Postoperative Pain Comparison in Asymptomatic Irreversible Pulpitis: Manual Vs. Rotary Instrumentation

Abstract

Objective: The objective of this study was to compare the impact of manual and rotary instrumentation on postoperative pain in teeth diagnosed with asymptomatic irreversible pulpitis.

Material and methods: A total of 50 participants were enrolled in this study, with each group consisting of 25 incisors. The participants were selected based on the need for endodontic treatment due to asymptomatic irreversible pulpitis in the first or second molars of the mandible, all of which showed normal findings on periapical radiographs. The periapical images were processed using a specialized scanner and software interface, ensuring high-quality storage before being analyzed further with a digital radiography system. After the selection process, the participants were divided into two groups of 25 individuals each by a physician. Data analysis was done using SSPS software.

Results: In both cohorts, there had been noticed a substantial decrease in postoperative pain severity from the initial assessment to the final evaluation across all time points measured. Nevertheless, A comparative examination of pain intensity between the RaCe rotary group and the hand K-Flexofile group did not reveal any statistically significant differences. The mean pain severity scores recorded 4 hours post-treatment had been 27.14±5.32 for the RaCe group and 35.45±6.72 for the K-Flexofile group. Following 8 hours, the scores had been 25.11±4.78 for the rotary group as well as 30.63±3.84 for the hand file group. The rotary group demonstrated a reduction in pain severity at both time points when compared to the hand file group; however, the differences observed were not statistically significant.. Furthermore, at the twelve-hour, twenty-four-hour, forty-eight-hour, and seven-day intervals, the variations in pain severity among the 2 cohorts remained insignificant.

Conclusion: The rotary group exhibited a reduction in pain severity at both time points compared to the hand file group; however, the differences were not statistically significant
