Morphometrical analysis of cleaning capacity of a hybrid instrumentation in mesial flattened root canals
(Wiley-Blackwell, 2011-12-01)
The cleaning capacity of hybrid and rotary instrumentation techniques in mesial flattened canals of mandibular first molars was evaluated by morphometrical analysis in this study. Twenty human mandibular first molars were ...
Effectiveness of rotary or manual techniques for removing a 6-year-old filling material
(2010-08-20)
The aim of this study was to evaluate the effectiveness of manual and rotary instrumentation techniques for removing root fillings after different storage times. Twenty-four canals from palatal roots of human maxillary ...
A comparison of molar root canal preparation using stainless-steel and nickel-titanium instruments
(1999-12-01)
Fifty-four extracted human mandibular molars were embedded and sectioned at two levels. The reassembled mesial root canals were prepared with stainless-steel hand K-files (Flexofiles) and either Nitiflex or Mity nickel-titanium ...
Calcium hydroxide intracanal dressing removal with different rotary instruments and irrigating solutions: A scanning electron microscopy study
(2010-11-30)
This study evaluated the efficacy of 2 types of rotary instruments employed in association with sodium hypochlorite (NaOCl) or EDTA in removing calcium hydroxide (CH) residues from root canals dentin walls. Forty-two ...
Reaction of dogs' teeth to root canal filling with mineral trioxide aggregate or a glass ionomer sealer
(1999-11-01)
This study was conducted to observe the reaction of apical tissues of dogs' teeth after root canal filling with gutta-percha and mineral trioxide aggregate (MTA) or a glass ionomer (Ketac-Endo) as a sealer. The root canals ...
Apical and periapical repair of dogs' teeth with periapical lesions after endodontic treatment with different root canal sealers.
(2003-01-01)
The aim of this study was to evaluate the apical and periapical repair after root canal treatment of dogs' teeth with pulp necrosis and chronic periapical lesion using different root canal sealers. After periapical lesion ...
Comparison of resin push-out strength to root dentin of bovine- and human-teeth
(2009-07-01)
Aim : To compare the push-out strength of bovine- and human-root dentin and, thus, evaluate the suitability of bovine-root dentin to substitute human-root dentin for bond strength testing. Materials and Methods : Ten ...
CT study of the performance of reciprocating and oscillatory motions in flattened root canal areas
(Sociedade Brasileira de Pesquisa Odontológica - SBPqO, 2015)
Calcium hydroxide root canal dressing. Histopathological evaluation of periapical repair at different time periods.
(2002-03-01)
The objective of this study was to evaluate periapical and apical repair using calcium hydroxide root canal dressings for different lengths of times in teeth with induced chronic periapical lesions. A total of 61 root ...
