The earliest known reported occurrence of dentigerous cyst in a six-month-old child.

The earliest reported case of the occurrence of a dentigerous cyst is described; the cyst surrounded an unerupted permanent tooth bud in a 6-month-old infant. Most commonly these lesions present between the second and third decades of life. They rarely occur before 10 years of age and have not been documented prior to 1 year of age. In the case reported here, the treatment instituted was extraction of the adjacent deciduous tooth and enucleation of the cyst along with the permanent molar tooth bud. Clinicians should be aware of the potential for this lesion to occur across a wide range of ages and the importance of prompt diagnosis and treatment to prevent complications and reduce morbidity.
