Dental care utilization among North Carolina rural older adults

Objectives: This analysis delineates the predisposing, need, and enabling factors that are associated with regular and recent dental care in a multiethnic sample of rural older adults. Methods: A cross-sectional, comprehensive, oral-health survey conducted with a random, multiethnic (African American, American Indian, white) sample of 635 community-dwelling adults aged 60 years and older was completed in two rural southern counties. Logistic regression models assessed the simultaneous associations of dental care with predisposing, enabling, and need factors. Results: Almost no edentulous rural older adults received dental care; 27.1 percent of dentate rural older adults had received regular dental care, and 36.7 percent had received recent dental care. Predisposing (less than high-school education, dental anxiety), enabling (no regular place for dental care), and need factors (no filled teeth) reduced the odds of regular dental, while predisposing (dental anxiety), enabling (no regular place for dental care), and need factors (no filled teeth) reduced the odds of recent dental care. Having excellent, very good, or good self-rated oral health increased the odds of receiving regular and recent dental care. Conclusions: Regular and recent dental care are infrequent among rural older adults. Contrary to expectations, those not receiving dental care are those who most need care; this has been referred to as the Paradox of Dental Need. Community access to dental care and the ability of older adults to pay for dental care must be addressed by public-health policy to improve the health and quality of life of older adults in rural communities.     

Changing dentate status of adults, use of dental health services, and achievement of national dental health goals in Denmark by the year 2000

OBJECTIVES: This study analyzes the current profile of dentate status and use of dental health services among adults in Denmark at the turn of the millennium, assesses the impact on dentate status of sociodemographic factors and use of dental health services in adulthood and in childhood, and highlights the changes over time in dental health conditions among adults. Finally, the intention of the study was to evaluate the Danish dental health care system's level of achievement of the official goals for the year 2000 as formulated by the World Health Organization and the National Board of Health. The subjects of this study included a national representative sample of 16,690 Danish citizens aged 16 years and older (response rate=74.2%). A subsample (n=3,818) took part in a survey of dental care habits in childhood and prevalence of removable dentures; 66 percent of persons selected responded. METHODS: Personal interviews were used to collect information on dentate status, use of dental health services and living conditions; data on dental care habits in childhood and prevalence of removable dentures were collected by self-administered questionnaires. RESULTS: In all, 8 percent of interviewed persons were edentulous, while 80 percent had 20 or more natural teeth. At age 65-74 years, 27 percent were edentulous and 40 percent had 20 teeth or more; 58 percent wore removable dentures. Dentate status and prevalence of dentures were highly related to educational background and income, particularly for older age groups. Among persons interviewed, 80 percent paid regular dental visits and visits were most frequent among persons of high education and income. At age 35-44 years 95 percent had participated in regular dental care in childhood compared to 49 percent of 65-74-year-olds. Multivariate analyses revealed that sociobehavioral factors had significant effects on dentate status. CONCLUSIONS: Compared to similar studies carried out in 1987 and 1994, the present survey indicates a positive trend of improved dentate status in adult Danes in general and regular use of dental health services increased considerably over time. The WHO goals for better dental health by the year 2000 were achieved for 35-44-year-olds, whereas the goal of more people with functional dentitions at age 65 years or older was not achieved. It remains a challenge to the Danish dental health system to help even out the social inequalities in dental health.     

Clinical correlates of dental anxiety among older adults

Most studies of the relationship between dental anxiety and oral health status have used subjective rather than clinical indicators of oral health. In this paper we examine differences between older adults who are and are not dentally anxious using a broad range of clinical measures. The data show that dentally anxious individuals were more likely to be edentulous, and among the dentate, had more missing and fewer filled teeth. As a result, dentally anxious dentate subjects were more likely to need prosthodontic treatment. They were also more likely to need immediate treatment for the relief of pain and infection and periodontal care. There was evidence to suggest differences in patterns of dental treatment between those who were and were not dentally anxious and some evidence consistent with the hypothesis that aging influences the relationship between dental anxiety and oral health status.     

