[Comparative analysis of 2% and 4% articaine solution efficacy and safety for the local anesthesia]. / Sravnitel'nyi analiz primeneniya 2% i 4% rastvora artikaina pri in"ektsionnoi mestnoi anestezii.

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.

[Preventive analgesia for the improvement of local anesthesia efficacy in treatment of acute pulpitis in molars]. / Ispol'zovanie preventivnoi anal'gezii dlya povysheniya effektivnosti mestnogo obezbolivaniya pri lechenii ostrykh pul'pitov molyarov.

THE AIM OF THE STUDY: Was the assessment of the efficacy of using non-steroidal anti-inflammatory drug Ketorol Express as a preventive analgesia in the treatment of acute pulpitis in molars. MATERIALS AND METHODS: The study comprised 128 individuals, 76 (59.4%) women and 52 (40.6%) men. The mean age was 37.4 years. Two different visual-analog scales were used to evaluate the effectiveness of pain relief and the general well-being of the patient and the doctor. THE RESULTS: Of the study proved that the preventive analgesia with Ketorol Express at a dosage of 20 mg 15 minutes before local anesthesia with 4% articaine with epinephrine 1:200 000 in patients diagnosed with acute pulpitis of molars was effective since local anesthesia high effectiveness, absence of necessity for alternate anesthesia were registered by patients, which coincided with the dentist's opinion. CONCLUSION: Preventive analgesia with Ketorol Express improves the efficacy of local anesthesia in the treatment of acute pulpitis in molars.
