ABSTRACT

OBJECTIVE: To evaluate the effectiveness of bone anchored maxillary protraction (BAMP) in the management of class III skeletal malocclusion in children aged 11-14 years compared with an untreated control group in terms of perceived need for orthognathic surgery, skeletal and dental change, and psychological impact. DESIGN: A multicentre two-armed parallel randomised controlled trial. SETTING: Six UK hospital orthodontic units. METHODS: A total of 57 patients were randomly allocated into either the BAMP group (BAMPG) (n = 28) or a no treatment control group (CG) (n = 29). OUTCOMES: Data collection occurred at registration (DC1),18 months (DC2) and 3 years (DC3), where skeletal and dental changes were measured from lateral cephalograms and study models. Oral Aesthetic Subjective Impact Score (OASIS) and Oral Quality of Life (OHQOL) questionnaires were used to assess the psychological impact of treatment. RESULTS: The mean age was 12.9 ± 0.7 years and 12.6 ± 0.9 years in the BAMPG and CG, respectively. At DC2, the BAMPG achieved a class III ANB improvement of +0.6° compared with -0.7° in the CG (P = 0.004). The overjet improvement was +1.4 mm for the BAMPG and -0.2 mm for the CG (P = 0.002). There was no evidence of any other group differences for the other skeletal or dental cephalometric outcomes (P > 0.05) or the questionnaire data (OASIS P = 0.10, OHQOL P = 0.75). At DC2, the 18-month follow-up, 22% of the BAMPG achieved a positive overjet. At the 3-year follow-up (DC3), fewer patients in the BAMPG were perceived to need orthognathic surgery (48%) compared with 75% of patients in the CG (P = 0.04), with an odds ratio of 0.31 (95% confidence interval = 0.10-0.95). CONCLUSION: The BAMP technique did not show any social or psychological benefits; however, the skeletal class III improvement in ANB and the overjet change were sufficient to reduce the perceived need for orthognathic surgery by 27% compared with the CG.

ABSTRACT

The Dental gold guide was originally developed in 2009 by the UK Committee of Postgraduate Dental Deans and Directors as a reference document for those undertaking specialist training within the UK. A similar document was later produced for dental core training in 2013, called the Silver guide. The documents act as a framework for training and outline the regulations and assessment processes. The latest edition of the Dental gold guide, published in September 2021, combines the original gold and silver guide documents, making it applicable to both speciality trainees and dental core trainees.This review article summarises this most recent version of the guide, covering all areas of speciality and dental core training, including the responsibilities of those involved in training and recruitment and arrangements for less than full-time training, as well as a summary of the review of competency progression process. It is hoped to provide a user-friendly reference for both trainees and trainers within the UK.

ABSTRACT

As one of the US Department of Agriculture-Agricultural Research Service flagship databases, GrainGenes (https://wheat.pw.usda.gov) serves the data and community needs of globally distributed small grains researchers for the genetic improvement of the Triticeae family and Avena species that include wheat, barley, rye and oat. GrainGenes accomplishes its mission by continually enriching its cross-linked data content following the findable, accessible, interoperable and reusable principles, enhancing and maintaining an intuitive web interface, creating tools to enable easy data access and establishing data connections within and between GrainGenes and other biological databases to facilitate knowledge discovery. GrainGenes operates within the biological database community, collaborates with curators and genome sequencing groups and contributes to the AgBioData Consortium and the International Wheat Initiative through the Wheat Information System (WheatIS). Interactive and linked content is paramount for successful biological databases and GrainGenes now has 2917 manually curated gene records, including 289 genes and 254 alleles from the Wheat Gene Catalogue (WGC). There are >4.8 million gene models in 51 genome browser assemblies, 6273 quantitative trait loci and >1.4 million genetic loci on 4756 genetic and physical maps contained within 443 mapping sets, complete with standardized metadata. Most notably, 50 new genome browsers that include outputs from the Wheat and Barley PanGenome projects have been created. We provide an example of an expression quantitative trait loci track on the International Wheat Genome Sequencing Consortium Chinese Spring wheat browser to demonstrate how genome browser tracks can be adapted for different data types. To help users benefit more from its data, GrainGenes created four tutorials available on YouTube. GrainGenes is executing its vision of service by continuously responding to the needs of the global small grains community by creating a centralized, long-term, interconnected data repository.

