Factors associated with edentulousness in an elderly population in Valencia (Spain)

Modelling analysis of dietary behaviors and oral health status to assess the impact on the mental well-being of elderly individuals: a cross-sectional survey study

Background and objective

Global aging is becoming a pressing concern, with a heightened focus on the mental well-being of the elderly population. The mental health of the elderly is influenced by a plethora of factors such as physical health, social support, lifestyle, and psychological aspects. This study investigates the influence of oral health and eating behaviors on depression, anxiety, and dementia in elderly individuals aged 65 and older in China. The aim is to determine the effect sizes of these factors and establish a foundation for implementing tailored intervention strategies.

Study design and methods

The cross-sectional survey study employed data from the 2020 follow-up of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) released in April 2020. The study included a cohort of 3,188 eligible older adults. Seven aspects of oral health were assessed, encompassing the evaluation of the number of teeth, dental restorations, tooth brushing habits, occurrence of tooth pain, as well as cheek or jaw pain. Additionally, 17 items pertaining to eating behaviors were examined, covering dietary aspects such as staple foods, vegetables, fruits, tastes, and the use of cooking oils. The study assessed depression and sleep through 11 items, with higher scores reflecting a predisposition toward depression. A scoring threshold of over 27 identified individuals in the group prone to depression. Anxiety levels were assessed through seven items, where higher scores denoted a predisposition toward anxiety. Participants scoring above 0 were categorized into the anxiety-prone group. Cognitive function was assessed through seven items, with higher scores suggestive of a propensity toward dementia. Participants with scores exceeding 8 were categorized into the dementia-prone group. Rank-sum tests and chi-square tests were employed for the univariate analysis of variations in depression, anxiety, and dementia among elderly individuals with varying oral health and eating behaviors. Variables demonstrating statistical significance in the univariate analysis were further examined in logistic regression analysis.

Results

This study uncovered a correlation between the oral health and dietary behaviors of middle-aged and elderly individuals and their vulnerability to depression, anxiety, and dementia. Our findings showed that about 7.62% of middle-aged and elderly individuals in China were prone to depression. Meanwhile, around 49% of this population had inadequate teeth to chew and digest properly, and nearly 10% lacked dental restorations. Elderly individuals who had dental surgery had a 50% lower risk of depression compared to those who did not (OR = 0.58). Additionally, 36.7% of this group were prone to anxiety, and 7.53% were at risk of developing dementia. Elderly individuals who brushed their teeth at least twice a day and maintained oral hygiene were less likely to develop anxiety and dementia, with odds ratios of 0.72 and 0.78, respectively. This study conducted in China revealed that among individuals aged 65 and older, 22% reported experiencing tooth pain, while 11% reported experiencing cheek or jaw pain. Controlling tooth, cheek, or jaw pain significantly diminished the likelihood of anxiety in elderly population, with odds ratios of 0.79 and 0.69, respectively. The study also uncovered that consuming an adequate amount of fresh vegetables on a daily basis was highly advantageous in preserving the mental well-being of elderly individuals, and might reduce the risk of depression by 32.5%, anxiety by 50.3%, and dementia by 50%. Elderly individuals could potentially prevent anxiety and dementia by consuming an adequate amount of fruits daily. Conversely, a diet high in salt and spice was potentially associated with an increased risk of anxiety in this population. Furthermore, middle-aged elderly individuals (under 80) exhibited a potentially higher susceptibility to anxiety compared to older elderly individuals (aged 80 and above).

Conclusion

An immediate imperative exists to enhance oral health education, elevate oral hygiene standards, and guarantee prompt dental restoration among middle-aged and elderly populations in order to mitigate their susceptibility to depression, anxiety, and dementia. Safeguarding the mental health of elderly individuals necessitates the coordination of diverse disciplines, encompassing dentistry, nutrition, and public health expertise.

Edentulism and Individual Factors of Active Aging Framework in Colombia

BACKGROUND

While edentulism remains a serious public health problem for older adults in Colombia, few analyses have been conducted from the framework of active aging as a part of the positive discourse of aging. This study analyzed complete edentulism and its relationship with determinants including personal, behavioral, and health systems and social services.

METHODS

This study included a total of 19,004 older adults. We used univariate, bivariate, and multivariate logistic regression type scores to investigate the relationships between the variables. The personal determinants included basic (Barthel scale) and instrumental activities of daily living (Lawton scale), public transportation, functional limitations, self-perceived health, and health problems. The behavioral factors included alcohol and tobacco use, mini nutritional tests, and physical activity. The last determinant was the healthcare system, while social services access included dental services. The analysis also included sociodemographic variables.

