RESUMO
BACKGROUND: The NHS has the target of reducing its carbon emission by 80% by 2032. Part of its strategy is using pharmaceuticals with a less harmful impact on the environment. Nitrous oxide is currently used widely within the NHS. Nitrous oxide, if released into the atmosphere, has a significant environmental impact. Methoxyflurane, delivered through the Penthrox 'green whistle' device, is a short-acting analgesic and is thought to have a smaller environmental impact compared with nitrous oxide. METHODS: Life cycle impact assessment (LCIA) of all products and processes involved in the manufacture and use of Penthrox, using data from the manufacturer, online sources and LCIA inventory Ecoinvent. These data were analysed in OpenLCA. Impact data were compared with existing data on nitrous oxide and morphine sulfate. RESULTS: This LCIA found that Penthrox has a climate change effect of 0.84 kg carbon dioxide equivalent (CO2e). Raw materials and the production process contributed to majority of the impact of Penthrox across all categories with raw materials accounting for 34.40% of the total climate change impact. Penthrox has a climate change impact of 117.7 times less CO2e compared with Entonox. 7 mg of 100 mg/100 mL of intravenous morphine sulfate had a climate change effect of 0.01 kg CO2e. CONCLUSIONS: This LCIA has shown that the overall 'cradle-to-grave' environmental impact of Penthrox device is better than nitrous oxide when looking specifically at climate change impact. The climate change impact for an equivalent dose of intravenous morphine was even lower. Switching to the use of inhaled methoxyflurane instead of using nitrous oxide in certain clinical situations could help the NHS to reach its carbon emission reduction target.

BACKGROUND: Environmental sustainability has been brought into the limelight due to the global climate crisis. This crisis is driven by human activities and even the healthcare sector is no exception. Within dentistry, orthodontics is a large global market; hence, the use of post-orthodontic retainers has a significant environmental footprint. The aim of this study was to determine the environmental sustainability of post-orthodontic retention using Hawley and Essix retainers. MATERIALS AND METHODS: A comparative life-cycle assessment (LCA) was carried out to compare the environmental impact of both retainers. All inputs and outputs were accounted for using the Ecoinvent database, v3.7.1, and openLCA software. Sixteen impact categories were used to determine their environmental burden. RESULTS: Of the 16 impact categories, the Hawley had a greater environmental burden than the Essix retainer in 12 categories. The Hawley's most significant contributors to its impact values are factory manufacturing and in-house production, with an average of 41.45% and 52.52%, respectively. For the Essix, the greatest contributor is factory manufacturing, with an average of 64.63%. However, when factoring in the lifespan of the retainers, the Essix would have a greater environmental impact than the Hawley retainer. LIMITATIONS: This study employed a comparative LCA. There were also assumptions made, but these were supported by research. CONCLUSIONS: On the basis of the evidence gathered in this study, Hawley retainers are more environmentally sustainable than Essix retainers. These results would better enable clinicians to factor in the environmental impact and make informed decisions on the choice of retainer type.

