Implementation issues and barriers for assessing oral health in dependent patients after stroke: A qualitative study.

OBJECTIVES: To explore implementation issues and potential barriers for assessing oral health in dependent post-stroke patients. METHODS: Semi-structured interviews were conducted with a purposively identified sample of healthcare service providers who work in two National Health Service (NHS) Trusts in the north of England. Interviews were conducted until data saturation was achieved (n = 30). Data were analysed using the constant comparative method. RESULTS: Six themes were drawn out in this study, which described potential barriers to assessing oral health in post-stroke patients, aspects of oral health that need assessment, streamlining the oral health assessment, input methods for oral health assessment, characteristics of assessors, and how oral care should be planned. CONCLUSIONS: Assessment of oral health for post-stroke patients has been viewed as a complex task because of several identified barriers. Several suggestions have been proposed to overcome these barriers, aiming to enable more feasible and effective oral health assessments for post-stroke patients. CLINICAL SIGNIFICANCE: The findings from this study have the potential to contribute to developing oral health measurement instruments that might be more successfully implemented and guide oral care planning for dependent patients after stroke.

Establishing an empirical conceptual model of oral health in dependent adults: Systematic review.

AIM: This qualitative evidence synthesis was performed to establish a conceptual model of oral health in dependent adults that defines the construct of oral health and describes its interrelationships based on dependent adults' and their caregivers' experiences and views. METHODS: Six bibliographic databases were searched: MEDLINE, Embase, PsycINFO, CINAHL, OATD, and OpenGrey. Citations and reference lists were manually searched. A quality assessment of included studies was conducted independently by two reviewers using the Critical Appraisal Skills Programme (CASP) checklist. The 'best fit' framework synthesis method was applied. Data were coded against an a priori framework and data not captured by this framework were thematically analyzed. To assess the confidence of the findings from this review, the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach was used. RESULTS: Twenty-seven eligible studies were included from 6126 retrieved studies. Four themes were generated to further understand oral health in dependent adults: oral health status, oral health impact, oral care, and oral health value. CONCLUSION: This synthesis and conceptual model offer a better understanding of oral health in dependent adults and subsequently provide a starting point to guide establishment of person-centred oral care interventions.

Oral health decline in patients after stroke: a qualitative study.

Introduction To develop and implement effective oral care interventions for patients after stroke, there is a need to understand the causes behind the decline in their oral health. This qualitative study was, therefore, undertaken to explore experiences and views of health service providers about the causes of oral health decline in this group of patients.Methods A purposively selected sample of healthcare service providers who work in two NHS Trusts in the North of England were interviewed utilising a semi-structured interview technique. Interviews were conducted with the assistance of a topic guide and continued until data saturation (n = 30) was reached. The constant comparative approach was used to analyse the data.Results Two major factors, perceived by the participants, were thought to cause oral health decline in patients after stroke. Post-stroke neurological deficits resulting in oral-related functional disturbances was the first. The second was the barriers leading to difficulties in performing or receiving daily oral care. These barriers were related to the patients, their service providers, or the environment in which care is being delivered.Conclusions This study described the major factors affecting the oral health of patients after stroke, which can offer a starting point for developing effective oral care interventions for them.

Measurement properties, interpretability and feasibility of instruments measuring oral health and orofacial pain in dependent adults: a systematic review.

BACKGROUND: Dependent adults have been shown to have a greater experience of oral health deterioration and orofacial pain. This is partly because their non-dental caregivers may not easily identify oral health problems and orofacial pain experienced by them. Thus, this systematic review aimed to investigate measurement properties, interpretability and feasibility of instruments assessing oral health and orofacial pain in dependent adults, which can be used by the non-dental caregivers to establish oral care plans for those who are dependent upon them. METHODS: Seven bibliographic databases were searched: MEDLINE, Embase, CINAHL, CENTRAL, HTA, OATD and OpenGrey. Citations and reference lists of the included studies were also manually searched. Two authors independently screened titles and abstracts, and then full texts. A quality assessment of included studies was conducted independently by two authors using the COSMIN Risk of Bias checklist. The best evidence synthesis method was used to synthesise results from different studies for each measurement property per measurement instrument by integrating the overall rating for each measurement property per measurement instrument with its quality level of evidence. RESULTS: Nineteen eligible studies were included, which reported the development, measurement properties' evaluation, interpretability and feasibility of nine oral health and three orofacial pain measurement instruments. Methodological quality of the included studies ranged from very good to inadequate. None of the identified measurement instruments has been adequately and comprehensively tested. CONCLUSIONS: While several measurement instruments were identified in this systematic review, more evidence is needed to be able to more comprehensively evaluate these instruments. Among those identified, the OPS-NVI demonstrated sufficient construct validity, while the OHAT and the THROAT demonstrated sufficient reliability. These instruments therefore have potential for future use with more confidence once other measurement properties, interpretability and feasibility have been sufficiently tested and evaluated.

