Principles of surgical risk assessment of the elderly patient.

Treatment of the elderly will comprise increasingly higher proportions of practice time in the future, and issues regarding this treatment are more salient now than ever before. Because more elders are seeking treatment, surgeons need to be comfortable with assessing the potential risks associated with surgical procedures in their elderly patients, many of whom have multiple chronic diseases. Risks that need to be considered are those physiologic changes normal for aging, pathologic changes due to disease, and psychosocial changes that may occur with aging. This article assesses the contribution each of these changes makes to surgical risk, and discusses the principles of gerontology and geriatric medicine that are relevant to risk assessment.

Predictors of older adults' longitudinal dental care use. Ten-year results.

Our purpose was to identify factors predictive of reported dental care use by elders (65+) over a ten-year period in Massachusetts. The Massachusetts Health Care Panel Study began in 1974-75 (wave 1) as a statewide survey of 1625 noninstitutionalized elders. Wave 2 occurred in 1976, wave 3 in 1980, and wave 4 in 1985. The 540 persons who participated in all four waves are the subject of this report. The remainder either died, entered nursing home, or were lost to follow-up. This longitudinal design permits analysis of cohort, aging, and period effects. The outcome variables were self-reported dental care use within two years, or more than two years, as reported at waves 1, 3, and 4. Wave 2 was excluded because less than two years had elapsed since the previous wave. To identify factors predictive of reported use, we used a generalization of the logistic regression model that included a random effect term, which accounts for repeated measures being made on the same subjects. Covariates in the model were dentate status, education, income, cohort, sex, martial status, and time. The variable "time" served as a measure of aging/period effects. Persons were grouped into four birth cohorts. Before adjusting for other covariates, cohort was significantly associated with dental care use, but was not so in the full multivariate model. Dentate status, education, and income were significant predictors of use. The cohort effect was explained by dentate status, education, and income. Time was not significant, indicating no aging/period effects in this ten-year period, or that their net effect was zero.

Issues in financing dental care for the elderly.

The elderly make up an increasingly larger segment of the patient population in dental practices. This article reviews recent epidemiologic, demographic, and health services research, and concludes that significant segments of the elderly are at high risk for oral disease and/or limited access to dental treatment, and consequently warrant classification as high-risk groups for policy considerations. It then proposes policy options to the dental community and public decision makers. Oral care can be viewed as having three components. Two basic components are the primary care component--which includes diagnostic, preventive restorative, and periodontal care--and the acute care component--i.e., the treatment of oral pain, trauma, and infection. The third, rehabilitative component, has to do with the restoration of oral function, including prosthodontics and cosmetic dentistry. Viewing dental care in this perspective may help link funding for dental primary care services with that for other primary health services, and link restoration of function and improvement of quality of life with similar health services, like hearing, vision, and social services. In addition, approaching dental care policy makers on several levels--i.e., federal, state, and local--will contribute to our ability as a profession, in the decades ahead, to meet the oral health needs of more elders: including the frail, those at high risk for oral disease, and those with limited access to care.

'Ageism' in dental care delivery.

Older adults will comprise increasingly higher proportions of dentists' practice time in the future, and issues regarding their treatment are more salient now than ever before. Psychosocial issues and attitudes toward treating older patients are among the most important of these. Ageism, defined as negative attitudes or prejudice toward older adults, has implications in dental care delivery. It can be manifested by the attitudes that older people have toward their own aging process, by those who provide their health care, and by society. This article proposes a more appropriate definition of ageism, and discusses the forms ageism can take in the dental care setting.

Phenytoin sensitivity of fibroblasts as the basis for susceptibility to gingival enlargement.

A side effect of long-term administration of the anti-epileptic drug phenytoin is overgrowth of the connective tissues surrounding the teeth. In this in vitro study of protein and collagen synthesis by diploid fibroblasts from 17 nonepileptic young persons with healthy gingivae, only seven strains of cells responded to phenytoin in culture medium. Because not all phenytoin-treated individuals develop gingival overgrowth, we suggest that susceptibility is predicated upon the presence of a (genetically determined) phenytoin-sensitive subpopulation of gingival fibroblasts. The concept of the participation of sensitive cell subpopulations in other connective tissue disorders is supported by these findings.

