Dental problems and chronic diseases in mentally ill homeless adults: a cross-sectional study.

BACKGROUND: Dental problems (DPs) and physical chronic diseases (CDs) are highly prevalent and incident in people with low socioeconomic status such as homeless individuals. Yet, evidence on the association between DPs and physical CDs in this population is limited. In the present study, we assessed the association between DPs and type and number of CDs in individuals experienced chronic homelessness and serious mental health problems. METHODS: We analyzed cross-sectional baseline data from 575 homeless adults with serious mental health problems participating in the Toronto site of the At Home/Chez Soi randomized controlled trial. Chronic DPs (lasting at least 6 months) were the primary exposure variable. Presence of self-reported CDs, including heart disease, effect of stroke, hypertension, diabetes, asthma, chronic bronchitis/emphysema, stomach or intestinal ulcer, inflammatory bowel disease, migraine, thyroid problems, arthritis, kidney/bladder problems, liver disease (other than hepatitis), and iron-deficiency anemia, were the primary outcomes. The total number of CDs was also analyzed as a secondary outcome. Logistic regression models were used to assess the association between DPs with each of the studied CDs, and negative binomial regression was used to test the association between DPs with the number of CDs. RESULTS: In our 575 homeless participants (68.5% males) with mean age 40.3 (11.8) years, a high proportion had DPs (42.5%). The presence of DPs was positively associated with heart disease (adjusted odds ratio (AOR):4.19,1.67-10.52), diabetes (AOR:2.17,1.13-4.17), chronic bronchitis (AOR:2.34,1.28-4.29), stomach or intestinal ulcer (AOR:3.48,1.80-6.73), inflammatory bowel disease (AOR:2.52,1.38-4.60), migraine (AOR:1.80,1.20-2.72), arthritis (AOR:2.71,1.71-4.29), kidney/bladder problems (AOR:2.43,1.30-4.54), and iron-deficiency anemia (AOR:3.28,1.90-5.65). DPs were also associated with a higher number of CDs (IRR: 1.62,1.38-1.90). CONCLUSION: Dental health problems in homeless individuals with serious mental disorders are associated with several CDs. Dental care should be better integrated into existing social and health programs serving this population to improve their overall health status. The AH/CS study is registered with the International Standard Randomized Control Trial Number Register (ISRCTN42520374).

Impact of Oral Health and Sociodemographic Factors on Quality of Life: A Cross-sectional Study.

Aim: The aim of this study was to determine the impact of oral health and socioeconomic variables on the quality of life in a sample of low-income Brazilians. Materials and methods: The sample consisted of 400 adults assisted by the Rescuing Smiles Social Program (Pernambuco University) in June 2014 in the town of Arcoverde, Pernambuco. Two 18+ physically and mentally healthy people were chosen to participate in the study per household. The data obtained were analyzed using Kruskal-Wallis and Mann-Whitney tests. Results: About 75% of participants were female, averaging 42.65 years; 59% had elementary schooling and 27% were illiterate; 63% of them needed dental restorative treatment, 59.5% periodontal, and 43.3% surgical procedures; and 68.2% of the respondents showed partial tooth loss, 22.8% were totally edentulous, and 9% had full dentition. Oral health impact profile (OHIP)-14 average score was 14.91, considered low. The highest averages were observed in low-income individuals (16.25). Individuals with total or partial tooth loss had an average 14.26 and 15.79, respectively, thus showing a statistically significant difference as compared with total dentate (9.86). Conclusion: Although low-income individuals with tooth loss showed the highest OHIP-14 averages, it could be concluded that oral condition did not affect the quality of life of most individuals in the population studied. Clinical significance: Thus, oral health did not have a significant impact on respondent health awareness. This study showed the need to better inform the public of the relevance of oral health to quality of life. Keywords: Oral health, Oral health impact profile-14, Quality of life.

Dental knowledge and dental service utilization: A 2-year follow-up study.