INTRODUCTION: This paper reports on the scholarship activity of the 'Sustainability in Dentistry' Special-interest Group (SiG), which met at the Association for Dental Education in Europe (ADEE) annual conference in Liverpool on 25 August 2023. The aim of this study was to (i) identify current teaching practices and approaches to embedding Environmental Sustainability (ES) in the curriculum in ADEE attendee schools and (ii) explore existing barriers/challenges to incorporating ES in dental education and consider potential solutions. METHODOLOGY: A mixed-methods approach was used to fulfil the aims of this study. A pre-workshop questionnaire was used to explore current teaching practices, challenges and drivers of embedding ES in the curriculum. An interactive workshop at the in-person meeting in Liverpool was used to propose key strategies to overcome the most frequent challenges to embedding ES in the curriculum. RESULTS: The majority of respondents (56%) reported that their institutions do not currently teach ES. Traditional didactic forms of teaching were mostly reported to teach ES in non-clinical environments, and a transition to more environmentally sustainable materials and instruments was the most popular response for clinical teaching. Key barriers to embedding ES in the curriculum were identified, including time constraints and the overloaded curriculum, a lack of expertise/knowledge to teach and lack of practical guidance to support educators, limited learning resources for staff and students and resistance from colleagues regarding the relevance of ES in dentistry. The special-interest group participants proposed strategies to overcome these challenges that centred around 14 themes. CONCLUSION: This paper reports recent scholarship activity by ADEE's 'Sustainability in Dentistry' SiG. Key strategies for overcoming the most common challenges to embedding ES in the curriculum are also discussed.
RESUMO
DATA SOURCES: Three electronic databases (Pubmed, Embase and the Cochrane Library) were searched in December 2022, and again for additional literature on 3-5th January 2023. Reference lists of relevant systematic reviews were hand searched for other eligible studies for inclusion. STUDY SELECTION: Randomised controlled clinical trials and controlled clinical trials conducted on children (aged ≤ 18 years), conducted between 1974-2022 and available in English, were eligible for inclusion. Studies were excluded if caries was not an outcome, the control group was not sufficient, they were lab-based studies or studies where xylitol delivery was not a sweet or chewing gum and where the xylitol product contained a component such as fluoride which may influence the outcomes. DATA EXTRACTION AND SYNTHESIS: Four calibrated reviewers independently screened titles and abstracts, and disagreements were resolved via group discussion. Preventative effect was determined by comparing the mean caries increment in the control and intervention groups, producing a preventative fraction. A total of 617 titles were initially screened for relevance. After duplicate removal, 268 abstracts were screened and 16 full text articles reviewed, with one more study then excluded. 10 studies investigated xylitol-containing chewing gum, and six looked at xylitol candy (one did both). Eight included studies were randomised controlled trials. Data extraction was undertaken by two reviewers. RESULTS: 3466 participants were included in the 10 studies that investigated xylitol chewing gum, and all 10 studies reported a statistically significant preventive effect compared to a no chewing gum or placebo control. In 9 studies, the preventive fraction was clinically significant. The six studies investigating xylitol candies contained a total of 1023 participants, and only one study demonstrated a significant preventative effect. CONCLUSIONS: There is some evidence that incorporating xylitol chewing gum daily has a caries-reducing effect in those with a moderate-to-high baseline caries level. This effect was not present for xylitol sweets.

