Previous studies have suggested that Bmp4 is a key Msx1-dependent mesenchymal odontogenic signal for driving tooth morphogenesis through the bud-to-cap transition. Whereas all tooth germs were arrested at the bud stage in Msx1(-/-) mice, we show that depleting functional Bmp4 mRNAs in the tooth mesenchyme, through neural crest-specific gene inactivation in Bmp4(f/f);Wnt1Cre mice, caused mandibu...

An ectopic tooth is an eruption of a into abnormal location, such as the palate, sinonasal cavities, mandibular condyle, coronoid process, orbit, or skin. It can be found incidentally presented with variety symptoms, unilateral nasal obstruction, epistaxis, rhinorrhea, chronic congestion, headache, facial pain. Ectopic teeth are most commonly supernumerary, but may also deciduous permanent teet...

Introduction: Nasal teeth eruption is a rare phenomenon. The variability of symptoms and generic history makes the diagnosis difficult. This difficulty is more challenging when the tooth is placed in the depth of septum.   Case Report: Our case is an example of this problem. Herein, we present a case of intraseptal tooth with nasal obstruction and septal deviation and recurrent sinusitis. We p...

OBJECTIVES Dental impaction is a very frequent problem. Supernumerary teeth, or hyperdontia, are the presence of additional teeth to the normal series in the either of the dentition. The presence of impacted and/or supernumerary teeth can cause various complications. The objective of the present study was to determine the prevalence of impacted and supernumerary teeth in the North Indian popula...

Practitioners are frequently faced with tooth eruption anomalies during the gradual emergence of complete adult dentition, and notably disorders related to tooth impaction (Hurme et al. 1949). This process, which affects deciduous, permanent and supernumerary teeth, is thought, apart from more general causes, to stem from a breakdown in the dynamics of eruption as a result of numerous different...

Autotransplantation is a viable treatment option to restore esthetics and function impaired by abnormally shaped teeth when a suitable donors tooth is available. This paper describes the autotransplantation and 2-year follow-up of a supernumerary maxillary incisor as a replacement to a misaligned maxillary incisor with abnormal crown morphology and size. The supernumerary incisor was immediatel...

Pediatric dentistry is not only about the hard (Teeth) and soft tissues which are visible can be treated. There so many dental anomalies seen through naked eyes inspite of them being in oral cavity unnoticed i.e, root. These detected while patient undergo treatment for culprit tooth these present adjacent to or undergoes radiographic examination diagnosis. During diagnosis primary molar radiogr...

Supernumerary teeth may be encountered as an incidental finding on a radiograph. When impacted, they associated with clinical signs related to different problems such failure of eruption, displacement, root resorption or cystic lesions. They occur in primary and permanent dentition, both the maxilla mandible can single multiple patients syndromes. Mesiodens is most commonly impacted tooth appea...

Ellis-van Creveld (EVC) syndrome is an autosomal recessive chondrodysplasia. The affected individuals bear a series of skeleton defects, congenital heart septum anomalies, midfacial and dental defects. Previous studies using Evc or Evc2 mutant mice have characterized the pathological mechanism leading to various types Some patients with EVC supernumerary tooth; however, it not known yet if ther...

Fusion of teeth is the union of two or more tooth germs, which are usually separated. Depending upon the stage of odontogenesis, it can be complete or incomplete. The present case describes fusion between the maxillary primary right central and lateral incisor with a supernumerary tooth. Clinical and radiographic examination revealed the presence of fused triple teeth. The fused teeth were extr...
