Intentional replantation for the retreatment of mandibular second molar: a case report.

When the use of root canal retreatment and apical surgery experiences difficulty in treating endodontic diseases, intentional replantation is an optional clinical technique used to retain the tooth. A 28-year-old female complained of chewing discomfort at the mandibular second molar after undergoing root canal treatment 3 month ago. History record and radiographic examination revealed that a C-shaped root canal system was filled with gutta-percha in the mandibular second molar.

[Repair of root fracture in maxillary second premolar with MTA: a case report].

MTA is rarely applied in the repair of root fractured section. A case of maxillary second premolar which fractured ten years ago had been connected with MTA in this article and the cone beam CT was used to evaluate the treatment effect.

[Meta analysis of association between TNF-α-308 polymorphism and periodontitis in Chinese Han population].

Purpose: To assess the association between TNF-α-308 polymorphism and periodontitis in Chinese Han population.

Methods: Articles published between 1994 and 2011 were searched in the fulltext database of CNKI, Chinese Biomedical Literature Database, Wanfang Database and PubMed. Case-control studies on TNF-α-308 polymorphism and periodontitis were searched up to Feb.

ADAM10 overexpression in human non-small cell lung cancer correlates with cell migration and invasion through the activation of the Notch1 signaling pathway.

A disintegrin and metalloproteinase 10 (ADAM10) was identified as a key protease in the ectodomain shedding of various substrates, such as Notch1 protein, ErbB2 and E-cadherin, which are important in the development of non-small cell lung cancer (NSCLC). The aim of this study was to investi-gate the role of ADAM10 in NSCLC metastasis.We characterized the expression of ADAM10 and Notch1 in human NSCLC tissues in vivo.
