Surgical Orthodontic Treatment of an Impacted Canine in the Presence of Dens Invaginatus and Follicular Cyst

Abstract

Introduction. “Dens invaginatus” is a dental anomaly which originates from the invagination of the ameloblastic epithelium into the lingual surface of the dental crown during the odontogenesis. It can cause early pulpal necrosis, abscesses, retention or dislocation of contiguous elements, cysts, and internal resorptions. It normally affects the upper lateral incisors. In the following study the authors will discuss the etiology, the physiopathology, and the surgical-orthodontic management of a rare case of impacted canine associated with dens invaginatus and follicular cyst, with the aim of highlighting the importance of taking any therapeutic decision based on the data available in the literature. Case Report. The present study describes a combined surgical-orthodontic treatment of an impacted canine associated with a lateral incisor (2.2) suffering from type III dens invaginatus with radicular cyst, in a 15-year-old patient. Discussion. When treating a dens invaginatus there are different therapeutic solutions: they depend on the gravity of the anomaly and on the association with the retention of a permanent tooth. The aesthetic and functional restoration becomes extremely important when performing a surgical-orthodontic repositioning.

Dilated odontoma: an unusual case report and literature review

“…Eleven cases were related to maxillary teeth [3,4,6,8,9,[11][12][13][14][15][16]. Among them, nine were located in the anterior maxillary region [3,4,8,9,[11][12][13]15,16]. Our report presents an extremely rare case of DO localized in the anterior mandibule.…”

“…In our review, almost 60% of the cases involved women [1,5,7,[10][11][12][13][14][15]. Eleven cases were related to maxillary teeth [3,4,6,8,9,[11][12][13][14][15][16]. Among them, nine were located in the anterior maxillary region [3,4,8,9,[11][12][13]15,16].…”

“…In these cases, the use of computed tomography (CBCT) can be helpful. Among the 16 reported cases, computed tomography was used in eleven patients [1,[4][5][6][7][8][9]13,15,16]. In this case report, the CBCT allowed to rule out the diagnosis of odontoma and to identify a DO on the tooth 42.…”
