The validity of self-reported number of teeth and edentulousness among Norwegian older adults, the HUNT Study.

BACKGROUND: Number of teeth is an established indicator of oral health and is commonly self-reported in epidemiological studies due to the costly and labor-intensive nature of clinical examinations. Although previous studies have found self-reported number of teeth to be a reasonably accurate measure, its accuracy among older adults ≥ 70 years is less explored. The aim of this study was to assess the validity of self-reported number of teeth and edentulousness in older adults and to investigate factors that may affect the accuracy of self-reports. METHODS: This study included two different samples of older adults ≥ 70 years drawn from the fourth wave of the Trøndelag Health Study (the HUNT Study), Norway. Sample 1 (n = 586) was used to evaluate the validity of self-reported number of teeth and sample 2 (n = 518) was used to evaluate self-reported edentulousness. Information on number of teeth and background variables (education, smoking, cognitive function, and self-perceived general and oral health) were self-reported in questionnaires, while clinical oral health examinations assessed number of teeth, number of teeth restored or replaced by fixed prosthodontics and edentulousness. Spearman and Pearson correlation coefficients, Bland-Altman plot, chi-square test and kappa statistics were used to assess the agreement between self-reported and clinically recorded number of teeth. RESULTS: The mean difference between self-reported and clinically recorded number of teeth was low (- 0.22 teeth), and more than 70% of the participants reported their number of teeth within an error of two teeth. Correlations between self-reports and clinical examinations were high for the total sample (0.86 (Spearman) and 0.91 (Pearson)). However, a lower correlation was found among participants with dementia (0.74 (Spearman) and 0.85 (Pearson)), participants having ≥ 20 teeth (0.76 (Spearman) and 0.67 (Pearson)), and participants with ≥ 5 teeth restored or replaced by fixed prosthodontics (0.75 (Spearman) and 0.77 (Pearson)). Self-reports of having teeth or being edentulous were correct in 96.3% of the cases (kappa value 0.93, p value < 0.001). CONCLUSIONS: Among older Norwegian adults, self-reported number of teeth agreed closely with clinical tooth counts and nearly all the edentulous participants correctly reported having no teeth.

Association Between Tobacco Smoking, Dental Status and Self-perceived Oral Health in Elderly Adults in Colombia.

Tobacco smoking is responsible for several health problems, including mouth diseases. The aim of the present study was to establish the association between smoking and dental status and self-perceived oral health in a large group of elderly Colombian adults. Analysis of 18,937 survey records of participants aged ≥ 60 years old was conducted. Information regarding age, sex, skin color, socioeconomic level, education, marital status, denture use, partial tooth loss or edentulism, Geriatric Oral Health Assessment Index (GOHAI) and tobacco smoking was retrieved from the database. A descriptive analysis and multivariate logistic regression analysis were performed. Half of the participants were edentulous in the maxilla while mandibular teeth were more frequently retained in more than 60% of the participants. After adjusting for sex and age, smoking consistently increased the odds of partial or complete edentulism in the maxilla (OR 1.05; 95% CI 1.02-1.09) and mandible (OR 1.04; 95% CI 1.00-1.08). Nonetheless, the increase in the odds in the mandible was not statistically significant. The habit of smoking was associated with increased tooth loss that in the long-term may result in poor oral health affecting the quality of life of elderly people.

Association between frequency of laughter and oral health among community-dwelling older adults: a population-based cross-sectional study in Japan.

PURPOSE: Oral health has been reported to have an impact on the activities of daily life such as chewing, eating, and laughing, while psychological factors such as depression and loneliness have been reported to affect oral health. Little is known, however, about the association between laughter and oral health in older adults. This study examined the bidirectional association between the frequency of daily laughter and oral health in community-dwelling older Japanese adults. METHODS: Our cross-sectional study employed data from the 2013 Japan Gerontological Evaluation Study's self-reported survey, which included 11,239 male and 12,799 female community-dwelling independent individuals aged 65 years or older. We defined the oral health status by the number of remaining teeth. The association between the self-reported frequency of laughter (almost every day, 1-5 days per week, 1-3 days per month, or almost never) and oral health was examined using logistic regression analysis. RESULTS: The participants with 10 or more teeth were significantly more likely to laugh compared with the edentulous participants, after adjusting for all covariates. Compared with those who almost never laughed, those who laughed 1-5 days per week were significantly less likely to be edentulous. After stratifying by sex, similar results were found only in the men for both analyses. CONCLUSION: There was a significant bidirectional association between frequency of laughter and oral health that was independent of socioeconomic and lifestyle factors among older adults.

