Social inequalities in oral health and in use of oral health care services among adolescents in Uganda.

The aim of this study was to describe clinical and self-perceived indicators of oral health status and the use of oral health care services by social and demographic characteristics. In 2001, a cross-sectional random sample survey was conducted in urban and rural settings in Uganda (Kampala and Lira, respectively), and 1146 secondary school students with a mean age of 15.8 years completed questionnaires in school. Dental caries was recorded by one examiner on a random subsample of 372 students. Logistic regression analyses revealed that being an urban resident was associated with higher odds for having dental caries (dmft > 0), seeking care because of toothache (delayed treatment demand) and being dissatisfied with one's own oral health status [adjusted odds ratio (OR) = 1.5-2.1]. Being an urban resident was associated with lower odds for oral health care attendance generally and for having missing teeth in particular (adjusted OR = 0.6-0.4). Students who had parents with a higher education and those with weak social ties were, respectively, less and more likely to be dissatisfied with their oral health status. As compared to caries-free participants, the odds for being dissatisfied with oral health and delayed treatment demand increased significantly with an increasing dmft score (adjusted OR = 2.1-3.2). Urban students were most likely to have a dmft > 0 and to rate their oral health status negatively. Having received dental care and the prevalence of missing teeth, and delayed treatment demand were, respectively, most and least prevalent among rural students. Dental caries at different diagnostic cut-off points and weak social ties affected self-reported oral health negatively, independently of social and demographic characteristics.

Validity and reliability of the Oral Impacts on Daily Performance (OIDP) frequency scale: a cross-sectional study of adolescents in Uganda.

BackgroundAssessing oral health related quality of life impact of mouth in adolescents is a relatively ignored area in dental research. This study aimed to examine reliability and validity of an abbreviated version of the oral impact of daily performance (OIDP) questionnaire and to analyse the interrelationship among OIDP scores, socio-demographic characteristics and oral health status in Uganda.Method1146 adolescents (mean age 15.8, response rate 87%) attending secondary schools in Kampala (urban) and Lira (rural) completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. A clinical examination was conducted among 372 students (mean age 16.3, response rate 72%) and caries was assessed following the World Health Organisation criteria (1997).Results62% of the students experienced at least one oral impact during the 6 months preceding the survey. Cronbach's alpha for the OIDP frequency items was 0.91 and the corrected item-total correlation ranged from 0.62 to 0.75. Discriminant and construct validity were demonstrated in that the OIDP scores varied systematically in the expected direction with missing teeth and self-report indicators of oral health status, respectively. Socio-demographics and dental attendance did not predict OIDP through interaction with clinical indicators but varied systematically and independently with OIDP frequency scores in the multivariate analysis.Conclusionthe OIDP frequency score have acceptable psychometric properties in the context of an oral health survey among Ugandan adolescents. Some evidence of the importance of social and personal characteristics in shaping adolescents' responses to oral disorders was provided.

The self-assessed oral health status of individuals from White, Indian, Chinese and Black Caribbean communities in South-east England.

To determine the level of self-assessed oral symptoms and the impact of such symptoms among individuals from four ethnic groups resident in South-east England and the relationship between self-assessed oral health status, age, gender, employment status, educational level and ethnicity. Cross-sectional survey of a convenience sample of 366 individuals drawn from four ethnic groups. Subjective Oral Health Status Indicators (SOHSI). Individuals were recruited through community groups. All participants self-classified their ethnicity. Only completed questionnaires from participants categorising themselves as White, Black Caribbean, Chinese or Indian were included in the data analysis. Univariate statistical analysis revealed significant differences between ethnic groups in all but one of the SOHSI scales. Age and ethnicity (in particular membership of the Chinese community) emerged as significant predictors of SOHSI scale scores. Within the limitations imposed by convenience sampling, it has been found that differences exist among four ethnic groups in the UK in their reporting of self-assessed oral health status. Ethnicity and age, in particular, predict the reporting of self-assessed oral symptoms and the impact of such symptoms.

Applicability of an abbreviated version of the oral impacts on daily performances (OIDP) scale for use among Tanzanian students.