DESIGN: The study was designed as a single-blinded, parallel, randomized controlled trial to compare the effectiveness of the Salvadora persica toothbrush (MTB), Salvadora persica chewing stick (MCS), and a standard toothbrush (STB) in controlling plaque and gingivitis. A total of 78 participants were randomly divided into three groups and instructed to use their assigned oral hygiene tool in a standardized manner for three. CASE SELECTION: Participants were non-dental students and staff of Universiti Kebangsaan Malaysia, Kuala Lumpur Campus, selected through convenience sampling. They met specific inclusion criteria, such as being systemically healthy, having ≥20 teeth, and having a Basic Periodontal Examination score of 0, 1, or 2, with no periodontal pockets greater than 5.5 mm. DATA ANALYSIS: Clinical outcomes were measured using the Plaque Index (PI) and Periodontal Inflamed Surface Area (PISA) at baseline, one-, and three-weeks post-intervention. Data analysis was performed using mixed-model analysis of variance for continuous variables and Fisher's exact test for categorical variables. RESULTS: All three groups showed significant improvements in plaque levels and severity of gingivitis from baseline to three weeks post-intervention. The MCS group demonstrated a significant improvement in mean PISA values of the anterior teeth compared to the MTB and STB groups. However, there was no significant difference in plaque level reduction or overall gingivitis severity among the three groups. This indicates that when used correctly, Salvadora persica toothbrushes and chewing sticks are as effective as standard toothbrushes in plaque control and gingival health. CONCLUSIONS: The study concludes that both Salvadora persica toothbrushes and chewing sticks can serve as effective alternatives to the standard toothbrush for plaque control and gingival health. This showcases the beneficial anti-plaque and anti-gingivitis properties of Salvadora persica. However, the effectiveness of these oral hygiene tools is contingent upon the correct usage techniques.
RESUMO
DESIGN: An in vitro study to determine the immediate and sustained effect of fluoride varnish and its combination with fluoride toothpastes in preventing the development of root caries. CASE SELECTION: Human root dentine samples (150) were randomly divided into five experimental protocols of 30 specimens each: 1) fluoride varnish (22,600 ppm fluoride and 1-5% CPP-ACP); 2) fluoride varnish followed by Paste One (1100 ppm sodium fluoride and CPP-ACP); 3) fluoride varnish followed by Paste Plus (900 ppm sodium fluoride and CPP-ACP); 4) fluoride varnish followed by Paste One and Paste Plus; and 5) no treatment (control). A layer of varnish was applied to specimens except the control group and was left in situ for 18 h. The varnish layer was removed, and the various toothpaste treatments were initiated. Half of the specimens in each group were assigned to a short-term incubation model in which they were immediately subjected to a 7-day cariogenic challenge consisting of a combination of human saliva and artificial saliva containing 2% sucrose. The other half of the specimens in each group were assigned to the long-term incubation model in which the experimental protocol was continued for 8 weeks before initiating the seven-day cariogenic challenge. The protocols were evaluated by assessing dentine porosity (rhodamine intensity), mineral density, biofilm biomass, and viability assays. DATA ANALYSIS: Confocal laser scanning microscopy was used to determine dentine porosity and Levene's test was used to verify the assumption of equality of variances and normal distribution of errors before two-way ANOVA and the Games-Howell test were carried out at a significance level of 0.05 for both incubation models. Microcomputed tomography was used to determine mineral density with statistical analysis involving Levene's test, two-way ANOVA and Tukey's test at a significance level of 0.05 for both incubation models. Biomass was evaluated using a biofilm biomass assay with analysis of optical density data using Levene's test, ANOVA and Scheffe's test at a significance level of 0.05. RESULTS: For both the short- and long-term incubation models, all the experimental regimes resulted in a statistically significant decrease in dentine porosity and an increase in mineral density when compared to the control group. Fluoride varnish followed by both pastes and fluoride varnish followed by Paste One resulted in a statistically significant decrease in dentine porosity for some depths in both models when compared to fluoride varnish alone. Changes in dentine porosity and mineral density were observed within groups over time. All the experimental regimes demonstrated anti-biofilm effects. Immediate and sustained anti-caries effects were observed for all preventive protocols, with the combination of fluoride varnish and Paste One resulting in superior additional anti-caries effects. CONCLUSIONS: The authors concluded that all protocols demonstrated immediate and sustained anti-caries effects against the development of root caries despite variations in effects over time. The combination of fluoride varnish and Paste One resulted in additional anti-caries effects that were consistently superior, with no additional effects being observed when Paste Plus was added in combination. The authors suggest that, within the study's limitations, topical fluoride varnish seems to have a protective effect on root surfaces for up to eight weeks and that fluoride varnish should be considered as an important adjunct strategy in the prevention of root caries in older adults.

STUDY DESIGN: A randomised parallel controlled clinical trial was conducted between 2013 and 2015 at the University of Sao Paulo, Brazil, to assess the impact of pulpectomy or extraction on the oral health-related quality of life (OHRQoL) of children with pulp necrosis in primary molars. STUDY SELECTION: Children between the ages of 3 and 5 who were in good health but had extensive caries in at least one primary molar with signs of pulpal necrosis (also as seen radiographically, caries reaching the pulp with no signs of internal or external resorption) were considered for inclusion. Additionally, teeth with sufficient structure for rubber dam placement were also included. Children with any systemic, neurological, or other conditions that negatively impacted their growth were excluded. CLINICAL PROCEDURES AND SUCCESS CRITERIA: After computer-generated randomisation, 100 children were assigned randomly into two groups: 50 in the pulpectomy group and 50 in the dental extraction group. A paediatric dentist performed all procedures under local anaesthesia without sedation or general anaesthesia, and a rubber dam was used for pulpectomy with composite restoration in a single session. The OHRQoL scores were evaluated at baseline, 4, 8, and 12 months using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) via face-to-face interviews with parents conducted by a researcher trained in a single-blinded fashion. Additionally, the child's self-reported dental anxiety was measured using the Facial Image Scale (FIS), and dental pain was assessed using the Wong-Baker Faces Pain Scale (WBFPS) immediately after the treatment as secondary outcomes. RESULTS: The mean difference (SD) in the total B-ECOHIS score between baseline and after 12 months was 12.66 (6.79) for the pulpectomy group and 10.94 (9.28) for the extraction group, with effect sizes of 3.2 (95% CI: 2.42-4.20) and 1.4 (95% CI: 0.84-2.11), respectively. While both treatments significantly improved the children's OHRQoL after 12 months, the pulpectomy group showed greater long-term improvement compared to the extraction group, with mean differences (SD) of 4.86 (6.13) and effect sizes of 0.8 (0.46-1.13; p < 0.001). Moreover, children in the extraction group showed higher levels of anxiety compared with those in the pulpectomy group at 12-month follow-up (OR = 2.52; 95% CI = 1.30-4.89), and they reported 93% more odds of 'dental pain with high level' immediately after treatment than those in the pulpectomy group (OR = 1.93; 95% CI = 0.83-4.49). CONCLUSION: Children treated with pulpectomy in their necrotic primary molars were found to have better OHRQoL than those who had their primary molars extracted.