Dietary implications of oral health decrements among African-American and white older adults.

OBJECTIVE: Older African-Americans are at disproportionate risk of chronic, nutritionally-related diseases. To begin to understand factors that may contribute to the disproportionate prevalence of life-threatening illnesses among African-Americans, this study investigates ethnic differences in the prevalence of oral health decrements. DESIGN: The Florida Dental Care Study (FDCS), a longitudinal study of changes in the oral health of 873 subjects age 45+, was used to explore a broad range of oral health status differences between African-Americans and White adults in the United States. The FDCS consists of clinical and self-reported measures of oral health, sociodemographic information, and other indicators of oral functional status. RESULTS: The prevalence of oral health decrements in this sample using a broad range of clinical and self-reported measures was substantial. African-American elders were at a heightened risk of poor oral health profiles, including having fewer teeth and being more likely to have a carious surface, fractured cusp or incisal edge, severely mobile teeth and severe periodontal levels than their White counterparts. Furthermore, the African-American respondents in our sample were significantly more likely to report a lower self-rated oral health and functioning than their White counterparts. These findings persist regardless of poverty status or educational level, two factors commonly thought to confound racial differences in health outcomes. CONCLUSION: Our study provides evidence that the widespread prevalence of oral health decrements and accompanying functional disability among this sample of dentate older adults impacts their daily lives. Of particular concern is the oral heath status of older African-Americans who may be nutritionally vulnerable due, in part, to these oral health decrements and disabilities. We suggest enhancing the access of health services in order to prevent those oral health decrements that presumably undermine adequate dietary intake.

Dental self-care among dentate adults: contrasting problem-oriented dental attenders and regular dental attenders.

Self-care behaviors are common and can act as substitutes for or supplements to formal health care services. We tested the hypothesis that problem-oriented dental attenders (POAs) report more dental self-care behaviors than do regular dental attenders (RAs), presumably as a substitute for professional care. The Florida Dental Care Study is a longitudinal cohort study of changes in oral health, in which we measured dental self-care behaviors related to three common dental problems: toothache pain, bleeding gums, and tooth loss. Despite using less dental care, POAs were less likely to report "conventional" methods as means to prevent the three dental problems; however, they were more likely to report that homemade remedies, topical medications, or mouthwashes were ways to prevent or treat these problems. POAs were also more likely to believe that "nothing can be done" to prevent these problems. Additionally, POAs had more negative dental attitudes, used less dental care during follow-up, had more dental disease, were the only persons who extracted at least one of their own teeth, and were more likely to use tobacco. With the exception of dental self-extractions, no single self-care belief or behavior distinguished POAs from RAs, nor were POAs likely to have different explanations for dental problems. Instead, the pattern was one of modest differences on a number of items. Although POAs use less dental care, they do not compensate by employing more "conventional" dental self-care behaviors, but report being more likely to employ "unconventional" behaviors. They also are more likely to believe that nothing can be done to prevent dental problems.

Coping with tooth pain: a qualitative study of lay management strategies and professional consultation.

This research analyzes transcripts of semi-structured interviews with patients presenting with tooth pain at a rural dental clinic in North Florida. The primary objectives are to identify the strategies patients use to manage their pain and to elucidate the decision-making process leading to the clinic visit. Although respondents understood that their condition was not self-limiting, only about one-half contacted the clinic within several days of the onset of their pain. Most tried one or more lay management strategies.

Twenty-four month coronal caries incidence: the role of dental care and race.

