Supernumerary teeth are those that are additional to the normal complement. They may occur in any region of the dental arch and have been reported in both the primary and the permanent dentitions. The etiology of supernumerary teeth is still not clearly understood, but several theories have been suggested for their occurrence. The investigated material were the remains from the Bácsalmás-Óalmás burial site (from the 16th-17th centuries), where 472 skeletons were excavated from 1993 to 2003. For the purpose of this study, the dentitions of 164 adult individuals were examined. The examination was carried out using macromorphological methods, radiographic analysis and a dial caliper were applied. This paper describes a supernumerary tooth of an adult female skeleton. On the labial surface of the first mandibular premolar an extra tooth was observed.Radiographic examination of the fused teeth indicated that the crown of the premolar had fused incompletely with the crown of the extra tooth. The position of the extra tooth could have been the result of gemination of the tooth germ or the elaboration of the buccal cingulum. The cranium of the examined individual showed some mongoloid morphologic features, too. Our presumption about the formation of the supernumerary tooth may have contributed to the theories of the occurrence of supernumeraries. The sporadic occurrence of this anomaly was reported in recent and archaeological skeletal collections. This study showed that multiple permanent dental formation was present in past Hungarian populations, representing a contribution to the history of dental anomalies.

A supernumerary tooth (ST) is defined as any tooth or odontogenic structure that is formed from tooth germ in excess of usual number for any given region of the dental arch. They may be single or multiple and unilateral or bilateral in distribution and can occur in any region of the dental arch. These may occur in primary and permanent dentition. Supernumerary teeth are more frequent in males. They are classified based on form, morphology, location, and occurrence. Several hypotheses have been proposed to explain the occurrence of ST. However, combination of environmental and genetic factors has been proposed. Supernumerary teeth cause a range of complications like crowding, displacement, dilacerations, cyst formation, and so forth. Early identification and appropriate treatment plan should minimize the potential complications caused by ST.

Impaction of maxillary central incisors is frequent in dental practice. However its management is challenging because of its importance in aesthetics. Supernumerary teeth are the most common dental anomaly that can cause impaction of adjacent teeth, crowding, diastema, rotation and displacement of teeth. We report a case of 13 year old male with an impacted supernumerary tooth in the maxillary anterior region, which was interfering with the eruption of the permanent, left central incisor. The impacted supernumerary tooth was surgically removed. With the application of an orthodontic traction, impacted left maxillary central incisor was brought down to its proper position in the dental arch.

The aim of this study was to characterize dental anomalies. The pretreatment records (photographs and radiographs) of 2897 patients (41.4% males and 58.6% females) were utilized to detect dental anomalies. The dental anomalies studied were related to number, size and shape, position, and eruption. A Chi-square test was carried out to detect associations between dental anomalies, jaw, and sex. A total of 1041 (36%) of the subjects manifested at least one dental anomaly. The prevalence of all dental anomalies was jaw-dependent and greater in the maxilla, except for submerged and transmigrated teeth. The most frequently missing teeth were the maxillary lateral incisor (62.3%) and the mandibular second premolars (60.6%). The most frequent supernumerary teeth were the incisors in the maxilla (97%) and the first premolars in the mandible (43%). Dental anomalies are more frequent in the maxilla and mainly involve the anterior teeth; in the mandible, however, it is the posterior teeth. These differences can be attributed to the evolutionary history of the jaws and their diverse development patterns.

The mammalian dentition is a serially homogeneous structure that exhibits wide numerical and morphological variation among multiple different species. Patterning of the dentition is achieved through complex reiterative molecular signaling interactions that occur throughout the process of odontogenesis. The secreted signaling molecule Sonic hedgehog (Shh) plays a key role in this process, and the Shh coreceptor growth arrest-specific 1 (Gas1) is expressed in odontogenic mesenchyme and epithelium during multiple stages of tooth development. We show that mice engineered with Gas1 loss-of-function mutation have variation in number, morphology, and size of teeth within their molar dentition. Specifically, supernumerary teeth with variable morphology are present mesial to the first molar with high penetrance, while molar teeth are characterized by the presence of both additional and absent cusps, combined with reduced dimensions and exacerbated by the presence of a supernumerary tooth. We demonstrate that the supernumerary tooth in Gas1 mutant mice arises through proliferation and survival of vestigial tooth germs and that Gas1 function in cranial neural crest cells is essential for the regulation of tooth number, acting to restrict Wnt and downstream FGF signaling in odontogenic epithelium through facilitation of Shh signal transduction. Moreover, regulation of tooth number is independent of the additional Hedgehog coreceptors Cdon and Boc, which are also expressed in multiple regions of the developing tooth germ. Interestingly, further reduction of Hedgehog pathway activity in Shhtm6Amc hypomorphic mice leads to fusion of the molar field and reduced prevalence of supernumerary teeth in a Gas1 mutant background. Finally, we demonstrate defective coronal morphology and reduced coronal dimensions in the molar dentition of human subjects identified with pathogenic mutations in GAS1 and SHH/GAS1, suggesting that regulation of Hedgehog signaling through GAS1 is also essential for normal patterning of the human dentition.