ABSTRACT

Modern breeding methods integrate next-generation sequencing and phenomics to identify plants with the best characteristics and greatest genetic merit for use as parents in subsequent breeding cycles to ultimately create improved cultivars able to sustain high adoption rates by farmers. This data-driven approach hinges on strong foundations in data management, quality control, and analytics. Of crucial importance is a central database able to (1) track breeding materials, (2) store experimental evaluations, (3) record phenotypic measurements using consistent ontologies, (4) store genotypic information, and (5) implement algorithms for analysis, prediction, and selection decisions. Because of the complexity of the breeding process, breeding databases also tend to be complex, difficult, and expensive to implement and maintain. Here, we present a breeding database system, Breedbase (https://breedbase.org/, last accessed 4/18/2022). Originally initiated as Cassavabase (https://cassavabase.org/, last accessed 4/18/2022) with the NextGen Cassava project (https://www.nextgencassava.org/, last accessed 4/18/2022), and later developed into a crop-agnostic system, it is presently used by dozens of different crops and projects. The system is web based and is available as open source software. It is available on GitHub (https://github.com/solgenomics/, last accessed 4/18/2022) and packaged in a Docker image for deployment (https://hub.docker.com/u/breedbase, last accessed 4/18/2022). The Breedbase system enables breeding programs to better manage and leverage their data for decision making within a fully integrated digital ecosystem.

ABSTRACT

This paper does not set out to describe the reasons why a new concept of dental care should be deemed as acceptable and recognised as mainstream. Rather, the starting point of this paper is the belief that some dentists who are increasing the overall vertical dimension for worn dentition patients are not using the protocols of the traditional 're-organised approach'. If adhesive direct restorations are used, there seems to be anecdotal indication that despite not restoring in the terminal hinge axis, it can have a successful outcome.So, while not criticising this approach simply because it does not follow orthodoxy, the paper has two objectives. It hopes to stimulate some debate and research on this subject. Furthermore, by suggesting some parameters for what might be considered a new approach, it aims to improve patient outcome.

ABSTRACT

Patient consent is a principal issue in healthcare. The well-publicised case between Montgomery versus Lanarkshire has highlighted the importance of consent to include a discussion of all relevant treatment risks. Within orthodontics, there are published guidelines from the profession's governing body as to the common risks associated with treatment. Within hospitals and practices, the consent process is usually determined by set policies, which may be devised by non-clinical teams. Clinicians are well positioned to critique these processes and their input into such policies may be beneficial. A two-cycle, multi-centre audit was completed to assess the consistency of consent forms in two orthodontic departments. The results from the first cycle initiated the implementation of changes to hospital policy, in order to produce a new procedure-specific consent form for orthodontic treatment. Results from the second cycle of the audit, together with clinician feedback, showed that the new forms allowed for a more streamlined approach to the consent process and ensures patients are fully informed of all aspects of their personal treatment.

ABSTRACT

The aim of this paper is to inform the reader of the main principles considered in the management of mild hypodontia involving the absence of one or more maxillary lateral incisors. With increasing demand and limited resources of hospital dental services, general dental practitioners (GDPs) are required to actively participate in the restorative management of mild hypodontia cases. The objectives of this article are to discuss the arguments for and against space opening versus space closure and to highlight key points to consider in treatment planning. The paper discusses advantageous scenarios for both space opening and space closing cases, with the aim of providing the reader with some basic concepts to apply to cases in general practice. Included in the paper is guidance for practitioners on the diagnosis of a missing maxillary incisor via the use of a flow chart and table. It is hoped that this paper will support and enhance the care delivered by GDPs in the restorative management of mild hypodontia patients.

