Successful final restoration is important for the long term success of root canal treatment. A lack of adhesion in a final restoration could result in apical or coronal leakage that causes problems in the root canal treatment. Endodontically-treated teeth frequently require extensive restorations with post-core system. ABSTRACT The Influence of AH-26 and Zinc Oxide-Eugenol Root Canal Sealer on ...

The restoration of teeth utilising composites still presents a myriad of clinical challenges for the dental clinician. This is especially true for extensively broken down teeth and as well, those teeth which have been accessed endodontically. Fibre posts such as the quartz Macro-Lock Illusion X-RO post (Recherches Techniques Dentaires—RTD) UniCore Fiber post (Ultradent), and DT Light-Post (RTD)...

OBJECTIVE The purpose of this study was to introduce a new method for quantitative testing of endodontic leakage. STUDY DESIGN Eighty straight maxillary anterior teeth were divided randomly into 3 experimental groups of 20 samples each and 2 control groups. The experimental groups were prepared using the modified double-flared technique and obturated by lateral compaction of cold gutta-percha...

introduction: root canal obturation seals the root canal system to prevent re-entry and/or growth of microorganisms. the provision of an appropriate restoration to coronally seal the access cavity affects the success of endodontic treatment. the purpose of this study was to evaluate the coronal microbial leakage in root canals that were either filled by lateral compaction, guttaflow or warm ver...

introduction: the aim of this study was to compare the sealing ability of real seal (rs) and gutta-percha (gp). materials and methods: forty nine extracted human maxillary central incisors were used. the coronal part of each tooth was removed; the root canal was prepared using the crown down technique and apical enlargement to rotary file # 40. the specimens were randomly divided in to 3 groups...

The term 'craniofrontonasal dysplasia' (CFND) was introduced by Cohen' in 1979 when describing a 14 year old girl with coronal craniosynostosis, hypertelorism, limitation of shoulder movement, and digital abnormalities. The child's mother was also affected. In the same volume of Birth Defects, Slover and Sujansky2 reported similar findings in three female sibs, both of whose parents had hyperte...

INTRODUCTION A coronal barrier in root-filled teeth is one of the most effective methods for prevention of coronal microleakage. The aim of this study was to compare coronal microleakage of three materials [light-cured glass-ionomer (GI), mineral trioxide aggregate (MTA), and composite resin] as coronal barriers. MATERIALS AND METHODS A total of 188 intact maxillary incisors were used. After ...
