1 1 Cartridge Components Dilutions and ConcentrationsPercent solution {Different anesthetics come in various concentrations {The concentrations are given as a = 5 mg/ccz1% = 10 mg/ccz2% = 20 mg/ccz3% = 30 mg/ccz4% = 40mg/ccCartridge Components {The prefilled dental Cartridge consists of four parts:zCylindrical glass tubezStopperzAluminum CapzDiaphragm{To determine the mg/ Cartridge , multiply the mg/cc by {How many milligrams of mepivacaine are contained within 2 cartridges of mepivacaine 3%?z3% mepivacaine = 30mg/ccz1 Cartridge = ccz2 cartridges = ccz(30 mg/cc)x( cc) = 108 mgConcentrations of Vasoconstrictor in Local Anesthetics1:50, mg/ml1:100, mg/ml1:200, mg/mlCalculation{1:50,000 = {1gram/50,000 ml ={1000mg/50,000ml = {1mg/50ml = {( mg/ml)x( ml/ Cartridge ) =.036 mg/ Cartridge {-OR-zthe way someone once explained it to me:{start with 1,000,000 (aka convert to g) and divide the ml amount of the concentration, this give you the concentration in MICROGRAMS/ml{1,000,000 g/50,000 = 20 g/ml{If you are looking for mg, instead of g, you can always divide by 1000 at this point (aka, move the decimal point to the left 3 places)2 Example{How much lidocaine in a Cartridge of lidocaine 2% with epinephrine 1/100,000?}}}}}}}}}}}}}}}
