Orthodontic Status and Association with Oral-Health-Related Quality of Life-A Study of 16-Year-Old Norwegians with a Cleft Lip and Palate

OBJECTIVE

To assess the association between clinical orthodontic indicators and oral-health-related quality of life, adjusted for socio-demographic factors, focusing on 16-year-old patients with cleft lip and/or palate (CL/P).

PARTICIPANTS

One hundred and twenty-two patients with CL/P, representing cleft-lip (CL), cleft-palate (CP), unilateral/bilateral cleft-lip-palate (UCLP/BCLP), enrolled in the national CLP-Team, Bergen, Norway.

METHOD

A cross-sectional study by two orthodontists assessing the number of teeth, intermaxillary sagittal relation (ANB-angle), dental arch and occlusion of 16-year-old patients with CL/P. All completed a digital questionnaire including self-reported socio-demographic variables, OHIP-14 questionnaire and dental aesthetics. Cross-tabulations with Pearson's Chi-square test were used to identify associations between self-reported OHRQoL and socio-demographic and clinical indicators. Multiple variable analyses were conducted with binary logistic regression analysis using the odds ratio (OR) and 95% confidence interval (CI) to assess associations between OHRQoL and clinical indicators adjusted for socio-demographic variables. Ethical approval was granted by the regional ethics committee.

RESULTS

Patients with UCLP and BCLP had poorer clinical indicators compared to patients with CL and CP (p < 0.05). A total of 80% of the patients had OHIP-14 > 0. The highest oral impact was reported for psychological domains and articulation and the least for functional domains. Respondents with BCLP and those with poor intermaxillary relationships (ANB < 0°) reported a high impact on OHRQoL (p < 0.05). No statistically significant associations between other clinical indicators and socio-demographic variables such as gender, educational aspiration, and place of residence were reported.

CONCLUSIONS

The study revealed an association between severe cleft diagnosis, missing teeth, misaligned teeth, negative overjet, and poor OHRQoL, but a statistically significant association was found only between OHRQoL and poor intermaxillary sagittal relations (unfavorable profile). To improve OHRQoL among patients with clefts, there is a need for an individual follow-up and prioritization of oral healthcare.

The impact of unmet treatment need on oral health related quality of life: a questionnaire survey

BACKGROUND

Based on the present global burden of oral diseases, unmet dental needs affect a more significant population worldwide. It is characterised by the need for dental care but receiving delayed or no care. The contributing factors include lack of knowledge about oral health, its consequences, and the availability of dental services. We need to find out the scale of the problem of unmet dental needs for the south Indian population. Therefore, the objective was to determine the relationship between the presence of oral disease and the quality of life-related to oral health using the OHIP-14 tool.

METHODS

The unmet dental requirements of the south Indian population were determined using a cross-sectional questionnaire survey. Close-ended questions were used to obtain data from two investigators trained to record the answers from the patients. The data was collected using the OHIP-14 questionnaire, which consists of 14 items divided into seven domains with two questions each. Physical pain, psychological impairment, physical disability, psychological disability, social disability, and disability were all considered. An additional analysis of artificial neural network (ANN) was done.

RESULTS

The response rate was 100 per cent. N = 1029 people replied to the questionnaire about their unmet dental needs. N = 497 (48.3%) were men, whereas N = 532 (51.7%) were women. The average age was 31.7811.72. As their current occupation, most of the included subjects (60.1%) were students. The respondents had no known personal habits and a mixed diet (94.93%). The average BMI was 24.022.59 (14-30.9). OHIP was present in 62.3% of the population. The average OHIP-14 severity score was 10.97. (8.54). The severity and degree of unmet dental need were substantial (p0.01) due to pain in the mouth/teeth/gums, malocclusion, and gum bleeding. The most common OHIP-14 domains affected by unmet oral needs were psychological discomfort, psychological limitation, social limitation, and feeling handicapped. The analysis of ANN revealed that high OHIP scores were primarily attributed to dental caries, poor oral health, and dental aesthetics.

CONCLUSION

The severity and degree of unmet dental needs were significant among the south Indian population. The most common oral health status that impacted OHIP-14 domains were pain, malocclusion, and bleeding gums. These patients were significantly impacted by psychological discomfort and social limitations and felt handicapped.

The impact of health education interventions on oral health promotion among older people: a systematic review

BACKGROUND

One of the most common pathologic changes in older people is oral and dental problems. The oral health of older people is a public health concern. Promotion of good oral health for this cohort will have beneficial impacts on the longer-term quality of life. This study aimed to identify the types of health education interventions for the oral health of older people and to determine their effects on the oral and dental health of older people.