Depression, periodontitis, caries and missing teeth in the USA, NHANES 2009-2014.

PURPOSE: This study aimed to investigate the association between self-reported depressive symptoms and oral diseases in US adults, including periodontitis, caries, missing teeth and untreated dental caries. DESIGN: This study was designed as a secondary data analysis of a cross-sectional survey. We conducted descriptive, multivariable logistic and Poisson regression analyses on weighted data. SETTING: US National Health and Nutrition Examination Survey 2009-2014 data. PARTICIPANTS: Individuals aged ≥30 years who completed a periodontal examination and depression screening (n=9799). RESULTS: 21.6% (28.9 million) of adults aged ≥30 years reported depressive symptoms, with a higher prevalence among females, current smokers and participants with lower income and education status. More than half of the adults with moderate depressive symptoms had periodontal diseases, and more than one-third had teeth with untreated dental caries. After adjusting for sociodemographics, behavioural factors, having diabetes and psychotherapeutic medication use, depressive symptoms were associated with poorer oral health. Severe depressive symptoms were associated with higher odds of mild periodontitis (2.20; 99% CI 1.03 to 4.66). For those with mild depressive symptoms, the mean number of missing teeth was 1.20 (99% CI 1.06 to 1.37) times the average of non-symptomatic individuals; and 1.38 times (99% CI 1.15 to 1.66) among individuals with moderate depressive symptoms. CONCLUSIONS: Depressive symptoms were associated with mild periodontitis and a greater number of missing teeth, while having teeth with untreated dental caries was attributed to sociodemographic factors. Awareness of oral health status among patients with depressive symptoms can inform both dental and mental health providers to develop tailored treatment and help patients achieve overall wellness.

The Effects of Dental Status and Chewing Efficiency on the Oral-Health-Related Quality of Life of Nursing-Home Residents.

OBJECTIVE: The aim of this study was to evaluate the effects of dental status and chewing efficiency on the oral-health-related quality of life (OHRQoL) of nursing-home residents. MATERIALS AND METHODS: The study was conducted in nine nursing homes. All eligible participants were included, and general and medical data, information about nutritional status and their dental and prosthetic status were collected. Chewing efficiency was assessed by means of a two-colour mixing-ability test. The simple count version of the Geriatric Oral Health Assessment Index (SC-GOHAI) was used to evaluate participants' OHRQoL, and the Mini-Mental State Examination to classify the presence of cognitive impairment. Univariate and multivariate regression models were used to analyse data. RESULTS: The mean age of the participants was 82.1 (± 9.8) years and most participants suffered from at least very mild cognitive impairment. OHRQoL for all participants (n = 143) and denture wearers only (n = 105) was substantially associated with the type of prosthesis, the presence of natural teeth, the number of functional occluding pairs and dental and denture-related (if applicable) treatment needs. Furthermore, in both model's univariate analysis showed that chewing efficiency also affected OHRQoL. In contrast, multivariate analysis of all participants revealed that only a higher number of functional occluding pairs (C: 0.250; p < 0.001), fewer dental treatment needs (C: -1.733; p = 0.019) and a better nutritional status (C: -1.298; p = 0.048) were relevant for better OHRQoL. For denture wearers, a higher number of functional occluding pairs (C: 0.192; p = 0.011), a better denture condition (C: -2.194; p= 0.003) and a higher body mass index (BMI) (C: 0.145; p = 0.006) were the main variables associated with better OHRQoL among participants. CONCLUSION: Good oral health and oral function, including chewing efficiency, are associated with a high OHRQoL of nursing-home residents. However, few dental treatment needs, well-fitting dentures without treatment needs and a high number of functional occluding pairs seem to be the principal variables for an acceptable OHRQoL of nursing-home residents.

Rehabilitation of the completely edentulous young patient with the "Malo Bridge": A case report.