The objective was to examine the applicability of an abbreviated version of the oral impact of daily performances (OIDP) inventory to Tanzanian adults attending the University of Dar es Salaam. A total of 1123 students (mean age 26.4 years, response rate 58%) completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. After a period of 4 weeks, 228 students (mean age 24.6 years, response rate 65%) were examined clinically for the presence or absence of oral disorders. A total of 51% of the participants reported that an oral problem had affected them on at least one daily performance in the 6 months preceding the survey. Cronbach's alpha for the OIDP frequency items was 0.83 and 0.87 on the first and second administration of the questionnaire. A reliability coefficient (Spearman's rho) of 0.87 was obtained for the OIDP frequency scores. For five of the eight OIDP frequency items, the kappa values ranged from 0.60 to 1.0, whereas one scale item had the less satisfactory value of 0.22. Construct validity was demonstrated in that the OIDP frequency scores were statistically significantly associated in the expected direction with clinically observed oral problems and a global self-report indicator of oral health status, respectively. The OIDP frequency scale seems to have acceptable psychometric properties in the context of a descriptive questionnaire survey among Tanzanian university students.

Oral health status of rural adults in the United States

Many sociodemographic indicators of oral health disparity in the United States have been documented. Rural residence, however, has not been researched thoroughly, though it has been considered to be a potential indicator of disparity. The authors conducted this study to present information on the effects of rural residence on oral health in the United States. The authors conducted their analyses using data from adults aged 18 to 64 years from the 1995, 1997 and 1998 National Health Interview Surveys and the Third National Health and Nutritional Examination Survey, 1988-94. The authors present national estimates for various oral health status indicators including dental insurance coverage, unmet care needs, frequency of dental visits, caries experience and prevalence of edentulism by rural/urban residence. The authors found that adults living in rural areas were more likely to report having unmet dental care needs and were less likely to have had a dental visit in the past year compared with adults living in urban areas. The prevalence of edentulism among rural adults was 16.3 percent-almost twice that of urban adults. Caries experience also was more likely to be greater among adults residing in rural areas. Oral health disparities exist among U.S. adults living in rural and urban areas. Compared with urban residents, rural residents were less likely to report a dental visit in the past year and were more likely to be edentulous. By understanding the rural/urban differences in adult oral health status, practitioners, policy-makers and rural health advocates will have better information to use to promote activities that better meet the needs of rural adults in the United States.

The impact of attendance patterns on oral health in a general dental practice.

The aim of this study was to examine the impact of attendance patterns on oral health in the context of government policy on dental care and registration in the UK. The data involved 643 consecutive patient responses to a questionnaire on dental health taken from a survey that was conducted during 1998 in an urban area of Swansea. The survey continued for a period of six months and covered patients of 18 years of age and over, responding to a questionnaire on the subjective oral health status indicators including the pattern of their attendance to dental practices. Regular dental care attendance has a significant positive impact on dental health while its impact on the number of teeth present is insignificant. Regular attendees also suffer significantly less from the severity, prevalence, social and psychological impacts of dental health problems. Regular dental attendance is associated with better oral health when regularity of care is defined as a visit within a two-year period. The rationality of a 15 month registration period is therefore debatable in the context of developing equitable services.

Do regular attenders have better oral health?

Oral ill-health and deprivation among patients of a general dental practice in South Wales.

This study aims to establish and report on whether individuals from deprived areas suffer more ill health than adults from areas considered not to be deprived when visiting a general dental practice. Between December 1998 and June 1999 registered dental patients over 18 years of age attending for routine care completed a questionnaire measuring functional, experiential and psychosocial impact of oral ill health. In addition the clinical impact of ill health was established from the patient examination and record card. Clinical outcome was assessed by numbers of standing teeth, oral health was assessed using the Subjective Oral Health Status Indicators (SOHSI). The patient's postcode was used to categorise individuals from areas of different deprivation states. 99% were dentate with 88.4% having more than 20 teeth. A total of 71.8% were able to eat satisfactorily, 88.2% were able to speak satisfactorily, 54.6% were discontent, 99.4% were worried about their oral health and appearance, 62.8% were satisfied with their oral health, 44.8% experienced discomfort, 65.8% experienced other symptoms, and 86.8% experienced 'general well-being'. No differences were observed for clinical measures between the deprived groups. Only three out of eight oral health measures showed any differences between the deprived groups, namely, ability to speak, discontent and general well-being. More individuals from deprived areas experienced these impacts. It was anticipated that individuals from deprived areas would experience greater ill-health: this outcome was not as marked as expected.

