Dens are crucial in the early development of many mammals, making den site selection an important component of parental care in such species. Resource availability and shelter from predators primarily govern den selection. Species inhabiting human-dominated landscapes typically den away from human disturbance, often shifting dens to avoid humans during the early life of their young. Domesticate...

Epithelial invagination is a morphological process in which flat cell sheets transform into three-dimensional structures through bending of the tissue. It is accompanied by apical constriction, in which the apical cell surface is reduced in relation to the basal cell surface. Although much is known about the intra-cellular molecular machinery driving apical constriction and epithelial invaginat...

Massive small intestinal into large bowel tumoral invagination

Dens in dente ve füzyon iyi bilinen ve iyi tanımlanmış dental anomaliler olmasına rağmen süpernumere dişlerde nadiren görülürler. Füzyon özellikle maksiller anterior dişlerde oluştuğunda estetik problem yaratır. Bu makalede, süpernumere iki anterior dişte nadir görünen dens in dente ve füzyonun birlikte görüldüğü bir olgu rapor edilmiştir. Although dens in dente and fusion are well-known and we...

Dens evaginatus is a rare dental anomaly characterized by the development of a tubercle on the occlusal surface of the tooth and can cause pulpitis, pulp necrosis, and periapical periodontitis due to tubercular fracture or attrition. Unlike with caries, pain caused by dens evaginatus may manifest itself in a distant location. Therefore, diagnosing the cause of that pain may prove problematic. D...

Congenital morphological dental alterations are related to the physiological phase of tooth development. Since the etiology of the dens invaginatus and supernumerary roots has yet to be fully determined, a rare presentation of dens invaginatus in a primary molar and a birooted deciduous maxillary canine were incidentally detected in routine radiographic examinations. Essential clinical consider...

In situ electrochemical extended X-ray absorption fine structure (EXAFS) was used to evaluate the structure of Pt dendrimer-encapsulated nanoparticles (DENs) during the oxygen reduction reaction (ORR). The DENs contained an average of just 225 atoms each. The results indicate that the Pt coordination number (CN) decreases when the electrode potential is moved to positive values. The results are...

Dens invaginatus is a developmental dental anomaly clinically characterized by a palatine furrow that can be limited to the coronal pulp or may extend to the radicular apex. The purpose of this paper was to present a clinical case of type III dens invaginatus, identified on the maxillary right central incisor in anterior periapical radiographs, in which the tooth was submitted to conventional e...
