As we are all too aware, severe periodontal diseases are estimated to affect around 14% of the global adult population, representing more than one billion cases worldwide. 1 Periodontitis is currently the 6th most prevalent disease globally. 2 Dental hygienists are trained to screen, and treat periodontal diseases: their contribution to the provision of oral healthcare and prevention of disease is considerable

Background: The first case of coronavirus disease 2019 (COVID-19) was identified in Wuhan, China in December 2019, as a highly contagious infection transmitted via droplets, and person-to-person contact. Airborne and aerosol transmission have also been implicated. Aerosol generating procedures such as scaling and polishing may increase the risk for developing COVID-19 in dental clinics, and may thus place some psychological strain on dental therapists. This study aimed to determine the psychosocial effect of COVID-19 on dental therapists in Nigeria. Materials and Methods: This cross-sectional study was carried out following ethical approval from the institutional Ethics Committee. Data collection was through self-administered online questionnaires and included socio-demographic characteristics. Psychosocial well-being was assessed using a five-point Likert scale that assessed the level of worry. Scores were summed up to obtain the mean (range 5–25). Statistical significance was set at a level of P ≤ 0.05. Results: The 192 respondents had a mean age of 28.0 ± 7.2 years, 96.9% were aware of COVID-19. Sixteen (8.3%) participants reported at least one medical condition. The mean psychosocial-wellbeing score was 18.4 ± 4.9. Most (90.1%) were worried about the COVID-19 pandemic, while 76% were severely worried about getting infected with COVID-19 in the dental clinic, and 72.9% were severely worried about the availability of personal protective equipment (PPE) in the clinic. Participants with self-reported medical conditions had a slightly higher psychosocial score (18.6 vs. 18.4), but this was not significant (P = 0.902). Conclusion: The psychosocial effect of the COVID-19 pandemic was considerable on the dental therapists. The provision of PPE, training on Infection Prevention and Control, and psychosocial support will reduce the psychosocial effect of COVID-19 on dental therapists in Nigeria as they are willing to ensure patients' safety.

Supplemental Digital Content is available in the text., Background: Dental therapists (DTs) are primary care dental providers, used globally, and were introduced in the United States (US) in 2005. DTs have now been adopted in 13 states and several Tribal nations. Objectives: The objective of this study is to qualitatively examine the drivers and outcomes of the US dental therapy movement through a health equity lens, including community engagement, implementation and dissemination, and access to oral health care. Methods: The study compiled a comprehensive document library on the dental therapy movement including literature, grant documents, media and press, and gray literature. Key stakeholder interviews were conducted across the spectrum of engagement in the movement. Dedoose software was used for qualitative coding. Themes were assessed within a holistic model of oral health equity. Findings: Health equity is a driving force for dental therapy adoption. Community engagement has been evident in diverse statewide coalitions. National accreditation standards for education programs that can be deployed in 3 years without an advanced degree reduces educational barriers for improving workforce diversity. Safe, high-quality care, improvements in access, and patient acceptability have been well documented for DTs in practice. Conclusion: Having firmly taken root politically, the impact of the dental therapy movement in the US, and the long-term health impacts, will depend on the path of implementation and a sustained commitment to the health equity principle.

