Iatrogenic Periodontal Injury Due to Pulp Devitalizer – A case report

The aim of this paper is to report clinical complications (pain, necrotic gingival tissue and bone sequestration) resulting from accidental spillage of pulp devitalizer. Paraformaldehyde based devitalizers are commonly used in endodontic treatment for pulp extirpation. This paper presents a case where accidental contact of paraformaldehyde with the interdental gingiva led to localized necrosis of the gingiva and interdental alveolar bone. Surgical intervention was required wherein the necrosed bone was removed and the bone defect was filled with bone graft. The flap was coronally repositioned and sutured securely. After the treatment, the patient's complaints had resolved. Spillage of the product was responsible for marked necrosis of the gingiva and the alveolar bone. Therefore, great care must be exercised while delivering of such products during treatment.