From inputs to outputs: an analysis of the changes to learning outcomes for dental undergraduate education in the UK.

Introduction/aims Preparing for practice (PfP) was thought to represent a significant shift in the expectations of dental undergraduates compared to its predecessor, The first five years (TFFY). This project aimed to explore requirement changes by comparing learning outcomes for undergraduate dentists in these two documents. Changes in curriculum requirements defining clinical, professional, or a blend of these skills were also investigated.Methods Curriculum mapping was used to compare learning outcomes in PfP to requirements in TFFY.Results The total number of learning outcomes increased from 101 to 149 in PfP compared to TFFY. There was a proportional reduction in outcomes describing clinical skills and an increase in the proportion of outcomes describing professional and blended skills. Three TFFY requirements did not appear in PfP and a further 23 learning outcomes in PfP were absent in TFFY.Conclusions In the transition from TFFY to PfP, there has been an overall increase in the number of outcomes graduates must attain before they can register with the General Dental Council. There are more outcomes defining professionalism which subsequently has resulted in proportional but not actual decrease in outcomes related to clinical skills. While there is uncertainty over how schools have managed curricula to incorporate these changes and thus whether the perception of graduate preparedness can be directly attributable to these changes, it is timely to consider any changes within dental learning outcomes in the context of preparedness concerns.

Undergraduate dental education: an education or training?

The impact of the COVID-19 pandemic on undergraduate dental education has led to new ways of working, different modes of delivery for elements of programmes and, in some cases, revised timelines for progression. These expedient changes, like the virus, may be with us for some time. However, as we come out of an intense period of critical reflection and change, it may also offer us an opportunity and impetus to revisit unresolved challenges around the focus and role of undergraduate dental education. We reflect upon the necessity for both clinical development and scholarship for our undergraduates, and the subtle differences of purpose between education and training. We consider whether it is time to look afresh at the relationship between the universities and other stakeholders and perhaps also to start with renewed understanding, giving deeper consideration to the value of each. One of the biggest obstacles to resolving these issues is to consider how best we align institutional requirements with the education and training of healthcare practitioners. With the hindsight of the past 12 months, we would argue that such a review is timely and more meaningful as we can reflect on the pandemic-enforced and expedient changes to our programmes and more clearly understand where our future priorities lie.

Impact of diabetes and periodontal status on life quality.

OBJECTIVES: To investigate impact of periodontal status on quality of life (QoL) in type-1 (T1D) and type-2 (T2D) diabetes patients pre- and post-periodontal treatment using the Well-being Questionnaire 12 (W-BQ12) and Audit of Diabetes-Dependent Quality of Life-19 (ADDQoL-19). METHODS: W-BQ12 and ADDQoL-19 were self-completed by 56 T1D and 77 T2D patients at baseline and by those with periodontitis 3 and 6-months after therapy. RESULTS: At baseline, T1D patients had significantly higher general W-BQ12 [Median (IQR); 24.00 (20.25-27.75)] and positive well-being scores [8.00 (6.00-9.00)] (indicating better QoL) compared to T2D patients [22.00 (15.50-26.00) and 6.00 (3.50-9.00)], respectively (p < 0.05). Within both groups, general W-BQ12 scores did not differ significantly between patients with periodontal health, gingivitis, or periodontitis (p > 0.05). Significantly higher general W-BQ12 scores were observed in T1D patients at month 3 [28.00 (22.00-29.50)] compared to baseline [22.00 (17.00-24.50)] (p < 0.01), suggesting an initial improvement in QoL post-treatment. ADDQoL-19 identified that diabetes had greatest impact on the domain 'freedom to eat', with participants placing most importance on 'family life'. No significant changes in ADDQoL-19 scores were seen post-treatment (p > 0.05). CONCLUSIONS: Diabetes had impacts upon aspects of life quality in both T1D and T2D patients, though any additional impact based on periodontal status was not observed when using W-BQ12 and ADDQoL-19.

