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.
评估在一个发展中的口腔卫生保健系统中，有牙成年人的保险状况与所接受服务类型之间的关系。
在伊朗德黑兰进行基于电话访谈的横断面调查。四名经过培训的访谈员使用结构化问卷收集数据。在1531名接听电话的受试者中，224名年龄小于18岁；在其余1307名受试者中，221名（17%）拒绝参与，85名（6%）因无牙或报告未进行过牙科就诊而被排除，最终样本中有1001名符合条件的受试者。问卷涵盖保险状况、社会人口统计学特征、刷牙频率、就诊原因、上次就诊以来的时间以及当时接受的牙科服务。数据分析包括卡方检验和逻辑回归。
受试者中，71%拥有牙科保险。未参保者比参保者更有可能报告拔牙情况（比值比=1.5）；对于所有其他治疗，未发现根据保险状况存在差异。在参保受试者中，因问题就诊者（比值比=6.0）或受教育程度低者（比值比=2.3）拔牙的可能性更大。
在伊朗这个口腔卫生保健系统尚在发展的国家，牙科保险对所报告的牙科服务影响较小。
