Introduction: To achievement Universal Health Coverage, one of the target groups is refugees that have been provided basic health insurance for this population. The purpose of the present study was to compare the inpatient costs, in drugs, surgery, laboratory and other paraclinic, imaging, and resource allocation of inpatient costs and burden of inpatient in the two years before and after basic health insurance.
Methods: This study is a descriptive-analytic and applied type. The research environment was the university hospitals of Tehran province and the statistical population of the refugee hospitalization records during two years before and after the implementation of insurance. Cluster sampling was performed in two stages. At first, 55 hospitals of the province, 15 hospitals and then 1575 samples in each period, were randomly selected. Data were analyzed by SPSS.
Results: By implementation of basic health insurance, the average share of refugees from inpatient costs was 13.50% (P <0.001), the share of supplementary insurance was 0.04% (P <0.001), the share of hospital discounts was 9.99% (P <0.001). Burden of inpatient increased by 52% (P <0.001). The average share of drug and surgery costs decreased by P = 0.002 and P <0.001, respectively, and imaging services increased by P <0.001. Laboratory and other para clinics did not show a significant difference.
Conclusion: Basic health insurance reduced patient share and hospital discounts and increased burden of inpatient. However, given the low population coverage, it seems necessary to reconsider the dimensions of Universal Health Coverage, and especially population coverage.

Introduction: Health has always been one of the most important concerns of mankind, and without oral and dental health, the body's general health cannot be guaranteed. Having health insurance has always been one of the factors facilitating the use of health services and this study is aimed to identify and investigate the impact of insurance coverage on the use of family dental services in Iran.
Methods: The present study is a descriptive-analytical and cross-sectional study based on data from National Expenditure Survey by Statistics Center of Iran during 2013-2012. Logistic regression model was used to estimate the effect of independent variables on the dependent variable. The sample size of the study was 116469 households in rural areas and 112685 households in urban areas and 229154 households in the country as a whole. Data were analyzed using Microsoft Access, Microsoft Excel and 14 STATA software.
Results: Of the 229,154 households surveyed, 11,392 households (4.98%) had dental services during the 6-year period. The results show that provinces with a high level of development (in terms of access to health services) had higher use of dental services (p-value<0/001). Urban households with insurance coverage, more literate people, and households with fewer elderly people have used dental services (p-value<0/001). Wealthier households (higher income quintiles) than poor households (lower income quintiles.  And families that had self-care (using floss, toothbrushes and toothpaste) had more dental services than families who did not (p-value<0/001).
Conclusion: Effective evidence-based interventions to improve the use of dental services among uninsured households, elderly people, low education status, residents of less developed provinces, and rural households should be prioritized by policy makers and planners.
