Objective: To assess the knowledge, attitude, and practice of Dutch dentists on oral leukoplakia (OL) and to what extent these aspects are related to whether or not dentists regularly monitor patients with OL., Material and Methods: A self-developed questionnaire was distributed via a web survey among a sample of dentists participating in an intervision program. Of 1626 invited dentists, 437 (26.9%) answered the questionnaire; 52.6% were females and 47.4% males, 36.4% were 44 years or younger, 24.0% were 45 to 54 years old and 39.6% were 55 years or older, 94.1% were general dental practitioners, 60.2% were practice owners, and 49.9% work more than 31 hours per week., Results: In total, 57.0% performed regular follow-up of patients with OL. Compared to dentists who do not perform regular follow-up of patients with OL, those who do were more confident in performing control, were more likely to be practice owners, checked a greater number of oral subsites during dental check-ups, had encountered more cases of suspected oral cancer among their own patients, and were more likely to implement effective policies when faced with mucosal lesions without a clear diagnosis. The vast majority of all participants indicated that their knowledge about oral mucosal diseases, OL, and oral cancer is limited. Just over half reported receiving insufficient education on these topics during their dental study., Conclusions: It seems that interested dentists who have an affinity for oral mucosal diseases can properly fulfil the controlling and detecting role on selected patients with OL. Additional education on various aspects of OL is required., Clinical Relevance: In the Netherlands, interested dentists can responsibly follow up on a large proportion of patients with OL., Competing Interests: Conflict of interest None disclosed., (Copyright © 2024 The Authors.

Background: Nondental factors (ie, financial, psychological, or cultural considerations) can play a role in extraction requests. The purpose of this study was to investigate whether patients' perspectives on extraction without a valid clinical indication align with those of practitioners., Methods: Dentists from 3 centers for special oral health care, oral and maxillofacial surgeons (OMFS) from 3 hospitals in the Netherlands, and their patients participated in this prospective observational study. Patients 18 years and older who requested extraction of permanent teeth other than third molars were included. Patients, dentists, and OMFS completed questionnaires., Results: A total of 21 dentists and 20 OMFS participated in this study. Among 192 dental patients and 572 patients from OMFS, patients reported nondental reasons more often (7.1% of dental patients, 3.5% of OMFS patients) than professionals (1.6% of dentists, 1.7% of OMFS). Of all extraction requests, 96.4% were granted. Extraction was not performed if both practitioner and patient cited only nondental reasons., Conclusions: Although dentists and OMFS received few requests for extraction on purely nondental grounds, patients were more likely to report extractions driven solely by nondental factors than practitioners., Practical Implications: The absence of extractions executed purely on nondental grounds is a reassuring finding, as it dovetails with the ethical principles that dental care professionals must adhere to., Competing Interests: Disclosures None of the authors reported any disclosures., (Copyright © 2025 American Dental Association.

The number of elderly people worldwide and their need for dental care increases in a yearly basis. A dental practice website can be a valuable source of information to these patients that may need comprehensive or adjusted care. Therefore, this study aimed to evaluate the information on Dutch general dental practice websites on topics relevant to the treatment of (frail) elderly patients. Websites were selected from (1) a random sample of 217 Dutch general dental practices (sample-group) and (2) dental practices of 130 members of the Dutch Association for Gerodontology (gero-group), and screened for items in 4 categories: website functionality, contact details and accessibility, composition of the dental team, and specific information for elderly patients. Of the selected websites, 196 in the sample-group and 54 in the gero-group were eligible for data collection. Most websites mentioned opening hours, a phone number, and the composition of the dental team. Other information was overall scarce, especially regarding (frail) elderly patients. The gero-group significantly more often mentioned elderly as a specific target patient group (11,1% vs 2,6%), but numbers were overall low. Websites in the gero-group were hardly more informative or adjusted to elderly than in the sample-group; wheelchair accessibility was the only feature mentioned significantly more often (37.0% vs 17.3%). Only one website in the sample-group and 2 websites in the gero-group mentioned the possibility of home visits. In conclusion, dental practice websites lack information in general, and information relevant to elderly patients in particular, and there is room for improvement in website functionality. Additionally, general dental practices seem insufficiently equipped for the treatment of (frail) elderly patients, highlighting the need for improvement of oral healthcare for this specific patient group. This study addresses the insufficiencies in the provision of information on dental practice websites, allowing for targeted future studies towards improvement., Competing Interests: Conflict of interest None disclosed., (Copyright © 2024 The Authors.

In January 2021, the guideline 'Periodontal screening, diagnosis, and treatment in general practice' was introduced as a successor to the so-called paro protocol. Simultaneously, the Dutch Periodontal Screening Index was replaced by the Periodic Periodontal Screening. The experiences of general dental practitioners and dental hygienists with the new guideline were evaluated in the autumn of 2022. Random groups of 1,000 general dental practitioners and 400 dental hygienists were invited to answer an online questionnaire on this topic: 125 (12.5%) general dental practitioners and 102 (25.5%) dental hygienists responded. By the end of 2022, a large majority of both groups were using the Periodic Periodontal Screening. Both professional groups were satisfied with the new guideline. Dental hygienists used the Periodic Periodontal Screening in more cases than general dental practitioners and were also more frequently satisfied with the new guideline. Both oral healthcare professionals believed that the Periodic Periodontal Screening offers better opportunities to involve the patient in periodontal care compared to the Dutch Periodontal Screening Index.

