Description

Inclusion Criteria:

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention , MINST + IPRF
Participants will receive minimally invasive non-surgical periodontal therapy (MINST) with adjunctive local application of injectable platelet-rich fibrin (I-PRF) into the selected periodontal intrabony defect. I-PRF will be prepared from 10 mL of autologous venous blood and injected into the cleaned defect, followed by placement of a custom-made transparent vacuum-formed stent for 15 minutes to prolong local contact. Participants will receive standard oral hygiene instructions and periodontal follow-up.
Biological: Injectable PRF
I-PRF will be prepared from 10 mL of autologous venous blood and injected into the cleaned defect, followed by placement of a custom-made transparent vacuum-formed stent for 15 minutes to prolong local contact
Active Comparator: Control , MINST only
Participants will receive minimally invasive non-surgical periodontal therapy (MINST) alone for the selected periodontal intrabony defect, without adjunctive I-PRF or other biomaterials. Participants will receive standard oral hygiene instructions and periodontal follow-up.
Procedure: MINST
Participants will receive minimally invasive non-surgical periodontal therapy (MINST) alone using P3 Woodpecker piezoelectric scaler for the selected periodontal intrabony defect

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in pocket depth
Time Frame: 6 months
Baseline measurements will be taken at the first visit. Probing depth will be measured at six sites per tooth (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, distolingual) using a UNC-15 periodontal probe
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pocket closure
Time Frame: 6 months from baseline
Pocket depth of less than or equal 4 millimeters with no bleeding on probing at 6-month follow-up. PD will be measured from the gingival margin to the base of the pocket at six sites per tooth using a UNC-15 periodontal probe. PD reduction will be calculated by subtracting the 6-month PD from baseline PD
6 months from baseline
Clinical attachment gain
Time Frame: 6 months from baseline
CAL will be measured from the cementoenamel junction (CEJ) to the base of the pocket at the same six sites using a UNC-15 periodontal probe. CAL gain will be calculated by subtracting follow-up CAL (6 months) from baseline CAL
6 months from baseline
Radiographic defect reduction:
Time Frame: 6 months
Periapical radiographs of selected study sites will be taken at baseline and at 6 months using the parallel technique with Rinn holders. Each participating practice used the same setting and exposure time for radiographs taken at both visits to standardize positioning and minimize distortion of sequential radiographs
6 months
Patient reported outcomes
Time Frame: 6 months
To evaluate patient perceptions about the performed procedure and post-therapy period. The extent of discomfort and/or pain experienced will be evaluated using a horizontal visual analog scale (VAS).
6 months
