摘要:

AbstractEpidemiologic studies in which oral health in schoolchildren in the non‐fluoridated city of The Hague has been monitored, have revealed a substantial decrease in caries prevalence since 1969 in groups of all socioeconomic status (SES). Because of a still significantly higher caries activity in children of lower socioeconomic classes in 1981 a weekly fluoride mouthrinsing program in these children was started. The purpose of the present study was to investigate the cariostatic effectiveness of a weekly 0.2% neutral NaF rinse in children with low caries prevalence. A sample of 29 schools stratified according to SES and randomly assigned to two groups was selected. One group of schools (14) performed weekly rinsing and the other group (15) served as controls. After 3 yr the number of children available for re‐examination had dropped from 501 to 333, of which 62.2% had written parental consent for radiographic examination. Statistical analysis of the data showed that fluoride rinsing could establish a reduction in caries incidence only in children who did not use fluoride tablets. The results of this study are of special interest for health authorities in planning and implementing public dental health measu

摘要:

AbstractMagnesium oxide and bone meal were used as chemical defluoridating agents to reduce excessive amounts of fluoride from artificial water samples which had been prepared to simulate Kenyan water samples with a fluoride concentration ranging from 1 to 9.3 ppm. The water filtrate from bone meal was clear and palatable. The filtrate from magnesium oxide was slightly slimy and cloudy, but palatable. Either of these chemical agents may be used in simple defluoridation procedures in rural and suburban areas using borehole water to reduce the excess fluoride in the water to beneficial non‐toxic levels. Both magnesium oxide and bone meal are inexpensive chemicals and readily available in Keny

摘要:

AbstractIn this paper the principles and particular problems involved in applying economic appraisal to the evaluation of preventive dental care are investigated. There is no cost benefit analysis in the existing literature which gives a reliable indication of the relative efficiency of preventive and restorative dental techniques. This is because of difficulties involved in trying to attach monetary values to the benefits of programmes which are publicly provided. These difficulties are not resolved by representing the benefits of prevention by restorative costs averted. Although cost effectiveness analysis may seem a more straightforward method, it suffers from the inappropriateness of the dmft (or dmfs) statistic for measuring the relative effectiveness of restorative and preventive treatments. An alternative measure of dental health outcome is suggested which encompasses aspects of the quantity (in life years) and quality of teeth produced by restorative and preventive care. The full potential of economic appraisal of preventive dentistry will be realised only if such comprehensive measures of dental health outcome are produced. The task of producing such measures should involve dentists, consumers of dental care and health care re searchers.

摘要:

AbstractPrevious research on a group of school‐based mouthrinsing programs showed costs per participant to increase with program size. This paper examines the behavior of average costs as they relate to wages and labor productivity. Costs arc found to increase because of differences in the mix of voluntary and paid labor. As program size increased, administrators substituted relatively high priced paid labor for low priced voluntary labo

摘要:

AbstractStudies using plaster models of teeth and photographs simulating the full range of occlusal conditions have found high agreement between measures of adolescent social acceptability of these conditions and perceived need for orthodontic treatment. This study examined the association between adolescents' acceptability of their own occlusal condition, severity of malocclusion, and likelihood of undergoing orthodontic treatment. The factors predicting the acceptability of occlusal condition of 13‐yr‐olds, as assessed by the SASOC scale, were measurements of acceptability of general physical appearance, and the severity of occlusal condition. Variability in SASOC scores appeared to be independent of gender, socioeconomic status, and ethnicity. Gender, and severity of occlusal condition were important differences between subjects who had received, planned, or were undergoing orthodontic treatment, and those who had not. Neither SASOC scores nor perceived need for treatment accounted for a significant proportion of the variance between these groups. Although adolescents seeking orthodontic treatment had a greater severity of malocclusion than those not, little difference was observed between these groups in acceptance of occlusal condit

摘要:

AbstractThe relationship between the presence of malocclusion and maintenance of teeth in adulthood was studied in a randomly drawn sample of 499 35–44‐yr‐old Danes. Maintenance of teeth in the past was expressed through the number of teeth present, attachment level and information of regularity of dental visits. Maintenance at present was expressed as caries present, plaque and gingivitis. The relationship of these parameters to the presence of a malocclusion symptom was analyzed directly and the indirect influence was studied through the influence of a subjectively perceived malocclusion and its impact on satisfaction. It appeared that satisfaction was significantly related to maintenance of teeth and to a positive dental behavior. A perceived malocclusion was shown to have a negative influence on satisfaction and thus indirectly on maintenance. If a public orthodontic service is aiming at lifetime maintenance of teeth, malocclusions leading to dissatisfaction with teeth and a subjectively perceived need should be taken into consideration when ranking children with regard to treatment pri

摘要:

AbstractReasons for full mouth extraction in an urban and a rural area in The Netherlands (dentist‐patient ratio 1:2500 and 1:5700 respectively) have been studied. Patients who participated in this combined sociodental research project were those who received full mouth extractions over a period of 1 yr. The combined patient response was 75% and the overall dentist response 90%. In the urban and the rural areas respectively 137 and 237 cases of full mouth extraction were recorded. When comparing the dentists' diagnoses with the conditions of the dentitions there appeared to be a fair degree of agreement in most of the cases, although some striking deviations were also found. In the relationship between the patient's opinion and the condition of the dentition some unexplained discrepancies were found: 37% of the dentitions in which the teeth and attachment were in a healthy condition were perceived as bad by the patients. Dentists and patients agreed in their perceptions of the dental conditions in 60% of the cases. In 27% there was a strong disagreement. In most of the discrepancies found plausible explanations could be given. In some cases this was not possible. As this involves a substantial minority of cases, dentists should be aware of reasons other than the clinical condition in the disabling treatment of full clearanc

摘要:

AbstractThe purpose of the present study was to examine the relation between oral hygiene habits, denture plaque, presence of yeasts and stomatitis in institutionalised elderly. A sample of 201 residents, 48–99 yr of age (mean age 82 yr), was selected from four different institutions in Lothian, Scotland. Clinical recordings were carried out under standardised circumstances using well recognised indices. Information about oral hygiene habits was obtained through structured interviews conducted immediately before the clinical examination. A multivariate analysis, principal component, was carried out on the correlated five maxillary denture plaque scores and two components, accounting for 74% and 12% of the variation, were identified. Using these two independent variables, an analysis of variance was carried out testing for significance between the four effects: soaking habits, brushing habits, denture stomatitis and growth of yeats in the palate together with their interactions. The analysis showed significiant relation between maxillary denture plaqre, soaking habits and the presence of denture stomatitis. The was no relation between denture plaque and brushing habits or between denture plaque and growth of yeast

摘要:

AbstractFibre optic transillumination (FOTI) has been employed during the course of a 3‐yr clinical dentifrice trial which initially involved 3003 children. At the initial examination, a subgroup of 813 13‐yr‐olds, and at the following annual visit, 2247 14‐yr‐olds, were examined using a 150 W lamp and 0.5 mm diameter probe. Routine clinical and radiographic examinations were performed separately. Compared to the clinical scores for anterior teeth, FOTI detected an additional 64% of interproximal lesions at the first visit while, for the larger number of children at the second visit, the increase in lesion detection level using FOTI was 37%. For the posterior teeth the comparable figure at the second examination was 92%. When FOTI data were compared to radiographic data for more than 52 000 posterior interproximal surfaces, FOTI could only detect 17% of radiographic Grade 2 lesions and 48% Grade 3 lesions. Thus any assumption that FOTI diagnoses may be a substitute for bitewing radiography appears

摘要:

AbstractFluorosis of the primary dentition was determined in 146 children living in a hot, dry African village with a fluoride concentration in the drinking water of 0.98–2.7 ppm. The prevalence of fluorosis was compared using Dean's(8) and Thylstrup&Fejerskov's(14) indices. The prevalence varied according to tooth type, being highest in maxillary second molars (25%) and lowest in mandibular central incisors (4.6%). The two scoring systems produced almost identical prevalences of fluorosis but the severity scores varied. Generally Thylstrup&Fejerskov'sindex scores were one score higher than Dean's. The Thylstrup&Fejerskovindex is recommended for future studie