Examining the impact of oral hygiene advice and/or scale and polish on periodontal disease: the IQuaD cluster factorial randomised controlled trial.

Objective To compare the clinical effectiveness and cost benefit of different frequencies of scale and polish (S&P) treatments in combination with different types of oral hygiene advice (OHA).Design Multi-centre, multi-level cluster randomised factorial open trial with blinded outcome evaluation. UK dental practices were cluster randomised to deliver OHA as usual or personalised. In a separate randomisation, patients were allocated to receive S&P 6-monthly, 12-monthly or never.Setting UK primary dental care.Participants Practices providing NHS care and adults who had received regular dental check-ups.Main outcome measures The percent of sites with bleeding on probing, patient confidence in self-care, incremental net benefits (INB) over three years.Results Sixty-three practices and 1,877 adult patients were randomised and 1,327 analysed (clinical outcome). There was no statistically significant or clinically important difference in gingival bleeding between the three S&P groups (for example, six-monthly versus none: difference 0.87% sites, 95% CI: 1.6 to 3.3, p = 0.48) or between personalised or usual OHA groups (difference -2.5% sites, -95%CI: -8.3 to 3.3, p = 0.39), or oral hygiene self-efficacy (cognitive impact) between either group (for example, six-monthly versus none: difference -0.028, 95% CI -0.119 to 0.063, p = 0.543). The general population place a high value on, and are willing to pay for, S&P services. However, from a dental health perspective, none of the interventions were cost-effective.Conclusion Results suggest S&P treatments and delivering brief personalised OHA provide no clinical benefit and are therefore an inefficient approach to improving dental health (38% of sites were bleeding whatever intervention was received). However, the general population value both interventions.

Differences in treatment outcomes of definitive fixed implant-supported restorations with or without an interim restoration: A systematic review.

STATEMENT OF PROBLEM: Guidance to determine whether providing an interim implant-supported restoration is beneficial is lacking. PURPOSE: The purpose of this systematic review was to answer the following focused question: "Does the use of interim fixed implant prostheses before placement of a definitive fixed implant-supported prostheses impact esthetics, peri-implant health, and osseointegration in partially dentate adults?" MATERIAL AND METHODS: A search of electronic databases (Medline and Embase) and the nonpeer-reviewed literature for randomized controlled trials, systematic reviews, and cohort studies in the English language was conducted. RESULTS: Two studies met the eligibility criteria. Heterogeneity of the study methodologies and outcome measures did not allow for meta-analysis. Use of interim implant-supported restorations may improve the esthetic outcome. Occlusal loading of definitive implant-supported prosthesis without the use of an interim restoration may decrease chair time and the number of patient visits. CONCLUSIONS: The systematic review has found insufficient evidence to support or refute the practice of providing an interim restoration before delivering an implant-supported prosthesis.

Professionalism in undergraduate dental education: a pause for thought.

Professionalism in dental education, as well as in the wider dental profession, is a regularly discussed and debated topic. It may seem obvious what is meant by 'professionalism' and in many situations it is clear what constitutes a professional approach or behaviour, but contention exists in how to articulate, measure and consider aspects of this complex and context dependent phenomenon. Getting 'it' right early on, with our students and new graduates, is a strategic priority, contributing to 'upstream' activities which have an intention of preventing future issues or harm. The aim of this article is to summarise the challenges faced by providers of undergraduate education (and the dental regulator) in the UK in defining and determining attainment of 'professionalism' before registration. It is timely to take an opportunity for pause, re-assess frameworks and consider future direction.

Delivering to 'that list': the challenges of working with learning outcomes.

