NCT07794046

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 COMPARATOR

In 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.

Procedure: Nonsurgical Periodontal Therapy

Nonsurgical Periodontal Therapy Plus Alb-PRF

EXPERIMENTAL

In 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).

Procedure: Nonsurgical Periodontal TherapyOther: Albumin Platelet-Rich Fibrin

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.

Also known as: NSPT, Scaling and Root Planing, SRP
Nonsurgical Periodontal TherapyNonsurgical Periodontal Therapy Plus Alb-PRF

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.
