It has been established that human dental pulp and periodontal ligament contain a population of mesenchymal stem cells (MSCs). However, the phenotypic analysis in terms of putative stem cell markers expressed by these stem cell populations is incomplete. It is relevant to understand whether stem cells derived from closely related tissues are programmed differently. This book therefore, provides an insight into the phenotypes of dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PDLSCs). Both the stem cells express embryonic stem (ES) cell markers. Differences were observed in...

Shade selection and shade matching of a restoration is the critical final step in aesthetic restorative dentistry once morphology and occlusion are addressed. Color is governed by visual and scientific components and in dentistry it is communicated on a regular basis but often misunderstood, since every human eye is not capable of perceiving it in a standardized manner. Achieving a predictable aesthetic restorative outcome not only involves the dentists mastery of the art of perceiving color and adequately communicating it, but also, a proper interpretation of this information by the...

A new generation of imaging devices have evolved since the advent of X-rays. The simple X-ray devices are giving way to digital systems in which computer screens replace film. In contrast, the impact of radiographic imaging on the management of the periodontal patient has essentially remained unchanged for decades. This does not imply that the imaging needs in periodontology are met or there is little room to improve patient outcomes by using better imaging methods. New technologies have emerged to address the critical needs in periodontal diagnosis. This book attempts to examine the...