METHODS

Potential articles were retrieved from four electronic databases (PubMed/Medline, Scopus, Web of Sciences, and Embase) up to 31 September 2022 in English without limit of time. Experimental and quasi-experimental interventional studies investigating the impact of educational interventions on oral and dental health among older people over 60 years old in both sexes were considered. The quality assessment tool was the Effective Public Health Practice Project (EPHPP).

RESULTS

In the initial search, 1104 articles were retrieved. Finally, according to the inclusion criteria, 23 studies (seventeen randomized controlled trials (RCT) and six quasi-experimental studies) were reviewed. In this review, educational interventions for older people and their caregivers are classified. Theoretical frameworks were used in only three interventions related to older people. Outcome measures were both self-reported and objective measures. Fifteen of the included studies were of moderate quality.

CONCLUSION

This review provides evidence that the use of oral and dental health educational interventions was effective in improving the oral health of older people. Educational interventions were carried out both among older people and among their caregivers. Although a variety of interventions were used in the reviewed studies, more lectures were used in the interventions related to older people. In the interventions related to caregivers, in addition to lectures, practical education was also used. It is recommended to perform higher quality studies for assessing the effectiveness of interventions in this field.

The Relationship between Oral Health-Related Quality of Life and Body Mass Index in an Older Population from Southern Italy: The Salus in Apulia Study

BACKGROUND

The assessment of oral health-related quality of life (OHRQoL) evaluated the impact of an individual's oral health on the patient's physical and psychosocial status. We evaluated the association between subjective OHRQoL, measured with the Oral Health Impact Profile-14 (OHIP-14) questionnaire, and unfavorable body mass index (BMI) (i.e., too high or too low) in a large population-based study on older adults from Southern Italy. Moreover, we assessed which of the seven OHIP-14 domains was the most strongly associated with an unfavorable BMI.

METHODS

We used data on a subpopulation of the Salus in Apulia Study, including 216 older adults. BMI < 18.4 kg/m2 and >30 kg/m2 were classified as unfavorable, while values between 18.5 and 30 kg/m2 were classified as ideal.

RESULTS

A higher OHIP-14 total score increased the risk of an unfavorable BMI (odds ratio (OR): 1.08, 95% confidence interval (CI): 1.01-1.15). In the model adjusted for age, sex, education, hypertension, carbohydrate consumption, and alcohol consumption, this finding was confirmed with a higher OHIP-14 total score increasing the risk of an unfavorable BMI (OR: 1.10, 95% CI: 1.01-1.22), and higher age linked to a decreased risk of an unfavorable BMI (OR: 0.89, 95% CI: 0.82-0.97). In a random forest regression model, the most important predictive domains/sub-scales of OHIP-14 in the mean decrease in the Gini coefficient for unfavorable BMI were, in order of decreasing importance, physical pain, functional limitation, psychological discomfort, physical disability, social disability, psychological disability, and handicap.

CONCLUSIONS

In older age, negative OHRQoL, particularly linked to the physical pain domain, increased the risk of being underweight or overweight and obesity.

Dimensional structure of the OHIP-14 and associations with self-report oral health-related variables in home-dwelling Norwegians aged 70

OBJECTIVES

The primary objective of the present study was to investigate the dimensional structure of the OHIP-14 in a sample of elderly Norwegians. A secondary objective was to describe associations between the exposed OHIP-14 dimensions and additional self-report oral health-related variables to assess the dimensions' criterion validity.

MATERIALS AND METHODS

A survey questionnaire including the OHIP-14 and additional self-report oral health-related measures was completed by 325 home-dwelling Norwegians aged 70+. Exploratory factor analysis was used to investigate the dimensional structure of the OHIP-14 in this sample. Bivariate correlations were used to describe associations between the exposed OHIP-14 dimensions and additional self-report oral health-related variables.

RESULTS

Three dimensions named psychosocial impacts, oral function impacts and general function impacts were revealed. Convergent and discriminant validity of these dimensions were largely supported, and internal consistency reliability for each dimension was good. Statistically significant associations were found between the exposed dimensions and additional self-report oral health-related variables, supporting the dimensions' criterion validity.

CONCLUSIONS

A three-dimensional structure of the OHIP-14 was exposed and validated in the present study sample. Since different aspects of oral health-related quality of life (OHRQoL) may be perceived and weighted differently in various populations, suggestions for future research include more profound investigations of the construct validity of the OHIP-14 and similar instruments assessing OHRQoL. Such research should include an exploration of various dimensions and the weights given to them through qualitative research in the target population(s).

