A study of occlusion in elderly Japanese over 80 years with at least 20 teeth

Objectives: The purpose of this study was to identify the occlusal status of elderly Japanese over 80 years with at least 20 teeth. Materials and methods: The study enrolled 76 elderly Japanese (44 male, 32 female) with a mean age of 82 years and an average of 25.7 remaining teeth. The study consisted of intra‐oral examination, intra‐oral and facial photographs, radiographs and impressions for study casts. Results: No gender difference was observed in age or number of remaining teeth. Anteroposterior occlusal relationship was characterised by maxillary protrusion in 67.6%, acceptable overjet in 31.0%, and anterior crossbite in 1.4%. Vertically, deep bite was noted in 33.8%, acceptable overbite in 64.8%, and open bite in 1.4%. Most of the subjects had either Angle class I (68.4%) or class II (25.7%) canine relationship. Only 3.9% of the subjects had upper anterior crowding. Lower anterior crowding was observed in 23.7%, but tended not to be severe. Conclusion: These results indicate that Japanese who attained the goal of ‘8020’ have a relatively good occlusion.

The association between renal function and tooth loss in Japanese community‐dwelling postmenopausal women Objectives: This study examined whether low renal function is associated with the number of remaining teeth among community‐dwelling elderly Japanese. Background data: Many elderly individuals display both low renal function and tooth loss. Materials and Methods: Subjects comprised 405 randomly selected women (55–74 years old). Serum cystatin C level was used to assess renal dysfunction. Multiple linear regression analysis was used to evaluate the relationship between number of remaining teeth and serum cystatin C level, with number of remaining teeth as the dependent variable. Six variables were selected as independent variables in the final model: serum cystatin C; age; mean clinical attachment level; serum cross‐linked N‐telopeptide of type I collagen level; body mass index and smoking habits. Results: Multiple linear regression analysis revealed a significant relationship between number of remaining teeth and serum cystatin C level. The beta value for serum cystatin C level for the number of remaining teeth was ?0.11 (p = 0.018). Conclusion: This study indicates a relationship between serum cystatin C level and number of remaining teeth, suggesting that low renal function could be associated with tooth loss.     

Cephalometric study of elderly with nearly intact dental arches

Objective: The purpose of this study was to investigate the craniofacial morphology of elderly people with many remaining teeth using cephalometric analysis. Subjects and methods: The subjects were 30 Japanese elderly who participated in the ‘8020 campaign 2001’ in Bunkyo Ward, Tokyo, organised by The Dental Association of Tokyo, as well as 30 Japanese young adults with normal occlusion. Lateral cephalograms of all subjects were analysed using the Coben method. Results: In the female elderly group, the lower face depth was smaller than in the younger adults. In the male elderly group, the height and depth of both the total face and the lower face were longer than in the younger group. In comparing the 8020 achievers with the younger group, the proportion of the lower facial height was greater than the upper facial height, and this finding was more pronounced in women than in men. Conclusion: For the lateral facial pattern of the elderly, a reduction of lower facial height because of tooth occlusal reduction was not apparent. It was clear that there are age differences for males and females; in addition, differences in the total face and lower face area of the elderly group were due to their having many remaining teeth over a long time period. Also, these changes were more apparent in women than in men, and it is clear that there is a male–female difference in ageing.     

'Inadequate' dietary habits and mastication in elderly men

Objective: The aim of this study was to re‐evaluate data about oral status, mastication and nutrition in elderly men in Malmö, Sweden, recorded in 1985–1987, to assess associations between inadequate dietary habits, oral conditions and masticatory function. Materials and methods: Four hundred and eighty‐one men, aged 67–68, participated in a comprehensive health examination, including tooth and denture status and masticatory tests. A separate study of dietary habits and nutritional status was made. Ninety‐five men had inadequate dietary habits. The databases of dental/denture status, mastication, nutritional status and social network factors were re‐evaluated for assessment of associations. Results: No significant differences between those with adequate or inadequate nutrition were found with regard to the number of teeth, occlusal contacts or removable dentures. Also self‐assessed chewing did not show any differences. Conclusion: Inadequate dietary habits were independent of teeth and denture status. Some correlations to social network conditions could be identified. Overweight, obesity, low physical activity and high alcohol intake were more common among those with inadequate nutritional intake.     

