Summary. Introduction. A review of the literature relating to supernumerary teeth is presented along with a survey of 152 cases.

Methods. The study population consisted of 152 children who visited the department of Paediatric Dentistry at the Jordan University Hospital. Patients ranged in age from 5 to 15 years. Supernumeraries were detected by clinical examination and radiographs.

Results. Males were affected more than females with a sex ratio of 2·2 : 1. Seventy-seven percent of the patients had one supernumerary tooth, 18·4% had double teeth, and 4·6% had three or more supernumeraries. Ninety percent of the supernumerary teeth occurred in the premaxilla, of which 92·8% were in the central incisor region and of these latter 25% were located in the midline. The other 10·4% of the supernumeraries were located in the premolar, canine, molar, and lower central incisor regions. Two cases were of non-syndrome supernumerary teeth. Seventy-five percent of the supernumeraries were conical, 83·1% were in the normal vertical position and 26·5% were erupted. Conical-shaped supernumerary teeth had a significantly higher rate of eruption compared to the tuberculate type.

Supernumerary teeth: review of the literature and a survey of 152 cases

Most supernumerary teeth are located in the anterior maxillary region. They are classified according to their form and location. Their presence may give rise to a variety of clinical problems. Detection of supernumerary teeth is best achieved by thorough clinical and radiographic examination. Their management should form part of a comprehensive treatment plan. This article presents an overview of the clinical problems associated with supernumerary teeth and includes a discussion of the classification, diagnosis and management of this difficult clinical entity.

Supernumerary teeth--an overview of classification, diagnosis and management.

Objective: The goal of this study was to evaluate the radiological and clinical findings of non-syndromic multiple (five or more) supernumerary teeth in patients radiographically examined between 1999 and 2004. Methods: Among 9550 patients, 251 cases of supernumerary teeth were found, including six cases of multiple supernumerary teeth. Patients with multiple supernumerary teeth were evaluated for age, sex, unilateral or bilateral distribution of the teeth, localization, morphology and complications or associated pathologies such as dentigerous cysts, eruption anomalies, resorption of adjacent teeth, displacement of tooth germ, malformation, migration, neurological symptoms, and secondary and periapical infections. Results: All patients were male and most of the multiple supernumerary teeth were seen in the premolar region. The prevalence of multiple supernumerary teeth was 0.06%. Out of 37 multiple supernumerary teeth examined, 30 were impacted. Various associated anomalies were seen in 21.6% of cases. A...

Characteristics and prevalence of non-syndrome multiple supernumerary teeth: a retrospective study

Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. They can cause a variety of complications in the developing dentition. This article reviews the epidemiology, clinical features, diagnosis and options for the management of supernumerary teeth. Clinical Relevance: Early diagnosis and appropriate management can minimize the potential complications caused by supernumerary teeth. Dental practitioners should be aware of their clinical signs and the treatment options. Dent Update 2008; 35: 510-520

Diagnosis and management of supernumerary teeth.

Dental anomalies are common congenital malformations that can occur either as isolated findings or as part of a syndrome. This review focuses on genetic causes of abnormal tooth development and the implications of these abnormalities for clinical care. As an introduction, we describe general insights into the genetics of tooth development obtained from mouse and zebrafish models. This is followed by a discussion of isolated as well as syndromic tooth agenesis, including Van der Woude syndrome (VWS), ectodermal dysplasias (EDs), oral-facial-digital (OFD) syndrome type I, Rieger syndrome, holoprosencephaly, and tooth anomalies associated with cleft lip and palate. Next, we review delayed formation and eruption of teeth, as well as abnormalities in tooth size, shape, and form. Finally, isolated and syndromic causes of supernumerary teeth are considered, including cleidocranial dysplasia and Gardner syndrome.