DESIGN: This retrospective cohort study used treatment claims data submitted over a 10-year period to explore the effect of water fluoridation on specified National Health Service (NHS) dental treatments, number of Decayed Missing and Filled Teeth (DMFT) and its cost-effectiveness. Ethical approval was granted and data was collected from NHS primary care settings via claims submitted to the NHS Business Services Authority (NHS BSA). To be included, participants must have attended dental services twice in the study period, been 12 years or over and had a valid English postcode. Those with claims related solely to orthodontic care were excluded, as were those who had requested NHS National Data Opt-out. Costs relating to water fluoridation were supplied by Public Health England. NHS BSA data was used to calculate NHS costs at 2020 prices. COHORT SELECTION: A personalised water fluoride exposure for the 2010-2020 period was assigned to all individuals, who were then split into two groups, above 0.7 mg F/L (optimally fluoridated group) or lower (non-optimally fluoridated group). Individuals in each group were matched for analysis using propensity scores, estimated via logistic regression. DATA ANALYSIS: Values of absolute standardised mean differences were used to determine covariate balance between the two groups, alongside a generalised linear model with matching weights and cluster robust standard errors and a patient deprivation decile as an interaction term. An Incremental Cost-Effectiveness Ratio (ICER) was calculated and differences in the overall costs to the public sector were illustrated by the return on investment estimate. RESULTS: The cohort contained data on 6,370,280 individuals. Negative binomial regression models were used to analyse health outcomes. In the optimally fluoridated group, the rate of invasive dental treatments was 3% less than in the non-optimally fluoridated group, and the mean DMFT in the optimally fluoridated group was 2% lower. There was no evidence of a difference in the predicted mean number of missing teeth between groups. There was a small reduction in the predicted number of invasive treatments in the optimally fluoridated group but the largest predicted reduction was in the most deprived decile. DMFT did not exhibit the expected social inequalities gradient, and for the mean number of missing teeth there were small differences in each decile of deprivation between groups but the direct effect was inconsistent. Water fluoridation expenditure between 2010 and 2019 was estimated to be £10.30 for those receiving optimally fluoridated water. The marginal effects estimate illustrated savings of £22.26 per person (95% CI - £21.43, -£23.09), which is a relative reduction in costs to the NHS of 5.5% per patient. A subsequent estimation of cost effectiveness calculated the cost of water fluoridation to avoid one invasive dental treatment (the ICER) as £94.55. The estimated return on investment using a variety of NHS dental attendance estimates all lead to a positive return. CONCLUSIONS: These results suggest that water fluoridation appears to be producing less impactful effects on oral health, with water fluoridation resulting in 'exceedingly small' health effects and very small reductions in use of NHS dental services. A positive return for the public sector was identified as the costs of NHS dentistry are high and costs of water fluoridation are low, though this study did not include the original set up costs of fluoridation programmes.
RESUMO
AIM: The aim of this study was to compare the environmental footprint of eight inter-dental cleaning aids. MATERIALS AND METHODS: A comparative life cycle analysis was conducted based on an individual person using inter-dental cleaning aids every day for 5 years. The primary outcome was a life cycle impact assessment. This comprised of 16 discrete measures of environmental sustainability (known as impact categories), for example, greenhouse gas emissions (measured in kilograms of carbon dioxide equivalent, or kg CO2 e), ozone layer depletion (measured in kilograms of chloroflurocarbon equivalent, or kg CFCe), and water use (measured in cubic metres). Secondary outcomes included normalized data, disability-adjusted life years, and contribution analysis. RESULTS: Inter-dental cleaning using floss picks had the largest environmental footprint in 13 of 16 impact categories. Depending on the environmental impact category measured, the smallest environmental footprint came from daily inter-dental cleaning with either bamboo inter-dental brushes (five impact categories, including carbon footprint), replaceable head inter-dental brushes (four impact categories), regular floss (three impact categories), sponge floss (three impact categories), and bamboo floss (one impact category). CONCLUSIONS: Daily cleaning with inter-dental cleaning aids has an environmental footprint that varies depending on the product used. Clinicians should consider environmental impact alongside clinical need and cost when recommending inter-dental cleaning aids to patients.

