摘要:

AbstractBacteriologic and clinical studies suggest that sealants can be used therapeutically on incipient caries of the enamel. The present study was designed explore this approach further by determining whether there is a difference in retention rates on sound or carious tooth surfaces sealed for the first time as well as resealed surfaces. A total of 1766 teeth were sealed for subjects 12–14 yr of age of which 120 were judged to be carious. Mouths were divided sagittally on a random basis and an ultraviolet light activated resin with a filler or an autopolymerizing resin without a filler was placed on contralateral surfaces of all molar and premolar teeth. The effects of sealant type, caries status, arch and tooth type on retention over a 2‐yr period were tested using Mantel‐Haenszel statistics. At the end of 1 yr, 88% of the teeth sealed with the autopolymerizing resin were judged to be completely intact compared to 82% of the teeth filled with the ultraviolet light resin. At the end of the second year the retention rates were 84% and 75% respectively. The retention rates for carious and sound teeth at the end of both years were almost identical. Overall, premolars had a 15% more favorable retention rate than molars. There were minimal differences between arches although maxillary premolars had approximately a 5% higher retention rate than mandibular premolars. The reverse was true for molar teeth. Retention of sealants at the end of the second year (resealed after 1 yr) was 4% less than comparable teeth sealed init

摘要:

AbstractThe aim of this investigation was to determine if barium in drinking water, in combination with fluoride, has an effect on caries prevalence in a human population. Children, aged 12–14 yr, were selected from two towns which had a similar socioeconomic and racial balance but one had a barium concentration of 8.0–10.0 ppm in its drinking water and the other a level which was less than 0.03 ppm. The caries prevalence, as mean DMFS, was significantly lower in the high barium town (2.76 ± 0.82) than in the low barium town (5.14 ± 0.65). The difference in mottling scores between the two towns was not significant (P= 0.44, chi‐square test). This difference in mean DMFS between the high and low barium communities could not be explained by an effect of other covariate

摘要:

AbstractIn 1984 the Dental Attitudes Questionnaire, an instrument for assessing oral health care attitudes, was proposed. The DAQ has six content scales (Cynicism, Health Concern, Motivation, Oral Function, Social Aesthetic, Susceptibility) and two validity scales (Halo, Infrequency). The original items had an ‘agree‐disagree’ format. We compared this dichotomous format with a six‐point response format. Results obtained with the two‐point scale did not meet acceptable psychometric criteria. The six‐point scale resulted in acceptable item and subtest parameters and variance, internal reliability and test/retest reliability. For eight items, rewording was suggested. Future research i

摘要:

AbstractThis paper describes the evaluation of a Dental Health Mass‐Media Campaign directed at 5–7‐yr‐old children and their mothers. It aimed at increasing knowledge and awareness of dental health by making use of three different components: a: inserts in women's magazines; b: television commercial; c: material for home use distributed at schools. In order to study the relative recollection of the three components a representative quota sample of 164 mothers and 164 children were interviewed. The analysis of the results showed a high degree of recollection of the campaign in general. The material for use at home, distinguished from the other two components by demanding an active involvement of the participants, had the largest impact. The television commercial, merely demanding a passive involvement of the participants, was less well remembered, and the magazine insert had the lowest recollection. It is suggested that future national health education campaigns combine the mass‐media approach to increase health awareness with active involvement activities to stimulate behavioura

摘要:

AbstractThe relative importance of associations between caries occurrence and exposure to sugar‐sweetened products, fluoride preventives, medication with drugs affecting saliva secretion and the standard of oral hygiene was assessed in 125 mentally retarded and 79 healthy 9–10‐yr‐old Finnish children. The evaluation of the relative importance of the associations was based on logistic regression analyses. For the mentally retarded children the most important determinant of caries risk was their poor standard of oral hygiene. Frequent use of sugar‐sweetened snacks was found to be an important determinant of caries risk for both the mentally retarded and the healthy

摘要:

AbstractThe development and validation of a caries prediction model comprising 13 sociodemographic and dental examination variables on Grade 1 and Grade 5 children in the National Preventive Dentistry Demonstration Program are described. The objective was to derive a method of predicting children at high risk to caries early in order that preventive measures might be undertaken. True high risk children were defined in two ways: highest 25% of children based on their 4‐yr DMFS increment, and their total DMFS score at the end of the study. In both cases, children predicted to be at high risk were defined as the 25% with the highest discriminant score. Discriminant function and logistic regression analyses were used to determine the extent to which the 13 variables collectively discriminated between true high risk and non‐high risk children so defined. Sensitivity was approximately 0.50 and specificity around 0.82, using the 4‐yr increment as the criterion for defining true high risk, and approximately 0.64 and 0.88, respectively, using the final DMFS score for defining true high

