Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
So, in this study the investigators will use Nano-BAG in combination with i-PRF as a material for pulpotomy in cases of mature permanent mandibular molars and compare its outcomes with using i-PRF only and in both cases pulpotomy material will be covered with a layer of premixed bioceramic putty for coronal sealing.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Research Question:
Will i-PRF mixed with Nano-BAG and covered with premixed bioceramic putty gives similar results in relieving pain , conservation of the radicular pulp vitality and dentin bridge formation compared with i-PRF alone covered with premixed bioceramic putty when using it as a material for pulpotomy in mature permanent mandibular molars?
Interventions:
A- Intervention for each group
a- General operative procedures
• Eligible patients will be randomized in equal proportions between the two groups.
Patients of the two groups will be subjected to:
* Diagnosis using diagnostic chart (appendix A) and selected according to inclusion and exclusion criteria
* Comprehensive clinical examination and understanding of patients' chief complaint and needs.
* Standard preoperative digital x-ray for all patients.
B- Intra operative procedures: (For both groups) Before anesthesia, surfaces of the teeth will be cleaned to be free of debris, calculus and plaque. Teeth will first be dried and isolated with cotton rolls and a tooth paste will be applied on the buccal face of the crown as an interface media. An electric pulp tester (EPT) probe will be placed on the sound coronal third of the labial surface and the responses will be recorded before starting the treatment. The contra lateral tooth will be tested first for comparison and then the subjected tooth will be checked.
The procedures will be performed under local anesthesia with Lidocaine 2% and adrenaline 1/100,000. Teeth will be isolated with rubber dam.
All carious tissue and old restoration (if present) will be removed with a diamond stone size 1 in a high speed hand piece with coolant , once the pulp is exposed the diamond stone will be changed and another sterile one will be used for complete deroofing of the pulp chamber. Then a sharp sterile excavator will be used for amputation of the coronal pulp tissue to the level of the root canal orifices.
Haemostasis will be achieved by pressing sterile cotton pellets soaked with sterile saline and damped into the cavity for 5-10 minutes over the pulp stumps (If haemostasis cannot be achieved after 10 mins, the tooth should undergo root canal treatment)
Care should be taken to minimize the time elapsed between coronal pulp amputation and placement of pulpotomy agent. The teeth will be then divided into two groups depending on the pulpotomy agents. I-PRF will be prepared according to Choukroun's technique by drawing a whole blood sample from the median cubital vein into a 10 ml plain test tubes (Non-citrated) to prevent blood coagulation then it will be centrifuged immediately using a table top centrifuge at 700 rpm for 3 mins The whole blood sample that will be obtained consists of three layers: the top most layer of acellular platelet poor plasma, the middle layer of platelet rich fibrin, and the bottom most layer of red blood corpuscles. The upper yellow fluid liquid (i-PRF) will be collected as close as possible to the layer of red blood cell.
Group A (the control group) :
After control of bleeding in teeth allocated to the control group i-PRF is to be injected first. The i-PRF will be injected into the root canal to a level 3 mm below the cementoenamel junction (CEJ).
Group B (In the intervention group):
After control of bleeding in teeth allocated to the intervention group, i-PRF is to be mixed with Nano-BAG powder to a putty consistency and injected into the root canal to a level 3 mm below the cementoenamel junction (CEJ), then a layer of premixed bioceramic putty is to be added for coronal sealing.
Coronal Sealing:
After a period of 10-15-minutes is allowed for coagulation, the coronal sealing material will be applied. The premixed bioceramic putty is dispensed on a sterile glass slab using a flat sided sterile plastic instrument. The material is applied over the coagulated scaffold in both groups using a dedicated carrier (MAP one) The material is adapted over the scaffold using light pressure adaptation with a sterile micro-brush of suitable size.
Final restoration:
A thin layer of resin-modified glass ionomer cement (RMGIC) to be applied directly over the coronal seal. Composite Resin material is to be used as a final restoration.

* The outcome assessors will be blinded.
* The operator will not be blinded for both materials during pulpotomy procedure as the two materials having different colors and different handling techniques.
