Malformations of the tooth root in humans [PDF]
Frontiers in Physiology, 2015 The most common root malformations in humans arise from either developmental disorders of the root alone or disorders of radicular development as part of a general tooth dysplasia. The aim of this review is to relate the characteristics of these root malformations to potentially disrupted processes involved in radicular morphogenesis.

Posts and the root-filled tooth [PDF]
British Dental Journal, 2005 It is clear that teeth often require significant reconstruction following root canal treatment. It is also evident that there is an enormous variety of ways that can be used to achieve this. Although there is some debate about the relative contributions of the root filling and coronal restoration to endodontic success, it is agreed that the best ...
