title: [Arsenic trioxide resulting in alveolar bone chemical necrosis: report of 2 cases].
abstract: The most serious complication of arsenic trioxide devitalization of dental pulp is alveolar bone chemical necrosis because of iatrogenic perforation of pulp chamber and arsenic trioxide leakage. Arsenic trioxide is protoplasmic poison.When it contacts periodontal tissues, alveolar bone degeneration, necrosis and loss of bone will occur. When the dental of pulp chamber is open, the operator must pay attention to the length and orientation of the bur, with guidance of the dental X-ray film to avoid pulp chamber perforation.
