摘要:

AbstractThe present study was undertaken to investigate the prevalence of dental caries in a group of 20‐year‐olds who had previously participated in Public Child Dental Health Services. Dental caries was related to social status and preventive visits to the private dentist after termination of school. The study population comprised 389 persons aged 20, out of which 313(80.5%) were examined clinically and radiographically by one dentist according to standardized criteria. Mean DMFT was 10.4 and mean DMFS 16.7. Differences in relation to sex were not significant. The distribution of subjects according to DMFS was uneven. The 20% with the highest DMFS accounted for about 40% of the total amount of DMFS and for about 45% of the total amount of DS. A consistent pattern with higher mean DMFS in the low social groups was found. Attendance to Regular Youth Dental Service was higher the longer the subjects had been students and higher mean DMFS was found in nonregular attenders. The presence of a high caries risk group is discussed in relation to the dental care system received by the study populat

摘要:

AbstractThis study analyzes the consumption of dental services in Israel and is based on data collected on households and their expenditures on dental health. Medical and social research in Israel generally take into account the significance of the ethnic dimension to explain findings. In accordance with this established research mode, interview subjects were divided into two groups: households with both parents born in Asian or African countries, and others. Analysis of the data established a difference between the two groups in their expenditures on dental services. While several studies focused primarily on the sociologic aspects of the problem, little attempt has been made to isolate the influence of economic factors on dental care. This study demonstrates that income and other socioeconomic variables characterizing the various ethnic groups are the underlying causes for the difference in dental care expenditure.

摘要:

AbstractThe relationship between malocclusion and the health of the masticatory apparatus is reviewed. While there is evidence that certain features such as traumatic deep overbite, unprotected incisors and impacted teeth may adversely affect the longevity of the dentition, the relationship of dental irregularity to periodontal disease, caries and mandibular dysfunction is less certain. Studies in the Held of social psychology indicate that an unattractive physical appearance may evoke an unfavourable social response in many facets of social interaction but the place of dentofacial anomalies in this context has not been satisfactorily assessed. The individual's adjustment to his own imperfections in dental alignment is variable and there is no evidence that children with visible irregularities will in general be emotionally handicapped. Effectiveness studies have yet to be undertaken but the factors which will have to be taken into account in assessing the benefits of orthodontic treatment are the definition of treatment need, treatment standards, the disadvantages of treatment and the influence of other determinants of dental health. The need for further research is underlined.

摘要:

AbstractThe effect of reducing the abrasivity of toothpaste on dental caries was observed in a 3‐year clinical trial involving 1106 11–13‐year‐old Berkshire schoolchildren. The children were divided into three groups; Group 1 were allocated a low abrasivity paste containing 0.8% sodium monofluorophosphate, Group 2 a paste of conventional abrasivity also containing 0.8% sodium monofluorophosphate and Group 3 a low abrasivity non‐fluoride paste. After 3 years the net DMFS increments (clinical and radiographic scores combined) were 4.22 in Group 1, 4.72 in Group 2 and 6.43 in Group 3. The differences between Groups 1 and 3 and between Groups 2 and 3 were highly significant (P<0.001). The mean increment in Group 1 was lower than in Group 2 but did not reach statistical significance. Reducing the abrasivity of the toothpaste had no meaningful effect on the standard of oral hygiene and prevalence of gingivitis as measured by the Gingival and Plaqu

摘要:

AbstractThe DMF Index and its components have been utilized by various researchers to measure aspects of the caries process ranging from prevalence of carious lesions to the amount of dental care needed. It is generally recognized that DMF Teeth (T) measures life‐time caries experience and is not a good predictor of the amount of treatment time needed in population groups. The purpose of this study is to evaluate the ability of certain modifications of the DMFT components to predict the amount of treatment time needed. In a sample of 109 adult cases, normal and diseased conditions were coded along with the usual DMFT measures and the number of missing teeth needing replacement (NR). Corresponding treatment procedures related to caries (periodontal treatment was not coded) were recorded and then converted to treatment times using the Relative Productivity Unit (RPU). Stepwise multiple regression and discriminant analysis procedures were used. The number of D teeth was linearly related to treatment time, but the number of NR and M teeth was not. Regression procedures indicated that the square root values of D and NR were the best predictors of treatment time (RPU) and produced a multiple r of 0.69. When patients were classified into categories of treatment time (low, medium, high), the DMF Treatment Time Index was able to correctly classify 70 % of the cases into their appropriate treatment time categor

摘要:

AbstractPeriapical radiographs were taken of central incisor and first molar teeth in 264 Nigerian boys (12–20 years) from a school in Lagos. From the radiographs, bone loss involving central incisors and first molars was measured. Bone loss was evident in 28.4% of subjects examined. The prevalence of bone loss rose through the age groups from 23.2% at 12–13 years to 34.6% at 18–20 years. Over all ages the prevalence of bone loss involving mandibular central incisors was 14.4%, mandibular first molars 9.8%, maxillary first molars 8.3% and maxillary central incisors 7.6%. Two subjects showed features characteristic of juvenile periodontitis (periodont

摘要:

AbstractThe purpose of this investigation was to gather information on caries prevalence in schoolchildren of Arab and Jewish populations, and compare caries prevalence according to sex, age and population examined. Altogether, 3672 children were included in the survey (1975)Jews, 1001 of whom were females; and 1697 Arabs, 840 of whom were females). During the examination only dental caries were checked. Caries were marked according to the DMF index. Compared to former years there is an increase in the prevalence of caries throughout the population. A slightly lower caries prevalence was found among jewish children than among Arab children of the same age. However, when DMF is broken down into its component parts, Arab children were seen to have a greater number of teeth affected by caries and in need of treatment (D). Furthermore, treatment need has been met to a much greater degree among Jewish children than among Arab children. Arab children received almost no dental care.

摘要:

AbstractThe purpose of the present study was to establish whether the number of intact teeth in Helsinki schoolchildren aged 7–13 years was rationally correlated with the wartime reduction in sugar consumption and, later, with dental health education programs in Finland. The period covered is 44 years. The results show that dental health education is effective in caries prevention and that enforced programs can lead to an improvement similar to that seen during the wa