Relationship between survival rates and numbers of natural teeth in an elderly Japanese population

Objectives: The objective of this study was to assess whether elderly people with 20 or more natural teeth were more likely to live longer than a cohort with less than 20 teeth. Materials and methods: Groups of elderly people over 80 years of age (24 males and 35 females) with 20 or more teeth (≥20 group) were compared with elderly people (24 males and 35 females) with less than 20 teeth (<20 group). Follow‐up studies were conducted at regular intervals for 10 years from July 1992 to July 2002. The cumulative survival rate of the ≥20 group (average ± SE tooth number of teeth – males, 23.9 ± 0.6; females, 23.8 ± 0.4) was compared with the <20 group (average number of teeth – males, 3.8 ± 1.1; females, 2.6 ± 0.8). The multivariate Cox proportional hazard models with the number of teeth in a group (≥20 group or <20 group). Smoking status and alcohol intake as covariates were used to adjust the cumulative survival rate. Results: The male participants in the ≥20 group had a significantly higher cumulative survival rates (p < 0.05) than the <20 group at 18 and 21 months from baseline. There were no significant differences in survival rates between the female groups. Adjusted cumulative survival rate was significantly different at 72, 75 and 78 months between the ≥20 group and <20 group for males but not for females. Conclusion: Having 20 or more natural teeth was associated with increased survival rate in elderly males, but not among the elderly females.     

Tooth loss and associated factors in long-term institutionalised elderly patients

Objective: To compare partial and total tooth loss in dependent institutionalised elderly patients and identify any associated factors. Background: A poor oral health status, together with a reduction of autonomy can seriously affect the general health and increase the risk of death in elderly people. Those with total tooth loss and in need of assistance are the most at risk. Materials and methods: In 2004, a cross‐sectional study of 321 elderly patients was conducted in long‐term hospital services provided in Montpellier, France. Socio‐demographic, behavioural, medical and oral health information was recorded for each patient. Multivariate logistic regression models were performed to test the relationship between those covariates and partial or total tooth loss. Pearson chi‐squared tests were used for bivariate analyses. Results: The proportion of edentulousness was 26.9%; among these12.6% had no dentures. The factors significantly associated with edentulism were: an age ‘older than 87 years’ [odds ratio (OR) = 9.4], the presence of a nephropathy (OR = 6.8), and inadequate oral hygiene (OR = 0.1). The factors most significantly associated with partial tooth loss (at least 21 missing teeth) were ‘cancerous disease’ (OR = 9.9), the presence of a nephropathy (OR = 5.6) and the presence of a neurological disease (OR = 4.1). The factors significantly related to dentate status (20 or more natural teeth retained) were ‘hypertension treatment’ (OR = 2.4), and ‘cortisone treatment’ (OR = 0.2). Conclusion: General health problems as well as a poor oral condition were significant risk indicators for tooth loss among the long‐term institutionalised elderly. This suggests that the number of remaining teeth has a strong effect on oral health‐related quality of life.     

Oral health among institutionalised elderly in Zagreb, Croatia

Objective: A survey of dental health status was conducted in the institutionalised elderly in Zagreb, Croatia in order to assess the dental and oral health of the elderly population. Participants: In 139 institutionalised elderly from a single nursing home in Zagreb, dental and oral status was registered according to World Health Organization criteria. There were 108 (77.7%) female and 31 (22.3%) male subjects aged 58–99 years. Results: The results showed that 45.3% of the interviewed persons were totally edentulous in both jaws. A significant increase in prevalence of edentulousness with the increasing age was recorded. The mean decayed, missing and filled teeth number was 27. The average number of teeth with caries was 1.03 per person, the number of the teeth extracted was 6.9 per person and teeth with fillings 0.74 per person. The average number of teeth with root caries was 0.17. Approximately 9 teeth per person were in need of treatment. Filled teeth were found 25.9% of subjects and decayed teeth in 30.9%. The mean number of remaining sound teeth, decayed teeth and residual roots in the elderly decreased with increasing age. Complete periodontal treatment was required in 5.8% of the participants and no significant differences between genders in periodontal status could be noticed. Conclusion: The results of this study suggest poor dental health in this group of the institutionalised elderly and the necessity of improving and implementing some special features in the dental health services programs for the institutionalised elderly.     

