Multidisciplinary management of missing maxillary central incisors in children and adolescents.

Missing maxillary central incisors can impact a patient's psychological wellbeing and smile aesthetics. Comprehensive management of such cases requires a multidisciplinary team approach, often involving orthodontic, paediatric and restorative dental teams. This paper summarises the various management options for these complex patients.

Preventing white spot lesions with fluoride pastes.

Design Randomised controlled trial.Study population Patients undergoing routine orthodontic treatment, aged 12 years and older, were randomly allocated to use either Clinpro 5000, Clinpro Tooth Crème or MI Paste Plus for 4 months.Data Analysis Three-way analysis of variance (ANOVA) was used to analyse the Enamel Decalcification Index (EDI) scores of the maxillary and mandibular arches from the right first premolar to the left first premolar at 0.

The Ethics of Interproximal Reduction.

Interproximal reduction (IPR) has become particularly popular with the use of removable aligners. Clinical and ethical factors concerning the use of interproximal reduction to facilitate orthodontic alignment are discussed. CPD/Clinical Relevance: An understanding of the aetiological factors of a malocclusion is essential to enable full discussion of the risks and benefits, or the alternatives to IPR.

Cone beam computed tomography--current understanding and evidence for its orthodontic applications?

Cone beam computed tomography (CBCT) is a fast developing technology which provides relatively low-dose, high spatial resolution imaging of the craniofacial complex in three dimensions (3D). During the past decade, the number of CBCT-related publications in the literature has increased significantly, but the crucial question is whether this technology leads to improved outcomes. In this paper, the literature is reviewed and the main applications of CBCT in orthodontics are highlighted, as well as the current evidence and understanding in each area.

Digital versus plaster study models: how accurate and reproducible are they?

Objective: To compare measurements of occlusal relationships and arch dimensions taken from digital study models with those taken from plaster models.

Design: Laboratory study

Setting: The Orthodontic Department, Kettering General Hospital, Kettering, UK Methods and materials: One hundred and twelve sets of study models with a range of malocclusions and various degrees of crowding were selected. Occlusal features were measured manually with digital callipers on the plaster models.

Evaluation of the CT scanogram for assessment of craniofacial morphology.

Objective: The purpose of this prospective laboratory study was to investigate the suitability of the computed tomography scanogram (CT) as compared with conventional (CC) or storage phosphor digital (SP) lateral cephalograms.

Materials And Methods: Twenty intact, adult-sized, dry human skulls were used. Each skull was fixed in a custom-made plastic box and imaged in each of the three radiographic machines.

An alternative retainer design for cleft patients: the "aesthetic" retainer.

The objective of this report is to describe an original retainer design for retention following orthodontic treatment in cleft lip and palate patients in order to improve the aesthetics of anterior maxillary dentoalveolar cleft defects. The technique incorporates features of both traditional and modern retainer design. The advantages of the technique and fabrication process are described.

Change of incisor inclination effects on points A and B.

Objective: To identify and evaluate changes in the cephalometric position of points A and B due to an incisal inclination change caused by orthodontic treatment.

Materials And Method: A total of 103 pairs of consecutive pretreatment and posttreatment lateral cephalographs that met the inclusion criteria were systematically collected from the departmental database and digitized using a customized software program (Gela). Repeatability analyses showed good reliability and no evidence of bias.

An in vitro study into the corrosion of intra-oral magnets in the presence of dental amalgam.

The aim of this investigation was to study the corrosion behaviour and products of uncoated neodymium-iron-boron magnets in the presence of dental amalgam. Microcosm plaques were grown on discs of neodymium-iron-boron magnets or amalgam in a constant depth film fermentor. The biofilms were supplied with artificial saliva and growth was determined by viable counting.

Advances in orthodontics.

There has been tremendous progress in orthodontics since Edward Angle first popularised the fixed orthodontic appliance at the turn of the century. Recent years have seen an increased demand for orthodontic treatment from both adolescents and adults and, in addition, patient and clinician expectations of treatment outcomes continue to rise. A desire for more aesthetic materials has resulted in both smaller and 'tooth-coloured' appliances.