OBJECTIVES: To investigate associations of dental knowledge with dental service utilization over 2 years in South Australians aged 45-54 years. METHODS: In 2004-2005, a random sample of 2469 adults aged 45-54 years from Adelaide, South Australia, who were selected from the Australian electoral roll was surveyed. The outcome variables were the numbers of visits and dental services received over 2 years. Data were analysed using log-binomial and Poisson regression. Statistical significance was determined at P < .05. RESULTS: The response rates were 43.8% in the study group (n = 879) and 50.7% in the comparison group (n = 107). Oral examinations were conducted on 709 persons (81% of study group participants). Dental services data were collected from approximately 60% of participants at the end of years 1 and 2. After adjusting for sex, education, health card status, toothbrushing and inadequate dentition, higher caries knowledge and periodontal knowledge scores were associated with higher percentages of persons making dental visits (prevalence ratio, 95% CI: 1.2, 1.1-1.3 and 1.1, 1.0-1.3), and lower rates of extraction (rate ratio, 95% CI: 0.2, 0.1-0.4 and 0.4, 0.3-0.7) and endodontic services (0.5, 0.3-0.9 and 0.5, 0.3-0.7). Higher caries knowledge was associated with lower rates of fillings (0.8, 0.7-0.9) and denture services (0.1, 0.0-0.6), while higher periodontal knowledge was associated with higher numbers of visits (1.3, 1.2-1.5), and prophylaxis services (1.4, 1.1-1.8) and crowns (1.7, 1.1-2.5). CONCLUSION: South Australians aged 45-54 years with higher dental knowledge had lower rates of invasive treatment over 2 years. These findings warrant policy initiatives that highlight the importance of dental knowledge in improving oral health.

Socioeconomic inequalities in dental health among middle-aged adults and the role of behavioral and psychosocial factors: evidence from the Spanish National Health Survey.

BACKGROUND: The goal of this analysis was to describe socioeconomic inequalities in dental health among Spanish middle-aged adults, and the role of behavioral and psychosocial factors in explaining these inequalities. METHODS: This cross-sectional study used survey data from the 2006 Spanish National Health Survey and focused on adults ages 30 - 64. The outcome was dental health status based on the presence of self-reported dental problems. We used education, income, and occupational class as indicators of socioeconomic position and applied logistic regression analysis to estimate associations. We included behavioral and psychosocial variables in the models and compared non-adjusted to adjusted estimates to assess their potential role in explaining socioeconomic gradients. RESULTS: Results showed clear socioeconomic gradients in dental health among middle-aged adults. The percentage of people who reported more dental problems increased among those with lower levels of education, income, and occupation. These gradients were statistically significant (p < .001). Logistic regression showed that groups with lower education, income, and occupation had higher odds of reporting the outcome (p < .001). Associations were stronger when considering education as the indicator of socioeconomic position. Substantial unexplained associations remained significant after adjusting the model by behavioral and psychosocial variables. CONCLUSIONS: This study shows significant socioeconomic gradients in dental health among middle-aged adults in Spain. Behavioral and psychosocial variables were insufficient to explain the inequalities described, suggesting the intervention of other factors. Further research should incorporate additional explanations to better understand and comprehensively address socioeconomic inequalities in dental health.

The Head and Neck Cancer Patient Concern Inventory© : Patient Concerns' Prevalence, Dental Concerns' Impact, and Relationships of Concerns with Quality of Life Measures.

PURPOSE: The Patient Concern Inventory© (PCI) is a clinical tool of self-reported patient concerns to be used by the clinician to structure the patient-oncologist visit. It was developed in the United Kingdom to address the issues of quality of life (QOL) in head and neck cancer (HNC) patients. The purpose of the study reported here was to determine the prevalence of PCI© items, the associations between PCI© items and QOL, and to explore the importance of oral/dental issues in the patient's well-being. METHODS: The PCI© and the University of Washington (UW-QOLv4) instruments were self-administered by an HNC population in a cross-sectional study. Following an a priori sample size estimate, consecutive HNC patients attending at the University of Florida's Oral Medicine and the ENT Clinics had the study described, eligibility assessed, and if eligible, were invited to participate in the study. Participants completed the PCI© and UW-QOL. PCI© issues prevalence was determined, and for those with a ≥10% prevalence: 1) Fisher's exact test was used to test for statistical differences between treatments, and 2) multivariable regression was used to test each of the prevalent PCI© issues across four QOL measures, health in the last 7 days, overall QOL in the last 7 days, and the physical and social domain scores. RESULTS: Twenty of 45 PCI© issues had a prevalence ≥10%. Of the 15 prevalent items statistically associated with a QOL measure, four issues are the clinical responsibility of the dental profession: 1) chewing/eating, 2) dental health/teeth, 3) mouth opening, and 4) salivation. An additional four (eight total, 50%) are of clinical concern for dental clinicians: 5) pain in head/neck, 6) swallowing, 7) speech/voice/being understood, and 8) taste. CONCLUSIONS: Dental concerns represent almost half of all PCI© concerns observed in 10% or more of the sample patients. Prosthodontists should support our maxillofacial prosthodontics specialists in joining other oral oncologists and advocate for comprehensive, integrated dental support for HNC patients by assuring dental involvement/inclusion with the multidisciplinary oncology team and a research agenda to established best patient-centered outcomes.

