Oral health-related quality of life following dental treatment under general anaesthesia for early childhood caries - a UK-based study.

Objective To assess parental reports of changes in oral health-related quality of life (OHRQoL) of young children in the UK with early childhood caries (ECC) following dental treatment under general anaesthesia (DGA). To compare the impact of oral rehabilitation (OR) and extraction-only (Exo) treatment approaches on this. Methods Data were collected using the proxy reported components of the Child Oral Health-Related Quality of Life (COHRQoL®) questionnaire: the Parent-Caregivers Perceptions questionnaire (P-CPQ) and Family Impact Scale (FIS), from a convenience sample of parents of children receiving DGA at a UK Paediatric Dental Department. Mean scores and prevalence impacts were compared pre- and postoperatively with mean change score and effect sizes calculations. Results Seventy-eight parents were recruited (51 children undergoing OR, 27 Exo) with 6 lost to follow-up (92.3%). Following treatment, changes in mean P-CPQ and FIS scores were statistically significant (P < 0.0001) with medium to large effect sizes (0.45–1.39). The differences in change scores between the two treatment approaches were not statistically different. Conclusion DGA for young children with early childhood caries resulted in substantial improvements in parent's ratings of their child's OHRQoL and of the impact on their families. Larger cohort studies are needed to validate these preliminary findings

Relative Acceleration Noise Mitigation for Nanocrystal Matter-wave Interferometry: Application to Entangling Masses via Quantum Gravity

Matter wave interferometers with large momentum transfers, irrespective of specific implementations, will face a universal dephasing due to relative accelerations between the interferometric mass and the associated apparatus. Here we propose a solution that works even without actively tracking the relative accelerations: putting both the interfering mass and its associated apparatus in a freely falling capsule, so that the strongest inertial noise components vanish due to the equivalence principle. In this setting, we investigate two of the most important remaining noise sources: (a) the non-inertial jitter of the experimental setup and (b) the gravity-gradient noise. We show that the former can be reduced below desired values by appropriate pressures and temperatures, while the latter can be fully mitigated in a controlled environment. We finally apply the analysis to a recent proposal for testing the quantum nature of gravity [S. Bose et. al. Phys. Rev. Lett 119, 240401 (2017)] through the entanglement of two masses undergoing interferometry. We show that the relevant entanglement witnessing is feasible with achievable levels of relative acceleration noise

Clinical, individual and environmental factors related to children’s health-related quality of life following treatment under general anaesthetic for dental caries : a path analysis

Objective To examine the impact of clinical, individual, and environmental factors on children’s oral health-related quality of life (OHRQoL) and overall health-related quality of life (HRQoL) following dental caries management under general anaesthetic (GA). Methods Participants comprised 5- to 16-year-old children who were referred to a British Dental Hospital, for the management of their dental caries under GA. The Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) and the Child Health Utility 9D (CHU9D) were used to assess child-reported OHRQoL and HRQoL, respectively, at baseline and 3-months follow up. A theoretical conceptual model, based on the Wilson and Cleary model of HRQOL, was evaluated using path analysis to explore indirect and direct relationships of the clinical, individual, and environmental variables on the quality of life outcomes following treatment. Results 85 children completed the study. Path analyses revealed that 47% of the variance in OHRQoL scores was accounted for by the variables in the model. There were significant relationships between change in OHRQoL score and treatment type [extraction only vs. combination care (β = 1.41, p = 0.07)] and number of extractions (β = 0.46, p < 0.001). A higher number of tooth extractions was associated with poorer OHRQoL and HRQoL following treatment. Conclusions Treatment type, via number of extractions, may significantly impact on child OHRQoL and HRQoL following treatment under GA. However, to identify any other factors, that might affect these key outcomes, further enquiry is warranted with a bigger sample

A qualitative study of barriers and facilitators to the implementation of a pilot school-based, toothbrushing programme

Background While supervised toothbrushing programmes have been established in many countries of the world, little is known about different perspectives on their implementation. The aim of the study was to explore stakeholders' barriers and facilitators to implementation of a school-based toothbrushing programme in Taiwan. Methods Focus groups and interviews were used to explore the views of elementary school students, teachers, staff, and nurses in a piloted school-based toothbrushing programme. The topic guides were developed according to the Theoretical Domains Framework (TDF) to cover the behavioural factors systematically and comprehensively. Data were analysed with content analysis. Results Overall, 36 students, 29 teachers/staff, and five school nurses (N = 65) were included. The overarching theme was the importance of habit formation for both staff and children to ensure that toothbrushing as part of the programme was embedded into the school schedule and routine. While children did not necessarily appear to retain the dental knowledge which was taught in the programme, the provision of fluoride toothpaste and toothbrush for their use in schools allowing teachers and staff to choose the timing of the brushing and engaging classmates to supervise each other were found to be key factors. Conclusions Implementing a school-based toothbrushing programme with the support of staff and active engagement of children can help children to develop a toothbrushing habit. Classmate-supervised toothbrushing may reduce the burden on teachers and staff to implement the programme

Oral clinical status and oral health-related quality of life: is socioeconomic position a mediator or a moderator?

