A non-syndrome case with bilateral supernumerary canines: report of a rare case

Abstract

Supernumerary teeth are described as the teeth formed in excess of the normal dental formula. Prevalence of supernumerary teeth varies between 0.1% and 3.8% in general Caucasian population. They have been reported in both the primary and the permanent dentition. Supernumerary teeth may occur in any region of the dental arch. However, a supernumerary tooth in the canine region is a rare condition and to our knowledge, a non-syndrome case with bilateral supplemental maxillary canines did not exist in the literature. It was the aim of this report to evaluate this rare case in view of both oral radiology and orthodontics.

Aesthetic and functional rehabilitation of a supernumerary peg-shaped tooth in the primary dentition

“…Another important fact to consider is that supernumerary primary teeth may undergo natural eruption and exfoliation 8 . On the other hand, this anomaly can also be associated with aesthetic 11 and occusal 5 changes. The technological advance of composite resins and adhesive systems allows professionals more and more to use minimally invasive techniques [20][21] .…”

“…Moreover, supernumerary teeth in the primary dentition may erupt and exfoliate naturally 8 . Nevertheless, this anomaly may be accompanied by aesthetic 11 and occlusal 5 changes, eruption failures and delays 12 , and even tumors 3 . Considering that early diagnosis and appropriate treatment of development changes are essential for occlusal, aesthetic, and functional congruence, the objective of this article was to report a clinical case involving the functional and aesthetic rehabilitation of a supernumerary peg-shaped tooth in the anterior maxillary region of a preschooler.…”

Bilateral mandibular supernumerary canines: a case report

“…Türkkahraman et al 6 reported a case, and Cho et al 11 described two cases of bilateral supernumerary maxillary canines. Sasaki et al 2 reported a patient with four supernumerary teeth; bilateral supernumerary maxillary canines and supernumeraries in the mandibular canine-premolar region.…”

“…Numerous developmental disorders also are associated with hyperdontia; cleft lip and palate, 6 and the following syndromes: Apert, Angio-osteohyper-trophy, cleidocranial dysplasia, craniometaphyseal dysplasia, Crouzon, Curtius, Down, Ehlers-Danlos, Fabry-Anderson, Fucosidosis, Gardner, Hallermann-Streiff, Klippel-Trenaunay-Weber, Laband, Nance-Horan, Oral-facial-digital type I and III, Sturge-Weber, and Tricho-rhino-phalangeal. 5 Defined Mutations are associated with the cleidocranial dysplasia, Gardner’s and Nance-Horan syndromes, 18 but no mutations in association with non syndromic supernumerary teeth have been identified yet.…”

“…Supernumerary teeth may occur in any region of the dental arch, 6 with 90-98% of occurrences in the maxilla. 4 90% of supernumerary teeth occur in the premaxilla region, 93% of which are in the central incisor region and 25% located in the midline.…”