Dental education providers have raised concerns around the challenges experienced when trying to demonstrate student attainment of 'professionalism', as described in the General Dental Council (GDC) document 'Preparing for practice'. This manuscript describes a documentary analysis of each 'outcome' within the dentist professionalism domain section, with an assessment of whether it met the criteria of a functional learning outcome. In addition, outcomes were scrutinised in terms of application within undergraduate degree programmes. Key challenges identified were: the 'outcome list' included standards and objectives as well as outcomes; not all statements were specific and focused, some were broad and multi-faceted; determining attainment where there was no identifiable endpoints; and judging achievability within the supervised and confined environment of undergraduate programmes. We conclude that issues have been created through the way that these learning outcomes have been expressed. Also, it is evident that there are ideological and philosophical issues about accurately articulating the attainment of complex phenomena like professionalism. The findings from this study reflect the challenges associated with using learning outcomes to adequately capture professionalism, the values that underpin it and the behaviours that manifest its existence in clinical practice.

Exploring a temporal relationship between biofilm microbiota and inflammatory mediators during resolution of naturally occurring gingivitis.

BACKGROUND: This study uses multiple, contemporary methodologies to expand our knowledge of the temporal relationship between host-microbial interactions and clinical signs of gingivitis. METHODS: Subgingival plaque and crevicular fluid samples were collected from 31 systemically healthy adults with naturally occurring plaque-induced gingivitis. Professional prophylaxis was administered and participants were followed over 7 weeks. Microbial characterization was performed using a bead-based hybridization assay and cytokine analysis using bead-based flow cytometry. RESULTS: The provision of sequential interventions, oral hygiene instruction, and subsequent professional prophylaxis brought about significant reduction of plaque and resolution of gingivitis at all post baseline time points (P < 0.0001). Candidate cytokines that increased significantly (95% level) were interleukin (IL)-1ß, matrix metalloproteinases (MMP)-1, MMP-3, MMP-8, MMP-9, from baseline to week 2; regulated on activation, normal T cell expressed and secreted (RANTES) at week 4 and week 8; macrophage inflammatory protein (MIP)-1α and MIP-1ß at week 8. Resolution of inflammation was accompanied by a shift in the microbiological flora toward those species associated with health. CONCLUSIONS: This study provides further evidence of the dynamic relationships that exist between the overt clinical signs, the microbial biofilm, and the host response in gingivitis and upon resolution following clinical interventions. Understanding the interactions between the host immune system and subgingival microbial communities during the resolution of established gingivitis continues to evolve as additional knowledge is achieved through using new analytical technologies. The present study confirms a critical effect of oral hygiene measures on restoration of microbial eubiosis in subgingival communities, confirming the important role for home care and professional intervention in maintaining oral health.

Improving the Quality of Dentistry (IQuaD): a cluster factorial randomised controlled trial comparing the effectiveness and cost-benefit of oral hygiene advice and/or periodontal instrumentation with routine care for the prevention and management of periodontal disease in dentate adults attending dental primary care.

