Protocol summary

Study aim
The aim of this study is to evaluate post instrument pain after cleaning and shaping using Gentelfile(Tornado) system and comparing with Mtwo system.
Design
The patients are devided in 2 groups randomly by using a random number table. Each patient is assigned a 4-digit code, if the end digit on the right is 2.7,9, the patient is in Mtwo group, and if the final digit is 3,5,6, the patient is in Gentlefile group. The total sample size is 30 and the phase does not apply in this study.
Settings and conduct
The study population is people who visit Dr Reza Hatam office (endodontist) for molar root canal treatment. In this study, patients are evaluated for inclusion and exclusion criteria. Blindness is performed for the pain assessor and the patient. They have no information about the cleaning and shaping system.The assessor calls patients at specified intervals after treatment and asks them about post-treatment pain and taken analgesics(Ibuprofen 400mg).
Participants/Inclusion and exclusion criteria
Inclusion criteria is age 18 to 60 years old. Exclusion criteria is internal and external resorption,periodontal disease,retreatment cases,necrotic tooth,tooth with calcified canals,immature roots,systemic problems which have contraindication for root canal treatment.
Intervention groups
patients are randomly divided into 2 groups. Each group is treated with one of the Gentlefile(Tornado), Mtwo system. Each patient is assigned a code. Codes are kept in envelopes. The patient randomly selects one of the envelopes before entering. The specialist chooses the cleaning and shaping system based on the codes. The treatment steps in all 2 groups are exactly the same.The only difference is in the cleanning and shaping system used.
Main outcome variables
The amount of post endodontic treatment pain

General information

Reason for update
In this study, it was decided to compare three study groups and three interventions. These interventions included clearing and shaping the root canal with Mtwo rotary system, cleaning and shaping the root canal with Rotaper Gold rotary system, and cleaning and shaping the root canal with Gentlefile (Tornado) rotary system.Unfortunately, due to the corona epidemy and the decrease in the number of patients referred to the dental office and On the other hand, due to the lack of equipment for cleaning and shaping the root canal with Protaper Gold system, the group of researchers decided to remove the Protaper Gold group at the discretion of the Research Council of the School of Dentistry. Patient treatment is ongoing for the remaining two interventions. However, the intervention of cleaning and shaping the root canal with the Protaper Gold rotary system has been eliminated.
