The enigmatic Otway odd-clawed spider (Progradungula otwayensis Milledge, 1997, Gradungulidae, Araneae): Natural history, first description of the female and micro-computed tomography of the male palpal organ
(Pensoft Publishers, 2013-09-25)
The recently described cribellate gradungulid Progradungula otwayensis Milledge, 1997 is endemic to the Great Otway National Park (Victoria, Australia) and known from only one male and a few juvenile specimens. In a recent ...
Designed for resistance to puncture: The dynamic response of fish scales
(ELSEVIER SCIENCE BV, 2019-01-01)
Natural dermal armors are serving as a source of inspiration in the pursuit of “next-generation” structural materials. Although the dynamic strain response of these materials is arguably the most relevant to their performance ...
Filling ability and flow of root canal sealers: A microcomputed tomographic study
(2020-09-01)
This study evaluated by micro-computed tomography (μCT) the filling ability in curved root canals, besides the flow of AH Plus (AHP) and Neo MTA Plus (NMTAP) sealers using different methodologies. Mandibular molars mesial ...
Micro-ct Evaluation Of The Radioprotective Effect Of Resveratrol On The Mandibular Incisors Of Irradiated Rats
(Sociedade Brasileira de Pesquisa OdontologicaSão Paulo, 2016)
Polymerization shrinkage of bulk fill composites and its correlation with bond strength
(2018-05-01)
The present study aimed to evaluates polymerization shrinkage (PS) using microcomputed tomography (μCT) and microtensile bond strength (μTBS) in bulk fill composites (BFC) and conventional class I restorations as well as ...
Effect of different dimensions of test samples on the volumetric change assessment of endodontic materials
(2021-01-01)
New methodologies using micro-CT to evaluate solubility besides dimensional and morphological changes of endodontic materials are proposed. However, there is no standardization in the methods. The aim of this study was to ...
Effect of obturation technique using a new bioceramic sealer on the presence of voids in flattened root canals
(2021-01-01)
The aim of this study was to evaluate the filling ability of a new ready-to-use calcium silicate-based sealer using thermoplastic or single-cone technique in flattened root canals. Twenty-four flattened distal canals of ...
Solubility, porosity and fluid uptake of calcium silicate-based cements
(Univ Sao Paulo Fac Odontologia Bauru, 2018-01-01)
Objective: To evaluate the absorption/fluid uptake, solubility and porosity of White mineral trioxide aggregate (MTA) Angelus, Biodentine (BIO), and zinc oxide-eugenol (ZOE). Material and Methods: Solubility was evaluated ...
Physicochemical properties and bioactive potential of a new epoxy resin-based root canal sealer
(2019-11-01)
The aim of this study was to evaluate physicochemical properties and bioactive potential of Sealer Plus, in comparison with MTA Fillapex, Sealapex and AH Plus. Setting time, flow, and radiopacity were evaluated based on ...
