Bilateral Supernumerary Teeth Research Articles

Bilateral Supernumerary Teeth Presenting as Nasal Masses and Recurrent Rhinitis: An Interesting Case Report.

The presence of a tooth inside the nasal cavity is a rare clinical entity. The exact pathophysiology is not clear and most of the times, these patients present with non-specific symptoms. We encountered a 51-year-old male with symptoms of bilateral recurrent nasal obstruction and nasal discharge of 10 years' duration. Anterior rhinoscopy and diagnostic nasal endoscopy revealed a greyish white hard gritty mass covered with mucopurulent discharge in the floor of left nasal cavity and a mucosal covered bulge was noted in the floor of right nasal cavity. CT showed 2 hyperintense lesions in the maxilla reaching the floor of both nasal cavities. Diagnosis of supernumerary teeth was made and treated accordingly. Although the presence of tooth has been reported in ovaries, maxilla, maxillary sinus, mandibular condyle, mediastinum, this is the rare case reported with supernumerary teeth in both nasal cavities.

Supernumerary teeth in premolar and molar area on CBCT: a pictorial review.

Objective: to build a descriptive classification of premolar and molar supernumerary teeth (ST) when preparing the cone beam computed tomography (CBCT) report. The aim is also to share wide range of CBCT images in the open access publishing model. Material and methods: For our review we systematically searched for articles from PubMed with 1) free full texts on ST in molar and premolar area and using CBCT, and 2) articles providing with information on complications related with the presence of ST in molar and premolar area. We also added to our review studies providing with classic ST classifications in premolar and molar area. Results: We found 29 cases of ST, and we freely illustrated them with 84 figures. We separated our pictorial review in: 1) unilateral ST in the mandible, 2) unilateral ST in the maxilla, 3) unilateral undersized ST, 4) bilateral ST, 5) ST with additional features, and 6) cases with major hyperdontia. Conclusions: we build up the classification matrix for premolar and molar ST with 11 descriptors and 50 boxes. The descriptors were: 1) location if the ST crown in axial view, 2) vertical location of the cusp tip in relation with closest erupted tooth in coronal view, 3) shape, 4) distribution, 5) Position (in relation to normal tooth eruption) in sagittal view, 6) State of eruption of the ST in the sagittal view, 7) Follicle size measurement in sagittal view, 8) External root resorption of adjacent teeth by ST and its location in relation to the long axis of the involved tooth, 9) Internal resorption of ST, 10) Adjacent tooth complication, and 11) Damage to surrounding structures if ST removal. The open access figures from the literature illustrated 11 boxes. With our pictorial review we were able to illustrate 45 out of 50 boxes, and freely provide the readership with the most complete description of ST in premolar and molar area on CBCT than in previously published studies.

Multiple bilateral supernumerary teeth in a non-syndromic female patient - A case report with a comprehensive review

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.

A combination of kissing molars, maxillary bilateral supernumerary teeth and macrodontia: a rare case report

BackgroundSupernumerary teeth (ST) is defined as an additional number of teeth compared to the normal dental formula. The prevalence rate of ST varies from 0.5 to 3.8% in the permanent dentition. When ST located distal to the third molar is acclaimed as distomolar. Moreover, kissing molar is an extremely scarce condition of distomolars, pointed in the opposite direction in a single follicular space. Meanwhile, macrodontia is also a rare shape anomaly characterized by a large crown and tapering root.Case presentationA 22-year-old Chinese man presented a combination of kissing molars, maxillary bilateral supernumerary teeth and macrodontia. Radiographically, two maxillary bilateral distomolars located at the buccal side of adjacent third molars. One mandibular distomolar with the adjacent third molar was contacted by occlusal surfaces while roots were pointed oppositely, which could be diagnosed as KM. Furthermore, the left mandibular third molar can be inferred to be a macrodontia, characterized by a large crown and tapering root. After a thorough investigation, we excluded the possibilities of systemic diseases and genetic inheritance. However, the etiology of this rare combination deserves to be further explored.ConclusionThe combination of kissing molars, maxillary bilateral supernumerary teeth and macrodontia is very rare, especially presented in the patient with no syndromes. As there were no complications with these conditions, long-term observation has been recommended for the patient. In addition, the true etiology need a further exploration.

Anterior bilateral supernumerary teeth in primary dentition: a case report

Anterior bilateral supernumerary teeth in primary dentition: a case report

Dental development in children with supernumerary teeth in the anterior region of maxilla.