BACKGROUND: Periodontal disease is preventable but remains the most common oral disease worldwide, with major health and economic implications. Stakeholders lack reliable evidence of the relative clinical effectiveness and cost-effectiveness of different types of oral hygiene advice (OHA) and the optimal frequency of periodontal instrumentation (PI). OBJECTIVES: To test clinical effectiveness and assess the economic value of the following strategies: personalised OHA versus routine OHA, 12-monthly PI (scale and polish) compared with 6-monthly PI, and no PI compared with 6-monthly PI. DESIGN: Multicentre, pragmatic split-plot, randomised open trial with a cluster factorial design and blinded outcome evaluation with 3 years' follow-up and a within-trial cost-benefit analysis. NHS and participant costs were combined with benefits [willingness to pay (WTP)] estimated from a discrete choice experiment (DCE). SETTING: UK dental practices. PARTICIPANTS: Adult dentate NHS patients, regular attenders, with Basic Periodontal Examination (BPE) scores of 0, 1, 2 or 3. INTERVENTION: Practices were randomised to provide routine or personalised OHA. Within each practice, participants were randomised to the following groups: no PI, 12-monthly PI or 6-monthly PI (current practice). MAIN OUTCOME MEASURES: Clinical - gingival inflammation/bleeding on probing at the gingival margin (3 years). Patient - oral hygiene self-efficacy (3 years). Economic - net benefits (mean WTP minus mean costs). RESULTS: A total of 63 dental practices and 1877 participants were recruited. The mean number of teeth and percentage of bleeding sites was 24 and 33%, respectively. Two-thirds of participants had BPE scores of ≤ 2. Under intention-to-treat analysis, there was no evidence of a difference in gingival inflammation/bleeding between the 6-monthly PI group and the no-PI group [difference 0.87%, 95% confidence interval (CI) -1.6% to 3.3%; p = 0.481] or between the 6-monthly PI group and the 12-monthly PI group (difference 0.11%, 95% CI -2.3% to 2.5%; p = 0.929). There was also no evidence of a difference between personalised and routine OHA (difference -2.5%, 95% CI -8.3% to 3.3%; p = 0.393). There was no evidence of a difference in self-efficacy between the 6-monthly PI group and the no-PI group (difference -0.028, 95% CI -0.119 to 0.063; p = 0.543) and no evidence of a clinically important difference between the 6-monthly PI group and the 12-monthly PI group (difference -0.097, 95% CI -0.188 to -0.006; p = 0.037). Compared with standard care, no PI with personalised OHA had the greatest cost savings: NHS perspective -£15 (95% CI -£34 to £4) and participant perspective -£64 (95% CI -£112 to -£16). The DCE shows that the general population value these services greatly. Personalised OHA with 6-monthly PI had the greatest incremental net benefit [£48 (95% CI £22 to £74)]. Sensitivity analyses did not change conclusions. LIMITATIONS: Being a pragmatic trial, we did not deny PIs to the no-PI group; there was clear separation in the mean number of PIs between groups. CONCLUSIONS: There was no additional benefit from scheduling 6-monthly or 12-monthly PIs over not providing this treatment unless desired or recommended, and no difference between OHA delivery for gingival inflammation/bleeding and patient-centred outcomes. However, participants valued, and were willing to pay for, both interventions, with greater financial value placed on PI than on OHA. FUTURE WORK: Assess the clinical effectiveness and cost-effectiveness of providing multifaceted periodontal care packages in primary dental care for those with periodontitis.

Oral care after stroke: Where are we now?

PURPOSE: There appears to be an association between poor oral hygiene and increased risk of aspiration pneumonia - a leading cause of mortality post-stroke. We aim to synthesise what is known about oral care after stroke, identify knowledge gaps and outline priorities for research that will provide evidence to inform best practice. METHODS: A narrative review from a multidisciplinary perspective, drawing on evidence from systematic reviews, literature, expert and lay opinion to scrutinise current practice in oral care after a stroke and seek consensus on research priorities.Findings: Oral care tends to be of poor quality and delegated to the least qualified members of the caring team. Nursing staff often work in a pressured environment where other aspects of clinical care take priority. Guidelines that exist are based on weak evidence and lack detail about how best to provide oral care. DISCUSSION: Oral health after a stroke is important from a social as well as physical health perspective, yet tends to be neglected. Multidisciplinary research is needed to improve understanding of the complexities associated with delivering good oral care for stroke patients. Also to provide the evidence for practice that will improve wellbeing and may reduce risk of aspiration pneumonia and other serious sequelae. CONCLUSION: Although there is evidence of an association, there is only weak evidence about whether improving oral care reduces risk of pneumonia or mortality after a stroke. Clinically relevant, feasible, cost-effective, evidence-based oral care interventions to improve patient outcomes in stroke care are urgently needed.

Failing to meet the goals of periodontal recall programs. What next?

Supportive periodontal care is a crucial aspect of the management of chronic periodontitis and peri-implantitis and is inevitably a long-term commitment for both the clinician and the patient. The principal goals of supportive care are to achieve a high standard of plaque control, minimize bleeding and maintain pockets at less than 6 mm. Gain of attachment around natural teeth during supportive periodontal care has been reported, although gain of attachment and of bone during supportive care may be a more pragmatic and aspirational aim in the longer term. Furthermore, we occasionally see patients for whom, despite excellent home and professional care (surgical or nonsurgical), including the management of risk factors, supportive periodontal care appears to be failing and therefore for such patients the clinician needs to consider further management options. This review considers, in particular, the options of using local or systemically delivered antimicrobials to eradicate periodontal and peri-implant disease progression and discusses the extent to which culture and sensitivity testing before the prescription of systemically delivered antimicrobials may be a cost-effective alternative to prescribing 'blind'.

