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.
