The Effect of I-PRF As An Adjunct to Non-Surgical Periodontal Therapy on Clinical Parameters in Smokers With Periodontitis

The non-surgical periodontal treatment (scaling and root planing) was applied under local anesthesia using ultrasonic device and Gracey curettes. After scaling and root planing, periodontal pockets were irrigated using saline solution. Non-surgical periodontal treatment was completed in one or two sessions within 24 hours.

For the subgingival saline application at the control sites, the insulin needle was filled with saline and the 29-gauge needle tip was gently placed into the periodontal pocket. The saline was injected into the periodontal pocket until it was seen to overflow from the gingival margin. Subgingival saline application was repeated on the 7th day.

For subgingival application of i-PRF at the test sites, the i-PRF taken into the insulin syringe, the 29-gauge needle tip was gently placed into the periodontal pocket and the i-PRF was injected into the periodontal pocket until it reached the gingival margin (until it overflowed from the sulcus). Subgingival i-PRF application was repeated on the 7th day.