Increased Oral Dryness and Negative Oral Health-Related Quality of Life in Older People with Overweight or Obesity

This cross-sectional study was to evaluate the association between the oral health-related quality of life (OHRQoL) of older Thai people with obesity and oral health indicators. General and oral conditions were assessed. Oral dryness was determined using the Xerostomia Inventory-11 (XI-11) and clinical oral dryness score (CODS). OHRQoL was evaluated by the oral health impact profile (OHIP-14). Participants were aged 60-86 years; 73 (59.3%) were overweight or obese, and 50 (40.7%) were normal weight. Older patients with obesity had almost four times the rate of hypertension (OR = 3.59; 95%CI:1.34-9.60; p = 0.002), more missing teeth (p = 0.025), and higher CODS (p = 0.014) than those without obesity. The total XI-11 scores were positively associated with the total CODS, after adjusting for BMI (r = 0.267, p = 0.003). Those with obesity had almost three times the tendency for a negative OHRQoL compared with the non-obese (OR = 2.73; 95%CI:1.12-6.71; p = 0.04). After adjusting for all related factors, the chances of predicting an OHIP-14 score of four based on obesity and total XI-11 score were 4.42 (95%CI:1.57-12.47; p = 0.005) and 1.11 (95%CI:1.02-1.20; p = 0.013), respectively. Obesity had an increasingly undesirable negative impact on the OHRQoL of older Thai people and was influenced by BMI and oral dryness.

The Influence of Oral Health Factors on the Quality of Life in Older People: A Systematic Review

BACKGROUND AND OBJECTIVES

The number of people aged 65 years or older is growing substantially. As a result of increased health burden and tooth retention, more oral health problems are expected in this age group. A poor oral health-related quality of life (OHQoL) can compromise a person's psychological state, social relationships, personal beliefs, and physical health. The aim of this systematic review was to identify oral health factors associated with OHQoL in people aged 65 years or older and to give a comprehensive overview of the body of literature for each oral health factor separately.

RESEARCH DESIGN AND METHODS

A comprehensive search was performed in five databases. The following terms were used as index terms or free-text words: "Oral Health," "Quality of Life," "Older People." Two researchers independently assessed studies for eligibility based on predefined criteria.

RESULTS

Of 3,702 references retrieved from the databases, 68 studies were eligible and included (9 randomized clinical trials, 6 cohort studies, and 53 cross-sectional studies). All results were reported descriptively. OHQoL in people aged 65 years or older is positively associated with higher number of teeth, higher number of occluding pairs, implant-retained overdentures, and the shortened dental arch concept and negatively associated with xerostomia, orofacial pain, and poor chewing ability. In the current literature, there is no consensus on the association between edentulism, caries, and periodontal conditions and OHQoL.

DISCUSSION AND IMPLICATIONS

Having a functional dentition (either natural or prosthetic) is important for a good OHQoL, whereas painful or functional complaints are associated with impaired OHQoL.

Educational inequalities in access to fixed prosthodontic treatment in Norway. Causal effects using the introduction of a school reform as an instrumental variable

OBJECTIVES

Equality in access to dental services, independent of level of education, is an important aim of Scandinavian welfare policy. In Norway, this policy is the main justification for a dental public subsidy scheme for adults. An important part of the subsidy scheme is to cover the cost of fixed prosthodontic treatment, including implant-based crowns and bridges for premolars, canines and incisors. A stated policy goal is to secure equal access to everybody in need of these services, independent of their level of education. The aim of this study was to estimate the causal effect of education on the probability of receiving fixed prosthodontic treatment in the adult Norwegian population.

METHODS

During the period 1960-1972, all municipalities in Norway were required to increase the number of compulsory years of education from seven to nine years. We used this education reform as the instrumental variable to create exogenous variation in the individual's number of years of education. The education data were combined with data from the Norwegian Health Economics Administration, which contained our outcome variable. Our sample included individuals with 9 years education or less. Altogether 113 237 individuals were included in the study.

RESULTS

For men, the first stage regression coefficient was 0.87 (confidence interval: 0.82-0.92). This means that the reform resulted in 0.87 additional years of education. For men, the probability of receiving fixed prosthodontic treatment increased by 0.67 percentage points per additional year of schooling. For women, the first stage regression coefficient was 0.84 (confidence interval: 0.79-0.88). The second stage regression coefficient was small (= 0.0022) and not statistically significant at a conventional level.

CONCLUSION

From a welfare policy point of view, for men, the subsidy scheme has not succeeded to redistribute resources so that dental services are accessible independent of their social status.

