Impact of the COVID-19 pandemic on orthognathic patients: What have we learned?

Due to the COVID-19 pandemic orthognathic surgery was suspended in the UK. The effect this had on patients, to date, is unknown. A multi-centre, cross-sectional survey was conducted in the UK to investigate the health-related impact on patients on the orthognathic surgery pathway, including those on the waiting list for surgery.

Five-year prospective fistula audit in a single center. TIG training negates consultant learning curve, but surgeons should beware the mid-range palatal defect.

The aim of primary palatoplasty is to achieve optimum speech with minimal morbidity. Symptomatic fistulae are well-recognised complications of palatoplasty and may require additional surgical intervention, increasing the burden of care. Our aims were to better understand fistula experience in our unit and compare fistula rates between an established consultant and a newly appointed training interface group (TIG) trained consultant.

Orthognathic patient perception of 3D facial soft tissue prediction planning.

The primary aim of this study was to explore patients' perceptions regarding the impact of 3D prediction planning (3D PP) of facial soft tissue changes following orthognathic surgery. The study was carried out on 30 patients who were shown photorealistic 3D soft tissue prediction planning before undergoing orthognathic surgery to demonstrate the expected facial changes. Distraction osteogenesis and cleft deformities were excluded from the study before consenting to surgery.

The impact of wrong-site surgery on dental undergraduate teaching: a survey of UK dental schools.

Introduction: Patient safety within dental education is paramount. Wrong-site surgery (WSS) tooth extraction is not uncommon and is a significant never event (NE) in dentistry. This study aimed to explore dental schools' undergraduate experience of NEs, safety interventions implemented and the impact on student experience.

is a bacterium which normally resides within the oral microflora. A female infant was born by emergency caesarean section owing to fetal distress with a gestational age of 38 weeks, a birthweight of 2250 g and a temperature of 36.5°C.

The Validation of an Innovative Method for 3D Capture and Analysis of the Nasolabial Region in Cleft Cases.

Objective: To validate a newly developed method for capturing 3-dimensional (3D) images of the nasolabial region for assessing upper lip scarring and asymmetry in surgically managed unilateral cleft lip and palate (UCLP) cases.

Design: Validation study, single cohort.

Materials And Methods: Eighteen surgically managed UCLP cases were recruited, the nasolabial region of each face was scanned using an intraoral scanner (IOS) to produce 3D images.

How lay health workers tailor in effective health behaviour change interventions: a protocol for a systematic review.

Background: Lay health workers (LHWs) are utilised as a channel of delivery in many health interventions. While they have no formal professional training related to their role, they utilise their connections with the target group or community in order to reach individuals who would not normally readily engage with health services. Lay health worker programmes are often based on psychological theories of behaviour change that point to 'tailoring to individuals' needs or characteristics' as key to success.

Biomaterials in the Reconstruction of the Oral and Maxillofacial Region.

Reconstruction of maxillofacial bones has proven to be complex due to the aesthetic requirements and functional demands of the jaw. Although autogenous bone grafts and a wide range of biomaterials are routinely used for facial bone reconstruction, these methods are associated with a number of drawbacks, including the limited availability of autogenous grafts and the morbidity associated with bone graft harvesting, whilst biomaterials are also linked with a high failure rate. These limitations have inspired the search for innovative techniques for bone bioengineering and the development of more reliable biomaterials.

Evaluation of an interactive multi-media device for delivering information on Le Fort I osteotomy.

This study was carried out on volunteers to evaluate a newly developed interactive software package aimed at informing prospective Le Fort I osteotomy patients regarding the surgical technique and possible complications. The aim of the study was to compare two methods of information delivery; a multi-media tablet device delivering both graphic and verbal information, and an audio device delivering essentially the same information in verbal form only. The null hypothesis was that there would be no difference between the efficiencies of the two methods.

Case report: Cone-beam ct imaging in the management of a double tooth.

Background: The diagnosis and management strategies of double teeth have largely relied on clinical examination and conventional radiographic findings. Cone-Beam Computed Tomography (Cone-beam CT) was developed in the late 1990's and, therefore, is a relatively recent addition to the imaging armamentarium for use in Maxillofacial Radiology. There have been no publications in the dental literature demonstrating the use of Cone-beam CT or 3D stereolithography in the diagnosis and surgical planning of the management of double teeth.

Care home staff knowledge of oral care compared to best practice: a West of Scotland pilot study.

Aim: To evaluate care home (N) staff knowledge of oral care provision for dependent older people in comparison to guidelines from NHS Quality Improvement Scotland (NHSQIS). This pilot study also aimed to identify barriers to delivering oral care and determine if oral health educator (OHE) training had an effect upon staff knowledge of oral care delivery.

Setting: This cross-sectional analytic investigation was undertaken within the Greater Glasgow & Clyde area between 2005 and 2007.

Nurse-delivered brief interventions for hazardous drinkers with alcohol-related facial trauma: a prospective randomised controlled trial.

Aims: To assess the impact of two methods of brief nurse-delivered brief interventions in reducing drinking variables in hazardous drinkers with alcohol-related facial injuries.