RESULTS

The results revealed significant associations for the variables of the three determinants, including the risk of malnutrition (odds ratio [OR]=1.15), functional limitation (OR=1.15), moderate physical activity (OR=1.08), and access to dental services (OR=2.31). Sex, years of education, and race were also risk factors, among other variables. Personal determinants, behavior, and use and access to health services were related to edentulism in older adults.

CONCLUSION

These findings support the need to include different analyses of edentulism from multicausality and to understand the oral cavity and the living conditions of aging adults.

Edentulous disparities among geriatric population according to the sexual difference in South Korea: a nationwide population-based study

The proportion aged 60 years or older in the world's population is expected to double by 2050. In general, they have many complex diseases and poor oral health status. Oral health is one of the important health indicators of elderly people and it is affected by diverse factors, such as socioeconomic status. In this study, sexual difference was considered as an associated factor that is closely related to edentulism. The sexual difference might be more influential within the geriatric population because of lower economic and educational backgrounds at this stage. Edentulism was significantly higher among elderly females than males when combined with the education level. The lower the level of education, the higher the prevalence of edentulism as much as 24 ~ 28 times, especially in females (P = 0.002). These findings suggest a more complex relationship between oral health, socioeconomic status, and sexual difference.

Self-reported morbidities, nutritional characteristics, and associated factors in institutionalized and non-institutionalized older adults

BACKGROUND

As the world's population ages and people live longer, it seems important to ensure that older people have a good quality of life and positive subjective well-being. The objective of this study is to determine socio-economic, health and nutritional characteristics of institutionalized and non-institutionalized elders in the province of Marrakech.

METHODS

This study was conducted among 368 older adults in the province of Marrakech between March 2017 and June 2019. Of all participants, 180 older adults reside in a public institution and 188 of them live in their own homes. Data on health conditions, nutritional status, functional and socio-economic characteristics were collected. Data was analyzed using SPSS Statistics for Windows, Version 16.0. Statistical significance was set at p < 0.05.

RESULTS

Institutionalized elders were illiterate (80.0%), had low incomes (95.5%), and unmarried (73.3%), they reported also no children (56.1%) and no health insurance (98.9%). Institutional residents suffered from malnutrition (22.2%), hearing impairments (35.6%) and severe edentulism (43.3%). There was no significant difference between both groups on daily activities and depression. A multivariate analysis identified a model with three significant variables associated with non-institutionalized elders: health insurance (P = 0.001; OR = 107.49), number of children (P = 0.001; OR = 1.74) and nutritional status (p = 0.001; OR = 3.853).

CONCLUSIONS

This study shows that the institutionalization of older adults is considerably induced by various factors such as nutritional problems, lack of health insurance and family structure. To mitigate the effects of this phenomenon, home care strategies and preventive actions should be implemented to delay the institutionalization of older adults and therefore keep them socially active in their own homes.

Factors associated with oral health-related quality of life of institutionalized elders

This study aimed to evaluate the correlation between two Oral Health-Related Quality of Life (OHRQoL) questionnaires (the Oral Health Impact Profile (OHIP-14) and the Geriatric Oral Health Assessment Index (GOHAI)) and to investigate the factors associated with the OHRQoL of institutionalized elderly individuals. A cross-sectional multicenter study was performed with 344 institutionalized elderly individuals residing in two Brazilian cities. Six trained researchers interviewed the elderly individuals. Sociodemographic data were collected from medical records. Dental caries experience and the use of and need for dentures were recorded through oral examination performed by two trained examiners. A Likert scale (1-5 points) was used to assess general health and self-perceived oral health. The number of chewing cycles needed to chew a portion of peanuts was used to assess the swallowing threshold. The OHIP-14 and GOHAI were used to evaluate OHRQoL, and statistically significant correlations were assessed using Spearman's correlation test (p < 0.05). Poisson regression (p < 0.05) was used to investigate the association of OHRQoL with independent variables. Scores on the OHIP-14 (7.57 ± 8.63) and GOHAI (32.46 ± 3.85) were strongly and inversely correlated (r2 = -0.671, p < 0.001), although these measures were associated with different factors. A higher OHIP-14 total score (worse OHRQoL) was associated with female gender, a greater number of healthy teeth, worse self-perceived general health and oral health, and a lower swallowing threshold (p < 0.05). A higher GOHAI total score (better OHRQoL) was associated with a greater number of filled teeth, better self-perceived oral health and a greater swallowing threshold (p < 0.05). In conclusion, worse OHRQoL among institutionalized elderly individuals is associated with worse self-perceived oral health and a greater swallowing threshold.

