Appropriate Treatment

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.

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

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.

Deciduous Molar

One of the most common dental anomalies encountered by the pediatric dentist is the congenital absence of second premolars. Once diagnosed, the appropriate treatment necessitates the formulation of a comprehensive treatment plan, which is dependent upon a number of factors. Considerations include: the condition of the deciduous molar, dental and skeletal relationships, dental age of the patient, willingness of the patient to undergo extensive dental treatment and financial considerations. Approaches to the management of congenitally missing premolars have been described in the literature, including the more recently available option of dental implant placement. The objective of this paper is to present a review of the literature with emphasis on the considerations needed for appropriate treatment planning when the practitioner is confronted with this diagnostic challenge.

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.

Supernumerary tooth (ST) are the developmental disorders that could be found in either of the dental arches. Whereas the single ST is quite a common entity, multiple ST are rare, especially when they are not related to any syndromes or disorders. The experience of observing one such case is reported in light of a review of the literature on this condition. This report describes  a case of a non-syndromic 22-year-old female who presented with multiple erupted and impacted ST in the mandibular premolar region. The patient was educated about the complications and consequences associated with ST and was advised for extraction of erupted supernumerary premolars and observation of the impacted ones but the patient denied any treating as ST were not causing any immediate problem. Radiographic assessment plays a pivotal part in early diagnosis and intervention as it aids in avoiding complications associated with ST, especially in non-syndromic cases or when they are asymptomatic. Patients should be counselled regarding the same with proper explanations of all the treatment options.

Background. Supernumerary tooth is defined as any extra tooth or odontogenic structure that is formed on normal dentition. Supernumerary teeth cause such problems as deficiency in tooth growth, ectopic growth, displacement, crowding, diastema, odontogenic cyst formation, decay of the adjacent tooth, malocclusion, and esthetic problems. This study was conducted aiming at determining epidemiology of supernumerary teeth in Ardabil city in 2020. Materials & Methods. In this retrospective descriptive analytical study, 5000 panoramic radiographs of patients referring to Rad and Baser Oral and Maxillofacial Radiology Centers were selected through multistage sampling method during 2015–2020. The data were collected by checklist and analyzed with using SPSS-21 and chi-squared, Fisher, and one-way ANOVA tests with a significance level less than 5%. Results. The prevalence of supernumerary teeth was estimated as 1.06% (n = 53), and no significant difference between the males and females was seen. Most supernumerary teeth were found in the distomolar (44.1%) and parapremolar (29.4%) locations. The majority of supernumerary teeth were present in the maxilla (73.5%) and were impacted (77.9%) and unilateral (71.7%). The number of supernumerary teeth was 68 cases and majority of patients (86.8%) had one supernumerary tooth. Conclusion. Supernumerary tooth in this study had a high prevalence compared to similar studies, and unlike most previous studies, the most common type of supernumerary tooth was distomolar. Early diagnosis and proper medical planning are essential for managing supernumerary teeth.

Delayed Eruption

Mesiodens is the most common supernumerary tooth and is present in the midline between the two central incisors. It occurs mostly due to hyperactivity of the dental lamina. They are usually small, with a cone shaped crown and a short root, may be single or paired, erupted or impacted and occasionally even be inverted. Presence of more than one mesiodens is termed as mesiodentes. Presence of mesiodens may cause impaction or delayed eruption of permanent teeth, malocclusion leading to disturbance in chewing, swallowing and speech, root resorption of the adjacent teeth, impaired dentofacial aesthetics, and sometimes cyst formation. The erupted mesiodens can be easily diagnosed clinically, and the unerupted ones are best diagnosed by clinical and radiological evaluation. Although mesiodens is the most common supernumerary teeth, presence of double mesiodens is uncommon. In this paper we describe a case of palatally erupted double mesiodens and its management in a 20year old girl.

ABSTRACT Mesiodens is the term used for describing the supernumerary tooth that occurs in the maxilla, between the central incisors, in the midline region. These may erupt in the oral cavity or keep themselves impacted. Their presence causes cleaning inadequate, impossibility or difficult of the eruption of the regular teeth and having the aesthetic compromised. This paper aims at showing that early identification of supernumerary teeth, planning and correct approach, allow the preservation of the teeth and adjacent structures. This article presents the clinical case of a seven-year-old child, male, who sought for treatment complaining that teeth 11 didn't appear in the buccal cavity. Clinical and radiographic exams were done and they demonstrated the presence of the supernumerary tooth. The plan of treatment aimed at the correct localization, extraction of this supernumerary tooth and continuous follow up of the case.

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.
