Clinically undetected occlusal dentine caries: a radiographic comparison.

The occlusal bite-wing radiograph evaluations of 131 14-year-old and of 123 17- and 20-year-old Dutch persons were compared with the clinically collected observations. The clinical observations and the bite-wing radiographs were collected as part of a longitudinal epidemiological survey conducted in 1987 and 1990. Comparison of the evaluations of the first and second molar teeth showed significantly more radiolucencies in all three age groups than expected clinically. Of the clinically judged 'sound' surfaces, 26% in the 14-, 37.5% in the 17- and 50% in the 20-year-old group showed a radiolucency on the bite-wing radiograph. In the 14-, 17- and 20-year-old age group a radiolucency was noticed on the bite-wing radiograph in 32, 44 and 58% of the sealed teeth, respectively. The radiolucencies below the occlusal enamel of sealed teeth were most likely due to the problems in diagnosing occlusal dentine lesions correctly with the clinical diagnostic methods. Therefore not only approximal but also occlusal bite-wing radiograph judgement before sealant application seems to be advisable now. Because of the numbers of clinically undetected lesions it may be advisable to reconsider the criteria for occlusal diagnosis in epidemiological surveys and to judge not only the approximal but also the occlusal surfaces in epidemiological surveys when bite-wing radiographs are available.

[Dentists about dental anxiety and the treatment of anxious patients; a pilot study].

Dentists' attitudes towards dental anxiety and management of anxious patients were objects of a pilot study. Dentists from The Netherlands participated in a group discussion. Results show that dentists understand dental anxiety in their patients. However, upon closer consideration the picture they give of themselves in this respect appears to be too positive. The role of the dental assistant is generally considered to be very important.

[Informed consent in dentistry in The Netherlands].

In The Netherlands a new law, concerning the doctrine of informed consent, will be incorporated in the Dutch civil code. Some consequences for dental practitioners are discussed. The conclusion is that it is necessary that the dental profession has to re-examine its standards of conduct towards patients.

[Dentist and scientific dental information in mass media].

Mass media, such as newspapers and magazines and to a lesser degree TV and radio can provide the public with a lot of scientific information about dental diseases. Especially when it concerns research results with news value or controversial issues. Dentists regarded by the public as the most reliable sources of scientific information about dentistry, can get into problems by the publication of such issues in mass media. Particularly when patients ask questions about developments in certain fields of dentistry (for example periodontology or implantology) covered by the mass media. In this article the importance and the value of communication of scientific information are discussed. The relevance for dentistry is illustrated by means of a series of articles on scientific dental subjects published, during fifteen years, in a Dutch national newspaper. Finally the responsibility of dental faculties and professional organisations when they provide research results to the press and other mass media is pointed out.

Social desirability and questioning children in dental research.

The influence of social desirability on the results of a social dental investigation was examined in a survey of 320 15-yr-old children. Children with a lower level of schooling seemed to be more inclined to give social desirable answers. It appeared that the stronger the social desirability, the more satisfaction children tended to show with their dentist, the less they said they were afraid of him, but, surprisingly, the less responsible they felt for their dental health. Other measures were not influenced by social desirability: dental hygiene, perception of the quality of one's own teeth, knowledge about dental health, sources of information, and evaluation of the dentist's behavior. Also independent of social desirability were the measures of the amount of fluid sugar consumed, the child's obesity, and the actual dental health (DMFS, degree of treatment, P.H.P.). Several aspects of the meaning of social desirability in dental research are discussed.

[Burden and power. 2. Problems of dentists].

Are dentists exposed to mental strains? And are dental students mentally prepared to meet the demands of their future, daily practice? Practice problems as reported by dentists are classified and discussed in relation to age and satisfaction. Dentists are distinguished into two types and the consequences of strains for both groups are mentioned. The role of the professional organizations in regard to diminution of the problems is described, as are several defence mechanisms.

[Burden and power. 3. Problems of dental patients].

For many people a dental visit is a burden, for some a too heavy one. Reasons for either or not making dental visits are considered. Many regular dental attenders are not very interested in their teeth and in many persons avoiding a dentist a disinterest in the teeth is absent. The behavior during dental treatment seems largely to be influenced by pain, feelings of defenselessness, absence of social support and of coping abilities.

[Edentulous patients visiting a dental ombudsman. Their questions and problems].

Data are presented of 321 edentulous patients (women 67%), mean age 65 years, who visited a dental ombudsman in the period September 1980-May 1987. Many of these patients had several complaints: 41.5% three and more. Many of the problems (134 patients) are behavioural and psychological by nature. The majority of the patients (65%) ask for advice during the consultation. One may get the impression that this group of patients has had these problems already for a longer period and that they feel that a general practitioner can't help them effectively. For this special group of patients a dental ombudsman may serve as a useful mediator.

Supply of dental health information by 182 Dutch organizations working in the field of dentistry.

Little is known about the exchange of Dental Health Information (DHI), as part of the dental health education process, between the Dutch public, organizations active in or related to dentistry and Dutch dental professionals. Based on the ideas of HAVELOCK a communication model was developed. The main question was: how and through which organizations is information supplied, on what subjects related to dental health? A group was formed, consisting of 182 organizations and institutions and 85% decided to collaborate with the study. Telephone interviews were used for the sampling of the data. Of the 154 organizations and institutions only 56% reported to be active in the field of DHI. Preventive information appears to be the main subject. Not the public, but dental professionals and other provider groups are seen as the main target groups. DHI activities appear to consist mainly of providing written information material with a preventive content. These activities are hardly evaluated. Further on: there seems to be no central coordination for DHI activities in the Netherlands. It is concluded that in the field of DHI activities the resource system (organizations and institutions who generate information) and the users system (the public and dental patients) are not in accordance with each other.

Dental patients asking for a second opinion: what oral problems do they have?

The oral and dental problems of a group of 235 patients, who asked for a second opinion consultation, were surveyed. More than 80% of the group were regular dental attenders (once or more times a year); 70 patients were advised by their own dentist to visit the "second opinion" dentist. The oral problems were classified in eight categories. Most of the problems concern the condition of the oral cavity (20%), the urgency of certain treatments (18%), and the quality of care delivered by the own dentist (17%).

Psychological aspects of patients with burning mouth syndrome.

This article reports the results of a psychological questionnaire survey of 184 patients who have burning mouth syndrome. The results are compared with normative data obtained in the Netherlands. In general, it may be concluded that in a large number of patients with glossodynia, psychological aspects such as anxiety, depression, and neurotic tendencies are of great importance. However, it must be emphasized that this conclusion may not be interpreted as support for a psychogenic cause of the syndrome or for a strong psychological factor in the etiology of glossodynia.

Psychologic correlates of dental anxiety.

In an attempt to establish the relationships between dental anxiety and personality traits, such as neuroticism and locus of control, a survey has been carried out among 30-40-yr-olds in a Dutch town. In the first instance, the questionnaires comprising the psychologic items were treated by Non-Metric Principal Components analysis to detect the underlying structure. The principal components found were then used in a second-stage analysis. The results appear to be at variance with the literature, i.e. subgroups discernible in the sample by sets of psychologic features were not associated with dental anxiety categories.
