    ABSTRACT: To assess the relationship between insurance status and type of service received among dentate adults in a developing oral health care system. A cross-sectional survey based on phone interviews in Tehran, Iran. Four trained interviewers collected data using a structured questionnaire. Of 1,531 subjects answering the phone call, 224 were <18 years; of the remaining 1,307, 221 (17%) refused to participate, and 85 (6%) were excluded as edentate or reporting no dental visit, leaving 1,001 eligible subjects in the sample. The questionnaire covered insurance status, socio-demographics, frequency of tooth brushing, dental attendance as reasons for, and time since last dental visit, and dental service received then. Data analysis included the chi-square test and logistic regression. Of the subjects, 71% had a dental insurance. Those with no insurance were more likely to report tooth extractions (OR=1.5) than those with an insurance coverage; for all other treatments no differences according to the insurance status appeared. Among the insured subjects, extractions were more likely for those reporting a problem-based dental visit (OR=6.0) or having a low level of education (OR=2.3). In Iran, with its developing oral health care system, dental insurance had only a minor impact on dental services reported.

    ABSTRACT: To investigate patients' reasons for selecting a dental clinic given their choice of free or highly-subsidized dental services. The study was based on cross-sectional data obtained through phone interviews with adults in Tehran, Iran. The present study included those entitled to free or highly-subsidized dental services (n = 726). The data covered the patients' awareness of subsidized dental services and type of dental clinic for their most recent visit and their reasons for selecting that clinic. Awareness of subsidized dental services was dichotomized as being either aware or unaware of such subsidy. The type of clinic was dichotomized as providing either free or highly-subsidized (FHS) or fully out-of-pocket paid (FOP) services. Free format answers about the subjects' reasons for selecting a particular clinic were later sub-grouped as: convenient access, good technical aspects, good interpersonal aspects, low or reasonable fees, recommendation by a friend, and no reason. Socio-demographic status was based on background. Data analysis included the chi-square test and logistic regression model. Of the subjects (n = 726), 60% were women and 58% were under 35 years of age. The subjects' mean age was 33.5 years with no difference by gender (P = 0.24) and the majority had public insurance (91%). Of all the subjects, 60% selected FOP. Good interpersonal aspects were the strongest reason for selecting FOP (OR = 4.6), follow by good technical aspects (OR = 2.3). Those subjects who were unaware of their benefit had 4.6 times the odds of selecting FOP. Despite the opportunity to use highly-subsidized dental services, good interpersonal and good technical aspects lead patients to select private dentists and to pay fully out of pocket.

    ABSTRACT: To find out the relationship between dental insurance and demand for dental care, the present study evaluated impact of insurance scheme on adults' dental check-ups in a developing oral health care system. The target population included adults in the city of Tehran where the only telecommunication company provides 90% of the 1.9 million households with a fixed telephone. Of the 1531 subjects who answered the phone call, 224 were outside the target age (under 18), 67 said that they never had visited a dentist, and 221 refused to respond, leaving 1019 subjects in the final sample. Each interview lasted 15 minutes and was carried out using a structured questionnaire with fixed and open-ended questions. 71% of the subjects reported having dental insurance and 16% having visited a dentist for a check-up; 55%, more women than men, reported having had a dental visit within the past 12 months. The present results revealed the positive relationship between insurance and demand for dental care. Those having dental insurance were more likely to go to check-ups despite their generally low rate found in this country with a developing oral health care system. In such countries, health insurance schemes should therefore include obligatory regular dental check-ups to emphasize prevention-oriented dental care.

    ABSTRACT: Abstract Nationwide and regional participation in the newly started public dental care system, occurrence of caries and proportion of children registered to be in need of restorative treatment during 1974–1979 were studied in 3-5-year-old Finnish children. The data were collected from the annual reports of municipal dental health centers. The mean annual proportion of children participating in the care increased from 27% in 1974 to 71 % in 1979. A clear improvement was noticed in each county, especially in areas where the earlier situation was poor. During the study period an average proportion of entirely caries free children increased from 24% at the beginning lo 57% at the end of the study. The mean annual proportion of children recorded to be in need of restorative care decreased from 61% at the beginning to 32% at the end of the study period. The mean dmft value decreased from 3.7 in 1974 to 1.7 in 1979. A strong inverse relationship existed between the dental health at the beginning of the study period and the extent of changes in dental health during the 6-year-period. Thus regional differences have greatly diminished since the introduction of the public dental care system.

    ABSTRACT: The consumption of oral health services among 4-16-yr-old children in Finland is described, including an analysis of heavy consumption. Data representative of all Finnish children were collected for 4518 children from municipal health centers and homes. The response rate was 85%. Children with orthodontic visits during the year were excluded from the analyses. Of the preschoolchildren 12% and of the school-age children 4% did not use any oral health services during the studied year. Non-users did not differ from the others in terms of socioeconomic status, distance to a health center or type of residential area. Public oral health services were used very unevenly. Half of the children consumed only one-fifth of the services and the next one-third used about one-third of the services. The heavy consumers, about one-fifth of the total, used as much as half of all the services. Among preschoolchildren, the heavy consumers were mainly from lower socioeconomic groups. In contrast, no clear predictive factors were found for heavy consumption among the schoolchildren. Heavy consumers had more both treated and untreated caries than the other children did. Their treatment was mainly restorative; at least half of them did not receive adequate preventive care. Finnish public oral health care clearly should make more efforts to ensure that heavy consumers of dental services do not remain so.

    ABSTRACT: Temporal trends of caries frequency in 6-17-year-old children in Finland and its counties during 1975-79 are reported. Initially the attendance rate was 70%: during the 4-year follow-up it increased to 84%. The cross-sectional annual proportion of children needing curative treatment diminished from 80% to 67% at the age of 8 years; the changes among the 12- and 16-year-old children were 78-66% and 86-76%, respectively. The proportion of entirely caries-free children increased from 2.5% to 9.2% at the age of 8 years, only a slight increase was found in the older age groups. The mean DMFT value decreased continuously at all ages: in the 8-year-old children it decreased from 2.7% to 1.7%, in 12-year-olds from 6.7% to 5.2% and at the age of 16 from 13.4% to 11.6%. The caries scores decreased most in areas where the initial values were highest. In the county with high fluoride levels, where the initial caries scores were smallest, only slight improvement in the caries situation was found; this indicates no major change in recording of caries. Although a simultaneous improvement of the national attendance rate and the caries scores were observed, no consistent associations were found between the changes in the attendance rate and the changes in various caries indices when age and geographical area were considered in the analyses. It is concluded that the marked decrease in caries frequency is mainly due to preventive measures.
