As the U.S. geriatric population grows older, dentists should recognize the need to carefully consider age-related concerns that influence clinical decision-making. The authors discuss several prevalent problems typically found in "old-old" patients and propose a model for determining the appropriate extent of dental care for them.
Periodontal disease studies in developing countries over the past four decades indicate periodontitis to be a major problem, even in populations with relatively low caries rates. The aim of this study was to document levels of periodontal treatment needs, as well as oral hygiene levels for a large sample covering all ages of an Ethiopian Jewish population recently immigrated into Israel. Over 800 subjects from the total of 15,000 Ethiopians who immigrated were examined utilising the PTNS Index and the OHI-S Index. Results indicate that all the examined population was in need of oral hygiene instruction. Almost 80 per cent are in need of scaling and approximately 20 per cent are in need of more complex treatment such as surgery. Significant differences were found according to age. This could be attributed to the high OHI-S scores, ranging from 2.53 at age 0-12 to 4.82 at the 51+ age group, with a mean Debris Index of 2.12 for the total population. It is suggested that this population should be exposed immediately to preventive and treatment programmes to improve oral hygiene and decrease needs for future, costly periodontal treatment.
Studies have documented the prevalence of caries in developing countries. The current study adds to this body of knowledge. Of the total Ethiopian Jewish population who emmigrated to Israel in 1991, a sample of over 800 individuals was randomly selected representing all age groups. DMF-T and DMF-S scores were recorded, as well as percentages of caries free individuals. Results indicated that almost no fillings or crowns had been provided to the study population. The Missing 'M' component was low as was the Decay 'D' component, although this increased with increasing age, ranging from 0.33 D-T at the 0-12 age group to 2.46 at the 51+ age group. In the permanent dentition 88.4 per cent of those 0-12 years of age were caries free and 74.5 per cent were caries free in both the primary and permanent dentition. Almost 59 per cent of the 13-20 years olds were caries free and 32.8 per cent of those 21-50 years old. Only 16.7 per cent were caries free at age 51+ years old. The data indicate a relatively low prevalence of both coronal and root caries, and an effort has to be made to keep these figures low for years to come mainly by diet and dental health education.
Specific efforts need to be directed towards eliminating and/or minimising the significant barriers that threaten the oral health of nursing home and homebound individuals. Exciting new portable dental system options are now available which will help to overcome difficulties associated with meeting the dental needs of this cohort.

United States and Canadian studies have reported that a relatively large proportion of the institutionalized, older adult population is afflicted with a host of dental diseases and rarely seeks dental services. Analysis of existing published information indicates areas of concern including the need for incidence data, consensus on appropriate measures, and samples that will provide representative and comprehensive information about compromised older adults, irrespective of institutional or homebound status. Special emphasis should be placed on determining risk factors for dental disease, through longitudinal study of older adults.
The apparent association in the published literature of gender and age with dental fear and anxiety is far from consistent or universal. A random, age-stratified telephone survey of 398 adults was performed in a US metropolitan area: Denver, Colorado. Information collected included Kleinknecht's Dental Fear Survey (DFS). In addition to total DFS scores, values were also calculated for the sums of the five DFS physiologic response items (PATRESP) and 12 DFS fear-producing stimulus items (DENTSTIM). Tests for reliability of these three scales were performed (alpha = 0.804 to 0.936). In this sample population, significant age and gender differences were noted. In general, fear and anxiety decreased in importance with increased respondent age, with the largest difference noted between the 40-50 and 60-69 age groups. Increased fear and anxiety were most apparent among younger females (20-30 and 40-50) as compared with older females (60 and older). However, among males, the summary variable for physiologic response to fear and anxiety did not appear to be age-related. Among the oldest respondents (ages 70+), 12.2% did report a "major" response to muscle tension when in the dental chair. Females reported more fear of some stimuli associated with dental care (e.g., "feeling the drill in the mouth") than did males.
