Plasma cell gingivitis due to an antitartar toothpaste: An unusual case report

Abstract

Plasma cell gingivitis is a rareform of atypical gingival inflammation which is characterized by erythematous marginal gingival hypertrophy which may involve the adjacent attached gingiva. Plasma cell gingivitis (PCG) is an atypical form of gingivitis and is characterized by massive infiltration of plasma cells into the subepithelial connective tissue. It is a rare condition; the cause of which is still not fully understood. It is often attributed to an allergic reaction to the components of chewing gums, dentifrices or various diet components. A case of PCG is presented here in a 52-year old male who switched to an anti-tartar toothpaste on the advice of a dentist which manifested in a generalized form. This report is the first, as far as we know, that relates PCG to the use of Glister toothpaste manufactured by Amway. The histological examination revealed the infiltration of polyclonal plasma cells. The PCG disappeared within two weeks of stopping the use of the dentifrice.
