Body
Objectives : The aim of this case report is to show how CBCT, in a radiographic strategy, can
help to organize the clinical management of dens evaginatus, or talon cusp, in a low cooperation
child of 6 years old.
Case report : a 6 years old child referred by an orthodontist consults for discomfort while
closing the buccal cavity. This appears to be linked to the presence of excess dental tissue
located behind the lingual side of the central left permanent incisor (21), which comes into
contact with the permanent antagonistic incisors. Given the presence of a premature occlusive
contact, as well as the immature status of the permanent incisors, we conducted a CBCT examination
in second intent (NewTom VGi®) in order to evaluate, on one hand, the morphology
of the anomaly, the possible links with 21, the pulpal network, the thickness and the level
of the vestibular cortical, and on the other hand, to orientate the surgical intervention. With
conscious sedation, the dental lamina was horizontally sectioned in order to eliminate occlusal
interference and to allow for a repositioning of 21. As this intervention exposed the pulpal
cusp, an apexogenesis was carried out extemporaneously with Mineral Trioxyde Aggregate
material and the coronary sealing was conducted. More than 18 months later, we observe the
absence of symptomology and the continuation of the radicular edification.
Conclusion : the CBCT allowed us to optimise the clinical mangement of a talon cusp by orienting
with certitude the treatment towards a conservative therapy.
