AbstractDrawings about the dentist at work were solicited from 1,101 children in grades 2, 4, 6 and 8 in an urban school district. A system to classify the contents of these drawings was developed. The frequency of various items occurring in the children's drawings was determined. The “typical” or most frequent child's drawing of the dentist at work was described. This drawing contained a normal dental chair, dentist, a patient in the chair and dental cabinetry or furniture. The picture was a very matter‐of‐fact representation. Abnormal or bizarre pictures occurred infrequently. A few children drew pictures that did not relate to de

摘要:

AbstractA 3‐year experimental toothbrushing study was conducted in a natural fluoride area in Denmark to evaluate the anti‐caries effect of a 2 % sodium monofluorophosphate dentifrice. In a previous report the results for the total population of 1,407 schoolchildren, representing a broad age‐span (7–12 years), at the commencement of the study in 1970 were given. In the present report results are presented for two subpopulations of “8‐year‐olds” and “11‐year‐olds” at the commencement of the study. Differential analysis of the effect of the, test dentifrice on defined types of surfaces for the two subpopulations is given. The evaluation was performed using both the conventional DMF‐indices and the recently published ECSI‐Index6. The evaluation showed that the test dentifrice had a valuable anti‐caries effect in both age groups, above and beyond the effect of the waterborne fluoride. Proximal surfaces were affected most baneficially by the active agent both in relative and absolute terms. However, an appreciable caries‐preventive effect was also found on

摘要:

AbstractThe reliability of caries data obtained during three clinical trials is presented. Each of the three trials, conducted by different examiners, lasted 3 years and involved children aged 12 to 15 years. Reliability was quantified in terms of reliability coefficient and error variance, which allowed the effect of error upon the efficiency of each study to be measured. Reliability tended to be reduced when precavitation (initial) lesions were included in the DMFS count, but there was little difference between the reliability coefficients for each of four different surface‐types. Error was more important in 3‐year incremental rather than prevalence data, but nevertheless had a rather small influence upon sample size estimation or confidence limits of percent caries reducti

摘要:

AbstractThe oral health status of 454 children and 115 adults from a population of migrant and seasonal farm workers in Florida was assessed. The prevalence of disease among the children was consistent with that reported for other black children of this age. The migrants had received more dental treatment than the children of seasonal farm workers; however, the level of care for both groups was strikingly low. The results of this neglect were clearly reflected in the mouths of the adults, most of which were found to be in a very deteriorated state of dental health. A program to cope with these long unmet needs is unrealistic. Efforts should be made to eliminate pain and infection until the cycle of poverty can be broken.

摘要:

AbstractA distance exceeding 2 mm from the cementoenamel junction (CEJ) to the alveolar bone was observed on the proximal surfaces of the first molars of proportionally more 15‐year‐olds (101 subjects) than 13‐year‐olds (99 subjects). The measurements were performed on bitewing radiographs, and the methodologic error amounted to 3%. Recordings in excess of 2 mm were most frequent (0.27 and 0.23) for the distal surfaces of the maxillary

摘要:

AbstractThe periodontal condition of 300 Turkish troops was investigated using the modified Ramfjord Periodontal Disease Index. In addition, the gingival condition, presence and quantity of plaque and calculus, location and depth of periodontal pockets, tooth mobility, presence and severity of wear facets, diastema magnitude and the DMFT Index were determined. The average PDI was 3.8. Nearly 98 of the recruits suffered from gingivitis, 68% of whom exhibited moderate to severe inflammation without involvement of deeper structures. Moderate plaque accumulation and heavy calculus deposits were observed. An average DMFT of 5.09 was found. Little correlation was found between the relatively low DMFT rate and the Plaque Index.

摘要:

AbstractThe purpose of this investigation was to determine the mean ages at emergence of the permanent teeth of Icelandic children, as well as the mean ages at onset of the dental stages (DS). The material consisted of 1,941 randomly selected children, corresponding to 9.5 % of the total primary and secondary school population of Reykjavik. The mean ages at emergence of the permanent teeth, along with the ages at commencement of DS 2. DS 3, DS 4 and DS M2, are given. Owing to (he age distribution of the material, it was not possible to give mean ages at emergence of the first and third molars, or of the mandibular central incisors. A comparison of the emergence‐ages in Icelandic children with those of Danish and Norwegian children showed close agreemen

摘要:

AbstractThe prevalence of a number of malocclusion traits was investigated for 1,000 modern British caucasoid, 70 medieval British, 60 Anglo‐Saxon, 100 negroid and 100 mongoloid dentitions. Marked contrasts were evident in the sagittal, vertical and transverse occlusal and spacing anomalies between the various samples, with dental crowding being particularly prevalent in the modern British caucasoid sample and spacing between the teeth in the Anglo‐Saxon sample. The method of quantification of malocclusions was shown to be applicable for other epidemiologic stud
