Abstract :
Background: The purpose of this study was to determine the most painful site of infiltration
injection in the anterior part of maxilla.
Materials and Methods: This single?blinded clinical trial was conducted on thirty healthy
volunteers. The participants received three maxillary infiltrations injected at the region of central
and lateral incisors as well as canines at three separated appointments with a 2?week interval. The
outcome variable was pain that measured immediately after needle insertion (time = 0) and during
injection of anesthetic solution in 5, 30, and 55 s by a visual analog scale. Data were analyzed by
SPSS software version 16 using Friedman test.
Results: There was no statistically significant difference in terms of needle insertion pain and during
injection (time = 0, 5, 30, and 55 s) (P = 0.319, P = 0.849, P = 0.627, and P = 0.939, respectively) in
the three injection sites.
Conclusion: The pain intensity of infiltration was not associated with injection sites in the anterior
maxilla.
