Defining properties of neural crest-derived progenitor cells from the apex of human developing tooth [PDF]
, 2008 The connective tissue of the human tooth arises from cells that are derived from the cranial neural crest and, thus, are termed as "ectomesenchymal cells." Here, cells being located in a pad-like tissue adjacent to the apex of the developing tooth, which

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control
Advanced Science, EarlyView.A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Endodontic Treatment with MTA in a Tooth with Open Apex-A Case Report [PDF]
Dental Journal of Advance Studies, 2013 AbstractThis case report describes the treatment of a tooth with necrotic pulp and open apex (maxillary left central incisor). In this conventional multiple-visit apexification with calcium hydroxide was replaced with a simple two step apical barrier techinique using MTA.
