Bilateral supplemental deciduous canines with an associated unilateral supernumerary permanent canine

First report of bilateral supernumerary teeth associated with both primary and permanent maxillary canines

“…The causes of supernumerary teeth are poorly understood, although many theories have already been proposed, such as the phylogenetic process of atavism and the dichotomy of the tooth bud. The most accepted theory suggests that these teeth result from localized and independent hyperactivity of the dental lamina, which presumably leads to the formation of additional tooth germs (1)(2)(3)(4)(5). Genetics is also thought to play a role in the development of supernumerary teeth, as recurrence within the same family is commonly reported (6,7).…”

“…Although supernumerary teeth may occur either unassociated to any other anomaly or as part of developmental disorders, multiple supernumerary teeth are rare in individuals with no other associated diseases or syndromes (4,5). They can have rudimentary morphology or normal size and shape, the latter being called supplemental (1,2,4,5). They are more frequently seen in the maxillary region of the permanent dentition, especially the mesiodens, which is located in the premaxilla (3)(4)(5)(14)(15)(16)(17)(18).…”

“…The presence of supernumerary teeth may give rise to a variety of clinical problems, such as dentigerous cyst (23), malocclusion (23)(24)(25), root resorption (1,5,18), displacement or rotation (2,18,25), failure of eruption or delayed eruption of the adjacent tooth (2,18,23,26), esthetic disturbances (25), and others (1,5,15,18). Findings from surveys have shown that most supernumerary permanent teeth remain unerupted (4,18).…”

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

“…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.…”