It is possible to rehabilitate fully edentulous patients with implantsupported fixed or removable prostheses; however, implantsupported fixed prostheses are the gold standard for patients who not prefer to use removable dentures. This case report, prosthetic rehabilitation of a completely edentulous young patient with an implantsupported fixed hybrid prosthesis using the "Malo Bridge" technique is described. A 18 years old male patient was referred to the clinic with complaints of tooth loss, aesthetics, function, and phonetic. A total of 5 implants were placed in both the jaws. Considering that screw holes may cause aesthetic problems due to the Class III occlusion, these problems have been solved with the implant-supported hybrid prosthesis called Malo bridge. With the Malo Bridge design, the patient's aesthetic, functional and phonetic loss was eliminated, patient comfort and quality of life were improved, and patient expectations were met. It is a viable treatment option to rehabilitate completely edentulous jaws with a cross relationship and increase interarch distance using Malo Bridge to support a fixed prosthesis.

Oral health status and oral health-related quality of life among patients with type 2 diabetes mellitus in the United Arab Emirates: a matched case-control study.

BACKGROUND: Nearly a quarter of the population in the UAE has type 2 diabetes mellitus (T2DM), and this medical condition is associated with poorer oral health. The effects on oral health-related quality of life (OHRQoL), however, have not been examined in this population. Therefore, the objective of this study was to assess the impact of oral health problems, such as caries and periodontitis, on OHRQoL among Arab patients with and without T2DM. METHODS: This matched case-control study included 88 diabetic and 88 non-diabetic participants recruited from University Dental Hospital Sharjah and University Hospital Sharjah, UAE. Participants completed a sociodemographic questionnaire as well as the Oral Health Impact Profile short form (OHIP-14), which measures OHRQoL. Clinical examinations were conducted to assess participants' dental caries status, using the Decayed Missing Filled Teeth (DMFT) Index, and periodontal condition, via clinical attachment loss (CAL) dichotomized to CAL < 3 mm and CAL ≥3 mm. Linear regression models were used to identify the association among OHIP domains, clinical attachment loss, DMFT scores, and diabetes status. RESULTS: The mean age of participants was 43.0 years. A significantly (p = 0.01) higher proportion of diabetic patients (23%) had a CAL ≥3 mm than non-diabetic patients (10%). No significant differences in OHIP scores were observed between diabetic and non-diabetic patients. The results of the linear regression suggested that irrespective of diabetic status, DMFT scores were significantly associated with physical disability, physical pain, psychological discomfort, and psychological disability, as well as total OHIP scores. CAL was significantly associated with the handicap domain. Among non-diabetic patients, OHIP scores were significantly associated with DMFT scores in five OHIP domains (functional limitation, physical disability, physical pain, psychological discomfort, psychological disability), as well as total OHIP scores. Among diabetic patients, CAL was significantly associated with both the social disability and handicap domains, while only the handicap domain reached statistical significance among non-diabetic patients. CONCLUSIONS: Participants who had decayed teeth, irrespective of their diabetic status, reported substantial physical and psychological impacts on OHRQoL. CAL also had a significant impact on OHRQoL, being primarily associated with the OHIP handicap domain in both diabetic and non-diabetic patients.

Validation of a modified version of the Spanish Geriatric Oral Health Assessment Index (GOHAI-SP) for adults and elder people.

BACKGROUND: The Geriatric Oral Health Assessment Index (GOHAI) was developed and validated in 1990 and translated into Spanish in 1999. Since then, the original version has been used in numerous studies, but it has not been re-evaluated in terms of language in the new generations of older adults. The purpose of this study is to confirm the validity of the Spanish version of the Geriatric Oral Health Assessment Index (GOHAI-SP) after three decades to be used as part of an ongoing field trial. METHODS: The GOHAI-SP was pilot tested in a focus group to confirm linguistic comprehension. A version with minor language changes was administered to individuals with metabolic syndrome aged 55-75 years from one health care district in southern Spain as part of an ongoing field trial (PREDIMED-Plus). Clinical evaluation included assessment of dental and periodontal status. The psychometric properties of the GOHAI-SP were evaluated through stability and internal consistency measures, and concurrent and discriminant validity were assessed. RESULTS: The new version of the GOHAI-SP was administered to 100 individuals. The application time was reduced by 7 min. The alpha value for reliability was 0.87. The item-scale correlation coefficients ranged from 0.54 to 0.75, and the test-re-test correlation for the total score was 0.75. There were inverse correlations between GOHAI-SP scores and the number of lost teeth and the decayed-missing-filled teeth index (p < 0.001). CONCLUSIONS: The GOHAI-SP questionnaire remains a valid and useful tool to assess oral health-related quality of life in primary health care settings. A linguistic update of the questionnaire brought improvements to the instrument application. TRIAL REGISTRATION: The PREDIMED-Plus trial is registered in the ISRCTN registry with reference number ISRCTN89898870. Registration date: 4th July 2014.