INTRODUCTION: "The Graduating European Dentist" Curriculum (GED) was adopted in 2020 by the Irish Dental Council as its new expectation for competencies. The Dublin Dental University Hospital (DDUH) sought to map the teaching activities for its undergraduate dental training programme to the GED. This paper describes the process developed for curriculum mapping. MATERIALS AND METHODS: Guided by historical mapping data and materials on the DDUH's virtual learning environment; teaching activities in a bespoke curriculum mapping system were edited, added and/or deleted to match existing teaching activities currently delivered by staff to students. These activities were then remapped to GED Learning Outcomes. Staff members with oversight responsibilities for a collection of activities then received and provided feedback on reports tabulating the preliminary map. Feedback from staff members around their activities was accommodated to produce an accurate reflection of teaching activities across the 5 years program. RESULTS: A process for mapping existing teaching activities to a new set of curriculum expectations using a bespoke application and several other widely available technologies was established. Informal feedback from staff has been positive and has raised ideas for future opportunities to improve the alignment of educational activities with learning outcomes. CONCLUSION: Other dental schools may find this accounting of the DDUH's efforts useful in guiding their own curriculum mapping.

OBJECTIVES: Dental graduates must graduate with high levels of clinical skills. Education in the clinical environment needs to be more than didactic supervision of practice by clinical teachers. Appropriate feedback in this context, is therefore critical to the development of student competence and confidence. This study was conducted to enhance and develop the assessment and feedback processes during clinical sessions in a Dental University Hospital in an effort to contribute to the development of students' self-assessment skills, reflective ability and clinical competence. METHODS: A new evidence-based model of feedback was introduced between clinical teachers and dental students. The implementation of this model was evaluated by students through a survey and focus groups. Descriptive and inferential statistics were applied to the quantitative data, while thematic analysis applied to the qualitative data. RESULTS: Findings from the survey indicated that students perceived the new model of feedback to be a positive addition to their learning experiences. The majority indicated a preference to continue using it. Quantitative analysis also demonstrated that students placed a high value on the feedback they received through the new model and associated it with improved individual performance. Five themes generated from the qualitative analysis echoed the perception that the model of feedback enhanced learning opportunities, especially when it was focused on individual performance and incorporated peer feedback. Students' preferences in relation to feedback processes were also gleamed from quantitative and qualitative analyses, that is, provision of positive and constructive feedback, both in dialogue and in written formats, delivered during and after each clinical session and addressing their individual competency learning goals for the future. Some challenges to be addressed were also identified (e.g., time constraints, inter-personal issues, and non-conducive environments). CONCLUSIONS: Feedback is central to learning and remains a complex and challenging area. By adopting effective and evidence-based feedback practices through the introduction of a feedback model, students can be supported in regulating their own learning in the clinical learning environment.

