Dental health among workers at a Danish chocolate factory

All workers (n = 59) at a Danish chocolate factory were given a questionnaire in order to study dental health behavior and self-assessment of dental health. Regular dental visits at least once a year was reported by 71% of the respondents. Toothbrushing at least twice a day was claimed by most of the workers, but only a few reported to brush their teeth daily at work. One fourth declared that they often consumed chocolate at their working place. Good dental and gingival conditions were only reported by 25% and in correspondence with this, nearly one third claimed to have had much or a great deal of trouble with their teeth. Mean DMFS increased from 22.7 in the age group 16-19 yr to 106.7 among persons 40 yr of age or more. In the age group 20-39 yr half of the teeth present had gingivitis and calculus and among the older individuals half of the teeth had gingivitis and pockets deeper than 5 mm. Chocolate workers were considered a high risk group.     

Dental health habits of young families from Southwestern Finland

Abstract – The dental care habits of parents and children as well as the associations of these habits were investigated in a follow-up study conducted in the Southwest of Finland. The background factors of the child's use of night-time juice were also studied. The families of the study were a representative sample of local young families with their first child. The study sample was obtained using stratified randomized cluster sampling and confidential questionnaires. Both the mother's and the father's toothbrushing habits were significantly associated with the child's toothbrushing habits with a cumulative effect. The mother's use of sugar was significantly associated with the child's sugar use habit. Infectious diseases at the age of 9–17 months had an increasing effect on the use of juice at night. Fathers and the youngest mothers, especially, need additional support not only for the demanding task of the upbringing of their child but also for the care of their own teeth.     

Dental caries risk indicators among Australian Aboriginal young adults

Jamieson LM, Roberts‐Thomson KF, Sayers SM. Dental caries risk indicators among Australian Aboriginal young adults. Community Dent Oral Epidemiol 2010; 38: 213–221. © 2009 John Wiley & Sons A/S Abstract – Objectives: To determine dental caries risk indicators among a birth cohort of Australian Aboriginal young adults (n = 442). Methods: Data were from the Aboriginal Birth Cohort study, a prospective longitudinal investigation of Aboriginal individuals born 1987–1990 at an Australian regional hospital. Models representing demographic, socioeconomic, behavioural, dental service utilization and clinical oral health variables were tested using multivariate regression. Results: The percent DT > 0 was 72.9 (95% CI 68.7–77.1), mean DT was 4.19 (95% CI 3.8–4.6), percent DMFT > 0 was 77.4 (95% CI 73.5–81.3) and mean DMFT was 4.84 (95% CI 4.4–5.3). After controlling for other covariates, risk indicators for percent DT > 0 included soft drink consumption every day or a few times a week (PR 1.25, 95% CI 1.08–1.45), not consuming milk every day or a few times a week (PR 1.16, 95% CI 1.04–1.30) and sweet consumption every day or a few times a week (PR 1.18, 95% CI 1.04–1.33). Risk indicators for mean DT included sweet consumption every day or a few times a week (B = 1.14, 95% CI 0.27–2.02), nonownership of a toothbrush (B = 0.91, 95% CI 0.10–1.87) and presence of plaque (B = 2.46, 95% CI 0.96–3.96). Those with 4 + occupants in their house the previous night had 1.2 times the prevalence of having DMFT > 0 than their counterparts with less household occupants (95% CI 1.01–1.49). Percent DMFT > 0 was also associated with consumption of soft drink every day or a few times a week (PR 1.18, 95% CI 1.04–1.34) and consumption of sweets every day or a few times a week (PR 1.23, 95% CI 1.10–1.37). Mean DMFT was higher among those who consumed sweets every day or a few times a week (B = 0.13, 95% CI 0.05–0.22) and who had dental anxiety (B = 0.10, 95% CI 0.01–0.19). Conclusions: In an Australian Aboriginal young adult cohort, risk indicators for dental caries included social determinants such as household size, dietary behaviours such as regular consumption of soft drink and sweets, dental behaviour such as nonownership of a toothbrush and dental anxiety.     