History of Inflammatory Bowel Disease and Self-Reported Oral Health: Women's Health Initiative Observational Study

Background and Objective: Both periodontal disease and inflammatory bowel disease (IBD), are chronic inflammatory conditions, which are mediated by a complex interplay among a dysbiotic microbiota, dysregulated host immune-inflammatory responses, and lifestyle factors. Despite substantial differences in physical and chemical environments, rather strong correlations have been detected between microbial compositions of the oral cavity and stool. In this study, we tested the hypothesis that oral health conditions are affected by the presence of IBD. Materials and Methods: We analyzed the data from 73,621 women who were enrolled in the Women's Health Initiative observational cohort study and completed a follow-up questionnaire that surveyed oral health status specifically at year 5. Among these, 880 reported IBD at the baseline, including 47% who were symptomatic cases and 27% who were on immunosuppressive treatment. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for the association of IBD and medication status for self-reported oral health outcomes, using logistic regression models, adjusted for selected covariates. Results: IBD was not associated with periodontal disease history itself in a multivariable model; however, poorer self-rated oral health was modestly associated with the presence of IBD (OR = 1.15, 95% CI: 1.01-1.30). Likewise, more frequent eating limitations due to teeth were associated with the presence of IBD history (OR = 1.22, 95% CI: 1.07-1.39). When IBD cases were limited to those who were symptomatic, the associations with these two self-rated oral health outcomes were more pronounced with ORs of 1.28 (95% CI: 1.07-1.54) and 1.36 (95% CI: 1.07-1.54), respectively. Immunosuppressive treatment had little effect on these risk estimates. Conclusions: Among this nation-wide cohort of women 50-79 years of age, history of IBD was associated with poorer perceived oral health status.

Oral health-related quality of life and associated factors among older people in short-term care

Objectives

It is well known that oral health status is associated with oral health‐related quality of life (OHRQoL) in the general population. The aim of this study was to describe and analyse OHRQoL among older people in short‐term care and its associated factors.

Materials and Methods

This cross‐sectional study included 391 older people in 36 short‐term care units. Data were collected via clinical oral assessments, questions about self‐perceived oral and general health, Katz Index of Activities of Daily Living (Katz‐ADL) and the Revised Oral Assessment Guide (ROAG). OHRQoL was measured using the Oral Health Impact Profile (OHIP‐14). Multivariate logistic regression models were applied in the analysis.

Results

Poor OHRQoL was reported by 34% of the older people. Associated factors were swallowing problems according to ROAG; quite poor/poor self‐perceived physical, psychological and oral health; and being a woman.

Conclusions

There is an association between OHRQoL and older people's self‐perceived health according to the OHIP‐14. This indicates the importance of early detection of oral health problems in frail older people and to assess both oral health and swallowing problems among older people in short‐term care.

Dental Caries Experience and Oral Health Related Quality of Life in Working Adults

Objective

To evaluate effect of dental caries experience and untreated dental decay on Oral Health-Related Quality of Life (OHRQoL) in working adults.

Methods

The clinical records of 160 patients were reviewed. Dental health indicators were derived from individual tooth- and surface-level data allowing for calculating the number of decayed surfaces (D), number of decayed missed filled surfaces (DMFS), and significant caries (SiC) indices. A questionnaire was administered to verify demographic factors and OHRQoL. The questionnaire was administered via face-to-face interview, for patients in the hospital; or via telephone interview, for those who could not complete it during their hospital visit. Models were developed using multivariable linear regression to predict total OHIP-14 scores and examine the simultaneous association of independent and outcome variables. The model was adjusted for age, gender, and nationality..

Results

Physical limitation and psychological discomfort were the most frequent impacted domains, affecting 17.1% and 7.5% of subjects, respectively. Painful aching was the most frequent item to have any impact, affecting 64.4% of the subjects. The results of multivariable analysis indicated that the SiC score could statistically significantly predict the Oral Health Impact Profile (OHIP) score, P=0.0003. In the linear regression model, for participants with DMFS equal to or higher than the SiC, on average, OHIP scores were almost 10 points higher than for participants with DMFS below the SiC.

Conclusion

The more the dental decay the higher the impact on OHRQoL. From a dental public health perspective, using OHRQoL as a need assessment tool, along with dental clinical indicator, can be helpful in planning and targeting public health programs for the most in-need adult populations.

Clinical Significance

This study identified that patients with severe dental caries report poorer OHRQoL. Clinicians should be aware of impacts that dental decay may have on OHRQoL, including physical, psychological concerns, and pain.

Perceived oral health and its association with symptoms of psychological distress, oral status and socio-demographic characteristics among elderly in Norway

Background

There is poor knowledge about the extent to which psychological distress influences oral health in older people in Norway. The aim of this study was two-fold: i) to describe the oral health of Norwegian elderly and their levels of psychological distress; and ii) to examine the relationship of psychological distress with self-rated oral health, while controlling for oral status and socio-demographic characteristics, in Norwegian elderly.

