With the rigidity of the root weakened by endodontic and restorative instrumentation (5,6), the sealing quality and tooth strengthening potential of endodontic replacement monoblocks become important issues.

The present report is a rare case where all the posterior permanent teeth had a single rooted morphologic presentation. Normal Root development depends on Morphodifferentiation and Hertwig’s epithelial root sheath (HERS).

Feb 28, 2020 · Most dental anomalies with respect to roots mainly involve single or supernumerary roots. Root anomalies can also be categorized as dilacerations, rizomegali, rizomicri, concrescence, hypercementosis and taurodontism. Single-rooted molars are described as conical, fused or pyramidal.

This review attempts to provide a broader meaning to the term monoblock and to see how this definition may be applied to the materials that have been used in the past and present for rehabilitation of the root canal space.

Oct 14, 2012 · The key stages of tooth development are described - the bud stage, cap stage, bell stage, and root formation stage. The roles of the enamel organ, dental papilla, dental sac, and Hertwig's epithelial root sheath in determining tooth shape and …

To develop a novel strategy for sealing and obturating dental root canals by tooth-like tissue regeneration, premolars with mature root apices were freshly collected, and root canals were prepared by following the clinical protocols in vitro.

Creation of a primary monoblock within the root canal either by an endodontic sealer or with an adhesive post-core system can reduce the stresses that occur inside the tooth structure. Keywords: endoREZ, finite element analysis, glass-fibre post, monoblock, MTA, polyethylene fibre post, post and core, Resilon, stress, tooth biomechanics.

We review the function of cellular structure/components such as Hertwig’s epithelial root sheath, cranial neural crest cells and stem cells residing in developing and adult teeth. We also highlight how complex signaling networks together with multiple transcription factors mediate tissue-tissue interactions that guide root development.

endodontically treated tooth roots and prevent root fracture in gutta-percha filled root canals 22. Till now , there are three bondable root filling materials available commercially. Of these, Resilon (Resilon Research LLC, Madison, CT) is the only bondable …
