Comparative Evaluation of Postoperative Pain and Clinical Success

• This randomized clinical study was conducted to evaluate and compare the effects of the conventional step-back technique with hand files, the reciprocal technique with WaveOne Gold files, and the rotary technique with ProTaper Ultimate files on the frequency and intensity of pain before and after emergency treatment, as well as on clinical and radiological outcomes in symptomatic and acutely painful vital molars during root canal treatment. Sixty-three symptomatic mandibular molars with vital pulp were randomly allocated into three groups according to the preparation system used: Hand files, WaveOne Gold, and ProTaper Ultimate. The file systems assigned to each group were used for root canal preparation in all cases. In the rotary and reciprocating file groups, obturation was performed with their own gutta-percha using the single cone technique with Bioceramic sealer and in the conventional hand file group root canal obturation was performed with cold lateral compaction method.
