Trauma resulting in crown-root fracture is one of the most challenging fracture types. However, biologic width involvement should be carefully evaluated. Reattachment of tooth fragment to a fractured tooth remains as the treatment of choice because of its simplicity, natural esthetics, and conservation of tooth structure. The reattachment procedure using composite resin should be considered if the subgingival fracture can be exposed to provide isolation. This report presents a case of complicated crown-root fracture of permanent maxillay left central incisor, involving the biologic width in a 10-year-old girl. The traumatized tooth was treated endodontically. Access to the subgingival margins was gained by orthodontic extrusion followed by gingivectomy. The fractured fragment was reattached using bonding system and composite resin.

The following case report describes a case of traumatic bone cyst (TBC) with classical clinical features occurring as a rare combination in a very young female patient with a traumatic etiology and its management using acrylic splint postsurgery.How to cite this article: Banda NR, Nayak UA, Vishwanath KH, Sharma DS, Khandelwal V. Management of Traumatic Bone Cyst in a 3-Year-Old Child: A Rare Case Report. Int J Clin Pediatr Dent 2012;5(3):213-216.

Most of the times paediatric patients report to the clinics with a chief complaint of decayed teeth, associated with pain and sometimes swellings, which regress after proper treatment. But dentist should be aware of unusual and rare pathologic conditions in children. These conditions sometimes are associated with hidden aggressive nature. These unusual and rare kinds of clinical conditions should also be included in differential diagnosis. Present case shows inadvertent finding of Unicystic Ameloblastoma (UA) in paediatric patient, which was asymptomatic and aggressive in nature. This case report shows diagnosis and surgical management of such type of lesions in paediatric patients.