Background Many dental ‘check-ups’ in the NHS result in no further treatment. The patient is examined by a dentist and returned to the recall list for a further check-up, commonly in 6 or 12 months’ time. As the oral health of regular dental attenders continues to improve, it is likely that an increasing number of these patients will be low risk and will require only a simple check-up in the future, with no further treatment. This care could be delivered by dental therapists. In 2013, the body responsible for regulating the dental profession, the General Dental Council, ruled that dental therapists could see patients directly and undertake check-ups and routine dental treatments (e.g. fillings). Using dental therapists to undertake check-ups on low-risk patients could help free resources to meet the future challenges for NHS dentistry. Objectives The objectives were to determine the most appropriate design for a definitive study, the most appropriate primary outcome measure and recruitment and retention rates, and the non-inferiority margin. We also undertook a realist-informed process evaluation and rehearsed the health economic data collection tool and analysis. Design A pilot randomised controlled trial over a 15-month period, with a realist-informed process evaluation. In parallel, we rehearsed the health economic evaluation and explored patients’ preferences to inform a preference elicitation exercise for a definitive study. Setting The setting was NHS dental practices in North West England. Participants A total of 217 low-risk patients in eight high-street dental practices participated. Interventions The current practice of using dentists to provide NHS dental check-ups (treatment as usual; the control arm) was compared with using dental therapists to provide NHS dental check-ups (the intervention arm). Main outcome measure The main outcome measure was difference in the proportion of sites with bleeding on probing among low-risk patients. We also recorded the number of ‘cross-over’ referrals between dentists and dental therapists. Results No differences were found in the health status of patients over the 15 months of the pilot trial, suggesting that non-inferiority is the most appropriate design. However, bleeding on probing suffered from ‘floor effects’ among low-risk patients, and recruitment rates were moderately low (39.7%), which suggests that an experimental design might not be the most appropriate. The theory areas that emerged from the realist-informed process evaluation were contractual, regulatory, institutional logistics, patients’ experience and logistics. The economic evaluation was rehearsed and estimates of cost-effectiveness made; potential attributes and levels that can form the basis of preference elicitation work in a definitive study were determined. Limitations The pilot was conducted over a 15-month period only, and bleeding on probing appeared to have floor effects. The number of participating dental practices was a limitation and the recruitment rate was moderate. Conclusions Non-inferiority, floor effects and moderate recruitment rates suggest that a randomised controlled trial might not be the best evaluative design for a definitive study in this population. The process evaluation identified multiple barriers to the use of dental therapists in ‘high-street’ practices and added real value. Future work Quasi-experimental designs may offer more promise for a definitive study alongside further realist evaluation. Trial registration Current Controlled Trials ISRCTN70032696.

The Preschool Oral Healthcare Programme (POHP) was introduced in Malaysia by the Ministry of Health in 1984 to provide oral healthcare for 5&ndash, 6-year-old children. Most of its evaluations were directed towards assessing children&rsquo, s oral health status. Little emphasis has been placed on assessing the programme feasibility from the perspectives of the oral health personnel. The objective of the study was to explore the facilitators and barriers to the implementation of the POHP using the perspectives of dental therapists (DT) in Selangor state, Malaysia. This study took a qualitative approach using focus group discussion (FGD) as the data collection method. The data were transcribed verbatim followed by thematic analysis using Nvivo software. A total of 13 FGDs had been conducted involving 114 DT. The main facilitators were good dental teamwork, assistance from schools and teachers, sufficient training of DT, adequate support from dental administration, and good cooperation from the children. The main barriers were lack of financial support, manpower, time, inadequate support from preschools and children, language barrier, and accessibility to sugary food and drinks at schools. The study provided important insights regarding the POHP that would be useful for programme improvement through policy changes, workforce training, and enhanced school participation.

