[Nationwide survey in the Netherlands (Leot-Project). 7. Dental prostheses].

Data are presented about the prevalence of full and partial dentures and dental bridges in the adult population of The Netherlands. Furthermore, the quality of full dentures and the resorption of the jaws were studied. Differences were found between the social classes (a higher percentage of people with dentures in the lower classes) and between the various regions of the country (more denture wearers in the Northern region). Only a low percentage of the full dentures met all the quality requirements. This can be possibly explained by the fact that resorption of the lower jaw was severe in a majority of the cases.

[Cosmetic dentistry].

A nationwide dental survey was carried out in The Netherlands. One of the objectives of the study was to assess the objective and subjective need for cosmetic dentistry in the Dutch adult population. A stratified sample of 2784 dentate persons, aged 15 to 74 years, participated in the study. The esthetics of anterior teeth and bicuspids in upper and lower arches were assessed by the dental examiners as well as by the examinees. Analyses of the data showed that 15.8 to 62.6 percent of the people in the age-range form 15 to 74 years was in need for cosmetic dental care, according to the dental examiners. Based on the patient's opinion (subjective need) these percentages varied between 17.5 and 40.4 percent. The discrepancy between the objective and subjective assessment in the percentage of people in need for cosmetic dental care increased with age. The results indicate that there is a need for cosmetic (restorative) dentistry in The Netherlands.

[Dental characteristics and orthodontic treatment need of the Dutch adult population].

In this article the results are presented of a nationwide representative study of dental anomalies in the group of 15-74 years Dutchmen. Also the subjective and objective need of orthodontic treatment in the age group 15-34 years is described. The principal findings are: of the 15-19 years olds, 27% is treated with orthodontic appliance; general practitioners performed 45% of these orthodontic treatments; --unsatisfied with the position of the front teeth is 25% of the 15-34 year old; an objective need for treatment is found in 39% of this age group; in 14% there is both an objective and a subjective need for treatment; both the subjective and objective need of orthodontic treatment is greater in the group of persons who were treated in the past than in the group of persons who never were treated.

Long term results of chemotherapy on the developing dentition: caries risk and developmental aspects.

The dental health of 45 children who had been placed on long term evaluation after chemotherapy treatment for malignancies was examined in this study. All children had received cytotoxic drugs during the period of tooth formation. It was found that they had more filled or diseased permanent teeth than control children. Their current caries activity as indicated by initial white spot lesions was also higher. Forty-three of the children showed evidence of disturbed amelogenesis. This had resulted in aesthetically displeasing grooves, pits and discoloration. Twenty-three of the children were counseled on the possibility of cosmetic dentistry. Delayed eruption and shortened, malformed roots were also found on several patients. It was concluded that these patients constitute a high risk dental care group.

Value of bite-wing radiographs in a clinical epidemiological study and their effect on the DMFS index.

The aim of this study was to determine, for different age groups, the additional value of bite-wing radiographs compared to the clinical information, and to calculate the subsequent effect on the DMFS index. Subjects were 14, 17, 20, 23 years old, or in the age groups 25-34 and 35-54, who participated in a clinical epidemiological survey. After obtaining consent, bite-wings were taken of approximately 25% of the participants (n = 663). The extra diagnostic yield of the bite-wings varied between 163 and 700% for approximal dentine caries diagnosis of untreated surfaces, and between 233 and 593% for inadequate restoration judgement for filled surfaces. The DS score went up by about 20-98%, whereas the DMFS index increased between 1 and 12%, resulting in a radiographic correction factor of 1.01-1.12. In conclusion, the considerable increase in the prevalence of approximal dentinal lesions and inadequate restorations for all age groups results in higher numbers of surfaces in need of treatment, but is not accompanied by a significant increase in DMFS scores.

Effect of the routine professional application of topical fluoride on caries and treatment experience in adolescents of low socio-economic status in the Netherlands.

The purpose of this study was to study the effect of professionally applied topical fluoride on oral health status at the population level in adolescents with low socio-economic status. Adolescents attending dental clinics where professional fluoride application was a routine procedure (high-fluoride group) were compared to adolescents from other clinics (low-fluoride group). The study consisted of a questionnaire, a clinical examination and two bitewing radiographs. X-rays showed no statistically significant differences in the number of DS, FS or DFS. Clinically, there were no statistically significant differences in the number of FS or in the number of DFS. The low-fluoride group had a statistically significant higher number of DS than the high-fluoride group. The results indicate that professionally applied fluoride has no effect on caries and treatment experience in a population. These results justify a randomized clinical trial on a population level to study the effectiveness of professionally applied topical fluorides.
