Abstract
BACKGROUND: Arsenic oxide compounds were traditionally used as devitalizing agents. Due to its toxicity, leakage of such compounds into the periodontium can cause gingival and osteo-necrosis. Their use is forbidden in Europe and the USA for decades, however, some dentists seem to still use it. CASE REPORT: We report the case of a 14-year-old girl referred to the paediatric dentistry department of Toulouse University hospital, France, presenting a bone necrosis following the use of an arsenic trioxide product to accelerate pulp necrosis. TREATMENT: The treatment included surgical removal of necrosis bone sequestrum, complete pulpectomy and an intermediate restoration of the tooth 27. FOLLOW-UP: After 1 week, the clinical conditions greatly improved. A restoration using a ceramic crown was performed after 2 months, and complete healing was observed after 1 year follow-up. CONCLUSION: Although arsenic trioxide is neither appropriate nor permitted for use in modern dentistry, especially in paediatric dentistry, some rare cases of arsenic-induced osteo-necrosis can still be encountered. A clearer message must be given to all dental practitioners against the use of arsenic trioxide in modern endodontic treatment.
