Efficacy of automated versus hand instrumentation during root canal retreatment: an ex vivo study.
AIM To compare automated and manual instrumentation techniques for removing filling material from root canal walls during root canal retreatment. METHODOLOGY One hundred extracted human single-rooted teeth were root filled and stored. Specimens were divided into two groups: group A, Endofill plus gutta-percha; group B, Sealer 26 plus gutta-percha. The filling material was removed using the fo...
متن کاملEffect of smear layer on the apical seal of endodontically treated teeth: an ex vivo study.
AIM The purpose of this study was to evaluate the effect of smear layer on apical seal of endodontically treated teeth. MATERIALS AND METHODS Sixty freshly extracted human maxillary central incisor teeth were selected and were randomly divided into two experimental groups. Group A of 25 teeth and group B of 25 teeth and a control group of 10 teeth. Cleaning and shaping of the root canals were...
متن کاملLess extrusion debris during the retreatment of curved canals using twisted files with higher rotational speeds: an ex vivo study
BACKGROUND Debris extrusion from the apical foramen can be problematic in severely curved canals. This study aimed to assess the use of Twisted Files (TF) at different rotational speeds during retreatment, compared with manual technique using Triple-Flex Files (TFF). METHODS Forty-eight mesiobuccal root canals were randomized to four groups (n = 12 per group). In groups A, B, and C, gutta-per...
متن کاملComparative Sem Evaluation of Three Solvents Used in Endodontic Retreatment: an Ex Vivo Study
This study compared, by scanning electron microscopy (SEM), the efficacy of three solvents on the removal of filling materials from dentinal tubules during endodontic retreatment. Forty human maxillary canines with straight canals were prepared according to a crown-down technique and enlarged to a#30 apical file size, before obturation with gutta-percha and a zinc-oxide-eugenol based sealer. Th...
متن کاملEx-vivo Sealing Ability of Different Thicknesses of White and Gray Angelus MTA as an Intra-orifice Barrier in Endodontically Treated Teeth
Introdouction: It is important for the clinician to be aware regarding the necessary thickness of materials used as intra-orifice coronal barriers to prevent microleakage. The purpose of this in vitro study was to compare coronal microleakage of three different thicknesses of white and gray Angelus mineral trioxide aggregate (WAMTA, GAMTA). Materials and methods: A total of 66 canals of extrac...
