AbstractThe purpose of this study was to evaluate the preeruptive effect of NaF tablets on caries in proximal surfaces of permanent molars and premolars. The material consisted of 47 subjects who had consumed fluoride tablets for a minimum of 5 yr between 1/2 and 6 yr of age in accordance with recommendations from the National Swedish Board of Health and Welfare (F+‐group) and 69 comparable children who had never consumed such tablets (F‐‐group). All had resided since birth in an area with a water fluoride concentration of 0.2 ppm and had been exposed to fluorides in toothpaste, mouthrinse solution and varnish since at least the age of 6. The children were examined by means of bitewing radiographs at the ages of 12, 13, 14 and 17. Two confounding factors, i.e. salivary counts of Streptococcus mutans and lactobacilli, were estimated and used for correction of crude caries differences. The mean values of these factors were higher in the F‐‐group than in the F+‐group. The results showed a statistically significantly higher caries prevalence in the F‐‐group compared to the F+‐group when the children were 14‐yr‐old, 4.4 vs. 2.9 DFS, corresponding to a caries reduction of about 34%. After correction for confounding, this was reduced to 24%, representing a non‐significant difference of 1.1 DFS but still indicating a preemptive effect. At the age of 17, the difference in caries prevalence was statistically not significant, 7.1 vs. 5.6 DFS, corresponding to a reduction of 21%. Based on corrected data, this was reduced to 15%. A main finding was that caries reducti

摘要:

AbstractTwelve‐yr‐old high caries‐risk children were identified by a low buffer capacity and high lactobacillus counts in stimulated saliva. A defined and standardized counselling technic was used, by which the children were recommended to reduce their sugar consumption. Seven weeks later the lactobacillus count in saliva was reduced to an acceptable level in 79%. The caries increment decreased by 66% over

摘要:

AbstractThe rapid growth in the use of panoramic radiographs provoked this survey of the reasons why general dental practitioners in Avon take such views. Of the 193 dentists who responded, 42 (22%) took one or more panoramic radiographs during a specified week. A total of 195 patients, 8% of those x‐rayed, had a panoramic radiograph taken either alone or in combination with other views. Panoramic radiographs were stated to have been taken primarily for the diagnosis of caries (48%) and surgical (24%), periodontal (20%), orthodontic (20%) and endodontic/apical assessment. These findings are discussed with respect to published guidelines on the use of panoramic radiographs and the teaching of radiology in dental school

摘要:

AbstractNinety‐seven teenagers were followed from the age of 14 1/2 to 19 yr. During that time they were given regular dental care by the Public Dental Service. Data concerning dental caries, gingival status, probing pocket depths, sub gingival calculus, defective fillings, loss of attachment and additional preventive care were recorded. The prevalence and increment of caries were low and at 19 one‐third of the subjects had still needed no proximal restorative care at all. However, in 26% of the 19‐yr‐olds sub gingival calculus was diagnosed radio graphically and during the study period gingival inflammation changed from being merely a result of poor oral hygiene to an indication of initial periodontal disease. There was a sex difference in dental health, which increased with age and was of clinical importance at 19. In spite of a good caries situation, most of the subjects were in need of individual care due to an initial periodontal problem. Furthermore, the change to a treatment strategy based on prevention requires regular check‐ups, and an extension of intervals between dental examinations could not be justified in this study, especially as it seemed to be difficult for the regular dentist to predict future disease on a clini

摘要:

AbstractThe purpose of the present cross‐sectional clinical study was to evaluate the relationship between recurrent caries prevalence, quality of class II amalgam restorations and various oral health parameters. One hundred and forty‐four randomly selected 35‐yr‐old citizens of Oslo were included in the investigation. Caries was scored based on a combined clinical and radio‐graphic examination according to the DMFS index system. Oral hygiene (OHI‐S) and periodontal index (PI) were registered, and the quality of class II amalgam restorations was ranked according to a set of occlusal index pictures. A total of 1694 class II amalgam restorations were included and 93 (5.5%) of these were affected by recurrent caries. A statistically significant correlation was found between prevalence of recurrent caries and poor oral hygiene, high Pi‐scores and prevalence of primary caries. However, a severe deterioration of the quality of amalgam restorations had to be present before a concomitant increase in recurrent caries prevalence could be registered. The present results indicate that measures improving the oral health may be of major importance in preventing recurrent caries and thereby increase the durability of amalgam