Relationship between oral health, nutrient intake and nutritional status in a sample of Brazilian elderly people

Objective: To evaluate the relationship between the oral health condition, the nutrient intake and the body mass index (BMI) in elderly people. Background: Impaired dentition has been associated with an inadequate consumption of key nutrients and with changes in nutritional status in elderly people. Materials and methods: The sample comprised 887 elderly people, aged 60 and over, of whom 816 underwent a clinical oral examination and were allocated into groups according to the numbers of teeth and number of posterior occluding pairs of natural teeth. Nutritional status was determined using the BMI. Dietary intake was assessed by a 24‐h diet recall interview and the data from these records were converted to nutritional intake using Diet Pro software. Differences between means were evaluated using anova , together with the Tukey test or Dunnet test, according to the normality of the data. Associations between categorical variables were tested using chi‐square analysis. Results: Ages ranged from 60 to 96 years (mean, 71.46 years), with 47% of the respondents in the 60‐to 69‐year‐old group. A high DMFT index (mean, 27.81) was observed with the missing component accounting for 88.8% of the index. Significant differences were observed between the mean intake of nutrients and the number of posterior occluding pairs of natural teeth (p < 0.05). No significant differences were found between the number of teeth and BMI. Conclusion: Nutrient intake is associated with the oral health status as defined by clinical measures.     

Oral status and its association with obesity in Southern Brazilian older people

Background and objective: The loss of a functional dentition imposes eating difficulties and food avoidance, which may be detrimental in terms of nutritional status and health. The objective of this study was to investigate whether tooth loss and edentulism that were not rehabilitated with dental prostheses were associated with obesity among elderly in Southern Brazil. Materials and methods: A random sample of 872 independently living elderly was evaluated by means of a cross‐sectional study. Socio‐demographic, medical history and behaviour data were assessed using a standardised questionnaire. Two trained dentists assessed the number of teeth and use of prostheses in accordance with the WHO criteria. Height and weight were assessed and used to generate body mass index (BMI = weight (kilos)/height (cm)²) data. Participants were categorised into non‐obese (BMI ≤ 30) or obese (BMI > 30). Multivariate logistic regression was used to model the relationship between number of teeth and use of dental prostheses with obesity adjusting for confounders. Results: Multivariate logistic regression revealed that edentulous persons wearing only upper dentures (OR = 2.34, 95% CI 1.18–4.27) and dentate participants with one to eight teeth wearing 0‐to‐1 prosthesis (OR = 2.96, 95% CI 1.68–5.19) were more likely to be obese. Conclusion: The results show that a poorer oral status, represented by having fewer teeth that were not replaced by dental prostheses, was associated with obesity in Southern Brazil older people, suggesting a close relationship between poor oral status and systemic conditions that may have important clinical implications.     

Nutritional status and oral status of the elderly with dementia: a 2-year study

doi: 10.1111/j.1741‐2358.2011.00555.x Nutritional status and oral status of the elderly with dementia: a 2‐year study Objectives: To determine the relationship between denture wearing and nutritional status in the elderly with dementia. Background: There could be a correlation between nutrition, oral health, dietary habits, patients’ satisfaction, and their socio‐economic status in the elderly, and the relationship between compromised oral status and nutritional status in the elderly with dementia. Subjects and methods: A 2‐year follow‐up study of 63 elderly Japanese women with and without dentures from a nursing home was undertaken to investigate their oral, physical and mental, and nutritional status. Results: Each item for 2006 and 2008 in this study showed no significant difference between 2006 and 2008, except the calories/day. The elderly with dementia without complete dentures during the 2 years of the study only significantly decreased the mean of the calories/day. Conclusion: The calories/day of the elderly with dementia without dentures decreased after 2 years. Denture wearing for the elderly with dementia could be necessary to maintain a satisfactory intake of calories.     

Masticatory ability in 80-year-old subjects and its relation to intake of energy,nutrients and food items

Objective: The aim of the present study was to analyse the relationship between masticatory ability (self‐assessed masticatory ability and bite force) and intake of energy, nutrients and food items in a population sample of elderly subjects. Design and Subjects: From a population sample of 80‐year‐old people, 160 individuals (74 men and 86 women) took part in an odontological study. Main Outcome Measures: A dental examination including bite force recording, a questionnaire focusing on self‐assessed masticatory ability, and a dietary interview. Setting: Department of Geriatric Medicine, Göteborg University, Sweden. Results: The dental status among the participants varied much (from edentulous in both jaws ‐ 22% ‐ to more than 20 natural teeth ‐ 30%). The mean maximum bite force was higher in men (165 N) than in women (105 N). Bite force was significantly correlated to the Eichner index and to the number of teeth. One third of the subjects reported no masticatory problem, whereas 18% identified 3 such problems. The intake of energy and nutrients varied much but the means were well above recommended values. The correlations between dental status and bite force on one side and dietary intake on the other side were in general weak and most often statistically non‐significant. Impaired general health and reduced dentition were both associated with more masticatory problems. Conclusion: The examined sample of 80‐year‐old subjects had a great variation in dental status, bite force and self‐assessed masticatory ability, but these factors had only a minor influence on dietary selection and intake, which on average were well above recommended values.     