Maxillary Region

Supernumerary teeth are teeth in excess of the normal series occurring in any region of the dental arch. They are located mostly in the anterior maxillary region and are classified according to their location and morphology. The tuberculate type of supernumerary tooth possesses more than one cusp or tubercle (barrel shaped). It is rare to find bilateral tuberculate supernumerary teeth in the premaxillary region and when found they rarely erupt. This report describes a 13-year-old boy with erupted palatally placed bilateral tuberculate supernumerary teeth. The presence of these supernumerary teeth led to the labial displacement and rotations of the anterior maxillary teeth. The treatment involved extraction of the supernumerary teeth and a referral for orthodontic management of the crowding, displacement and rotations. The occurrence of erupted palatally placed tuberculate anterior teeth in this case is a rare experience. However, the associated orthodontic problems are within familiar spectrum.

Congenitally Missing

ABSTRACT Congenitally missing teeth are one of the most common dental anomalies which may be termed as dental agenesis. Polygenesis, the formation of one or more supernumerary teeth, occurs much less frequently than agenesis. Hypodontia and hyperdontia are regarded as the opposite dental developmental anomalies. However, their simultaneous presence in the same individual is a rare condition. A case of concomitant hypo-hyperdontia (CHH) is presented here, wherein a 20-year-old female has missing mandibular central incisors, maxillary second molars, and all the third molars. In addition, she has a malformed supernumerary tooth in the mandibular left anterior region. Documentation of such rare case reports is necessary as it helps in minimizing the clinicians' challenge in diagnosing such cases and thus helpful in providing a multidisciplinary approach in treating such patients.

And Function

Supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch .Mesiodens is the most common type of supernumerary tooth found in the premaxilla between two central incisors. They may be single, multiple, unilateral or bilateral, erupted or unerupted in one or, both jaw. It usually results in oral problems such as malocclusion, food impaction, poor aesthetics, and cyst formation. Early diagnosis and treatment is suggested to prevent orthodontic and pathologic complications. This article highlights the orthodontic management of a case of twenty five year old Bangladeshi male with two supernumeraries- one is a supplemental tooth erupted in the oral cavity causing malocclusion and another impacted mesiodens near the nasal floor. The case was managed by a joint effort of maxillofacial surgeon and orthodontist. At first, maxillofacial surgeon removed the two supernumerary teeth. After healing the orthodontic correction was done with fixed appliance using multiloop edgewise technique. It took nearly 18 months to complete the treatment. The patient was happy with the new appearance and function. DOI: http://dx.doi.org/10.3329/bjodfo.v2i1.16002 Ban J Orthod & Dentofac Orthop, October 2011; Vol-2, No.1, 30-33

Mode Of Inheritance

Supernumerary teeth are uncommon but have been well documented clinically. The majority of cases are isolated anterior teeth; examples of multiple or posterior supernumerary teeth are less common. This paper describes two examples of supernumerary teeth from archaeological contexts in Mesoamerica. The first case is of three individuals with supernumerary posterior teeth found in skull rows and pairs in a Postclassic Maya temple at the site of Ixlú in northern Guatemala. Two of these individuals exhibited bilateral supernumerary mandibular teeth. The second context is a Zapotec burial from the Jalieza site in Oaxaca, Mexico. This individual exhibited a single supernumerary tooth. The paper reviews supernumerary teeth with regard to frequency, ontogeny, and mode of inheritance and discusses the cases’ relevance for biological distance analyses.

Supernumerary teeth are considered as one of the dental anomalies where there is a development and/or training of a larger number of teeth. These may be isolated or associated with a syndrome, which can cause complications in the eruption, occlusion and a esthetics. Although the etiology of supernumerary is unknown, some authors make mention of theories as the dichotomy of tooth germ, hyperactivity of the dental lamina and genetic alterations, with matching patterns partnerships with autosomal dominant or autosomal recessive inheritance linked to X chromosome. Given the genetic importance in the development of supernumerary it is conceivable that in the case of sharing the same information, if a disturbance occurs in the dental formula, this should be repeated in his brothers. According to this view with a geneticist perspective this paper presents the situation of three triplets tricigoticos presenting alteration in a dental formula in terms interchangeably affected dentition (decidua and/or permanent) position on the bow (right or left) and impacted tooth. Key words: Dental anomalies, supernumerary, triplets.
