Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For hand instrumentation, the Balanced Force technique was used. All root canals were shaped with hand Flex-R files (Moyco/Union Broach, York PA, USA). Gates-Glidden drills (Dentsply Maillefer) sizes #2 and #3 were used at the orifice of the root canals. For mechanical preparations, all instruments were used with a micro motor (VDW Silver Motor, VDW, Munich Germany). Torque and rotation were preset for each Reciproc or WaveOne instrument. Rotary Ni-Ti instruments were used in continuous brushing rotary motion and reciprocating mode respectively.
Dentinal debris was eliminated from the file with a gauze, instantaneously to the instrument change (WaveOne) or after 2-3 in-and-out (pecking) movements (Reciproc) following the manufacturers' recommendations. Each root canal was irrigated with 2.5mL 2.6% NaOCl. Irrigation was performed using a 24-gauge needle (Max-I-Probe; Tulsa Dental, York, PA) and a 31-G NaviTip needle (Ultradent Products Inc, South Jordan, UT) when reaching the WL after each instrument insertion.
Group BF. For the Balanced Force group, the root canals were shaped and shaped using a #40 instrument for thin or curved canals and a #55 file for wide canals.
Group WON. For the WaveOne group, a file size 25/.08 was used to prepare narrow, straight and curved canals, and a file size 40/.08 was used for large and wide canals.
Three in-and-out pecking motions were used with an amplitude of not more than 3 mm until reaching the estimated working length.
Group REC. The R25 (size 25/ .08) instrument was used in thin and curved root canals, and R40 files (40/ .06) were used in wide root canals. Three in-and-out pecking motions were used with an amplitude of not more than 3 mm until reaching the estimated working length.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group BF
The root canals were cleaned and shaped using a #40 instrument for thin or curved canals and a #55 file for widespread canals.
Balanced Force technique
Flex-R files sizes 15-45 taper .02 were used according to the technique on each tooth
WaveOne technique
WaveOne instrument was used to prepare narrow, straight and curved canals, and file (40.08) was used for large canals.
Three in-and-out motions were used with lengths not beyond 3 mm in the three thirds of the canal until reaching the estimated WL.
Reciproc technique
Reciproc files were used in wide canals. Three in-and-out motions were used with lengths not beyond 3 mm in the three thirds of the canal until reaching the estimated WL.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* absence of radiographic sign of apical periodontitis and a diagnosis of irreversible pulpitis (IP) established by affirmative response to hot and cold examinations.
* Thermal pulp examination was achieved by the corresponding author, and radiographic analysis was established by 3 certified endodontists.
* Clinical requirements were established on the next conditions: 1) The purposes and necessities of the research were spontaneously accepted. 2) Clinical Management was pointed to patients in physical and mental well-being. 3) All teeth had vital pulps and absence of apical periodontitis. 4) Positive thermal stimulation with EndoIce (Hygenic Corp, Akron, OH). 5) Teeth with enough coronal structure for rubber dam isolation. 6) No RCT done before the research. 7) No painkillers or antibiotics used 7 days' prior the clinical events started
Exclusion Criteria
* the necessity for retreatment
* gravidity
* impossibility to obtain patient's approval
* patients who didn't complete inclusion necessities
* a history of medication for chronic pain or those compromising the immune response
* patients younger than 18 years and the existence of mishaps or difficulties during RCT (calcified canals, impracticality of achieving AP in any canal).