Methods

Data were retrieved from a national cross-sectional survey conducted by Statistics Norway in 2012 and included information about self-rated oral health, psychological distress (measured using the Hopkins Symptom Checklist 25; HSCL-25), gender, age, civil status, smoking, self-reported number of teeth present and dental attendance for 949 non-institutionalised adults aged 65 years or older. Logistic regression was used to establish whether psychological distress predicts self-rated oral health, controlling for socio-demographic characteristics and oral status.

Results

Around 27% of the elderly reported having poor oral health, and 8 % had a HSCL-25 mean score ≥ 1.75, which indicates higher levels of psychological distress. Among the symptoms listed in the HSCL-25, the most frequently reported problems were lack of energy (1.7 ± 0.8) and difficulties falling and staying asleep (1.6 ± 0.7). The likelihood of reporting poor oral health was independently associated with having a mean HSCL-25 score ≥ 1.75 (OR = 1.89; 95% CI = 1.14–3.15), even when smoking (OR = 1.83; 95% CI = 1.17, 2.87) and having fewer than 20 teeth (OR = 3.49; 95% CI = 2.56, 4.76) were taken into account.

Conclusion

Most of the Norwegian elderly in our sample perceived themselves to have good oral health and reported relatively low levels of psychological distress. Higher levels of psychological distress can influence the oral health of the elderly independently of other factors such as smoking and having reduced number of teeth. Dental care professionals should consider screening their elderly patients for psychological distress and individualise the information about dental care for this specific population.

The Impact of Hyposalivation on Quality of Life (QoL) and Oral Health in the Aging Population of Al Madinah Al Munawarrah

Hyposalivation (HS) affects aging individuals by causing pain and discomfort in the oral cavity. The aim here was to determine the impact of hyposalivation and the saliva pH on the quality of life and caries status of geriatrics population. A total of 138 male outpatients attending the Taibah University College of Dentistry (TUCoD) dental clinic were included in the study. The saliva flow, pH, Quality of Life (QoL), and caries status were recorded. The QoL was measured using the Arabic version of the Oral Health Impact Profile-14 (OHIP-14), and the caries status was recorded using the Decayed, Missed, Filled Teeth (DMFT) index. The mean age was 67.5 years and 64% were classified as having hyposalivation. The older respondents tended to have a lower saliva flow and pH compared to their younger counterparts. There was a significant inverse association (p = 0.02) between the caries status and mean saliva flow rate. There was also a significant (p < 0.001) positive correlation between caries and the OHIP-14 scores (Spearman’s ρ = 0.293). The prevalence of hyposalivation was relatively high and there was an inverse relationship between the age, the saliva flow, and pH. Those with more caries reported significantly poor QoL.

Theory analysis of the Dental Hygiene Human Needs Conceptual Model

PURPOSE

Theories provide a structural knowing about concept relationships, practice intricacies, and intuitions and thus shape the distinct body of the profession. Capturing ways of knowing and being is essential to any professions' practice, education and research. This process defines the phenomenon of the profession - its existence or experience. Theory evaluation is a systematic criterion-based assessment of a specific theory. This study presents a theory analysis of the Dental Hygiene Human Needs Conceptual Model (DH HNCM).

METHODS

Using the Walker and Avant Theory Analysis, a seven-step process, the DH HNCM, was analysed and evaluated for its meaningfulness and contribution to dental hygiene. The steps include the following: (i) investigate the origins; (ii) examine relationships of the theory's concepts; (iii) assess the logic of the theory's structure; (iv) consider the usefulness to practice; (v) judge the generalizability; (vi) evaluate the parsimony; and (vii) appraise the testability of the theory.

FINDINGS

Human needs theory in nursing and Maslow's Hierarchy of Need Theory prompted this theory's development. The DH HNCM depicts four concepts based on the paradigm concepts of the profession: client, health/oral health, environment and dental hygiene actions, and includes validated eleven human needs that evolved overtime to eight. It is logical, simplistic, allows scientific predictions and testing, and provides a unique lens for the dental hygiene practitioner. With this model, dental hygienists have entered practice, knowing they enable clients to meet their human needs.

CONCLUSION

For the DH HNCM, theory analysis affirmed that the model is reasonable and insightful and adds to the dental hygiene professions' epistemology and ontology.

Oral health and quality of life in the municipal senior citizen's social clubs for people over 65 of Valencia, Spain

Background

The world population is aging considerably. The state of elderly´s dentition is poor. Many authors agree that the oral health status influence the elderly´s quality of life.The objective of our study was to analyze the relation between the oral health status and the general health status through the quality of life of elderly people aged 65 years or more in Valencia, Spain.