The functionality of masticatory apparatus and the sense of depression in patients over 55 years of age living in a family environment and social care centres. / Funkcjonalnosc narzadu zucia a poczucie depresji u pacjentów po 55. roku zycia zamieszkalych w srodowisku rodzinnym i w domach pomocy spolecznej.

OBJECTIVES: The aim of this study was to determine the relationship between the masticatory apparatus functionality and a sense of depression in patients over 55 years of age living in a family environment and the Social Care Centres (SCC). METHODS: Shortened version of the Geriatric Depression Scale (GDS) was used to assess the wellbeing of patients and their state/sense of depression. The clinical evaluation of masticatory function was performed during one appointment in the natural light. The clinical criterion for the retention of masticatory function, adopted by the World Health Organization was a contact between at least 20 opposing teeth, natural or artificial. RESULTS: Among patients with a low number of GDS points (0-5), statistically significantly higher proportion of people living in family houses (69.4%) maintained functionality of masticatory apparatus than of people living in SCC (23.5%). In contrast, among patients with a higher number of GDS points (6-15), statistically significantly higher proportion of patients living in SCC (70.8%) did not maintain functionality of masticatory apparatus than of those living in family houses (41.7%). CONCLUSIONS: Patients with a sense of depression living in Social Care Centres were more likely to report lack of functionality of masticatory apparatus than patients with a sense of depression living in family houses. The presence of a growing sense of depression significantly affected a lower rate of preserved functionality of masticatory apparatus or vice versa.

Pilot Study on the Influence of Nutritional Counselling and Implant Therapy on the Nutritional Status in Dentally Compromised Patients.

OBJECTIVES: To investigate the impact of implant-prosthetic rehabilitation combined with nutritional counseling on the nutritional status of patients with severely reduced dentitions. DESIGN: An explorative intervention study including an intra-individual comparison of 20 patients with severely reduced dentitions in terms of nutrition- and quality of life-related parameters recorded at baseline and at six and twelve months after implant-prosthetic rehabilitation. PARTICIPANTS: Twenty patients from the Department of Prosthetic Dentistry of Justus-Liebig University of Giessen, with an mean age of 63 years, who had fewer than ten pairs of antagonists. MEASUREMENTS: The baseline data collection included dental status, a chewing ability test, laboratory parameters, anthropometric data (body mass index), energy supply, a 3-day dietary record, an analysis of the oral health-related quality of life (OHRQoL) with the OHIP-G14, the Mini-Mental Status (MMS) and Mini Nutritional Assessment (MNA). Six months after implantation and prosthetic rehabilitation, individual nutritional counseling was performed by a dietician. Data were again collected and analyzed. A final follow-up was conducted 12 months after prosthetic rehabilitation. RESULTS: Despite the highly significant improvement in masticatory ability and OHRQoL after implant-prosthetic rehabilitation, no significant changes were observed regarding MNA, anthropometric data or energy supply. Except for cholinesterase (p = 0.012), ferritin (p = 0.003), folic acid (p = 0.019) and vitamin A (p = 0.004), no laboratory parameter changed significantly during the investigation period. In addition, no general significant differences were observed for nutrient intake or food choice. CONCLUSION: The present study does not confirm the assumption that the implant-prosthetic rehabilitation of patients with severely reduced residual dentitions with or without an individual nutritional counseling influences nutritional status.

Clinical leadership and prevention in practice: is a needs led preventive approach to the delivery of care to improve quality, outcomes and value in primary dental care practice a realistic concept?

BACKGROUND: There is a need to improve access to, and the quality of, service delivery in NHS primary dental care. Building public health thinking and leadership capacity in clinicians from primary care teams was seen as an underpinning component to achieving this goal. Clinical teams contributed to service redesign concepts and were contractually supported to embrace a preventive approach. METHODS: Improvement in quality and preventive focus of dental practice care delivery was explored through determining the impact of several projects, to share how evidence, skill mix and clinical leadership could be utilised in design, implementation and measurement of care outcomes in general dental practice in order to champion and advocate change, during a period of substantial change within the NHS system. The projects were: 1. A needs-led, evidence informed preventive care pathway approach to primary dental care delivery with a focus on quality and outcomes. 2. Building clinical leadership to influence and advocate for improved quality of care; and spread of learning through local professional networks. This comprised two separate projects: improved access for very young children called "Baby Teeth DO Matter" and the production of a clinically led, evidence-based guidance for periodontyal treatment in primary care called "Healthy Gums DO Matter". RESULTS: What worked and what hindered progress, is described. The projects developed understanding of how working with 'local majorities' of clinicians influenced, adoption and spread of learning, and the impact in prompting wider policy and contract reform in England. CONCLUSIONS: The projects identified issues that required change to meet population need. Clinicians were allowed to innovate in an environment working together with commissioners, patients and public health colleagues. Communication and the development of clinical leadership led to the development of an infrastructure to define care pathways and decision points in the patient's journey.

