(University of Pretoria, 2023)The purpose of this in vitro study was to evaluate and compare obturation quality and preparation times after root canal shaping between manual, rotary and reciprocating files during pulpectomy treatment in primary molars. ...
-
(University of Pretoria, 2015)The aim of this in vitro study was to investigate the canal centering ability and apical root canal transportation of pre-curved stainless steel K-files, the ProGlider file and GFiles after glide path enlargement in ...
-
(University of Pretoria, 2017)The risk of cross-contamination validated the need to assess the adequacy of cleanliness of dental instruments following decontamination procedures. Neither the extent of single-use nor the efficacy of decontamination of ...
-
(University of Pretoria, 2015)Objectives: To evaluate the surface roughness of a nanocomposite and a microhybrid composite after polishing the composites with different polishing systems. Key words: Polishing, surface roughness, microhybrid composite, ...
-
(University of Pretoria, 2017)The aim of this in vitro study was to investigate various glide path preparation instruments followed by root canal preparation with the reciprocating Primary WaveOne Gold instrument in curved mesial root canals of extracted ...
-
(University of Pretoria, 2015)Objectives: This in vitro study investigated and compared the fracture strength and behaviour patterns of a conventional posterior composite resin, a composite resin reinforced with nano-scale electrospun glass-fibres ...
-
(University of Pretoria, 2013)The preparation of a glide path prior to the use of rotary nickel titanium instrumentation reduces torsional stress and the risk of rotary nickel titanium instrument separation. The objective of this in vitro study was ...
-
(University of Pretoria, 2009)After cleaning and shaping of the root canal the final objective of the endodontic procedure is to obtain a three-dimensional obturation of the root canal space with a fluid-tight seal at the apical foramen. The objective ...
-
(University of Pretoria, 2013)Introduction: Bacteria are the most common pathogens responsible for pulpal necrosis and periapical disease conditions. The importance of eradicating bacteria and their endotoxic by-products has been highlighted in numerous ...
-
(University of Pretoria, 2023)Introduction: Bioceramic sealers are receiving substantial attention because of their favourable physicobiological properties. Studies have shown that the use of materials containing calcium-silicates results in the formation ...
-
(University of Pretoria, 2013)Introduction: The aim of this in vitro study was to determine the influence of two glide path preparation methods on the fracture rate of the Primary 25/08 WaveOne reciprocating instrument. The number of simulator ...
-
(University of Pretoria, 2008)Resin based composite is currently one of the most popular dental restoratives. Used as a direct restorative material, it displays many beneficial properties such as excellent micromechanical bonding to enamel, polishability ...
-
(University of Pretoria, 2020)Introduction: An extensive knowledge of dental root and canal anatomy is essential to clinicians performing endodontic treatment. It is well-known that dental anatomy may be complex and display significant variation. ...
-
(University of Pretoria, 2010-03-01)Self-etching dentine bonding agents are a recent addition to the choice of bonding agents which a clinician has available to bond resin restorations to tooth structure. The so-called ‘traditional’, total-etch fourth and ...
