Twisted files were used serially with a single controlled motion according to the manufacturer's instructions.

The root canals were cleaned and shaped using a #40 instrument for thin or curved canals and a #55 file for widespread canals.

WaveOne files was used to prepare narrow, straight and curved canals, and a file (40.08) was used for large and wide canals.

Reciproc instrument was used in thin and curved RC, and R40 files (40.06) were used in wide canals.

Relate Post-endodontic Pain

Twisted file adaptive SM1 (size 20, .04 taper) and SM2 (size 25, .06 taper) were used serially with a single controlled motion according to the manufacturer's instructions.

Twisted File Adaptive

Flex-R files sizes 15-45 taper .02 were used according to the technique

Balance Force

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.

WaveOne

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.

Post-endodontic Pain After Single-visit Root Canal Treatment

Use of Intracanal Cryotherapy on Post-endodontic Pain After Single-visit RCT Using Manual and Reciprocating Systems When Apical Patency is Conserved.

Relate the post-endodontic pain after single-visit After the root canal treatment with Balanced Force technique and three reciprocating system.

A final irrigation after root canal treatment was made with cold 3cc of (6oC) 17% EDTA gently delivered to the WL using a cold (6oC) sterile metallic micro cannula.

This clinical research took place at the University Autonomous of Baja California, School of Dentistry, Tijuana, Mexico. The subjects review committee accepted the research, and conducted in accordance with ethical principles (including the World Medical Association Declaration of Helsinki).

teeth selected for conventional RCT for prosthetic reasons detected with only vital pulps. Of the sample of 224 teeth, 56 were selected to the 4 instrumentation methods. For hand instrumentation, Balanced Force were used. All canals were clean and shaped with hand Flex-R files (fMoyco/Union Broach, York PA, USA). For mechanical shaping, all instruments were used with a micro motor (VDW, Munich Germany). Twisted files adaptive, WaveOne and Reciproc instruments. Final irrigation with cold (6oC) 17% EDTA served as a lubricant.

Certified endodontists trained in the procedures, devices, and systems investigated took part in the research. All experts tracked a pre-established procedure for the Balanced Force technique, Twisted File Adaptive, WaveOne, and Reciproc instrument systems.