Background: Patient adherence is a key factor in achieving orthodontic success. While in recent years there have been changes in orthodontic healthcare, no recent comprehensive reviews regarding adherence in orthodontics are available. Therefore, the aim of this planned scoping review is to systematically map the available literature regarding patient adherence in orthodontics to identify factors associated with patient adherence and to investigate if there are knowledge gaps in the available literature., Methods/design: This protocol was drafted according to guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P) statement and the PRISMA extension for Scoping Reviews (PRISMA-ScR). For the methods Arksey and O'Malley's framework and the Reviewer's Manual of the Joanna Briggs Institute for conducting scoping reviews were consulted. The inclusion criteria for this scoping review are studies of all designs assessing any form of adherence in orthodontics, published in English from 2006 onwards. The exclusion criteria are studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist's recommendations and advice, those with oral cleft and craniofacial conditions, and those solely treated for obstructive sleep apnoea. Case reports and studies published in non peer reviewed journals will also be excluded. The following electronic databases will be searched: Embase, PubMed, and Web of Science Core Collection. The following key terms will be used in the search strategies: 'treatment adherence and compliance', and 'orthodontics'. Multiple reviewers will independently screen the results and perform the data charting process. A narrative description will be provided for the analysis of the included studies. The results will be categorized into multiple topics based on recommendations by previous studies into patient adherence. Identified knowledge gaps will be reported and recommendations for future research will be suggested., Discussion: No systematic review has previously assessed this exact topic. Because of the broad-spectrum research questions and the expected widely scattered literature a scoping review approach was chosen over a systematic review approach. The Academic Centre for Dentistry Amsterdam (ACTA) has been conducting research in patient adherence in orthodontics up to 2006 and therefore only studies published from 2006 onwards will be researched in this review. Identifying knowledge gaps and summarizing and disseminating research findings on this topic is important for every dental professional performing orthodontic treatment.

Background: Patient adherence is a key factor in achieving orthodontic treatment success. Despite an evolution in orthodontic healthcare, no recent comprehensive reviews are available on patient adherence in orthodontics. This scoping review provides an evidence-based overview of the literature available on multiple aspects of patient adherence in orthodontics, during both active treatment as well as during the retention phase. Knowledge gaps identified in the literature are listed., Methods: The protocol for this scoping review was registered in the Open Science Framework ( https://doi.org/10.17605/OSF.IO/EC6QD ). Electronic databases and reference lists of relevant studies were searched up to 9 February 2023. The inclusion criteria were studies investigating any form of patient adherence in orthodontics published in English from 2006 onwards. The exclusion criteria were studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist's recommendations and advice, those with oral cleft and craniofacial conditions, and those treated solely for obstructive sleep apnoea. Non-peer-reviewed studies and case reports were also excluded., Results: A total of 3284 articles were identified, 60 of which met the criteria for final inclusion., Conclusions: There is no conclusive evidence on which factors have a significant impact on patient adherence and how patient adherence can be promoted. The degree of patient adherence is generally not compared to achieved treatment results or stability of treatment results, making it difficult to provide clear statements about the impact of the degree of adherence on desired treatment results or orthodontic stability., (© 2024.

Aims: To outline the extent to which practice owners in Dutch oral healthcare practices (OHPs) use a directive and supportive leadership styles, to map out which goals practice owners in Dutch OHPs consider most important when choosing collaboration within the practice and to identify the reasons why oral healthcare professionals choose to engage in collaborative practice., Materials and Methods: A survey involving 802 general dental practitioners, dental hygienists, and prevention assistants was conducted. The questionnaire covered, among other subjects, leadership styles and reasons for collaboration. Data analysis included descriptive statistics, chi-square tests, one-way ANOVA, linear regression, and logistic regression., Results: Compared to employees, practice owners ascribe to themselves more characteristics of both directive and supportive leadership. The most frequently mentioned reasons for choosing a practice form that involves collaboration were the possibilities to provide the best care and the desire to focus on prevention. Healthcare providers chose to work in a collaborative practice for several reasons, which were associated with profession, age and gender., Conclusions: The degree of directive and supportive leadership among practice owners in dental care practices in the Netherlands showed a strong correlation. The most frequently mentioned reasons for choosing collaboration were related to healthcare content., (© 2024. The Author(s).)

An important way to manage noncommunicable diseases (NCDs) is to focus on prevention, early detection, and reducing associated risk factors. Risk factors can be detected with simple general health checks, which can also be performed in dental clinics. The purpose of this study was to investigate participants' willingness to participate in general health checks at the dentist, in particular the difference in opinion between medical patients and random healthy dental attendees. A total of 100 medical patients from an outpatient internal medicine clinic and 100 dental clinic attendees were included (total of 200 participants). The participants were asked for their opinion using six closed-ended questions. Overall, 91.0% of participants were receptive to information about the risk of diabetes mellitus (DM) and cardiovascular diseases (CVD). The majority (80-90%) was receptive to screening for DM and CVD risk, such as weight and height measurements, blood pressure measurement, saliva testing for CVD and to measure glucose and cholesterol via finger stick. No significant differences were found in the frequencies of the responses between the different groups based on health status, age, sex, or cultural background. This study shows that most participants are willing to undergo medical screening at the dentist for early detection and/or prevention of common NCDs.

Introduction: The curriculum of the three dental schools in the Netherlands consists of a three-year bachelor's and three-year master's course. The education programmes focus inter alia on clinical dental reasoning, thinking and acting scientifically, general oral healthcare activities, and communication and (inter)professional cooperation. This study examined how recently graduated dentists, in the light of their work experience, evaluate their education in retrospect., Materials and Methods: All 1074 dentists who graduated between 2012 and mid-2017 were invited by e-mail to answer a web survey. Of those, 314 (29%) took part in the study., Results: The majority of dentists were positive about their knowledge of general and clinical oral healthcare fields when they graduated (70% and 68%, respectively). Fewer dentists were satisfied with their skills in terms of some specific procedures (50%) and clinical professional areas (33%). By far, the majority (85%) were satisfied with the educational skills of their teachers. The majority (70%) felt that their education fitted in well with their professional practice. Nevertheless, 60% thought a year's trainee work experience would be a good idea. The overall evaluation of dentists who have their own practices was less positive than those who do not., Conclusion: Knowledge and skills relating to managing a practice were not sufficiently addressed in the programme. The introduction of a practical internship would be desirable, preferably during the education. But when they look back, the majority of recently graduated dentists in the Netherlands are generally positive about the education they received., (© 2022 John Wiley & Sons A/S.

