background and aims. incorporation of nano-particles to orthodontic bonding systems has been considered to prevent enamel demineralization around appliances. this study investigated cytotoxicity of transbond xt adhesive containing 1 wt% titanium dioxide (tio2) nano-particles. materials and methods. ten composite disks were prepared from each of the conventional and tio2-containg composites and ...

in recent years, newly developed solvent-free dental adhesives have been introduced. the aim of this study was to evaluate the marginal integrity of a new one-step solvent-free self-etch adhesive and to compare it with a commonly used two-step self-etch adhesive as the gold standard.class v cavities (2×4×1.5 mm) were prepared on the buccal aspects of 28 human premolars. the cervical margins of ...

Nowadays, several adhesive systems are used in dental restoration and they are evaluated by clinical research. In vitro evaluations are often made by means of traditional observation techniques (for example scanning electron microscope (SEM), while 3D cone-beam microtomography technique (3D micro-CT), that can be able to generate 3D sample images without any sample treatment during acquisition ...

PURPOSE To assess the effects of three different dental adhesive systems on the formation of secondary root caries, in vitro, with a standardized interfacial gap in a filled cavity model. METHODS 40 sound human molars were selected and randomly assigned to four experimental groups: Clearfil SE Bond (CSEB), Xeno III (X-III), Scotchbond Multi-Purpose Plus (SBMP) and negative control (NC) withou...

OBJECTIVE Recurrent caries at the margins is a primary reason for restoration failure. The objectives of this study were to develop bonding agent with the double benefits of antibacterial and remineralizing capabilities, to investigate the effects of NACP filler level and solution pH on Ca and P ion release from adhesive, and to examine the antibacterial and dentin bond properties. METHODS Na...

Every so often a new material, technique, or technological breakthrough spurs a paradigm shift in the way dentistry is practiced. The development and evolution of reliable enamel and dentin bonding agents is one such example. Indeed, the so-called "cosmetic revolution" in dentistry blossomed in large part due to dramatic advances in adhesive technology. It is the ability to bond various materia...

BACKGROUND At the end of fixed orthodontic treatment, the remnant of adhesive should be eliminated from the tooth surface. The purpose of this study was to compare the effect of three methods of removing adhesive on enamel surface roughness, dental pulp temperature, and also on the time spent. MATERIALS AND METHODS The brackets on 90 extracted teeth were debonded using bracket removal pliers....

The aim of this clinical report is to describe the management of a young patient, affected by ectodermal dysplasia, during a nine-year period. Dental treatment can vary depending on the severity of the disease (tooth size, morphology, and amount of available alveolar bone). New technologies, such as adhesive dentistry, and new materials, such as composite resin, represent current options in the...
