Aims: To assess the effect of alkalization of local anesthetic solution for the purpose of enhancing its
efficiency in periapical surgery. Materials and Methods: A total sample of 80 patients, all needing
periapical surgery on one or more of their upper anterior tooth (teeth) was subjected to this trial. For the
purpose of comparison, the sample was randomly divided into two groups based on the local anesthetic
solution that they were to receive before surgery. The first group(control) included those patients who
received the commercially available local anesthetic solution with a standard pH of 3.5.The second
group (trial group) included those patients who received a pH adjusted local anesthetic solution at 7.2
(using sodium bicarbonate).Prior to, and at the completion of intended surgery, the following data
were recorded: Pain during injection, onset of achievement of surgical anesthesia, pain during
operation and the duration of operation itself. Results: A significant difference in regard to onset of
achievement of surgical anesthesia between both groups was noticed with a faster onset in group two where the patients received a pH adjusted local anesthetic solution when compared to control group where the patients received the commercially available local anesthetic solution. Also, less pain on deposition of solution was noticed in the second group as well as less pain score levels were recorded during operation in regard to the same group. Conclusion: The pH adjusted local anesthetic solutions
may provide certain advantages when compared to the commercially available local anesthetic solutions regarding enhancement of anesthetic efficiency, reduced pain on injection as well as during surgery.