Background In Sierra Leone (SL), a low-income country in West Africa, dental care is very limited, largely private, and with services focused in the capital Freetown. There is no formal dental education. Ten dentists supported by a similar number of dental care professionals (DCPs) serve a population of over 7.5 million people. The objective of this research was to estimate needs-led requirements for dental care and human resources for oral health to inform capacity building, based on a national survey of oral health in SL. Methods A dedicated operational research (OR) decision tool was constructed in Microsoft Excel to support this project. First, total treatment needs were estimated from our national epidemiological survey data for three key ages (6, 12 and 15 years), collected using the ‘International Caries Classification and Management System (ICCMS)’ tool. Second, oral health needs were extrapolated to whole population levels for each year-group, based on census demographic data. Third, full time equivalent (FTE) workforce capacity needs were estimated for mid-level providers in the form of Dental Therapists (DTs) and non-dental personnel based on current oral disease management approaches and clinical timings for treatment procedures. Fourth, informed by an expert panel, three oral disease management scenarios were explored for the national population: (1) Conventional care (CC): comprising oral health promotion (including prevention), restorations and tooth extraction; (2) Surgical and Preventive care (S5&6P and S6P): comprising oral health promotion (inc. prevention) and tooth extraction (D5 and D6 together, & at D6 level only); and (3) Prevention only (P): consisting of oral health promotion (inc. prevention). Fifth, the findings were extrapolated to the whole population based on demography, assuming similar levels of treatment need. Results To meet the needs of a single year-group of childrens’ needs, an average of 163 DTs (range: 133–188) would be required to deliver Conventional care (CC); 39 DTs (range: 30–45) to deliver basic Surgical and Preventive care (S6P); 54 DTs for more extended Surgical and Preventive care (S5&6P) (range 38–68); and 27 DTs (range: 25–32) to deliver Prevention only (P). When scaled up to the total population, an estimated 6,147 DTs (range: 5,565–6,870) would be required to deliver Conventional care (CC); 1,413 DTs (range: 1255–1438 DTs) to deliver basic Surgical and Preventive care (S6P); 2,000 DTs (range 1590–2236) for more extended Surgical and Preventive care (S5&6P) (range 1590–2236); and 1,028 DTs to deliver Prevention only (P) (range: 1016–1046). Furthermore, if oral health promotion activities, including individualised prevention, could be delivered by non-dental personnel, then the remaining surgical care could be delivered by 385 DTs (range: 251–488) for the S6P scenario which was deemed as the minimum basic baseline service involving extracting all teeth with extensive caries into dentine. More realistically, 972 DTs (range: 586–1179) would be needed for the S5&6P scenario in which all teeth with distinctive and extensive caries into dentine are extracted. Conclusion The study demonstrates the huge dental workforce needs required to deliver even minimal oral health care to the Sierra Leone population. The gap between the current workforce and the oral health needs of the population is stark and requires urgent action. The study also demonstrates the potential for contemporary epidemiological tools to predict dental treatment needs and inform workforce capacity building in a low-income country, exploring a range of solutions involving mid-level providers and non-dental personnel.

This special issue on practice management represents a labor of love from some of the key thinkers/leaders in the field of dental practice management in the United States. The topics covered in the articles are current and, in some cases, somewhat controversial. I hope the readers find the articles both stimulating and insightful.

Background Dental Therapists and Oral Health Therapists (Therapists) working in the New South Wales (NSW) Public Oral Health Service are charged with providing clinical dental treatment including preventive care for all children under 18 years of age. Adolescents in particular are at risk of dental caries and periodontal disease which may be controlled through health education and clinical preventive interventions. However, there is a dearth of evidence about the type or the proportion of clinical time allocated to preventive care. The aim of this study is to record the proportion and type of preventive care and clinical treatment activities provided by Therapists to adolescents accessing the NSW Public Oral Health Service. Methods Clinical dental activity data for adolescents was obtained from the NSW Health electronic Information System for Oral Health (ISOH) for the year 2011. Clinical activities of Therapists were examined in relation to the provision of different types of preventive care for adolescents by interrogating state-wide public oral health data stored on ISOH. Results Therapists were responsible for 79.7 percent of the preventive care and 83.0 percent of the restorative treatment offered to adolescents accessing Public Oral Health Services over the one year period. Preventive care provided by Therapists for adolescents varied across Local Health Districts ranging from 32.0 percent to 55.8 percent of their clinical activity. Conclusions Therapists provided the majority of clinical care to adolescents accessing NSW Public Oral Health Services. The proportion of time spent undertaking prevention varied widely between Local Health Districts. The reasons for this variation require further investigation.

New models in the delivery of healthcare such as mobile clinics, retail clinics, and telehealth have helped to bring care to patients who might not otherwise receive care due to geographic limitations. Such alternatives may help to address the need for dental care in rural communities in the United States. In addition to these solutions, dental therapists can increase the available provider base to deliver preventative dental services to children.