Impact of Seniors Centers on oral health-related quality of life of older adults.

OBJECTIVE: This study evaluated the oral health-related quality of life (OHRQoL) of older adults participating or not in Seniors Centers (SC). METHODS: Two independent samples were compared: older adults who participate in SC (n = 124) and older adults who visited Primary Healthcare Centers (PHC) and do not participate in SC (n = 164). The data collected consisted of sociodemographic (sex, age, educational level, marital status, family income) and psychosocial characteristics-Sense of Coherence (SOC), anxiety and depression using HADS, happiness-, and oral clinical evaluation-use and need of dental prosthesis and decayed (D), missing (M), or filled (F) teeth. The resulting OHRQoL was evaluated using the Oral Health Impact Profile (OHIP-14). The Mann-Whitney test was used to assess the associations between the independent variables and the OHIP-14. Poisson regression models were also used in the analyses (α=0.05). RESULTS: In the PHC, of the 270 individuals invited to participate in the study, 164 (60.7%) were interviewed and clinically examined; while in the SC, of the 166 individuals invited to participate in the study, 124 (74.7%) were interviewed and clinically examined. After adjustments for sociodemographic, psychosocial and clinical factors, we found that the impact on OHRQoL was 2.8 times higher (95%CI 2.0-4.2) for older adults who did not participate in SC. CONCLUSION: Older adults who participated in SC showed better perception on OHRQoL, independently of sociodemographic, psychosocial and clinical factors.

Loss of Functional Dentition is Associated with Cognitive Impairment.

BACKGROUND: Although tooth loss is known to increase the risk of cognitive impairment and dementia, few studies have investigated the association between functional teeth including rehabilitated lost teeth and cognitive functionObjective:We investigated the associations of the numbers of functional teeth and functional occlusal units with cognitive impairment and cognitive function in late life. METHODS: The current study was conducted as a part of the Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD), a community-based elderly cohort study. We analyzed 411 participants who have agreed with the additional dental exam. Geriatric psychiatrists and neuropsychologists administered the Consortium to Establish a Registry for Alzheimer's disease Assessment Packet Clinical and Neuropsychological Assessment Battery to all participants, and dentists examined their dental status. RESULTS: Higher number of functional teeth (OR = 0.955, 95% CI = 0.914-0.997, p = 0.037) and higher number of functional occlusal units (OR = 0.900, 95% CI = 0.813-0.996, p = 0.042) were associated with lower odds of cognitive impairment. When we analyzed these relationships separated by the location of teeth, only the numbers of functional teeth (OR = 0.566, 95% CI = 0.373-0.857, p = 0.007) and functional occlusal units (OR = 0.399, 95% CI = 0.213-0.748, p = 0.004) in the premolar area were associated with lower odds of cognitive impairment. CONCLUSION: Loss of functional teeth and functional occlusal units (especially in the premolar region) were associated with increased cognitive impairment.

Can chronic oral inflammation and masticatory dysfunction contribute to cognitive impairment?

PURPOSE OF REVIEW: This article provides an overview of current literature focused on oral health and cognitive impairment in older adulthood, focusing in particular on whether oral inflammation, tooth loss and masticatory dysfunction might increase the risk of cognitive impairment in this age group. RECENT FINDINGS: There is now general acceptance that cognitive impairment contributes to poor oral health, largely through detrimental changes in behaviours related to maintaining good oral hygiene. There is more limited evidence for the reverse causal direction, but at least some studies now suggest that inflammatory mechanisms, tooth loss and masticatory dysfunction each have the potential to contribute to cognitive decline. SUMMARY: Poorer oral health significantly correlates with cognitive dysfunction, and at least some studies suggest that there may be a bi-directional causal relationship. Randomized controlled trials assessing cognitive abilities in relation to oral hygiene or oral health interventions, or provision of removable or fixed (implant-supported) dentures, are encouraged.

Quality of life related to tooth loss and prosthetic replacements among persons with dependency and functional limitations.

