Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A clinical study will conduct on a sample of 40 adult patients in each patient with a non vital mature tooth. The sample will divide into 4 subgroups (10 in each group):
Biphasic Calcium Phosphate (BCP) scaffold and Bioceramic RRM, arm 1
Biphasic Calcium Phosphate (BCP) scaffold and MTA, arm 2
Blood clot scaffold and Bioceramic RRM, arm 3
Blood clot scaffold and MTA, arm 4
The canals will be prepared and the apical foramen will be enlarged to 0.60 mm, after that: Double Antimicrobial Paste (DAP) will be applied for a period of 3 weeks then it will be removed, then the induction of bleeding by bypassing the apex will be confirmed using 15 k-file and waiting for blood clot formation in the half of the sample while Biphasic Calcium Phosphate (BCP) scaffold will be applied in other half of the sample with two types of coronal sealing materials (Bioceramic root repair material BC RRM & Mineral Trioxide Aggregate MTA) will be used with both scaffolds.
Participants will be informed of the need to have a dental check-up periodically, and if any adverse event is observed, they will proceed to Plan B (conventional Root Canal Treatment RCT), with periodic reminder by short message service.
The application of all topical agents will be done by an experienced investigator and the intervention will be delivered at the clinics of the College of Dentistry.
Neutral investigators (Practitioners who don't know the applied materials) will monitor the cases clinically and radiologically during additional 5 successive visits prolong on periods 3-6-9-12-15 months; (each visit will last about 15 minutes, after two primary visits of about one hour each) and the results will be compared, where the absence of symptoms and clinical signs and the periapical healing will be considered as the main criterion of success.

Outcomes
Primary outcome [1] 324927 0
composite primary outcome regarding to
1: absence of symptoms (pain; according to visual analogue scale VAS)
2: absence of clinical signs (swelling, fistula, pockets according to community periodontal index of treatment needs CPITN and movement degree according to Miller scale)
3: periapical healing (according to periapical index PAI)
All that will be considered the main criterion of success, the observation will be done by blinded investigators using scoring criteria according to clinical and radiological scale suggested previously.
Timepoint [1] 324927 0
(T0) Baseline immediately after treatment
Revaluation in 5 intervals:
(T1) : 3 months after applying treatment.
(T2): 6 months after applying treatment.
(T3): 9 months after applying treatment.
(T4): 12 months after applying treatment.
(T5): 15 months after applying treatment.
Secondary outcome [1] 386237 0
Based on the method of assessment for each component
Patient discomfort, tooth movement, large swelling... etc are considered as an adverse events in accordance to success and failure criteria of American Association of Endodontics AAE.
Timepoint [1] 386237 0
It will be evaluated right after the patient complainment; adverse events will be monitored and after 6 months till 12 months then the plan b will start.

Summary
Brief summary
Modern bio-compatible materials which used after cleaning, disinfecting and bleeding of the mature roots can obtain predictable results, and this study is intended to compare the success of Regenerative endodontic procedures REPs on non vital mature teeth (which contains absence of signs and symptoms in addition to periapical healing, while the positive response to vitality is favorable but not imperative requirement), using Biphasic Calcium Phosphate (BCP) scaffold / blood clot scaffold and Bioceramic root repair material (BC-RRM) / Mineral Trioxide Aggregate (MTA) as coronal sealing material.
