PerioChip® (chlorhexidine gluconate) is a small, orange-brown, rectangular chip (rounded at one end) for insertion into periodontal pockets. Each PerioChip weighs approximately 7.4 mg and contains 2.5 mg of chlorhexidine gluconate in a biodegradable matrix of hydrolyzed gelatin (cross-linked with glutaraldehyde). PerioChip also contains glycerin and purified water.
Chlorhexidine gluconate is an antimicrobial agent.
PerioChip is indicated as an adjunct to scaling and root planing procedures for reduction of pocket depth in patients with adult periodontitis. PerioChip may be used as a part of a periodontal maintenance program, which includes good oral hygiene and scaling and root planing.
