Arabic version of the Geriatric Oral Health Assessment Index

Objectives: The purpose of this study was to translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into an Arabic version, and to test the validity and reliability of the translated instrument (GOHAI‐Ar) for use among the elderly in Saudi Arabia. Methods: The 12‐item GOHAI was translated into Arabic using the back‐translation technique and performing a preliminary test to determine the comprehensibility and readability of the Arabic language version. A total of 156 elderly patients answered the questionnaire, and underwent a clinical examination by one calibrated dentist. Information on subjects’ socio‐demographic background and oral health conditions was collected. Convergent validity was evaluated by identifying the associations between perceived oral health status, general health status, perceived need for dental care and GOHAI‐Ar scores. Discriminant validity was examined by comparing the GOHAI‐Ar scores and six oral health parameters. Internal consistency was measured by Cronbach’s alpha. Test–retest reliability was assessed by intra‐class correlation coefficient (ICC) and weighted kappa. Factor structure of GOHAI‐Ar was evaluated using principal component factor analysis. Results: The mean GOHAI‐Ar was 32.1 (SD 12.2; range 11–59). Mean GOHAI‐Ar scores were higher for the elderly who rated their oral and general health as good. Subjects with perceived dental treatment needs had a lower mean GOHAI‐Ar score than those without any such needs. The caries experience, number of missing teeth, OHI‐S score, number of pathologically mobile teeth and number of oral lesions were negatively correlated with the GOHAI‐Ar score. The Cronbach’s alpha (0.93) indicated a high degree of internal consistency and homogeneity between items. The ICC for GOHAI‐Ar was 0.95, the weighted kappa coefficient for individual items varied between 0.42 and 0.71, and the correlation coefficients for the 12 items were above 0.70. Factor analysis didn’t support the expected dimensions of the index, and only one factor was found at eigenvalue greater than 1. Conclusions: The findings suggest an excellent reliability and validity of GOHAI‐Ar. Further research is needed to assess the value of this instrument in oral health‐related quality of life studies in Arabic elderly population.

Gerodontology 2011; doi: 10.1111/j.1741‐2358.2009.00360.x
Factors associated with the oral health‐related quality of life in elderly persons in dental clinic: validation of a Mandarin Chinese version of GOHAI Objectives: To translate the original English version of Geriatric Oral Health Assessment Index (GOHAI) into Mandarin Chinese and assess its reliability and validity for use among the elderly in inland China and to explore the factors associated with oral health‐related quality of life (OHRQoL). Methods: The original English version of GOHAI was translated, back‐translated and cross‐culturally adapted. The psychometric properties of GOHAI‐M were assessed in a sample of 263 people aged 60 years and over and OHRQoL was examined in 221 subjects using GOHAI‐M. Multiple regression analysis was conducted. Results: Internal consistency of the GOHAI‐M was excellent (Cronbach’s α : 0.81). Split‐half reliability coefficient was 0.80, and item‐scale correlation coefficient ranged from 0.25 to 0.71. Self‐rated oral health was significantly associated with OHRQoL (r_s = 0.505, p < 0.01). The relation coefficient between GOHAI‐M and self‐perceived need for dental treatment and number of missing teeth were 0.231 and ?0.653, respectively (p < 0.05). Multiple regression analysis found that better OHRQoL was significantly associated with better self‐ratings of oral health (β = 0.497, p = 0.01), number of missing teeth (β = 0.187, p < 0.01) and life satisfaction (β = 0.132, p < 0.05). Conclusion: The Mandarin Chinese version of GOHAI demonstrates acceptable reliability and validity. OHRQoL is associated with self‐rated oral health, number of missing teeth and satisfaction with life.     

Assessment of changes in oral health‐related quality of life among patients with complete denture before and 1 month post‐insertion using Geriatric Oral Health Assessment Index

doi:10.1111/j.1741‐2358.2009.00323.x
Assessment of changes in oral health‐related quality of life among patients with complete denture before and 1 month post‐insertion using Geriatric Oral Health Assessment Index Objective: Geriatric Oral Health Assessment Index (GOHAI) is a 12‐item measure of “patient‐reported oral functional problems” intended for use in the assessment of the effectiveness of dental treatment. Design and Setting: As there is scanty literature available on GOHAI in the Indian population, the present study was undertaken to assess the changes in GOHAI before and 1 month after placement of dentures in completely edentulous patients reporting to a dental hospital at Indore, India. Measurements: The GOHAI questionnaire was completed by the examiner who interviewed the patients (n = 35) before placement of complete dentures and 1 month later. Mean, median values were calculated and the data were analysed using Wilcoxon signed‐rank test. Results: When overall mean was considered, the GOHAI scores increased from 27.48 to 30.19 (p = 0.002; highly significant). Conclusion: Patients reported improvement in functional changes after placement of complete dentures.     