Objectives: This study pertains to a secondary data analysis aimed at determining differences between oral and maxillofacial surgeons (OMFSs) and dentists handling dental extractions without an evident clinical indication., Study Design: A survey of 18 questions was conducted among 256 OMFSs in the Netherlands and a random sample of 800 dentists Respondents could answer the questions in writing or online. The data was collected in the period from November 2019 to January 2020, during which two reminders were sent. Analysis of the data took place via descriptive statistics and Chi Square test., Results: The response rate was 28.1% (n = 72) for OMFSs and 30.3% (n = 242) for dentists. In the past three years, 81.9% (n = 59) of the OMFSs and 68.0% (n = 164) of the dentists received a request for extraction without a clinical indication. The most common reasons were financial and severe dental fear (OMFSs: 64.9 and 50.9% vs dentists: 77.4 and 36.5%). Dentists were significantly more likely (75.6%, n = 114) than OMFS (60.7%, n = 34) to comply with their last extraction request without a clinical indication. Almost none of them regretted the extraction afterwards. As for the request itself, it was found that 17.5% (n = 10) of the OMFSs and 12.5% (n = 20) of the dentists did not check for patients' mental competency (p = 0.352)., Conclusions: Given that most of the interviewed dental professionals complied with non-dental extraction requests when such extractions are ethically and legally precarious, recommendations for handling such requests are greatly needed., Competing Interests: The authors whose names are listed certify that they have no affiliations with or involvement in any organization or entity with any financial interest (such as honoraria; educational grants; participation in speakers’ bureaus; membership, employment, consultancies, stock ownership, or other equity interest; and expert testimony or patent-licensing arrangements), or non-financial interest (such as personal or professional relationships, affiliations, knowledge or beliefs) in the subject matter or materials discussed in this manuscript., (Copyright: © 2023 Broers et al.

Objective: This scoping review aims to identify complex health interventions (CHI's) to prevent early childhood caries (ECC), explore the level of complexity of the identified CHI's, and explore the details of their development, evaluation, and implementation., Introduction: Many interventions to prevent ECC have multiple interacting components and can be seen as CHI's. Recent reviews on these interventions have found inconclusive effects, which may be due to differences in the development, evaluation, and implementation of CHI's., Inclusion Criteria: This scoping review will consider clinical trials reporting CHI's to prevent ECC that starts during pregnancy or in the first year of life. Studies in the English language will be included regardless of the country of origin, sociocultural setting, or context., Methods: This review will follow the Joanna Briggs Institute methodology for scoping reviews. An initial search of PubMed identified keywords and Medical Subject Headings terms. A second search of PubMed, Embase, Clarivate Analytics/Web of Science Core Collection, ClinicalTrials.gov, and the Wiley/Cochrane Library will follow. Two independent reviewers will perform title and abstract screening, retrieve and review full-text studies, and extract data. The reference lists of all included sources will be screened for additional CHI's or relevant publications about a specific CHI. Data charting will be utilised based on study characteristics and intervention complexity. A 39-item instrument will be used to explore the details in the description of the CHI's development, evaluation, and implementation. The results will be presented in tables, visual outputs, and a narrative summary in response to the review questions., Discussion: The proposed review will generate evidence which may provide a direction for the future design of studies on CHI's to prevent ECC and more complete information for those who want to adopt successful interventions to prevent ECC., Competing Interests: The authors have declared that no competing interests exist.

Objective: Transmission of SARS-CoV-2 during oral health care is potentially increased compared to regular social activities. Specific amendments to the Dutch national infection control guidelines were promulgated. This study aimed to map the impact of the coronavirus pandemic on providing oral health care during the first wave of the coronavirus pandemic in 2020 in the Netherlands., Methods: A cross-sectional web-based survey was sent via email to a representative sample of dental hygienists and dentists in the Netherlands., Results: Of the 1700 oral health care practitioners approached, 440 (25.9%) responded to the survey. Patient access to oral health care was severely restricted during the lockdown in the spring of 2020. A total of 1.6% of the oral health care practitioners had laboratory-confirmed COVID-19 during the study period, although this is likely to be an underrepresentation due to limited access to testing at that time. Over half of the participants perceived an increased risk of virus transmission during aerosol-generating treatments in their practices. A large majority (65.0%-87.1%) of the oral health care practitioners followed the COVID-19-specific amendments to the national infection control guidelines. Compared to the pre-pandemic period, additional personal protective equipment and protocols were applied. Factors related with compliance with the additional recommendations were age, employment status, and occupation., Conclusions: The pandemic had a profound impact on both the accessibility and practice of oral health care. This survey study found that most Dutch oral health care practitioners paid extra attention to hygiene and infection control. Also, a low number of COVID-19 infections detected amongst Dutch oral health care practitioners was reported in the Netherlands. These overall outcomes suggest that safe oral health care can be provided when following the current infection control recommendations., (Copyright © 2021 The Authors. Published by Elsevier Inc.

