This paper summarizes and evaluates epidemiologic evidence on adult dental conditions with a focus on older adults. Information is presented on coronal caries; root caries; loss of teeth, attrition, abrasion, and erosion; periodontal diseases; and oral cancer. The author concludes that the oral health status of the elderly in the United States is essentially unknown. There are no recent, representative population base studies of oral conditions in the elderly. Studies of prevalence or incidence of oral diseases typically include few elderly persons or describe a select group of elderly who are at high risk. Furthermore, it is not really known whether the incidence and prevalence of coronal caries or root caries is actually increasing or is part of a cohort effect. While oral cancers have been shown to increase with age, there is no information as to whether their incidence rates are increasing. While, clinically, there are indications that attrition, abrasion and erosion are characteristics that are more likely to be seen in older adults, there is no information about their distribution in the population. There is evidence that loss of teeth is decreasing but nothing is known about the patterning of that loss. As for periodontal diseases, much work is needed to identify various syndromes that may be distinguished by their distribution in the population as well as determining whether periodontitis is a condition responsible for a majority of tooth loss or just the majority of tooth loss in a small high risk group. In addition, some suggestions are presented for future directions of research in this area.  相似文献

Geriatric dentistry researchers are building a basic knowledge basic pertaining to the oral health status of older adults. Important findings on the prevalence of disease that run counter to “conventional wisdom” surrounding the oral health of older adults are that edentulism is decreasing, that both coronal and root caries are prevalent, that serious periodontal disease is not as prevalent as thought, that chronological age is not strongly associated with disease in older adults, and that oral lesions, especially those related to dentures, are prevalent. An important finding has been that the majority of disease seems to occur in a minority of the population. While the prevalence of oral diseases have been shown to be associated with water fluoridation, systemic diseases, use of medications, social and behavioral factors, and a variety of other oral conditions, there is only preliminary information on the incidence of disease and actual risk factors. The data available on the incidence of disease come from a study of community-dwelling older adults in Iowa, and these data generally confirm the prevalence results. Coronal and root caries are active in this older population with caries being the best predictor of tooth loss. Furthermore, most disease occurs in a high risk group. Multivariate models predicting people at highest risk for root and coronal caries implicate stress and anxiety, use of tobacco, and recent onset of illness as risk factors. In addition, preliminary results indicate that some dental conditions may be predictive of general health status.  相似文献

Abstract Objectives Numerous studies around the world have been conducted in order to understand the reasons for tooth extractions in various age groups. Most studies have dealt with the general adult population but little attention has been paid to the elderly population. In Israel, as in most of the western countries, the elderly population is growing rapidly and thus demands for its dental needs are also increasing. In order to meet the dental requirements of the geriatric population, data on the main reasons of tooth mortality have been collected. Design Retrospective analysis of reasons for extraction divided into three categories: caries, periodontal disease and “other’’. Subjects The files of 302 consecutive elderly patients aged 65-95 years attending for extraction. The cause for tooth extraction was gathered from the written diagnosis described by the operator as well as from radiographs. Setting Two surgical clinics in Jerusalem serving low income residents. Results Results indicated that 30% of the extractions were due to caries, 65% were due to periodontal disease and only 6.4% related to “other’’ reasons. In both, males and females, periodontal disease was the major cause for tooth loss yet, females exhibited more extractions due to caries than males (35%vs 23% respectively). A relatively high incidence of tooth loss was documented for the 85+ age group. Of the teeth that were extracted, incisors and molars were equally the most frequent (29%) followed by premolars (26%) and canines (17%). Premolars were the teeth most frequently extracted out of the teeth removed due to caries (32%) whereas incisors were the most frequently removed within the group of teeth extracted due to periodontal disease (31%). Conclusions The results of this study point to the importance of prevention and treatment of dental diseases, particularly periodontal disease, in adults aged 0 years and above in order to prevent tooth loss in their later years.  相似文献