Dental health behavior and attitudes – an application of correspondence analysis

Differences in dental behavior and dental attitudes between people with (almost) all natural teeth, people with a full denture in both jaws and people with a full denture in only the maxilla are visualized by means of correspondence analysis in one overall picture. In this picture the three distinguished subgroups of dental patients and their characteristics are indicated as points in a two-dimensional space. The distances between the points in this picture show to what extent these points are connected. The findings obtained in this study can lead to the conclusion that: a. differences in dental status are related to differences in dental behavior and dental attitudes; b. people with all natural teeth and people with a full denture in both jaws obviously are opposite of each other in many respects, whereas people with a full denture in only one jaw can be characterized as a dental in-between group.     

Oral health and factors related to oral health in Polish schoolchildren

The oral health and factors related to oral health were surveyed in 168 schoolchildren, aged 10-12 years, attending one school in Warsaw. The children were examined for dental caries and gingival status, dental plaque and salivary Streptococcus mutans and Lactobacillus counts. An interview on dietary habits and use of fluoridated toothpaste was also performed. The results showed a mean DMFT of 4.7 in the sample. Gingival Index 1 and Plaque Index 3 were median scores for the majority of the children. S. mutans was demonstrated in 94% of the children and high numbers were found in 15%. Lactobacillus sp. were present in all examined children, with high counts in 56% of the subjects. The interview revealed that most of the children eat five or six times per day and consume candies or cakes each day. Fluoridated toothpaste was not used regularly by any of the children. In conclusion this study shows a high prevalence of dental disease and an unfavorable combination of etiologic factors.     

Dental health behavior in a migrant perspective: use of dental services of Pakistani immigrants in Norway

The purpose of the present study was to assess the utilization pattern of dental services in a group of Pakistani immigrants in Norway. Use was related to sociodemographic characteristics, level of urbanization in Pakistan, knowledge and belief about dental diseases and evaluated and perceived dental health. A total of 160 immigrants were clinically examined and interviewed by a structured questionnaire. The effect change analysis was performed, and separate analyses were performed for men and women. Altogether 60% had visited the dentist during the last 3 yr. While 69% coming from the cities had been to the dentist in Norway, this was the case for only 38% of those from the villages of Pakistan. Pain was given as the main reason for dental visits, and the data indicated insufficient ability to perform self-assessment of own dental health. The independent variables could explain more of the variance in use of dental services among the Pakistani men (R2 = 40%) than among the women (R2 = 21%). While number of decayed teeth and level of urbanization were among the strongest predictors among the men, dental behavior in Pakistan and number of years in Norway were of importance among the women. The latter variable indicated that the women in terms of dental behavior had a higher degree of acculturation than the men, leading to a change in traditional health behavior.     

Dental health in Dutch drug addicts

Abstract The aim of this study was to describe the Dental health status of a group of Dutch 20–40-yr-old drug addicts (n=121) and to compare the results on DMFS with data of an age-comparable sample of the general adult population in the Netherlands (n=1532). Mean DMFT of the addicted group was 16.9. ANOVA showed that the mean DMFS of the addicted group differed statistically significantly from the DMFS of the general population of the same age (= 52.1 versus 38.9). Statistically significant differences in DMFS were also found between the various age groups. The percentage of addicted subjects with more than cervical plaque on one or more teeth was 76.5%, 82.4% and 88.2% in the three youngest age groups. In almost all addicted subjects, bleeding of the gingiva was present. Only 36% had visited the dentist less than a year ago and 18% brushed their teeth less than once a day. It is concluded that there is a large gap in dental health status and behavior between drug addicts and the general population. Dental care as an integral part of the care for drug addicts is advocated.     

Dental health education through home visits to mothers with young children

In 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 attitudes 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 supplements.     

Dental health status and attitudes to dental care in families participating in a Danish fluoride tablet program

The caries experience and dental fluorosis of 84 Danish children, who had used fluoride tablets for 1-4 yr in the period 1976-80, were compared with those of a group matching in sex, age, place of living, and socioeconomic status. The average age of the children at the time of examination was 5.8 yr. A recording of mothers' attitudes to dental care, knowledge about tooth brushing, attitudes to candy, and number of teeth in the maxilla showed no difference between the fluoride tablet group and the non-users' group. Moreover, there was no significant difference between the two groups with respect to dental caries. The findings are discussed in relation to recent reports on the decline of dental caries resulting from widespread use of local administration of fluorides.     

