Orthodontic bonding – failure rates with different techniques

shutterstock_81157801-orthodontic appliance

This review of the failure rates of different orthodontic bonding materials included 80 studies with 34 contributing to the quantitative component. The findings suggest little difference between the self-etch primer and conventional acid-etch primer and a poorer performance for glass ionomer compared with self-cure resin. However the findings should be interpreted cautiously because of the low certainty of the available evidence.

Etching time and bonding of adhesive systems to dentine of primary teeth


This review the influence of reducing the etching time on the dentine of primary teeth for bonding with etch-and-rinse and self-etching adhesive systems included 8 laboratory studies. The findings suggest that that reductions in acid-etching and primer application did not impact the immediate bond strength.

Laser preparation of tooth surfaces before fissure sealant placement

Fissure sealant

This review of laser preparation compared to other types of tooth surface preparation before fissure sealant placement included 5 RCTs. While the review suggested that retention rates with laser preparation were similar to acid etching the included studies were small and at high risk of bias. Thefore the findings should be considered very cautiously.

Little evidence available on the effectiveness of SLA and SLActive dental implants


In recent years a number of variations to implant surfaces have been introduced as it is considered that surface topography has an important role. Modifications have included, sandblasting, acid-etching, grit- blasting, anodisation, discrete calcium-phosphate crystal deposition, coatings with biological molecules and chemical modification. The aim of this review was to assess he survival percentage, clinical [read the full story…]

Review suggests that glass ionomers had best retention rates in non-carious cervical lesions


The aetiology of non-carious cervical lesions  (NCCLs) has not been fully clarified but they are characterised by a slow and gradual loss of mineralized dental tissue in the absence of dental caries. This results in a saucer or wedge-shaped defect that appears along the cementum–enamel Junction.   The aim of this review was to assess the [read the full story…]

1-step bonding technique for orthodontic appliances provides modest time saving compared with 2-stage techniques

The application of dental bonding to orthodontics had had a significant impact on with  bonded appliances replacing multi-banded systems.  With the development of bonding systems there is increasing interest in 1-step systems.  These self-etch systems (SEPs) are used by about 30% of American practitioners and are thought to reduce chair-side time.   The aim of this [read the full story…]