Evaluation of the quality of life and satisfaction in patients using complete dentures versus mandibular overdentures. Systematic review and meta-analysis

Background

The World Health Organization (WHO) recognizes edentulism as a physical impairment that results in a negative impact in the daily activities.

Objective

The study aimed to compare the satisfaction and the quality of life, in patients treated with implant retained overdentures with two mandibular implants (IOD) against those with mandibular conventional complete dentures (CCD).

Methods

Different search strategies were used to screen for articles in Pubmed/Medline, Cochrane Library and Scielo of the last 17 years (2003–2020). The keywords used were: “quality of life OR satisfaction” AND “complete denture OR conventional denture” AND “overdenture OR implant retained.”

Results

Six articles and two more were added by manual search. The population was 400 in the CCD and 412 for IOD. The mean age was 64.3 ± 6.41 years. The group was comprised of 283 men and 427 women. The scores obtained in the visual analog scale (VAS) before and after the treatment were statistically significant in favor of the IOD for overall satisfaction, (WMD: 12.329; 95% CI: 4.873 to 19.784, p‐value = 0.001), comfort, speech and stability. For esthetics and chewing there was non‐significant improvement while hygiene worsened for the IOD. For the comparison after the treatment between both treatment modalities a statistically significant improvement was found in overall satisfaction (WMD: 14.408; 95% CI: 8.589 to 20.226, p‐value < 0.001), comfort, speech, chewing and stability in favor of the IOD but not in esthetics or hygiene.

Conclusions

This systematic review and meta‐analysis show the superiority of the IOD, despite is not achieved in all aspects.

Physical and psychological states interfere with health-related quality of life of institutionalized elderly: a cross-sectional study

Background

Nursing home elders experience many problems that may influence their quality of life, in example of cognitive, mental, nutritional and physical disabilities. Concerning about elders’ wellbeing may help them living with dignity. This study aimed to investigate factors associated with Health-Related Quality of Life (HRQoL) of institutionalized elders in a capital city of Brazilian Northeast.

Methods

A cross-sectional study was conducted with 125 institutionalized elders living in the metropolitan region of João Pessoa (Brazil). The following variables were tested regarding their association with the elders’ HRQoL: Socio-demographic characteristics; Performance of daily-living activities, Frailty status, Cognitive status, Nutritional status, Self-perception of oral health and Depression status. Hierarchical multiple Poisson loglinear and binary logistic regressions analyses were performed in order to assess the impact of each independent variable on HRQoL, considering a significance level of 5%.

Results

The median of HRQoL of institutionalized elders was 64. Multivariate regression models showed that retirement, frailty and depression were statistically associated with poor HRQoL (p < 0.05). Not-frail elderly and less depressed were more likely to present higher HRQoL scores.

Conclusions

Lower HRQoL of institutionalized elderly is associated with decline of physical and psychological states. Institutions should be advised to plan and implement actions that would improve the HRQoL of institutionalized elderly.

[Socioeconomic inequalities in health among the elderly population in Spain]

OBJECTIVE

To examine socioeconomic inequalities in health in the older population in Spain.

METHOD

A systematic search and review of the literature published between 2000 and 2017 in English and Spanish was conducted in Social Science Citation Index, Sociology Database, Scopus, PubMed and Embase. Primary and secondary studies analysing these inequalities in Spain were included. Two researchers were responsible for the selection of the studies and the extraction of the information (first author, year of publication, region, design, population/sample, socioeconomic and health indicators used, and main results).

RESULTS

A total of 89 articles were included, corresponding to 87 studies. Of the studies, 81.6% were cross-sectional, 88.5% included only non-institutionalised population and 35.6% were carried out at a national level. The studies analysed social inequalities in the following health indicators: functional status (n=29), morbidity (n=19), self-perceived health (n=18), mental and emotional health (n=10), cognitive status (n=7), quality of life (n=9), mortality (n=15) and life expectancy (n=2). Socioeconomic inequalities were detected in all of them, although the magnitude varied depending on the socioeconomic and health indicator used. The educational level and the ecological indexes were the indicators that detected more inequalities in health. The impact of inequalities by sex was different in functional status, morbidity, self-perceived health, mental and emotional health and mortality.