Background: The purpose of this study was to determine how often dental patients request extraction for nondental reasons and how dentists handle such requests., Methods: The authors conducted a survey among 800 Dutch dentists from November 17, 2019, through January 5, 2020. The questionnaire contained 17 items, including a hypothetical case vingette., Results: A total of 242 dentists responded to the survey (response rate was 30.3%, 48.3% of respondents were women, and mean [standard deviation] age was 45.3 [11.8] years). Sixty-eight percent of respondents reported that they had been confronted with a request for extraction on nondental grounds in the past 3 years. One-half of these dentists received such a request 5 times or fewer, 21.3% received such a request 6 through 10 times, 11.3% received such a request 11 through 20 times, and 8.8% received such a request 21 through 30 times. Their most recent request concerned a financial reason (49.7%), a combination of psychological and financial reasons (27.7%), a psychological reason (18.2%), or another reason (4.4%). Most dentists (87.5%) evaluated the patient's competency to make health care decisions. Of all nondental extraction requests, 75.6% (n = 114) were granted. Only 4.0% (n = 6) of the dentists regretted the extraction. Most dentists (82.0%, n = 191) would have refused the extraction in the hypothetical case vignette., Conclusions: Nondental requests for extraction are relatively common. Although dentists are reluctant in theory, they are likely to grant such requests in everyday practice, particularly if the patient cannot afford an indicated conservative treatment., Practical Implications: Dentists should keep in mind that they cannot ethically or legally be required to perform an intervention deemed harmful, even if an autonomous patient made the request., (Copyright © 2022 American Dental Association.

Background: Influenced by governmental measures, collaboration in oral health care practices in the Netherlands has increased in recent decades. Previous studies on this subject have mainly concerned the composition of the staff or have been normative rather than descriptive. Based on the existing literature, four aspects were expected to be of significant influence on the collaboration on oral health care practices: goals, leadership, the allocation of tasks and responsibilities and formalization., Methods: The aim of this study was to describe a classification of collaboration between general dental practitioners and dental hygienists within oral health care practices in the Netherlands. Eighteen semi-structured face-to-face interviews were conducted in nine oral health care practices, which differed with regard to both practice characteristics and characteristics of the principal general dental practitioner. In all practices, the principal general dental practitioner and one dental hygienist were consulted. The interviews were conducted in the practices of the respondents and were held between October 2019 and July 2020. The interviews were analyzed through theoretical thematic analysis using Microsoft Word 2010 and Atlas.ti 8. Three researchers coded and analyzed three practices, and discussed their results. Based on their mutual conclusions, one researcher analysed all practices. The final results were reviewed and approved by the other two researchers., Results: Different factors influencing the collaboration between general dental practitioners and dental hygienist in the Netherlands were found. The most important factors seemed to be leadership style and goals for collaboration. Leadership style varied from very directive to very supportive and seemed to be connected to the allocation of responsibilities. Goals for collaboration varied from predominantly patient-related to mostly practice-related. Formalization appeared to be more present in larger practices and practices that are affiliated to a dental chain., Conclusions: Based on leadership style and goals for collaboration, a classification was identified. This classification is recommended as a starting point for further research on directive and supportive leadership in oral health care practices., (© 2022. The Author(s).)

Background: Research into oral health care for older people has shown that dental care in general decreases with increasing age and frailty and, therefore, oral health care provision may be complex. The aim of this study is to identify the oral health care dentists provide to community-dwelling older people and which barriers they experience in doing this., Methods: In this cross-sectional study, a representative sample of dentists in the Netherlands was asked to prospectively select one older patient and describe this patient using a specially developed registration form; the patient was requested to fill out a questionnaire. The relationship between experienced barriers in providing oral health care to older patients and characteristics of the dentists and the patients was studied by means univariate and multivariate logistic regression analysis., Results: In total, 923 dentists were asked to participate in the study. Data were available for 39.4% dentist-patient pairs. In most cases (87.4%), oral health care was focussed on conservation of the dentition. In all, 14.0% of the dentists experienced barriers in providing oral health care for older people. Some patient factors increase the risk of experiencing barriers, eg, the more difficult behaviour of older patients and the greater disease burden., Conclusions: Oral health care was mostly focussed on conservation of the dentition, and dentists especially experience barriers in oral health provision to older patients if they are already frail., Competing Interests: Conflict of interest None disclosed., (Copyright © 2021.

Background: Some older people stop visiting the dentist when they get older. This study aims to identify the characteristics and oral health status of older people who do visit community dental practices., Methods: In this exploratory cross-sectional study, the oral health of Dutch community-dwelling older people was assessed. A random sample of general dental practitioners and older people who visit the dental practice was drawn. The dentists were asked to prospectively select one older patient and describe this patient using a specially developed registration form; the patient was requested to complete a questionnaire. Data were described for 3 distinct groups of older people. Statistical measures for distribution and dispersion were used to describe the oral health of community-dwelling older patients in relation to the age., Results: A total of 373 (40.4%) dentist registration forms and 372 (40.3%) patient questionnaires were returned. Data were available for 364 (39.4%) dentist-patient couples. Amongst the patients, 52.8% were female and most had a high socioeconomic status. About 65.7% had one or more problems related to general health, and 75.2% used medication. Regarding the overall oral health status, the average number of teeth was 20, 3.5% were edentulous. Oral health problems were more common in the older patient group (aged 75+), in whom frailty was also most common., Conclusions: Older people who visit community dental practices are still relatively healthy, non-frail, and highly educated.  Even in this group, there is a turning point in both general and oral health from the age of 75., Competing Interests: Conflict of interest None disclosed., (Copyright © 2021 The Authors.

Current data on the prevalence of periodontitis is scarce. Moreover, in epidemiological research periodontitis is measured in different ways. However, for effective prevention and evaluation of curation, it is of great importance to have reliable prevalence figures on periodontitis, because serious periodontal infections show a strong correlation with several common diseases. In the case of the Netherlands, this means more effort to monitor the prevalence of periodontitis. This could, in any case, be carried out from dental practices, albeit that it would then be necessary to do so in a structured manner. This may not provide a full picture, but it will provide insight into the state of oral health and the outcomes of care for the vast majority of the population that visits a dental practice yearly.

