OBJECTIVES: Tooth wear, additional to the physiologic alterations of the dentition, may occur during orthodontic treatment. The objective of the present review was to investigate systematically the literature relevant to its progression in patients having undergone comprehensive orthodontic treatment. DATA SOURCES: Search without restrictions in eight databases since inception and hand searching until October 2017 was performed. DATA SELECTION: Studies evaluating tooth wear immediately before and after the completion of orthodontic treatment with fixed appliance were evaluated independently and in duplicate...

#12
Sama Al-Junaid, Priti Acharya
Root resorption is a common but undesirable side-effect of orthodontic treatment. It is a well-recognised phenomenon largely associated with impacted or unerupted teeth and in most cases, is mild and does not affect longevity of the affected teeth. This case report of a medically fit and healthy Caucasian boy who was undergoing orthodontic treatment at the Eastman Dental Hospital, UCLH (EDH) for management of his severe hypodontia, presents an unusual incident of bilateral resorption of his maxillary first permanent molars by the unerupted second molars...

OBJECTIVES: To evaluate the efficiency and effectiveness of Orthodontic treatment in the National Health Service (NHS) hospitals in England and to identify factors that may be predictive of the duration of Orthodontic treatment and number of patients' visits. DESIGN: Retrospective service evaluation. SETTING: The orthodontic departments of two NHS hospitals. METHODS: The data were collected from the clinical notes, the hospital data base and the pre- and post-treatment study models of 70 patients who were treated with fixed appliances...

Body dysmorphic disorder (BDD) is a psychiatric disorder in which the individual has a disproportionate concern about a particular body part. With the increasing demand for aesthetic treatments, it is likely that individuals with BDD may present for orthodontic or combined orthodontic and orthognathic treatment. In this review, we shall outline the features of BDD and its prevalence, before discussing the best way for clinicians to identify and manage individuals with this disorder.

Paiboon Techalertpaisarn, Antheunis Versluis
OBJECTIVE: Intrusive forces on anterior brackets are preferable for avoiding overbite deepening. Reversing plain L-loops may create such advantageous force system during space closure. DESIGN: Force systems of reversed L-loops were compared with T-loops at three interbracket distances (IBD). SETTING: Computational study. METHODS: Using finite element analysis, loop response during simulated loop-pulling was determined for plain reversed L- and T-loop configurations at three IBDs and two sizes...

Natalie Ackuaku, Geetanjali Sharma
Premolar migration is an infrequent and unusual phenomenon. Although several cases of distal premolar migration have been reported in the literature, the management of these cases is often challenging and to date, there are no agreed guidelines regarding best practice. This report describes two cases of distal migration of a lower second permanent premolar with sequential panoramic imaging mapping the progress of the teeth as they migrated distally. Cone Beam Computerised Tomography was subsequently used in one case to locate the migrated premolars' precise position...

Acrylate allergies have been reported in dental professionals as a result of repeat exposure to various acrylate monomers and in dental patients with removable prostheses or longstanding composite restorations. To date, there is only one report of an allergic reaction in a young patient from small volumes of resin-based orthodontic adhesive. This case report demonstrates a recent case of gingival inflammation and lip oedema attributed to an acrylate allergy arising from the composite adhesive used with fixed appliances...

OBJECTIVE: The aim of this study was to evaluate the association between genetic polymorphisms in RANK, RANKL and OPG with maxillary and mandibular dimensions in humans. DESIGN: DNA extracted from saliva and the rs3826620, rs9594738 and rs2073618 polymorphisms in RANK, RANKL and OPG, respectively, were analysed by real-time PCR. Four linear measurements (Co-Gn, GoPg, Co-Go and PTM-A) from lateral cephalograms were examined for the evaluation of craniofacial measurements...
