Retrospective analysis of factors influencing the eruption of delayed permanent incisors after supernumerary tooth removal.
AIM: This was to assess the predictability of eruption of delayed permanent incisors after supernumerary removal and creation of adequate space, in relation to: root maturity, degree of vertical impaction, and degree of angulation of impaction. METHODS: The dental records of children with supernumerary teeth delaying the eruption of permanent incisors were analysed. The type of a supernumerary tooth, its location and position were recorded, along with the stage of root maturation, angulation and vertical distance of impaction of the permanent incisor. At the initial surgery, the unerupted supernumerary tooth and any retained primary incisors were removed. The unerupted permanent incisor was not exposed. If necessary, the maxillary primary canines were removed to create sufficient space for eruption of the delayed permanent tooth. A secondary surgical procedure was planned after 18 months if there was no significant progress of the permanent tooth towards eruption. STATISTICS: All data were entered onto a Microsoft Excel spread sheet and analysed using Fisher's Exact Tests throughout due to the small numbers. RESULTS: Sixty-six supernumerary teeth were removed, 22 from boys and 44 from girls with ages ranging from 6 to 10 years 6 months at the time of surgery. Primary canines were extracted in 59.1% of cases. Spontaneous eruption occurred in 89.4% of delayed permanent teeth. The mean time to eruption was 9.2 months (median = 7 months). There was no statistically significant association between tooth eruption and root maturity or the degree of vertical impaction. There was an association between eruption and the degree of the angle of impaction of the permanent incisor (p<0.05). CONCLUSION: The majority of delayed permanent teeth erupt spontaneously if sufficient space is available or created at the time of removal of the unerupted supernumerary. The angulation of impaction of the permanent incisor is associated with a delay in eruption.

[Anatomical studies on a supernumerary tooth considered to be a successional tooth of the lower first molar].
The purpose of this study is to investigate features of the successional tooth of the lower first molar. Materials investigated in this study deal with a supernumerary tooth formed at the distolingual deep part to the lower right first molar of a male patient aged twenty-four. It was observed with binocular microscopy and under X-ray. The occlusal surface of it was observed with scanning electron microscopy. Horizontal ground sections of it were prepared and observed with polarizing microscopy, fluorescent microscopy, and scanning electron microscopy. It is thought that this supernumerary tooth is a true successional tooth of the lower first molar because it was formed at the distolingual deep part to the lower first molar and the fissure of it is Y-shaped and it has five cusps. It is considered that two impressions at buccal and distal surfaces of it isn't original hereditary features but was accidentally formed by pressures of mesial and distal roots of the lower first molar. The rough form of it has most resemblance to the lower second premolar and distal and lingual parts of it are smaller than that of the lower first molar. But fundamental features of the lower first molar are preserved in it. It is thought that the center of the molarization field of human lower successional teeth lies at the successional tooth of the lower first molar because the form of the occlusal surface of it is more complex and functional than those of the lower first and second premolars.

A maxillary central incisor having two root canals geminated with a supernumerary tooth.
This article reports the treatment of a maxillary left central incisor geminated with a supernumerary tooth. A patient having labial swelling around the maxillary incisors was referred to this hospital for diagnosis and endodontic treatment of the maxillary left central incisor. Clinical and radiographic examinations revealed a tooth having two roots and three canals. Examination of a rubber base impression of the cleaned canals showed there was neither perforation of, nor communication with, the radicular groove in the tooth.

A supernumerary tooth in a 1.7 million-year-old Australopithecus robustus from Swartkrans, South Africa.
The maxillary dental arch of a partial cranium of an adult specimen of Australopithecus robustus shows the presence of a supernumerary tooth between the right first and second incisors. The fossil specimen, SK 83, is from Swartkrans Member 1 sediments, considered, on the basis of associated fauna, to be approximately 1.7 million yr old. The specimen was analyzed macroscopically, stereomacroscopically and by X-ray computed tomography. The anatomic position and the morphology of the tooth are consistent with a diagnosis of supernumerary lateral incisor rather than a mesiodens or a retained deciduous tooth. This is the first description of a supernumerary tooth found in Plio-Pleistocene hominid fossils from South African cave deposits.

Misdiagnosis of an impacted supernumerary tooth from a panographic radiograph.
A panographic radiograph of a 31-year-old man revealed the presence of an impacted supernumerary paramolar. Periapical radiographs of the same area failed to confirm the existence of this supernumerary tooth. A review of the inherent distortion factors present in panographic radiography leading to the misdiagnosis is discussed.

The treatment of a fusion between the maxillary central incisor and supernumerary tooth: report of a case.
Fusion has been described as a developmental anomaly characterized by the union of two adjacent teeth. Supernumerary teeth develop as a consequence of the proliferation of epithelial cells from dental lamina. In this paper a fusion between maxillary central incisor and a supernumerary tooth which required endodontic, surgical and periodontal treatment is presented.

Multiple dens invaginatus affecting maxillary lateral incisors and a supernumerary tooth.
Dens invaginatus is a developmental variation resulting from an alteration in the normal growth pattern of the dental papilla of a tooth. This anomaly occurs predominantly in maxillary permanent lateral incisors. Multiple occurrence in maxillary incisor teeth in the same patient has frequently been reported, and examination of bilateral teeth for the anomaly is often carried out routinely. This paper reports an unusual case of multiple invaginations, including dens invaginatus affecting maxillary lateral incisors and a supernumerary tooth and minor invaginations of the upper canines. Moreover, the case illustrates the importance of examining all the teeth in patients who present with dens invaginatus and palatal pits in incisors and canines. The possibility that the supernumerary tooth had resulted from gemination of the lateral incisor tooth germ is discussed.

A supernumerary tooth fused to the distal surface of a mandibular third molar.
Fusion is a tooth anomaly considered to be the result of the union between two adjacent tooth buds. The incidence of fusion is less than 1 percent of the population. The following is a case report of a unique form of a supernumerary tooth fused to the distal surface of a mandibular third molar. Radiographic evaluation demonstrates the communication of the pupal tissues. A differential diagnosis of developmental anomalies is discussed.

Endodontic management of a fused maxillary lateral incisor with a supernumerary tooth: a case report.
Fusion is a rare occurrence and its definitive diagnosis is of prime importance for successful root canal treatment. This case report discusses the endodontic and esthetic management of fused maxillary lateral incisor with a supernumerary tooth that presented with spacing between the fused tooth and the adjacent central incisor. Nonsurgical endodontic treatment was performed on the fused teeth followed by postendodontic esthetic restoration. The patient remained symptom-free and there was a reduction in the size of periapical radiolucency after 1 year.