Evaluation of the saliva cortisol levels in patients under prosthetic treatment due to functional disorders of the masticatory organ.

One of the main etiological factors of the stomatognathic system dysfunction is stress and psychoemotional disorders. During stressful situations, there is an increase in the level of cortisol, the so-called stress hormone. Literature data indicate the existence of a correlation between blood cortisol levels and its amount in the saliva. This spurred an inspiration to undertake open, non-randomised studies, the objective of which was to conduct a comparative assessment of the saliva cortisol levels in patients with functional disorders of the masticatory system and in healthy volunteers, as well as to compare the results of cortisol levels with the results of survey-based tests with the use of Endler and Parker's CISS survey. Cortisol level was assessed due to its association with stress present in the body as one of the primary etiological factors of the stomatognathic system dysfunction, and hence the association of elevated cortisol levels assessed in the morning with the occurrence of dysfunctions of the stomatognathic system. The subject of the study is a group of 30 patients, of both sexes, aged between 20 and 46, who reported to the Dental Prosthetic Out-Patient Clinic of the Institute of Dentistry, Jagiellonian University in Cracow, for prosthetic treatment due to the painful form of functional masticatory organ disorders. The control group consisted of 30 subjects, aged between 19 and 41, in whom dysfunctions of the stomatognathic system were excluded. Collection of saliva for testing was performed at a fixed hour (9 am) into plastic test tubes with a stopper. Immediately after collection, the saliva was frozen at the temperature of -18 °C. The assessment of the cortisol levels was conducted by the high performance liquid chromatography (HPLC) with UV detection at the Department of Analytical Chemistry, Faculty of Pharmacy, Department of Laboratory Medicine of the Gdansk Medical University. Moreover, a 20-minute psychological test was conducted with the use of the CISS (coping inventory for stressful situations) survey in order to assess the patients in terms of their abilities to cope with stressful situations. The results obtained were submitted to a statistical analysis based on the conventional calculation procedures. The test group revealed significantly higher cortisol levels compared with the results obtained by the control group. The findings of the CISS survey confirmed the predominance of the emotion-focused strategy of coping with stressful situations in the test group. The results support the view that the psychoemotional factor is, to a considerable extent, conducive to the development of functional disorders. The elevated cortisol levels in patients with psychological disorders concur with the findings by other authors. The results obtained confirm that psychoemotional disorders may be one of the etiological factors of the stomatognathic system dysfunctions. The CISS survey, which was not used in similar studies before, makes it possible to obtain information on the subject's method of coping with stress, thus allowing for the initiation of a relevant psychological therapy aiding the prosthetic treatment.

The Parental Dental Concerns Scale (PDCS): its development and initial psychometric properties.

OBJECTIVES: To assess the validity and reliability of a Parental Dental Concerns Scale (PDCS) to identify parents unable to access preventive dental care for their children. METHODS: Two studies were conducted. In Study One, a purposive convenience sample of 399 Scottish parents answered questions on going to the dentist, family life and demographics. Parents were retested eight weeks later. In Study Two, 574 Scottish parents participating in a preventive oral health programme were posted the same questionnaire. Information on child dental attendance was gained from dental records. Data were analysed using exploratory (EFA) and confirmatory (CFA) factor analysis. Internal consistency and test-retest correlations provided reliability estimates. Validity was assessed with confirmatory factor analysis, correlations and independent t-tests. RESULTS: EFA indicated that the PDCS had a four factor structure, supported by a subsequent CFA. The PDCS and its four subscales had good internal consistency, concurrent validity and test-retest reliability. Further work is required to confirm the scale's predictive validity in discriminating between children and parents who did and did not attend the dental practice. CONCLUSIONS: The PDCS is a reliable scale, which demonstrates good construct validity. Further testing is required to confirm its predictive validity.

