Injectable Platelet-Rich Fibrin and Microneedling For Papillae Reconstruction In Esthetic Zone (iPRFandMN)

November 5, 2023 updated by: Yasmeen Saleh Tolba, Cairo University

Injectable Platelet-Rich Fibrin and Microneedling For Papillae Reconstruction In Esthetic Zone (A Case Series )

The currently available non-surgical techniques for papillary reconstruction did not provide long term maintenance of papillary regeneration, Surgical techniques are invasive and the results are unpredictable . The study is based upon the positive effects of iPRF upon enhancing wound healing in terms of new collagen formation, angiogenesis and increasing keratinized tissue phenotype . iPRF exhibited comparable effects to subepithelial connective tissue graft in papillary reconstruction . The effect of microneedling on the tissue responds as if experiencing tissue trauma and the body's own collagen production is induced to preserve tissue integrity . Growth factors are released immediately after injury, inducing the proliferation of new cells, and fibroblasts are transformed into collagen and elastin fibres from day 5 up to week 8 .

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The patients diagnosed with black triangles according to Norland classification system for loss of papillary height will be selected. Each patient will receive a proper knowledge of the study protocols along with full-mouth scaling and root planing (SRP) using ultrasonic and hand instruments and will be given personalized oral hygiene instructions. After oral prophylaxis and baseline measurements of insufficient interdental papilla the treatment will be MN and iPRF. First, MN will be done in the required area with insulin syringe gauge 30,The interdental papilla will vertically and horizontally measured in mm. By establishing a ratio and proportion, the number of microchannels in the region to be treated will calculated to be 250 microchannels per square cm. Then, a venous blood sample will be taken for each patient using a 10-ml injector into i-PRF tube containing no anticoagulant and centrifuged at room temperature for 3 min at 700 rpm (60 g force). The 30-gauge dental injector needles will be used for injection of i-PRF. The needle will be inserted at 45° angle, 2-3-mm apical to the involved papilla and all surrounding areas will receive iPRF. Each involved papilla will be injected with an amount till blanching is visible . This method will be repeated for 4 times at 10 days intervals consecutively. The final clinical photographs and measurements will recorded 3 and 6 months of last dose administered . After the intervention, patients will receive oral hygiene instructions that include the roll technique when brushing without the use of floss and toothpick during the study period to minimize trauma to the treated site .

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Nonsmoking patients aged above 18 years.
  • At least one site with interdental papilla recession in the anterior region of the maxillary or mandibular jaws.
  • The distance from the contact point to alveolar bone is crest < 7 mm.
  • Class I or Class II papillary recession, according to Nordland and Tarnow's classification systems (Nordland et al., 1998).
  • No active periodontal diseases and good oral hygiene.

Exclusion Criteria:

  • Patients were excluded from the study if they have:
  • Spacing or crowding between the teeth to be treated
  • Abnormal tooth shape
  • Systemic diseases such as diabetes mellitus, hypertension or conditions that alter the outcome of periodontal therapy.
  • In addition, patients will be excluded if they are Pregnant and lactating women.
