OBJECTIVES The purpose of this study was to evaluate the clinical and radiographical characteristics of non-syndromic hypodontia and hyperdontia in the permanent dentition. STUDY DESIGN This study included 139 patients. Clinical and radiographical examinations were carried out by two examiners. Number and localization of missing or supernumerary teeth, and pathologies associated with the teet...

Introduction. Hyperdontia is an odontostomatologic anomaly characterized by an excess in tooth number. It seems to occur more often in patients with hereditary factors concerning this anomaly: this case represents a rare form of hyperdontia, with bilateral multiple supernumerary teeth, with evident penetrance of the phenotype in the family unit engaged in the present study. The karyotype determ...

Dental anomalies of tooth number influencing the development of permanent dentition are quite common, and more numeorus than in the case of primary dentition, however, combined occurrence of hypodontia and hyperdontia is a rare phenomenon, especially in the same dental arch. The purpose of the present report is to describe a case of concomitant hypo-hyperdontia (CHH) in an 8 year-old male with ...

Hyperdontia presents as an odontostomatologic derangement where and excess in tooth number is observed. Mesiodens the premaxilla is most commonly occurring supernumerary tooth. It usually clinical form. The following case reported with erupted consequences and management has been discussed elaborate details. Keywords: Mesiodens, Supernumerary tooth, Cephalometrics, Preadjusted edgewise.

Prevalence of anomalies of deciduous teeth has been analyzed in the general population of Zagreb preschool children. The sample comprised 2,987 children from 3 to 6 years of age (1,582 boys and 1,405 girls). Hypodontia was found in 0.47%, hyperdontia in 0.10%, and double teeth in 0.43% of total sample. Total prevalence of all anomalies in the sample was 1.0%. The sample for the analysis of perm...

Nonsyndromic familial hyperdontia/supernumerary teeth is a rare disorder of odontogenesis characterized by an excess number of teeth with familial background. They can be supplemental (resembling natural teeth), conical, tuberculate or molariform. Early clinical and radiographic examination of the supernumerary teeth allow for optimal yet minimal treatment. This article reports two rare cases o...