Objectives: The Adelaide Dental Study of Nursing Homes was instigated to provide comprehensive information concerning oral disease experience, incidence and increments in a random sample of those older South Australians residing in Adelaide nursing homes. Methods: This paper presents caries experience results for existing and new nursing home residents, and caries incidence and increments for existing residents, from dental inspections conducted at the baseline and one‐year data collections. Results: The residents in this study were very functionally dependent, medically compromised, cognitively impaired and behaviourally difficult older adults, the great majority of whom had moderate to severe cognitive impairment. Residents gave their carers many complex and challenging behavioural problems during oral hygiene care provision. Existing and new residents had similar dental history, oral hygiene, and socio‐detnographic characteristics, and similar cognitive, medical, functional, and nutritional status. Oral disease experience was high in both existing and new residents. There were no significant differences between existing and new residents for their dentate status, tooth status, coronal caries experience, or root caries experience, with the exceptions that new residents had significantly greater mean number of teeth, more filled coronal and root surfaces, and also new residents had significantly fewer decayed retained roots. Large numbers of tooth surfaces were covered in plaque and debris that negated more precise assessment of caries. The existing residents had caries increments on both coronal (2.5 surfaces) and root surfaces (1.0 surfaces) over the one‐year period. Coronal caries incidence was 64% and root caries incidence was 49% of existing residents. Conclusions: Oral disease experience was high in both existing and new residents. There were few significant differences between existing and new residents’ oral health status. New residents were being admitted to nursing homes with a compromised oral health status. Coronal and root caries increments and incidence were high for existing residents over the one‐year period.  相似文献

Objectives: To determine the oral health status and treatment needs of elderly residents of a residential home in Ankara, Turkey. Background: Little is known about oral health problems of elderly living in the institutions. Methods: Among 216 elderly, 193 of them were interviewed and were clinically examined according to WHO criteria. Age, gender, educational and occupational status, oral hygiene practices, dental insurance, access to dental care and systemic diseases were recorded using a structured questionnaire. Coronal and root caries, periodontal disease, dental status and related treatment needs were assessed by two calibrated dentists. Results: The mean age of the subjects were 75.2 ± 8.3 in males, 79.1 ± 7.9 in females; 32.6% of subjects were dentate and the mean number of teeth was 3.7 ± 7.0 (median = 0). A functional dentition was present in 7.3% of subjects (≥20). The mean decayed, missing and filled teeth (DMFT) was 29.3 ± 5.8 (median = 32) and mean root caries was 2.2 ± 3.1 (median = 1.0). The major reason for tooth extraction was dental caries. Of the subjects, 20.7% had at least one untreated coronal caries and 18.1% root caries. The assessment of periodontal status according to CPI revealed that only four persons had nine healthy sextants with the score of ‘0’. Edentulousness was 67.4% while 11.9% of them lacked denture in both jaws. Conclusion: The results illustrated poor dental health and showed extremely high demand for the dental health services programmes for the elderly living in these institutions.  相似文献

Objective: The aim of this study was to describe the oral health status of older adults living in north‐eastern Germany. Materials and Methods: Representative samples of adults aged 60 years or older were examined as part of Study of the Health in Pomerania, a cross‐sectional, population‐based study. Data on 1446 subjects aged 60–79 years were evaluated for coronal caries using the decayed/missing/filled teeth (DMFT) index, root caries using the root caries index (RCI), calculus, plaque, bleeding on probing, pocket depth and attachment loss. Results: The prevalence of edentulousness varied from 16% in the 60–65‐year‐old group to 30% in the 75–79‐year‐old group, whereas the median number of remaining natural teeth per subject varied from 14 in the youngest age group (60–65 years) to one in the oldest (75–79 years). Among subjects aged 60–69 years, a quarter (26%) of the teeth examined had coronal restoration against 17% in the oldest age group (70–79 years). Coronal caries was found in 2% of the teeth in both age groups. Among teeth with gingival recession, 6% had fillings on root surfaces and 2% had root caries, irrespective of age. In all, 11% of the subjects had at least one untreated coronal lesion and 27% had at least one untreated root caries lesion. Plaque score, calculus score and bleeding on probing were higher in the oldest age group (70–79 years). The prevalence of periodontal disease expressed as the presence of at least one periodontal pocket of 4 mm and more, was higher in men and among the younger subjects (men aged 60–69 years: 85% vs. 71% in 70–79‐year‐old men; women aged 60–69 years: 71% vs. 62% in 70–79‐year‐olds). The prevalence of attachment loss of 3 mm or more followed a similar pattern. Conclusions: It seems therefore that in this population, the major oral health concern is related to caries and the small number of teeth retained among the dentate subjects.  相似文献