The EORTC QLQ-OH17: a supplementary module to the EORTC QLQ-C30 for assessment of oral health and quality of life in cancer patients.

AIMS: Assessment of oral and dental problems is seldom routine in clinical oncology, despite the potential negative impact of these problems on nutritional status, social function and quality of life (QoL). The aim was to develop a supplementary module to the European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30) focusing on oral health and related QoL issues in all cancer diagnoses. METHODS: The module development followed the EORTC guidelines. Phases 1&2 were conducted in France, Germany, Greece, Netherlands, Norway and United Kingdom, while seven countries representing seven languages were included in Phase 3. RESULTS: Eighty-five QoL-items were identified from systematic literature searches. Semi-structured interviews with health-care professionals experienced in oncology and oral/dental care (n=18) and patients (n=133) resulted in a provisional module with 41 items. In phase 3 this was further tested in 178 European patients representing different phases of disease and treatment. Results from the interviews, clinical experiences and statistical analyses resulted in the EORTC QLQ-OH17. The module consists of 17 items conceptualised into four multi-item scales (pain/discomfort, xerostomia, eating, information) and three single items related to use of dentures and future worries. CONCLUSION: This study provides a useful tool intended for use in conjunction with the EORTC QLQ-C30 for assessment of oral and dental problems. The increased awareness may lead to proper interventions, thereby preventing more serious problems and negative impact on QoL. The reliability and validity, the cross-cultural applicability and the psychometric properties of the module will be tested in a larger international study.

Oral health and social and emotional well-being in a birth cohort of Aboriginal Australian young adults.

BACKGROUND: Social and emotional well-being is an important component of overall health. In the Indigenous Australian context, risk indicators of poor social and emotional well-being include social determinants such as poor education, employment, income and housing as well as substance use, racial discrimination and cultural knowledge. This study sought to investigate associations between oral health-related factors and social and emotional well-being in a birth cohort of young Aboriginal adults residing in the northern region of Australia's Northern Territory. METHODS: Data were collected on five validated domains of social and emotional well-being: anxiety, resilience, depression, suicide and overall mental health. Independent variables included socio-demographics, dental health behaviour, dental disease experience, oral health-related quality of life, substance use, racial discrimination and cultural knowledge. RESULTS: After adjusting for other covariates, poor oral health-related items were associated with each of the social and emotional well-being domains. Specifically, anxiety was associated with being female, having one or more decayed teeth and racial discrimination. Resilience was associated with being male, having a job, owning a toothbrush, having one or more filled teeth and knowing a lot about Indigenous culture; while being female, having experienced dental pain in the past year, use of alcohol, use of marijuana and racial discrimination were associated with depression. Suicide was associated with being female, having experience of untreated dental decay and racial discrimination; while being female, having experience of dental disease in one or more teeth, being dissatisfied about dental appearance and racial discrimination were associated with poor mental health. CONCLUSION: The results suggest there may be value in including oral health-related initiatives when exploring the role of physical conditions on Indigenous social and emotional well-being.

[Results of dental implantation in elderly patients].

In absence of contraindications, with competent planning and complex oral mouth treatment and adequate use of surgical and orthopedic protocols, the dental implantation could be successfully implemented for esthetical and functional rehabilitation of elderly patients with different forms of adentia. Dental implantation can significantly increase the quality of life of elderly patients.

Association between dietary quality of rural older adults and self-reported food avoidance and food modification due to oral health problems.

OBJECTIVES: To quantify the association between food avoidance and modification due to oral health problems, to examine the association between food practices and dietary quality, and to determine foods associated with these self-management behaviors. DESIGN: Cross-sectional. SETTING: Rural North Carolina. PARTICIPANTS: Six hundred thirty-five community-dwelling adults aged 60 and older. MEASUREMENTS: Demographic and food frequency data and oral health assessments were obtained during home visits. Avoidance (0, 1-2 foods, 3-14 foods) and modification (0-3 foods, 4-5 foods) due to oral health problems were assessed for foods representing oral health challenges. Food frequency data were converted into Healthy Eating Index-2005 (HEI-2005) scores. Linear regression models tested the significance of associations between HEI-2005 measures and food avoidance and modification. RESULTS: Thirty-five percent of participants avoided three to 14 foods, and 28% modified four to five foods. After adjusting for age, sex, ethnicity, poverty, education, and tooth loss, total HEI-2005 score was lower (P<.001) for persons avoiding more foods and higher for persons modifying more foods (P<.001). Those avoiding three to 14 foods consumed more saturated fat and energy from solid fat and added sugar and less nonhydrogenated fat than those avoiding fewer than three foods. Those who modified four to five foods consumed less saturated fat and solid fat and added sugar but more total grains than those modifying fewer than four foods. CONCLUSION: Food avoidance and modification due to oral health problems are associated with significant differences in dietary quality. Approaches to minimize food avoidance and promote food modification by persons having eating difficulties due to oral health conditions are needed.

