successful endodontic treatment requires thorough knowledge regarding each root canal system of any tooth and probability of extra canals should be considered. second maxillary molar with two palatal root canals is not frequent and its incidence reported in literatures is about 0.4–2%. the present case report describes non-surgical retreatment of maxillary second molar with two palatal root can...

Humans love the taste of sugar and the word "sweet" is used to describe not only this basic taste quality but also something that is desirable or pleasurable, e.g., la dolce vita. Although sugar or sweetened foods are generally among the most preferred choices, not everyone likes sugar, especially at high concentrations. The focus of my group's research is to understand why some people have a s...

Mammalian tooth development relies heavily on the reciprocal and sequential interactions between cranial neural crest-derived mesenchymal cells and stomadial epithelium. During mouse tooth development, odontogenic potential, that is, the capability to direct an adjacent tissue to form a tooth, resides in dental epithelium initially, and shifts subsequently to dental mesenchyme. Recent studies h...

A method of measuring the volume of the human dental pulp cavity is described. The crown of an extracted tooth is divided from its root. .After cleaning the pulp cavity, it is filled with an elastomer, and the fractured tooth surfaces repositioned before the elastomer sets. The tooth is corroded in acid to release the elastomer which is then weighed, and its volume calculated. The method has be...

objective: tooth loss is a common problem and since current tooth replacement methods cannot counter balance with biological tooth structures, regenerating natural tooth structures has become an ideal goal. a challenging problem in tooth regeneration is to find a proper clinically feasible cell to seed.this study was designed to investigate the odontogenic potential of human bone marrow mesench...
