Triple Antibiotic Paste is a type of Intra Canal Medicament which is used in Endodontic Treatment or
Root canal Treatment to kill the micro organisms in the periapical region of an infected Root Canal.
Triple antibiotic Paste or (TAP) consists of three medicines - Metronidazole, Ciprofloxacin and Minocycline. This combinati on of medicines have been found to be the best regimen to eliminate root canal pathogens. The most common microorganisms found in infected Root Canals are Peptostreptococcus spp, Actinomyces, Staphylococcus Salivarius, S. Sanguis, P. Endodontalis. The micro organisms most commonly infecting Failed or Re-infected root canals are "
Enterococcus Faecalis".
Triple Antibiotic paste uses: It is used as an
Intracanal Medicament and in
Regenerative Endodontics (Pulp Capping). It has been found to be very effective against E Feacalis which is a very stubborn bacteria found in Re-infected root canals.
Composition of Triple antibiotic Paste: TAP is a combination of three antibiotics -
Minocycline + Ciprofloxacin + Metronidazole. A combination of three antibiotics is required as any Infection of the Root Canal consists of multiple microorganisms of different types and to treat all these bacteria any single Antibiotic is sometimes not enough. A Combination of Antibiotics usually helps in treating the diverse flora of the Root Canal.
How is Triple Antibiotics Paste prepared:
Hoshino et al. first proposed the combination of TPA and mentioned that the three Antibiotics -
Metronidazole (500 mg) 30% + Minocycline (100mg) 30% + Ciprofloxacin (200mg) 30% + Propylene Glycol paste 10% should be mixed in a ratio of
1:1:1. These three components should have a carrier Glycol and macrogol ointment in a ratio of
1:1. The combination was later modified by making changes in the Ratios by Takushige et al. who proposed that the ratios should be Metronidazole + Minocycline + Ciprofloxacin -
3:3:1. A new Intra Canal Medicament known as
MTAD was found to be useful in eliminating
Enterococcus Faecalis strains in a study published by Newberry et al. The MTAD is a combination of 3% Doxycycline, Citric Acid and a detergent polysorbate 80. MTAD should be used as an irrigation fluid inside the canals. MTAD should be used as the final irrigation rinse after using 1.3% Naocl and Saline. This has been found to remove the smear layer without altering the structure of dentinal tubules.
