Abstract
A survey of 31 published cases and 11 original cases of vertical root fractures due to iatrogenic reasons revealed that most of the vertical root fractures in endodontically treated teeth occurred in mandibular bicuspids and molars in patients aged 41–60 years. The diagnosis of vertical root fracture is difficult because of the late appearance of the signs and the appearance of pure endodontic or periodontal problems. This survey revealed that the most common cause of vertical root fracture in endodontically treated teeth is the excessive force used during lateral condensation of gutta‐percha. Widening of the periodontal ligament along one or both sides of the root, or bone loss in solitary tooth are the major radiographic findings. Mild pain or discomfort and swelling are the major clinical symptoms, and solitary pocket around one aspect of the suspect tooth is the major clinical sign.