The purpose of this Consensus Statement is to provide a global, collaborative, representative and inclusive vision for educating an interprofessional healthcare workforce that can deliver sustainable healthcare and promote planetary health. It is intended to inform national and global accreditation standards, planning and action at the institutional level as well as highlight the role of individuals in transforming health professions education. Many countries have agreed to 'rapid, far-reaching and unprecedented changes' to reduce greenhouse gas emissions by 45% within 10 years and achieve carbon neutrality by 2050, including in healthcare. Currently, however, health professions graduates are not prepared for their roles in achieving these changes. Thus, to reduce emissions and meet the 2030 Sustainable Development Goals (SDGs), health professions education must equip undergraduates, and those already qualified, with the knowledge, skills, values, competence and confidence they need to sustainably promote the health, human rights and well-being of current and future generations, while protecting the health of the planet.The current imperative for action on environmental issues such as climate change requires health professionals to mobilize politically as they have before, becoming strong advocates for major environmental, social and economic change. A truly ethical relationship with people and the planet that we inhabit so precariously, and to guarantee a future for the generations which follow, demands nothing less of all health professionals.This Consensus Statement outlines the changes required in health professions education, approaches to achieve these changes and a timeline for action linked to the internationally agreed SDGs. It represents the collective vision of health professionals, educators and students from various health professions, geographic locations and cultures. 'Consensus' implies broad agreement amongst all individuals engaged in discussion on a specific issue, which in this instance, is agreement by all signatories of this Statement developed under the auspices of the Association for Medical Education in Europe (AMEE).To ensure a shared understanding and to accurately convey information, we outline key terms in a glossary which accompanies this Consensus Statement (Supplementary Appendix 1). We acknowledge, however, that terms evolve and that different terms resonate variably depending on factors such as setting and audience. We define education for sustainable healthcare as the process of equipping current and future health professionals with the knowledge, values, confidence and capacity to provide environmentally sustainable services through health professions education. We define a health professional as a person who has gained a professional qualification for work in the health system, whether in healthcare delivery, public health or a management or supporting role and education as 'the system comprising structures, curricula, faculty and activities contributing to a learning process'. This Statement is relevant to the full continuum of training - from undergraduate to postgraduate and continuing professional development.

BACKGROUND: Webinars have recently replaced in-person medical conferences, including paediatric cardiology conferences, given the COVID-19 pandemic. METHODS: With increasing environmental concerns, we analysed the differences between the environmental footprint of a paediatric cardiology webinar with a hypothetical conference. Travel data was collected, with assumptions made on the amount of computer use, internet use and accordingly the overall use of electricity for both forms of conference. Life Cycle Assessment methodology was used (OpenLCA and Ecovinvent v 3.7). RESULTS: We showed that the theoretical environmental impact of a virtual conference is significantly less (4 tons CO2 equivalent) than the traditional international face-to-face conference (192 tons CO2 equivalent). The life cycle assessment methodology showed that resource use for a face-to-face conference lasting 2.5 days for 1374 attendees is equivalent to 400 times what an average person would use in one year, the climate change and photochemical ozone formation approximately 250 times and the eutrophication terrestrial equivalent to 225 times. However, using carbon equivalent emissions to measure environmental harm from flying is an under estimate of the potential damage, when one considers the additional production of airplane contrails. Notwithstanding this, there is a 98% reduction in climate change impact when meetings are held virtually. CONCLUSIONS: While the virtual conference may never completely replace the traditional in-person paediatric cardiology conference, due to networking benefits, the significant theoretical benefits to the environment highlighted in this study, warrants consideration for the virtual conference taking a more common place in sustainable academia.

INTRODUCTION: Evidence concerning the interactions between human health and planetary health has grown extensively in recent years. In turn, the perceived importance of environmental sustainability within higher education is growing at a rapid rate. This paper provides a summary of key elements as they apply to dentistry, and provides an introduction to the reader of an early consensus of how sustainability could be included as part of the dental curriculum. METHODS: The consensus opinion within this paper largely centres around discussion at the ADEE sustainability workshop at the annual conference in Berlin (August 2019). In order to help inform discussions at the workshop, a brief scoping questionnaire was circulated to potential participants regarding their understanding and current teaching practices in sustainability. An infographic was designed to help delegates remember the important elements of sustainable dentistry. Delegates discussed the concept of sustainability alongside the infographic, and how they could link these with the Graduating European Dentist (GED) curriculum. RESULTS: The discussions within the workshop largely centred around 4 main themes: Disease prevention and health promotion, Patient education and empowerment, Lean service delivery and Preferential use of strategies with lower environmental impact. DISCUSSION: It is apparent that there is a widespread need for teaching materials relating to environmental sustainability; this includes specific learning outcomes relating to the 4 educational domains of the Graduating European Dentist curriculum, and methods for teaching and assessing these outcomes. CONCLUSION: This paper reports consensus on the first phase of a pan-European working group on Sustainability in dental education.