Material and Methods

A cross-sectional oral health survey and an oral examination have been designed to study an elderly population. Subjects: 202 adults (103 men and 99 women). Age: 65 years of age and over. Setting: Randomly selected senior citizen´s social clubs. The Oral Health Impact Profile (OHIP-14) has been used to obtain the oral health survey. Moreover, the EuroQol-5d and a Visual Analogue Scale (VAS) have been the tools to obtain the general health status. Finally, sociodemographic and oral health questions have been needed.

Results

Descriptive and inferential results have been done and the main results are the following, the mean additive score of the OHIP-14 was 8.88, the mean value of the EuroQol-5d was 0.58 and of the VAS, 72.90. The OHIP-14 was consistently and significantly correlated with the index EuroQol-5d and with variables such as number of teeth, missing teeth, DMFT, dental status (being or not edentulous) and occupation. The EuroQol-5d was related to dental habits, sex, income, systemic pathologies and filled teeth.

Conclusions

The oral health has a high impact on quality of life. The oral health and the general health are closely related. The oral hygiene and getting toothless influence negatively on the quality of life of elderly people.

Key words:Elderly, geriatric dentistry, oral health, oral hygiene, quality of life.

The Responsiveness of Patients' Quality of Life to Dental Caries Treatment-A Prospective Study

The objective of this study was to determine the responsiveness of oral health-related quality of life (OHRQoL) (oral health impact profile [OHIP] and oral impact on daily performance [OIDP]) and health-related quality of life (HRQoL) (World Health Organization quality of life scale, brief [WHOQOL-BREF]) in dental caries restoration treatment. The study also aimed to assess the influence of treatment on the responsiveness of patients' quality of life (QoL). A total of 126 patients (aged 16-40 years) received dental caries restoration treatment with a 2-week follow-up and pre- and posttreatment interviews by questionnaire. Patients were assessed for their perceptions of OHRQoL and HRQoL by using the OHIP, OIDP, and WHOQOL-BREF measures. The responsiveness of all outcome measurements was assessed by effect size (ES). Stepwise multiple regression analysis was used to examine the association with the responsiveness of all outcome measurements. Significant differences were found between OIDP (ES = 0.39), OHIP (ES = 0.54), and WHOQOL-BREF (ES = 0.13) with regard to pretreatment and posttreatment (p-values: <0.0001, <0.0001, and 0.0120, respectively). Sex and dental caries status at baseline were significantly associated with responsiveness by all measurements. This study suggests that dental caries treatment moderately improves OHRQoL, but is less related to HRQoL. Furthermore, the number of dental caries and restoration are important factors affecting the improvement of patients' perceived OHRQoL.

Correlation between upper limb function and oral health impact in stroke survivors

[Purpose] The aim of the present study was to evaluate the relationship between upper limb impairment and oral health impact in individuals with hemiparesis stemming from a stroke. [Subjects and Methods] The study subjects were conducted with a sample of 27 stroke survivors with complete or partial hemiparesis with brachial or crural predominance. The 14-item short version of the Oral Health Impact Profile was used to evaluate perceptions of oral health. The Brazilian version of the Stroke Specific Quality of Life Scale was used to evaluate perceptions regarding quality of life. [Results] A statistically significant association was found between the upper extremity function subscale of the SSQOL-Brazil and the impact of oral health evaluated using the OHIP-14, with a strong correlation found for the physical pain subscale, moderate correlations with the functional limitation, psychological discomfort, physical disability, social disability and social handicap subscales as well as a weak correlation with the psychological disability subscale. Analyzing the OHIP-14 scores with regard to the impact of oral health on quality of life, the most frequent classification was weak impact, with small rates of moderate and strong impact. [Conclusion] Compromised upper limb function and self-perceived poor oral health, whether due to cultural resignation or functional disability, exert a negative impact on the quality of life of individuals with hemiparesis stemming from a stroke.

Oral health-related quality-of-life and mental health in individuals with chronic obstructive pulmonary disease (COPD)

OBJECTIVES

To investigate the association between oral health, oral health-related quality-of-life (OHRQoL) and mental health-related quality-of-life (QoL) in persons with chronic obstructive pulmonary disease (COPD) with respect to demographic, social and clinical oral health variables.

MATERIALS AND METHODS

One hundred participants were included in a cross-sectional study at a hospital in Norway. Data were collected via the Oral Health Impact Profile (OHIP-14), the SF-36v2 Health Survey Mental Component (MCS), other self-reported factors, an interview and a clinical examination. Multiple regression analyses were performed. The Regional Committee for Medical and Health Research Ethics approved the study. RESULTS. Higher education (p < 0.01), being a smoker (p < 0.05) and experience of oral health problems (p < 0.001) were significantly associated with oral health-related quality-of-life (OHRQoL). Furthermore, those with feelings of dry mouth (p < 0.05) and impaired OHRQoL (p < 0.001) experienced more mental health problems.