CONCLUSION

There are socioeconomic inequalities in health among the elderly population and their magnitude varies by sex in some of the health indicators. The increase in educational level and the maintenance of sufficient pensions can be key policies that contribute to the reduction of inequalities in this population group.

[Social inequalities in health among the elderly population: review of indicators used in Spain]

OBJECTIVE

To identify the indicators of social position used to evaluate inequalities in health among the population aged 65 and over in Spain.

METHOD

A systematic search of the literature published in English and Spanish since 2000 in health and social databases was carried out. Primary and secondary studies analyzing these inequalities in Spain were included. The indicators used were identified, as well as the advantages and limitations pointed out by the authors. The main findings were synthesized in a review of the literature.

RESULTS

We included 87 studies, described in 89 articles. The socioeconomic indicators employed were both individual and ecological. Among the former, educational level was the most analyzed socioeconomic variable (n=73). Other individual variables used were occupation (n=17), objective economic level (n=16), subjective economic level (n=4), housing and household material wealth (n=6), relationship with work activity (n=5), and mixed measures (n=5). Among the ecological indicators, simple (n=3) and complex indices (n=7) were identified. The latter had been constructed based on several indicators, such as educational level and unemployment. Inequalities in multiple health indicators were analyzed, self-perceived health being the only indicator assessed according to all the socioeconomic indicators described.

CONCLUSIONS

A wide variety of indicators is identified for the evaluation of social inequalities in health among the elderly population. There have not been sufficiently assessed from a gender perspective; this is a line of interest for future research.

Halitosis and associated factors in institutionalized elderly persons

Abstract Objective: to evaluate the prevalence of halitosis and associated factors in institutionalized elderly persons. Methods: a sectional study was performed with 268 elderly persons from 11 long-term care institutions in Natal in the northeast of Brazil. Data collection included an oral epidemiologic examination and questions about self-perception of oral health, as well as a consultation of medical records and the application of a questionnaire to the directors of the institutions. Halitosis was measured using the organoleptic test. The independent variables were oral, sociodemographic, institutional, general health and functional conditions. Bivariate analysis was performed using the Pearson chi-square test and Fisher's exact test, and the magnitude of effect was verified by the prevalence ratio for the independent variables in relation to the outcome, with a 95% confidence level. Results: the prevalence of halitosis was 26.1%, which was exhaled by the mouth in 98.57% of cases and by the nose in 10% of cases. Prevalence was 43% higher among non-white individuals (p=0.006); 65% higher among those living in non-profit institutions (p=0.039); 52% higher in elderly persons with oriented cognitive status (p=0.047); 41% higher in elderly persons with root caries (p=0.029); 62% higher in those who did not use dentures (p=0.046); 57% lower in edentulous persons (p<0.001); and 73% higher in elderly individuals with tongue biofilm (p=0.001). Conclusion: The occurrence of halitosis in institutionalized elderly persons was similar to other studies, but there was an expressive number of extrabuccal cases and an association with oral health problems, as well as sociodemographic, institutional and functional factors.

Missing Teeth and Prosthetic Treatment in Patients Treated at College of Dentistry, University of Dammam

The percentage of completely and partially edentulous patients and their prosthetic treatment at the Department of Substitutive Dental Sciences (SDS), College of Dentistry, University of Dammam, were investigated. Panoramic radiographs and medical records of adult patients (n = 479, mean age 45.9 years, and range 25-96 years) treated in 2011-2014 were examined. 6% of the patients were completely edentulous, 8% had single jaw edentulousness, and 74% were partially edentulous. Edentulousness was significantly correlated with age and the number of missing teeth was significantly higher among males (p < 0.026). Diabetes was significantly associated with complete edentulousness, single edentulous jaw (p value 0.015), and partial edentulousness (p value 0.023). Kennedy class III was the most frequent class of partial edentulousness in single and/or both jaws (p = 0.000). Patients having class I and/or class II were treated most often with removable partial dentures (RPD) (p = 0.000), while patients having class III were treated with fixed partial dentures (FPD). It was found that complete edentulousness increases in older age and the number of missing teeth was significantly higher among males. Kennedy class III was most common in both upper and lower jaw and was treated more often with FPD than with RPD.

Mechanical strength and fracture point of a dental implant under certification conditions: A numerical approach by finite element analysis

STATEMENT OF PROBLEM

Implant prosthodontics provides high-quality outcomes thanks to recent technological developments and certification procedures such as International Organization for Standardization (ISO) 14801. However, these certification tests are costly, and the result is highly uncertain as the influence of design variables (materials and structure) is still unknown. The design process could be significantly improved if the influence of design parameters were identified.