BACKGROUND: To analyse via life cycle analysis (LCA) the global resource use and environmental output of the endodontic procedure. METHODOLOGY: An LCA was conducted to measure the life cycle of a standard/routine two-visit RCT. The LCA was conducted according to the International Organization of Standardization guidelines; ISO 14040:2006. All clinical elements of an endodontic treatment (RCT) were input into OpenLCA software using process and flows from the ecoinvent database. Travel to and from the dental clinic was not included. Environmental outputs included abiotic depletion, acidification, freshwater ecotoxicity/eutrophication, human toxicity, cancer/non cancer effects, ionizing radiation, global warming, marine eutrophication, ozone depletion, photochemical ozone formation and terrestrial eutrophication. RESULTS: An RCT procedure contributes 4.9 kg of carbon dioxide equivalent (CO2 eq) emissions. This is the equivalent of a 30 km drive in a small car. The main 5 contributors were dental clothing followed by surface disinfection (isopropanol), disposable bib (paper and plastic), single-use stainless steel instruments and electricity use. Although this LCA has illustrated the effect endodontic treatment has on the environment, there are a number of limitations that may influence the validity of the results. CONCLUSIONS: The endodontic team need to consider how they can reduce the environmental burden of endodontic care. One immediate area of focus might be to consider alternatives to isopropyl alcohol, and look at paper, single use instrument and electricity use. Longer term, research into environmentally-friendly medicaments should continue to investigate the replacement of current cytotoxic gold standards with possible natural alternatives. Minimally invasive regenerative endodontics techniques designed to stimulate repair or regeneration of damaged pulp tissue may also be one way of improving the environmental impact of an RCT.

Data sources Medline-PubMed, Scopus and Embase databases.Study selection Controlled clinical trials studies with at least one month follow-up that utilised locally or systemically delivered statins as a sole adjunctive treatment to mechanical periodontal therapy in patients diagnosed with chronic or aggressive periodontitis were included. Selection was carried out independently by two reviewers. Data extraction and synthesis Data were extracted to a spreadsheet with authors being contacted for missing data. Risk of bias for randomised controlled trials was assessed using the Cochrane tool with the ROBINS-I tool being used for non-randomised studies. Weighted mean differences between baseline and six months after periodontal treatment for clinical attachment level (CAL), probing pocket depth (PPD) and intrabony defect (IBD) were calculated.Results Fifteen studies were incorporated in the systematic review, with ten investigations included in the meta-analysis. In the meta-regression, the additional use of simvastatin, rosuvastatin and atorvastatin decreased pocket depth in contrast with mechanical periodontal treatment and a placebo gel (p < 0.05). Simvastatin and rosuvastatin significantly reduced the development of intrabony defect in contrast with control group (p < 0.05). Statins failed to provide a statistically significant difference between the adjunct therapy for both periodontal pocket depth and intrabony defect (p < 0.05). Simvastatin provided a statistically significant improvement in clinical attachment level gain, as compared to the control group (2.02 ± 0.79 mm; p = 0.043). Conclusions Improvements in periodontal parameters were observed with the use of statins as adjunct to mechanical periodontal therapy. Simvastatin was the main medication that demonstrated additional advantages in all assessed parameters. The use of statins in relationship with non-surgical scaling and root planing provided better clinical periodontal outcomes.

Of the selected studies for final inclusion in the systematic review, study quality was assessed using the critical appraisal worksheet for randomised controlled trials from the Oxford Centre for Evidence-Based Medicine (CEBM 2005). Prevented fraction (PF), number needed to treat (NNT) and relative risk (RR) were calculated as outcome measures in each study. In addition, the published evidence on SDF was reviewed in order to formulate clinical recommendations on safety and effectiveness when treating root or coronal caries in an adult population with SDF, as well as treatment of dental hypersensitivity.ResultsThree randomised controlled trials were identified that addressed the effectiveness of SDF on root caries in older adults, but none addressed coronal caries. Root caries prevented fraction and arrest rate for SDF were significantly higher than placebo. The prevented fraction for caries prevention for SDF compared to placebo was 71% in a three-year study and 25% in a two-year study. The prevented fraction for caries arrest for SDF was 725% greater in a 24-month study and 100% greater than placebo in a 30-month study. No severe adverse effects were observed.ConclusionsExisting reports of SDF trials support effectiveness in root caries prevention and arrest, remineralisation of deep occlusal lesions and treatment of hypersensitive dentine.

