Diagnosis:
- Full history data will be collected, including personal, medical and previous dental data
- Clinical examination using mirror and probe to assess the inclusion criteria.
- Radiographic examination using preoperative digital periapical radiograph to assess the inclusion criteria.
- Preoperative photograph will be taken.
Operative procedure:
Experimental group:
- Injection of local anesthesia and rubber dam isolation.
- caries and roof of the pulp chamber will be removed by a fissure diamond bur (Diatech, Heerbrug, Switzerland) and high-speed handpiece with coolant.
- The pulps will be amputated to the orifice level using a long-shank diamond round bur.
- Haemostasis will be achieved by gentle placement of a saline-moistened cotton pellet over amputated pulps for 5-10 min.
- Calcium silicate-based BiodentineTM (Septodont Ltd., Saint Maur des Fausse´s, France) will be mixed according to the manufacturer's instructions, radicular pulp will be covered by the material using a wet cotton pellet.
- A self-cure glass ionomer (GC; GC Corporation, Tokyo, Japan) will be placed over the pulpotomy agent as a final restoration.
- Immediate post-operative radiograph and photograph will be taken.
Control group:
The same procedures will be carried out as the experimental group, but the pulp stumps will be covered with fast-setting mineral trioxide aggregate (MTA) ENDOCEM MTA (Maruchi, Wonju, Korea) and will be prepared according to the manufacturer's instructions. A 3-mm-thick layer of MTA will be placed over the amputated pulps and will be gently adapted to the dentinal walls using a wet cotton pellet. A self-cure glass ionomer (GC; GC Corporation, Tokyo, Japan) will be placed over the pulpotomy agent as a final restoration.
Postoperative care:
Instructions to avoid lip and cheek biting in addition to oral hygiene measures.
Follow up:
Assess the outcomes clinically and radiographically at (baseline, 6, 12 and 18 months).
