Anxiety is a relevant problem in dental practice. The Visual Analogue Scale for Anxiety (VAS-A), introduced in dentistry in 1988, has not yet been validated in large series. The aim of this study is to check VAS-A effectiveness in more than 1000 patients submitted to implantology. ⋯ Our study confirms that VAS-A is a simple, sensitive, fast, and reliable tool in dental anxiety assessment. The rate of disagreement between VAS-A and DAS is probably due to different test sensitivities to different components of dental anxiety. VAS-A can be used effectively in the assessment of dental patients, using the values of 5.1 cm and 7.0 cm as cutoff values for anxiety and phobia, respectively.

Bispectral index monitoring (BIS) as a guide for intubation without neuromuscular blockade in office-based pediatric general anesthesia: a retrospective evaluation.
The Bispectral Index System is a useful guide for timing of adequate intubation conditions in office-based pediatric general anesthesia without neuromuscular blockade. As the number of cases in the office-based setting increase, many clinicians opt to intubate patients without neuromuscular blockade to avoid airway complications associated with skeletal muscle relaxation. Conventionally, this technique is conducted using the traditional monitoring criteria of vital signs, end-tidal inhalation agents, as well as anesthesiologist timing and knowledge of the pharmacodynamics of the anesthetic agent to help determine the proper depth of anesthesia for adequate intubating conditions. ⋯ The mean BIS value during the time of intubation was 34.7. There were no complications encountered. A BIS mean value of 34.7 provided adequate intubation conditions without muscle relaxation in office-based pediatric anesthesia without complications.

Randomized Controlled TrialEfficacy of anesthetic agents to delay pain onset after periodontal surgery.
The aim of this study was to evaluate the influence of 2 anesthetic agents on patients' postoperative pain perception after periodontal surgery. For this parallel-group, double-blinded, randomized clinical trial, 36 open flap debridement surgeries were performed on patients who presented with periodontal disease with clinical signs of inflammation after nonsurgical treatment on at least 1 quadrant. Patients were allocated to 1 of the following groups: group 1, 2% lidocaine with 1 ∶ 100,000 epinephrine; group 2, 2% mepivacaine with 1 ∶ 100,000 norepinephrine. ⋯ All patients received 750-mg acetaminophen tablets, which they were instructed to take as a rescue medication if necessary. The results demonstrated that postoperative pain intensity was statistically lower in group 2 than in group 1 at the 1-, 2-, and 3-hour periods after surgery, although the pain intensity for all groups could be considered mild. In conclusion, patients in both groups reported similar mild pain after periodontal surgery.

Bispectral index monitoring of sedation depth in pediatric dental patients.
The bispectral index (BIS) monitor records electroencephalogram waveforms and provides an objective measure of the hypnotic effect of a sedative drug on brain activity. The aim of this pilot study was to use the BIS monitor to evaluate the depth of procedural sedation in pediatric dental patients and to assess if the BIS monitor readings correlate with a validated pediatric sedation scale, the University of Michigan Sedation Scale (UMSS), in determining the level of sedation in these patients. Thirty-five pediatric dental patients requiring sedation were studied prospectively. ⋯ A lack of correlation was noted between the deeper levels of UMSS sedation scores and BIS values. This study demonstrated a significant correlation between BIS values and the UMSS score in pediatric dental patients undergoing mild to moderate sedation. Based on our results, it appears that the BIS monitor may be useful during mild or moderate sedations to establish the level of sedation objectively without the need to stimulate the patient.

Case ReportsTransient cardiac arrest in patient with left ventricular noncompaction (spongiform cardiomyopathy).
Left ventricular noncompaction (LVNC), also known as spongiform cardiomyopathy, is a severe disease that has not previously been discussed with respect to general anesthesia. We treated a child with LVNC who experienced cardiac arrest. Dental treatment under general anesthesia was scheduled because the patient had a risk of endocarditis due to dental caries along with a history of being uncooperative for dental care. ⋯ Thereafter, an opioid-based anesthetic was performed, and recovery was smooth. In LVNC, opioid-based anesthesia is suggested to avoid the significant cardiac suppression seen with a volatile anesthetic, once intravenous access is established. Additionally, all operating room staff should master Advanced Cardiac Life Support/Pediatric Advanced Life Support (including intraosseous access), and more than 1 anesthesiologist should be present to induce general anesthesia, if possible, for this high-risk patient.
