EndodontologyEfficacy of articaine and lidocaine in a primary intraligamentary injection administered with a computer-controlled local anesthetic delivery system
Section snippets
Material and methods
Fifty-one adult subjects participated in this study. All subjects were in good health and were not taking any medication that would alter pain perception, as determined by a written health history and oral questioning. The Ohio State University Human Subjects Review Committee approved the study, and written informed consent was obtained from each subject.
Subjects randomly received intraligamentary injections of articaine and lidocaine solutions at 2 separate appointments spaced at least 1 week
Results
Fifty-one adult subjects, 25 men and 26 women from age 20 to 53 years with an average age of 26 years, participated.
Anesthetic success of the intraligamentary injection is presented in Table I. There were no significant differences between the articaine and lidocaine solutions. Incidence of pulpal anesthesia (80 readings) for the 2 anesthetic solutions are presented in Fig 1, Fig 2, Fig 3.
The onset of pulpal anesthesia is presented in Table II. There was a significant difference between the
Discussion
The use of no response to the 80 reading (maximum output of the pulp tester) as a criterion for pulpal anesthesia was based on the clinical studies of Dreven et al40 and Certosimo and Archer.41 These studies40, 41 showed that no response at the 80 reading ensured pulpal anesthesia in vital asymptomatic teeth. Additionally, Certosimo and Archer41 demonstrated that electric pulp testing readings less than 80 resulted in pain during restorative procedures.
