AIM
To determine the functional diagnostics criteria for predicting the effectiveness of using 2% and 4% solutions articaine without vasoconstrictor and with epinephrine content of 1:200.000.
MATERIAL AND METHODS
The study involved 357 patients (193 women and 164 men) aged 20 to 35 years. with the presence of intact single-rooted and multi-rooted teeth without periodontal pathology without pronounced general somatic pathology, and with a low level of situational anxiety according to the Spielberger-Khanin scale. All the patients received injection anesthesia by the infiltration method of 2% and 4% articaine solution without vasoconstrictor or with epinephrine concentration of 1:200.000. The effectiveness of local anesthesia was assessed by recording functional parameters (electrosensitivity threshold test and hemomicrocirculation) of the pulp of intact single-root and multi-root teeth before anesthesia, 5, 10, 15, 30, and 60 minutes after local anesthesia. The safety of the anesthesia was determined by continuous monitoring of the patient’s hemodynamic parameters: blood pressure, heart rate, blood oxygen saturation before anesthesia and within 60 minutes after.
RESULTS
Articaine solution 2% with epinephrine concentration of 1:200.000 used for infiltration or modified periodontal anesthesia resulted in pulp electrosensitivity threshold growth by 95.93% and 93.58%, respectively. There were no statistically significant differences in hemodynamic values between both study groups.
CONCLUSION
Analysis of the data obtained showed the effectiveness and safe anesthesia with drugs based on 2% articaine with an epinephrine concentration of 1:200.000.