Objectives: To examine the reasons for tooth loss in an adult population. Methods: Patients who reported to the department of prosthodontics in Institute of Dental Sciences, Belgaum, located in the north‐western part of the state of Karnataka, in the southern region of India over a period of 2 months, with at least one missing tooth (excluding third molars) constituted the sample size. There were a total of 365 patients (185 females and 180 males) within the age group of 16–84 years (mean age 51.06 ± 16.47 years) who fulfilled this criterion. Socio‐demographic profile was recorded along with a clinical examination for assessing the number and pattern of tooth loss. The reasons for tooth loss were recorded according to the history reported by the patient. Results: In the present study of 365 patients, 58.9% of the patients were completely edentulous, 41% were partially dentate, of which 20.8% had lost their teeth from caries, 11% from periodontal disease and 9.3% from a combination of reasons. More females had lost their teeth because of dental caries whereas more males had lost their teeth because of periodontal disease, this being statistically significant. (χ2 = 16.53, p = 0.001). Highly significant results were obtained for age and reasons for tooth loss. (χ2 = 150.39, p < 0.001). Irrespective of the socio‐economic status, dental caries was the most common cause for tooth loss in partially dentate patients though it was not statistically significant (χ2 = 13.62, p = 0.325). Mandibular first molars were the teeth most frequently lost due to dental caries. The maxillary left central incisor was most frequently lost due to periodontal disease, followed by the maxillary right central incisor. Conclusions: Since both dental caries and periodontal disease contributed to tooth loss at different ages, risk indicators need to be identified.  相似文献

Objectives: This study reports findings on the dental status and the prevalence of dental caries among a group of 85‐year‐old Danes from the Glostrup 1914 Cohort, Denmark. The purpose of the study was to analyse whether caries experience was related to number of teeth and to indicators of functional ability and cognitive function. Methods: A total of 191 individuals (78 men and 113 women) participated in a cross‐sectional population study conducted in 2000. Using mobile dental equipment, a clinical oral examination and an interview were administered to all participants in their homes. Functional ability was measured by the Mob‐H scale and cognitive function was assessed by the Mini‐Mental State Examination. Results: Fifty‐nine per cent of the participants had their own natural teeth and for the dentate participants, the mean number of teeth was 13 (range 1–27). A high prevalence of active caries on coronal and root surfaces was observed. Older adults with few natural teeth had a higher prevalence of active coronal and root caries and a higher unmet treatment need than older adults with many teeth. Further, the study showed that 85‐year‐old persons with reduced functional ability and cognitive impairment tended to have more active caries than 85‐year‐olds with no impairment. Conclusions: A substantial proportion of 85‐year‐old individuals had retained a natural dentition; however, active dental caries is a problem of concern among the most elderly.  相似文献