Introduction: Dentists who have graduated recently from a Dutch dental school work mainly in the Netherlands, where collaboration and differentiation are relevant factors. Furthermore, the Netherlands face regional undersupplies of dentists. The objective of this study was to describe choices and aims of recently graduated dentists for the near future., Materials and Methods: An invitation for the web questionnaire was sent by e-mail to 945 dentists who had graduated from a Dutch dental school between 2013 and 2017, of whom 230 (24.3%) participated in the survey., Results: Approximately three quarters (77%) of the recently graduated dentists worked as a general dentist in a practice of some else, primarily in urban areas. The choice for a practice was affected by location, earnings, and the opportunity to gain experience. Furthermore, the career choices were affected most by the desired length of the working week and financial security. The narrow majority (53%) of the recently graduated dentists believed that in 5 years they will be practice owner; 49% expected to be a differentiated dentist. Furthermore, 41% believed they will work in a smaller municipality., Discussion: Although recently graduated dentists seem receptive to work in smaller municipalities, the peripheral regions are conceivably less appealing. Practice ownership conceivably is an option for the near future for a narrow majority of the recently graduated dentists., Conclusion: Recently graduated dentists have different preferences regarding their work situation in 5 years., (© 2021 The Authors.

Objectives: To assess the oral health of older people who visit the community dental practice from both the dentists' and the patients' perspective., Materials and Methods: In this exploratory cross-sectional study the oral health of Dutch community dwelling older people was assessed. A representative sample of general dental practitioners was asked to randomly and prospectively select one older patient and describe this patient using a specially-developed registration form; in addition the patient was requested to complete a questionnaire. The oral health of older people was described from the perspective of the dentists and the perspective of the older people themselves based on the definition of oral health from the World Dental Federation (FDI]. Relations between oral health of older people and dentist and older patient characteristics were analysed using Spearman's rank correlation coefficient (rho) and an ordinal regression model., Results: In total, 923 dentists were asked to participate in the study; data was available for 39.4% dentist-patient pairs. Dentists assessed the oral health of older patients as good or acceptable in 51.4% of the cases while this was the case in 76.2% of older patients themselves. The assessment of the dentist gets more negative with high treatment intensity and with older patients having certain diseases and more medication, while the assessment is more positive for older patients who visit the dentist on a regular basis. Older people's assessment of their oral health gets more negative by being female and with high treatment intensity, having certain diseases and higher use of medication., Conclusions and Clinical Relevance: Chronically illness as expressed by the number of diseases and the use of medication, seems to be a risk factor for poor oral health. Older patients themselves assess their oral health differently, mostly more positive, than their dentist., Competing Interests: No, the authors have declared that no competing interests exist.

Oral and general health are inextricable. In primary care, the fields of care by general practioners, youth healthcare, healthcare for older people and oral care are all distinctly separated. Healthcare professionals are increasingly confronted with the complexity and increase in Noncommunicable diseases (NCD's) and an aging population. The aetiology of NCD's in primary care concern the professional fields of all healthcare professionals mentioned, meaning that lifestyle-related risks might be prevented more effectively through collaboration. In primary care, the number of medically compromised people is on the rise and healthcare professionals encounter each other's patients, whose risks remain invisible to them. Through collaboration such problems could be faced more effectively. Better integration of oral care into primary care can also contribute to the quality of care and safety of care receivers, and reduce further inequality. In order to better design this integration with the help of innovation, more practicebased research and implementation is needed.

Among dental hygienists and dentists in the Netherlands, the impact of the SARS-CoV-2 pandemic on oral healthcare practices from March to July 2020 was investigated. Of the 1,700 healthcare providers approached, 433 completed questionnaires could be used. The results show that the pandemic has had a profound impact on both the accessibility of oral healthcare and on care provided in oral healthcare practices. Extra attention was paid to hygiene and infection prevention: the types of personal protective equipment and the protocols and procedures were adjusted by many oral healthcare providers. The confirmed prevalence of oral healthcare providers with COVID-19 in this study was 1.6%. However, testing was not available to all respondents with complaints during this initial period. Over half of the respondents estimated that even with additional measures there is an increased risk of infection to oral healthcare providers during their work. The efficacy of the various additional measures in oral healthcare practices related to COVID-19 is still unknown.

The practical training in dental schools in the Netherlands is largely organised within the walls of the educational institution, while many other medical educational programmes provide practical training to a large extent in the professional environment. The external practical internship is a form of practical learning with which positive experience has been gained in foreign dental schools, both by students and dentist-supervisors. The Dutch dental schools have a joint plan to set up practical internships in dental practices for master's students in the final year of their education. The aim of such an internship is that students in the last phase of their programme learn to apply the acquired knowledge and skills in an actual professional environment. This includes both clinical and dental treatment and the ability to organise oral health care for patients and everything that comes with it. This article describes the outline of this programme.

Background: Over the past several decades, changes in legislation and regulations have been implemented in oral health care in the Netherlands. In 1995, for example, a major transformation in the funding of oral health care was implemented, after which most oral health care for adults was no longer covered by national insurance. In 1997, the Individual Healthcare Professions Act, in which the authorizations of care providers were described, was established. The Healthcare Quality, Complaints and Disputes Act, established in 2016, concerns the accountability of professional behavior. Regulations concerning employment have changed several times since 1995. These changes have affected the work and practice situation of oral health care providers., Methods: Data from many publicly available sources were gathered and combined with internal reports mainly derived from the Data Stations project of the Royal Dutch Dental Association. This project was established in 1995 and, since its initiation, 6716 dentists have participated an average of 6.7 times., Results: Between 1995 and 2018, nearly all professional groups in oral health care increased, particularly those of dental hygienists and prevention assistants. The number of dental practices decreased, but practices got larger in terms of dental units, number of patients, and personnel. The percentage of inhabitants visiting oral health care professionals remained unchanged, but the type of care provided moved towards more prevention. Oral health care providers exploited new opportunities to enhance and express their professional behavior., Conclusions: Oral health care in the Netherlands has evolved in recent years toward more collaboration in teams, and professions have established institutions to promote the quality and safety of care. Greater emphasis has been placed on prevention of dental diseases. These processes were influenced by new legislation and regulations, demographic changes within professional groups, and other social developments.

