(2020-01-01)
Objective: This clinical study sought to evaluate the effectiveness of passive ultrasonic activation (PUA) in eliminating microorganisms in primary endodontic infection (PEI) after instrumentation of root canals using ...
Efeito da ativação ultrassônica de novos cimentos endodônticos na resistência de união e qualidade da obturação de canais radiculares
(Universidade Federal de Santa MariaBrasilOdontologiaUFSMPrograma de Pós-Graduação em Ciências OdontológicasCentro de Ciências da Saúde, 2018-08-15)
The aim of this study was to investigate the effect of ultrasonic activation (UA) of three endodontic sealers on the bond strength to root dentin and root canal filling quality. Ninety-six bovine incisors were selected. ...
Calcium hydroxide root canal sealers - Histopathologic evaluation of apical and periapical repair after endodontic treatment
(Williams & Wilkins, 1997-07-01)
Eighty root canals of the premolars of 4 dogs, with vital pulp, were instrumented and filled during the same session with the Sealapex, CRCS, Sealer 26, and Apexit sealers, the animals were sacrificed 180 days after root ...
Crown-down preflaring in the determination of the first apical file
(Sociedade Brasileira de Pesquisa Odontológica, 2010)
In this study, scanning electron microscopy (SEM) was used to evaluate the adaptation of the first apical file after preflaring in mesiobuccal (MB) and mesiolingual (ML) canals of mandibular molars considering the tactile ...
The impact of apical patency in the success of endodontic treatment of necrotic teeth with apical periodontitis: A brief review
(2016-12-01)
Accumulation of soft tissue or dentinal remnants in the apical region is a common event that can cause blockage of root canals. This event can be avoided if apical patency is performed during the root canal shaping procedures. ...
Hand and ultrasonic instrumentation for orthograde root canal treatment of permanent teeth
(Faculdade De Odontologia De Bauru - USP, 2010)
Root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. Removal of the necrotic tissue remnants and cleaning and ...
Effect of root canal status on periodontal healing after surgical injury in dogs.
(Munksgaard Int Publ Ltd, 1994-04-01)
This study was carried out to observe if the status of the root canal might influence the healing process of surgically prepared experimental periodontal lesions. Forty tooth roots from four dogs were divided into four ...