Oral disease experience of older adults seeking oral health services Objective: The objective of this investigation was to describe the dental disease (dental caries and alveolar bone loss) experience in a sample of community‐dwelling older adults who regularly utilize dental services in New York City. Background: Public financing for dental care directed at older adults in the United States is minimal. Improved preventive methods, primarily the use of fluorides, have resulted in declines in tooth loss, and concomitant increase in risk for dental diseases among older adults. While the oral disease burden in institutionalized elderly and those unable to access services is well‐documented, the dental care needs of older adults who access dental services are not well documented. Materials and Methods: Radiographic and record review were used to determine prevalence of dental caries, alveolar bone loss, frequency of service utilization, and medical status in this cross‐sectional investigation of a sample of older adults (N = 200) using dental services at Columbia University College of Dental Medicine. Results: Only 9% of the sample was completely edentulous, the mean DMFT was 19.9 and mean alveolar bone loss was 3.6 mm. Missing and Decayed Teeth accounted for 57.8% and 6.5% of the total caries burden respectively. Missing Teeth and alveolar bone loss increased with increasing age, but there was no increase in Decayed Teeth. Conclusions: While access to and utilization of dental services may result in improved tooth retention, older adults who use dental services continue to have dental care needs, especially periodontal care needs.  相似文献

Dental health was evaluated in two populations of raccoons (Procyon lotor) in western Illinois (USA); one was from a rural agricultural area with low human density and the other from a nearby state park heavily used by humans and raccoons. From 1989 through 1993, 300 raccoons were live-trapped in the agricultural area and 246 raccoons were live-trapped in the park. Oral health was assessed using gingival and calculi indices and by measuring loss of attachment and tooth wear. Raccoons from the park were significantly older and smaller, but not thinner, than raccoons from the farmed area. Gingival and periodontal indices, tooth wear, tooth loss, and caries increased significantly from juveniles to yearlings to adults, at both sites. Males had higher levels of gingivitis and loss of periodontal attachment than females, but were similar on other dental measures. There were no seasonal differences between raccoons in dental indices. Animals with high scores for one oral measure tended to have high values for all indices. Dental health was generally good for juveniles and yearlings from both sites. Among adults, periodontal indices and the prevalence of caries were significantly higher in the park, but prevalence of broken or missing teeth was similar for both populations. There was no association between body condition, and a higher dental score or more missing or broken teeth.  相似文献

Objectives: To quantify the adverse effects of the number of xerostomic medications on dental caries, oral mucosa, andperiodontal disease. Design: Secondary analysis of across‐sectional study of the Veterans Dental Study. Setting: Four New England area VA outpatient clinics. Subjects: The sample consists of 345 male veterans participating in The Veteran's Dental Study who also had pharmacy records. Main outcome measures: Oral health data included total surfaces of coronal caries, a modification of the root caries index, mean oral mucosa scores, and Community Periodontal Index of Treatment Need (CPITN). Oral health parameters were measured and recorded in clinical dental examinations. Exposures: Intake of xerostomic medications 14‐385 days prior to the dental examination. Statistical Analyses: The relationships between exposure and outcome were analyzed via linear and logistic regression methods adjusting for possible confounding factors such as disease burden index, alcohol consumption, dental care, and smoking status. Results: Veterans who were taking at least one xerostomic medication were almost three times more likely to have mean mucosa scores in the worst 25 percentile than veterans taking no xerostomic medications, OR= 2.63 (confidence interval [CI] 1.34,5.16, p=0.03) after adjusting for age, number of teeth, disease burden index, income, smoking and alcohol use. Participants who were taking at least one xerostomic medication experienced higher but non‐significant increases in coronal (OR =1.21; CI. 0.66, 2.25) and root caries (OR =1.10 CI. 0.54, 2.24) measured by numbers of total decayed surfaces. Conclusion: There were significant deleterious effects of xerostomic medications on oral mucosa. However, xerostomic medications do not appear to increase coronal caries, or periodontal index measured by CPITN among ambulatory, community dwelling participants who were able to perform routine preventive oral care.  相似文献

