Non‐syndromic multiple supernumerary teeth transmitted as an autosomal dominant trait

Abstract

Supernumerary teeth are common in the general population and occur more frequently in-patients with family history of such teeth. Multiple supernumerary teeth are associated with cleidocranial dyplasia and Gardner syndrome. However it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. We describe the occurrence of multiple supernumerary teeth in a family occurring as a non-syndromal trait. The autosomal dominant transmission of non-syndromal multiple supernumerary teeth is new.

Non-Syndromic Multiple Supernumerary Teeth in a Child: A Rare Case Report

“…Surgical management is commonly and acceptable in literature, despite this kind of treatment may cause damage in adjacent structures [1]. The patient needed orthodontic treatment, therefore, in this case the surgical indication was clear.…”

“…Which reported only nine supernumerary teeth in your study. In the prior literature, MST were presented mainly in the maxilla with slight predilection for man gender, however in this case, the major number of supernumerary teeth were presented in the mandible of a girl (9) and only five in the maxilla [1][2][3]5].…”

“…Therefore, other classification is according to the intraoral position of the tooth: 1) Mesiodens, 2) Paramolar, 3) Distomolar, and 4) Parapremolar [4,5]. The prevalence rate of MST varies on population from 0, 1 to 3, 6% [1]. The main morphology of MST reported in the prior literature is conical shape, followed by tuberculate and supplemental [5].…”

“…Multiple supernumerary teeth (MST) has been reported in the literature over the years as well-recognized phenomenon and it has defined by tooth number excess compared with deciduous or permanent dentition [1,2]. Generally, supernumerary teeth present morphology and volumetric anomalies which can be erupted or nonerupted [3,4].…”

“…MST is a common condition, when the patient has Cleidocranial Dysplasia or Gardner Syndrome. However, MST is rare in non syndromic patients [1,3,4].…”