Three factors predicting irregular versus regular dental attendance: A model fitting to empirical data

A tentative theory, based upon the results of a survey that was performed in an urbanized village in the Netherlands, and proposing that the (ir) regularity of dental attendance is predicted by 1) dental anxiety, 2) the family dental health pattern and 3) the preference for preservation of the teeth, has been explored with loglinear models (logit approach). It has been shown that dental anxiety in combination with preference for preservation of the teeth is significantly associated with the (ir)regularity, but the family dental health pattern has a modifying effect. The probabilities of being an irregular dental attender were estimated for the levels discernible in the two predictor variables and with the odds of irregular dental attendance corresponding 95% confidence intervals were approximated. The results were discussed and it seems warranted to conclude that (ir) regular dental attendance dependent on the levels of the variables, mentioned above, is predicted more or less accurately. A further exploration of the theory and the variables involved seems worthwhile.     

Dental fear and anxiety in an older adult population

A random sample of 580 people aged between 50 and 89 yr completed a questionnaire containing two measures of dental fear and anxiety. One of these was Corah's Dental Anxiety Scale (DAS) and the other a scale derived from the Structured Interview for Assessing Dental Fear (SIADF). The mean score on the DAS was 7.8, and 8.4% of subjects were classified as dentally anxious. There were no differences in mean DAS scores by sex but significant differences by age, with younger individuals having higher scores (P less than 0.0001). The edentulous had significantly higher scores than the dentate (P less than 0.001). Scores on the SIADF scale were higher among younger individuals (P less than 0.0001), the edentulous (P less than 0.01) and women (P less than 0.05). Older adults who were dentally anxious were less likely to report a regular source of dental care and a dental visit in the previous year and more likely to report having avoided or delayed dental treatment. Possible explanations of higher dental anxiety scores among younger persons and the edentulous are reviewed.     

Relationship between clinical dental status and eating difficulty in an old Chinese population

This study investigated the relationship between clinical dental status and eating difficulty in a sample of older Chinese people in Guangxi, China. Sample was selected from people aged 55 years and older who had routine annual health check-ups at a large hospital health centre. The sample consisted of 1,196 dentate people who had clinical oral examinations and face-to-face interviews. Different measures, namely the Index of Eating Difficulty, dissatisfaction with chewing ability and ease of eating certain foods were used to measure eating difficulty. Multiple logistic regression analysis showed that after controlling for the effects of age, sex, occupation, self-assessed social class and self-perceived general health, increased eating difficulty was significantly related with having fewer teeth, fewer posterior and anterior occluding pairs of teeth (both natural teeth only and natural plus replaced teeth), more unfilled posterior spaces, more unfilled anterior spaces, mobile teeth, decayed teeth and roots. In conclusion, clinical dental status was strongly related with eating difficulty in a sample of older Chinese dentate people.     

Orofacial esthetics and dental anxiety: Associations with oral and psychological health

Objective. Severe dental anxiety (DA) is associated with both oral health and psychosocial consequences in what has been described as a vicious circle of DA. The aim of this study was to investigate self-rated orofacial esthetics in patients with DA and its relationship to psychological and oral health. Materials and methods. A consecutive sample of 152 adult patients who were referred or self-referred to a specialized dental anxiety clinic filled out the Orofacial Esthetic Scale (OES) as well as measurements on DA, self-rated oral health and general anxiety and depression. Clinical measures of dental status were also obtained. Results. Compared with the general population, patients with DA had lower ratings of satisfaction on all aspects of their orofacial esthetics, which included the teeth, gingiva, mouth and face, as well as a global orofacial assessment. Furthermore, the perception of the orofacial appearance was related both to dental status and self-rated oral health, as well as to general anxiety and depression. The level of dissatisfaction with the orofacial appearance was similar for both genders, but women reported more regular dental care and better dental status. Conclusions. The results of this study clearly show less satisfaction with dental and facial appearance in patients with DA, and that the self-rating of orofacial esthetics is related to both oral and psychological health. The OES can be used to assess orofacial esthetics in patients with DA.     