The survey aimed to determine the reasons for extraction of permanent teeth by general dental practitioners in urban and rural population of the Senj region, Adriatic coast, Croatia. During a two-year period (1998-9), a total of 2006 teeth were extracted in both regions, in patients aged 15+. The causes were defined as follows: (1) decay or root without a crown (radix relicta), (2) periodontal disease, (3) endodontic or periapical diseases and (4) other reasons--orthodontics/prosthodontics and dental trauma. The statistical Chi-square-test was used to determine the significant difference between the populations and the sexes. Dental caries was the most frequent cause for extraction (over 50%), followed by endodontic and periapical diseases (23%) as the result of untreated caries and at the end periodontal disease (21%). Urban population more often lose teeth due to periodontal disease (22.75%) than rural (18.93%, p < 0.05). Similarly, this is more frequent in the urban male population (25.61%) than the female urban population (20%, p < 0.05). In rural areas, people more often lost teeth as a result of endodontic and periapical disease (25.85%) than in the urban locations (19.07%, p < 0.01) and this is more frequent in women from rural areas (28.37%) than the rural men (22.44%, p < 0.05). Periodontal disease was not the main cause of tooth loss in either the rural or the urban population. Dental caries and its sequel remain the most important challenge for the dental service. It also reveals the inadequacy of dental services. Education of both the population and the general dental practitioners must be conducted in order to improve oral hygiene and to insist on conservative rather than extraction therapy.  相似文献

The dental remains of ten adult chimpanzees from Gombe National Park, Tanzania, were examined for enamel attrition, caries, abscesses, periodontal disease, and tooth loss. Age was the underlying factor in the development of dental pathology, in that enamel wear was present to some extent in all ten but was uniformly severe only in the three for whom estimated age at death was 39-43 years. In turn, enamel wear appears to have been the direct cause of abscess development, periodontal disease, and tooth loss. Periodontal disease was commonly expressed as alveolar resorption, particularly around the premolars and molars. This involvement was variable in all except the two youngest. Some interesting wear patterns were evident in the form of deep grooves in the upper incisors and dramatic notching of the lower canines. These patterns, and enamel attrition in general, were attributed to normal mastication and to various stripping activities. Only one carious lesion was observed, in a male with an estimated age of 26 years. An accurate assessment of the actual prevalence of caries was obscured by enamel wear and tooth loss in the older individuals.  相似文献

In a national survey of adult dental health conducted in the Republic of Ireland in 1989/90 a total of 1,527 subjects aged 25 and older were examined for root surface caries. It was found that the prevalence of root surface caries was highest in older age groups and also amongst males, residents of non-fluoridated communities and those earning low incomes. Tooth loss masked the potential prevalence of root surface caries. With more persons retaining their natural teeth into middle and old age the prevalence of root surface caries is likely to increase in the future.  相似文献

Objectives: The Oral Health of Older Adults with Dementia was instigated in the late 1990s to quantify and compare coronal and root caries incidence and increments in community‐living older Australians with and without dementia. Methods: A longitudinal design was used to conduct dental inspections at baseline and one‐year, for two groups of randomly selected community‐living older adults ‐ one group of 116 people with dementia and a comparison group of 116 people without dementia. Results: At one‐year there were 103 dementia and 113(112 dentate) non‐dementia participants. Coronal and root surface caries incidence was higher for dementia participants (p<0.05). Dementia participants had higher coronal and root caries adjusted caries increments (ADJCI) (p<0.01). Both coronal and root ADJCI were evident in half of dementia participants, compared with one‐quarter of non‐dementia participants. Dementia participants with higher coronal ADJCI were those who had visited the dentist since baseline, who were taking neuroleptics with high anticholinergic adverse effects, and whose carer had high carer burden score (p<0.01). Dementia participants with higher root ADJCI were those needing assistance with oral hygiene care and whose carers had difficulties with oral hygiene care (p<0.05). Baseline characteristics predictive in linear regression for: (1) coronal caries increments among all participants were ‐ dementia participants, those with cognitive testing scores indicative of moderate‐severe dementia, those with private health insurance; (2) root caries increments among all participants were ‐ dementia participants, and those who had 1 decayed/filled root surface at baseline. Among dementia participants, being male was the baseline characteristic predictive in logistic regression for coronal caries increments, and having 1 decayed coronal surface was the baseline characteristic predictive for root caries increments. Conclusions: Coronal and root caries incidence and increments were significantly higher in the community‐living older adults with dementia over the one‐year follow‐up period. Dementia participants had high levels of coronal and root caries increments; characteristics related to high caries increments included sex (males), dementia severity (moderate‐severe), high carer burden, oral hygiene care difficulties, use of neuroleptic medication (with high anticholinergic adverse effects) and previous experience of caries.  相似文献

