This article aims to illustrate and discuss the risks of failing to treat a radicular cyst appropriately. Here we report a 23-year-old male patient who sustained dental trauma to his maxillary anterior teeth on more than one occasion. The changes involved with the patient's dentition and expansion of the radicular cyst across his maxilla, over the course of a decade, highlight the importance of early intervention and appropriate treatment.
Cystic development related to root fracture is an unusual dental occurrence.1 Radicular cysts account for approximately 54.6% of odontogenic cysts and tumours, and are the most common cystic lesion of the jaws.2 Sixty percent are reported in the maxilla, evidently linked to pulpal necrosis of anterior maxillary teeth due to the increased prevalence of both dental trauma and dens invaginatus.3 Often, radicular cysts develop slowly, painlessly and are detected via incidental or routine radiographic finding.4 The epithelial rests of Malassez (residual cells of the root sheath of Hertwig) in the periodontal ligament form the radicular cyst epithelial lining, with a number of theories proposed for the formation of epithelial cysts.5 The differential diagnosis of anterior maxillary cystic lesions of the jaw may include: radicular, residual or lateral peridodontal cyst, odontogenic keratocyst, globulomaxillary cyst, traumatic bone cyst and ameloblastoma.6 Despite being unable to differentiate between cystic and non-cystic periapical radiolucencies using radiographic evidence alone,7 the general consensus of a well circumscribed radiolucent area bordered by a thin radio-opaque line usually symbolizes a cyst.8