Methods: A randomised controlled trial of two brief interventions involving hazardous drinkers with facial trauma in three Oral and Maxillofacial Surgery outpatient clinics in the West of Scotland; 194 patients were recruited and randomised to have either a nurse-led brief motivational intervention (intervention group) or a leaflet about alcohol misuse (control group). Patients were followed up at 3 and 12 months after the intervention and drinking variables reassessed.

Dental caries in 5-year-old children attending multi-ethnic schools in Greater Glasgow--the impact of ethnic background and levels of deprivation.

Objective: To examine levels of dental caries of 5-year-olds attending multi-ethnic schools in Greater Glasgow and to explore the effects of deprived backgrounds and ethnic identity on their dental health.

Design: Between October 2001 and February 2002 a cross-sectional dental epidemiology survey of a sample of 721 5-year-olds was undertaken in schools having at least 25 per cent of pupils from black or minority ethnic groups. Background data on participating children were obtained from school records, including: ethnic origin, mothers' ability to speak English, religion, and demographics.

Treatment of aesthetic problems in paediatric dentistry.

Aesthetic problems in childhood and adolescence can have a significant effect on psychosocial development and interaction with peers. Abnormalities of shape, size, colour and structure of the whole or part of the anterior dentition of children can lead to such problems. This article outlines the most appropriate options for the clinical management of different aetiological categories of aesthetic problems, and develops a hierarchy of intervention that should be pursued in a logical order until a satisfactory cosmetic outcome is achieved.

Incidence of oral and oropharyngeal cancer in United Kingdom (1990-1999) -- recent trends and regional variation.

This study aimed to determine whether the incidence of oral cancer is continuing to rise in the UK and if this varies geographically. A descriptive epidemiological study of oral cancer incidence in 12 UK cancer registries (1990-1999) was undertaken. Poisson regression models were employed to assess trends.

Prevalence of dental fluorosis in children from non-water-fluoridated Halmstad, Sweden: fluoride toothpaste use in infancy.

Objectives: To determine the prevalence and severity of dental fluorosis in children aged 7-9 years from non-water-fluoridated Halmstad, Sweden, and to relate the results to their reported fluoride exposure history during infancy.

Material And Methods: In Spring 2002, a questionnaire distributed to a cluster random sample of 1039 parents enquired into their child's early oral health behaviors and included a "photographic toothpaste menu". The permanent upper anterior teeth (13-23) were examined clinically (+10% repeats) using a modified Thylstrup-Fejerskov Index.

Reducing variability and choosing ideal subjects for experimental gingivitis studies.

Introduction: This study was undertaken to test the hypothesis that male, non-smokers, aged 25-50 years, with a proven track record of developing gingivitis would provide suitable subjects for experimental gingivitis studies because the inter-subject variation would be greatly reduced.

Materials And Methods: Subjects were required to be men aged between 25 and 50 years, in good general health with at least four sound teeth in one posterior quadrant of the mandible. Subjects who were smokers, taking antibiotics, anti-inflammatory drugs or had any other medical, surgical or social condition making participation in the study inadvisable, were excluded.

Are facial expressions reproducible?

Objectives: To determine the extent of reproducibility of five facial expressions.

Design: Thirty healthy Caucasian volunteers (15 males, 15 females) aged 21 to 30 years had 20 landmarks highlighted on the face with a fine eyeliner pencil. Subjects were asked to perform a sequence of five facial expressions that were captured by a three-dimensional camera system.

Fluoride release from orthodontic band cements-a comparison of two in vitro models.

Objectives: To compare, in vitro, the fluoride release from a conventional glass ionomer cement (Ketac-Cem), a resin-modified glass ionomer cement (3M-Multicure) and a polyacid modified composite (Ultra Band-Lok) using a banded tooth model and a disc model with the same mean cement weight.

Methods: Forty pairs of caries-free third molars were collected and divided into two groups, each of 20 teeth. One tooth from each pair was banded with Ketac-Cem and the other with Ultra Band-Lok or 3M-Multicure; the average band size for each cement group was the same.

Oral cancer: prevention and detection in primary dental healthcare.

The incidence of oral cancer is rising in the UK. Mortality from the disease remains high and survival has not improved significantly in the last 30 years. The primary dental health team has an integral role in the delivery of oral health promotion and prevention advice and in the early detection of oral malignancy and potentially malignant lesions.

Humoral immune response in early-onset periodontitis: influence of smoking.

Sixty-five patients with generalised early-onset periodontitis (G-EOP) (age range 16-42 years, 32 smokers and 33 non-smokers) were assessed for antibody titres and avidity to a panel of five suspected periodontal pathogens (Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Prevotella intermedia, Treponema denticola and Bacteroides forsythus). Thirty-four of these patients were untreated (17 smokers and 17 non-smokers), and thirty-one were in the maintenance phase of periodontal therapy (15 smokers and 16 non-smokers). Previous studies have investigated the effect of smoking on IgG levels in periodontitis patients in the context of the more extensive periodontal destruction seen in smokers.
