Oligodontia is the agenesis of 6 or more teeth, excluding third molars. The etiology of congenital absence of teeth is believed to be rooted in heredity or developmental anomalies. The absence of teeth in patients can cause aesthetic, functional, and psychological problems, particularly if the anterior region is involved. This case report describes the multidisciplinary treatment approach towar...

Double or fusion of the teeth is a primary developmental anomaly union of two independently developing primary or permanent teeth. The tooth fusion may contribute to various significant problems such as crowding, caries and periodontal diseases and they may be associated with anomalies in the succeeding permanent dentition which necessitate careful examination & proper treatment planning becaus...

Objectives To present the treatment approach for restoration of localised anterior erosive wear using a combination dental materials. Clinical considerations A patient presented in private practice concerned about aesthetics his teeth. The patient's history and clinical examination revealed on labial palatal aspects maxillary central incisors right lateral incisor. formulated plan was to restor...

An unusual case of fusion combined with concrescence of a supernumerary tooth and a central incisor is presented. In order to prevent a deep periodontal pocket following the separation, a twostep technique was attempted. The first stage consisted of surgical exposure of the roots and separation with closure to allow in-growth of connective tissue. Four weeks later, the fused crowns were separat...

Tyrannosaurid theropods display several unusual adaptations of the skulls and teeth. Their nasals are fused and vaulted, suggesting that these elements braced the cranium against high feeding forces. Exceptionally high strengths of maxillary teeth in Tyrannosaurus rex indicate that it could exert relatively greater feeding forces than other tyrannosaurids. Areas and second moments of area of th...

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...

Inverted mesiodens is a disorder of Odontogenesis relatively characterized by an excess number of teeth in the premaxillary region, in between the central incisors and in an inverted direction. The etiology of inverted mesiodens is still unknown. The complications associated with inverted mesiodens include eruption disturbance of adjacent teeth, displacement & rotation of the central incisors, ...

The evolutionary success of mammals is rooted in their high metabolic rate. A high metabolic rate is sustainable thanks to efficient food processing and that in turn is facilitated by precise occlusion of the teeth and the acquisition of rhythmic mastication. These major evolutionary innovations characterize most members of the Class Mammalia. Cetaceans are one of the few groups of mammals in w...
