AbstractThe associations of denial caries with poor oral hygiene and high sugar consumption were analyzed taking into account possible confounding and factor interaction. The series consisted of 543 children from low‐fluoride areas (0.10–0.46 parts/106), aged 5, 9 and 13 years Plaque accumulation and sugar consumption were slightly confounded throughout the observations. Effect‐modification appeared to exist, since the effect of one factor was greater at higher levels of the other. The association between the amount of plaque and dental caries was statistically significant at all levels of sugar consumption. With increasing total sugar consumption the risk of caries increased significantly only when oral hygiene was simultaneously poor. Effect estimates (E) and attributable risk estimates (AR) were calculated for increased plaque accumulation and sugar consumption. For the total sets of tooth surfaces in the various age groups the proportions of the total caries load associated with increased plaque accumulation were 35.2–63.0%, and those associated with higher total sugar consumption 0.7–5.4%. The fractions varied greatly with the tooth group. The effect estimates for the two factors in combination were always greater than the sums of the separate effects, indicating synergistic interaction between the two caries det

摘要:

AbstractThe objectives were to demonstrate that a combination of preventive regimens could significantly reduce dental disease in a school population, to demonstrate the feasibility of a school‐based program in relation to sustained benefits. There were 1286 students in 1st and 6th grades enrolled in the study. Subjects were stratified by grade, sex, and race and randomly placed in a treatment or education group. Procedures included ingestion of fluoridated water, oral hygiene education program, dental examinations, prophylaxis, acidulated phosphate fluoride gel (1.23%) applied in trays, pit and fissure sealants (bis‐GMA) on occlusal surfaces of all eligible posterior teeth, and provision of all restorative care. Fluoride and sealant procedures were repeated at 6‐month intervals. After 3 years the treatment group was randomly divided to provide a group that would not continue with treatment and serve as a comparison. The study population was enrolled in 18 schools and clinical procedures were provided on‐site, using mobile denial vans. Five‐year results indicate high degree of success with fall‐off of benefits to those for whom treatment was terminated. This pilot program gives strong evidence for the possibility of implementing school‐based dental programs. The study also indicates that prevention programs must be comprehensive and continuous for maximum ben

摘要:

AbstractA randomized, double blind clinical trial of the caries inhibition effects of dentifrices containing respectively monofluorophosphate and amine fluoride was performed. A third control group used a toothpaste without fluoride. A total number of 2008 schoolchildren ranging in age from 6 lo 8 years and living in Strasbourg (France) participated in this study. After a baseline examination three groups were constructed with the block randomization technic. The caries inhibition effects of the three dental pastes were compared after 3 years of unsupervised use. The monofluorophosphate dentifrice showed a reduction of 7.02% for DMFT, 5. J 7% for DMFS and 25 26% for the df rate. The reduction of amine fluoride dentifrice caries was respectively 21.62% for DMFT, 20.94% for DMFS and 48.66% for the df rate.

摘要:

AbstractA longitudinal study of the frequency of dental visits has been conducted on a sample of 1302 individuals aged 20–60 years. These individuals had previously been interviewed regarding their dental care habits. They had also (subsequent to the interview) been clinically examined by a dentist. The results presented are based on the official dental care consumption statistics if, Sweden, and thus differ from the information obtained from the interviews. In all age groups women had a higher frequency of dental visits than men. The average number of courses of treatment carried out over a 4‐year period was 2.0. Only 23% of the individuals received treatment once a year or more often, whereas 79% received treatment at least once during a period of 4 years. These figures were lower than those reported in the interviews. Individuals with a higher number of courses of treatment had also had a higher frequency of dental visits before, had been called in by their dentist for check‐ups, had a higher income and knew more about teeth and their care, used oral hygiene aids daily and were living in metropolitan areas. Younger people with many remaining teeth and those with many decayed teeth had had a higher frequency of courses of trea

摘要:

AbstractThe utilisation of preschool dental services was examined prospectively in a birth cohort of New Zealand 4‐year‐old children. There were highly significant associations between non‐utilisation of dental care services and a series of measures of family social background and the quality of care provided to the child. Factors associated with increased risks of non‐utilisation of dental services included: mother of non‐European ethnic origin; low gross family income; single parent family; non‐attendance at preschool education facilities; failure to attend community nurse services and a lower utilisation of routine child health care services including immunisations and routine postnatal checks. The implications of the non‐utilisation of preschool dental care are discussed in the context of the more general problem of providing an adequate and equitable standard of health care

摘要:

AbstractThe Danish oral health care delivery system is a publicly funded, predominantly school based system of care for children and adolescents and a private practice copayment national health insurance mode for adults. Study of this dualistic system can provide useful information to dental public health practitioners. Interviews with experts in the Danish oral health care system and a selected review of the literature demonstrate that improvement trends are occurring in the oral health status of both adults and children. These improvement trends can be directly related to a combination of treatment and preventive measures undertaken by the country as a whole, and to specific interventions for certain subpopulation groups, such as preschoolers. Four key variables can be defined which have contributed to the success of the Danish oral health care delivery system (DOHCDS). These include 1) the role of private sector input into the development of the DOHCDS, 2) demography, 3) the Danish value system, and 4) the structure of the DOHCDS.

摘要:

AbstractIn 1980, the population of Danish schoolchildren in grade 9 formed the first cohort which, throughout all school grades, had been covered by the Child Dental Health Services including free orthodontic care. National statistics on prevalence of malocclusion for this cohort of about 60000 children in grades 3, 6, and 9 (approximate ages: 9, 12, and 15 years) were compared with corresponding frequencies in a population of schoolchildren in the 1960s among whom orthodontic treatment was rare. From the comparison it is inferred that treatment priority, based on professionally defined need, had been given to occlusal anomalies of the incisor segment transverse anomalies of the lateral segments, and crowding.

摘要:

AbstractA method was developed in which a dental chart schematic, printed on a standard 80‐column computer card, could be used to record DMF data for analysis using mark sensing technology. The binary image of each column was read by a standard card reader and this information was used to create a detailed DMF analysis. This method uses readily available technology and could be modified for many research purpose

摘要:

AbstractThe effects of the optimistic bias of R2on oral health data were investigated by means of a cross validation study in which the number of predictors in a regression model was manipulated. The use of too many predictors increased positive bias and reduced the true predictive quality of a regression model and should be avoided through the use of appropriate stepwise procedures.

摘要:

AbstractThe periodontal status of 680 industrial employees in Adelaide, South Australia, was assessed in a descriptive epidemiologic survey. Full mouth recording using the recently proposed WHO ‘TRS 621’ survey method (14) was used by two calibrated examiners. Periodontal disease in this population was highly prevalent and typically of moderate severity. Only 4.2% of the subjects were free from any signs of periodontal disease. In 11.1% the disease manifestation was confined to reversible gingivitis. Mild periodontal disease was evident in approximately 60% and severe disease in 25% of the population. The major treatment requirement in all age groups could be categorized as “simple periodontal treatment” manageable by non specialist dental resources. More than 90% of pockets detected occurred interproximally. Some features of the proposed WHO ‘TRS 621’ survey methodology ar
