#1
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...

Suhaym Mubeen, Jadbinder Seehra
Ankylosis, mechanical and primary failure of eruption of molar teeth are rare and often difficult to distinguish between. All may have significant repercussions on the occlusion and successful management may involve invasive procedures. We present a case where an initial presentation characteristic of mechanical failure of eruption (ankylosis) of a first permanent molar tooth was excluded following a period of monitoring. Subsequent relief of crowding using a removable and then sectional fixed orthodontic appliance allowed spontaneous eruption of the tooth obviating the need for surgical intervention...

OBJECTIVE: The primary aim was to determine what, if any, relationships exist between communication and quality of life in patients receiving orthognathic treatment since this has not been explored. A secondary aim was to compare the Quality of Life (QoL) of a pre-treatment sample with those at 2 years post-surgery. DESIGN: A cross-sectional questionnaire method was used. SETTING: Outpatient clinics providing orthognathic treatment at four UK hospital sites...

OBJECTIVE: The principal aim was to establish whether dental appearance affects employment prospects, and if so a secondary aim was to ascertain whether there is a difference between public-facing and non-public-facing jobs. DESIGN: A prospective cross-sectional experimental analogue study. PARTICIPANTS: Ninety undergraduates studying at London Metropolitan University School of Business. METHODS: Vignettes comprising curriculum vitae (CV) with a single photograph of the applicant attached formed the experimental manipulation...

Aslam Alkadhimi, Ebrahim A Al-Awadhi
INTRODUCTION: In recent years, extensive research has introduced novel ways of reinforcing orthodontic anchorage using a variety of devices temporarily anchored in bone (miniscrews). Currently, there are numerous manufacturers with different miniscrew designs on the market. AIMS: The aim of this paper is to discuss the key design features of different miniscrew systems on the market. Furthermore, to present clinical selection criteria of miniscrews in different settings taking into account the determinant factors...

The purpose of this paper is to present and discuss a simple and low-cost clinical approach to correct an asymmetric skeletal Class III combined to an extensive dental open bite that significantly compromised the occlusal function and smile aesthetics of an adult male patient. The patient did not accept the idealistic surgical-orthodontic treatment option, neither the use of temporary anchorage devices to facilitate the camouflage of the asymmetrical skeletal Class III/open bite. Therefore, a very simple and inexpensive biomechanical approach using sliding jigs in the mandibular arch was implemented as the compensatory treatment of the malocclusion...

OBJECTIVE: To determine the reproducibility of Index of Orthognathic Functional Treatment Need (IOFTN) scores derived from plaster casts and their three-dimensional (3D) digital equivalents. DESIGN: Pilot study, prospective analytical. SETTING: UK hospital orthodontic department. PARTICIPANTS: Thirty casts and their digital equivalents, representing the pre-treatment malocclusions of patients requiring orthodontic-orthognathic surgical treatment, were scored by four clinicians using IOFTN...

Haematemesis is a worrying sign, generally related to acute upper gastrointestinal bleeding and potentially life-threatening condition. We present a case of a 15-year-old Caucasian girl who was belatedly diagnosed with oral bleeding because it was not related to the most common aetiologic factors. In fact, she was undergoing orthodontic treatment with a Nance palatal arch, an appliance used to reinforce anchorage during teeth movements. In her case haematemesis was a sign of inflammation and necrosis occurring in the palatal mucosa, under the acrylic button of palatal arch...

AIMS: The purpose of this study was to evaluate the efficacy of orthodontic bonding systems containing different antimicrobial agents, as well as the influence of antimicrobial agent incorporation in the bonding properties of these materials. METHODS: Eight databases were searched: PubMed (Medline), Web of Science, Scopus, Lilacs, Ibecs, BBO, Scielo and Google Scholar. Any study that evaluated antimicrobial activity in experimental or commercial orthodontic bonding systems was included...