Objectives: To examine if tooth loss or treatment with different prosthetic replacements are associated with oral health-related or health-related quality of life (OHRQoL or HRQoL) among persons with dependency and functional limitations.Material and Methods: Comparisons between results of questionnaires and clinical data (number of teeth, Eichner index, presence, type, and condition of prosthetic replacements) from a population of 180 individuals with dependency and functional limitations sampled from the register of increased financial support in Norrbotten County, Sweden.Results: The associations between clinical variables and the questionnaire responses were weak overall, e.g. Spearman's rho was 0.162 (p = .033) for correlation between number of teeth and GOHAI, 0.094 (p = .249) for number of teeth and OHIP, -0.070 (p = .356) for complete dentures and GOHAI, and -0.108 (p = .185) for complete dentures and OHIP.Conclusions: The weak associations between clinical variables and questionnaire results in the present study suggest that good results on measured QoL do not necessarily indicate good oral health. As we cannot expect this specific population to report oral disorders by themselves, regular check-ups are necessary.

Impact of seniors centers on oral health-related quality of life of older adults

ABSTRACT OBJECTIVE This study evaluated the oral health-related quality of life (OHRQoL) of older adults participating or not in Seniors Centers (SC).

After adjustments for sociodemographic, psychosocial and clinical factors, we found that the impact on OHRQoL was 2.8 times higher (95%CI 2.0-4.2) for older adults who did not participate in SC. CONCLUSION Older adults who participated in SC showed better perception on OHRQoL, independently of sociodemographic, psychosocial and clinical factors.

Relationship between tooth loss, low masticatory ability, and nutritional indices in the elderly: a cross-sectional study.

BACKGROUND: Low masticatory ability and the resulting decrease in intake of masticable foods can result in undernutrition. The present study investigated the relationship between tooth loss, low masticatory ability, and nutritional indices in the elderly. METHODS: The data analyzed in this study were retrieved from the baseline data of the 2007 Fujiwara-kyo study, a prospective cohort study of community-dwelling elderly individuals. Subjects included 1591 men and 1543 women, both with a median age of 71 years. The maximum occlusal force was measured as an objective index of masticatory ability. Foods were divided into five groups based on hardness: Group 1 (bananas, etc.), 0.53 kg; Group 2 (boiled rice, etc.), 1.22 kg; Group 3 (raisins, etc.), 2.93 kg; Group 4 (raw carrots, etc.), 4.38 kg; and Group 5 (beef jerky), 6.56 kg. To obtain a subjective index of masticatory ability, a questionnaire-based survey was conducted to determine whether subjects could masticate foods within each group. As nutritional indices, serum albumin levels and body mass index (BMI) data were used. RESULTS: The median number of teeth was 21. The proportion of subjects for whom all five food groups were masticable showed a significant decrease in the number of teeth in both males and females. Logistic regression analysis showed that, after adjustment for confounders, no significant relationships were observed between the number of teeth and the masticatory ability with nutritional indices in males. In females, a maximum occlusal force of 100 to 300 N (OR = 1.65; 95% CI = 1.06-2.55) or less than 100 N (OR = 1.95; 95% CI = 1.15-3.31) showed a significant correlation with serum albumin levels below 4.4 g/dL (reference: 500 N or more). In addition, the masticability of all five food groups showed a significant correlation with BMI < 21.0 kg/m2 (OR = 0.62; 95% CI = 0.46-0.85) in females. CONCLUSIONS: A low number of teeth was associated with low masticatory ability in both males and females. Low masticatory ability was associated with low plasma albumin levels and low BMI in females. Not smoking, maintaining grip strength, preventing cancer, and masticatory ability are important for preventing undernutrition.

Prospective cohort of adult oral health in Piracicaba, SP, Brazil.

OBJECTIVE: To describe the methodological aspects of a Prospective Cohort Study of adult oral health in Piracicaba, Brazil. RESULTS: This Prospective Cohort Study evaluated adults (20-64 years old) between the years of 2011 and 2015, in Piracicaba, São Paulo, Brazil. The main objective was to evaluate the risk factors for tooth loss in adults. Data were collected at households and selected via probabilistic sampling, through clinical examination of caries, considering as variables the decayed, missing and filled permanent teeth index, need for caries treatment, periodontal disease (Community Periodontal Index and Periodontal Attachment Loss), use and need for dental prosthesis, and presence of visible biofilm. A questionnaire about demographic, socioeconomic and health habits, use of dental services, self-perceived quality of life (Oral Health Impact Profile-14) and health literacy (14-item Health Literacy Scale) was also employed. In 2011, 248 adults participated, and in 2015, 143 (follow-up rate = 57.7%). Despite the follow-up sample loss, most sociodemographic characteristics remained in the participant sample: for example, women (72.0%) (p = 0.534), family income between R$545,00 and R$1090,00 (63.9%) (p = 0.920), above 11 years of education (53.1%) (p = 0.200) and belonging to middle class (67.1%) (p = 0.909).

