摘要:

The population of the world is changing and the science dealing with the study of these changes in human populations, in terms of disease, health and mortality has been called demography. It can be understood to include the evaluation of the size, density, and distribution of populations including the influence of a variety of factors such as age and economics. This paper will review the distribution of the world's population with regard to age and utilization of dental care with particular emphasis on the older cohorts.

摘要:

It has been assumed that improved oral health leads to a better quality of life for elderly people. It is, however, difficult to assess the benefit of oral health care, especially dental treatment in terms of life quality. The normative assessment, based solely on clinical diagnosis, often leads to an overestimation of the true need for treatment, especially among the ‘frail elderly’, some of whom do not want treatment, either because there is no perceived need or expressed demand. Others are very ill, and some in such a poor mental condition that they can not express any demand for treatment, and would probably not benefit from treatment e.g. new dentures. The realistic treatment need is an attempt to assess the true need for treatment in relation to the benefit provided. It is a combination of the normative need, the self‐perceived need, and the expressed demand for treatment, and takes into account the mental and physical state of the individual, as well as ethical considera

摘要:

The effects of ageing and dental state on the cross‐sectional area and density of two jaw muscles, the masseter and medial pterygoid, were investigated using computed tomography. The study involved 84 male and 70 female subjects between the ages of 20 and 90 years. The cross‐sectional area of both muscles showed a significant reduction with age; values for female subjects being found in the lower range of the distribution. When consideration was given to the presence or absence of a natural dentition, the cross‐sectional area of both muscles in edentulous subjects showed a greater decease throughout the age range studied. There was a significant decrease in the density of the muscles with increasing age. Previously, this has been interpreted to indicate a progressive increase in fat and fibrous tissue. Subject gender and the absence of teeth appeared to have little effect on this parameter. Changes in the cross‐sectional area and density of these muscles would appear to be consistent with a general age related change of muscle tissue in the body as a whole and may specifically indicate a reduction in the masticatory forces which can be or are being utilised by ageing patients, many of whom have no remaining natural de

摘要:

The assessment of a patient's capability to adapt to new dentures is still a challenge in the prosthetic treatment of geriatric patients. The aim of this study was to assess the relationship of age to manual motor ability as well as the mental concentration capacity in comparison to the oral motor ability and the capability to adapt to new dentures. Sixty complete denture wearers volunteered for the experiment. The results indicate, that the manual motor ability and the mental concentration capacity deteriorate with age, whereas the relationship of age to adaptation to new dentures and oral motor ability is less obvious. This may be due o t the patient's denture experience.

摘要:

The predicament of being both elderly and edentulous undermines life quality for both patient and dentist. The former suffer because of morphological and functional compromises, the latter because of a dearth of safe and predictably successful clinical techniques. The introduction of the osseointegration technique suggested great promise for profoundly changing this predicament, but the specific merits of this approach have been mainly extrapolated ones. The purpose of this study was to examine the clinical success of treatment with osseointegration for patients who were 65 or older at the time of implant insertion. A second group of patients, who became 65 during the course of the study was also studied and the results recorded separately. Data regarding the longevity of implants and prosthodontic restorations and the numbers and types of problems encountered were recorded. The evidence suggests that the biological anchorage of tooth root analogues in elderly jaws is predicatbly successful and enhances the quality of life for geriatric patients who are edentulous.

摘要:

The possible relationship between patient age and the long term survival of fixed prostheses was studied in a randomised group of persons, who had received restorative treatment by general practitioners 13 years prior to this study. These fixed partial dentures had a mean extension of 6.9 units and a mean pontic/abutment ratio of 0.47. The group studied consisted of 77 persons who agreed to participate from an original group of 150 persons. Of the original group 20 had died, 17 were not traceable or unable to participate for medical reasons, and 36 declined to participate. The outcome of the treatment was compared between the following age subgroups (age as at the time of the original treatment) by division of the data at 37, 60 and 65 years. In these subgroups between 20 and 50 per cent of the prostheses had been lost or partially lost during the fifteen year period. Most of the failures and unacceptable quality ratings were found to be caused by fractures, loss of retention and/or dental caries. However, no systematic differences were found between any of the age subgroups studied.

摘要:

This study covers the characteristics of reduced dentitions in a population of elderly people. The sample consisted of 329 independently living individuals between 55 and 75 years of age. They all had one or more natural teeth and were all interviewed and investigated clinically. The findings showed that 13%of the subjects had a natural dentition with at least the first molars: 4–7 natural occlusal units (defined as ‘pairs of opposing teeth that support the occlusion’) occurred in 37% of the subjects; 1–4 natural occlusal units in 41% and 0 units in 9% (only anterior contacts). A removable partial denture was worn by 39% of the subjects: most of them were acrylic based dentures (61%). The percentages of restored teeth per subject were high. The need for further restorations, however, was low. Periodontal problems were uncommon: 25% of the subjects had one pocket above 5 mm: 8% had severe problems. Poor oral hygiene was present in a quarter of the cases. Most of the subjects (70%) had no pain or noises in the temporomandibular joint. Only 10% of subjects had more than one sign of craniomandibular dysfunction. Most of the subjects (85%) visit their dentist regularly and 65% had their last tooth extraction more then three years ago. A majority mentioned that they have never had problems with their dentition in the past: 50% had had no real toothache for the last five years. However problems with food‐packing were often mentioned. It can be concluded that, although the dentitions of the elderly in this population are often reduced, their dentitions are in general in good condition and few give TMJ

摘要:

The medical and dental status, and drug utilisation pattern of Canadian Inuit elders (60+years) were evaluated. Inuit elders averaged 6.3 medical conditions per person, primarily nervous system‐sense organ deficits, respiratory problems and systemic infections. The mean number of drugs being used was 2.5 per person, primarily analgesics, bronchodilators and antibiotics. Poorly fitting dentures, and high levels of tooth decay, periodontal disease, soft tissue and TMJ anomalies were documented. Compared to older southern Canadians, the medical and dental findings for these Inuit elders were different. Drug utilisation rates were consistent with older southern Canadians, but different drugs were take
