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

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

Oral mucosal and osseous disorders in frail elders

Objective: This paper reviews the implications of frailty for oral health in old age due to the incidence of oral pathoses following on mucosal atrophy, tooth loss, trauma from dentures, polypharmacy, malnutrition, salivary disorders, degeneration of jawbone and cancer. Background: Frailty as a condition of old age occurs when elders have energy levels below a critical threshold, or when the social or cultural environment is limited. Results: Frail elders are particularly vulnerable to pathoses, but not simply because of old age per se. Oral diseases accompanying frailty are due to a complicated mixture of biopsychosocial changes that accompany old age. Conclusions: Management of oral mucosal and osseous disorders in frail elders requires an understanding of the changes that occur with advancing age.     

Enhancing the quality of life in elderly women through a programme to improve the condition of salivary hypofunction

doi: 10.1111/j.1741‐2358.2011.00594.x Enhancing the quality of life in elderly women through a programme to improve the condition of salivary hypofunction Objective: The purposes of this study were to examine the effects of oral exercise intended to improve the function of the oral cavity in the elderly and their quality of life to pave the way for the development of oral‐health promotion programmes geared towards the elderly. Methods: The subjects were 78 female Koreans who resided in Seoul and were aged 65 years and older. During a 3‐month period, an oral function promotion programme was conducted twice a week, between 10.00 am and 12.00 pm , applying oral exercise suggested by a Japanese public health centre. A survey was conducted by interviewing the selected women to determine the state of their subjective dry mouth, quality of life related to oral health and jaw functional limitation. Their opening, unstimulated whole saliva and pronunciation speed were measured before and after the oral function exercise programme. Results: The subjects showed a significant improvement in subjective dry mouth symptoms, relevant behaviour, the level of discomfort caused by dry mouth and subjective jaw functional limitation during mastication and swallowing and emotional expression after receiving the oral exercise. After the oral exercise, there was a significant increase in mouth opening, unstimulated whole saliva and speaking speed (‘patakala’ pronunciation) after oral exercise. There was also significant progress in their quality of life related to oral health. Overall improvement in subjective dry mouth symptoms and relevant behaviour over time after oral exercise had a positive correlation with the level of improvement in discomfort triggered by dry mouth and mastication. The level of improvement in OHIP‐14 had a positive correlation with the level of overall improvement in dry mouth symptoms and behaviour, the level of improvement in discomfort by dry mouth and that in mastication and swallowing. Conclusion: This study showed the effects of the oral function promotion programme and correlation of oral condition and oral health‐related quality of life. It is suggested that this oral function promotion programme has positive effects on both objective and subjective oral conditions. It is strongly recommended that this programme, along with other oral health promotion programmes, be implemented to improve oral function and oral health‐related quality of life for the elderly.     

Oral lesions in elderly population: a biopsy survey using 2250 histopathological records

Objective: To perform an oral biopsy survey focused on the incidence of oral lesions in Brazilian elderly patients. Methods: A total of 17 329 oral biopsy records were analysed and divided into two age groups: elderly patients, ≥60 years old; and non‐elderly patients, <60 years old. Information about sex, race, age and histopathological diagnosis (categorised in non‐neoplastic and neoplastic lesions) was collected. Differences of diagnosis incidence were tested by comparison between two proportions (binomial test). Results: The incidence of epithelial malignant neoplasms and pre‐malignant lesions in the elderly group was higher than non‐elderly group, as well as autoimmune diseases and salivary gland tumours. The three most prevalent lesions in the elderly group were inflammatory fibrous hyperplasia, squamous cell carcinoma, and fibroma. Conclusion: The distribution of oral diseases using biopsies allows greater accuracy in data about oral health of elderly patients, especially when considering malignant and pre‐malignant lesions.     

Oral health,organic and inorganic saliva composition of men with Schizophrenia: Case-control study

