Support is an important factor in the implementation of clinical practice guidelines. Data from 5 studies from 1998 through 2013 offer insight into the support for clinical practice guidelines among dentists, orthodontists, dental hygienists and denturists in the Netherlands. In these, attitudes, opinions, knowledge and behaviour were seen as indicators of support. Dentists have an increasingly positive attitude towards clinical practice guidelines. The majority is aware of and uses at least 1 of the guidelines available to them and are in favour of the development of clinical practice guidelines. Orthodontists and dental hygienists have available few such guidelines, but the majority of both groups favour their development. Among denturists, who also have little experience with clinical practice guidelines, there are fewer supporters for their development. All in all, among caregivers in oral healthcare in the Netherlands, support for the use and development of clinical practice guidelines is growing.

In 2013, to evaluate the functioning of the complaint procedure of the Royal Dutch Dental Association (KNMT), an anonymous, written survey was conducted among 955 dentists and dental specialists, for whom in the period mid-2008 to mid-2013 a complaint was handled. 413 (43%) participated in the study. 51% of them reported that the complaint was successfully mediated by the Regional Mediation Boards and the Specialist Mediation Board and 17% that the patient had withdrawn the complaint. For the remaining 32% the complaint was handled by the Central Complaint Committee, who determined that 13% was (partially) substantiated, 17% was not substantiated and 2% was settled. Generally, 79% of the dentists are (mostly) positive about the procedure of mediation, while 8% are neutral and 13% are dissatisfied about it. With regard to the complaints procedure this was 60%, 11% and 29% respectively. The judgment of the dentists about the Regional Mediation Boards and the Specialist Mediation Board and about the Central Complaints Committee is influenced by the success of the complaints procedure and by the impact of the complaint that was experienced. The emotional support of dentists during the complaints trajectory is one of the points requiring attention.

It is known that a patient's complaint can have a serious impact on the well-being of dentists. But little is known on the nature and the extent of this impact. That's why in 2013 an anonymous survey was conducted among 955 dentists and dental specialists, for whom in the period mid-2008 to mid-2013 a complaint was handled through the Complaint Committee of the Royal Dutch Dental Association (KNMT). Altogether, 413 (43%) of them participated in the study. 71% of the respondents reported that the complaint had influenced their professional practice. 52% reported that it had (also) influenced their attitude towards colleagues and patients, and 60% (also) experienced an impact on their mental and/or physical condition. Altogether, 68% reported that they had unpleasant feelings and 75% stated that the treatment relationship with the patient was terminated as a result of the complaint.

Since 1995 the Dutch Dental Association (NMT) has carried out research on, in particular, the non-clinical aspects of dental practice with the Data Stations project. At present, within this research project 5 studies are conducted on a regular basis: the Dental Consumption Study, the Dental Practice Study, the Omnibus Survey, the Young Dentist Study and the Quality of Oral Care Study. From the results of this research project it appears that during the last decades dentists have increasingly been working cooperatively. This is expressed in dental practices with more dentists and more staff workers, with more dental chairs and more patients. The length of the working week, however, has changed very little over the years. Among both young people and adults gradual changes have taken place in dental consumption during the period 1997-2011. By intensifying the collaboration with clinical dental researchers the scope of the research within this project can be expanded to include the quality of oral care and the effects of care which has been provided on oral health in The Netherlands.

The Dutch Dental Association (NMT) surveyed dentists who graduated in 2004, 2005 or 2006 concerning their work situation and plans for the future. They were also asked about their experiences at the start of their career In general, the recently graduated dentists did not face difficulties at the start of their professional life. Most dentists worked in the practice of a colleague, but the majority ultimately wanted to have their own practice. The latter applied more to men than women. Furthermore, there was a clear preference for working within a team and most of them planned to specialize in a specific branch of dentistry. The survey also revealed that the delegation of tasks to dental hygienists and prevention assistants was more or less taken for granted by recently graduated dentists.

As part of a broader study of the restorative care index of 5- and 6-year-olds and 11- and 12-year-olds, a sample study was carried out among 1,361 dentists, who were surveyed by means of a web-questionnaire concerning this issue. In total 447 dentists (33%) filled in the questionnaire completely. Concerning the development of dental care of children, opinions differed widely: 46% of those questioned spoke of an increase in the incidence of caries during the past 5 years and 44% reported no change. Furthermore, dentists hold different views on the treatment of the primary dentition. There was no consensus of opinion about the necessity of treating caries in young children and there was a comparable lack of agreement about how and when treatment should be given. The majority of dentists express a need for support in their practice (possibilities for referral, protocols, informational material) concerning routine oral examination, the preventive and/or curative treatment of (young) children.

