Abstract

The aim of this study was to assess the attitudes of junior dental students at a United Kingdom dental school regarding the administration and receipt of a local anesthetic injection. The effect of teaching on these attitudes was also evaluated. Data were collected by questionnaire. Previous experience with local anesthesia in a dental office did not affect students' attitudes toward administration and receipt of a local anesthetic injection from a classmate. Female students were more anxious about giving and receiving local anesthetic injections than male students. Didactic teaching decreased anxiety in relation to administration and receipt of a local anesthetic injection. The results showed that male and female students in a United Kingdom dental school differed in their attitudes toward local anesthesia.

Abstract

The purpose of this study was to compare the effectiveness of intramuscular and intranasal midazolam used as a premedication before intravenous conscious sedation. Twenty-three children who were scheduled to receive dental treatment under intravenous sedation participated. The patients ranged in age from 2 to 9 years (mean age, 5.13 years) and were randomly assigned to receive a dose of 0.2 mg/kg of midazolam premedication via either intramuscular or intranasal administration. All patients received 50% nitrous oxide and 50% oxygen inhalation sedation and local anesthetic (0.2 mL of 4% prilocaine hydrochloride) before venipuncture. The sedation level, movement, and crying were evaluated at the following time points: 10 minutes after drug administration and at the times of parental separation, passive papoose board restraint, nitrous oxide nasal hood placement, local anesthetic administration, and initial venipuncture attempt. Mean ratings for the behavioral parameters of sedation level, degree of movement, and degree of crying were consistently higher but not significant in the intramuscular midazolam group at all 6 assessment points. Intramuscular midazolam was found to be statistically more effective in providing a better sedation level and less movement at the time of venipuncture than intranasal administration. Our findings indicate a tendency for intramuscular midazolam to be more effective as a premedication before intravenous sedation.

Abstract

A vibrating dental local anesthesia attachment (Vibraject, LLC, Calif) based on the concept of the gate-control theory has been used in clinical practice. The theoretical advantage of the vibrating needle is that it reduces the injection pain. We evaluated the effectiveness of Vibraject in combination with an electrical injection device. Injections were given into the alveolar mucosa adjacent to the root apex of the maxillary lateral incisor in 10 volunteers. Vibraject was randomly applied to either the left or right side of the injection. No statistically significant decrease in pain scores was found at needle insertion or anesthetic injection. The clinical efficacy of Vibraject remains controversial.

Effects of Local Injection of Prilocaine-Felypressin on the Myocardial Oxygen Balance in Dogs

Felypressin (Fely) is a synthetic hormone with a structure similar to that of arginine vasopressin. This drug is considered to have less influence on the cardiovascular system than epinephrine; therefore, it is often recommended for patients with cardiovascular diseases. However, some reports had described that both Fely and arginine vasopressin at clinical doses induce myocardial ischemia. The authors investigated the effects of Fely, a nonadrenergic vasoconstrictor, used together with prilocaine, which contains 3% prilocaine and 0.03 IU/mL Fely (Pri-Fely), on myocardial oxygen balance.
