Limited evidence for the role of lateral cephalometric radiographs in orthodontic treatment

shutterstock_1033530

Lateral cephalometric radiographs were introduced in the 1930s and together with their related analysis have been a standard element of orthodontic treatment planning.  However their role in assessment and treatment planning has been questioned.    The aims of this review were to evaluate the existing evidence about the validation of lateral cephalometric radiograph in orthodontics and [read the full story…]

The minimum record set required for orthodontic diagnosis and treatment planning remains undefined

shutterstock_1033530

Prior to orthodontic diagnosis a range or records may be obtained, typically these include, dental models, radiographs and facial and intra-oral photographs. Advances in digital technology means that 3D technology is also available. However, the role and use of any or each of these elements of the record set is unclear. Therefore the aim of [read the full story…]

Fixed banded orthodontic treatment is commonplace not only amongst children by but increasingly in adults.  Being able to successful bond these brackets to the teeth during treatment is a one factor for successful treatment.   The aim of this review was to compare the effects of different dental etchants and different etching techniques for the bonding [read the full story…]

Review suggests that intraoral appliances are more effective than headgear in distalising upper first molars

Moving the upper molars backwards during orthodontic treatment is sometimes necessary.  Appliances used for this are categorized in to intraoral or extraoral appliances. External headgear is one of the commonest distalising approaches.  The aim of this Cochrane review was to assess the effects of orthodontic treatment for distalising upper first molars in children and adolescents.

Prominent lower front teeth (reverse bite; under bite; Class III malocclusion) are more common in oriental (15%) and black races (10%) and relatively uncommon in Caucasian (4%) populations. Several orthodontic approaches have been suggested to correct this and the aim of this Cochrane review was to assess the effects of orthodontic treatment for prominent lower [read the full story…]

Evidence on the adverse effects of interproximal dental stripping is limited

shutterstock_51503758

Interproximal dental stripping or interproximal enamel reduction (IER) was originally suggested back in the 1940s as a method of gaining space in the lower incisor region.  The aim of this review was to investigate the enamel roughness resulting from IER as well as the cariogenicity of IER in orthodontic patients. The databases, PubMed, Scopus, The [read the full story…]

Study suggests that text reminders may improve oral hygiene compliance during orthodontic treatment

Compliance with oral hygiene measures during orthodontic treatment is important in order to prevent white spot lesions (WSL) developing.  The aim of this study was to determine if there is a relationship between reminding patients of the importance of oral hygiene via weekly text message reminders sent to their parents/guardians and demonstrated oral hygiene compliance.

No randomised controlled trial evidence on effective methods to treat relapse of lower front teeth following orthodontic treatment

shutterstock_150291182

The tendency for teeth to return to their pre-treatment following orthodontic treatment (relapse) is more common for the lower front teeth.  Ten years after orthodontic treatment between 30-50% of patients no longer have the initial post-treatment alignment and after 20 years only 10% maintain that alignment. The aim of this review was to assess the [read the full story…]

Trial finds no changes in arch dimensions following orthodontic treatment with conventional brackets and either active or passive self-ligation

To produce alignment without extraction. It has been suggested that passive self-ligating brackets can introduce specific, uniquely stable arch dimensional changes. The aim of this trial was to quantify maxillary arch dimensional changes and maxillary incisor and molar inclination changes during orthodontic alignment by directly comparing a passive self-ligating bracket, an active self-ligating system and [read the full story…]

Open or closed surgical technique for displaced palatal canines did not affect periodontal outcomes in short term

It is reported that around 13% of upper canines can be displaced, the majority of these being palatally displaced.  Controversy exists on whether a closed techniques of moving a canine into its correct position beneath the palatal mucosa (closed technique) is preferential to an open technique which involves moving the canine into its correct position [read the full story…]
