Design outcomes

Primary

MeasureTime frame
To investigate the incidence and levels of postoperative pain after endodontic treatments in a single session in teeth with pulp necrosis, with or without asymptomatic apical periodontitis, comparing different kinematics of rotary or reciprocating instrumentation, and limits of apical instrumentation with or without intentional foraminal enlargement. . Therefore, this multicenter prospective randomized clinical trial was designed to carry out this investigation—

Secondary

MeasureTime frame
It is expected to obtain the pain scores experienced by patients after 24, 48 and 72 hours for statistical analysis ;The patient's pain is assessed according to a verbal rating scale followed by a score. The information collected was recorded in a spreadsheet for subsequent statistical analysis—
