Retrospective Study of Characteristics and Treatment of Dentigerous Cysts Involving the Maxillary Anterior Tooth

The aim of the present study was to identify the clinical characteristics and treatment outcomes associated with maxillary anterior dentigerous cysts in children. Among 55 patients who had been diagnosed with maxillary anterior dentigerous cysts, 33 patients had cysts located in the incisor region and 22 had cysts located in the canine region. Cysts in the incisor region were 7.2-fold more prevalent in male patients, while cysts in the canine region were 1.75-fold more prevalent in female patients. For cysts in the incisor region, marsupialization was performed in 21 cases and enucleation in 12 cases. In the canine region, marsupialization was performed in 20 cases and enucleation in 2 cases. Spontaneous eruptions of the displaced teeth in the incisor and canine region were 90% and 54.5%, respectively. Among patients which spontaneous eruption occurred, patients with cysts in the incisor region underwent orthodontic treatment more often due to malocclusion. This study is expected to be used as fundamental data for establishing future treatment plans by providing the analyzed results of distribution and characteristics of dentigerous cysts involving the maxillary anterior tooth.