摘要:

AbstractBased on a literature review and recent surveys, the needs and implementation of preventive dentistry in China have been estimated. The average DMFT of 12‐ and 15‐yr‐old schoolchildren in Beijing were 1.61 and 2.11 respectively. The caries prevalence was higher in the coastal cities in the south. The caries rate was also higher in urban areas than in rural areas. There were some controversies in the results of fluoridation studies with one study reporting as high as 47.2% of the children to be afflicted with enamel fluorosis. The community periodontal disease status and treatment needs index (CPTNI) showed that 93% of the 12‐yr‐olds had bleeding, 98% had calculus and 15% had shallow pockets, with 100% of the children needing prophylaxis. There was a high prevalence of dental malocclusion with 54% of schoolchildren with dental anomalies, of whom 36% needed treatment. Much emphasis had been placed on oral pathology, oral medicine and maxillofacial surgery in the curriculum of Stomatology in Chinese denta

摘要:

AbstractThe prevalence of dental caries, the levels of oral hygiene and the periodontal treatment requirements were assessed in 3562 handicapped children and 1344 randomly selected normal children attending schools in Birmingham, UK. The effect of different types of handicapping condition on these parameters was also evaluated. This investigation showed that there were few differences in caries prevalence when comparing handicapped children with children attending normal schools. However, the provision of dental care showed significant differences, with the handicapped children receiving less restorative treatment. There were also significantly poorer levels of oral hygiene and a greater prevalence of periodontal disease in the handicapped children attending special schools. The type of handicapping condition had a significant effect on the periodontal problems observed; those children with mental retardation having the poorest levels of oral hygiene and the greatest periodontal treatment requirements.

摘要:

AbstractCaries, periodontal disease, oral hygiene and treatment needs were assessed in a group of handicapped adults. The study group comprised 199 individuals aged 17‐64 yr, most of whom were mentally subnormal. The mean DMFT values ranged from 17.4 in the 17‐24‐yr‐old age group to 26.9 in the 55‐64‐yr‐old age group. Tooth loss increased rapidly with advancing age. In all age groups the F component was less than 20% and high numbers of untreated carious lesions were found. Of the group studied, 90% needed some conservative treatment. Oral hygiene was poor and a high prevelance of periodontal disease was found. Of the dentulous persons, 49% needed scaling and 34% complex periodontal treatment. The percentage of study group patients requiring dental treatment was very high, so that it can be concluded that dental care for the handicapped is insufficient. This situation must be improved and a suitable system for the delivery of preventive measures must be devised for this group of t

摘要:

AbstractIn a previous study the concept “patient involvement” was found to be strongly predictive of therapy outcome. On the basis of a questionnaire concerning patients' background and motivation, 82 patients were interviewed before treatment. To cover the concept “patient involvement” 16 variables were considered as relevant measures. In a factor analysis four factors accounted for 90% of the common variance. The factors were interpreted in terms of: 1) initial attitudes, 2) attendance, 3) self‐confidence and 4) teeth

摘要:

AbstractIn an attempt to determine the association between overall health status, medication history, and oral hygiene status and root caries, 24 older persons residing independently in the community and 23 residents of a nursing home were interviewed and received oral examinations, using the Oral Hygiene Index and the Root Caries Index. The mean age of this population was 80 yr, with the nursing home subjects somewhat older than community‐dwelling subjects. Only six persons had no root surface caries; three subjects had caries on all tooth surfaces with gingival recession. Mandibular teeth, particularly molars and premolars, showed the greatest attack rate. The best predictors of root caries were number of teeth remaining, calculus, plaque, and the use of medications with xerostomic effects. Medications were most predictive of maxillary root caries. The results point to the need to provide interceptive dental therapeutics for high risk geriatric populations such as those using multiple medications and with a poor history of oral car
