Long-Term Treatment of Dentigerous Cyst Developing as a Result of Incorrect Total Amputation of Primary Tooth

Aim Cysts are pathological formations lined with epithelium that may show different characteristics depending on the epithelial tissue from which they originate, filled with liquid or semi-liquid material, showing localized development, usually with a connective tissue wall. Dentigerous cysts are often associated with impacted teeth and are benign developmental lesions. Rarely, they may occur due to inflammatory causes. Our aim was to report the management of inflamatuar dentigerous cycst related with total amputation in mixt dentition. Case Report In this case report, we present the three-year clinical follow-up after surgical marsupialization of an eight-year-old young patient who applied to our clinic with a complaint of swelling in the lower jaw. Discussion Inflammatory dentigerous cysts could occur in immature permanent teeth as a result of inflammation from a non-vital primary tooth. In cases of dentigerous cysts in children, various appliances and methods can be used for marsupialization. Marsupialization consists of uniting the cyst lining to the oral mucosa. This method has fewer complications than enucleation regarding the preservation of important anatomical structures and developing tooth germs. Conclusion Although the development of odontogenic cysts in children is rare, their formation and progression can be much more rapid and aggressive than in adults. In the treatment of lesions observed in childhood, marsupialization has been reported to be an effective treatment method for the protection of erupting permanent teeth and surrounding tissues.