The study of dentistry is known to cause high levels of psychological stress and physical strain. The aim of the present study was to determine the degree to which dental students experience study stress, burnout and physical complaints. The study showed female students experience higher levels of study stress, on average, than male students. Students' mean level of emotional exhaustion was 'high'. In addition, 90% of the students had suffered from physical complaints in the year preceding the survey. A strong correlation was shown to exist between physical complaints and emotional exhaustion, and in addition, a strong wish for more (pre)clinical teacher support correlated with study stress, burnout and physical complaints. It can be concluded that dental students, on average, experience the study as taxing, feel emotionally exhausted and suffer from many physical complaints. In the dental practice, they will be confronted with many taxing factors. In the dental curriculum, therefore, adequate and frequent attention should be given to learning to cope with stressful situations and to maintain physical well-being.

Work stress and burnout among Dutch dentists have been studied in the past; since then, however, considerable changes have taken place in practicing dentistry. The aim of this study was to investigate whether these changes are reflected in reported burnout and stress. Also, the study sought to investigate whether burnout could be associated with making mistakes during treatment or being confronted with a formal complaint. 500 Dutch dentists were randomly selected for an online survey, 105 of whom responded (21%); 50.5% male and 49.5% female. Higher mean scores on emotional exhaustion (EE) and personal accomplishment (PA) were reported, compared to previous results, and to reference scores from the burnout measuring manual, and lower mean scores on depersonalisation (DP) compared to reference scores. No gender differences were found for burnout. Women reported more work stress on Patient Contacts and Considerations about work. The 36 to 45-year-old age group reported higher mean scores on burnout and work stress. Having been confronted with patient complaints was associated with higher scores on DP, while worrying about making mistakes was associated with higher scores on EE and DP. Burnout is a relevant topic for dentists, which appears to be most prominent at middle age. Recognising, and knowing how to deal with, demanding aspects of work is a crucial means to prevent burnout.

The outflow of orthodontists through retirement is an important factor in the estimation of the required training capacity for this group of professionals. From 2002 through 2018, studies of the professional activity and retirement plans of orthodontists age 55 and older have been conducted fairly frequently, the most recent one dating from 2018. Based on the findings of these surveys, 3 estimations were obtained of the outflow through retirement. These were based on answers in earlier editions, the answers of their contemporaries and on the basis of the legal retirement age in the Netherlands. The number of active orthodontists in 2018 age 55 or older is estimated respectively to be 117, 116 and 102; according to all estimations, they will have retired in 2030. The estimations predict, respectively 56, 57 and 30 orthodontists will retire before 2023. According to 2 of the estimations, the outflow of orthodontists from the field will exceed the inflow from the universities in the coming years. The present training capacity in the Netherlands is not sufficient to compensate for the outflow of the first 2 estimations.

Dentists and dental specialists are qualified to prescribe drugs. In this study, we assessed and compared the pharmacotherapeutic knowledge and skills of final year dental students, dentists and dental specialists in the Netherlands. In 2017, a random sample of these three groups was invited to complete an assessment. The knowledge assessment comprised 40 multiple choice questions covering often prescribed drugs. The skills assessment comprised three patient cases for which participants had to write a treatment plan. For the knowledge assessment, the response rates were 26 (20%) dental students, 28 (8%) dentists and 19 (19%) dental specialists, and for the skills assessment the response rates were 14 (11%) dental students, eight (2%) dentists, and eight (8%) dental specialists. On average, all three groups had inadequate knowledge scores (smaller 80%) and only a small proportion (smaller 30%) of their treatment plans was assessed as correct. These results suggest that dental students, dentists and dental specialists lack prescribing competence, which could be caused by poor pharmacotherapy education during under- and postgraduate dental training.

Oral care for older people is an underexposed topic in dentistry as well as in general healthcare, while oral care professionals are increasingly confronted with frail and multimorbid older people with complex care needs. The research agenda 'Oral care for the elderly' was developed to encourage the collaboration of researchers in the Netherlands and Flanders (Belgium) to do more research in this area and in this way, to achieve an expansion and implementation of knowledge. This will make possible the provision of a socially responsible and robust basis for sustainable oral care for frail older people. The focus of the agenda is on 3 themes, namely oral health and oral function for older people; multi/interdisciplinary collaboration within primary care and the costs, benefits and long-term effect(s) of oral care throughout the entire course of life. This article provides an overview of this research agenda and the way in which it has been established.

Dental students and dental-care providers should be able to prescribe drugs safely and effectively. As it is unknown whether this is the case, we assessed and compared the prescribing competence of dental students and dental-care providers in the Netherlands. In 2017, all Dutch final-year dental students and a random sample of all qualified general dental practitioners and dental specialists (oral and maxillofacial surgeons and orthodontists) were invited to complete validated prescribing knowledge-assessment and skills-assessment instruments. The knowledge assessment comprised 40 multiple-choice questions covering important drug topics. The skills assessment comprised three common clinical case scenarios. For the knowledge assessment, the response rates were 26 (20%) dental students, 28 (8%) general dental practitioners, and 19 (19%) dental specialists, and for the skills assessment the response rates were 14 (11%) dental students, eight (2%) general dental practitioners, and eight (8%) dental specialists. Dental specialists had higher knowledge scores (78% correct answers) than either dental practitioners (69% correct answers) or dental students (69% correct answers). A substantial proportion of all three groups made inappropriate treatment choices (35%-49%) and prescribing errors (47%-70%). Although there were some differences, dental students and dental-care providers in the Netherlands lack prescribing competence, which is probably because of poor prescribing education during under- and postgraduate dental training. Educational interventions are urgently needed., (© 2019 The Authors. Eur J Oral Sci published by John Wiley & Sons Ltd.)