Perceptions of the natural dentition in the context of multiple variables.

Perceived oral health status has been shown to be associated with a variety of single clinical and self-reported indicators of oral health and oral health-related behaviors. A behavioral model is utilized which hypothesizes that perceived condition of natural teeth is predicted by multiple factors, including individual demographic and enabling characteristics, other health perceptions and orientations, actual levels of diseases and conditions, and self-defined need for treatment. The data are from the clinical examination and adult questionnaire of Phase 1 (1988-1991) of the Third National Health and Nutrition Examination Survey, which is based on a stratified multistage probability sample to produce nationally representative data for the civilian, non-institutionalized US population. Multivariate hierarchical regressions were used to assess perceived condition of natural teeth in two groups of dentate adults (those with a dental visit during the past 12 months, and those with a less recent dental visit). Self-defined treatment need made a significant, non-trivial contribution after other variables had been controlled. In both subpopulation models, the perception of general health and epidemiological indicators of oral health status were also significant factors. Socio-economic indicators did not contribute significantly in either regression. Understanding components of overall perceptions of oral health moves us closer to understanding oral health behaviors and oral-health-related quality of life.

Three-year changes in self-perceived oral health status in an older Canadian population.

Although change is a central goal of oral health care interventions, little attention has yet been paid to change in self-perceptions of oral health status. This is an important omission, given the current emphasis on assessing health outcomes. This paper reports the results of a study which examined changes over a period of three years in self-perceived oral health among 611 community-dwelling Canadians aged 50 years and over. Change in self-perceptions was measured by means of a global transition item and change scores derived from repeat administrations of four subjective oral health status indicators. Overall, 20.5% reported that their oral health had deteriorated over the three-year observation period, 68.5% that it had remained the same, and 10.5% that it had improved. There was a significant association between these global change categories and change scores for the four subjective indicators. Because of the small number of edentulous subjects, the analysis of baseline characteristics predicting change was confined to dentate subjects. Bivariate and logistic regression analyses were used to compare the two groups reporting change with those whose oral health status remained stable over the observation period. The results suggest that, when compared with this reference group, those who deteriorated and those who improved were similar in some respects but distinct in others. Those who improved appeared to have specific oral conditions at baseline causing pain. Those who deteriorated had poor oral health in general and came from more disadvantaged backgrounds. However, the explanatory power of logistic regression models predicting change in self-perceived oral health was poor when judged in terms of model sensitivities. This was to be expected, given that the models did not include variables documenting the incidence of disease, receipt of dental care, or changes in social and personal circumstances over the observation period.

Clinical correlates of changes in self-perceived oral health in older adults.

Although numerous investigators have reported on self-perceived oral health status in adult and older adult populations, few have examined how these perceptions change over time. This paper uses data from a longitudinal oral health survey of community-dwelling Canadians aged 50 years and over to explore this issue. Data were collected at baseline and after 3 years. Change was assessed using a global transition judgement and change scores on four subjective oral health status indicators. These indicators addressed chewing capacity, oral and facial pain symptoms, other oral symptoms, and the psychosocial impact of oral disorders. Overall, 23.0% reported that their oral health had worsened over this period, 66.5% that it had remained the same and 10.5% that it had improved. Change scores on the four indicators showed a similar pattern and were significantly associated with these global judgements. Over the same period, substantial proportions lost one or more teeth, acquired new coronal or root DFS increments or experienced loss of periodontal attachment. An additional 17% complained of dry mouth. However, the only clinical indicator associated with changing perceptions of oral health was tooth loss. Of interest was the fact that rates of tooth loss were equally high among those who reported a worsening of oral health and those who reported an improvement. This suggests that the impact of tooth loss on health status may be positive or negative depending upon the condition of the teeth lost.

Factors influencing perceived treatment need and the dental attendance patterns of older adults.