CONCLUSIONS

This study demonstrated that oral health and personal factors are related to mental health-related QoL and OHRQoL in individuals with COPD. This finding shows the need to focus on oral care.

The impact of having natural teeth on the QoL of frail dentulous older people. A qualitative study

Background

In order to adapt oral care and treatment to the demands of the growing group of frail dentulous older people, it is important to understand how and to which extent having natural teeth contributes to the quality of life (QoL) of frail older people and how frailty influences their perspective.

Methods

A qualitative approach was used. Interviews with 38 Dutch frail older dentulous people were tape-recorded, transcribed, coded for content and analyzed. Additional information was collected which included age, gender, living situation, use of dental prostheses, self-reported oral health status, chronic disorders, and an index for frailty.

Results

Seven themes were identified in the relationship between natural teeth and the QoL of the participants: pride and achievement; intactness; sense of control; oral function; appearance; comfort; along with coping and adapting to disabilities. Having natural teeth generally had a positive effect on QoL. Positive effects through pride and achievement, intactness, and sense of control were most apparent for the most severely frail. They compared themselves with peers who are more often edentate, and valued the good state of their teeth against the background of their declining health, especially those with disabilities causing severe chronic pain or impaired fine-motor skills. The effect of coping with and adaptation to tooth loss was also most apparent for the most severely frail. There was a gender effect in that the men generally cared less about having natural teeth than women, regardless of their level of frailty.

Conclusions

QoL of frail older people is positively influenced by natural teeth, and this effect seems to increase with increasing frailty. Preservation of teeth contributes to a positive body image and self-worth. Oral care for frail people should aim to preserve natural teeth if possible.

Socioeconomic inequalities in dental services utilisation in a Norwegian county: The third Nord-Trøndelag Health Survey

Aim: To assess the level of socioeconomic inequity in dental care utilisation in Norway and enable comparison with recent international comparative studies. Methods: We studied dental care utilisation among 17,136 men and 21,414 women in the third Nord-Trøndelag Health Survey (2006–08). Respondents aged 20 years and above were included in the study, and analyses were also performed within subgroups of age and gender (20–39, 40–59, and ≥60 years). Income-related horizontal inequity was estimated by means of concentration indices. Education-related inequity was estimated as relative risks. Results: We found consistent pro-rich income inequity among men and women of all ages. The level of income inequity was highest among men and women ≥60 years, and in this group the income gradient was steepest between the poorest and the middle quintiles. Pro-educated inequity was found exclusively among men and women ≥60 years. General attendance was high (77%). Conclusion: The overall level of income-related inequity in dental services utilisation was low compared to other European countries as reported in two recent international studies of socioeconomic inequalities in dental care utilisation. Pro-rich and pro-educated inequity is a public health challenge mainly in the older part of the population.

Dental implants and improvement of oral health-related quality of life

OBJECTIVES

Oral health-related quality of life (OHRQoL) is a multifaceted field involving many factors. The aim of our study was to assess whether implant therapy improves OHRQoL in dental patients.

METHODS

Patients receiving at least one implant completed a health-related questionnaire before and after the implantation (minimum 1.5 months). Questions covered the functional and aesthetic scales (AS). Paired differences in individual scores were analysed using the Wilcoxon signed-rank test. A univariate analysis of covariance was used to relate overall and scale-specific average paired differences to age, gender, marital and educational status. Multivariate analysis of covariance was used to assess interactions between the covariates and different scales of outcome. All tests were performed at statistical significance level α = 0.05.

RESULTS

All twelve Wilcoxon tests supported an improvement in OHRQoL after implant placement. On the AS, the mean difference in OHRQoL scores was found to be associated with marital status, presence of aesthetic reasons for undergoing the surgery and number of front teeth replaced by implants. On the functional scale (FS), most significant associations were observed with the number of front teeth replaced via implantation, followed by the presence of chewing problems and marital status. The multivariate analysis helped to identify the covariates that varied significantly over the two scales of interest.

CONCLUSIONS

Effects of covariates responding significantly differently on different scales should not be summarized using an overall univariate analysis, using paired score differences averaged over all items. Such effect summary would be misleading. In the present study, significant implant-related improvements in OHRQoL were observed on both the aesthetic and FS in patients with at least one implant in the front dental area.

