This study investigates the anatomic structure at the origin of pulmonary supernumerary arteries and their parent conventional artery. Histological examination showed that at the origin of each supernumerary artery the wall of the parent conventional artery is organized into a distinct V-shaped structure, which begins on the hilum side of each supernumerary artery as a funnel-shaped channel run...

An apparently healthy 12-year-old boy was referred to the Department of Oral and Maxillofacial Pathology whose chief complaint was the presence of an additional tooth in the upper front teeth region. His medical, dental and family history was not relevant. Intraoral examination revealed an erupted, supernumerary tooth palatal to permanent maxillary right central incisor and radiograph revealed ...

Supernumerary teeth are additional teeth besides the normal series and can be found in any region of the dental arch. Supernumerary teeth can be classified according to their form and locations. Early diagnosis and treatment of patients with supernumerary teeth may prevent or minimize complications. The treatment options depend on the type and position of the supernumerary tooth and its effect ...

Supernumerary teeth are teeth in excess of the normal series occurring in any region of the dental arch. They are located mostly in the anterior maxillary region and are classified according to their location and morphology. The tuberculate type of supernumerary tooth possesses more than one cusp or tubercle (barrel shaped). It is rare to find bilateral tuberculate supernumerary teeth in the pr...

AIM The aim of this article is to report a case of bilateral multiple impacted supernumerary teeth. A discussion of possible mechanisms of development is also presented along with a concise review of the literature. BACKGROUND Supernumerary teeth occur in the context of various scenarios in the primary and the permanent dentition. Multiple supernumerary teeth are a rare finding especially in ...

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...

Supernumerary teeth are common in general population and occur frequently in patients with familial trait. However, it is rare to find supernumeraries in individuals with no associated disease or syndrome. Supernumerary teeth are found in any region of maxilla and mandible, with a predisposition for anterior maxilla. A case of endodontically involved supernumerary lateral incisor is described.

Fusion is a developmental anomaly, which is rarely observed in clinic. It can happen between normal and supernumerary teeth. Supernumerary teeth are those that exceed the normal dental formula. In this paper we report a rare case of fusion, involving permanent maxillary second molar and a supernumerary tooth, where endodontic treatment was provided and final restoration was accomplished.

Purpose The purpose of this study was to investigate the impacted supernumerary teeth which were initially detected on panoramic radiographs by using cone beam computed tomography (CBCT). Materials and Methods In this retrospective study, supernumerary teeth diagnosed on panoramic radiographs taken from patients who had admitted for routine dental treatment were evaluated using CBCT. Patients...

Introduction Supernumerary teeth may be defined as extra teeth occurring within the dental arch. These teeth may be found within the deciduous dentition, but are more commonly found within the permanent dentition. The prevalence of supernumerary teeth in the permanent dentition has been investigated in several studies (Table 1); it varies from 0.45% to 4.5%. In Ireland the levels vary between 2...