Observations of dental diseases among prehistoric populations of Hungary   总被引:1,自引:0,他引:1  
The incidence of dental disease among people in developing countries today raises questions about the variation in the oral health of prehistoric populations. Considering these questions, we offer observations describing several types of dental disease which occurred among certain prehistoric populations of Hungary. The dental remains of 162 individuals recovered from seven sites of the Neolithic, Copper, and Bronze Age periods were examined for evidence of caries, hypoplasia, and periodontal disease. Appropriate methods were used to describe and record these dental lesions. The incidence of dental caries was low by comparison to other prehistoric agriculturists except for two forms of root caries: cervical and cemental. These types accounted for 68% of all the carious teeth recorded. Enamel hypoplasia was also lower than expected, occurring on only 4% of the total number of teeth. Periodontal abscesses were rare but other milder forms of periodontal lesions were frequent. Alveolar bone resorption occurred in varying degrees and followed the expected age distribution. The few exceptions were children or adolescents whose crania had other lesions suggesting a mineral metabolic disturbance. The lower incidence of enamel caries is likely due to high fluoride ingestion which also may have influenced the expression of enamel hypoplasia. No clear population trends were seen in dental disease incidence except for cemental caries which were found among Copper and Bronze Age remains.  相似文献

Over a dozen studies have been conducted on the prevalence of and factors associated with root caries, yet our knowledge of this disease process remains limited. This is due, in large part, to a lack of consistency of reporting among the studies undertaken and the wide spectrum of population groups investigated. Nevertheless, the occurrence of root caries is between 20 and 40 percent in healthy, urban adults. Certain population groups such as the institutionalized elderly and patients with periodontal disease tend to exhibit much larger prevalence rates. New root caries develops slowly and tends to be concentrated in a few individuals, usually on the buccal and proximal surfaces of teeth. It is generally accepted that only roots with gingival recession are susceptible to root caries and that age, sex, oral hygiene, diet, saliva, systemic fluoride and previous carious experience have been shown to be associated factors. The next wave of investigations of root canes should focus on testing hypotheses relating to causation so that efficacious preventive and treatment procedures can be developed.  相似文献

Indicators for root caries in Danish persons with recently diagnosed Alzheimer’s disease Objective: To identify indicators of root caries among persons with newly diagnosed Alzheimer’s disease (AD). Background: Few studies have investigated dental caries in older adults with AD. Previously we found that persons with AD had significantly more root caries compared to persons with dementia other than AD. Methods: Participants were recruited from two university hospital clinics in Copenhagen, Denmark. A team of neurologists/geriatricians carried out the diagnostic screening. The study included an interview, oral examination and medical records. Results: We evaluated potential indicators of root decay across subjects with 3+ decayed surfaces vs. <3 decayed surfaces. Variables associated with increased odds of root caries were age over 80 years, 2+ decayed coronal surfaces and 5+ filled root surfaces. Among the social variables, living with someone was associated with a nearly 70% reduction in the odds of having 3+ surfaces of untreated caries. Discussion: Root caries is highly prevalent among individuals with new AD and there is still a strong need for active assessment of and attention to oral problems in persons with AD. Our findings document that recently diagnosed AD cases with multiple coronal caries lesions are at elevated risk of having more root caries. Also persons 81+ years and those with multiple root fillings are more likely to have numerous untreated root lesions.  相似文献
