Compared with cold lateral condensation and continuous wave of condensation which are classically used in clinical, newly emerging single-cone obturation technique is easy-to-operate as well as time-saving. Especially when combined with bioceramic root canal sealers of improved physicochemical and biological properties, single-cone obturation technique showed satisfactory short-term outcomes in clinical observations. However, difficulties still exist in avoiding the root canal overfilling and in operating the retreatment. Besides, the long-term effects of single-cone obturation with bioceramic sealers still remain unclear. This article makes an overview on the history and development of single-cone obturation ,and provides analysis of its pros and corns. Furthermore, we would also like to summarize its clinical application and look into its future improvements.

Pulp and periapical diseases are common and frequently occurring diseases of which diagnosis and treatment must be dealt with by the dental clinicians. The diagnostic techniques of these diseases include evaluation of pulp vitality, measurement of pulp blood circulation and analysis and judgment of root canal anatomy. With the continuous emergence of digital and imaging technologies, the correct application of these technologies in clinic will help clinicians improve their abilities in diagnosis and treatment of related diseases. The present article summarizes and reviews the progress of assistant technology for diagnosing dental pulp and periapical diseases in recent years and puts forward some suggestions for its application.

OBJECTIVETo discuss orthodontic extrusion of crown-root fractured teeth before restoration.

METHODS3 cases with fractured teeth and 2 cases with root caries were performed canal therapy.

RESULTSOrthodontic extrusion of the root was carried out before restoration. All cases were satisfactory after treatment.

CONCLUSIONSOrthodontic extrusion of remaining root before restoration not only can maintain the remaining root but also obtain functional and esthetic results.

OBJECTIVETo investigate the associated factors that influence the removal of intraradicular resinifying material.

METHODSOne hundred and ninety-seven root canals were treated with resinifying therapy, then the canals were negotiated with sonic, ultrasonic and hand instrument. Those failed to be negotiated were splinted longitudinally and observed with ZOOM-630E stereomicroscope.

RESULTSSonic and ultrasonic instrument negotiated more canals, especially those with jelly-like resinifying material (76.0% approximately 84.0%) and of smaller curvature (90.0% approximately 100.0%) or larger initial apical file (IAF) size (93.8% approximately 100.0%). Those with hard resinifying material and of bigger curvature or smaller IAF size were hard to be negotiated no matter which kind of instrument was used (0 approximately 20%).

CONCLUSIONSVibratory instrument can effectively removal intraradicular resinifying material.

Root canal therapy is currently the most effective treatment for pulpal and periapical diseases. With the innovation of endodontic theory and techniques, the concept of contemporary root canal therapy has been established and promoted gradually. Advances in endodontic technology, instruments, and materials have increased the safety and clinical success rate of root canal therapy. This article reviews the recent theoretical research and clinical practices of contemporary root canal therapy.
