BACKGROUND Two commonly used methods of digital nerve block with local anesthetic are the two-injection dorsal technique and the single-injection volar subcutaneous technique. The authors compared these two digital block techniques with respect to local anesthetic injection pain and recipient preference of anesthetic technique. METHODS Twenty-seven volunteers had the long finger of each hand ...

PURPOSE Presently, no standardized technique exists to monitor injection pressures during peripheral nerve blocks. Our objective was to determine if a compressed air injection technique, using an in vitro model based on Boyle's law and typical regional anesthesia equipment, could consistently maintain injection pressures below a 1293 mmHg level associated with clinically significant nerve injur...

We study the strength of certain obfuscation techniques used to protect software from reverse engineering and tampering. We show that some common obfuscation methods can be defeated using a fault injection attack, namely an attack where during program execution an attacker injects errors into the program environment. By observing how the program fails under certain errors the attacker can deduc...

In this paper, we propose a new technique that uses fault injection to reverse-engineer a private block cipher implemented with an unknown S-box. The private algorithm we wish to retrieve differs from a known algorithm in the choice of the S-Box, which we find using a novel, fault-injecting technique. The main idea is to consider the components of the S-Box as the solutions of a linear boolean ...

introduction: inferior mandibular bolck anesthesia, some time causes postoperative lip and tongue biting trauma, however, an infiltration injection with a limited anesthetized area, has less complications. the aim of present study is to compare of two techniques (block and infiltration) for class i restorative treatment in primary second molars. methods and materials: fourty children between 5-...

BACKGROUND AND AIMS Dentists administer thousands of local anesthetic injections every day. Injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. Accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicity,...

Background: Finger injuries are a common chief complaint in the emergency department (ED) and primary care setting. Repair of these injuries often require digital anesthesia through performing a digital nerve block (DNB). The two-injection subcutaneous volar block (SVB) and a two-injection dorsal digital block (DDB) are two of the most prevalently performed digital blocks in practice today. Thi...

Local anaesthesia makes the patient and dentist comfortable to do treatment with least amount of discomfort, but dental patient’s most frequent fear is receiving local anaesthetic injections. The present study attempted evaluate compare perception pain, pressure discomfort induced by three types injections (Infiltration, mental nerve block inferior alveolar injection) for mandibular anaesthesia...
