white spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. long-lasting antibacterial properties of orthodontic cements can reduce this phenomenon. the aim of this research was to compare antimicrobial activity of three commercial glass ionomer cements with three commercial zinc phosphate cements, over time, against streptococcus mutans and candida albicans. dir...

Background: New materials that are introduced in operative dentistry can potentially have orthodontic applications. One of the most important advances in the dental material field is the application of nanotechnology to resin composites. Recently, new fillers with size ranging from approximately 5-100 nm have been developed. These materials could thus be considered as precursors of nanocomposit...

increased number of adult patients requesting orthodontic treatment result in bonding bracket to ceramic restorations more than before. the aim of this study was to evaluate and compare the shear bond strength of orthodontic brackets bonded to two types of ceramic bases with conventional orthodontic bonding resin and a new nano-filled composite resin.twenty four feldespathic porcelain and 24 li...

INTRODUCTION The indirect bonding technique optimizes fixed appliance installation at the orthodontic office, ensuring precise bracket positioning, among other advantages. In this laboratory clinical phase, material and methods employed in creating the transfer tray are decisive to accuracy. OBJECTIVE This article describes a simple, efficient and reproducible indirect bonding technique that ...

Objective The aim of this study was to assess whether LPS adheres to orthodontic adhesive systems, comparing two commercial brands. Material and Methods Forty specimens were fabricated from Transbond XT and Light Bond composite and bonding agent components (n=10/component), then contaminated by immersion in a bacterial endotoxin solution. Contaminated and non-contaminated acrylic resin sample...

BACKGROUND Orthodontic treatment is taken as a painful procedure by most of the patients. The pain can be experienced during different procedures like separator placement, banding, bonding, extraction as well as arch wire activation and debonding. There are very few studies done on the anticipated pain and pain experienced among mentioned orthodontic procedures. OBJECTIVES To compare the anti...

This prospective, in vivo study compared bond failure and enamel decalcification with a cyanoacrylate bracket bonding system (SmartBond, Gestenco International, Gothenburg, Sweden) and a traditional light-cured composite system (Light Bond, Reliance Orthodontic Products, Itasca, Ill). A total of 327 teeth were evaluated after a period of 12 to 14 months; 163 experimental teeth were bonded with ...

The aim of this study was to compare the in vitro bond strength to enamel measured in shear of the light-activated bonding agent Heliosit-Orthodontic with the shear bond strength of the two-paste bonding resin Concise and the 'no-mix' bonding resin Right-On. In a number of separate tests involving 205 teeth and 267 bonds, the Heliosit-Orthodontic is shown to form a stronger bond to canine teeth...

Orthodontic extrusion is usually performed by means of a fixed orthodontic appliance that utilizes arch wire attached to adjacent teeth and transfers the desired force by elastic from the wire to the root. However, clinicians often encounter cases where the bonding required for tooth traction is not possible because the adjacent teeth have been restored with ceramic or veneer. The purpose of th...
