Pulp Capping

The emergence of Mineral Trioxide Aggregate (MTA) as endodontic repair filling material has generated a lot of interest due to its superior sealing ability and biocompatibility. Although MTA possesses superior sealing ability to traditional endodontic repair filling materials, such as calcium hydroxide, but it has poor handling characteristics. A novel endodontic repair filling materials with similar chemical composition, but improved handling characteristics, was recently developed. Recently, BioAggregate repair filling materials is claimed as biocompatible material and promotes cementogenesis and forms a hermetic seal inside the root canal. More recently, Biodentine and EndoSequence endodontic repair materials introduced to the market. Both materials have recommended for perforation repair, apical surgery, apical plug, and pulp capping. This article focused about physical properties of endodontic repair filling materials. - See more at: http://www.sciencedomain.org/abstract.php?iid=461&id=12&aid=3984#.U2X0_HZTV14

Abstract –  The talon cusp is a relatively uncommon dental anomaly manifested as an accessory cusp-like structure on the crown of anterior teeth. The presence of a talon cusp can cause clinical problems. This article reports the case of a patient presenting a talon cusp affecting the permanent maxillary right central incisor causing clinical problems related to caries, displacement of the tooth, occlusal position and tendency to dental traumatism. The management of this tooth included caries removal and reduction of the cusp. Pulp-capping with calcium hydroxide was required because of the presence of pulp horn extensions in the talon cusp.

International Endodontic Journal, 45, 689–701, 2012.AbstractThe recent isolation and characterization of mesenchymal stem cells (MSCs) in dental tissues constitutes a major step forward in the development of new treatment strategies. MSCs are essential for dental pulp repair and the success of regenerative endodontic procedures. It is important to understand that immune cells and cytokines can affect stem cell function, which can impact their healing potential. On the other hand, stem cells are immunoprivileged and have the ability to modulate immune and inflammatory responses, which can be utilized to improve treatments outcome. This review addresses both aspects of this interaction and suggests that any change on both sides can tip the balance in favour of either persistence of inflammation or healing. Finally, the therapeutic relevance of the interaction between MSCs and immune system relative to current treatments is discussed, and future research and treatment perspectives are suggested.The recent isolation and characterization of mesenchymal stem cells (MSCs) in dental tissues constitutes a major step forward in the development of new treatment strategies.
