Education-related inequality in restorative dental treatment need over 11 years in two areas of Finland.

OBJECTIVES: This study aimed to analyse education-related inequality in restorative dental treatment need among adults aged 30 years and older living in Northern and Southern Finland in 2000 and 2011. METHODS: Data were taken from the Health 2000 and 2011 population-based follow-up surveys, including information gathered by interviews and clinical dental examination. Final effective sample sizes were 2423 people in 2000 and 1192 people in 2011. Restorative dental treatment need was measured with number of decayed and/or fractured teeth (DT + FrT). Education-related inequality in number of DT + FrT and factors explaining it were analysed using the Poisson regression analysis, relative index of inequality and slope index of inequality. RESULTS: Average number of DT + FrT decreased from 2000 to 2011. Absolute and relative education-related inequalities in them decreased approximately 50% and 25% from 2000 to 2011, respectively. Tooth brushing frequency and time since last dental visit explained approximately 30%-40% of the education-related inequality. The contribution of time since last dental visit to the education-related inequality was smaller in 2011 than in 2000. CONCLUSIONS: It seems that, from 2000 to 2011, the need for restorative dental treatment decreased simultaneously with the education-related inequality in it among adults aged 30 years and older living in Northern and Southern Finland.

Use of oral health care services in Finnish adults - results from the cross-sectional Health 2000 and 2011 Surveys.

BACKGROUND: During the 2000s, two major legislative reforms concerning oral health care have been implemented in Finland. One entitled the whole population to subsidized care and the other regulated the timeframes of access to care. Our aim was, in a cross-sectional setting, to assess changes in and determinants of use of oral health care services before the first reform in 2000 and after both reforms in 2011. METHODS: The data were part of the nationally representative Health 2000 and 2011 Surveys of adults aged ≥ 30 years and were gathered by interviews and questionnaires. The outcome was the use of oral health care services during the previous year. Determinants of use among the dentate were grouped according to Andersen's model: predisposing (sex, age group), enabling (education, recall, dental fear, habitual use of services, household income, barriers of access to care), and need (perceived need, self-rated oral health, denture status). Chi square tests and logistic regression analyses were used for statistical evaluation. RESULTS: No major changes or only a minor increase in overall use of oral health care services was seen between the study years. An exception were those belonging to oldest age group who clearly increased their use of services. Also, a significant increase in visiting a public sector dentist was observed, particularly in the age groups that became entitled to subsidized care in 2000. In the private sector, use of services decreased in younger age groups. Determinants for visiting a dentist, regardless of the service sector, remained relatively stable. Being a regular dental visitor was the most significant determinant for having visited a dentist during the previous year. Enabling factors, both organizational and individual, were emphasized. They seemed to enable service utilization particularly in the private sector. CONCLUSIONS: Overall changes in the use of oral health care services were relatively small, but in line with the goals set for the reform. Older persons increased use of services in both sectors, implying growing need. Differences between public and private sectors persisted, and recall, costs of care and socioeconomic factors steered choices between the sectors, sustaining inequity in access to care.

Income-related inequality in perceived oral health among adult Finns before and after a major dental subsidization reform.

Objectives In Finland, a dental subsidization reform, implemented in 2001-2002, abolished age restrictions on subsidized dental care. The aim of this study was to investigate income-related inequality in the perceived oral health and its determinants among adult Finns before and after the reform. Materials and methods Three identical cross-sectional nationally representative postal surveys, concerning perceived oral health and the use of dental services among people born before 1971, were conducted in 2001 (n = 2157), in 2004 (n = 1814) and in 2007 (n = 1671). Three measures of perceived oral health were used: toothache or oral discomfort during the past 12 months, current need for dental care and self-reported oral health status. Concentration index was used to analyse the income-related inequalities. Its decomposition was used to study factors related to the inequalities. Results The proportion of respondents reporting need for dental care decreased from 2001 to 2007, while no changes were seen in reports of toothache or self-reported oral health status. Income-related inequalities in reports of toothache and perceived need for care widened, while the inequality in self-reported oral health remained stable. Most of the inequalities were related to income itself, perceived general health and the time since the last visit to dental care. Conclusions It seems that the income-related inequalities in perceived oral health remained or even widened after the reform.

