abstract：:Aspirating the unknown contents of a bony cavity and saline irrigation of a body wound are both basic surgical techniques. These two techniques have been combined in treating persistent periradicular pathosis in two cases. The cases demonstrate significant bony healing of extensive periradicular defects after the use ...

abstract：:It is known that many factors participate in the process of inflammation and pain transmission. Recently, various neuropeptides have been demonstrated in the intrapulpal nerve fibers immunobiohistochemically. These neuropeptides may play some role in the process of inflammation and transmission of pain sensation. In t...

abstract：:Removing posts from root canals prior to endodontic retreatment is often a challenge. The Gonon post removing system (Thomas Extracteur De Pivots; FFDM-Pneumat, Bourges, France) is safe and efficient and can be used for anterior, bicuspid, and even molar teeth. The Gonon system is illustrated with one clinical case. ...
