November 23, 2023 updated by: Yasmeen Khaled
Evaluation of L-PRF as an Antibiotic Slow-release Biological Device in the Treatment of Moderate Periodontitis (A Randomized Controlled Clinical Trial)
This study aimed to evaluate the efficacy of leukocyte platelet-rich fibrin (L-PRF) as a local sustained released device for antibiotics.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: L-PFR loaded with medical grade metronidazole
|
After phase I therapy, L-PRF loaded medical grade metronidazole was applied sub gingivally into the pockets using blunt gauge needle and Perio-pack was placed (two applications with one week apart were applied subgingivally.
|
Active Comparator: L-PFR
|
The L-PRF alone was applied subgingivally into the pockets and Perio-pack was placed (two applications with one week apart.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Plaque accumulation
Time Frame: up to 6 months
|
This was assessed using O'Leary plaque index which is based on the visible continuous plaque along the gingival margin after staining.
Four or six sites per tooth were examined, and the percentage of tooth surfaces exhibiting stained plaque was calculated.
The score ranges from 0% (no plaque) to 100% (abundant plaque)
|
up to 6 months
|
Gingival inflammation
Time Frame: up to 6 months
|
This was assessed using modified gingival index which uses a visual scale to assess gingival health.
It relies on a visual assessment of gingival changes to measure the severity of inflammation.
Five categories, using a 0-4 scale, score the marginal and papillary gingival tissue based on color, texture, edema, and spontaneous bleeding.
Using this index, 108 sites are scored per person (52 papillary and 56 marginal sites).
Score 0 indicates normal gingival, score 1: mild inflammation with slight changes in color and texture, but not in all portions of gingival marginal or papillary, score 2: Mild inflammation with slight changes in color and texture in all portions of gingival marginal or papillary, score 3: Moderate bright surface inflammation, erythema, edema, and/or hypertrophy of gingival marginal or papillary, and score 4: Severe inflammation with erythema, edema, and/or marginal gingival hypertrophy of the unit or spontaneous bleeding, papillary, congestion, or ulceration
|
up to 6 months
|
Bleeding on probing
Time Frame: up to 6 months
|
This was assessed using bleeding index which assesses bleeding on probing.
The number of sites where bleeding is recorded is divided by the total number of available sites in the mouth and multiplied by 100 to express the bleeding index as a percentage.
The score ranges from 0% (no bleeding) to 100% (bleeding in all sites)
|
up to 6 months
|
Probing depth
Time Frame: up to 6 months
|
The distance measured (mm) using a periodontal probe from the base of the pocket to the most apical point on the gingival margin.
It dictates the patient's ability to maintain optimal plaque control.
Probing depths in excess of 3mm are an indication for periodontal therapy.
|
up to 6 months
|
Clinical attachment loss
Time Frame: up to 6 months
|
It represents the extent of periodontal support that has been lost around a tooth and is measured with the periodontal probe as the distance (mm) from the cemento-enamel junction to the base of the pocket
|
up to 6 months
|
Quantitative assessment of Porhyromonas gingivalis
Time Frame: up to 6 months
|
Relative quantitation of Porhyromonas gingivalis counts was performed by Real Time PCR.
Subgingival plaque samples were calculated, DNA was isolated and quantified for standardizing the polymerase chain reaction.
|
up to 6 months
