A discriminant analysis was performed in a sample of 303 children with developmental disorders (DD) and 303 healthy controls (C) in order to test whether some oro-dental and physical minor anomalies could discriminate these groups of children. DD sample comprised 176 mentally retarded (MR) children. 70 children with impaired hearing (IH) and 57 children with impaired vision (IV). The control gr...

Diverse morphological tooth deformities are found in various shapes, textures, and prevalence. They can be sporadic or syndromes, nutritional, environmental, genetic, and ethnic related. Most of these tooth-born (ie, patient born with the deformation) deformations (eg, shovel-shaped incisors, tuberculum Carabelli, variations in number and shape of cusps, dens invaginatus, taurodontism) have bee...

Dens invaginatus is a relatively common dental malformation resulting from an infolding of enamel organ into the dental papilla varying in depth into the tooth tissues. Complex morphological anatomy associated with the pulpal pathology presents inaccessibility to completely remove the necrotic pulp tissues and hence poses challenges in rendering endodontic treatment. A combination of nonsurgica...

Talon cusp (TC) and dens invaginatus (DI) are relatively rare developmental anomalies which affect the shape of teeth. TC is an additional cusp that projects predominately from the lingual surface of anterior teeth. DI is a deep surface invagination of the crown or root which is commonly detected on routine radiographic examination. Both of these anomalies are observed more frequently in perman...

The aim of this paper is to describe a unique and unusual case of concomitant appearance of morphological dental anomalies in the maxillary anterior region, along with its management in a patient with no systemic abnormality. This case report describes the clinical and radiographic features of talon cusp, dens invaginatus, shovel-shaped incisors and a supernumerary tooth occurring in a single p...

AIM To describe the successful non-surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals. SUMMARY Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The di...
