Gingival and mandibular bone necrosis caused by a paraformaldehyde-containing paste.
A paraformaldehyde preparation (Toxavit) was applied to an inflamed and symptomatic pulp of the mandibular right first molar (tooth #46), in a 30-year-old woman. Leakage from the product was responsible for marked necrosis of the gingiva and the alveolar cortical bone, which resulted in loss of the tooth.