Oral health in frail older people is often poor. There are a number of reasons for this, such as increased morbity and decreased motivation for (self) care. Good oral health is, however, very important. Studies have revealed poor oral health to cause or aggravate several medical and psychological problems. Illness and medication can, in turn, damage oral health. Oral health among the elderly should therefore be carefully monitored and maintained. This requires multidisciplinary and interprofessional collaboration on the part of healthcare professionals and others involved. Such collaboration is now still very limited; hardly anything has been written about how such collaboration in the area of oral care for frail older people should or could be organised. This article provides an overview of the possibilities and the relevant factors in the area of oral care for the elderly in promoting collaboration among healthcare professionals and others involved. All of this is under the banner of 'united we stand'.

Late in 2015 the Royal Dutch Dental Association (KNMT) conducted a study of the therapeutic prescription of antibiotics and NSAIDs by dentists in general practice in the Netherlands and the factors influencing their decisions. Of the 1,087 dentists contacted 367 (34%) completed the online questionnaire. In the 4 weeks preceding the study they had prescribed an antibiotic to 1.3% of their patients on average. A fifth (20%) found it difficult to decide whether an anti-inflammatory drug is indicated and/or whether this should be an antibiotic or a NSAID. Questioned about medication decisions (whether or not antibiotics are indicated) in 11 fictional cases, 11% of respondents judged every case correctly. 39% undertreated, 24% overtreated and 26% both undertreated and overtreated. In the last two categories, dentists with non-Dutch degrees are overrepresented. More than half (55%) of the respondents say they need a guideline for prescribing antibiotics in dental treatment and 28% (also) need postgraduate education on this matter.

Caries progression seems to follow universal, predictable rates, depending largely on the caries severity in populations: the higher the caries severity, the higher the progression rates. Quantification of these rates would allow prediction of future caries increments. Our aim was to describe caries progression rates in the primary and permanent dentition in Western populations (not in lesions) of children and adolescents. Therefore, we systematically searched MEDLINE-PubMed, Embase, CINAHL, and the Cochrane library for studies reporting caries progression data. Eligibility criteria were reporting empirical data from at least 2 full-mouth dental caries examinations in a closed cohort during a follow-up of at least 3 y, a first examination after 1974, a second examination before the age of 22 y, caries assessed as dentine caries (d 3 /D 3 ), and caries reported in dmfs/DMFS (decayed, missing, and filled surfaces), dmft/DMFT (decayed, missing, and filled teeth), or caries-free participants. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we described the results for the primary and permanent dentition in a systematic review, performed a meta-analysis for the caries incidence rate in the permanent dentition, and conducted multivariate, hierarchical meta-regression analyses for the caries incidence rate and the increments in DMFS and DMFT. Of the 6,343 unique studies retrieved, 43 studies (56,376 participants) were included for systematic review and 32 for meta-analyses (39,429 participants). The annual decline in caries-free children in the permanent dentition ranged from 0.8% to 10.2%. The annual increment ranged from 0.07 to 1.77 in DMFS and from 0.06 to 0.73 in DMFT. The pooled caries incidence rate was 0.11 (0.09-0.13) per person-year at risk. Meta-regression analyses showed that the methods of individual studies influenced pooled caries incidence rates and increments in DMFS and DMFT. This should be taken into account in planning and evaluation of oral health care services. However, the caries incidence rate is promising for prediction of future caries increments in populations.

In 2013, the child abuse and domestic violence reporting code was introduced in the Netherlands, which obliged caregivers to report suspicions of child abuse or domestic violence. In 2014, a survey was conducted among dentists on this subject. However, nothing was known about the use of the reporting code among orthodontists. In December 2015, a survey was sent to members of the Dutch Orthodontic Society (NVvO). The survey consisted of 20 items about applying the reporting code and experiences with patients. Most orthodontists were aware of the reporting code (83%) and had implemented this in their practice (64%). Nevertheless, orthodontists found it difficult to recognise signs of child abuse, mostly because of a lack of experience in this area. Most orthodontists who suspected child abuse took action, mainly by seeking advice from the foundation 'Veilig Thuis' ('Safe at Home').

Background: In workforce planning for oral and maxillofacial surgeons in the Netherlands, it is important to plan timely, as these dental specialists are required to earn both medical and dental degrees. An important factor to take into account in workforce planning is the outflow of the profession through retirement. In the workforce planning in the Netherlands, it was assumed that retirement plans are a predictor for the actual moment of retirement. The purpose of this study was to investigate this assumption., Methods: A standardised survey to investigate the work activity and retirement plans of oral and maxillofacial surgeons was conducted seven times between 2003 and 2016. With some minor variations, in every edition, all oral and maxillofacial surgeons aged 55 years and older who did not indicate to be retired in an earlier edition were invited to participate. The data of all seven editions was analysed to investigate what factors influence the actual retirement age. For the analyses of the data, ANOVA and linear regression were employed., Results: The response rate was at least 80% in all editions. For all editions combined, 185 surgeons were invited one or more times, of whom 170 responded at least once. Between 2003 and 2016, the mean preferred retirement age increased from 63.7 to 66.7. Two thirds of the respondents who participated in more than one edition had revised their preferred retirement age upwards. Regarding the difference between preferred and actual retirement age, 45% of the oral and maxillofacial surgeons retired at a higher age than originally preferred and another 14% was still working at the age the originally preferred to retire. Linear regression shows that preferred retirement age is associated with sex and the number of working hours and that actual retirement age is associated with preferred retirement age, earlier preference to decrease working hours and working in non-academic hospitals., Conclusion: Altogether, it seems that in this group the preferred retirement age has some predictive value, but the oral and maxillofacial surgeons tend to retire at a higher age than they originally preferred to.