BackgroundSchizophrenia (SCZ) presents complex challenges related to diagnosis and clinical monitoring. The study of conditions associated with SCZ can be facilitated by using potential markers and patterns that provide information to support the diagnosis and oral health.MethodsThe salivary composition of patients diagnosed with SCZ (n = 50) was evaluated and compared to the control (n = 50). Saliva samples from male patients were collected and clinical parameters were evaluated. The concentration of total proteins and amylase were determined and salivary macro- and microelements were quantified by ICP OES and ICP-MS. Exploratory data analysis based on artificial intelligence tools was used in the investigation.ResultsThere was a significant increase in the salivary concentrations of Al, Fe, Li, Mg, Na, and V, higher prevalence of caries (p < 0.001), periodontal disease (p < 0.001), and reduced salivary flow rate (p = 0.019) in SCZ patients. Also, samples were grouped into six clusters. As, Co, Cr, Cu, Mn, Mo, Ni, Se, and Sr were correlated with each other, while Fe, K, Li, Ti, and V showed the highest concentrations in the samples distributed in the clusters with the highest association between SZC patients and controls.ConclusionsThe results obtained indicate changes in salivary flow, organic composition, and levels of macro- and microelements in SCZ patients. Salivary concentrations of Fe, Mg, and Na may be related to oral conditions, higher prevalence of caries, and periodontal disease. The exploratory analysis showed different patterns in the salivary composition of SCZ patients impacted by associations between oral health conditions and the use of medications. Future studies are encouraged to confirm the results investigated in this study.     

A cross-sectional study of oral health and oral health-related quality of life among frail elderly persons on admission to a special oral health care programme in Copenhagen City, Denmark

doi: 10.1111/j.1741‐2358.2011.00486.x
A cross‐sectional study of oral health and oral health‐related quality of life among frail elderly persons on admission to a special oral health care programme in Copenhagen City, Denmark Aim: To describe the oral health and the oral‐health‐related quality of life (OHRQoL) of citizens in Copenhagen City on admission to a specific oral health‐care programme for disabled elderly persons. Further, to analyse how various factors influence the oral health and the OHRQoL among these patients. Methods: A cross‐sectional study of 189 persons (average 85 years) consecutively admitted to a special oral health‐care programme. Clinical data and data from interviews comprising social factors, life‐style, dental visit habits, oral hygiene practices and self‐perceived oral health were collected. A modified index on perceived dysfunction, discomfort and disability due to oral disorders was used. Results: Sixty‐eight per cent had natural teeth, among those 57% had decayed teeth and two out of three wore dentures. Smoking habits influence the number of teeth present and the OHRQoL (p < 0.05) of the patients. Edentulousness, decayed teeth, and presence of dentures did not seem to cause OHRQoL problems, while higher OHRQoL scores (more problems) were reported by those with 1–9 teeth and tooth mobility. Conclusion: OHRQoL of these patients can be increased by removal of loose teeth and provision of dentures to those with very few teeth rather than focus on traditional caries treatment.     

How primary health care professionals and residents assess issues related to the oral health of older persons?

doi: 10.1111/j.1741‐2358.2009.00355.x
How primary health care professionals and residents assess issues related to the oral health of older persons? Background and objectives: It is known that older persons need integrated primary health care. However, oral health may not be a frequent concern of multi‐professional teams taking care of older persons. The aim of the present study was to evaluate knowledge and practices related to oral health care, as reported by professionals and residents in a primary health care service. Material and methods: One hundred and seventy‐three health professionals and residents were assessed in this cross‐sectional study by means of a structured questionnaire containing questions pertaining to oral health practices and beliefs. Participants were grouped based on their professions into “primary health care dentists” or “other primary health care professionals” and based on their working status into “permanent team” or “residents”. Results: Permanent team members (other professionals) assessed and recommended dental care more frequently than residents. Permanent team members (other professionals) also reported that they felt they were able to inform older patients in respect to oral health‐related issues more frequently than did residents (68.7% vs. 31.3%, respectively). Conclusion: Oral health‐related knowledge and beliefs were frequent among non‐dentists primary health care workers, suggesting that primary health care which integrates oral health represents an attainable goal.     

Saliva proteome profiling reveals potential salivary biomarkers for detection of oral cavity squamous cell carcinoma

Oral cavity squamous cell carcinoma (OSCC), which is frequently associated with poor prognosis and mortality, is a leading cause of cancer‐related death worldwide. Discovery of body fluid accessible biomarkers is needed to improve OSCC screening. To this end, we profiled proteomes of saliva from the healthy volunteers, the individuals with oral potentially malignant disorders (OPMD), and the OSCC patients by means of SDS‐PAGE coupled with LC‐MS/MS. In the control, the OPMD, and the OSCC groups, 958, 845, and 1030 salivary proteins were detected, respectively. With spectral counting‐based label‐free quantification, 22 overexpressed salivary proteins were identified in the OSCC group compared with the healthy controls and the OPMD individuals. Among them, resistin (RETN) was subjected to further validation with an independent cohort using ELISA. The data confirmed that the salivary RETN levels in the OSCC patients were significantly higher than that in the healthy or in the OPMD group. Moreover, the elevated levels of salivary RETN were highly correlated with late‐stage primary tumors, advanced overall stage, and lymph‐node metastasis. Our results not only reveal that profiling of saliva proteome is feasible for discovery of OSCC biomarkers, but also identify RETN as a potential salivary biomarker for OSCC detection.     

