Background:  The aim of this study was to evaluate the cardiovascular effects of maxillary infiltration using 2% lidocaine with 1:100 000 adrenaline, 4% articaine with 1:200 000 adrenaline, and 4% articaine with 1:100 000 adrenaline in different stages during restorative dental procedures.

Methods:  Twenty healthy patients randomly received 1.8 mL of the three local anaesthetics. Systolic blood pressure, average blood pressure, diastolic blood pressure, and heart rate were evaluated by the oscillometric and photoplethysmograph methods in seven stages during the appointment.

Results:  Statistical analysis by ANOVA and Tukey tests of cardiovascular parameters did not show significant differences between the anaesthetic associations. There were significant differences for the parameters among different clinical stages.

Conclusions:  The variation of cardiovascular parameters was similar for lidocaine and articaine with both adrenaline concentrations and showed no advantage of one drug over the other. Cardiovascular parameters were influenced by the stages of the dental procedures, which showed the effect of anxiety during restorative dental treatment.
