RESUMEN
AIM: The analysis of the criteria for predicting the effectiveness and safety of the use of periodontal anesthesia methods in the treatment of dental caries was carried out. MATERIALS AND METHODS: The study involved 78 patients: 41 women and 37 men aged from 25 to 56 years without severe somatic pathology, who needed treatment for dental caries. Intraligamental and modified periodontal anesthesia using a 4% articaine solution with different concentrations of vasoconstrictor were used as methods of anesthesia. The «method of the local injection anesthesia of the tooth pulp evaluating¼ was used during the modified periodontal and intraligmental anesthesia which determines the criteria for predicting the effectiveness and safety of the planned anesthesia and which is based on determining the functional parameters of the tooth pulp such as electrical excitability and microcirculation. RESULTS: The obtained results demonstrated the high efficiency and safety of the modified periodontal anesthesia with 4% articaine with epinephrine 1:200 000, which is easier to use and does not require specialized equipment. CONCLUSION: Modified periodontal anesthesia is safe and effective for the treatment of dental caries.