Relationships between Geriatric Oral Health Assessment Index scores and general physical status in community-dwelling older adults

doi: 10.1111/j.1741‐2358.2011.00597.x Relationships between Geriatric Oral Health Assessment Index scores and general physical status in community‐dwelling older adults Objective: The aim of this study was to investigate the relationships between Geriatric Oral Health Assessment Index (GOHAI) and general physical status among community‐dwelling older adults. Background: Geriatric Oral Health Assessment Index is a patient‐centred assessment of oral health for older adults. We hypothesised that GOHAI is a significant indicator of general physical status of older adults. Methods: This study included 354 adults (age, ≥65 years) living independently. Body mass index, handgrip strength and one‐leg standing time with eyes open were used to evaluate the general physical status. Spearman’s rank correlation coefficients were calculated to examine the relationships between the GOHAI scores, its three subdivided categories (physical function, psychological function and pain and discomfort) and each physical status measurement. A stepwise linear regression model was applied with each physical status measurement as the dependent variable and the GOHAI scores and its subdivisions as the principal independent variable. Results: Positive correlations were found between the GOHAI scores, its three subdivided categories and handgrip strength. The physical function category positively correlated with one‐leg standing time. The GOHAI and the pain and discomfort category scores were retained in the final models of stepwise regression for handgrip strength, and significant relationships persisted after adjustments for demographic, psychosocial, medical and dental status. Conclusion: The GOHAI scores and its pain and discomfort category score may be significant indicators of body muscle strength.     

Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City,India

doi: 10.1111/j.1741‐2358.2012.00651.x Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City, India Objective: To assess whether oral health–related quality of life (OHRQoL) is associated with nutritional status in the institutionalised elderly population of Mysore. Background: Malnutrition in the elderly has an evident impact on their general health and quality of life. Analysis of data of the Geriatric Oral Health Assessment Index (GOHAI) and their association with the Mini Nutritional Assessment (MNA) results improves our understanding of the complex relationship between oral health and malnutrition. Materials and methods: The study was conducted among the institutionalised elderly population in Mysore city, Karnataka. Data on socio‐demographic, oral health status were gathered. OHRQoL was evaluated using GOHAI, and malnutrition risk using MNA. Results: Out of 141 elderly, 41.1% were men and 58.9% were women with mean age of 72.2 ± 7.5 years. Mean GOHAI score was 47.03 ± 9.2, with 69.5% had low perception of oral health. Mean MNA score was 9.91 ± 2.4, 15.6% were malnourished, 52.5% were at risk of malnutrition and 31.9% were adequately nourished. A strong association was found between the mean GOHAI and MNA scores. Conclusion: Oral health–related quality of life was associated with nutritional deficit, and it requires a greater integration between dentistry and nutrition in the health promotion of older adults.     

Oral health‐related quality of life of older people from three South American cities

Objective: To describe subjective oral health status and its association with overall health conditions and socioeconomic factors in the elderly (60 years and older) living in the capital cities with the oldest average populations in South America. Background: Oral diseases are a public health problem, frequently neglected in older adults. In recent years, the subjective assessment of psychological and social consequences of the problems related to oral health has been valued. One of the instruments used to estimate the Oral Health‐Quality of Life is the Geriatric Oral Health Assessment (GOHAI). Material and methods: Representative samples from SABE study (1999–2000) of Santiago (n = 1301), Buenos Aires (n = 1043), and Montevideo (n = 1450) aged 60 and over community‐dwelling people. We assessed OH‐QoL (GOHAI), self‐reported missing teeth, denture use, and self‐rated‐health, among other indicators. Logistic regression models(GOHAI < 58) for each city, adjusted by sex and age, were applied. Results: GOHAI average scores were higher in Montevideo (54.8 ± 6.1) than in Buenos Aires (53.1 ± 7.4) and Santiago (49.9 ± 8.6). A pronounced gradient of the oral condition and GOHAI scores were observed within the three‐cities. Denture use ‐less prevalent in Santiago and more common among women‐ is a protective factor against a poor OH‐QoL. Conclusion: Socioeconomic inequalities in oral health status and OH‐QoL are observed in the three cities. The increasing life expectancy emphasizes the need to integrate prevention and treatment efforts, as a way to improve OH‐QoL over the course of a lifetime.     

