Pulp obliteration is a very rare occurrence that is most frequently caused by trauma. A 58-yr-old female patient had a generalized pulp obliteration that involved all maxillary and mandibular teeth. One tooth was extracted due to an extensive carious lesion and it was processed by a cutting-grinding technique. It was possible to observe the complete obliteration of the pulp chamber, which was filled in part by reparative dentin and in part by a calcified tissue with a concentric layers structure with no tubular pattern. The root canals were almost completely obliterated by an amorphous calcified material.
牙髓腔闭塞是一种非常罕见的情况，最常见的原因是外伤。一名58岁女性患者出现全口牙髓腔闭塞，累及所有上颌和下颌牙齿。一颗牙齿因广泛龋损而被拔除，并采用切割研磨技术进行处理。可以观察到牙髓腔完全闭塞，部分被修复性牙本质填充，部分被具有同心层结构且无管状形态的钙化组织填充。根管几乎完全被无定形钙化物质闭塞。