Oral health-related quality of life and dental status in an outpatient psychiatric population: a multivariate approach.

Research related to oral health in people with mental health problems may deepen our understanding of the quality of life of such individuals. This study aimed to investigate the relationship between oral status, health perceptions and life satisfaction, and their impacts on oral health-related quality of life (OHQoL). Data were collected from 113 patients in outpatient psychiatric care using a structured interview and an oral examination. Six multivariate models (one comprising the total population, three separate diagnostic groups, and two sex groups) investigated the variance in OHQoL. In the total population, the number of teeth, subjective life satisfaction, perception of physical health, sex, and relying on chance accounted for 40% of the variance. In the group consisting of patients diagnosed with schizophrenia 41% of the variance was explained by the variables 'number of teeth' and 'perception of physical health'. In the group diagnosed with mood disorders, the variable 'number of teeth' accounted for 58% of the variance. The variance in the remaining group of diagnoses was explained, up to 38%, by life satisfaction and reliance on chance. The sex models revealed significant differences: men considered the responsibility of caring for their oral health as a health matter, while women saw oral health as a more subjective issue. The perception of OHQoL was found to be dependent on the particular psychiatric diagnosis and sex. Such findings can be of use in the development of rehabilitation, as well as preventive strategies that could be individually tailored to maintain OHQoL and oral health.

[Effect of dental status on the quality of life in elderly patients].

The article deals with the quality of life in old and very old persons in terms of their dental status. Oral mucous coat status is an important criterion in the evaluation of the status of other organism tissues, including dental and maxillary system tissues, and exerts a significant effect on the quality of life in old and very old persons.

Is the oral health impact profile measuring up? Investigating the scale's construct validity using structural equation modelling.

OBJECTIVES: The aim of the study was to provide an empirical test of the construct validity of the Oral Health Impact Profile as a measure of Locker's conceptual model of oral health. METHODS: A secondary analysis of data from the Ontario Study of Older Adults was carried out using structural equation modelling to assess the degree to which scale items measured the construct they were supposed to measure (within-construct validity) and whether relations between constructs were as hypothesized by Locker's model (between-construct validity). RESULTS: The findings indicated that the Oral Health Impact Profile as currently conceived does not have adequate within-construct validity. Scale items did not always measure the construct they were supposed to measure, some items within a construct were redundant, many measured more than one construct, and the scale did not represent seven separate constructs of oral health as originally devised. Following reconceptualization of the scale, the revised six-factor 22 item version was a better fit to the data. However, the scale did not have adequate between-construct validity. CONCLUSION: The present findings do not provide support for the conceptual basis of the Oral Health Impact Profile as a measure of Locker's model of oral health. The need for further conceptual development of the scale, and Locker's model, are discussed.

Oral health-related quality of life in children: part II. Effects of clinical oral health status. A systematic review.

OBJECTIVE: Children are affected by numerous oral and orofacial disorders, which have the potential to compromise functioning, well-being and the quality of life (QoL). The purpose of this paper was to review the literature about children's clinical oral health status and health-related quality of life (HRQoL) and to assess the respective association. MATERIALS AND METHODS: The authors searched Medline, ISI, Lilacs and Scielo for articles from 1985 to 2007. The inclusion criteria were randomized, cross-sectional, longitudinal or retrospective studies that used well-validated oral health-related QoL instruments, children self-applied questionnaires and quantitative measurements of clinical oral health status. RESULTS: Of the 402 articles that were critically assessed, 12 studies were included in the critical appraisal of the project. CONCLUSIONS: There is a relationship between clinical oral health status and HRQoL in children. In the studies that suggested weak relationships between children's oral conditions and HRQoL, the explanations were low disease levels in the sample, the conditions under investigation may have caused immeasurably low levels of impact or the impacts were mediated by inter- and intravariables according to culture and education. Moreover, relationships between biological or clinical variables and HRQoL outcomes are not direct, but mediated by a variety or personal, social and environmental variables, as well as by the child development, which have influence on the comprehension about the relationship among health, illness and QoL. So, longitudinal studies are necessary to determine validity, responsiveness and minimal clinically important difference.
