Unilateral Fusion of Maxillary Lateral Incisor: Diagnosis Using Cone Beam Computed Tomography

Abstract

Objective. The objective of this paper is to report a dental fusion case focusing on clinical and radiographic features for the diagnosis. Method. To report a case of right maxillary lateral incisor fusion and a supernumerary tooth, the anatomy of the root canal and dental united portion were assessed by cone beam computed tomography (CBCT). Results. The clinical examination showed dental juxtaposition with the absence of interdental papilla and esthetic impairment in the right maxillary lateral incisor region. The periapical radiography did not provide enough information for the differential diagnosis due to the inherent limitations of this technique. CBCT confirmed the presence of tooth fusion. Conclusion. CBCT examination supports the diagnosis and provides both the identification of changes in tooth development and the visualization of their extent and limits.

Management of non-syndromic double tooth affecting permanent maxillary central incisors: a systematic review

“…The number of roots and anatomy of the pulp chamber and radicular pulp can be diagnosed only radiographically. Since 2D periapical radiographs cannot be totally conclusive for the diagnosis, CBCT should be systematically performed in all cases because it provides 3D dental imaging to help determine the best treatment 78 79. However, we found only four case reports (6%), published in 2003, 2010, 2012 and 2014, in which the authors performed CBCT 13 47 67 71.…”

“…Nevertheless, periapical radiographs represent two-dimensional (2D) dental imaging and cannot be accurate and conclusive 25 77. CBCT is an interesting alternative because it provides 3D dental imaging 78 79. With double tooth, CBCT can reveal the level of the union of the double tooth and the number of roots, the anatomy of the pulp chamber (single vs 2 separate chambers) and the anatomy of the radicular pulp (single vs 2 or more pulp canals).…”

Concrescence in Anterior Teeth Assessed by Cone Beam Computed Tomography. A Case Report

“…The incidence of unilateral double teeth is approximately 0.2% in a full adult dentition [ 15 ]. In this case report, the union of the root structures was only by the cement tissue, thus a dental concrescence in the anterior region was obtained [ 16 ].…”

“…The treatment of dental anomalies often requires surgery approaches that include dental extraction and dental sectioning. Orthodontic treatment is often necessary to correct function and esthetics, but in cases where the tooth misalignment is not as severe, a restorative approach should be considered due to its less invasive treatment plan 7 , 15 .…”

Management of non-syndromic dens evaginatus affecting permanent maxillary central incisors: a systematic review

“…Therefore, CBCT should be systematically performed. CBCT provides 3D dental imaging and can help determine the best treatment 49 50. CBCT allows for visualising any pulpal extension into the dens evaginatus.…”