In 2007 a study was undertaken of the restorative care index of the teeth of children under the age of 18. The aim of this study was to gain insight into the factors associated with the restorative care index in children. Factors investigated were (post-) brushing, inspection frequency, sweets-consumption frequency, socio-economic status and treatment or lack thereof by a general practitioner or dentist who works in a clinic for child health care. This study made use of statistics assembled for an earlier study of children formerly covered by public health insurance in the municipality of The Hague and research carried out at child dental clinics. Socio-economic status and the level of oral care were correlated with dental quality. No patient-bound factors were significantly correlated with the level of care. There was however a positive correlation between the'type' of dentist (family dentist or dentist associated with a clinic for child dental care) and the chance of curative treatment (in the case of developing caries).

Patient education is an important part of the care provided in a dental practice. Explanations concerning dental treatments is in the majority of practices exclusively the responsibility of the dentist. Information about oral hygiene and prevention is generally provided by oral hygienists and prevention assistants. It is striking that agreements are made concerning the form and content of patient education, the division of responsibilities and the use of teaching aids in only 39% of practices. It is possible that this has to do with the relatively few hours that oral hygienists and/or prevention assistants are active each week in the practice, and the judgement of the dentists that sufficient time has to be devoted to discussing a proposed treatment with the patient.

In support of its quality policy, the Dutch Dental Association (NMT) has undertaken a survey to examine dentists'views on continuing education, accreditation, and their postgraduate course attendance. In December 2004 a written questionnaire was sent to a sample of 710 dentists, of whom 504 (71%) responded. The data were analysed using SPSS. Most dentists (93%) attended one or more courses since January 2003. They tend to concentrate on a few subjects, mainly on clinical procedures. About half (45%) of the respondents are in favour of continuing education accreditation for dentists. Compared to opponents, supporters are more positive about continuing education in general and spend more time reading specialist literature. Furthermore, the greater part of dentists indicates that it is important to have some kind of quality mark for postgraduate courses.

The project 'From care-demand for care to a social dental occupational and educational structure' was carried out to reach an agreement about the organization of the future social occupational and educational structure and the future performance of one's profession. A descriptive analysis of data, obtained by literature search and consensus-meetings was used. All relevant professional associations participated in this project. The project resulted in profiles for the future dental professionals and for the future dental team. In this project the dental professionals come to an agreement about the future professional performance. However, the discussion has not yet been finished. Further collaboration between the professional associations is recommended.

Objective: Obtaining information about differences between male and female dentists in practising dentistry and about changes in practice arrangements., Design: Descriptive analysis, using SPSS (CROSSTABS, ANOVA, HOMALS), based on information on the way(s) dentists practice their profession., Setting: Department of Research of the Dutch Dental Association (NMT), Nieuwegien, The Netherlands., Methods: A survey by means of a questionnaire, among a representative sample of 229 female dentists and a representative sample of 483 male dentists., Results: Female dentists have on average fewer patients than male dentists, spend fewer working-hours weekly at their chair and practice more often in some form of partnership. Females have a spouse working in the dental practice less often than males and, while the spouse of males most often works as a dental assistant, the spouse of female dentists is most often also a dentist himself. Compared with male dentists, in 1994 female dentists more often had to arrange cover by a locum while in 1995 they had to take more days of leave due to personal illness or exceptional circumstances., Conclusion: In the Netherlands there are substantial differences in the practice of the profession by male and female dentists. This is important for the future policy of the NMT with regard to the required manpower in dentistry.

In many Western countries during the past decades there has been a strong increase in the number of women dentists. This review on current literature shows that women dentists differ from their male colleagues in their way of practising the profession. More so than men they prefer to work in a group practice or in some kind of partnership. Women dentists also appear to have relatively smaller practices than their male colleagues and on average they practise fewer hours per week. However, it is important to notice that for women dentists motherhood is an important restricting factor with regard to practising their profession, often resulting in career break and diminishing professional productivity. Because of the strong increase in the percentage of women dentists, it is important for future policies to recognise their specific issues and concerns, as well as the consequences for dentistry of their way of practising. Thus, planning of manpower and infrastructure of dentistry can be done in a more adequate way.