The experience among patients with multiple dental loss as a consequence of treatment for head and neck cancer: A qualitative study.

OBJECTIVES: To explore the experience among patients with multiple dental loss as a consequence of treatment for head and neck cancer. METHODS: Semi-structured qualitative interviews were conducted with a purposive sample of fifteen people with head and neck cancer, who had multiple teeth removed as part of their tumour resection or extracted pre-radiotherapy. The interviews were digitally recorded and transcribed for analysis by two researchers, independently. RESULTS: The interview data were categorised into four themes: 1. Pretreatment experience of being informed that teeth had to be removed, 2. Impact of dental loss post-treatment, 3. Coping with dental loss, and 4. Getting dentures and implants. Patients receiving primary radiotherapy felt the time between being informed of requirement for dental extractions and actual extractions was short. Dental loss was detrimental to all patients in terms of eating, speaking, socially and their intimate lives. CONCLUSIONS: Patients whose primary treatment was surgery, appeared more accepting of dental loss. Whereas, those having primary radiotherapy, there seemed to be a focus on prevention of radiotherapy-induced complications, with limited choices and recognition on post-treatment dental functionality. This study showed the negative impact of dental loss on patients' quality of life. CLINICAL SIGNIFICANCE: Dentists should be aware of the post-treatment implications of dental loss on patients' lives; presenting this, as well as the clinical advantages for extractions, to aid decision-making. Patients should be informed of the lack of conclusive research evidence regarding pre-radiotherapy dental extraction. There should also be clear pathways regarding post-treatment dental-related rehabilitation.

Personality, xerostomia and OHRQoL among 35-54-year-olds.

OBJECTIVE: Personality characteristics mean that people may interpret similar symptoms differently, complicating the measurement of self-reported oral health, and so we tested the hypothesis that controlling for aspects of personality makes a difference to the association between xerostomia and oral-health-related quality of life. MATERIAL AND METHODS: A cross-sectional study was conducted of a representative adult population sample in Dunedin (New Zealand). Data were collected on xerostomia, OHRQoL and personality characteristics, using (respectively) the 5-item Shortened Xerostomia Inventory (SXI), the OHIP-14 and the Positive and Negative Affect Schedule (PANAS). Negative binomial regression was used to model the association between the SXI and the OHIP-14 scores, and models with and without the PANAS score were compared. RESULTS: The participation rate was 51.3%, with complete OHIP-14 data available for 250 individuals (56.5% female). The SXI score (mean 6.9, sd 1.8) was strongly and positively associated with the OHIP-14 score (in both models), as was the PANAS negative affect score in the second model, which also explained slightly more of the observed variance than the first model. However, the difference in model deviance fell short of the amount required to reject the hypothesis that adding the PANAS variables to the model made a significant difference. CONCLUSIONS: Considering aspects of personality in investigating OHRQoL remains a theoretically important undertaking, but adjusting for it in analyses of associations between xerostomia and OHRQoL is unlikely to be necessary.

Number of remaining teeth and health-related quality of life: the Korean National Health and Nutrition Examination Survey 2010-2012.