Oral health-related quality of life: a critical appraisal of assessment tools used in elderly people

Objective: The purpose of this study was to undertake a critical appraisal of oral health‐related quality of life (OHRQoL) measurements used for research in the elderly. Background: A variety of OHRQoL measurements have been developed in the past 20 years as a result of increased concern about the impact of oral conditions on a person’s quality of life. There is need for an assessment aimed at prioritising the recommended measurements to be used for different purposes in the elderly. Materials and methods: Original English language papers using measurements to assess OHRQoL in the elderly were identified from Web of Science, EMBASE, PubMed, Medline and Lilacs databases. The search included all papers published from 1985 to February 2007. The criteria of assessment were: (i) measurement criteria (number of items and domains, and classification of the results found for each measurement); (ii) quantitative–qualitative criteria (frequency, acceptability, reproducibility, reliability, sensitivity and capability of being reproduced in other language versions). Results: In a total of 152 papers selected, 20 measurements were identified. However, only seven fulfilled all the measurement and quantitative–qualitative criteria. Conclusion: Geriatric Oral Health Assessment Index, Subjective Oral Health Status Indicators, Oral Health Impact Profile‐49, Dental Impact on Daily Living, Oral Health Impact Profile‐14, Oral Impact on Daily Performances and German Version of the Oral Heath Impact Profile were considered as instruments of choice to assess OHRQoL in the elderly. The other 13 instruments identified require further research aimed at a validation process and the use of a language other than English.     

TMD and GOHAI indices of Brazilian institutionalised and community-dwelling elderly

Rationale and objectives: Considering the controversy in the literature regarding several aspects of temporomandibular dysfunction (TMD) in elderly populations and the absence of reliable data on elderly Brazilians in this field, this study consisted of an evaluation of TMD prevalence and the self‐perception of oral health among institutionalised and community‐dwelling elderly in São José dos Campos, Brazil. Methods: Two hundred and fifteen community‐dwelling and 185 institutionalised elderly people were evaluated by the Helkimo anamnestic (Ai) and clinical dysfunction (Di) indices and answered a questionnaire using the Geriatric Oral Health Assessment Index (GOHAI). Results: The major prevalence of TMD symptoms was for the Ai0 (symptom‐free) group (69.5%), while the major prevalence of clinical signs was for the DiI (mild) group (56%). Women presented a higher AiII classification than men (χ² test, p = 0.049). Community‐dwelling elderly presented a significantly lower Ai0 classification than the institutionalised ones (Two ratios equality test, p < 0.001). There was no relationship between the institutionalised status and the clinical dysfunction index for Di0 and DiIII classification (Two ratios equality test, p = 0.194 and 0.535 respectively). The institutionalised elderly presented greater (One‐way anova = 0.005) self‐perception of oral health (33.45) than did the community‐dwelling group (32.66). There were only weak Pearson’s correlations among the anamnestic (?33.0%) or clinical (?14.7%) findings by the TMD and GOHAI indices. Symptom‐free (Ai0) institutionalised elderly presented better scores in all GOHAI dimensions and elderly representing an absence of clinical TMD signs (Di0) presented higher GOHAI physical dimension scores in both groups. Conclusions: The prevalence of TMD symptoms among this sample of elderly individuals was relatively low, self‐perception of oral health was reasonable and a weak, inverse correlation was found between TMD signs and symptoms and elderly self‐perception of oral health measured by the GOHAI index.     

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.     

Impact of new prostheses on the oral health related quality of life of edentulous patients

Objective: A study was conducted to evaluate the impact of the placement of complete dentures by using the Global Oral Health Assessment Index (GOHAI). Background: Oral health quality of life indicators can be used to evaluate the effects of dental treatments. Material and methods: The 26 participants were treated in a French University Clinic during 2002. They were randomly divided into two groups. Each group received new prostheses, but evaluation of the quality of life was made at different periods [baseline, denture placement (group 1), 6 and 12 weeks (group 2) after placement]. A questionnaire was used to collect information on patient's satisfaction with the previous and new prostheses. Nonparametric tests were used to test the relationships between patients’ satisfaction or baseline data and GOHAI variations with time as well as to compare mean values of GOHAI within each group. Results: At baseline, the impact of oral health problems was apparent; the mean GOHAI‐Add score was 45.8 (10.2). Six weeks after placement of the new denture, there was no difference in GOHAI scores compared with the initial assessment. An improvement in GOHAI score was observed 12 weeks after the participants received their new dentures (p < 0.05). Change in GOHAI‐Add scores was negatively correlated with the initial GOHAI‐Add score. Patients who preferred the new prosthesis enjoyed a positive change in GOHAI scores (p < 0.001). There was a relationship between participants’ satisfaction with the new dentures and change in GOHAI scores (p < 0.05). Conclusion: The GOHAI can be used to evaluate needs for and effect of the making of new complete dentures.     

Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects

doi: 10.1111/j.1741‐2358.2011.00606.x Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects Objective: To evaluate the reliability and validity of the Japanese version of the Oral Health Impact Profile for edentulous (OHIP‐EDENT‐J) patients. Background: Oral Health Impact Profile for edentulous is an appropriate instrument for assessing the Quality of life (QOL) in edentulous patients. However, the reliability and validity of the Japanese version had not been evaluated. Methods: The study was conducted on 116 edentulous patients (Group A, requiring new dentures, n = 61; Group B, already having dentures, n = 55). Cronbach’s alpha (α) was used to measure internal consistency of the summary scores for OHIP‐EDENT‐J and various subscales in Groups A and B. The interclass correlation coefficient (ICC) and 95% confidence interval of the summary scores for OHIP‐EDENT‐J and subscales were calculated. The summary scores for OHIP‐EDENT‐J in Groups A and B were compared with evaluate content validity. The Spearman’s correlation coefficient between the summary scores for OHIP‐EDENT‐J and the satisfaction with dentures (100 mm VAS) was calculated for Groups A and B to evaluate concurrent validity. Results: The reliability of the summary scores for OHIP‐EDENT‐J was good (α = 0.93). The ICC of the summary scores for OHIP‐EDENT‐J was 0.85. Summary scores for OHIP‐EDENT‐J were significantly different (p = 0.027) between Group A and Group B, with Group A having the higher value. The Spearman’s correlation coefficient for the degree of satisfaction with dentures and the summary scores for OHIP‐EDENT‐J, calculated for Groups A and B (n = 107), was ?0.609. Conclusion: The OHIP‐EDENT‐J, a questionnaire on oral health–related QOL comprising 19 items, showed good reliability and validity for edentulous patients.     

The oral health‐related quality of life in edentulous patients treated with Conventional complete dentures

Objective: To compare the oral health‐related quality of life (OHRQoL) between patients with both maxillary and mandibular complete denture and those with either the maxillary or the mandibular complete denture. Background: Satisfaction of denture wearers can be estimated using the OHRQoL questionnaires like the OHIP‐EDENT and the Geriatric Oral Health Assessment Index (GOHAI). Methods: Two questionnaires were used to compare the OHRQoL between edentulous patients who had conventional removable complete denture on both jaws and those who had on either one of the jaws. Result: The age of the participants ranged from 42 to 75 years, with the mean age of 58 ± 8.12 years. The mean OHIP‐EDENT scores were significantly high among those who wore conventional dentures in both jaws (54.12 ± 5.21), compared with the participants who only had denture either on upper or lower jaw (46.52 ± 7.35). It was noticed that the mean GOHAI score was significantly lower (p < 0.05) among participants who had conventional denture on both upper and lower jaw (28.25 ± 3.67), as compared to those who had conventional denture only on one arch (35.12 ± 2.11). Conclusion: Patients with complete dentures in both jaw (Group I) were less satisfied than patients with single complete denture (Group II). The result obtained in this study shows dissatisfaction with conventional dentures among edentulous patients.     

Oral health-related quality of life--associations with oral health and conditions in Swedish 70-year-old individuals

doi: 10.1111/j.1741‐2358.2011.00495.x Oral health–related quality of life – associations with oral health and conditions in Swedish 70‐year‐old individuals Objective: The aim of this study was to evaluate oral health–related quality of life (OHRQoL) in relation to different chronic oral conditions and perception of oral health among elderly individuals. Background: Health‐related quality of life is important to assess and understand the impact of different diseases and conditions on individuals’ well‐being. Material and methods: Randomly selected 70‐year‐old individuals (N = 561) were included in this analysis. They were clinically examined and answered a questionnaire. Variables used were perceived oral health, satisfaction with appearance of teeth, problems with chewing and dry mouth, burning mouth syndrome, dental anxiety and dental visiting habits. To measure the participants′ perception of the impact of oral conditions on their well‐being, the Oral Health Impact Profile (OHIP‐14) was used. Results: The OHIP‐14 distribution of sum of scores showed a floor effect but revealed acceptable psychometric properties with regard to reliability and validity. Multivariable logistic regression revealed three highly predictive variables for individuals with high OHIP‐14 scores: using dentures, having chewing problems and being dissatisfied with appearance of teeth. Conclusion: Use of dentures, having chewing problems and being dissatisfied with appearance of teeth are associated with high OHIP‐14 sums, indicating strong influence on OHRQoL.     

Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia

doi:10.1111/j.1741‐2358.2009.00344.x
Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia Objective: To explore the differences in oral status, dental attendance and dry mouth problems between patients with long‐term disease with high and low scores on Oral Health Impact Profile 14 (OHIP 14) and how patients cope with oral problems such as xerostomia and a reduced ability to brush their teeth. Background: There has been a lack of studies of oral health and oral health‐related quality of life in the frail elderly within the community services. Materials and methods: A cross‐sectional questionnaire study was conducted with 137 patients receiving home‐care nursing. Structured interviews were conducted by student nurses using OHIP‐14, items from the Xerostomia Inventory and questions concerning dental visit habits, brushing of teeth and data from medical records. Results: Eighty‐three per cent of patients had natural teeth and 60% had only natural teeth. ‘Natural teeth only’ indicated a low score on OHIP‐14. Problems with brushing and items concerning xerostomia indicated a high score on OHIP‐14. Contrasts in the assessments concerning brushing of teeth and xerostomia indicated low priority from the patients themselves and the nursing staff. Conclusion: Community health services should focus upon oral health. Both patients and nurses should assess the need for regular brushing of teeth carried out by home‐care nurses. Assessment and treatment of dry mouth problems should have higher priority.     

Validity and reliability of the Oral Impacts on Daily Performance (OIDP) scale in the elderly population of Bosnia and Herzegovina

doi: 10.1111/j.1741‐2358.2011.00584.x Validity and reliability of the Oral Impacts on Daily Performance (OIDP) scale in the elderly population of Bosnia and Herzegovina Objectives: To adapt the Oral Impacts on Daily Performance (OIDP) index for elderly people in Bosnia and Herzegovina and test its validity, reliability and responsiveness to change. Background: Clinical measures alone may not be adequate for assessing the oral health of individuals. Subjective oral health indicators tested within a particular cultural context may not be relevant across cultures. Materials and methods: The study population comprised 231 free‐living adults aged 65 years or older. The OIDP was cross‐culturally adapted from English into the Serbian language and its psychometric properties were tested. Data were collected using a clinical examination and a questionnaire containing the OIDP. Results: In terms of reliability, Cronbach’s alpha coefficient was 0.82 and the intraclass correlation coefficient 0.88. The very high correlation of OIDP with self‐rated oral health (r = 0.78) verified criterion validity, while construct validity was demonstrated through its significant and graded associations with other subjective health measures. OIDP change scores on a treated subsample showed moderate effect size (0.59) and were associated with perceptions of oral health change, providing evidence for its responsiveness to change. Conclusion: The Bosnian version of the OIDP showed satisfactory validity, reliability and responsiveness to change confirming its appropriateness for use among older populations in Bosnia and Herzegovina.     

Derivation of the short form of the Oral Health Impact Profile in Spanish (OHIP-EE-14)

doi: 10.1111/j.1741‐2358.2012.00613.x
Derivation of the short form of the Oral Health Impact Profile in Spanish (OHIP‐EE‐14) Background and Objective: The Oral Health Impact Profile is the most frequently used and validated of the Oral Health Quality of Life instruments. Several short versions have been developed; and a validation of the OHIP‐49 in Spanish has been published. The objective was to develop the short version of the Oral Health Impact Profile in Spanish (OHIP‐EE‐14). Methods: Cross‐sectional study. One hundred and thirty‐one persons aged ≥60 years attending a social centre for the elderly, residents of a nursing home and persons seeking dental care at a dental school in Mexico City were interviewed and examined. The validity of each of the 49 questions was evaluated, and, to construct the short version, 14 items were selected. The perceived need for dental treatment, number of teeth, presence of coronal caries, root caries, presence of dental plaque and utilisation of removable prosthesis were measured. Internal consistency, repeatability and discriminant validity were calculated. Results: The OHIP‐EE‐14 was reliable (Cronbach’s‐α = 0.918, ICC = 0.825). Significant associations were found between OHIP‐EE‐14 and the number of teeth and perceived need for dental treatment. Conclusions: The OHIP‐EE‐14 is a reliable and valid instrument and can be used in subjects aged 60 years and over from Mexico City.     

