Multiple Supernumerary Teeth in a Nonsyndromic 12-Year-Old Female Patient - A Case Report

Abstract

Supernumerary teeth (ST) are uncommon alterations of development that may appear in either of the dental arches and that are frequently associated with syndromes such as cleidocranial dysplasia and Gardner syndrome. Multiple ST in individuals with no other disease or syndrome are very rare. In view of this situation, correct diagnosis, treatment and evaluation of ST with the use of appropriate imaging techniques are highly important. This case report presents radiographic images of a nonsyndromic 12-year-old female patient who presented with 14 supernumerary teeth and was treated under general anesthesia, with the extraction of all ST in a single surgical intervention. During the postoperative period, the patient did not complain of pain nor did she present any signs or symptoms of infection. During late follow-up period, due to difficulty in traction of the maxillary right canine and mandibular left first premolar towards the dental arch, it was necessary to extract these teeth under local anesthesia. Radiographic examination 3 years after surgery revealed the absence of ST and of diseases related to the existence of these teeth.

Non syndromic supernumerary teeth: management of two clinical cases

“…In contrast, multiple supernumerary teeth have been found to occur more frequently in the premolar region [ 4 ,8]. The literature shows that 76 to 86% of non-syndromic cases involve only one supernumerary tooth and that 12 to 23% of cases present two ST [ 2 , 3 , 9 , 10 ]. Analysis of ST cases shows that the variation is small, with the presence of one or two ST being more frequent.…”

“…While single tooth impaction is not uncommon, development of multiple impacted teeth is a rare condition and often found in association with syndromes or developmental anomalies such as cleidocranial dysplasia, Gardner's syndrome, trichorhino phalangic syndrome and cleft lip and palate [ 1 ]. Multiple ST in individuals with no other disease or syndrome is very rare [ 2 ]. In addition, they can occur unilaterally or bilaterally and can arise in the maxilla, mandible, or both [ 3 ].…”

Cleidocranial dysplasia: description with emphasis on the radiographic aspects of three cases in a family

“…[11][12][13][14][15][16][17] A incidência de dentes supranumerários na população comum é estimada em 0,2-5,3%, com predomínio no gênero masculino (54-82%), porém quando presentes em múltiplos sítios estão altamente associados a condições sistêmicas ou sindrômicas, incluindo as síndromes de Gardner, de Nance-Horan, de Ehlers-Danlos, de Fabry, tricorrinofalangeana, de Ellis-van Creveld e de Robinow. 18,19 Os ossos wormianos estão presentes em aproximadamente 8-15% dos indivíduos, entretanto esse número pode ser próximo de 80% na população chinesa. Cerca de 50% desses ossos ocorrem na sutura lambdoide e 25% na coronal, sendo mais comuns no lado direito.…”

Four Fourth Molars

“…3 Nonsyndromic supernumerary teeth are uncommon entities and when present they often present singly and not in multiple numbers. 5 Apart from causing a disturbance in the eruption and position of the adjacent teeth, supernumerary teeth increase the risk of pathological conditions, such as ameloblastoma, follicular cyst, and fistulae. 13 This fact is a significant factor in deciding the management of supernumerary teeth.…”

“…3,4 In the absence of any syndromes, occurrence of multiple supernumerary teeth is rare. 5 Supernumerary teeth are classified according to the morphology as conical, tuberculate, supplemental, and odontome; as per the position as mesiodens, distomolars, paramolars, or parapremolars. 6 Of these, conical form is the most commonly found form in permanent dentition, presenting usually as a mesiodens.…”
