Cardiovascular effects of maxillary infiltration of articaine and lidocaine with epinephrine in restorative procedures

The aim of this study was to evaluate cardiovascular effects by maxillary infiltration using 2% lidocaine with 1:100.000 epinephrine, 4% articaine with 1:100.000 and 1:200.000 epinephrine in different stages of dental appointment for restorative procedures. Twenty healthy patients randomly received 1,8 ml of the three local anesthetics. Systolic blood pressure, average blood pressure, diastolic blood pressure and heart rate were evaluated by the oscillometric and photoplethysmograph methods in seven stages of the appointment. Statistical analysis by ANOVA and Tukey tests of cardiovascular parameters did not show significant differences between the anesthetic associations. There were significant differences for the parameters among different clinical stages of the dental appointment. The variation of cardiovascular parameters is similar for articaine and lidocaine solutions and it is influenced by the stages of the dental appointment.
