Abstract
Introduction
The aim of this study was to evaluate pain perception, pain medication intake, and
sealer extrusion after single-visit root canal treatment of asymptomatic teeth with
or without foraminal enlargement. The correlation between sealer extrusion and pain
was also investigated.
Methods
One hundred forty necrotic, single-rooted teeth were divided into 2 groups (n = 70): foraminal patency (FP), in which treatment was performed up to 1 mm short
of the apex, and foraminal enlargement (FE), in which treatment was performed up to
the apex. The canals were instrumented using WaveOne Gold files (Dentsply Maillefer,
Ballaigues, Switzerland), irrigated with 2.5% sodium hypochlorite, and filled using
the single-cone technique and AH Plus sealer (Dentsply Maillefer). A visual analog
scale was used to record pain 24, 48, and 72 hours and 1 week postoperatively. The
presence or absence of sealer extrusion was recorded.
Results
Pain levels were significantly higher for FE than FP at 24 hours (P < .05), namely 0.3 ± 0.9 versus 0.1 ± 0.1; no difference was found at 48 hours, namely
0.1 ± 0.5 versus 0.0 ± 0.0 (P > .05). No pain was reported 72 hours or 1 week postoperatively in either group.
Although all patients requiring pain medication at 24 hours were from the FE group,
the difference between FE and FP was not statistically significant with respect to
this variable (P > .05). Nevertheless, the intake amount was significantly higher in FE than in FP
at this time point (P < .05). Sealer extrusion occurred more frequently in FE than FP, namely 57.14 % versus
14.29% (P < .05). There was no association between pain and sealer extrusion (P > .05) or between pain and sex, age, or tooth type (P > .05).
Conclusion
FE was related to higher pain levels 24 hours postoperatively and to higher rates
of filling material extrusion; however, there was no association between filling material
extrusion and postoperative pain.
