简要总结
enrollment of the patient after diagnosis, radiographic evaluation, and signing the informed consent.
allocation of the patient to either intervention or control group. After anaesthesia and access cavity, the first root canal sample will be taken. Endodontic treatment will be completed in one visit. The second root canal sample will be taken. Patients will be asked to evaluate their postoperative pain level using VAS scale at 6, 12, 24 hours, and daily up to 5 days. Patients will record the number of analgesics if any taken.
详细描述
After diagnosing the case as asymptomatic pulp necrosis and confirming that the patient conforms to all eligibility criteria, (R.S) will enroll the patient in the study.
the operator will complete treatment of all cases in single visit as following:
- Anesthetizing the tooth using inferior alveolar nerve block technique
- Removal of Caries and/or coronal restorations completely with sterile bur and rubber dam will be applied.
- Preparation of access cavity using another sterile round carbide bur size 3 and Endo-z bur .
- (R.S) will take the preinstrumentation root canal sample (S1)
- Confirming the patency of the root canals using stainless steel hand K-files size #10 and #15 . Working length will be determined .
- In the intervention group, (R.S) will perform mechanical preparation in a 3D manner using Xp-endo Shaper single file in an endodontic motor at a speed of 800 rpm and a torque of 1 Ncm.
- In the control group, mechanical preparation will be done using rotary iRace files (#25/0.04, #30/0.04, and #40/0.04) at a speed of 600 rpm and a torque of 1.5 Ncm. The canal will be irrigated and recapitulated after the use of each instrument.
- EDTA gel will be used as a lubricant. The canals will be thoroughly irrigated using 3ml of 2.5% sodium hypochlorite.
- The canal will then be dried by using sterile paper points and then flushed with 5 ml of 5% sodium thiosulfate to inactivate the NaOCl. The postinstrumentation sample (S2) will be taken from the canals.
- Master cones will be fitted to the working length and a radiograph will be taken to ensure proper length.
- (R.S) will complete obturation using AdSeal resin-based root canal sealer .

盲法说明
- The patients will drag an envelope and will not know to which group they will be assigned.
- The patients who already do not know their treatment group will assess the level of their post-operative pain and will record the number of analgesic tablets used.
- The laboratory technician at the microbiological department will not know the treatment group of the patients.