Inequality in oral health-related quality of life before and after a major subsidization reform.

In Finland, a dental subsidization reform, implemented in 2001-2002, abolished age restrictions on subsidized dental care. We investigated income-related inequality in oral health-related quality of life (OHRQoL) and its determinants among adult Finns before and after the reform. Three cross-sectional postal surveys, focusing on perceived oral health and the use of dental services among people born before 1971, were conducted in 2001 (n = 2,046), 2004 (n = 1,728), and 2007 (n = 1,560). Five measures, based on the Oral Health Impact Profile-14, were used as indicators of OHRQoL. Income-related inequality and associated factors were analysed using the concentration index and its decomposition. Prevalence, extent, and severity of oral health impacts were slightly lower in 2007 than in 2001. The oral health impacts were concentrated, at all study time points, among individuals with lower income. Most of the inequality was related to self-perceived general health, tooth loss, and income. Contributions of time since the last dental visit and satisfaction with the last treatment period to the inequality decreased from 2001 to 2007. However, the contributions of these factors were already small (10-20%) in 2001. In general, OHRQoL improved slightly; however, no clear or dramatic change in inequality in OHRQoL was seen after the reform.

Income-related inequality and inequity in the use of dental services in Finland after a major subsidization reform.

OBJECTIVES: In Finland, a major oral healthcare reform (OHCR), implemented during 2001-2002, opened the public dental services (PDS) and extended subsidies for private dental services to entire adult population. Before the reform, adults born earlier than 1956 were not entitled to use PDS nor did they receive any reimbursements for their private dental costs. We aimed to examine changes in the income-related inequality and inequity in the use of dental services among the adult Finns after the reform. METHODS: Representative data from Finnish adults born in 1970 or earlier were gathered from three identical postal surveys concerning the use of dental services and subjective perceptions of oral health. Those surveys were conducted before the OHCR in 2001 (n = 1907) and after the OHCR in 2004 (n = 1629) and 2007 (n = 1509). We used concentration index and its decomposition to analyse income-related inequality and inequity in the use of dental services and factors associated with them. RESULTS: Results showed that pro-rich inequality and inequity in the overall use of dental services narrowed from 2001 to 2004. However, between 2004 and 2007, pro-rich inequality and inequity widened, so it returned to a rather similar level in 2007 as it had been in 2001. Most of the pro-rich inequality and inequity were related to regular dental visiting habit and income level. While there was pro-poor inequality and inequity in the use of PDS, there was pro-rich inequality and inequity in the use of private dental services throughout the study years. CONCLUSION: It seems that income-related inequality and inequity in the use of dental services narrowed only temporarily after the reform.

Dental attendance among adult Finns after a major oral health care reform.

OBJECTIVES: Between 2001 and 2002, all age limits restricting the availability of subsidized private dental care and Public Dental Services (PDS) were abolished in Finland. In addition, the reform aimed to address income- and residence-related disparities in access to subsidized oral health care services. The aim of this study was to analyse how dental attendance and factors associated with it changed after the reform. METHODS: We carried out three consecutive surveys on the use of oral health care services and perceived oral health. The surveys were conducted in 2001 (n = 2837), in 2004 (n = 2420) and in 2007 (n = 2296), and the study population comprised Finnish adults born in 1970 or earlier. Logistic regression analyses were used to examine factors associated with the use of the services. RESULTS: The percentage of respondents who attended dental care regularly or had used oral health care services over the past 12 months rose between 2001 and 2007. In particular, there was an increase in the proportion of subjects who used PDS. The average number of visits to a private dentist decreased between 2001 and 2007. In the regression analyses, the use of services was associated with older age, perceived lack of need for care, perceived toothache during the past 12 months, perceived good oral health, lower number of missing teeth and regular dental visiting habits. The use of private dental care services was associated with perceived good oral health and perceived lack of need for care, higher household income and older age in all three study years while the use of PDS was associated with younger age, perceived good oral health and perceived lack of need for care only in 2001. CONCLUSIONS: The use of oral health care services rose and age did not seem to be a barrier to the use of oral health care services after the reform, as was the aim of the reform. No change in the association of household income with the use of oral health care services was seen after the OHCR.
