IRCT20130813014350N3 IRCT 2020-05-24 Dental Research Centre, Guilan University of Medical Sciences Effect of injectable platelet-rich fibrin in post-operative healing after tooth crown lengthening surgery Evaluation of injectable platelet-rich fibrin in post-operative healing after tooth crown lengthening surgery 2020-05-06 anticipated 16 Complete https://irct.ir/trial/43273 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: The permutation block method is used to randomize treatments. Considering blocks of 4, respectively, people will be included in the study if A receives treatment on the right and B receives treatment on the left and the other is considered as control: Seed: 272654992542016 Block sizes: 4 Actual list length: 16 block identifier, block size, sequence within block, treatment, code • 1, 4, 1, Group A, ZN6 • 1, 4, 2, Group A, AA8 • 1, 4, 3, Group B, ZR9 • 1, 4, 4, Group B, TS5 • 2, 4, 1, Group A, PG3 • 2, 4, 2, Group A, ZS4 • 2, 4, 3, Group B, ZQ3 • 2, 4, 4, Group B, DG0 • 3, 4, 1, Group A, JR0 • 3, 4, 2, Group B, GS3 • 3, 4, 3, Group A, KG1 • 3, 4, 4, Group B, HQ6 • 4, 4, 1, Group A, RR5 • 4, 4, 2, Group B, FA1 • 4, 4, 3, Group B, KG7 • 4, 4, 4, Group A, ER9, Blinding description: The research will be conducted in single blinded manner. To blind the patient, the researcher performs all operations on the intervention side during surgery on the control side only at the time of i-PRF injection but does not inject the insulin needle. 3 Evaluation of injectable platelet-rich fibrin in post-operative healing after tooth crown lengthening surgery. Intervention 1: Intervention group: Gingival surgery to increase the length of the crown and in order to, injecting 1 cc of i-PRF ( from 10 cc of the patient's blood in the centrifuge device (DR. CHOUKROUN DUO QUATTRO PRF CENTRIFUGE) speed 700 rpm for 3 minutes And the clear part of the fluid above the tube (i-PRF) with the insulin syringe stretched) in the patient's gums.Clinical postoperative examinations and photographic imaging are performed using the Visual Analogue Index as the primary outcome and the Early Healing Index scale as the secondary outcome on days 2, 4, 7, 10, and 14. Intervention 2: Control group: Gingival surgery in order to increase the length of the tooth crown without injecting any substance was performed .Clinical postoperative examinations and photographic imaging are performed using the Visual Analogue Index as the primary outcome and the Early Healing Index scale as the secondary outcome on days 2, 4, 7, 10, and 14. Yes - There is a plan to make this available What will be shared: Evaluation of injectable platelet-rich fibrin in post-operative healing after tooth crown lengthening surgery among patients referred to periodontal department of Guilan dentistry Faculty When: Access time 6 months after publishing the results To whom: Researchers working in academic institutions Conditions: Researchers working in academic institutions Where to obtain: Bardia@gums.ac.ir How to obtain: 2 months Comments:
