Although it is well known that prolonged application or leakage of arsenic trioxide can cause severe damage to the periodontal tissues, the substance is still used by some dentists. This paper describes a case of arsenical necrosis of the jaws affecting the right and the left side of the maxilla. As a result of leakage into the tissues of an arsenical paste from the pulp chamber of endodontically treated teeth, bilateral oroantral fistula (OAF) occurred. It is concluded that there is no justification, whatsoever, for the use of arsenic in modern dental practice. In the following case, buccal advancement flap and submucosal palatal island flap techniques were used for to close the OAF. The submucosal palatal island flap technique resulted in successful closure of the OAF.
尽管众所周知，三氧化二砷的长时间应用或渗漏会对牙周组织造成严重损害，但一些牙医仍在使用这种物质。本文描述了一例影响上颌左右两侧的颌骨砷中毒性坏死病例。由于经牙髓治疗的牙齿髓腔内的砷糊剂渗漏到组织中，导致双侧口腔上颌窦瘘（OAF）。得出的结论是，在现代牙科实践中，没有任何理由使用砷。在以下病例中，采用颊向推进瓣和腭部黏膜下岛状瓣技术来关闭口腔上颌窦瘘。腭部黏膜下岛状瓣技术成功关闭了口腔上颌窦瘘。
