Pain control in dentistry is an important factor for reducing the fear and anxiety associated with dental procedures. For tooth extraction, it is mandatory to use resources to manage pain and discomfort such as adequate anesthetic techniques . Patient's systemic health conditions and type of local anesthetic drug used, in addition to duration and extension of the extraction procedure are factors which can influence the management of pain in tooth extractions .
Tooth extractions can cause morbidity and changes in hemodynamic parameters to the patient; therefore, it is paramount to carefully select a local anesthetic drug to minimize adverse events . There are a variety of local anesthetics drugs which can meet the specific requirements of different clinical procedures, among them 4% articaine chloridrate with epinephrine at a ratio of 1:100,000. and with and 3% mepivacaine chloridrate without epinephrine, which are largely used in the dental practice and whose clinical safety has already been tested and proved elsewhere
