Efficiency of Triple Antibiotic Paste, Ciprofloxacin/Propolis, Ciprofloxacin/Metronidazole, Propolis/Metronidazole Combinations on Revascularization Process of Immature Necrotic Maxillary Incisors of Patients 8-18 Years Old.

"Patients were treated as follows: Caries was excavated; access cavity was prepared. The rubber dam was then applied and working length was determined. Canal space was irrigated using 40 cc of NaOCl 2.6% solution and final flush of saline. Canal space was dried using paper points. One cc of the prepared paste was injected into the canals using a sterile plastic syringe with 20 gauge needle. The access cavity was then sealed using temporary restoration. After the 3 weeks, anesthesia without vasoconstrictor was administrated. The antibiotic paste was removed and the canal was irrigated using a sterile saline and dried using paper points. Sterile hand file size #25 was introduced into the root canal beyond the working length to induce bleeding. The bleeding was allowed to reach a 3-mm level below the cemento-enamel junction. MTA was used to seal the root canal at the cervical level. After one week, adhesive composite resin was used to seal the access cavity."
