Prevalence in the Dutch adult population and a meta-analysis of signs and symptoms of temporomandibular disorder.

A nationwide survey of oral conditions, treatment needs, and attitudes toward dental health care in Dutch adults was carried out in 1986. One of the aims of the study was to assess the prevalence of signs and symptoms of temporomandibular disorder (TMD). A sample of 6577 persons (from 15 to 74 yr of age), stratified for gender, age, region, and socio-economic status, was contacted. Of this sample, 4496 persons participated in the behavioral part of the study, of whom 3526 were examined clinically. The TMD prevalence was based on (1) perceived signs and symptoms of TMD and (2) clinical examination of joint sounds, deviation, and pain on mandibular movements. A total of 21.5% of the Dutch adult population perceived some dysfunction, and 44.4% showed clinically assessed signs and symptoms of TMD. In nearly all age groups, the signs and symptoms of TMD appeared more in women than in men. Agreement between the results of the clinical examination and the anamnestic dysfunction index was significant (p < 0.0001); however, the Pearson's correlation coefficient was low (r = 0.29). The odds-value (risk-ratio) that subjects who perceived signs and symptoms of TMD would present with clinically assessed signs and symptoms of TMD was 2.3. The results of the survey were compared with results of a meta-analysis performed on 51 TMD prevalence studies. The analysis revealed (1) a perceived dysfunction rate of 30% and (2) a clinically assessed dysfunction of 44%, both based on compound samples of, respectively, over 15,000 (23 studies) and over 16,000 (22 studies) randomly selected subjects.

Trends in dental caries in The Netherlands.

Until 1985, epidemiological studies in The Netherlands were focused on school-age children. Up to that year, few caries prevalence data for (young) adults in selected groups were available. In 1986, the first National Dental Survey of the adult population was carried out in The Netherlands. Lack of information made it impossible for trends in dental caries in adults to be studied on a scientific basis. However, with use of cross-sectional studies conducted on selected adult populations between 1970 and 1989, an indication of a trend in dental caries is described. Evident changes in the age-specific average DMFT scores took place in the younger age groups. In the older age groups, the average DMFT score has not changed. Changes in percentages of edentates in the period 1980-1990 probably reflect part of the changes in oral health status of Dutch adults.

[Dental caries in children from ethnic groups in the Netherlands. A literature review].

This article reviews the literature on child dental caries in various ethnic groups in the Netherlands. Material from fifteen studies showed generally the dental health of five- to eleven-year-old children of parents born in Turkey or Morocco to be far worse than that of children of Dutch or Surinamese parents. The ethnic groups distinguished, however, turned out not to be homogeneous with regard to dental health. Within each ethnic group the socio-economic status as well as the parental level of fluency in the Dutch language were important additional risk indicators for caries. Regular toothbrushing seemed to be the most important factor to diminish the caries risk.

[Ethnicity and the 'TJZ' decision].

The aim of this study was to assess differences in oral health and dental behaviour in a cohort of five-year-old children born in 1982 and a cohort of eleven-year-old children born in 1976, in different ethnic and socio-economic groups, in the period from 1987 to 1990. To this end a secondary analysis was performed on data collected in a study monitoring the oral health of sick fund insured youths in The Netherlands. Large differences in dental health and dental health behaviour were found between ethnic and socio-economic strata. Thus, in the 1982 cohort, the caries prevalence and incidence were highest in the stratum of children of Turkish or Moroccan mothers with a low or unknown education. In the 1976 cohort, the caries prevalence and incidence were highest in children of Dutch parents with a low or unknown education. It is concluded that both stratification variables were caries risk indicators.

[Caries in children from ethnic groups. An investigation in five-year-old children in Amsterdam and their parents concerning risk indicators and factors].