PURPOSE

The purpose of this in vitro study was to use finite element analysis (FEA) to assess the influence of design parameters on the mechanical performance of an implant in regard to testing conditions of ISO 14801 standard.

MATERIAL AND METHODS

An endosseous dental implant was loaded under ISO 14801 testing conditions by numerical simulation, with 4 parameters evaluated under the following conditions: conditions of the contact surface area between the implant and the loading tool, length of the fixation screw, implant embedding depth, and material used for implant stiffness. FEA was used to compare the force that needed to reach the implant's yield and fracture strength.

RESULTS

A dental implant's fracture point can be increased by 41% by improving the contact surface area, by 20% depending on the type of material, by 4% depending on the length of the fixation screw, and by 1.4% by changing the implant embedding depth.

CONCLUSIONS

FEA made it possible to evaluate 4 performance parameters of a dental implant under ISO 14801 conditions. Under these conditions, the contact surface area was found to be the major parameter influencing implant performance. This observation was validated experimentally in a fatigue test under ISO 14801 conditions.

Comparative Study of the Oral Health Profile of Institutionalized Elderly Persons in Brazil and Barcelona, Spain

Abstract Objective: To compare the oral health profile of institutionalized elderly persons in Brazil and in Barcelona, Spain, by gender and country of residence. Methods: A cross-sectional study was performed of individuals aged 65 years and above (n=1,440), resident in the health region of Barcelona and in Brazil. Two surveys and exams relating to the oral health status of institutionalized elderly persons in Brazil (in 2008) and in Barcelona, Spain (in 2009) were carried out. Periodontal disease, tooth loss and dental caries were analyzed, considering age and cognitive ability. The sample was stratified by gender and country. Bivariate and multivariate Robust Poisson Regression models were used to obtain adjusted Prevalence Ratios (aPR), and a 95% confidence interval (95%CI) was employed. Results: In Barcelona, men and women had a higher prevalence of periodontal illness: Men - calculus (aPR:1.5; CI:1.08-2.19) and pocket (aPR:2.05; CI:1.43-2.93) results. Women - calculus (aPR:2.4; CI:1.77-3.24) and pocket (aPR:3.2; CI:2.29-4.53) results. In Barcelona there was a lower prevalence of edentulism (aPR:0.49; CI:0.37-0.65) and functional edentulism (aPR:0.49; CI:0.40-0.60) among men. The same results were found among women with a lower prevalence of edentulism (aPR:0.49; CI: 0.41-0.58) and functional edentulism (aPR:0.42; CI: 0.30-0.49). Conclusions: A poor state of oral health of men and women was observed in both countries, with the elderly from Barcelona having worse periodontal health and the elderly from Brazil having greater tooth loss.

Prevalence and pattern of partial edentulism among dental patients attending College of Dentistry, Aljouf University, Saudi Arabia

Objective:

The current study aimed to determine the prevalence and pattern of partial edentulism among dental patients attending the College of Dentistry, Aljouf University, Saudi Arabia.

Patients and Methods:

A total of 142 patients were selected, and the prevalence of partial edentulism among the selected patient was recorded. Patients were grouped into three age groups; Group I: 21–30 years, Group II: 31–40 years, and Group III: 41–50 years. Kennedy's classification was used to determine the pattern of partially edentulous arches. Modification areas were not included in the assessment to avoid complexity. Data was analyzed using the Statistical Package for the Social Sciences version 20.0 for windows.

Results:

The results showed that the occurrence of Kennedy Class III partial edentulism was 67.2 % in the maxillary arch and 64.1% in the mandibular arch. Followed by Class II in both maxillary and mandibular arch with an average of 16.3 % in maxillary arch and14.8% in the mandibular arch. Based on these results, class III has the highest prevalence in group II (31- 40 years). Class I and class II have the highest incidence among group III Patients (41–50 years).

Conclusions:

Among selected patients, Class III dental arch was the most prevalent pattern in maxillary and mandibular arches. Class IV being the least dominant pattern between all classes. There are a rise in Kennedy Class I and Kennedy Class II pattern and a decline in Class III and Class IV with an increase in age.

The impact of edentulism on oral and general health

An adequate dentition is of importance for well-being and life quality. Despite advances in preventive dentistry, edentulism is still a major public health problem worldwide. In this narrative review, we provide a perspective on the pathways that link oral to general health. A better understanding of disease indicators is necessary for establishing a solid strategy through an organized oral health care system to prevent and treat this morbid chronic condition.