Data sourcesA comprehensive literature search in all languages was carried out. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (till 6 October 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2016, Issue 9), MEDLINE Ovid (1946 till October 6th, 2016), Embase Ovid (1980 till October 6th, 2016) and EThOS (till October 6th, 2016). ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. Authors were contacted to clarify study information.Study selectionThe inclusion criteria of studies were defined as patients undergoing orthodontic treatment, up to 18 years of age. INTERVENTIONS: orthodontic treatment, exposure: non-pharmacological orthodontic pain intervention (low-level laser therapy, vibratory stimulation, chewing adjuncts, brain wave music or cognitive behavioral therapy and post-treatment communication 'text message'). OUTCOME: pain.Data extraction and synthesisTwo authors reviewed each study independently. A third author was used to resolve any disagreement on the eligibility of the included studies. The authors excluded papers that had unsuitable study design, and assessed the risk of bias on each paper they included. Data were combined using a random effect model and expressed results as mean differences (MD) with 95% confidence intervals (CIs).ResultsThe authors included 14 randomised controlled trials (RCTs) that randomised 931 participants. Intervention modalities included: low-level laser therapy (LLLT) (four studies); vibratory devices (five reviews); chewing adjuncts (three studies); brainwave music or cognitive behavioral therapy (one study) and post-treatment communication in the form of a text message (one study). Twelve studies involved self-report assessment of pain on a continuous scale and two studies used questionnaires to assess the nature, intensity and location of pain. The combined data from two studies involving 118 participants provided low-quality evidence that LLLT reduced pain at 24 hours by 20.27 mm (95% CI -24.50 to -16.04, P < 0.001; I² = 0%). LLLT also appeared to reduce pain at six hours, three days and seven days. The results for the other comparisons are inconclusive due to low evidence quality.ConclusionsThe overall results of the current study are inconclusive. There is low quality evidence that non-pharmacological interventions reduce pain during orthodontic treatment.

Data sourcesPubMed, EMBASE, Web of Science, Cochrane library, China Biology Medicine Disc (CBM), China National Knowledge infrastructure (CNKI).Study SelectionThis study included only human randomised controlled trials (RCTs) and clinical controlled trials (CCTs). To be included studies had to include patients prescribed oral anticoagulant therapy (OAT) requiring dental extraction(s). Comparison was made between patients discontinuing OAT for the dental extraction(s) and those continuing with their OAT. The outcome measured was post-operative bleeding identified by clinician or patient.Data extraction and synthesisThe methods of data extraction were based on the Cochrane Handbook for Systematic Reviews of Interventions. The search was carried out by two reviewers from the data sources listed above. There was no indication of hand searching references of relevant studies or reputable publications, nor any mention of contacting clinical experts or researchers in this field. Language restrictions were unclear. The included studies were assessed for bias using a seven point classification, and a clear traffic light diagram was included to demonstrate the risk of bias of the included studies.ResultsNine hundred and sixty-eight studies were identified with six meeting the inclusion and exclusion criteria. Of the six studies, four were RCTs and two were CCTs encompassing 314 subjects who continued their OAT during tooth extraction(s) and 277 who discontinued their OAT to allow for tooth extraction(s). Five of the six studies were found to have high risk of bias.A meta-analysis of the six studies was conducted. The incidence of post-operative bleeding was 10.8% where OAT was continued and 8.3% where it was discontinued, showing no statistically significant difference. The relative risk ratio to continuing OAT during tooth extraction was 1.31 and 95% confidence interval, albeit with a wide range of 0.79-2.14.ConclusionsAccording to the current literature available on this subject, the results of this meta-analysis suggest that patients continuing OAT during tooth extraction do not have an increased incidence of post-operative bleeding following tooth extraction compared to patients who discontinue their OAT.
