What are the classification of local anesthesia?
A- Ester group:
1- Cocaine (seldom used)
2- benzocaine (used in topical anesthesia)
3- procaine (seldom used,short acting only for 30 minutes)
B- amide group:
1- lignocaine (lidocaine, xylocaine, octocaine, dentocaine)
⁃ it is the most commonly used local anesthetic agent in dentistry
⁃ Used in topical anesthesia
⁃ 2% lidocaine used in the dental cartridge
2- mepivacaine
⁃ short acting 45-75 minutes
⁃ 3% mepivacaine used in the dental cartridge
3- bupivacaine
⁃ long acting 180 minutes or longer
⁃ 0.5% bupivacaine used in the dental cartridge
5- prilocaine
⁃ Medium acting 90-150 minutes
⁃ 4% prilocaine used in the dental cartridge

What are the composition of local anesthetic agent in the cartridge?
1- local anesthetic drug (lidocaine)
2- vasopressor/ vasoconstrictor agent (epinephrine)
3- preservative for vasoconstrictor antioxidant (sodium bisulfite)
4- isotonic solution (sodium chloride)
5- distilled water
6- general preservation (methylparaben)

What is the deference between amide and ester?
- Amide metabolized in live
- Ester metabolized in blood
