The Effect of Foraminal Enlargement of XXXX with the Reciproc System on @entity282 : A Prospective and Randomized Clinical Trial.

@entity1 @entity282 @entity158 @entity39
INTRODUCTION: The aim of this prospective study was to evaluate the @entity282 that followed root canal treatments performed with a single-file reciprocating system on asymptomatic @entity39 teeth with and without foraminal enlargements (FEs). METHODS: Forty-six volunteers were randomly divided into 2 groups according to the established working lengths. The FE group had a working length of 0.0  mm from the apex, and the control group had a working length of 1.0  mm short of the apex. The treatments of both groups were performed with a Reciproc R40 (VDW, Munich, Germany) instrument. Both groups underwent the same treatment protocol with the exception of the established working length. The volunteers were instructed to record their @entity158 (none, mild, moderate, or severe) on a visual analog scale at 24  hours, 72  hours, and 1 week after the procedures. The Kruskal-Wallis test was used to identify significant differences. RESULTS: Overall, 82.22% of the @entity1 indicated no @entity158 or mild @entity158 . A greater proportion of the @entity1 in the FE group reported mild @entity158 compared with @entity1 in the control group in the first 24  hours  (P  <  .05). At 72  hours and 1 week, there were no statistically significant differences between the groups (P  >  .05). CONCLUSIONS: FEs during endodontic treatments of asymptomatic @entity39 , uniradicular teeth that were performed in single visits using the Reciproc R40 reciprocating file resulted in a low incidence of @entity158 . After 24  hours, the FEs resulted in more @entity1 reporting mild @entity158 compared with the control group, but no differences were observed at 72  hours or 1 week.