The relationship between seven health practices and oral health status in community‐dwelling elderly Thai

Gerodontology 2012; doi: 10.1111/j.1741‐2358.2012.00672.x The relationship between seven health practices and oral health status in community‐dwelling elderly Thai Objective: This study aims to analyse the relationship between seven health practices, oral health behaviors, and oral health status in community dwelling elderly Thai. Materials and methods: The subjects were 612 elderly people (mean age = 68.8 ± 5.9 years). Questionnaires survey about sociodemographics, self‐reported seven health practices and oral health behaviors were conducted by trained interviewers. Oral examinations investigated the number of teeth present, decayed teeth, periodontal status and functional tooth units (FTUs). Oral malodor was assessed by Organoleptic Test, and unstimulated saliva was collected for 5 min. Results: Five health practices (smoking, drinking, physical activity, breakfast and weight maintenance) were significantly related with oral health behaviors. ancova analysis demonstrated the following significant associations: (i) smoking behavior with number of teeth present, number of FTUs, decayed teeth, periodontal disease, oral malodor and salivary flow rate, (ii) drinking alcohol behavior with number of teeth present, number of FTUs, periodontal disease, oral malodor and salivary flow rate, (iii) eating breakfast behavior with periodontal disease, oral malodor and salivary flow rate, (iv) eating between‐meal snack with number of teeth present, number of FTUs, decayed teeth and periodontal disease, (v) maintaining weight with number of teeth present, number of FTUs, periodontal disease and oral malodor, (vi) sleeping with number of teeth present, number of FTUs, periodontal disease, oral malodor and salivary flow rate, (vii) physical activity with periodontal disease and salivary flow rate. Conclusion: Good health practices were related with good oral health behaviors. Moreover, general health practices were associated with the clinical oral health status such as number of teeth present, decayed teeth, FTUs, periodontal disease, oral malodor and salivary flow rate. The elderly with good general health practices were considered to have good oral health status. Improving general health habits are suggested to lead to better oral health for the elderly, and vice versa.     

BMI and All‐cause Mortality Among Japanese Older Adults: Findings From the Japan Collaborative Cohort Study

The association between BMI and all‐cause mortality may vary with gender, age, and ethnic groups. However, few prospective cohort studies have reported the relationship in older Asian populations. We evaluated the association between BMI and all‐cause mortality in a cohort comprised 26,747 Japanese subjects aged 65–79 years at baseline (1988–1990). The study participants were followed for an average of 11.2 years. Proportional‐hazards regression models were used to estimate mortality hazard ratios (HRs) and 95% confidence intervals. Until 2003, 9,256 deaths occurred. The underweight group was associated with a statistically higher risk of all‐cause mortality compared with the mid‐normal‐range group (BMI: 20.0–22.9); resulting in a 1.78‐fold (95% confidence interval: 1.45–2.20) and 2.55‐fold (2.13–3.05) increase in mortality risk among severest thin men and women (BMI: <16.0), respectively. Even within the normal‐range group, the lower normal‐range group (BMI: 18.5–19.9) showed a statistically elevated risk. In contrast, being neither overweight (BMI: 25.0–29.9) nor obese (BMI: ≥30.0) elevated the risk among men; however among women, HR was slightly elevated in the obese group but not in the overweight group compared with the mid‐normal‐range group. Among Japanese older adults, a low BMI was associated with increased risk of all‐cause mortality, even among those with a lower normal BMI range. The wide range of BMI between 20.0 and 29.9 in both older men and women showed the lowest all‐cause mortality risk.     

