The use of the 80 reading as a criterion for pulpal anesthesia was based on the studies of Dreven et al and Certosimo and Archer. These studies showed that no patient response to an 80 reading ensured pulpal anesthesia in vital asymptomatic teeth. Additionally, Certosimo and Archer demonstrated that EPT readings less than 80 resulted […]

Twenty-three males and 7 females from age 19 to 43 years (average 24 years) participated in this study. One hundred percent of the subjects had subjective lip and tongue anesthesia with the IAN blocks. The discomfort ratings of solution deposition for the IAN blocks are presented in Table 1. There were no significant differences (P > .05) between the solutions.

Thirty adult subjects participated in this study. The subjects were in good health and were not taking any medications that would alter pain perception. The Ohio State University Human Subjects Review Committee approved the study, and written informed consent was obtained from each subject.

The inferior alveolar nerve (IAN) block is the most frequently used injection technique for achieving local anesthesia for mandibular restorative and surgical procedures. However, the IAN block does not always result in successful pulpal anesthesia. Failure rates of 8 to 67% have […]

After removal of the patch, the site of application was examined to evaluate the area for signs of irritation. No tissue discoloration, swelling, or sloughing was noted in association with patch application in any of the patients. In addition, no drug-related […]

Although plasma levels of local anesthetic are usually low in adults, plasma concentrations can be an important concern in the delivery of local anesthetics to children. The dose as a proportion of total body weight in the adult is relatively small, and thus the chance of local anesthetic toxicity is low. However, in children, particularly when premedicated with sedative drugs, the systemic effects of local anesthetic can be toxic. […]

This study was approved by the institutional review board of Columbus Children’s Hospital. Eligible subjects were selected from children scheduled for operative dentistry under general anesthesia at the Children’s Hospital Outpatient Surgery Center. These children had exhibited disruptive behaviors during routine dental appointments, thus requiring general anesthesia for comprehensive dental care. Eligible patients were those children who were healthy (ASA I), weighed over 12 kg, and were 2-7 years old. […]
