___
Chlorhexidine chip
INTRODUCTION
It is a resorbable controlled local delivery adjunctive treatment to RSI for the treatment of periodontitis.
COMPOSITION
It is a biodegradable film of hydrolyzed gelatin containing 2.5mg of chlorhexidine.
SHAPE AND DIMENSIONS
One end of the chip is curved and should be placed in the apical direction.

The site to be treated is isolated and dried. Isolation is important as the contact with moisture renders the chip sticky and makes placement difficult. The chip with the help of a flat plastic instrument can be used to place the chip fully to the base of the pocket.

It is a controlled local delivery system and delivers chlorhexidine to the site at a concentration of 0.125micrograms/ml for 7-10 days