Objectives: To investigate which opinions among dentists are associated with level of technology use, when characteristics of the dentist and dental practice, as well as motivating work aspects are taken into account., Methods: A total of 1000 general dental practitioners in the Netherlands received a questionnaire on digital technologies they use, opinions on using technologies and related motivating work aspects. Questions were derived from expert interviews, the Dentists' Experienced Job Resources Scale and literature on technology implementation. Technology use was measured as the number of technologies used, and divided into three technology user groups: low (using 0-4 technologies, mostly administrative and radiographic technologies), intermediate (using 5-7, more varied technologies) and high technology users (using 8-12, including more innovative diagnostic technologies). Opinions on technology use and motivating work aspects were analysed using principal components analysis (PCA) and exploratory factor analysis. Scores on all components and factors were calculated for each respondent by computing the mean of all valid responses on the underlying items. Differences in these scale scores on opinions among the technology user groups were assessed using one-way analysis of variance and Kruskal-Wallis tests. A multiple linear regression analysis assessed the association of scale scores about opinions on technology use with the sum of technologies used, taking into account motivating work aspects and characteristics of the dentist and dental practice., Results: The response rate was 31%. Dentists who were high technology users perceived technologies as yielding more improvements in quality of care, adding more value to the dental practice and being easier to use, than low technology users. High technology users thought technologies added more value to their work and they reported higher skills and resources. They also focused more on technologies and thought these are more ready to use than low technology users. High technology users derived more motivation from "Immediate results" and "Craftsmanship" than low technology users. Personal and practice characteristics, motivating work aspects, and the opinion scales "Focus" and "Added value to dentist" explained 50% of the variance in the number of technologies a dentist uses., Conclusion: Opinions on digital technologies among dentists and motivating work aspects vary with level of technology use. Being more focused on technologies and perceiving a higher added value from using them are associated with using more digital dental technologies, when taking into account motivating work aspects and characteristics of the dentist and dental practice., (© 2017 John Wiley & Sons A/S.

FDI World Dental Federation, founded as Fédération Dentaire Internationale, has taken the initiative to develop the Oral Health Observatory, a mobile application to conduct oral health surveys worldwide. The aim is to collect reliable standardized international data on oral health and oral health care via a network of dentists. A proof of concept study project was set up in the Netherlands to test the methodology and to validate the approach. Data about caries, gingivitis, oral self-care and oral health related quality of life were analysed and compared to datasets validated in other studies. The Android app embeds three questionnaires addressing oral health history, status and patient behaviour. One questionnaire was completed by the patient and two by the dentist. The proof of concept study involved two phases: in the first phase, five dentists, regular participants in KNMT-surveys, evaluated the usability of the app; after the first phase, the app was adjusted for a second phase. For this phase an extra 15 dentists were recruited from a group of 20 other dentists: five of them declined to participate. Attention was paid to ensuring there was a proportional representation of gender, age and region. In the second phase the five first and 15 new participants collected data on up to a maximum of 38 patients. Data from this 653 patients correspond with results from previously published surveys on the prevalence of caries and gingivitis in the Netherlands. Hence demonstrating an association between caries and gingivitis with oral self-care, problems eating and experiencing oral pain. This proof of concept study shows that the app makes it possible to collect reliable information on oral health in a short period of time. Both dentists and patients evaluated the methodology as user-friendly. Altogether, the results of this proof of concept study are promising.

Objectives: The aim of this study was to investigate how dentists in the Netherlands and Flanders assessed their knowledge on oral health care to older people, what their attitude was and what barriers they experienced in rendering care to older people., Methods: The survey data was collected from a random sample of Dutch and Flemish dentists. Five hundred ninety-five dentists (37%) of the Dutch sample and 494 dentists of the Flemish sample (41%) completed the online questionnaire. Dentists were asked to respond to 15 Likert type items, representing opinions on provision of oral health care to older people and to give information about the number of older patients treated and about some profession-specific and personal characteristics., Results: The average number of patients treated per week was nearly twice as high in the Netherlands as in Flanders. Nevertheless, differences of opinions between dentists in the Netherlands and Flanders were relatively limited., Conclusions: This survey shows that in particular the actual number of older patients treated appears to be related with differences of opinions between Dutch and Flemish dentists about oral health care provided to (vulnerable) older people who live at home., Competing Interests: The authors declare no conflict of interest.

In this study, the prevalence of musculoskeletal symptoms among dentists and dental students in the Netherlands was inventoried by means of 2 corresponding web surveys. 196 (25% response) dentists and 359 (40% response) dental students participated. 80% of the dentists and 95% of the dental students reported to have suffered from pain in muscles and joints in the last 12 months. In particular, they mentioned complaints of the neck, the shoulders and the lower back. Dental students also frequently reported complaints of the upper back. Many physical complaints were more common among females than male students. In contrast, no gender difference was observed for dentists, but regarding this group stress proved to be an important risk factor for developing musculoskeletal complaints. Given the negative impact on the profession, further research into the prevention of musculoskeletal disorders is urgently needed, in particular about the efficiency of (postgraduate) education and occupational briefing in that domain.

Women currently make up 40% of the dentist population in the Netherlands. On the basis of enrolment in educational programmes their share can be expected to grow to more than half. The literature shows gender differences in preferences regarding work setting and duration of the working week. Men and women also differ from each other with respect to the way dental care is provided. The presented data demonstrate an increase in the number of women working in dentistry and research data have confirmed the presumed differences between male and female dentists. Women are less likely to be the owner of a practice, women who do own a practice are more likely to collaborate with colleagues and have a shorter working week. With regard to providing dental care, women seem to be slightly more orientated to the individual patient and are more likely to pay attention to the patient's general health. Theories about work values provide explanations for these gender differences. Women's preference for collaboration accords with the general development in dental care to work in teams.