Dental health in a group of drug addicts attending an addiction-clinic

The present study was undertaken to investigate the dental health of a group of parenteral drug addicts. The study population comprised 134 persons with a mean age of 25 yr (min. 18, max. 37) examined in 1977-81. Mean DMFT was 18.3 and mean DMFS was 50.2, approximately twice as much as found in comparable age groups in Denmark. Even free smooth surfaces were often involved. The oral hygiene was measured by the use of the Visible Plaque Index (VPI) and the Bleeding Index (BI). Both indices were high, mean VPI = 77.4 and mean BI = 71.3. 12-40% of the teeth selected had a loss of periodontal attachment of more than 4 mm. It is suggested that not only drug abuse, but also factors like low social status, low education and different barriers towards receiving dental treatment should be considered in a multifactorial cause-effect relationship. The effect of offering a free dental care system for this high-risk group will be dealt with in another paper.     

Dental health of 9–10-year-old mentally retarded children in Eastern Finland

Abstract All 9–10-year-old children in one Finnish county were screened with a standardized set of tasks for their mental performance. 58 verified mentally retarded and 58 randomly selected healthy children were examined for dental and gingival status and level of oral hygiene Comparisons were made between the retarded and the healthy, as well as between subgroups of the retarded. Similar DFS-values, higher DS-values and an inferior level of oral hygiene in terms of VPI were found in mentally retarded when compared with healthy children. No evident difference was found in gingival status (by GBI) between the retarded and the healthy. The mildly or moderately retarded found by the screening and not yet included in special welfare had the highest DFS-scores, the highest prevalence of untreated caries and the poorest gingival health among the retarded.     

Dental health practices in Norwegian adults

Abstract A nationwide sample of 1511 Norwegian adults were interviewed in 1979–80 concerning health habits, including dental habits. While daily toothbrushing and regular treatment attendance appeared to have become the rule among young and middle aged individuals, use of dental floss and especially of fluoride tablets or rinses, still are the exception. Dental health habits were clustered around the variable treatment attendance with slightly different patterns for men and for women. Measures of sugar consumptions were only slightly correlated with background variables and dental health behavior. While the latter was socially dependent, consumption of sugar probably was attached to personal characteristics or situational factors. The correlations between dental health behavior and other health behavior practices were generally weak, and somewhat different for men and women. Two separate types of motives for preventive behavior were distinguished between: health motives and cosmetic motives.     

Dental fear among a young adult Saudian population

AIMS: To assess the prevalence of dental fear and reasons for irregular dental attendance among young adult university students; to describe the gender distribution of the dentally anxious population according to the perceived origins or sources of fear; to identify the time of fear development and preference for anaesthesia or sedation before dental treatment. METHOD: A questionnaire incorporating the Dental Fear Scale (DFS) with items related to sources of dental fear stimuli, together with the preference of anaesthesia or sedation before dental treatment and other characteristics. Approximately 500 questionnaires were distributed among Saudian undergraduate students. RESULTS: 368 questionnaires were completed and presented for statistical analysis. The sight and sensation of anaesthetic needles and the sight, sound and sensation of the drill were rated the most fear-eliciting stimuli. Also, females tended to be more anxious than males. Increased heart rate was the most common reported physiological response to fear resulting from dental treatment. The overall level of fear of dental work among the studied population was found to be about 39%.'Lack of time' and 'no need for treatment' were found to be the main reasons for irregular dental visits. Fear of pain and trauma were the major perceived sources of reported fear reactions and were developed mainly during childhood. About 63% of the subjects preferred to have local anaesthesia before dental treatment to prevent or ameliorate dental fear.     

