Supernumerary tooth is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. They can cause a variety of complications in the develo-ping dentition. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anteri...

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 follow...

The single replacement from milk teeth to permanent teeth makes mammalian teeth different from teeth of most nonmammalian vertebrates and other epithelial organs such as hair and feathers, whose continuous replacement has been linked to Wnt signaling. Here we show that mouse tooth buds expressing stabilized beta-catenin in epithelium give rise to dozens of teeth. The molar crowns, however, are ...

Supernumerary roots consist of a developmental disturbance which can occur to any teeth, and knowledge about its occurrence is particularly important for the conduction of surgical or endodontic treatment of the affected tooth. In view of this reality, an attempt was made to determine the prevalence of supernumerary roots in lower premolars. The study was carried out with 200 periapical radiogr...

Fusion is an anomaly manifested in both deciduous and permanent dentitions. Fusion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. Triple tooth refers to the union of three separate tooth entities. It can occur by fusion, germination, con...

A case history of on anomoly of the dentition, a supernumerary fused to a central incisor, is presented. The treatment of the anomoly is described. The treatment involved many of the various disciplines of dentistry in order to retain the tooth, and achieve a good functional and esthetic result.

Mesiodens, a common supernumerary tooth found in the midline inanterior maxilla. Multiple mesiodens are termed as ‘mesiodentes’. This report presents an extremely rare occurrence of two mesiodentes with different morphologyand their associated problems. It is an asymptomatic condition and is usually diagnosed on routine clinical and radiographic examination.Thisarticle also elucidate about the ...