Direct restorative treatment of anterior weared teeth after re‐establishment of occlusal vertical dimension: a case report

doi: 10.1111/j.1741‐2358.2012.00630.x Direct restorative treatment of anterior weared teeth after re‐establishment of occlusal vertical dimension: a case report Objective: The loss of posterior teeth resulting in a lack of stability may lead to excessive mandibular load on some points of occlusion of the remaining teeth, causing wear. The rehabilitation of these cases must be carefully planned and the treatment requires a period of adaptation with a new vertical dimension. Background: This case report describes the treatment of a patient with a loss of almost all posterior inferior teeth and a consequential loss of occlusal vertical dimension and accentuated wear of anterior elements. Materials and methods: Provisional removable partial dentures were manufactured and the patient used them for a period of adaptation prior to restoration of the anterior teeth. After the patient’s adaptation with the new occlusal dimension, anterior restorations were made using a mycrohibrid resin composite with different color aspects for an optimal stratification. Results: The restorations achieved an aesthetic configuration with ideal function as the final result and the occlusion showed a satisfactory stability for a provisional removable partial dentures. Conclusion: This article presents an anterior direct rehabilitation approach not only as an alternative option, but also as viable and less expensive treatment option with an optimally aesthetic and functional result.     

Periodontal health status in the elderly with different levels of education: a 5-year follow-up study

doi: 10.1111/j.1741‐2358.2010.00437.x Periodontal health status in the elderly with different levels of education: a 5‐year follow‐up study Objective: To assess the association between the periodontal health status and level of education over a 5‐year period among the elderly aged 75 years and older. Background: Oral health among the higher educated is known to be better than among the less‐well educated. On the other hand, the prevalence and severity of periodontal disease has been found to grow with increasing age. Methods: The participants were derived from a population‐based Helsinki Aging Study, a random sample of 76‐, 81‐ and 86‐year‐old elderly. The 170 dentate elderly who underwent clinical oral examinations at baseline and 71 who participated in the follow‐up were included in this study. The data was collected from intraoral and radiological examinations and from a structured questionnaire. Results: Subjects with a higher level of education had more retained teeth than subjects with a lower level of education. According to CPITN index, better‐educated participants had more healthy sextants, but they also had more sextants with periodontal pockets. Radiographic examination showed similar results. Conclusion: Level of education has a clear effect on the periodontal health status in the elderly. More treatment need seems to polarise into those elderly who are better educated as they retain more teeth into old age.     

A comparison of the dental health of Brazilian and Canadian independently living elderly

doi: 10.1111/j.1741‐2358.2009.00340.x
A comparison of the dental health of Brazilian and Canadian independently living elderly Objective: To compare the dental status of Brazilian and Canadian elderly populations with respect to socioeconomic and quality of life factors. Materials and methods: A total of 496 adults aged 60–75 years, having four or more teeth, and physically and cognitively suitable for a clinical oral examination were included. Subjects answered questions concerning their lifestyle and completed the Geriatric Oral Health Assessment Index (GOHAI) questionnaire. Results: In all populations, the majority were females, aged between 60 and 65 years and married. Although the Canadian New Immigrant population had lower mean income, they had more remaining teeth (23.04 ± 6.1), more functional teeth (sound and restored teeth) (14.92 ± 5.7), more sound teeth (15.40 ± 7.6), but more carious teeth (2.97 ± 3.0). The Brazilian population had higher numbers of restored teeth (12.26 ± 6.8) and fewer remaining teeth (17.80 ± 7.6). In all populations, females, married and younger (60–65 years old) adults were more likely to retain 20 or more teeth. The mean GOHAI scores were similar for Canadians (40.55 ± 5.7) and Canadian New Immigrants (39.28 ± 6.5), but were higher than that among Brazilians (31.97 ± 8.9). Conclusions: The numbers of remaining teeth were related to greater education and higher income status for Brazilian and Canadian populations. However, Canadian New Immigrants with lower income and education retained more teeth than the other populations.     

Relationship of number of remaining teeth to health-related quality of life in community-dwelling elderly

Objective: The aim of this study was to evaluate the relationship between number of remaining teeth and health‐related quality of life in community‐dwelling elderly. Subjects: A total of 207 participants who were community‐dwelling, 85 years of age. Data were from a population‐based study of age‐related general and oral health in Fukuoka Prefecture, Japan. Measurements: The Japanese version of the Short Form 36 Health Survey (SF‐36). Results: The mental component score for the participants, from the SF‐36, was higher than the Japanese national norm for those aged ≥70 years. There were no significant differences in the mean of any scores on the SF‐36 by having spouse, living with family, or education level. The mean of the SF‐36 scores of physical functioning (PF) and of the physical component scores were significantly higher in the 85‐year‐old participants with ≥20 teeth than in those with ≤19 teeth (p < 0.05 and p < 0.01 respectively). In addition, a significant difference (p < 0.05) was observed between the mean of participants with ≥20 teeth and those with ≤19 teeth after adjustment for region where the participant lived, activities of daily living (ADL), and sex. The PF (p < 0.001), role‐physical (p < 0.005), bodily pain (p < 0.001), vitality (p < 0.001), social functioning (p < 0.05), and physical component (p < 0.001) scores were significantly higher in participants with a good activities of daily living (ADL) assessment. However, ADL was not associated with the number of teeth. Conclusions: The findings of the present study indicated that 85‐year‐old participants with ≥20 teeth had better subjective physical health than those with ≤19 teeth.     