A previous study has shown five-year-old children of parents originating from Turkey or Morocco to have twice as much dmfs as children of parents from The Netherlands, Surinam or various other countries. In the present study, other risk indicators and factors for the prevalence of caries amongst these children were studied by interviewing their parents at home in their mother tongue about their preventive dental behaviour. Results showed educational level of the parents, and gender of the child to be important risk indicators, apart from ethnicity. Risk factors were the age of the child, at which the parents had started to brush the teeth of the child, the use of fluoride tablets and the regularity of the brushing behaviour.

[Long-term effects of preventive dental care in toddlers].

A study was executed to investigate the relation between the motivation of the mother to engage in preventive dental behavior, the level of her school education, her place of birth and furthermore the use of fluoride tablets by the child in the age period 1 1/2 - 6 years on the one hand and the caries experience at the age of 6 and 15 years and the prevalence of fluorosis at the age of 15 years on the other. The year of birth of the child was taken into account as a possible confounding factor. A significant relation was found between the use of fluoride tablets and the prevalence of fluorosis. The most important predicting factor for the caries experience of the child was the mother's motivation to engage in preventive dental behavior. An effect of fluoride tablets on the caries experience could not be demonstrated.

Oral health and dental behaviour in 11-year-old children of different ethnic groups.

This investigation was first, to assess the oral health of 11-year-old children in four ethnic groups in Amsterdam; second, to assess their dental behaviour and third, to identify potential determinants of frequency of toothbrushing. Representative samples of 97 Surinamese, 209 Moroccan, 128 Turkish and 102 Dutch children were examined orally and asked to complete a questionnaire. Results showed that Turkish and Moroccan children had higher mean DMFT and DMFS scores than the Surinamese and the Dutch children. The mean plaque scores in the Turkish and Moroccan children were higher than those in the other two groups. Large differences in frequency of toothbrushing were found between the four ethnic groups, the Surinamese and Dutch children claimed to be the more regular brushers. Logistic regression analysis showed that the frequency of toothbrushing was related to the children's attitude towards toothbrushing and not to parental influence.

Use of fluoride tablets and effect on prevalence of dental caries and dental fluorosis.

A study was executed to investigate the relation between the use of fluoride tablets by children in the age period 1.5-6 yr on the one hand and the caries experience at the age of 6 and 15 yr and the prevalence of fluorosis at the age of 15 yr on the other hand. The year of birth of the child, the motivation of the mother to engage in preventive dental behavior, the level of her school education and her place of birth were taken into account as possible confounding factors. A significant relation was found between the use of fluoride tablets and the prevalence of fluorosis. The most important predicting factor for the caries experience of the child was the mother's motivation to engage in preventive dental behavior. An effect of fluoride tablets on the caries experience could not be demonstrated.

Risk indicators and potential risk factors for caries in 5-year-olds of different ethnic groups in Amsterdam.

The aim of this study was threefold: first, to assess the oral health of Turkish, Moroccan, Surinamese, Dutch and "other" 5-yr-old children living in Amsterdam; second, to identify risk indicators for caries, in addition to ethnicity; and third, to identify potential risk factors related to differences in caries experience in these children. Results showed the mean dmfs scores of Turkish and Moroccan children to be much higher than that of the Dutch and Surinamese children; 8.1 and 8.2 versus 3.6 and 3.4, respectively. The educational level of the parents and the gender of the children were important risk indicators, in addition to ethnicity. The age of the child at which the parents had started to brush their child's teeth, the use of fluoride tablets and the regularity of the brushing behavior in the past could be identified as potential risk factors.

[Epidemiology of dental caries in the Netherlands].

Both in 6- and 12-year-old Dutch children the prevalence of dental caries has declined remarkably between 1970 and 1985. However, in 6-year-olds the decline terminated after that period, while it continued in the 12-year-olds. In 1986 a national dental survey of the caries prevalence of older age categories was executed. As no comparable caries data are available from an earlier period of time, no certain conclusion can be drawn about changes in adult caries prevalence. A comparison of the national data mentioned to data from a country where the caries prevalence in children did not decline (former DDR), suggests that Dutch adults younger than 25 year have a relatively low caries experience at this moment.