Development and feasibility testing of an oral hygiene intervention for stroke unit care.

OBJECTIVE: To develop an oral hygiene complex intervention and evaluate its feasibility in a single UK stroke centre. BACKGROUND: Oral hygiene interventions might improve clinical outcomes after stroke but evidence-based practice is lacking. MATERIALS AND METHODS: We used a sequential mixed methods approach and developed an oral hygiene complex intervention comprising: (i) web-based education and 'hands-on' practical training for stroke unit nursing staff, (ii) a pragmatic oral hygiene protocol consisting of twice-daily powered (or manual if preferred) brushing with chlorhexidine gel (or non-foaming toothpaste) ± denture care. We evaluated feasibility of (i) the staff education and training and (ii) the oral hygiene protocol in consenting inpatients with confirmed stroke, requiring assistance with at least one aspect of personal care. RESULTS: The staff education and training were feasible, acceptable and raised knowledge and awareness. Several barriers to completing the education and training were identified. The oral hygiene protocol was feasible and well-tolerated. 22% of eligible patients screened declined participation in the study. Twenty-nine patients (median age = 78 year; National Institutes of Health Stroke Scale score = 8.5; 73% dentate) were recruited at a median of 7 days from stroke onset. 97% of participants chose the default chlorhexidine-based protocol; the remainder chose the non-foaming toothpaste-based protocol. The mouth hygiene protocol was administered as prescribed on 95% of occasions, over a median duration of 28 days. There were no adverse events attributed to the oral hygiene protocol. CONCLUSION: Our oral hygiene complex intervention was feasible in a single UK stroke centre. Further studies to optimise patient selection, model health economics and explore efficacy are now required.

The impact of structured plaque control for patients with gingival manifestations of oral lichen planus: a randomized controlled study.

AIM: To evaluate the impact of a structured plaque control intervention on clinical and patient-centred outcomes for patients with gingival manifestations of oral lichen planus. MATERIALS AND METHODS: Eighty-two patients were recruited into a 20-week randomized controlled trial. The intervention was structured plaque control comprising powered tooth brushing and inter-dental cleaning advice. Control subjects continued with their normal dental plaque control regimen. The primary outcome measure was the oral health impact profile (OHIP) with secondary outcomes of pain, plaque index, mucosal disease score and cost-effectiveness. RESULTS: Overall, the intervention patients showed statistically significant improvements in OHIP sum ordinal and OHIP dichotomous scores compared with control. There were improvements in the functional limitation, psychological discomfort and physical disability domains at 4- and 20-weeks and in the psychological disability domain at 20-weeks. The intervention was successful in reducing plaque compared to control (p < 0.001) and improvements were observed using the mucosal disease indices at the 4- and 20-week follow-ups (p < 0.001). CONCLUSION: A structured plaque control intervention was effective in improving the oral health-related quality of life and clinically observed gingival lesions. This study provides evidence to include intensive plaque control within patients' initial and on-going management.

Organisation, practice and experiences of mouth hygiene in stroke unit care: a mixed-methods study.

AIMS AND OBJECTIVES: To (1) investigate the organisation, provision and practice of oral care in typical UK stroke units; (2) explore stroke survivors', carers' and healthcare professionals' experiences and perceptions about the barriers and facilitators to receiving and undertaking oral care in stroke units. BACKGROUND: Cerebrovascular disease and oral health are major global health concerns. Little is known about the provision, challenges and practice of oral care in the stroke unit setting, and there are currently no evidence-based practice guidelines. DESIGN: Cross-sectional survey of 11 stroke units across Greater Manchester and descriptive qualitative study using focus groups and semi-structured interviews. METHODS: A self-report questionnaire was used to survey 11 stroke units in Greater Manchester. Data were then collected through two focus groups (n = 10) with healthcare professionals and five semi-structured interviews with stroke survivors and carers. Focus group and interview data were recorded, transcribed verbatim and analysed using framework approach. RESULTS: Eleven stroke units in Greater Manchester responded to the survey. Stroke survivors and carers identified a lack of oral care practice and enablement by healthcare professionals. Healthcare professionals identified a lack of formal training to conduct oral care for stroke patients, inconsistency in the delivery of oral care and no set protocols or use of formal oral assessment tools. CONCLUSION: Oral care post-stroke could be improved by increasing healthcare professionals' awareness, understanding and knowledge of the potential health benefits of oral care post-stroke. Further research is required to develop and evaluate the provision of oral care in stroke care to inform evidence-based education and practice. RELEVANCE TO CLINICAL PRACTICE: Development of staff training and education, and evidence-based oral care protocols may potentially benefit patient care and outcomes and be implemented widely across stroke care.

