Detaljerad beskrivning
30 immature necrotic permanent teeth in patients will be allocated and divided into two groups.
Group 1 will be treated by regenerative procedure using blood clot as a scaffold and Group 2 will be treated with regenerative procedures using combined blood clot and Platelet rich fibrin as a scaffold.

Aktiv komparator: Induced blood clot scaffold
|
Bleeding will be induced in the canal by passing a size 30 sterile K-file 3 mm beyond the apex with the goal of having the entire canal filled with blood to the level of the cemento-enamel junction. Bleeding will be stopped just below the cemento enamel junction. Biodentine will be placed approximately 3-4 mm below the cementoenamel junction. |
|
Experimentell: Induced blood clot scaffold combined with Platelet rich fibrin
|
Platelet-rich fibrin will be prepared by drawing the patient blood into a 10mL test tube without the addition of an anticoagulant.
To prevent the blood from coagulating after coming in contact with the glass tube, it will be centrifuged immediately using a table top centrifuge** at 400 g force for 12 minutes.
Then platelet-rich fibrin membrane will be placed into the canal space to a level 3 mm below the cemento-enamel junction using hand plugger following the induction of apical bleeding by passing a number 30 sterile hand file 3 mm beyond the apex of the tooth.
Biodentine cap will be placed over the platelet-rich fibrin scaffold.