Analysis of age and gender associated N-glycoproteome in human whole saliva

Background

Glycoproteins comprise a large portion of the salivary proteome and have great potential for biomarker discovery and disease diagnosis. However, the rate of production and the concentration of whole saliva change with age, gender and physiological states of the human body. Therefore, a thorough understanding of the salivary glycoproteome of healthy individuals of different ages and genders is a prerequisite for saliva to have clinical utility.

Methods

Formerly N-linked glycopeptides were isolated from the pooled whole saliva of six age and gender groups by hydrazide chemistry and hydrophilic affinity methods followed by mass spectrometry identification. Selected physiochemical characteristics of salivary glycoproteins were analyzed, and the salivary glycoproteomes of different age and gender groups were compared based on their glycoprotein components and gene ontology.

Results and discussion

Among 85 N-glycoproteins identified in healthy human saliva, the majority were acidic proteins with low molecular weight. The numbers of salivary N-glycoproteins increased with age. Fifteen salivary glycoproteins were identified as potential age- or gender-associated glycoproteins, and many of them have functions related to innate immunity against microorganisms and oral cavity protection. Moreover, many salivary glycoproteins have been previously reported as disease related glycoproteins. This study reveals the important role of salivary glycoproteins in the maintenance of oral health and homeostasis and the great potential of saliva for biomarker discovery and disease diagnosis.     

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.     

Patterns of dental caries and treatment experience in elderly Lithuanians

Objective: The aim of the study was to evaluate patterns of caries experience in a representative sample of Lithuanians, aged 65‐74. Methods: This cross‐sectional study included 301 participants (response rate 54%). Information was obtained from a clinical examination (caries experience, stimulated salivary flow rates and oral hygiene levels) and a questionnaire. The questionnaire comprised questions about oral, general, physical, mental and social health and about background, knowledge, attitudes and lifestyle. The study had a multidimensional approach to negative consequences of disease and positive aspects of health. For bivariate testing, t‐test, ANOVA and Spearman's correlation were used. Factor analysis was combined with linear multiple regression for a multivariate study of caries experience patterns. Results: Elderly Lithuanians were found to have lower levels of edentulousness (range 11‐15%) than elderly people in other European countries. The mean number of missing teeth was also lower than in any of the neighbouring countries. A comparison of dentate and edentulous groups did not show any major differences. Those who reported that they had general disease had higher levels of oral health maintenance. In dentate elderly, caries experience differed according to place of residence, fluoride content in the drinking water, socio‐economic status, gender, lifestyle, and many other factors. The multivariate approach explained 52%. 61% and 55% of the variation in the number of filled or sound teeth (FS‐T), delayed (DT) and missing teeth (MT) respectively. Conclusion: Levels of oral health maintenance and caries experience show substantial variation among elderly Lithuanians, according to many health‐related characteristics. These elderly people require appropriate oral care, just as much as people in other population sub‐groups.     

Oral health-related well-being of the long-term hospitalised elderly

Objective: To investigate oral health‐related well‐being of the long‐term hospitalised elderly as reported by their primary nurses in relation to subject's oral health assessed either by primary nurses or by a clinical dental examination. Background data: Little is known about oral health‐related well‐being of the medically compromised, long‐term hospitalised elderly, most of whom are unable to express their feelings and opinions. Materials and methods: A cross‐sectional study using a questionnaire for primary nurses about oral health and oral health‐related well‐being regarding functional, pain/discomfort‐related, and psychosocial limitations of the subjects (n = 255) and assessment of oral health by clinical examination. The total number of limitations and the number of limitations in each category was calculated. Results: Most (77%) of our subjects were unable to eat normal food. Functional limitations dominated followed by psychosocial and pain/discomfort‐related limitations. Overall assessment by each subject's primary nurse ranked oral health of as good for 9% of subjects, as moderate for 44%, and as poor for 47%. Clinical examination‐based assessment ranked oral health as good for 19%, as moderate for 33%, and as poor for 48% of our subjects, with good oral health being ranked as good for more men than women (26% vs. 16%; p = 0.045). Fewer limitations were recorded for those with better oral health assessed both by primary nurse and by clinical examination. Conclusion: More efforts are called for to maintain the oral health of the long‐term hospitalised elderly so as to improve their well‐being.     