Development of human dentition has been used as a predictor for evaluating the growth and maturity of an individual. It is fairly identical in a specific population, but the effect of development on subjects with dental anomalies had not been fully explored, particularly on subjects with supernumerary teeth (ST). This study hence aims to evaluate the dental development of children with and without ST. Sample size calculation was conducted and 320 radiographs of subjects with and without supernumerary teeth (ST) were obtained from the archives of a teaching hospital. The subjects in both groups were age and sex matched. All the subjects belong to southern Chinese ethnicity aged 2 to 14years. The left-side dentition was scored, and dental age (DA) was estimated by obtaining scores from the southern Chinese dental reference dataset. Paired t test was used to calculate the difference between chronological age and dental age (CA-DA) for boys and girls with and without ST and further based on the number and position of ST. The difference between chronological age and dental age (CA-DA) was 0.10years for boys and 0.19years for girls with ST whilst 0.01 and 0.05years for boys and girls without ST (p > 0.05). The boys with bilateral ST showed significant delay in dental development of 0.23years (p < 0.05). Position of the ST did not have any influence on dental age. No significant difference was observed in the dental development of children with and without supernumerary teeth. Understanding dental development of children with supernumerary teeth may be useful in appropriate treatment planning of such conditions.

Non-syndrome patient with bilateral supernumerary teeth: Case report and 9-year follow-up

The presence of supernumerary teeth, also known as hyperdontia, is the condition of having teeth in addition to the regular number of teeth. The occurrence of multiple supernumerary teeth is often found in association with syndromes such as Gardner syndrome, Anderson-Fabry disease, Ellis-van Creveld syndrome, Ehlers-Danlos syndrome, incontinentia pigmenti, and Tricho-rhino-phalangeal syndrome. Only a few examples of nonsyndromic multiple supernumerary teeth have been reported in literature. In this report, we present the unusual case and 9-year follow up of a non-syndrome female patient with bilateral supernumerary teeth that occurred with an interval of several years.

両側下顎埋伏過剰歯の抜去後に同部位に新たな過剰歯が発生した1例

Supernumerary teeth are not rare, but metachronous supernumerary teeth in the same region are extremely rare. A 10-year-old boy with bilaterally impacted teeth in the mandible was referred to our hospital to undergo a detailed examination. A panoramic X-ray film showed three supernumerary teeth impacted bilaterally in the premolar region of the mandible. All of the supernumerary teeth were extracted, and the dental follicle around the supernumerary teeth was completely removed. However, about 2 years later, a panoramic X-ray film revealed four bilateral supernumerary teeth in the same region of the mandible. All of the supernumerary teeth were extracted. The extracted teeth were similar to normal permanent premolars and molars in both shape and size. A review of the past literature suggested that these supernumerary teeth might develop from the third dental laminae.

First report of bilateral supernumerary teeth associated with both primary and permanent maxillary canines

A very rare case of bilateral supernumerary teeth in the maxillary canine region and its management through a 3-step-conservative approach and 5-year-follow up is presented in this report. A 7-year-old Caucasian boy presented with 2 erupted supernumerary primary maxillary canines (53s and 63s) and two unerupted supernumerary permanent maxillary canines (13s and 23s). The treatment was carried out in three steps. In the first step, we removed teeth 53s and 63s. As the second step, early removal of teeth 53 and 63 and cementation of a space maintenance appliance (Nance's arch) were performed. In the third step, teeth 13s and 23s were removed, and the Nance's arch was maintained until the complete eruption of teeth 13 and 23. The management of this case with a proper treatment plan enabled us to solve the problem without complex procedures.

Multiple supernumerary teeth in the maxillary canine and mandibular premolar regions: a case in the postpermanent dentition

A supernumerary tooth is an extra tooth above the normal number, of which approximately 90% occur in the premaxillary region and show rudimentary forms of crown morphology. Most cases occur singly, with bilateral occurrence in the maxillary canine regions very rare in children with no other associated diseases or syndromes. A case of a 14-year-old boy with bilateral supernumerary teeth with normal crown shapes in both the maxillary canine and mandibular premolar regions. The supernumerary teeth in the maxilla were diagnosed at 12.2 years of age and in the mandible at 14.1 years of age. Four supernumerary teeth in the maxillary and mandibular canine-premolar region is a rare finding.
