Ultacan

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.[3] Contents 1 History 2 Structure and metabolism 3 Clinical use 4 Contraindications 5 Paresthesia controversy 6 References 7 External links History This...