Analysis of oral microbial community and Th17‐associated cytokines in saliva of patients with oral lichen planus

Oral lichen planus (OLP) is a chronic inflammatory disorder of oral mucosa of unknown cause. Microbial infection and dysimmunity appear to play important roles in its pathogenesis. In this study, differences in genetic profiling of salivary microbial communities in two subtypes of OLP and healthy controls were evaluated by means of PCR‐denaturing gradient gel electrophoresis (DGGE). Additionally, ELISA was used to investigate the possible role of Th17 in lesion formation by detecting two related cytokines IL‐17 and IL‐23 in the saliva of OLP patients. When the DGGE profiles were analyzed, the bacterial populations were found to be significantly less rich in subjects with reticular and erosive OLP than in healthy controls. There was significantly less microbial diversity, as denoted by the Shannon index, in saliva samples from subjects with erosive OLP than in those from healthy controls. Cluster analysis and principal component analysis showed that the DGGE profiles formed distinctly group‐specific clusters. Salivary concentrations of IL‐17 in subjects with erosive OLP group were significantly higher than in those with reticular OLP and healthy controls. What's more, significantly positive correlations were observed between salivary IL‐17 concentrations and disease clinical scores. Microbial richness and diversity was negatively correlated with salivary IL‐17 concentrations. These results suggest there is significantly less salivary bacterial diversity and complexity in subjects with OLP han in healthy controls and that the shifted community composition is closely related to an immune cytokine, IL‐17.     

Evaluation of an oral function promotion programme for the independent elderly in Japan

Objectives: The purpose of this study was to provide an oral function promotion programme for the independent elderly and evaluate the changes in oral health status and oral function. Background: Few studies have scientifically analysed and evaluated the effectiveness of oral function promotion programmes provided for the independent elderly. Materials and methods: The subjects were independent elderly females (mean age: 74.6 ± 6.3) recruited from senior citizens’ centres in Tokyo. The intervention group (n = 79) received a 3‐month oral function promotion programme, which included facial muscle and tongue exercises and salivary gland massages. The control group (n = 62) did not receive this programme. Results: In the intervention group, the tongue coating scores decreased and the organoleptic score of oral malodour fell. The amount of food debris in the oral cavity decreased and the tongue dryness improved. Furthermore, the salivary flow rate increased. The length of time for maintaining the tongue in the forward position increased from 11.2 s to 18.7 s, and the number of times for moving the tip of the tongue in a clockwise circular motion, counter‐clockwise circular motion and side‐to‐side motion within 30 s, increased from 14.5 to 20.6, 14.5 to 20.2, and 17.2 to 23.3 respectively. The number of times for movement of the lips significantly improved from 23.0 to 28.8 and the pronunciation of words was observed to be clearer. Conclusion: An oral function promotion programme was effective in improving the oral health status and oral function of an independent elderly population.     

Assessing changes in oral health‐related quality of life and its factors in community‐dwelling older Brazilians

doi: 10.1111/j.1741‐2358.2012.00656.x Assessing changes in oral health‐related quality of life and its factors in community‐dwelling older Brazilians Objective: To describe changes in oral health‐related quality of life and to evaluate the associations of these changes in community‐dwelling older people. Materials and methods: In this longitudinal study a representative sample of 872 older people, living in Brazil, was evaluated during 2004. The follow‐up was carried out during 2008, with 587 older persons evaluated. A questionnaire assessing socio‐demographic information, health history, oral health‐impact profile and number of natural teeth was used. Changes in oral health‐related quality of life were categorized as improvement or deterioration. Data analysis was performed using a hierarchical approach based in a conceptual framework. A hierarchal approach was carried out using Poisson regressions. Results: Older persons living in rural areas, those who reported brushing once a day or less and older persons with fewer natural teeth had an increased chance of reporting deterioration in oral health‐related quality of life. Women and participants who received a minimum wage of less than US$219.50 were more likely to report improvement in oral health‐related quality of life. Conclusion: The results of this study suggest that changes in the oral health‐related quality of life are influenced by many of the variables that were included in the conceptual framework.     

