Effect of ProTaper Ultimate and ProTaper Gold on Postoperative Pain in Mandibular First Molars With Symptomatic Irreversible Pulpitis and Symptomatic Apical Periodontitis: A Randomized Control Clinical Trial.

OBJECTIVE

To compare and evaluate the effect of ProTaper Ultimate root canal instrumentation on postoperative pain level of mandibular first molars showing symptomatic irreversible pulpitis and symptomatic apical periodontitis.

METHODOLOGY: Forty patients referred to root canal treatment of the mandibular first molar were randomly divided into two equal groups according to the rotary file system used in the chemomechanical preparation: ProTaper Ultimate (n = 20) and ProTaper Gold (n = 20). After evaluating the preoperative pain score using the visual analog scale, the root canal treatment was performed in a single visit using a standardized protocol by a single operator. Postoperatively, the pain scores were recorded at 24-, 72-h, and 7-day intervals. Statistical analysis was performed at a significance of 0.05.

RESULTS

No significant difference was shown between the ProTaper Ultimate and the ProTaper Gold groups in the intensity of postoperative pain at all time intervals. The postoperative pain score was zero at 7 days postoperatively for both groups.

CONCLUSION

The ProTaper Ultimate files' effect on postoperative pain is equivalent to that of the ProTaper Gold files.

CLINICAL RELEVANCE: The ProTaper Ultimate files' effect on postoperative pain is equivalent to that of the ProTaper Gold files. ProTaper Ultimate and ProTaper Gold rotary file systems can be equally and safely used in single-visit root canal treatment.
