WebArticaine. Articaine is a dental amide -type local anesthetic. It is the most widely used local anesthetic in a number of European countries [2] and is available in many countries. It is the only local anaesthetic to contain a thiophene ring, meaning it can be described as 'thiophenic'; this conveys lipid solubility.
