What This Study Did, in Plain Language
What Was Tested
Researchers studied Root Canal Therapy and Gutta-Percha in this randomized controlled trial publication.
The factors that influence postoperative pain after root canal treatment are not completely understood.
The purpose of this prospective clinical study was to evaluate postoperative pain after root canal therapy performed in 1 appointment versus 2 appointments.
Statistical analysis was performed to compare groups at each interval by using an independent-samples t test with Bonferroni adjustment.
Who Took Part
Seventy-two patients requiring root canal therapy on permanent molars were included in this study.
Patients were randomly assigned to either the 1-appointment or the 2-appointment group.
How the Study Was Run
The researchers set it up as a randomized study.
The participants were allocated by chance, so the Root Canal Therapy group and the comparison group should start out alike.
Both vital and nonvital teeth were included.
Teeth in group 1 (n = 39) were obturated at the first appointment by using laterally condensed gutta-percha and Roth 811 sealer.
Teeth in group 2 (n = 33) were closed with a sterile dry cotton pellet and Cavit restoration and were obturated at a second appointment 7 to 14 days later.
A modified Visual Analogue Scale was used to measure preoperative pain and pain at 6, 12, 24, and 48 hours after the first appointment.
What Was Measured
The subject headings attached to it are Appointments and Schedules, Calcium Sulfate, Dental Alloys, Dental Cements, Disinfectants, Drug Combinations and Gutta-Percha.
