOP, PPD, and CAL, and GCF samples collection after 1 month and 3 months.

Interventions

PROCEDURERoot surface debridement

Control group sites that will receive conventional NSPT will undergo supragingival debridement by using ultrasonic device at baseline. After one week, sites will receive root surface debridement (RSD) using area specific (Gracey) curettes (Medesy, Italy) according to the 24-hours protocol.

DEVICEGuided Biofilm Therapy

Test group sites will receive guided biofilm therapy (GBT) protocol using the Airflow Prophylaxis Master device by EMS which includes EMS DISCLOSING AGENT making the biofilm visible, EMS AIRFLOW combined with PLUS erythritol powder for removing biofilm, discoloration, and early calculus, PERIOFLOW removing the biofilm in deep periodontal pockets gently and thoroughly, and finally PIEZON PS for removing the remaining calculus.