Association between dental fear and dental attendance among adults in Finland

OBJECTIVE: Our aim was to evaluate the association between dental attendance and dental fear while considering the simultaneous effects of perceived oral health and treatment need, satisfaction with oral health services, age, gender, marital status, and attained level of education. MATERIAL AND METHODS: The two-stage stratified cluster sample (n=8028) represented Finnish adults aged 30 years and older. The response rate to this nationwide sample was 88%. Dental fear was measured with the question: "How afraid are you of visiting a dentist?" Multiple logistic regression analyses were used to determine the association between dental fear and dental attendance, including the following independent variables: perceived oral health, perceived treatment need, satisfaction with oral health services, age, gender, marital status, and attained level of education. RESULTS: Among all ages, except 30 to 34-year-olds, irregular attenders were more likely to be very afraid of visiting a dentist than regular attenders were. The association was stronger the older the age group. Only age modified the association between dental fear and attendance. Irregular dental attendance can be attributed to high dental fear (etiologic fraction among exposed) in 41% of cases. CONCLUSION: Reducing dental fear would increase the number of regular attenders, especially among older age groups. Individuals for whom oral health services have been provided regularly since childhood seem to continue to use these services regularly despite high dental fear.     

Tooth loss and dental caries in institutionalized elderly in Italy

An epidemiological survey of dental health status and needs was conducted in a group of 234 randomly selected institutionalized elderly people in Naples, Italy. The mean age of the patients was 81.4 yr, 71.4% were women and 28.6% men. A total of 140 (59.8%) people were totally edentulous; an additional 13.7% were edentulous in one jaw. A significant increase in prevalence of edentulousness with increasing age was recorded. 44.3% of the edentulous in both jaws wore complete dentures. The mean number of remaining sound teeth, decayed teeth and root remnants in the elderly with maxillary and mandibular natural teeth decreased with increasing age. Of the 94 dentate elderly, 29.8% had no need of dental treatment. Of all dentate patients 68.1% needed one or more dental extractions with a mean need of 3.9 per patient; 37.2% needed restorative treatment for one or more teeth with a mean need per patient of 2.9. Analysis of the results showed poor dental health in this target group and the necessity of improving the dental health services programs for the elderly living in institutions.

Dental anxiety and oral health outcomes among rural older adults

Objectives: The objective of this study is to determine the degree to which rural older adults are able to complete a measure of dental anxiety and to assess the prevalence, as well as the demographic and oral health characteristics, of individuals reporting high dental anxiety. Methods: A population‐based sample of 635 African American, American Indian and White older adults (age ≥60 years) completed an in‐home survey, and 362 dentate participants completed an oral examination. Dental anxiety was measured using the four‐item Corah's Dental Anxiety Scale (DAS). Gender, ethnicity, age, education, and oral health outcomes were compared between those who completed all four DAS questions (completers) and those who did not (noncompleters) as well as, among completers, those with high versus low DAS scores. Results: There were 94 (14.8%) noncompleters. Noncompletion was associated with older age, lower education, being edentulous, and having gingival recession. 12.4% of DAS completers had high DAS scores, which was more common among those aged 60‐70 years, women, and those with oral pain and sore or bleeding gums. In logistic regression analysis, only sore and bleeding gums had a significant association with a high DAS score (odds ratio = 2.40, 95% confidence interval 1.09‐5.26). Conclusions: About one in eight rural older adults have high dental anxiety, which is associated with poor oral health outcomes. Identifying new approaches to measure dental anxiety among a population with limited interaction with dental care providers is needed.     

