Evaluation of Postoperative Pain in Children

August 11, 2020 updated by: Alp Abidin Ateşçi, Ege University

Evaluation of Postoperative Pain and Instrumentation Time After Root Canal Treatment With Rotary and Reciprocal File Systems in Children - A Randomized Clinical Trial

Postoperative pain is a common symptom of a flare up after root canal treatments (RCTs). Insufficient instrumentation, extrusion of irrigation solutions and debris and existence of a periapical lesion are the factors affecting postoperative pain after root canal treatments. Aim of this study is to evaluate the postoperative pain and instrumentation time of single-file reciprocating system and multiple-file Ni-Ti rotary system in children ages between 9-12. Study was conducted on fifty first permanent mandibular molars with the diagnosis of irreversible pulpitis. Patients were randomly separated into two groups and RCTs were completed with either Reciproc Blue or Protaper Next file systems. Instrumentation time for each system was noted and patients were given a pain scale which included visual analog scale for 6, 24, 48 and 72 hours after treatment. Postoperative pain scores and instrumentation times were analyzed statistically with chi square test and student t test. There was no statistically significant difference in postoperative pain between Reciproc Blue and Protaper Next systems at all time intervals. Instrumentation time was significantly shorter in the Reciproc Blue group in comparison with the Protaper Next group. In conclusion, shorter treatment time of single-file reciprocating systems may be more patient friendly and comfortable than multiple-file rotary systems in RCTs among children.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Active Comparator: Protaper Next
Protaper Next group (n=25): The instrumentation of mesial and distal canals were done according to manufacturer's recommendations using X1 and X2 (25.06) at a rotational speed of 300 rpm. Then X3 and X4 (40.06) instruments were used to enlarge distal canals in order to compare the results with the Reciproc Blue group. The root canals were irrigated with 2 ml of %2,5 sodium hypochlorite after each instrument exchange.
Other: Evaluating Postoperative Pain After Root Canal Treatment with Protaper Next
Patients were randomly separated into two groups and root canal treatments were completed with Protaper Next file systems. Instrumentation time for each system was noted and patients were given a pain scale which included visual analog scale for 6, 24, 48 and 72 hours after treatment.Postoperative pain scores and instrumentation times were analyzed statistically with chi square test and student t test.

  • Root Canal Instrumentation
  • Root Canal Treatment
  • Assessing Postoperative Pain
  • Instrumentation Time
Active Comparator: Reciproc Blue
Reciproc Blue group (n=25) : The canals were shaped with in accordance with the manufacturer's recommendations. R25 (25.08) instrument was introduced into the canal with slow pecking movement within a 3 mm range each time. The flutes and remnants were cleaned after 3 pecking moves. Then R40 instrument (40.06) was selected to shape the distal canals as the #20 K file was passively introduced to the working length. The root canals were irrigated with 2 ml of %2,5 sodium hypochlorite after each instrument exchange.
Other: Evaluating Postoperative Pain After Root Canal Treatment with Reciproc Blue Files
