Eight hundred and fifty-one claims submitted to the Swedish Patient Insurance Scheme were studied and analysed. The most frequent claim referred to root fractures of roots with posts, and to root perforations also related to root posts. Other relatively frequent claims referred to pulpal complications in connection with fixed prosthodontics, root perforations related to endodontic treatment, and dysaesthesia. The mean latency time (the time from the actual treatment to the diagnosis of the injury) was for root fractures 10.6 months, and the mean latency time for root perforations that were not directly observed during preparation was 15.9 months. Pulpal complications of teeth treated with crowns or fixed partial dentures had a mean latency time of 7.6 months. Injuries with a low frequency were, for example, fracture of vital abutments for crowns or fixed partial dentures, damage to tissue by electrosurgery or to the floor of the mouth by drilling, or perforations to the antrum. Two cases of particles dropped into the patient's eye were also reported.
对提交给瑞典患者保险计划的851份索赔申请进行了研究和分析。最常见的索赔涉及带桩根的根折，以及与桩相关的根穿孔。其他相对常见的索赔涉及固定修复相关的牙髓并发症、与根管治疗相关的根穿孔以及感觉异常。根折的平均潜伏期（从实际治疗到损伤诊断的时间）为10.6个月，在预备过程中未直接观察到的根穿孔的平均潜伏期为15.9个月。用冠或固定局部义齿治疗的牙齿的牙髓并发症的平均潜伏期为7.6个月。低频损伤包括，例如，冠或固定局部义齿的重要基牙骨折、电外科对组织的损伤或钻孔对口腔底部的损伤，或上颌窦穿孔。还报告了两例颗粒掉入患者眼睛的病例。