ABSTRACT

BACKGROUND: Orthodontic therapists (OTs) are the most recent addition to the orthodontic clinical team. The General Dental Council (GDC) and the British Orthodontic Society have formulated guidance and guidelines relating to their scope of practice and level of supervision, however there has been no contemporary UK-based research investigating practice and supervision of OTs. The aim of this study was to investigate the scope of practice and level of supervision of OTs working in the UK. METHOD: Ethical approval was received from the University of Manchester Research Ethics Committee. An anonymous postal questionnaire was dispatched using postal details acquired through the British Orthodontic Societies mailing list. Three mailings of the questionnaire were conducted. RESULTS: A 74% response rate was achieved. OTs routinely conducted 16 of the 20 procedures from their scope of practice. Uncommon procedures included fitting headgear (24%), lingual appliances (27%), inserting or removing temporary anchorage devices (20%), and taking facebow record (18%). A total of 62% of OTs took patient consent for treatment. 59% were supervised through a written prescription with no direct supervision. OTs were directly supervised for only a quarter of their clinical practice. Orthodontists viewing frequency for OTs varied significantly, and was found to be the following: every 2-4 visits (36%), every other visit (35%), and every visit (26%). CONCLUSIONS: OTs mostly carried out the scope of practice as permitted by the GDC. Procedures uncommon to routine orthodontic practice were also uncommon to Orthodontic therapist clinical practice. OTs work mostly through written prescription with no direct supervision.

ABSTRACT

OBJECTIVE: Since the introduction of orthodontic therapists (OTs), there has been little research on the scope of practice and the level of supervision they receive. This study investigates how OTs are being utilised and supervised, and how this compares with current recommendations. METHODS AND PARTICIPANTS: A postal cross-sectional survey was mailed to all UK General Dental Council (GDC) registered specialist orthodontists. RESULTS: A 59.7% response rate (747) was achieved. 52% of the respondents reported they worked with/employed an OT. The majority of orthodontists worked with an OT in primary care (67%) seeing predominantly NHS (56%) patients and performed a wide range of duties. Orthodontists reported a perceived increase in clinical output (74%) and time available for treatment planning (61%). The majority (85%) of orthodontists indicated they provide a written prescription for the OT. Forty-two per cent reported the prescription did not contain the required information as stipulated by the GDC. CONCLUSIONS: OTs are valued members of the orthodontic team, improving productivity and allowing orthodontists more time for treatment planning. The majority of orthodontists appeared to be working to the BOS and GDC recommendations, with greater awareness needed regarding the provision of a written treatment prescription.

ABSTRACT

The correction of severe dentofacial discrepancies involving a combination of orthodontic and surgical therapies (termed 'orthognathic treatment') is commonplace. There is an abundance of evidence within this field but it is often inconsistent. This article is an evidence-based overview of such treatments and is aimed at the general dental practitioner. It will cover: the timing of treatment; the indications and risks associated with different surgical osteotomies; the magnitude of surgical movements that can be achieved with these procedures; and the importance of mandibular autorotation when planning treatment. Orthognathic treatment is considered to be the gold standard for comprehensive correction of severe dentofacial discrepancies. It is undertaken by a multidisciplinary team of clinicians involving, but not exclusive to, consultants in orthodontics and oral and maxillofacial surgery in secondary and tertiary medical centres throughout the United Kingdom. Clinical relevance: It is imperative that general dental practitioners have a good understanding of orthognathic treatment in order to recognize when such treatments are indicated, to inform the patient of possible treatment modalities and to be able to discuss associated risks in order to make appropriate referrals. Since treatment timing and magnitude of surgical movements have a profound effect on stability of the treatment result, these must be carefully considered by all clinicians involved in patient care to minimize relapse potential.

ABSTRACT

The clinical problem of how best to manage a dilacerated, impacted maxillary central incisor will only be encountered rarely. The treatment aim should be to achieve results that are indistinguishable from normal appearance in a way that is appropriate for the patient. This article discusses the incidence of dilacerations in maxillary incisors and describes the treatment approaches available − orthodontic alignment or surgical removal and management of the resulting space, considering orthodontic repositioning, autotransplantation and various prosthetic replacements. Treatment indications, advantages and disadvantages, restorative and surgical implications, as well as the evidence-base relating to the various treatment modalities will be presented, along with clinical case examples. Clinical relevance: This paper discusses a problem that, if not managed appropriately, can lead to poor results for the patient. Even for practitioners who may not undertake the treatment mentioned, it will enable them to have more in-depth discussion with their patients should the situation arise.