Oral implants in dependent elderly persons: blessing or burden?

doi:10.1111/j.1741‐2358.2009.00314.x
Oral implants in dependent elderly persons: blessing or burden? Background: Implant‐supported (partial) dentures may raise problems in patients who have become dependent on others for daily oral health care. Dental hygienists and general dental practitioners, as well as care providers, volunteer aiders and even health care insurance companies, should anticipate the growing demand for specific oral health care for patients provided with implant‐supported (partial) dentures. Objective: To report three cases of dependent patients and to present recommendations to prevent or resolve implant‐related oral problems. Materials and methods: The three case reports are demonstrating that implant insertion in (dependent) elderly people needs careful consideration. Discussion: When considering implant treatment, some questions should be raised: (1) Is the treatment appropriate in contributing to the patient’s well‐being and quality of life? (2) Is the treatment the most suitable treatment? (3) Does the treatment integrate with the patient’s oral health care plan? (4) Is the patient sufficiently cooperative? (5) Is the patient supported by a well‐functioning oral (self) care assisting network? (6) Is it possible for the patient to regular see an oral health care professional and is oral health care easily accessible in cases of an emergency? Conclusion: Dependent elderly people can benefit from oral implants, providing that adequate oral health care and aftercare can be provided. When indicated, removal of the anchorage structure is easily performed by putting the implants to sleep. All implant patients should be provided with an ‘implant passport’. Regular information and instruction for care providers about the oral condition of the patient are essential.     

Oral mucous membrane flora in patients using saliva substitutes

Salivary substitutes are sometimes valuable for elderly people and radiotherapy patients, and may be used indefinitely. It is possible that this change in the ecology may effect the oral flora. Objective: To analyse the presence of micro‐organisms on oral mucous membranes during use of saliva substitutes. Design: Cross‐over single‐blind study. Setting: Clinic for Maxillofacial Surgery, Malmö University Hospital and Department of Oral Microbiology, Malmö University. Subjects: 19 patients with low salivary secretion who had been radiated for cancer in the head and neck region. Intervention Two saliva substitutes: linseed extract and a carboxymethyl cellulose preparation (Salinum and MAS‐84) were used for 3 week periods. Measurements: Microbial samples taken, processed and analysed. Results: No differences were observed when comparing baseline values with the results after the saliva substitutes and no significant differences between the use of different agents. Conclusion: The study suggests that use of linseed extract and carboxymethyl cellulose preparation during periods of weeks does not influence flora commonly related to caries, periodontitis or infections in the oral mucous membranes.     

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.     

Correlation of serum oestrogen with salivary calcium in post-menopausal women with and without oral dryness feeling

doi: 10.1111/j.1741‐2358.2011.00580.x
Correlation of serum oestrogen with salivary calcium in post‐menopausal women with and without oral dryness feeling Objective: The aim of this study was to verify the association between salivary calcium and serum oestrogen levels with oral dryness in post‐menopausal women. Also, the correlation between these variables was evaluated. Methods: A case‐control study was carried out on 60 selected menopausal women with and without oral dryness feeling (30 as case and 30 as control) conducted in the Department of Oral Medicine and Radiology, Maharishi Markandeshar University, Mullana, India. Paraffin‐stimulated saliva samples were obtained by expectoration. Salivary calcium concentrations were assessed colorimetrically using Arsenazo III reaction. The serum oestrogen concentration was measured using ELISA. Statistical analysis of Student’s t‐test and Pearson correlation was used. Results: There was significant difference in mean values of both salivary calcium concentration and serum oestrogen between case and control groups. The result obtained also showed that an inverse correlation was found between salivary calcium concentration and serum oestrogen levels in both the groups and in total sample size. Conclusion: Oral dryness in post‐menopausal women is associated with high levels of salivary calcium and low levels of serum oestrogen. The concentrations of salivary calcium and serum oestrogen are inversely correlated in post‐menopausal women, regardless of the presence or absence of oral dryness.     

Health-related quality of life in patients with primary Sjögren's syndrome and xerostomia: a comparative study

Objective: To compare the health status of groups of Primary Sjögren's and Xerostomia patients, using the Medical Outcomes Short Form 36 (SF‐36). The SF‐36 is a generic measure, divided into eight domains, used in the assessment of health‐related quality of life. Patients and methods : The SF‐36 was given to 2 groups: Group 1 comprised 43 patients diagnosed with Primary Sjögren's Syndrome (1SS) and an unstimulated whole salivary flow rate (UFR) of <0.1 ml/min). Group 2 (n = 40) reported Xerosiomia but had an UFR >0.2 ml/min. Sub groups of patients in Groups 1 and 2 were compared with community normative data, for the SF‐36 Results: There were trends to suggest lower SF36 scores for 1SS patients but there were no significant differences between the mean domain scores of Groups 1 and 2. 1SS and Xerostomia patients registered lower mean scores across all 8 domains, compared with normative community data. Conclusion: The SF‐36 was unable to detect significant differences between subjects with 1SS and Xerostomia but a larger sample size is required to confirm these findings. The results of this limited study suggest that a disease‐specific measure is required to assess the impact 1SS on health‐related Quality of life (QOL).