Dental anxiety, the parental family and regularity of dental attendance

A survey was carried out among 25-yr-old inhabitants of Amsterdam in order to study the relationship between regularity of dental attendance on the one hand and dental anxiety, dental upbringing of the respondents, dental behavior of the parents, education, sex, and the interactions between these independents, on the other. The data were analyzed hierarchically with regression analysis, the logistic approach. Dental anxiety, sex, dental upbringing and the interaction between education and anxiety, in that order, were found to be of importance for the prediction of regularity of dental attendance. Two other terms, though lacking substantial standardized regression coefficients, namely education and the interaction between education and dental upbringing, are also present in the model found. The prediction of one being a regular attender is satisfactory, but the classification of the irregular attenders is disappointing. The effect is discussed of the rather large non-response and attention is given to the effect of dental upbringing in regard to coping resources in the dental situation. It has to be concluded that other factors must be included to achieve an improvement of the classification of the irregular attenders. Dental anxiety, although of importance, cannot account for an adequate differentiation between regular and irregular attenders.     

Oral health among white, black, and Mexican-American elders: an examination of edentulism and dental caries

Objectives: To examine racial/ethnic disparities in oral health among older Americans. Methods: Differences in frequency of edentulism and number of decayed, missing, and filled teeth were assessed in 2,679 non‐Hispanic white, 742 non‐Hispanic black, and 934 Mexican‐American individuals aged 60 and older from the National Health and Nutrition Examination Survey (1999‐2004). Results: Controlling for potential confounding variables, blacks and Mexican‐Americans had significantly higher numbers of decayed teeth but fewer numbers of filled teeth than whites. Although blacks had a lower likelihood of being edentulous than whites, dentate blacks had a higher number of missing teeth. Compared with whites, Mexican‐Americans were less likely to be edentulous, and dentate Mexican‐Americans had fewer missing teeth. Our study also showed that blacks and Mexican‐Americans had less frequent dental checkups than whites. Conclusions: Oral health disparities are persistent across racial/ethnic groups for older Americans despite the fact that the differences between groups typically diminish when socioeconomic, health‐related, and behavioral factors are considered in the models. Our study suggests that reducing racial/ethnic oral health disparities requires multiple clinical approaches.     

Dental fear and subjective oral impacts among adults in Finland

We aimed to study the association between subjective oral impacts and dental fear adjusted for age, gender, level of education, and dental attendance, and to evaluate whether this association was modified by the number of remaining teeth. Nationally representative data on Finnish adults, 30+ yr of age (n = 5,987), were gathered through interviews, clinical examination, and questionnaires. Dental fear was measured using the question: ‘How afraid are you of visiting a dentist?’ and subjective oral impacts were measured using the 14‐item Oral Health Impact Profile (OHIP‐14) questionnaire. The outcome variables were the percentage of people reporting one or more OHIP‐14 items fairly often or very often, and the ‘extent’ and ‘severity’. Those with high dental fear reported higher levels of prevalence, ‘extent’, and ‘severity’ of subjective oral impacts than did those with low dental fear or no fear. The association between dental fear and subjective oral impacts was not significantly modified by the number of remaining teeth. The greatest differences between those with high dental fear and low dental fear were found in psychological, social, and handicap dimensions, but not in functional or physical dimensions of the OHIP‐14. Treating dental fear could have positive effects on subjective oral impacts by reducing psychological and social stress and by improving regular dental attendance and oral health.     