AIM: To evaluate whether socioeconomic position exerts a mediating and/or moderating effect on the association between oral clinical measures and oral health-related quality of life (OHRQoL) in adolescents. MATERIALS AND METHODS: The study analysed data on 5,445 adolescents aged 15-19 years from the Brazilian Oral Health Survey (SBBrasil Project). The numbers of decayed and missing teeth, number of sextants with gingivitis and malocclusion were assessed through oral clinical examinations. Participant's age, sex, OHRQoL and socioeconomic position were also collected. Monthly family income was used to indicate the participant's socioeconomic position, and OHRQoL was assessed using the Oral Impacts on Daily Performance. Moderation was tested using Poisson regression models. Structural equation modelling and Sobel's test assessed the mediation effects. RESULTS: Oral clinical measures, OHRQoL and socioeconomic position were significantly correlated (P < 0.001). The moderator effect of socioeconomic position on the association between all oral clinical measures and OHRQoL was observed. The impact of all oral clinical conditions on adolescents' OHRQoL was lower in the low-family-income groups compared with those with a better income. Socioeconomic position partially mediated the relationship between the four oral clinical measures and OHRQoL. Sobel's test confirmed these findings (P < 0.001). CONCLUSIONS: The findings suggest the importance of socioeconomic position as a moderator and mediator factor between oral clinical measures and OHRQoL. Disadvantaged adolescents are likely to experience poor OHRQoL due to oral conditions. The reduction of the impact of oral conditions on quality of life in adolescents may be enhanced by addressing social inequalities related to oral health

It’s part of my life: engaging university and community to enhance science and mathematics education - final report, March 2017

This project is designed to improve mathematics and science teaching in Australian schools by engaging pre-service teachers with the mathematics and science that underpins everyday life in Australian regional communities. The project draws together the strengths of university mathematicians, scientists, and specialist educators to enhance the higher education mathematics and science education curriculum framework by grounding it in the practical contexts that are an integral part of our daily lives. In so doing, 'It's part of my life' addresses two critical issues in mathematics and science education: lack of teacher confidence, and lack of student interest. Along with a flexible and adaptive, scalable model for embedding real-world contexts and related teaching strategies into curriculum, project outcomes include an open educational resource of evaluated and documented real-life scenarios for inclusion in curriculum across all educational levels, tools for evaluating new scenarios, and increased networking amongst university researchers, specialist educators and members of the wider community

Facilitators for increasing dental attendance of people from vulnerable groups: a rapid review of evidence relevant to the UK

Objective To rapidly review facilitators of access for vulnerable groups and to evaluate their effectiveness. Methods Data sources: MEDLINE via Ovid. Publications in English from 2000. Data selection: Research involving ‘vulnerable groups' relevant to UK health systems, with a primary outcome of increasing attendance. Data extraction: One author extracted and tabulated data. These were audited by a second author. Data synthesis: A narrative synthesis was produced. Results Data from 31 studies were available for ten vulnerable groups: people with learning, physical or sensory disabilities (n = 8); people experiencing homelessness (n = 6); prisoners (n = 4); asylum-seekers and refugees (n = 3); people living in socioeconomically deprived areas (n = 3); people with severe mental health conditions (n = 2); vulnerable children (n = 2); dependent older people (n = 1); Gypsy, Roma or Traveller groups (n = 1); and people with drug dependency (n = 1). Many facilitators involved organisational reform and more integration of health, social and other services. Other facilitators included: modification of premises; team development and skill-mix use; and awareness of needs and flexible services to meet them. Few studies evaluated effectiveness. Conclusion Although facilitators for access for vulnerable groups have been proposed, there is little evidence to support or refute their effectiveness. Efforts are needed to promote access for vulnerable groups in the UK with evaluation plans embedded

Child caries management: A randomized controlled trial in dental practice

This multicenter 3-arm, parallel-group, patient-randomized controlled trial compared clinical effectiveness of 3 treatment strategies over 3 y for managing dental caries in primary teeth in UK primary dental care. Participants aged 3 to 7 y with at least 1 primary molar with dentinal carious lesion were randomized across 3 arms (1:1:1 via centrally administered system with variable-length random permuted blocks): C+P, conventional carious lesion management (complete carious tooth tissue removal and restoration placement) with prevention; B+P, biological management (sealing in carious tooth tissue restoratively) with prevention; and PA, prevention alone (diet, plaque removal, fluorides, and fissure sealants). Parents, children, and dentists were not blind to allocated arm. Co–primary outcomes were 1) the proportion of participants with at least 1 episode of dental pain and/or infection and 2) the number of episodes of dental pain and/or infection during follow-up (minimum, 23 mo). In sum, 1,144 participants were randomized (C+P, n = 386; B+P, n = 381; PA, n = 377) by 72 general dental practitioners, of whom 1,058 (C+P, n = 352; B+P, n = 352; PA, n = 354) attended at least 1 study visit and were included in the primary analysis. The median follow-up was 33.8 mo (interquartile range, 23.8 to 36.7). Proportions of participants with at least 1 episode of dental pain and/or infection were as follows: C+P, 42%; B+P, 40%; PA, 45%. There was no evidence of a difference in incidence of dental pain and/or infection when B+P (adjusted risk difference [97.5% CI]: −2% [−10% to 6%]) or PA (4% [−4% to 12%]) was compared with C+P. The mean (SD) number of episodes of dental pain and/or infection were as follows: C+P, 0.62 (0.95); B+P, 0.58 (0.87); and PA, 0.72 (0.98). Superiority could not be concluded for number of episodes between B+P (adjusted incident rate ratio (97.5% CI): 0.95 [0.75 to 1.21]) or PA (1.18 [0.94 to 1.48]) and C+P. In conclusion, there was no evidence of a difference among the 3 treatment approaches for incidence or number of episodes of dental pain and/or infection experienced by these participants with high caries risk and established disease (trial registration: ISRCTN77044005)