OBJECTIVES: To describe for a diverse sample of dentate middle-aged and older adults: (1) the 24-month incidence of coronal caries, and (2) its association with a broad range of clinical, behavioral, financial, attitudinal, and sociodemographic factors. METHODS: The Florida Dental Care Study is a prospective observational longitudinal cohort study of 873 persons who at baseline had at least 1 tooth and were 45 years or older. In-person interviews and clinical examinations were conducted at baseline and 24 months, with 6-monthly telephone interviews between those times. A multinomial logistic regression was done to predict whether a participant was in one of four mutually exclusive groups at the 24-month examination (new decay only [NDO]; new filling(s) only [NFO]; both new decay and filling(s) [BOTH]; or neither [NONE]). RESULTS: Only 33% of the 24-month participants were in the NONE group. There was no significant difference in caries incidence between regular attenders and problem-oriented attenders, regardless of whether teeth crowned at baseline, incident crowns, or incident root fragments were excluded. However, once differences in incident tooth loss and baseline clinical, behavioral, financial, and attitudinal differences were taken into account, regular attenders did appear to benefit by developing fewer coronal lesions and fewer dental symptoms than problem-oriented attenders. Baseline carious surfaces, filled surfaces, number of teeth, and bulk restoration fractures predicted caries incidence, but baseline cusp fractures did not. Persons with negative dental attitudes were more likely to be in the NDO and BOTH groups, and negative attitude toward brushing and flossing (but not their frequency) also predicted caries incidence. CONCLUSION: Certain baseline clinical conditions, approach to dental care, ability to pay for dental care, dental attitudes, race, and age group were predictive of coronal caries incidence, and regular attenders appeared to benefit from regular attendance.

Twenty-four month incidence of root caries among a diverse group of adults.

OBJECTIVES: (1) Describe for a diverse sample the 24-month incidence of root caries, and (2) test its association with a broad range of clinical, behavioral, financial, and sociodemographic factors. METHODS: The Florida Dental Care Study was a cohort study of randomly selected subjects who had at least 1 tooth and were 45 years or older at baseline. In-person interviews and clinical examinations were conducted at baseline and 24 months, with 6-monthly telephone interviews between those times; 723 subjects participated for both examinations. A multinomial logistic regression was done to predict whether the subject was in one of four mutually exclusive groups [new root decay only (NDO); new root filling(s) only (NFO); both new decay and new filling(s) (BOTH), or had neither (NONE)]. RESULTS: Thirty-six percent of subjects had at least 1 new root decayed and/or filled surface (DFS); 17% were in the NDO group, 14% in the NFO group, and 5% in the BOTH group. When limited to participants who had a nonzero increment, the mean (SD) DFS was 2.7 (2.9). Baseline clinical condition (presence of root decay, root filling(s), coronal decay, noncarious root defects, number of teeth present, percent of teeth with at least 4 mm of attachment loss) was predictive of moving from the NONE group into the NDO, NFO, or BOTH groups. The addition of behavioral, financial, and sociodemographic factors improved model fit. For example, regular dental attenders were significantly more likely to move from the NONE group into the NFO group, but regular attendance was not associated with a lower probability of moving from the NONE group into the NDO or BOTH groups. CONCLUSIONS: Root caries is a substantive dental health problem in this diverse sample of adults. These analyses demonstrate the utility of disaggregating caries incidence into four mutually exclusive groups for predictive models.

Factors influencing the effectiveness of mailed health surveys.

The authors investigated sources of bias in health surveys by examining responses to their 1989 questionnaire mailed to 1,255 Massachusetts men who were eligible for dental care provided by the Department of Veterans Affairs. After a maximum of three mailings and one telephone call to nonrespondents, a total of 1,049 veterans had responded out of 1,228 finally determined to be eligible, a response rate of 85 percent. The investigators found that small differences in univariate estimates would have occurred had the field phase been terminated after the first mailing, which had a response rate of 61 percent. To evaluate multivariate distributions, they duplicated their previously published logistic regression model for sources of dental care, using only those who responded to the first and second mailings. Although model fits would have been substantively the same had the field phase been terminated after the first or the second mailings, analysis of parameter estimates and their statistical significances suggested bias that would have led to different substantive conclusions, in some instances. Another potential source of bias in surveys was found to be item omission. Fifty-eight percent of respondents answered all 46 survey questions, and 90 percent answered at least 91 percent of the questions. Fewer questions were answered by those whose responses were received last, but trends regarding missing data by age or education were not statistically significant. Although the survey using this methodology met all objectives, subject nonresponses, the ineligibility of potential respondents, item nonresponses, and skewed distributions of outcome variables combined to reduce the statistical power to detect differences among groups or to alter the analysis of the differences. These factors need to be planned for by investigators undertaking similar surveys.