To identify variables influencing perceived treatment need of older individuals and to identify predictive variables for reported dental attendance. Cross-sectional study using a self-report, posted questionnaire. Two electoral wards, one deprived and one affluent, in the city of Liverpool in 1994. Samples of older individuals (aged 60-65) were selected at random using the FHSA register as a sampling frame. A total of 500 questionnaires were distributed, 250 to each ward. The measuring instrument included the Subjective Oral Health Status Indicators (SOHSI). 342 questionnaires (68.4%) were returned. There was a highly significant (P < 0.001) association between living in a deprived area and reported poor dental attendance. Recent pain experience and concern about oral health and appearance were significant predictors for perceived treatment need. The main factor predicting subjective need for treatment was a reported history of regular, asymptomatic visiting. Such individuals were nearly six times more likely to have a perceived treatment need than poor attenders. Identification and quantification of these variables is necessary in order to promote regular, asymptomatic dental attendance and for the future planning of dental services for older individuals.

Using subjective oral health status indicators to screen for dental care needs in older adults.

A study was undertaken to assess the ability of a number of subjective oral health status indicators to identify community-dwelling older adults who need dental treatment. The indicators consisted of a single-item self-rating of treatment need, a 15-item psychosocial impact index and the 49-item Oral Health Impact Profile (OHIP). Data for the study were collected as part of an oral health survey of Canadians aged 50 years and over. The associations between these subjective indicators and clinically defined dental treatment needs were assessed using statistics for determining the predictive power of a diagnostic test. Although there were statistically significant associations between the subjective and clinical measures, values for statistics such as sensitivity, positive predictive values and positive likelihood ratios were low. Although the measures did not perform well as screening tests, they did identify a sub-group of individuals whose clinical conditions impacted significantly on daily life and who would probably benefit the most from dental treatment. In this respect, the subjective measures assessed here can themselves be interpreted as indicators of need which complement conventional clinical measures of needs for dental care.

Association between clinical and subjective indicators of oral health status in an older adult population

Since the mid-1970s a number of investigators have developed measures of the extent to which oral disorders compromise functional, social and psychological well-being. They have also examined the associations between clinical indicators of oral health status and these subjective indicators. In general, these associations have been inconsistent and weak. One reason for this might be that the subjective indicators employed were rudimentary and insensitive to the health outcomes of oral disorders. The development of the Oral Health Impact Profile, a more sophisticated measure of the health outcomes of oral disorders, provided a method to examine this hypothesis. Using data from an oral health survey of older adults, we examined the associations between OHIP scores and a variety of clinical indicators of tooth loss, caries and periodontal disease. Even with this measure the associations were predominantly weak, the strongest of the correlations being 0.53. We also examined the influence of personal and sociodemographic characteristics on the relationship between tooth loss and its psychosocial outcomes. Five variables reflecting expectations and resources explained as much variance in OHIP scores as did the number of missing teeth. This analysis illustrates the essential distinction between disease and health and the way in which measures of oral health can be used to pursue fundamental issues in behavioural science and health services research.

Evaluation of subjective oral health status indicators.

This paper reports the results of a study to evaluate the performance of a battery of subjective oral health status indicators originally developed for use in large scale surveys of older adults. The aim was to assess their generalizability, efficiency, reliability, and validity when used in a study of adults aged 18 years and over and to compare their performance with respect to younger and older adults. Data were collected by means of a mail survey and self-complete questionnaire of a random sample of the population aged 18 years and older. The results suggested that the measures were sensitive to the oral health concerns of adults of all ages and that item nonresponse was within acceptable limits. Test-retest and internal consistency reliability statistics were good and all hypotheses designed to assess concurrent and construct validity were confirmed. The results confirm an earlier, but more limited, evaluation and suggest that these indicators are useful for descriptive oral health surveys of general populations.

Trends in Oral Health in the Aging Population

Increased survival of the natural dentition, persistence of periodontal disease, deterioration of prior dental restorations, root surface caries, and continued incidence of oral cancer represent a complex of emerging oral health problems of the aged in the United States. Additional data on the epidemiology of oral mucous membrane syndromes will help to characterize the prevalence of these diseases in the aging population as well. Improvement in the utilization and accessibility of dental services by the aging cohorts will contribute to the prevention of oral disease in the future. Combined with the substantial growth in the size of this cohort of the population and alterations in the prevalence of these oral health status indicators, changes in the need for and projected utilization of professional oral health services can continue to be anticipated. Clinical research directed toward assessment of efficacy of treatment modalities for prevention of dental disease and maintenance of dental health are essential for the projection of dental health manpower needs for the future. This should also lead to the development of appropriate academic and training programs to meet the changing needs of the elderly.
