The management of supernumerary teeth in childhood ‐ a retrospective study of practice in Bristol Dental Hospital, England and Westmead Dental Hospital, Sydney, Australia

Abstract

This study compared the treatment provided for patients with supernumerary teeth in Bristol Dental Hospital with those in Westmead Dental Hospital, Sydney, Australia. The records of 63 children referred for removal of a supernumerary tooth in Bristol and 96 children in Westmead were examined, involving a total of 215 supernumerary teeth. Differences in the treatment provided for these patients were found not only between the two centres but also within one centre. There appeared to be no standardised route by which these patients were seen and therefore no standardised pattern of treatment. Contact with all UK Dental Schools indicated that no formal treatment protocol existed for the treatment of children with supernumerary teeth. In addition, a permanent incisor associated with a conical supernumerary tooth was twice as likely to erupt spontaneously as one associated with a supernumerary of tuberculate form. The location of the supernumerary tooth also influenced the likelihood of spontaneous eruption of the associated permanent incisor. There is a need for a prospective randomised controlled trial in the future in order to develop a formal treatment protocol for the management of patients with supernumerary teeth. A multicentre trial is under development.

Characteristics of nonsyndromic supernumerary teeth in children and adolescents

“…The boy-to-girl ratio of our study population was 1.94:1, and this is in agreement with previous studies that reported that boys are affected approximately twice as frequently as girls in cases of permanent dentition (1,3,5,6,17,20). However, Davis (14) reported a boy-togirl ratio of 6.5:1 in a study of Chinese children, whereas Bäckman and Wahlin (26) reported that girls had more ST than boys among 7-year-old Swedish children.…”

“…ST are considered to be one of the most significant dental anomalies affecting children and adolescents, and diagnosis and management of these teeth is one of the main responsibilities of dentists and also physicians (1)(2)(3)(4)(5).…”

“…Local and independent hyperactivity of dental lamina is the most widely accepted theory for the development of ST (1)(2)(3)(4)(5). Heredity may also play a role in the occurrence of this anomaly, as ST are more common in the relatives of affected children than in the general population (3,4,6).…”

Supernumerary Teeth: Review of the Literature with Recent Updates

“…Högström and Andersson [66] suggested two different opinions where the ST should be removed as early as upon identification or should wait until complete root formation of adjacent teeth. The optimal time for surgical intervention, however, remains contentious [78]. It is very important to remove ST at a young age if it is damaging adjacent teeth or causing any other complication.…”

Hiperodoncia múltiple y su relación con la displasia cleidocraneal

“…La terapéutica indicada para la hiperodoncia es quirúrgica complementando en algunos casos con aparatología ortopédica u ortodóntica, por esta razón el tratamiento debe ser multidisciplinario donde se integren diferentes campos como cirugía oral, ortopedia maxilar, ortodoncia y odontopediatría, para lograr una correcta planificación y manejo de la alteración, la terapia quirúrgica de los supernumerarios es importante porque estos se convierten en un obstáculo para la erupción de los dientes permanentes, alteran la alineación de los dientes en la arcada o pueden estar afectando la estética (12)(13)(14).…”
