The periodontal ligament (PDL) injection: an alternative to inferior alveolar nerve block.

The periodontal ligament (PDL) injection for mandibular anesthesia in isolated regions was evaluated, using both a conventional syringe and two devices designed for this procedure. A high success rate was achieved, with a low incidence of adverse reaction and highly favorable comment from both patients and administrators. Duration of pulpal anesthesia following the technique described proved adequate for most dental procedures. The newer devices appear to have some advantage over the conventional syringe technique. However, the PDL injection technique can readily be used with any conventional syringe. Further study is recommended to determine the response of periodontal and pulpal tissues.

The Gow-Gates mandibular block. Evaluation after 4,275 cases.

The Gow-Gates mandibular block, introduced in the United States in 1973, represents the first new approach to intraoral regional anesthesia in many years. The technique is being taught at most United States dental schools. This article presents a clinical evaluation of the Gow-Gates technique after 5 years of application and more than 4,000 cases. Advantages of this technique over the conventional inferior alveolar nerve block include a greater success rate, decreased positive aspiration rate, and fewer postinjection problems.

Nitrous oxide sedation and sexual phenomena.

Nine cases of sexual phenomena that occurred with use of nitrous oxide and oxygen sedation are described. Dentists involved routinely used concentrations of nitrous oxide greater than 50% and did not have assistants in the room during dental procedures. Recommendations on the concentrations of nitrous oxide and the presence of an assistant are made.

Physical evaluation system to determine medical risk and indicated dental therapy modifications.

The physical evaluation system allows the practitioner to rapidly classify each patient according to medical risk and thus to provide dental treatment comfortably and safely. The evaluation system serves as a guide to the level of dental therapy, deisions of management, and modification of treatment for the medically compromised patient. Extensive use of the ADA physical status classification system in dentistry would allow meaningful studies of morbidity and mortality that are related to various management protocols and could conceivably have an impact on insurance schedules associated with psychosedation modalities and general anethesia on an out patient basis. A physical evaluation system cannot substitute for knowledge and good judgment. Recommended categories of physical status and modification of treatment should not be considered as absolutes, but as guides. Wheras the guidelines may appear to be inflexible, they should not be considered as such. Deviation from recommendations is often justified and is expected.

A comparison between articaine HCl and lidocaine HCl in pediatric dental patients.

PURPOSE: Three identical single-dose, randomized, double-blind, parallel-group, active-controlled multicenter studies were conducted to compare the safety and efficacy of articaine HCl (4% with epinephrine 1:100,000) to that of lidocaine HCl (2% with epinephrine 1:100,000) in patients aged 4 years to 79 years, with subgroup analysis on subjects 4 to < 13 years. METHODS: Fifty subjects under the age of 13 years were treated in the articaine group and 20 subjects under the age of 13 were treated with lidocaine. Subjects were randomized in a 2:1 ratio to receive articaine or lidocaine. Efficacy was determined on a gross scale immediately following the procedure by having both the subject and investigator rate the pain experienced by the subject during the procedure using a visual analog scale (VAS). Safety was evaluated by measuring vital signs before and after administration of anesthetic (1 and 5 minutes post-medication and at the end of the procedure) and by assessing adverse events throughout the study. Adverse events were elicited during telephone follow-up at 24 hours and 7 days after the procedure. RESULTS: Pediatric patients received equal volumes, but higher mg/kg doses, of articaine than lidocaine during both simple and complex dental procedures. Pain ratings: Articaine: VAS (Visual Analogue Scale) scores (from 0 to 10 cm) by patients 4 to < 13 years of age were 0.5 for simple procedures and 1.1 for complex procedures, and average investigator scores were 0.4 and 0.6 for simple and complex procedures, respectively. Lidocaine: patients 0.7 (simple) and 2.3 (complex); investigators 0.3 (simple) and 2.8 (complex). Adverse events: No serious adverse events related to the articaine occurred. The only adverse event considered related to articaine was accidental lip injury in one patient. CONCLUSIONS: VAS scores indicate that articaine is an effective local anesthetic in children and that articaine is as effective as lidocaine when measured on this gross scale. Articaine 4% with epinephrine 1:100,000 is a safe and effective local anesthetic for use in pediatric dentistry. Time to onset and duration of anesthesia are appropriate for clinical use and are comparable to those observed for other commercially available local anesthetics.

Anterograde amnesia as a possible postoperative complication of Midazolam as an agent for intravenous conscious sedation.

Anterograde amnesia is often considered to be a beneficial effect of intravenous conscious sedation. The recently introduced benzodiazepine, midazolam, has associated with its administration a significant anterograde amnesic period. In the case presented here, a healthy young female presented for third molar extraction under midazolam conscious sedation and local anesthesia. After uncomplicated removal of the teeth and clinically adequate recovery from sedation, it was noted that the patient had swallowed the postsurgical gauze packs. Efforts at recovery of the gauze packs were futile. Follow-up discussion with the patient revealed a complete lack of recall of all events occurring for up to an hour or more after the administration of intravenous midazolam. The need for written and oral postoperative instructions to both the patient and his/her escort is emphasized.
