Introduction A great number of techniques have been used for bonding orthodontic brackets to the tooth surfaces. Glass ionomer cements are frequently used material for this purpose. The aim of this study was to measure the shear bond strength of orthodontic brackets bonded with glass ionomer cement Ortho Fuji LC and remained adhesive on the enamel surface after brackets debonding. Material and ...

The literature describes transillumination as a means of curing orthodontic light-cured composite adhesive. The literature also recommends a 2 to 3 times increase in light exposure time when light curing using transillumination. The purpose of this study was to determine the transmittance of the curing light through human enamel and the effect of transillumination on the bond strength of orthod...

Objectives: This study was aimed to compare the mean shear bond strength of four orthodontic bonding materials used for bonding orthodontic brackets. Self-cure composite adhesive (Reliance orthodontics), light cure composite adhesive (Transbond XT, 3M Unitek), light cure with self-etching primer (SEP), Transbond XT and Transbond Plus, 3M Unitek and light cure with moisture-insensitive primer (M...

The fluoride level in saliva is considered an important parameter in caries prevention. Elevation of the salivary fluoride level by a fluoride-releasing orthodontic bonding adhesive would most likely be beneficial in the prevention of enamel caries. In this study, the fluoride level in saliva was measured after bonding brackets with a visible light-curing adhesive containing fluoride (12.4 wt% ...

INTRODUCTION Treatment with fixed orthodontic appliances requires the application of adhesive systems to enable secure fastening of brackets and retainers to the surface of tooth enamel. The orthodontic bonding systems are similar in terms of chemical composition to dental filling materials, the chemical stability of which is not satisfactory. Particularly alarming is the release of bisphenol A...

Introduction: The aim of this study was to compare the microleakage of beneath the orthodontic brackets bonded with 3 different bonding techniques and evaluate the effect of thermocycling. Methods: One hundred and twenty premolars were randomly divided into 6 groups, received the following treatment: group 1: 37% phosphoric acid gel+Unite primer+Unite adhesive, group 2: 37% phosphoric acid gel+...

statement of problem: bracket de-bonding during initial orthodontic archwire placement immediately after bracket set up or following re-bonding a single bracket can be a clinical concern. purpose: the aim of this in vitro study was to assess the effect of time on the shear bond strength of a no-mix orthodontic composite adhesive. materials and methods: seventy freshly extracted human upper firs...

the purpose of this study was to evaluate the shear bond strength (sbs) of orthodontic brackets bonded with two types of nano-composites in comparison to a conventional orthodontic composite.sixty extracted human first premolars were randomly divided into 3 groups each containing 20 teeth. in group i, a conventional orthodontic composite (transbond xt) was used to bond the brackets, while two n...

INTRODUCTION: The use of flowable composites as an orthodontic bonding adhesive merits great attention because of their adequate bond strength, ease of clinical handling and reduced number of steps in bonding. OBJECTIVE: The aim of this Randomized Controlled Trial was to comparatively evaluate over a 6-month period the bond failure rate of a flowable composite (Heliosit Orthodontic, Ivoclar ...

Appearance does count at any age. Esthetic compromise repels adult patients from accepting traditional metallic look orthodontic treatment. Tooth colored brackets and wires gained popularity for a few decades but gradually declined owing to its own disadvantages. Lingual orthodontic appliances brought paradigm shift, but could not got prevalent because of tedious bracket positioning, insufficie...
