Summary

The aim of this study is to compare clinical and radiographic evaluation treatment of necrotic immature permanent teeth using: 1. Concentrated Growth Factor 2. Blood Clot

Detailed description

Rationale for conducting the research: Concentrated growth factor (CGF) is relatively a new generation of platelet concentrate product, it contains more cytokines and growth factors compared with PRP and PRF also promotes the proliferation, migration, and differentiation of stem cells.

Conditions

• Revascularization

Interventions

Type	Name	Description
PROCEDURE	concentrated growth factors in open apex	Dry canals with paper points. A 10 ml of venous blood will be collected and transferred to sterile tubes without anticoagulant solutions by a trained nurse. The tubes will be centrifuged machine using a one-step centrifugation protocol at variable rpm, after centrifugation, four layers will be obtained: the first layer at the top is serum, second layer is the fibrin buffy coat, the third layer is the liquid phase containing growth factors, The concentrated growth factor was separated from the red blood cells and serum using sterile scissors. CGF will be packed into canal to the full working length using sterile pluggers. The coronal level of the CGF gel is near the cervical area above cementoenamel junction and white MTA placed as capping material after CGF, then GIC and composite restoration
PROCEDURE	Blood Clot (BC)	1. Create bleeding into the canal by over-instrumenting (induce by rotating a pre-curved K-file at 2 mm past the apical foramen with the goal of having the entire canal filled with blood to CEJ level) 2. Stop bleeding at a level that allows for 3-4 mm of restorative material. 3. Then white MTA as a coronal plug material be followed by GIC, then composite restoration.
