We report on two undiagnosed horizontal root fractures of two maxillary right central incisors in two different patients caused by dental trauma which occurred several years ago. These fractures were discovered during a routine full-mouth radiographic examination. While, in case one, the fracture was located in the middle-third of the root, it was in the cervical-third of the root in case two. The fractured teeth were observed to have healed spontaneously without any sign or symptom, and tested as vital to electric pulp test.
我们报告了两例不同患者上颌右侧中切牙未被诊断出的水平根折病例，这两颗牙因数年前的牙外伤所致。这些骨折是在常规全口影像学检查中发现的。在病例一中，骨折位于牙根中三分之一处，而在病例二中，骨折位于牙根颈三分之一处。观察到骨折牙齿已自发愈合，无任何体征或症状，牙髓电活力测试显示牙髓活力正常。
