Transient apical breakdown of a discoloured maxillary central incisor during orthodontic treatment: A case report.

Transient apical breakdown (TAB) appears to be a repair process taking place in the pulp and periapical area of traumatised teeth which may display crown discoloration and have no responses to pulp sensitivity tests. Few TAB cases induced by orthodontic forces have been reported so far. Presented is a case report in which TAB occurred on the maxillary right central incisor during orthodontic treatment.

Effect of Post Placement on the Restoration of Endodontically Treated Teeth: A Systematic Review.

Purpose: The aim of this study was to assess the effect of root canal post placement on the restoration of endodontically treated teeth.

Materials And Methods: PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and two Chinese databases (China National Knowledge Internet and the Wan-fang database) were searched to identify randomized or quasi-randomized clinical trials related to post-and-core systems for the restoration of endodontically treated teeth. Studies published prior to August 2013, performed on humans, and written in English or Chinese were considered for inclusion.
