RESUMO
OBJECTIVE: The aim of this study was to (1) observe the extent to which hemodynamic and glucose measurements change in patients submitted to a dental procedure with and without a local anesthetic and a vasoconstrictor (LAVA; 2 percent mepivacaine with adrenaline 1100,000) and (2) correlate those parameters with the patients' anxiety levels. METHOD: This was an unblinded, random, prospective, and observational study with paired groups. Patients were evaluated during two different consultations during which they either did or did not receive a local anesthetic/vasoconstrictor. RESULTS: Thirty-seven patients ranging in age from 18 to 45 years (mean 30.4 ± 5.5 years) were evaluated. Hemodynamic parameters, including systolic blood pressure, diastolic blood pressure, heart rate, and glucose levels, did not change significantly in healthy patients, regardless of whether a LAVA was administered during the dental treatment. CONCLUSION: The patients' anxiety statuses neither varied significantly nor showed any correlation with the studied hemodynamic parameters and glucose levels, regardless of whether local anesthetics were used.