摘要:

AbstractThis follow‐up of the oral health of children and young adults in Espoo, Finland, has been carried out using annual check‐ups done by dentists at the Espoo Health Center. There was about 80% participation in municipal dental care by 3‐ to 18‐yr‐olds. Each age group included 1700–2300 individuals. The DMFT‐index for 12‐yr‐olds was 6.9 initially and only 2.2 at the end of the 12‐yr follow‐up. The reduced DMFT and increased number of clinically caries free children is probably the cumulative effect of various preventive measures adopted during the follow‐up period. The proportional influence of ea

摘要:

AbstractA cross‐sectional epidemiologic survey was conducted of 618 Navajo Indians, aged 14–19, resident in a boarding school in New Mexico. Periodontal status was assessed by clinical measurements of attachment level and gingival bleeding, and evidence of alveolar bone loss from standardized bitewing radiographs. Attachment level and gingival bleeding were measured at 24 posterior interproximal sites (six sites in each quadrant): the mesio‐buccal aspect of the second molar; the disto‐buccal and mesio‐buccal aspects of the first molar and second premolar; and the disto‐buccal aspect of the first premolar. Alveolar bone level was measured from radiographs at the corresponding approximal surfaces of the same teeth. Attachment loss was considered present when the distance from the CEJ to the base of the pocket was>1 mm; bone loss was considered present when the radiographic distance from the CEJ to the alveolar crest was>2 mm, and gingival bleeding was considered present if bleeding occurred immediately after gentle probing. Attachment loss was evident at one or more sites in 88.7% of the population, 45.9% of the subjects had attachment loss at eight or more sites, and 101 subjects (16.3%) had one or more sites with at least 4.0 mm of attachment loss. Bone loss was present at one or more sites in 89.2% of the population, 28.6% had eight or more affected sites, and 4.7% (29 subjects) had one or more sites with at least 2.0 mm of bone loss. Gingival bleeding was evident at one or more sites in 70.6% of the population, and 19.7% had eight or more affected sites. None of the conditions were strongly associated with sex, but the prevalence of bone loss increased with age. The prevalence and severity of incipient periodontitis seemed much higher in these subjects than previously reported in other adolescent groups when similar diagnostic criteria and methods of measuremen

摘要:

AbstractIn order to determine the relative importance of periodontal disease, caries and non‐disease reasons for full mouth extractions, a combined socio dental study was carried out in an urban and a rural area in the Netherlands. In the largest proportion of patients (57%) caries was the predominant disease. In only a small group (13%) was periodontal breakdown the predominant characteristic. In 16% of the patients non‐disease factors possibly played a role because in this group no aeneralized periodontal disease or caries was found. It was concluded that in urban and rural areas and in all age groups caries and not periodontal disease was the most important reason for full mouth extractions. Non‐disease factors may play a role in the decision to carry out full mouth extractions. Patients living in areas with different dentist‐population ratios have a comparable caries status and periodontal condition at the time of full mouth extr

摘要:

AbstractAmong 20 333 people aged 15 yr or above, the prevalences of oral white lesions were calculated based on a partly new classification. The total prevalences were: cheek and lip biting 5.1%, smoker's palate 1.1%, frictional white lesion 5.5%, snuff dipper's lesion 8.0%, preleukoplakia 6.4% and leukoplakia 3.6%. If all these lesions were pooled, the prevalence was 24.8% and if only the entities cheek and lip biting and smoker's palate were excluded it became 20.1%. If weak “preleukoplakic” lesions were excluded from the latter figure (he prevalence for marked whitish lesions was 13.8%. Etiologic and clinical subgroups of leukoplakia showed the following prevalences: using the etiologic subgroups, idiopathic leukoplakia 0.7% and tobacco‐associated leukoplakia 2.9%; using the clinical subgroups, homogeneous leukoplakia 3.5% and non‐homogeneous leukoplakia 0.3%. The intraoral location pattern of leukoplakias was preponderant in the commissural and buccal areas. However, the idiopathic leukoplakias showed a somewhat more even distribution and thus a more similar distribution to that of oral