The potential benefits of dental implants on the oral health quality of life of people with Parkinson’s disease

Objective: To investigate how dental implants impact on the oral health quality of life of people with Parkinson’s disease (PD). Background: PD is a progressive neurological disorder that can result in a number of oral health care challenges, including denture difficulties. Lack of evidence related to use of implants in PD prompted this study to investigate their use in this group of people. Materials and methods: Nine people with PD were provided with either fixed or removable prostheses using Astra‐Tech implants. Participants completed the socio‐dental questionnaire, ‘The Dental Impact on Daily Living Assessment’ (DIDL) prior to implant surgery, and at 3 and 12 months after provision of the final prosthesis. DIDL comprises two components – the Oral Health Quality of Life Inventory (OH‐QoL) and the Self‐Reported Assessment of Oral Health and Functional Status (SROH). Results: Nine people (with an age range of 54–77 years) had implants placed. The implant success rate was 85 and 81% in the maxilla and mandible, respectively. The OH‐QoL and SROH results (analysed using the one‐way analysis of variance and pairwise multiple comparisons) demonstrated a significant improvement in the domains of eating and satisfaction with the prosthesis after 3 months, which was maintained at the twelve month review. The OH‐QoL indicated a gradual improvement in oral well‐being over the 12‐month period. Conclusion: The oral health quality of life of people with PD was improved by the use of dental implants, indicating this as a viable treatment option.     

Association between oral health, cognitive impairment and oral health-related quality of life

doi: 10.1111/j.1741‐2358.2011.00542.x
Association between oral health, cognitive impairment and oral health–related quality of life Objective: Investigating oral health–related quality of life’s (OH‐QoL) relationship with cognitive state. Background: Oral health affects OH‐QoL and is poor in institutionalised and cognitively impaired people. Material and Methods: This was a cross‐sectional study involving 215 institutionalised elderly (82.9 mean age), who were interviewed, examined and cognitively screened using the Pfeiffer test. Results: Mean GOHAI score was 53.1; only 43.7% of the participants reported having a good OH‐QoL. Needing help with dressing or washing (OR 2.14; p = 0.004), having one to nine teeth (OR 4.65; p ≥ 0.001), eight or less occluding pairs (OR 2.74; p = 0.002), one to three caries (OR 1.85; p = 0.005) and being cognitive impaired (OR 0.54; p = 0.034) were significantly associated with altered OH‐QoL in bi‐variate analysis. Being edentulous (OR 3.18; p = 0.0046), having 1–9 teeth (OR 2.62; p = 0.056) and presenting mild cognitive impairment (MCI) (OR 0.32; p = 0.016) appeared as predictive variables in logistic regression for having an altered OH‐QoL. Conclusions: Participants having MCI had significantly better GOHAI score than cognitively normal residents. Performing cognitive screening parallel to applying any OH‐QoL instrument would make the results more reliable and would benefit cognitively impaired people.     

Impact of dry mouth conditions on oral health-related quality of life in older people

Objective: The aim of the present study was to evaluate the impact of dry mouth conditions on oral health‐related quality of life in frail old people, residents at community care centers. Further, reliability and validity of a visual analogue scale (VAS) for dry mouth symptoms were determined within the study cohort. Background: In old people functional, social and psychological impacts of oral conditions are associated with an overall sense of well being and general health. Subjective dry mouth and reduced saliva flow are common disorders in old people caused by disease and medication. Thus, dry mouth conditions may be determinants for compromised oral health‐related quality of life in old people. Method: In total, 50 old people living at service homes for the old people were asked to answer questionnaires on subjective dry mouth (VAS) and Oral Health Impact Profile (OHIP14) for oral health‐related quality of life. Saliva flow was estimated by absorbing saliva into a pre‐weighed cotton roll. Results: The final study cohort comprised 41 old people (aged 83–91 years). Significant associations were identified between both objective and subjective dry mouth and overall or specific aspects of oral health‐related quality of life. Conclusion: Dry mouth (objective and subjective) is significantly associated with oral health‐related quality of life strengthening the value of monitoring dry mouth conditions in the care of frail old people.
