Objective: The aim of this study was to characterize the chemical elements and morphology of filler particles of conventional and low-shrinkage composite resins. The main components were identified by means of energy-dispersive X-ray spectroscopy (EDX) microanalysis; whereas filler particles were analyzed morphologically by scanning electron microscopy (SEM). Methods: Four composite resins were studied: two conventional ones (Heliomolar and Tetric N-Ceram, Ivoclar VivadentTM) and two...
By the end of the nineteenth century, London was one of the largest cities in Europe. With the Industrial Revolution, thousands of people moved out to the metropolis, which was conducive to the outbreak of one of the greatest epidemics in human history.
As I have written in my first editorial, when I took up the position of editor-in-chief of Dental Press Implantology, there was a major challenge to be faced: raising the journal’s quality by seeking to publish the best articles. We have done a great job by renewing our editorial board (to which I thank publicly for the time dedicated and priceless compliance) and establishing partnerships with professional associations, such as the International Team for Implantology (ITI), which has...
Deciduous is an adjective that describes something that falls off, it is caducous or confined. Deciduous makes reference to the parts of plants or animals that fall off before the usual time at a certain stage of development in the life cycle as a whole. Caducous refers to something that is about to fall off, something that has lost the strength and vigor or something that has been annul and, therefore, has a limited life span. In Latin, the verb decidere means to fall off, to perish or to...
I t is my pleasure to contribute to the new Journal of Clinical Dentistry and Research through this editorial.
Objective: The aim of this study was to radiologically evaluate bone remodeling of sinus graft performed with autogenous bone harvested from the iliac crest or from the cranial vault. Methods: Radiographs of 24 individuals subjected to maxillary sinus lift were assessed at the following stages: preoperative (T1), immediate postoperative (T2) and late postoperative (T3). Measurements were performed on panoramic radiographs to determine the remaining alveolar bone (T1), from the alveolar ridge...
Introduction: The literature has shown that colonization of the implant-abutment interface (IAI) by microorganisms may result in peri-implantitis and bone loss. Objective: The aim of this in vitro study was to analyze the sealing properties of flowable silicone at this interface in external hexagon implants undergoing loading tests. Methods: Two groups of external hexagon implants (n = 10) were filled with blue dye. In the control group, no material was applied to the implant-abutment...
Abstract: Technology has never been so present in Dentistry as it is today. From diagnosis to clinical procedures, we count on technology that allows us to be more precise and assertive in our treatments. Objective: This article aims to show how technology is changing concepts in Orthodontics, Surgery and Restorative Dentistry.
Introduction: Insufficient curing of dual-cure cements used for cementation of intraradicular posts may compromise the restorative retention system, which could lead to restoration failure. Objective: This study aimed at assessing the microhardness of dual-cure resin cements used for glass fiber posts (DT Light PostTM) cementation, whether subjected or not to a light-curing source, according to the different root thirds. Methods: Forty bovine incisors roots were selected and divided into eight...
Problems related to complications associated with dental implants in esthetic zones have become increasingly common in the clinical practice. Among those problems, the most common mistakes include: malposition of the implant, inadequate restoration contour, and lack of adequate treatment planning. The description of the case presented in this article shows a clinical sequence, from surgery to prosthetic procedures, employed to retreat two implants in the anterior maxilla, both of which had been...
Some requirements are critical to achieve a composite resin restoration that resembles, in every single aspect, the natural tooth. Steps such as the selection of dental composites used, clinical application as well as finishing and polishing are essential. Careful finishing and polishing affect not only aesthetics, but also health. There is a wide variety of drills, polishers and pastes available on the market. Understanding the best sequence and the correct application of those products are...
