Comparing the effect of using vitamin C with injectable PRF as a locally delivered adjunct to scaling and root planing versus scaling and root planing with local delivery of injectable PRF and scaling and root planing alone on the clinical parameters in Stage II Grade A Periodontitis patients.

The conventional approach:

Group 1: Scaling and root planing alone using Gracey curettes and ultrasonic scalers.

Group 2: Scaling and root planing using Gracey curettes and ultrasonic scalers with local delivery of injectable PRF using an insulin syringe with the blunt needle inserted into the bottom of the periodontal pocket through a template to hold the locally delivered injectable PRF.

The intervention approach:

Scaling and root planing using Gracey curettes and ultrasonic scalers with local delivery of vitamin C (250 μM) and injectable PRF, using an insulin syringe with the blunt needle inserted into the bottom of the periodontal pocket through a template to hold the locally delivered vitamin C and injectable PRF for a longer time.
