Regularly attending adult patients are increasingly asymptomatic and not in need of treatment when attending for their routine dental examinations. As oral health improves further, using the general dental practitioner to undertake the “checkup” on regular “low-risk” patients represents a substantial and potentially unnecessary cost for state-funded systems. Given recent regulatory changes in the United Kingdom, it is now theoretically possible to delegate a range of tasks to hygiene-therapists. This has the potential to release the general dental practitioner’s time and increase the capacity to care. The aim of this study is to compare the diagnostic test accuracy of hygiene-therapists when screening for dental caries and periodontal disease in regularly attending asymptomatic adults who attend for their checkup. A visual screen by hygiene-therapists acted as the index test, and the general dental practitioner acted as the reference standard. Consenting asymptomatic adult patients, who were regularly attending patients at 10 practices across the Northwest of England, entered the study. Both sets of clinicians made an assessment of dental caries and periodontal disease. The primary outcomes measured were the sensitivity and specificity values for dental caries and periodontal disease. In total, 1899 patients were screened. The summary point for sensitivity of dental care professionals when screening for caries and periodontal disease was 0.81 (95% CI, 0.74 to 0.87) and 0.89 (0.86 to 0.92), respectively. The summary point for specificity of dental care professionals when screening for caries and periodontal disease was 0.87 (0.78 to 0.92) and 0.75 (0.66 to 0.82), respectively. The results suggest that hygiene-therapists could be used to screen for dental caries and periodontal disease. This has important ramifications for service design in public-funded health systems.

Objectives Role substitution between primary care dentists (PCDs) and dental hygienists and therapists is increasingly being used in a number of different countries. Opponents to this development argue that it is unsafe and frequently cite the potential for missing oral malignancy as an inherent danger. The aim of the present study was to determine the comparative diagnostic test accuracy of different members of the dental team when differentiating between standardised photographs of mouth cancer, potentially malignant disorders and benign oral lesions.Methods A total of 192 dental professionals, comprising 96 PCDs, 63 DH-Ts, nine hospital-based dental staff and 24 other dental professionals were sampled purposively. Following orientation, participants were asked to score 90 clinical photographs that depicted cases of oral squamous cell carcinoma, potentially malignant disorders and non-malignant lesions of the oral mucosa. For each photograph participants were asked to determine whether they felt the lesion was representative of carcinoma, a potentially malignant disorder (test positive), or whether the lesion was benign (test negative). They were also asked to record their confidence in their decision on a 0–10 scale. Judgement decisions were compared against the known histopathological diagnosis of each lesion. Sensitivity and specificity were calculated for each participant and clinical group.Results The diagnostic test accuracy of PCDs and DH-Ts was similar. There was a median sensitivity of 81% Interquartile range (IQR) 19%) for PCDs and 77% (IQR 19%) for DH-T, with specificity of 73% (IQR 16%) and 69% (IQR 17%) respectively. DH-Ts missed fewer frank malignant lesions compared to PCDs.Conclusion The performance of PCDs and DH-Ts when differentiating between mouth cancer, potentially malignant disorders and benign lesions is comparable. DH-Ts should be regarded as being as competent as PCDs as front-line healthcare workers with regard to detection of mouth cancer. However, considerable heterogeneity in detection was found within both clinical groups, suggesting that training remains paramount.

Skill-mix in preventive dental practice - will it help address need in the future?

Paul Brocklehurst; Richard Macey

BackgroundPopulation health needs are changing. The levels of dental caries and periodontal disease across the population as a whole is falling. The proportion of adults with a functional dentition in many developed countries has increased substantially and edentulous rates have dropped to some of their lowest levels. Despite this, a pronounced social gradient still exists, many adults do not attend dental services regularly and disease in young children remains intransigent amongst the poorest. New challenges are emerging too as the growing number of older people, above sixty-five years of age, retain their teeth.MethodsEnsuring “the right number of people with the right skills are in the right place at the right time to provide the right services to the right people” is critical for future dental service provision, both to meet the new challenges ahead and to ensure future services are cost-effective, efficient and reduce health-inequalities. Greater use of “skill-mix” models could have a substantial role in the future, as dentistry moves from a “cure” to a “care” culture.DiscussionThe provision of dental services in many countries currently adopts a “one-size-fits-all”, where the dentist is the main care-giver and the emphasis is on intervention. As needs change in the future, the whole of the dental team should be utilised to deliver primary, secondary and tertiary prevention in an integrated model. Growing evidence suggests that other members of the dental team are effective in providing care, but introducing this paradigm shift is not without its challenges. The provision of incentives within funding systems and social acceptability are amongst the key determinants in producing a service that is responsive to need, improves access and delivers equity.

Feasibility study: assessing the efficacy and social acceptability of using dental hygienist-therapists as front-line clinicians

Richard Macey; Anne-Marie Glenny; Paul Brocklehurst

Background The oral health of the adult population has been improving in the United Kingdom decade upon decade. Over half of dental service activity in the National Health Service (NHS) is limited to a check-up without any further treatment. This raises a question as to whether check-ups could be provided by dental hygienist-therapists, rather than general dental practitioners. The aim of this study was to assess the feasibility of a definitive trial to evaluate the costs and effects of using dental hygienist-therapists to undertake the check-up.Methods/design Adult NHS patients were randomised into three arms in two dental practices: patients who only saw dental hygienist-therapists for a check-up, those that saw the general dental practitioner and dental hygienist-therapist alternatively and a control, where patients only saw the general dental practitioner for their check-up. The study ran for 15 months. The primary outcome measures of the study were patient recruitment, retention and fidelity. A parallel and embedded qualitative study was undertaken which recorded the views of participating patients to determine the social acceptability of the intervention.Results Sixty patients participated in the study. The initial recruitment rate for the study was 33.7%. This figure increased to over 82.1% when telephone calls or face-to-face recruitment was utilised. The retention rates were 60% for both the dental hygienist-therapist only group and the alternate general dental practitioner and dental hygienist-therapist group, compared to 70% for the general dental practitioner only group. Fifteen patients were interviewed in the qualitative study and supported a team approach to the provision of check-ups in the NHS. Conclusion This study demonstrates the feasibility of a definitive trial to evaluate the costs and effects of using dental-hygienist-therapists to undertake the check-up.

BackgroundThis paper is a summary document of the Prevention in Practice Conference and Special Supplement of BMC Oral Health. It represents the consensus view of the presenters and captures the questions, comments and suggestions of the assembled audience.MethodsUsing the prepared manuscripts for the conference, collected materials from scribes during the conference and additional resources collated in advance of the meeting, authors agreed on the summary document.ResultsThe Prevention in Practice conference aimed to collate information about which diseases could be prevented in practice, how diseases could be identified early enough to facilitate prevention, what evidence based therapies and treatments were available and how, given the collective evidence, could these be introduced in general dental practice within different reimbursement models.ConclusionsWhile examples of best practice were provided from both social care and insurance models it was clear that further work was required on both provider and payer side to ensure that evidence based prevention was both implemented properly but also reimbursed sufficiently. It is clear that savings can be made but these must not be overstated and that the use of effective skill mix would be key to realizing efficiencies. The evidence base for prevention of caries and periodontal disease has been available for many years, as have the tools and techniques to detect, diagnose and stage the diseases appropriately. Dentistry finds itself in a enviable position with respect to its ability to prevent, arrest and reverse much of the burden of disease, however, it is clear that the infrastructure within primary care must be changed, and practitioners and their teams appropriately supported to deliver this paradigm shift from a surgical to a medical model.