Anxiety and depressive disorders and dental fear among adults in Finland

Pohjola V, Mattila AK, Joukamaa M, Lahti S. Anxiety and depressive disorders and dental fear among adults in Finland.
Eur J Oral Sci 2011; 119: 55–60. © 2011 Eur J Oral Sci We studied the association between dental fear and anxiety or depressive disorders, as well as the comorbidity of dental fear with anxiety and depressive disorders, controlling for socio‐demographic characteristics, dental attendance, and dental health. Nationally representative data on Finnish adults, ≥ 30 yr of age (n = 5,953), were gathered through interviews and clinical examination. Dental fear was measured using the question: ‘How afraid are you of visiting a dentist?’ Anxiety and/or depressive disorders were assessed using a standardized structured psychiatric interview according to criteria presented in the Diagnostic and Statistical Manual of Mental Disorders (4th edition) (DSM‐IV).Those with depressive disorders, generalized anxiety disorder or social phobia more commonly reported high dental fear than did those without these disorders. When age, gender, education, dental attendance, and the number of decayed, missing, and restored teeth were considered, those with generalized anxiety disorder were more likely to have high dental fear than were participants with neither anxiety nor depressive disorders. The comorbidity of depressive and anxiety disorders also remained statistically significantly associated with dental fear; those with both depressive and anxiety disorders were more likely to have high dental fear than were those without these disorders. Our findings support the suggestion that some individuals may have a personality that is vulnerable to dental fear.     

The prevalence and experience of oral diseases in Adelaide nursing home residents

BACKGROUND: The twenty-first century will see the evolution of a population of dentate older Australians with dental needs very different from those of older adults in past years. This study provided comprehensive information concerning oral disease prevalence in older South Australian nursing home residents. METHODS: This paper presents cross-sectional baseline results. RESULTS: Most of the 224 residents, from seven randomly selected nursing homes, were functionally dependent, medically compromised, cognitively impaired and behaviourally difficult older adults who presented many complex challenges to carers and to dental professionals. Two-thirds (66 per cent) were edentulous with many dental problems and treatment needs. Dentate residents had a mean of 11.9 teeth present, higher than previously reported. The prevalence and experience of coronal and root caries and plaque accumulation was very high in dentate residents; especially males, those admitted more than three years previously, those who ate fewer food types and those who were severely cognitively impaired. These residents had more retained roots, decayed teeth and missing teeth, and fewer filled teeth when compared with data for community-dwelling older adults. CONCLUSIONS: This study highlighted the poor oral health status of these nursing home residents and the great impact of dementia on their high levels of oral diseases.     

Irregular users of dental services among Norwegian adults

In 1979-80 a nationwide random sample of 1511 Norwegians, aged 16-79 years, were asked a series of questions about dental health and related factors (behavior, attitude, knowledge, social network, interpersonal communication, and 'health locus of control'). The purposes of the study were to describe the irregular users of dental services and to find mutable factors that could distinguish the regular from the irregular users. 17.4% of the dentate women and 21.7% of the men reported visiting the dentist less than once a year. Among the background variables, age and income/education were the most powerful predictors of use of dental services. Different patterns of behavioral characteristics were found among women as compared with men. The mutable factors that made a significant distinction between the regular and irregular users were use of interdental remedies, use of fluoride, social network, and health attitude (only among women). To a great extent, sociopsychologic and behavioral factors seemed to act through the demographic and economic variables in predicting the regularity of dental attendance.     

Dental attendance and dental status

This article examines the relationship between differences in dental attendance patterns and variations in dental status. A sample of 336 dentate men and 110 dentate women were selected at random from employees of two industrial plants in N.W. England in 1980. They were given a dental examination and asked about visits to the dentist. Regression analysis showed that while the more frequent the dental visits, the lower the rate of tooth loss and the fewer the number of teeth with active decay, the higher, however, the average number of fillings. There were significant differences, moreover, between manual and non-manual workers, the former being more likely to lose their teeth and the latter to have their teeth filled, at each given age and frequency of dental visit. Though the more frequent dental attenders had the advantage over the less frequent of having, on average, a higher number of functioning teeth, restored or otherwise sound, they also had the disadvantage of having higher levels of treated disease and thus of disease experience. The results suggest that while frequent dental visits help to postpone tooth loss and to maintain dental function, they do not apparently help to prevent the onset of further disease.
