Endodontic failures associated with poor quality of endodontics respond favorably to retreatment. Nevertheless, under certain clinical conditions, apicoectomy should be the preferred procedure. A retrospective survey of 200 roots that were referred for apical surgery revealed that 83% of the roots were inadequately obturated, including 8.5% with no root canal filling at all. In 49 of the roots ...

The aim of this study was to determine different causes of endodontic treatment failure in patients who approached the Department of Operative Dentistry, Khyber College of Dentistry, Peshawar, for retreatment. This study was carried out from December 2009 to February 2010 and included seventy five patients of both genders with different post endodontic treatment complaints. Clinical and radiogr...

the main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. failure to find and fill a canal contributes toward the failure of endodontic therapy .the root canal anatomy of mandibular first molars is complex. studies of the morphologic structure of root canal systems have d...

INTRODUCTION Endodontic treatment in pulpless immature teeth is challenging due to the lack of an apical stop. Insertion of an apical plug is an alternative to conventional long-term apexification with calcium hydroxide. The aim of this study was to compare the apical microleakage of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement as apical plugs with three different ...

One-visit root canal treatment (OV-RCT) aims to preserve damaged teeth by fulfilling the principles of endodontic triad (cleaning and shaping, sterilizationand obturation) which are completed in OV; advantage is lower risk bacterial contamination, shorter time without compromising quality oftreatment results. This case report discusses OV-RCT man-dibular right second molar. A 23-year-old woman ...