Dental fear and oral health habits among adults in Finland

A previous clinical trial showed that long-term use of saliva-stimulating polyol (xylitol and sorbitol) chewing gums was associated with arrest of dental caries in young subjects. After a 20-22-month intervention (when the subjects were 8 years old), a total of 23 primary teeth with extensive dentin caries lesions whose surface in clinical examination was found to be totally rehardened (remineralized) could be removed because the teeth were near their physiologic exfoliation time. These teeth were subjected to histologic, microhardness, and electron microscopic tests. The majority of the specimens had been remineralized from the surface by a non-cellular-mediated process within the remaining collapsed, organic extracellular matrix associated with the remaining dentinal surface. Many of the underlying dentinal tubules were filled with a matrix that had been subsequently mineralized. Dental microanalyses showed that the topmost (outer) 20-mm-thick rehardened layer of the lesions exhibited the highest Ca:P ratio, which leveled off at a depth of approximately 150 mm. The rehardened surface layer (normally <0.1 mm in thickness) was significantly (P < 0.001) harder than sound dentin and nearly as hard as sound enamel. Although the main source of the mineral present in the rehardened layer was most likely of salivary origin, some extracellular remineralization was probably mediated by odontoblasts. The results complete the clinical diagnoses of the original trial and suggest that regular use of polyol chewing gums may induce changes in dentin caries lesions, which in histologic and physiochemical studies show typical characteristics of rehardening and mineralization.     

Dental health promotion in a group of children at high risk to dental disease

Three hundred and ten children from three schools were examined before and after a dental health promotion program targeted at one of the schools. Parents of subjects at the experimental school were visited at home by a community health worker who provided individualized information on dental services and preventive strategies. Parents of subjects at the control school were provided with similar information by way of general written documentation, not tailored to specific needs, and distributed as part of the traditional school take home system. The experimental hypothesis proposed that, at re-examination, subjects from the experimental school would show a measurable improvement in caries increment, and a reduced plaque index over subjects from the control schools. Although the individualized social intervention strategy did not demonstrate a major shift in use of dental services or improvement in health status some improvement in caries experience was obtained in the target group. The multifactorial nature of dental disease and the limited contact of the health worker with the families involved would account for the low success rate of this strategy.     

Dental anxiety in young adult Danes under alternative dental care programs

Abstract – The purpose of the present report is to establish to what extent dental anxiety is expressed by young adults with a long history of regular dental care, to analyze whether expressions of dental anxiety vary during young adulthood in response to different dental care delivery programs, and to study which factors might account for existing expressions of dental anxiety. The study comprised 697 persons who participated in a longitudinal study on alternative dental care programs, running from the youngsters' 16th to their 19th yr. At the end, Corah Dental Anxiety Scale (DAS) was applied through self-completed questionnaires. Overall DAS-mean was 7.26; women expressed more anxiety than men (7.73; 6.78). Significant association between anxiety expressed at the end and at the start of the study indicated that dental anxiety was probably present at an early age. No association was found with utilization of dental services, A multiple regression analysis indicated early expressed dental anxiety and negative self assessment of dental health as important predictors for dental anxiety, while sex, negative assessment of gingival health, and dental program were of less importance, altogether explaining 22% of the DAS score variation. The risk group concept currently employed by the Public Child Dental Health Services might be extended to include expressions of dental anxiety.     

Associations of self-reported dental health and general health measures in the Rand Health Insurance Experiment

Data from the Rand Health Insurance Experiment (HIE) are used in exploratory analyses to examine the associations of self-reported dental health with general health measures. Responses of 1658 dentulous participants 18-61 yr of age are examined. Patterns of association among and between items of the physical, mental, social, and general health indices and a three-item measure of self-reported dental health are tested using principal component analyses. Findings suggest that dental health represents a separate dimension of health that is not fully accounted for by other health measures. However, while dental health may be considered an independent health construct, the dental health index was weakly but statistically significantly associated with the general health perceptions index and, to a lesser extent, to the mental health index and the two physical health indices. Improved self-reported measures of dental health status, studied in association with other general health measures, will allow us to better define oral health, and patients' perceptions of oral health, particularly in relation to other general health perceptions. In addition, a valid and reliable multidimensional oral health measure would be valuable as a potential cost-effective method of epidemiologic data collection, as well as a tool for evaluating the effectiveness of oral health interventions, and for providing data for dental health policy making and planning.
