Brief Summary
Periodontitis is an inflammatory disease that damages the tissues supporting the teeth. Nonsurgical periodontal therapy is the standard initial treatment, but deep periodontal pockets may remain after treatment. Albumin platelet-rich fibrin (Alb-PRF) is an autologous material prepared from the participant's own blood and applied locally to support periodontal healing. The main purpose of this study is to determine whether applying Alb-PRF into periodontal pockets in addition to nonsurgical periodontal therapy provides greater clinical improvement than nonsurgical periodontal therapy alone. The study will also evaluate whether the additional application of Alb-PRF affects the levels of selected bacteria associated with periodontitis. This randomized split-mouth study will include 24 adults with periodontitis. In each participant, matched periodontal sites will be randomly assigned to receive either nonsurgical periodontal therapy alone or nonsurgical periodontal therapy followed by an intrapocket application of Alb-PRF. Clinical periodontal measurements will be recorded at baseline and at 1, 3, and 6 months. Subgingival plaque samples will be collected from the same sites at baseline and 30 days after treatment. The primary outcome is the reduction in periodontal probing depth from baseline to 3 months.

Outcome Measures
Primary Outcomes (1)
Change in Periodontal Probing Depth
Periodontal probing depth (PPD) will be measured in millimeters using a periodontal probe at the randomized control and Alb-PRF-treated sites. PPD reduction will be calculated by subtracting the 3-month PPD value from the baseline PPD value. A higher positive value indicates a greater reduction in probing depth.
Baseline to 3 months
Secondary Outcomes (6)
Change in Clinical Attachment Level
Baseline to 3 and 6 months
Change in Bleeding on Probing
Baseline to 1, 3, and 6 months
Change in Plaque Index
Baseline to 1, 3, and 6 months
Change in Gingival Index
Baseline to 1, 3, and 6 months
Change in the Proportion of Sites With Periodontal Probing Depth of 5 mm or Greater
Baseline to 3 and 6 months
- +1 more secondary outcomes
Other Outcomes (3)
Change in Porphyromonas gingivalis Bacterial Load
Baseline to 30 days
Change in Aggregatibacter actinomycetemcomitans Bacterial Load
Baseline to 30 days
Change in Prevotella intermedia Bacterial Load
Baseline to 30 days
Study Arms (2)
Nonsurgical Periodontal Therapy
ACTIVE COMPARATORIn each participant, the periodontal site randomly assigned to the control arm will receive standard nonsurgical periodontal therapy, including oral hygiene instruction and supra- and subgingival mechanical debridement. No additional intrapocket material will be applied to the control site.
Nonsurgical Periodontal Therapy Plus Alb-PRF
EXPERIMENTALIn each participant, the matched periodontal site randomly assigned to the experimental arm will receive the same nonsurgical periodontal therapy as the control site, followed by the local intrapocket application of autologous albumin platelet-rich fibrin (Alb-PRF).
Interventions
Nonsurgical periodontal therapy will include individualized oral hygiene instruction and supra- and subgingival mechanical debridement using periodontal hand instruments and/or ultrasonic devices. This intervention will be administered to the periodontal sites assigned to both study arms.
Alb-PRF will be prepared under sterile conditions from autologous venous blood collected from each participant during the treatment visit. The albumin-containing plasma fraction will be heated at 75°C for 10 minutes and then combined with the appropriate liquid platelet-rich fibrin fraction to produce the Alb-PRF matrix. The freshly prepared Alb-PRF will be applied locally into the periodontal pocket immediately after nonsurgical periodontal therapy.
Eligibility Criteria
You may qualify if:
- Adults aged 18 to 65 years.
- Diagnosis of periodontitis according to the 2017 classification of periodontal and peri-implant diseases and conditions.
- Presence of at least two clinically comparable periodontal sites within the same mouth that are suitable for a split-mouth design.
- Periodontal probing depth of 5 mm or greater at the sites selected for randomization.
- No systemic condition that would contraindicate nonsurgical periodontal therapy or adversely affect periodontal healing.
- No current use of medications known to affect periodontal tissue healing.
- No periodontal surgical treatment within the previous 6 months.
- Ability to understand the study procedures, provide written informed consent, and attend the scheduled follow-up visits.
You may not qualify if:
- Current smoking or smoking cessation within the previous 6 months.
- Diabetes mellitus, uncontrolled hypertension, serious cardiovascular disease, autoimmune disease, liver failure, kidney failure, or another systemic condition that may adversely affect periodontal healing or treatment.
- Use of antibiotics, corticosteroids, bisphosphonates, antiresorptive agents, immunosuppressive agents, or other medications known to affect periodontal healing within the previous 6 months.
- Pregnancy or lactation.
- Acute periodontal abscess or acute endodontic infection at a selected study site.
- Hematologic disease, bleeding disorder, anticoagulant therapy, or another condition that may interfere with venous blood collection.
- Known hypersensitivity to any material used in the study.
- Inadequate oral hygiene or inability to meet the oral hygiene requirements of the study protocol.
- Current orthodontic treatment.
- Inability or unwillingness to attend the scheduled follow-up visits.
