UNLABELLED Extra teeth in dentition is termed as 'supernumerary teeth' and is a very well-known dental developmental anomaly. Supernumerary premolars are a rare anomaly in the maxillofacial complex. Its rarity and complex characteristics often makes it difficult to treat. Radiographs play an important role in assessment of both the location and the typing of supernumerary teeth. This article re...

Analysis of breeding records suggests that the occurrence of fused and supernumerary molars in the rice rat, associated with lower body weight than normal and with reduced fertility, is dependent on a single autosomal recessive gene subject to background modification. Molar fusion, which is preceded by stripping of the external enamel epithelium from the interdental lamina, may involve the firs...

Counts were made of the number of motoneurons innervating the hind limbs of 10-day normal and paralysed chick embryos whose right hind limb buds had been subjected to varying degrees of amputation prior to innervation. The number of motoneurons on the intact sides of the paralysed embryos was found to be similar to the number present in normal embryos prior to the major period of motoneuron dea...

AIM Supernumerary teeth represent a numerical dental anomaly in which more teeth than the norm are present in the dentition. A sixteen year sample of supernumerary teeth has been reviewed in order to analyse epidemiological data, morphological and topographic features of these teeth, especially of those located in the praemaxillary region. MATERIALS AND METHODS All cases in which supernumerar...

A case is presented of a nine-year-old male having a supernumerary maxillary right first primary molar together with a supernumerary maxillary right first premolar. The implications of early diagnosis and orthodontic management are discussed. The occurrence of supernumerary teeth in both the primary and permanent dentitions in the same patient seems to be rare. A review of the literature (inclu...

Aim: To present a report the case of a 10-year-old boy with a dentigerous cyst associated with inverted and fused supernumerary teeth in the anterior maxilla and to point out the relationship between supernumerary teeth and dentigerous cysts. Method: The supernumerary teeth were removed and the cyst was enucleated. Result: The patient has remained asymptomatic and experienced no recurrence duri...

Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition and more often seen in males. A s...

Supernumerary teeth or hyperdontia are defined as the teeth that exceeds the normal dental formula, regardless of their location and morphology. A supernumerary tooth is a developmental anomaly and it has been argued to arise from multiple aetiologies. Supernumerary teeth with orthodox shapes and sizes, that resemble the normal dentition are called 'supplemental teeth'. The supplemental teeth a...
