comparison of pain scale after single-visit root canal treatment by different temperatures and concentrations of NaOCl in mandibular molars with irreversible pulpitis: Double-blind randomized clinical trial

comparison of pain scale after single-visit root canal treatment by different temperatures and concentrations of NaOCl in mandibular molars with irreversible pulpitis

A clinical trial with the control group, with parallel groups, double-blind, randomized, phase 2 on 72 patients. RandList software will be used for randomization.

In this study, 72 patients at the endodontics department of Tabriz Dental School who have mandibular molars with irreversible pulpitis, will be selected and will be divided into 6 groups of 12. These groups will vary in terms of detergent concentration and room temperature. After treatment of the mandibular molar root of each group, the effect of detergent concentration and temperature on pain reduction will be investigated.

Inclusion: Systemically healthy patient, Patient age 18-65 years Lack of sensitivity to epinephrine and sodium hypochlorite, No facial paraesthesia, Do not take any painkillers 12 hours before treatment Do not take any medication that interferes with anesthesia, No history of trauma, Absence of pathological envelope during probing Completion of an ethical questionnaire and willingness to participate in the study, Lower molar teeth with irreversible pulpitis Exclusion: No lip anesthesia after 15 minutes of block injection, Pain for no reason before treatment, Pregnancy and lactation, Severe periodontal disease Teeth that can not be isolated with my brush, Calcification of the urethra, Teeth with severe irreparable caries, Use of a specific drug or medication

Patients requiring treatment of mandibular molars with irreversible pulpitis that has been treated and the effect of sodium hypochlorite at different temperatures and concentrations on the severity of patients' pain will be investigated.

Intensity of pain

All stages of treatment will be performed in Tabriz Dental School. These 72 people are randomly assigned to the 6 groups mentioned using RandList software. All random numbers are written on a piece of paper. The sheets are folded and placed in a container. For each number, one of the groups is selected. The syringes containing the washing solution are covered with a layer of opaque coating. Each patient chooses a sheet and uses one of the detergents for that patient based on the selected number. Thus, neither the patient nor the researcher is aware of the type of treatment chosen and the study will be double blind.

Thus, neither the patient nor the researcher is aware of the type of treatment chosen and the study will be double blind. To blind the study, all steps of sodium hypochlorite solution preparation will be performed by a trained assistant who has no role in the clinical process, and to prevent the researcher from feeling the temperature of the washing solutions, an insulating coating will be used on the washing syringes.