IQuaD dental trial; improving the quality of dentistry: a multicentre randomised controlled trial comparing oral hygiene advice and periodontal instrumentation for the prevention and management of periodontal disease in dentate adults attending dental primary care.

BACKGROUND: Periodontal disease is the most common oral disease affecting adults, and although it is largely preventable it remains the major cause of poor oral health worldwide. Accumulation of microbial dental plaque is the primary aetiological factor for both periodontal disease and caries. Effective self-care (tooth brushing and interdental aids) for plaque control and removal of risk factors such as calculus, which can only be removed by periodontal instrumentation (PI), are considered necessary to prevent and treat periodontal disease thereby maintaining periodontal health. Despite evidence of an association between sustained, good oral hygiene and a low incidence of periodontal disease and caries in adults there is a lack of strong and reliable evidence to inform clinicians of the relative effectiveness (if any) of different types of Oral Hygiene Advice (OHA). The evidence to inform clinicians of the effectiveness and optimal frequency of PI is also mixed. There is therefore an urgent need to assess the relative effectiveness of OHA and PI in a robust, sufficiently powered randomised controlled trial (RCT) in primary dental care. METHODS/DESIGN: This is a 5 year multi-centre, randomised, open trial with blinded outcome evaluation based in dental primary care in Scotland and the North East of England. Practitioners will recruit 1860 adult patients, with periodontal health, gingivitis or moderate periodontitis (Basic Periodontal Examination Score 0-3). Dental practices will be cluster randomised to provide routine OHA or Personalised OHA. To test the effects of PI each individual patient participant will be randomised to one of three groups: no PI, 6 monthly PI (current practice), or 12 monthly PI.Baseline measures and outcome data (during a three year follow-up) will be assessed through clinical examination, patient questionnaires and NHS databases.The primary outcome measures at 3 year follow up are gingival inflammation/bleeding on probing at the gingival margin; oral hygiene self-efficacy and net benefits. DISCUSSION: IQuaD will provide evidence for the most clinically-effective and cost-effective approach to managing periodontal disease in dentate adults in Primary Care. This will support general dental practitioners and patients in treatment decision making. TRIAL REGISTRATION: Protocol ID: ISRCTN56465715.

Cost-effectiveness of personalized plaque control for managing the gingival manifestations of oral lichen planus: a randomized controlled study.

AIM: To undertake cost-effectiveness and cost-benefit analyses of an intervention to improve oral health in patients presenting with the gingival manifestations of oral lichen planus (OLP). MATERIALS & METHODS: Eighty-two patients were recruited to a 20-week randomized controlled trial. The intervention was personalized plaque control comprising powered tooth brushing and inter-dental cleaning advice. The primary outcome measure was the oral health impact profile (OHIP) with secondary outcomes of pain, plaque index, mucosal disease score and cost-effectiveness. Private cost data and stated willingness-to-pay (WTP) values for treatment were obtained from intervention patients at 20 weeks. RESULTS: Overall, 81% of intervention patients showed improvement in both plaque index and mucosal disease score at 20 weeks compared to 30% of controls that continued with their usual plaque control regimen. All intervention group patients stated a positive WTP value. The mean net value of the treatment was £172 compared to the incremental cost of the treatment estimated at £122.75. The cost-effectiveness analysis resulted in an incremental cost-effectiveness ratio of £13 per OHIP point. CONCLUSIONS: The tailored plaque control programme was more effective than control in treating the gingival manifestations of oral lichen planus. The programme is cost effective for modest values placed on a point on the OHIP scale and patients generally valued the treatment in excess of the cost.