Biomechanical evaluation of the relationship between postural control and body mass index

Postural stability is crucial in maintaining body balance during quiet standing, locomotion, and any activities that require a high degree of balance performance, such as participating in sports and dancing. Research has shown that there is a relationship between stability and body mass. The aims of this study were to examine the impact that two variables had on static postural control: body mass index (BMI) and gender. Eighty healthy young adults (age=21.7±1.8 yr; height=1.65±0.09 m; mass=67.5±19.0 kg) participated in the study and the static postural control was assessed using the Biodex Balance System, with a 20 Hz sampling rate in the bipedic stance (BLS) and unipedic stance (ULS) for 30s. Five test evaluations were performed for each balance test. Postural control was found to be negatively correlated with increased adiposity, as the obese BMI group performed significantly poorer than the underweight, normal weight and overweight groups during BLS and ULS tests. The underweight, normal weight and overweight groups exhibited greater anterior-posterior stability in postural control during quiet stance. In addition, female displayed a trend of having a greater postural sway than male young adults, although it was evidenced in only some BMI groups. This study revealed that BMI do have an impact on postural control during both BLS and ULS. As such, BMI and gender-specific effects should be taken into consideration when selecting individuals for different types of sporting activities, especially those that require quiet standing.     

Oral health status and change in handgrip strength over a 5-year period in 80-year-old people

Objective: The number of remaining teeth may indicate the extent of life‐long exposure to inflammation, a known risk factor for muscle loss and consequent disability. The aim was to study dental health status as a risk factor for muscle strength loss in very old people. Design: Cross‐sectional and prospective cohort study over a 5‐year follow‐up. Setting: Research laboratory. Participants: One hundred and ninety‐three 80‐year‐old people participated in the baseline examinations. Five years later, 79 survivors were retested. Main outcome measures: Number of remaining teeth, presence of periodontitis and handgrip strength. Results: At baseline, grip strength of men correlated positively with number of teeth but not with the presence of periodontitis. In women, the cross‐sectional associations were not statistically significant. In the prospective analyses, the presence of periodontitis at baseline showed a clear association with a steeper decline in handgrip over the 5‐year follow‐up in both sexes. The values adjusted for gender, height, weight, number of chronic conditions and physical activity were ?28.3% (SE 5.7) among those with periodontitis vs. ?11.9% (SE 3.1, p = 0.015) among those with healthy gingiva. No association between the number of teeth at baseline and change in grip strength over 5 years was observed. Conclusions: The presence of oral inflammation may lead to loss in muscle strength increasing the risk of disability. Therefore, good dental care throughout the life span may decrease risk of disability in old age.     

Oral health status of elderly hospitalised psychiatric patients

doi: 10.1111/j.1741‐2358.2012.00633.x Oral health status of elderly hospitalised psychiatric patients Objectives: This study investigated the oral health status of an elderly mentally ill population hospitalised in a psychogeriatric ward in Athens. Materials and methods: A structured interview recorded sociodemographic and dental data, and an oral examination recorded the status of oral tissues and the existing dentures. The patients’ medical records were examined by a hospital’s physician. Results: One hundred and eleven patients with a mean age of 73 years participated in the study. Almost half of them suffered from schizophrenia. Forty percent were completely edentulous but only 38.6% of them used a pair of dentures. The dentate had an average of 12.9 teeth, 50.7% of them had at least one decayed tooth, 44.8% needed at least one extraction, and only 26.7% had filled teeth. The dental hygiene was poor in 83.6% of the patients. More than 60% of the dentures had a defect. Multiple regression analyses showed that increasing age and dementia were significantly related to fewer remaining teeth, and the use of atypical antipsychotics was related to fewer caried teeth. Conclusion: The oral health of the elderly psychiatric patients was very poor. Access to dental care should improve, and the health care staff should be trained to identify oral problems.