Oral health-related quality of life and oral status in a German working population

The study aim was to identify predictors of impaired oral health-related quality of life (OHRQoL). Employees of five companies were offered a clinical full-mouth examination. Oral health-related quality of life was measured with the German version of the Oral Health Impact Profile (OHIP) and summarized as additive scores (OHIP-ADD) and as prevalence of negative impacts (OHIP-SC). Two logistic regression models were developed for the odds of increased scores of the target variables OHIP-ADD and OHIP-SC. The target variables were dichotomized, and for the OHIP-ADD, the cut-off point for having impaired OHRQoL was heuristically defined as OHIP-ADD > 34. For the OHIP-SC, the corresponding threshold was OHIP-SC > 0. In the model for the OHIP-ADD, female gender, impaired aesthetics, few posterior occluding pairs, and painful masticatory muscles proved to be significant independent variables. For the OHIP-SC, female gender, impaired aesthetics, painful masticatory muscles, joint sounds, missing mandibular teeth, and carious teeth were significant. This cross-sectional study showed that within the models for both OHIP-ADD and OHIP-SC the high-risk person for impaired OHRQoL is a woman with impaired aesthetics and painful masticatory muscles.

Oral health-related quality of life and dental implants — preliminary study

Oral health-related quality of life (OHRQoL) is multifaceted and involves many factors. One of them is the use of dental implants. It was the aim of our study to assess whether implant therapy might improve OHRQoL. We consulted patients with at least one Astra Tech implant. Each patient completed oral health questionnaires, which were then statistically evaluated using the Wilcoxon signed-ranks test and Analysis of Covariance from a functional and aesthetic point of view. Differential response on individual scales was assessed using multivariate approach. All twelve marginal Wilcoxon tests showed an overall improvement in OHQoL (α = 0.05). On the aesthetic scale, OHRQoL was found to be associated with marital status, aesthetic reasons for undergoing surgery and number of front teeth replaced by implants. On the functional scale, three covariates were statistically significantly and appeared to have affected the levels of OHRQoL. The most significant explanatory effect was observed for the number of front teeth replaced via implantation, followed by the presence of chewing problems. Marital status was also found to have significantly affected the OHRQoL functional scale. Significant implant-related improvements in both scales were observed in patients with at least one implant in the front dental area.

What contributes to self-rated oral health among community-dwelling older adults? Findings from the ElderSmile program

OBJECTIVES

As part of ongoing efforts by the Columbia University College of Dental Medicine to devise community-based models of health promotion and care for local residents, we sought to answer the following query: "What contributes to self-rated oral health among community-dwelling older adults?"

METHODS

The present study is cross sectional in design and centrally concerned with baseline data collected during community-based screenings of adults aged 50 years and older who agreed to participate in the ElderSmile program in northern Manhattan, New York City. The primary outcome measure of interest is self-rated oral health, which was assessed as follows: "Overall, how would you rate the health of your teeth and gums - excellent, good, fair, or poor?"

RESULTS

More than a quarter (28.5 percent) of ElderSmile participants aged 50 years and older reported that their oral health was poor. After adjustment for age (in years), place of birth, educational level, and dental insurance status in a logistic regression model, recent visits to the dentist (within the past year versus more than a year ago) contributed to better self-rated oral health and non-Hispanic Black race/ethnicity, dentate (versus edentulous) status, tooth decay as measured by decayed missing filled teeth, and severe periodontal inflammation contributed to worse self-rated oral health in this population.

CONCLUSIONS

Recent dental care contributed to better self-rated oral health among community-dwelling older adults living in northern Manhattan. Significant gradients were evident in the caries experience and periodontal inflammation of dentate adults by self-rated oral health, suggesting that untreated oral disease contributes to poor self-rated oral health.

Does oral health matter in people's daily life? Oral health-related quality of life in adults 35-47 years of age in Norway

OBJECTIVE

The aim of this study was to assess the effect of oral health on aspects of daily life measured by the Dental Impact Profile (DIP) in 35- to 47-year-old individuals in Norway, and to study associations between reported effects and demographic variables, subjectively assessed oral health, general health, oral health behaviour and clinical oral health.

MATERIAL AND METHODS

A stratified randomized sample of 249 individuals received a questionnaire regarding demographic questions, dental visits, oral hygiene behaviour, self-rated oral health and general health and satisfaction with oral health. The DIP measured the effects of oral health on daily life. Teeth present and caries experience were registered by clinical examination. Bi- and multivariate analyses and factor analysis were used.

RESULTS

Items most frequently reported to be positively or negatively influenced by oral health were chewing and biting, eating, smiling and laughing, feeling comfortable and appearance. Only 1% reported no effects of oral health. Individuals with fewer than two decayed teeth, individuals who rated their oral health as good or practised good oral health habits reported more positive effects than others on oral quality of life (P ≤ 0.05). When the variables were included in multivariate analysis, none was statistically significant. The subscales of the DIP were somewhat different from the originally suggested subscales.

CONCLUSIONS

This study showed that most adults reported oral health to be important for masticatory functions and confirmed that oral health also had impacts on other aspects of life.
