Long-term stability following orthodontic treatment required long-term retention. Compliance with removable retention regimens is variable so some practitioners favour fixed retainers. The aim of this study was to compare the survival of mandibular lingual retainers placed using either chemical or photo polymerization after orthodontic treatment. Patients who had completed orthodontic treatment with no active caries, [read the full story…]
The peg-shaped lateral incisor is one that has an incisal mesiodistal width of the tooth crown shorter than the cervical width. This can lead to aesthetic, orthodontic and periodontal problems for the patient. The aim of this review was to assess the prevalence in relation to race, sex, population type and continent of origin. The [read the full story…]
White spot lesions (enamel decalcification) is an adverse effect of orthodontic treatment and may be present in up to 50% of patients following removal of fixed appliances. Topical fluorides have been shown to reduce decalcification and the use of fluoridated bonding composites and elastomerics have also been tested. The aim of this study was to [read the full story…]
Two new protocols for Cochrane reviews have appeared on this latest release of the Cochrane Library. The first is Fleming PS, Pandis N, Johal A, El-Angbawi A, Fedorowicz Z.

Light systems to cure orthodontic bonding materials to attach orthodontic brackets have been in use for many years. In recent years, alternatives to halogen lights, including light emitting diodes (LEDs) and plasma lights, have been developed. The aims of this review was to compare bracket failure risks and times taken to place attachments with 3 [read the full story…]
This is the latest update of a Cochrane review which aims to assess the effects of initial arch wires for alignment of teeth with fixed orthodontic braces in relation to alignment speed, root resorption and pain intensity. The Cochrane Oral Health Group’s Trials Register, CENTRAL, Medline and Embase databases were searched. Handsearching of a number [read the full story…]
This ADA critical summary looks at a 2012 review by van Vlijmen et al of the evidence to support the use of cone-beam computed tomography (CBCT) in orthodontics The reviewer highlights the extensive range of databases searched for the use of CBCT for orthodontic purposes. There was also an independent assessment of study quality. The [read the full story…]
White spot lesions (WSLs) are a common adverse effect of orthodontic treatment. The incidence of these lesions is high with some estimates as high as 97%. The aim of this review was to assess the evidence regarding the effect of remineralizing agents on post-orthodontic WSLs and to evaluate which remineralizing agents are effective for the [read the full story…]
The class II malocclusion is a common problem that people attend for orthodontic treatment. The main aim of this review was to assess whether Class II elastics are effective in correcting Class II malocclusions PubMed, Scopus, Web of Science, Embase, Medline, and Cochrane databases, were searched. This was complemented by a hand search, with no [read the full story…]
Following orthodontic treatment almost every patient will require a period of retention without which there is a tendency for teeth to return to their initial position. The aim of this trial was to compare three different retention methods. Patient s completing a first course of orthodontic treatment were randomized into three retention methods: vacuum-formed retainer [read the full story…]