[Cessation of fluoridation of drinking water; results of caries research in Tiel and Culemborg in the period of 1968-1988].

In December 1973 water fluoridation was discontinued in Tiel, the Netherlands. Six years later an epidemiological study was started, with the aim to investigate the consequences. In the period from 1979 to 1988 a yearly caries investigation was carried out in 15 year old children born and living in Tiel and children living in the control town of Culemborg, where the drinking water had never been fluoridated. The 15 year old children in 1979-1980 in Tiel had a 18% higher caries experience than the same age group in 1968-1969, to whom fluoridated water had been available from birth onward. In the same period a 28% decrease of the caries was found in Culemborg. In 1979-1980 the DMFS-index in Tiel was still 36% lower than in Culemborg. Between 1979-1980 and 1987-1988 the caries experience decreased in both towns.

[Dental survey. Part XV. Dental visits 2: motivation and practice].

This paper is part of a series on the national oral health survey in the Netherlands (LEOT-project). In a previous article the results on dental attendance (as far as behavior and knowledge are concerned) were described. This paper presents the results concerning the other determinants of the dental attendance behavior of the dentate Dutch population. The dentate Dutch is reasonably content with the dentists behavior. About 10% however, requires more information. Anxiety remains for about 55% a negative aspect of dental visits; in 10% of the cases this leads to postponement of the visits.

[The activity package of the dental assistant].

The aim of this study was to assess the package of activities that is actually carried out by the chairside assistant, and the activities that should be dropped or added to the package, according to both assistants and dentists. A representative sample of 1034 dentists and their assistants received a questionnaire. Results showed large differences between assistants in kind and number of activities actually carried out. Part of the group of assistants as well as part of the group of dentists expressed their wish to extend the package of activities.

[Oral health and ethnicity. An epidemiologic investigation in 5- and 11-year-olds in Amsterdam].

This study investigates whether the oral health of 5- and 11-year-old children of immigrants from Turkey and Morocco is worse than that of Dutch peer groups in Amsterdam. The outcome variables considered were dmft/s. DMFT/S and the index-components, amount of plaque and number of tooth surfaces sealed (only 11-year olds). The explanatory variable considered was ethnicity (Turkish, Moroccan, Dutch, Surinam and 'Others'). The mean dmfs-score of Turkish and Moroccan 5-year olds was significantly higher than that of Dutch children: 8.1 and 8.2 vs. 3.6, respectively. Also a significant difference in mean DMFS-score between Turkish and Dutch 11-year olds was found; 3.3 vs. 1.7, but not between Moroccan and Dutch children. On average 1.8 surfaces were found sealed in 11-year olds. The mean plaque scores observed in Turkish and Moroccan five- and 11-year olds was significantly higher than in Dutch children. It was concluded that the oral health of Turkish and Moroccan children in Amsterdam was worse than that of their Dutch peer groups and that programs should be developed aimed at improving this situation.

Plaque, calculus, gingival bleeding and type of tooth cleaning device in a Tanzanian child population in 1984, 1986 and 1988.

In 1984, 1986 and 1988 a mixed-longitudinal study was carried out to determine the prevalence of plaque, calculus, gingival bleeding and type of tooth cleaning device amongst school children in Morogoro, Tanzania. The background parameters considered were age, geographical location and sex. The reproducibility of the methods of diagnosis was assessed. In general, more children possessed a chewing stick than a toothbrush, except urban children. The prevalence of visible plaque decreased and the prevalence of calculus increased with increasing age. Gingival bleeding was not age-dependent. Urban children had significantly more surfaces covered with visible plaque, but had a significantly lower prevalence of calculus, than rural children. Boys showed a significantly higher prevalence of visible plaque and calculus than girls. In the majority of those with gingival bleeding, only 1 of the 6 examined papillae was involved, most often the mesio-lingual papilla of the 3.6. The children had not been subjected to organized oral health care and professional intervention. The findings of the study indicate the need for organized school-based oral hygiene programmes in the area in order to improve the periodontal health of these children.
