PerioStōm is an FDA-cleared, non-drug, proprietary formulation of chitosan microspheres intended for the protection of oral mucosa due to irritation, trauma, or following iatrogenic procedures such as scaling and root planing.

The shellfish proteins are removed through a chemical process to derive chitin and chitosan. We have not seen any literature pointing to an allergic reaction to chitosan due to its protein content, and to the contrary, several studies have shown that those with a shellfish allergy did not have a reaction when exposed to chitosan. It is advisable to state that chitosan is originally derived from shellfish, and we leave it to clinicians and their patients to make the final decision.

The iodine found in shrimp is mostly in their organic tissue, not in the chitin of their exoskeleton. Therefore, when chitin is extracted and processed into chitosan, the iodine that was present in the shrimp's flesh is not retained in the chitosan.

PerioStōm is deposited near or at the base of the periodontal pocket. Upon delivery, it absorbs saliva and turns into a bioadherent gel which dissolves over time.

There has been very little published data on the use of chitosan and pregnancy or nursing. We leave it to clinicians and their patients to make the final decision on using PerioStōm when pregnant or nursing.