OBJECTIVES/AIMS: With the Euro-Qol-5 dimension (EQ-5D) system, we investigated the relationship between the number of remaining teeth and QoL using data from the Korean National Health and Nutrition Examination Survey (KNHANES), 2010-2012. A total of 17,417 participants, more than 19 years old, were finally included in this study (men = 7394 and women = 10,023). Through this study, we have discovered that the remaining teeth affect overall health and that the fewer number of them may indicate a lower quality of life, as well. The quality of life according to the number of remaining teeth was assessed among Koreans using the Euro-Qol-5 dimension (EQ-5D) system. METHOD: The Euro-Qol-5 dimension (EQ-5D) system was used to measure the health-related QoL. Its five dimensions included mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The respondents were asked to choose one of the followings: G 1, no problems; G 2, some problems; and G 3, problematic, to best describe their health status for the five dimensions. Then, we assigned low QoL to G2 + G3 and high QoL to G1. We used age, gender, economic income, educational level, residence, and marital status for the demographic variables and, drinking, smoking, exercise, BMI, and metabolic syndrome for health behaviors. Multiple logistic regression analysis was performed to examine the odds ratios (ORs) and confidence intervals (CIs) for the high QoL (G1) on the five categories of EQ-5D according to the number of remaining teeth. On the basis of the 0-15 remaining teeth group, we drew a comparison of the QoL between the 16-20 and 21-28 remaining teeth groups. RESULTS: Subjects with 21-28 remaining teeth had higher QoL scores and had higher ORs of high QoL, especially for mobility (OR = 1.256, 95% CI = 1.056-1.495), self-care (OR = 1.441, 95% CI = 1.096-1.894), and usual activities (OR = 1.241, 95% CI = 1.022-1.508, respectively), than those with 0-15 remaining teeth after adjusting for age, sex, body mass index, smoking, drinking, exercise, income, education, and metabolic syndrome. ORs from the high QoL had the tendency to increase as the number of remaining teeth increased (all p for trend < 0.05). However, there was no relationship between the number of remaining teeth and QoL in the pain/discomfort and anxiety/depression dimensions. CONCLUSION: The number of remaining teeth was associated with QoL, and subjects who had more teeth obtained higher QoL scores. The subjects in the high QoL group were especially associated with the components of EQ-5D such as mobility, self-care, and daily living.

[The absence of functional dentition is associated with the lack of commitment to oral functions among Brazilian adults]. / A falta de dentição funcional está associada ao comprometimento das funções bucais entre adultos brasileiros.

The scope of this study was to identify if the absence of functional dentition (FD) is associated with a lack of commitment to oral functions/daily activities among Brazilian adults. For this purpose, data from the National Survey of Oral Health (referred to as SB Brasil 2010) was used. FD was evaluated by the criterion proposed by the WHO (at least 20 teeth in the mouth). The Oral Impacts on Daily Performance (OIDP) questionnaire was used to evaluate daily activities/oral functions. Descriptive, bivariate (chi-squared) and multiple (logistic regression) analysis was conducted, and the odds ratio estimated with a 95% confidence interval (OR/CI95%). The research evaluated 9,564 adults, of which 2,200 adults (20.5%) were considered to have poor FD, and at least one of the daily activities/oral functions evaluated had an impact among 55% of adults. The lack of FD between adults was associated (p ≤ 0.05) with the impact on speech (1.88/1.33-2.64) and being ashamed to smile or talk (1.35/1.00-1.83). A considerable prevalence of lack of FD was identified, this absence being associated with the lack of commitment to the daily activities/oral functions. Dental rehabilitation of patients with a lack of FD should consider the restoration of these lost oral functions (speech and being ashamed to smile or talk).

Objetivou-se identificar se a falta de dentição funcional (DF) está associada com o comprometimento das funções bucais/atividades diárias entre adultos brasileiros. Para isto, foram utilizados dados da Pesquisa Nacional de Saúde Bucal - SB Brasil 2010. A DF foi avaliada pelo critério proposto pela Organização Mundial de Saúde (pelo menos 20 dentes na boca). O instrumento Impactos Odontológicos nos Desempenhos Diários (IODD) foi utilizado para avaliar as atividades diárias/funções bucais. Análises descritivas, bivariadas (Qui-quadrado) e múltiplas (Regressão Logística) foram realizadas, sendo estimado o odds ratio e o intervalo de confiança 95% (OR/IC95%). Foram incluídos e avaliados 9564 adultos. Foram considerados sem DF 2200 adultos (20,5%). Tiveram impacto em pelo menos uma das atividades diárias/funções bucais avaliadas, 55,0% dos adultos. A falta de DF entre adultos foi associada (p ≤ 0,05) com o impacto na fala (1,88/1,33-2,64) e vergonha ao sorrir ou falar (1,35/1,00-1,83). Uma prevalência considerável de falta de DF foi identificada, esta ausência foi associada às atividades diárias/funções bucais (fala e vergonha ao sorrir e falar). A reabilitação dentária de pacientes sem DF deve considerar a devolução destas funções bucais perdidas (fala e vergonha ao sorrir ou falar).
