Local antibiotic therapy
In this form of antimicrobial periodontal treatment the dentist places the antibiotic medication directly into the affected mouth tissues. The material dissolves slowly releasing a controlled dose of the antibiotic for a period of a few days.
There are several types of local antibiotic therapy, including:
· Gel – A gel containing antibiotic is injected into periodontal pockets under the gums and sealed with a periodontal pack which is removed after 7 to 10 days along with any remaining gel.
o Atridox is such a gel containing doxycycline.
o Elyzol is a gel applied to the gum that is composed of metronidazole.
· Powder — The dentist places the antibiotic in the form of a powder under the gums. The powder dissolves in about three weeks.
· Chip - Chips containing antibiotic is placed under the gums and into the periodontal pockets. The chip dissolves over 7 to 10 days.
o Periochip is a small piece of gelatin filled with chlorhexidine.
o Actisite is a thread-like fiber similar to dental floss that contains tetracycline hydrochloride.
o Arestin contains tiny round particles with the antibiotic minocycline.
