AbstractThe effect of fluoridated milk consumption has been investigated in a follow‐up study of 269 children aged 3–9 years. Children consumed 200 ml of milk daily, fluoridated in the groups 3–5 years with 0.4 mg F−, and in those aged 6–9 years with 0.75 mg F−, for 300 clays yearly. The caries data were analyzed with special regard to changes in the DMF values of the permanent first molars, the yearly examination data of the corresponding age groups compared and correlated with the length of fluoridated milk consumption. Statistical analysis of the permanent first molar data showed significant negative correlation between DMF means and length of fluoridated milk consumption in children 5–6 years old at the time of evaluation. The caries reduction after 3 years was 74% and statistically significant (P<0.001). In children 7–9 years old the caries reduction of the permanent first molars was less, and statistically not significant. A slight reduction of DMFS mean values in the front teeth of this group co

摘要:

AbstractWe examined 1316 pupils, average age 16.6 years, in a small town in Serbia. The purpose of this study was to find out the effects of the oral hygiene on the condition of the periodontal tissues and the frequency of gingivitis and periodontal disease and their severity in this age group. The presence and quantity of dental plaque were registered according to the Silness&Löe Plaque Index. The amount of dental calculus was determined according to the Greene&Vermillion method. The condition of periodontal tissues was evaluated by Ramfjord's method. It was found that only 5.3% of the examined pupils had a clinically healthy periodontium. Gingivitis was discovered in 60.6%, and periodontal disease (with periodontal pockets) in 34.1% of the examined pupils. The average PDI was 1.8. We revealed great quantities of soil and hard deposits on the teeth of examined pupils. The average Plaque Index was very high (1.9)

摘要:

AbstractThe pattern of dental service utilization, the perception of periodontal disease, and the oral hygiene habits among 642 industrial employees were evaluated using a self‐administered questionnaire against background variables of age, sex, and socioeconomic strata. Of the study population, 50.5% had their most recent dental visit within the previous 12 months and 42.5% claimed to seek regular check ups. There was no significant association between time intervals since the last dental visit and age, sex, occupation, income or education. Regular visits were made more often by subjects in the higher occupation and income level. Multivariate analyses of the number of missing teeth simultaneously considering age, sex, socioeconomic level, regularity and frequency of dental visits revealed that except for age and sex, no other factors were significant. The most common reason for not seeing a dentist in the previous 12 months was an assumption that “nothing was wrong”. A large majority of the group surveyed were unaware of the presence of periodontal disease or the need for its treatment, despite the high prevalence in all subgroups. Periodontal status was not significantly associated with sex, socioeconomic levels, regularity of frequency of dental visits, but there was a significant regression on age. The study population's pattern of service utilization was found to be similar to that reported for the general population, and it was anticipated that the hygiene habits of the group was representative of the total community. If that assumption is true the high prevalence of periodontal disease of the study population probably exists in the general comm

摘要:

AbstractPresence of clinically diagnosed TMJ dysfunction and the length of sick leaves were significantly associated in a sample of 599 male Finnish shipyard workers. Neglect of dental health care did not seem to be an explanatory factor, because the amount of untreated caries and the regularity of dental care did not differ significantly between the orthofunction and dysfunction groups. Although the association is no proof for a causal relationship, TMJ dysfunction may explain at least a part of the increase in days on sick leave, because dysfunction was found to be common and at best symptomatically treated in the population studied.

摘要:

AbstractIn the course of a recent experiment a group of 314 mothers with very young children were visited at home by a dental health educator on three occasions. Mothers were given advice about dental health for their children and were offered a free supply of fluoride drops. Results drawn from questionnaires Completed at each home visit suggested that dental health education given in this way was able to influence maternal altitudes and behaviour. Virtually all mothers accepted the offer of fluoride drops for their children and after 14–16 months, 65% of the group were still using the supplement

摘要:

AbstractThe relationship between pre‐ and post treatment DMFS measures in clinical trials of dentifrices may be quadratic rather than linear and, if linear, the slope may differ from one. Given either of these eventualities the traditional DMFS increment measurement does not utilize all the information available in the pre‐DMFS baseline score. If nonlinearity is present, analysis of multiple covariance with parameters derived from a polynomial regression is indica

摘要:

AbstractThe importance of a medical history to identify potential problems in dental management is self‐evident but the means of collecting medical data vary widely. This study has assessed the reliability of a self‐administered questionnaire (SAQ used by 292 randomly selected adult dental out‐patients (mean age 41.7 years) attending the oral medicine clinic of a dental leaching hospital. Results of the SAQ were compared with the history taken by receiving surgeons. Significant discrepancies were revealed not only in the SAQ but also in the history taken by the receiving surgeon, although the latter produced a more comprehensive record. Maximum yield of information regarding known medical problems was only produced by using the self‐administered questionnaire with a check of this by the receiving

摘要:

AbstractThere is a dose‐response relationship between the prevalence of the questionable category of dental fluorosis as reported by various authors and the drinking water fluoride level. While the possibility that chance could have produced this trend cannot be conclusively ruled out, a distinct pattern of increasing prevalence with increasing water fluoride level can be discerned. Such a pattern is not compatible with the concept of a threshold level for the act ion of fluoride ion on the enamel orga

摘要:

AbstractThe study was based on 164 twin pairs from the older cohort of the Swedish twin registry. The main purpose of the study was to analyze previously recorded data concerning gingival bleeding in members of twin pairs with differing smoking exposure. Other periodontal disease factors analyzed were plaque index, alveolar bone index and tooth loss. It was found that I he degree of alveolar bone loss and the number of teeth lost were greater in twins with a high life‐time smoking exposure than in I heir twin partners with a low life‐time exposure. Contrary to expectation, it was found that gingival bleeding propensity was less prevalent in the high exposure group. It is concluded that the validity of gingival bleeding as a sign and a symptom of inflammatory periodontal disease may be reduced as a consequence of smok

摘要:

AbstractThe prevalence of retained roots among Finnish adults was evaluated by examining a representative sample of 8000 Finnish adults aged 30 or older. The participation percentage was 89.6. Retained root was recorded when more than half the height of the tooth surfaces had been destroyed by caries. The reproducibility coefficient (kappa) for clinical recordings of retained roots was 0.79 for interexaminer cases and 0.65 for interexaminer cases. Fifteen pen cut of the subjects had one or more retained roots. Prevalence was twice as great among males as among females. The mean number of retained roots was 0.4 per subject. Of all teeth in the mouth, 4.4% had only the roots left. On the population level, some 343 000 adult Finns were estimated to have at least one retained root.
