Evidence from correlation and experimental studies supports the view that availability of dental insurance increases both utilization of services and oral health. These effects are most pronounced for individuals with middle or low incomes--those most in need of care. Defining optimal levels of care and the most effective distribution of resources remains, however, an evolving and still unanswered question.
相关性研究和实验研究的证据支持了这样一种观点，即牙科保险的可获得性会增加服务的利用率和口腔健康水平。这些影响在中低收入人群（那些最需要护理的人）中最为明显。然而，确定最佳护理水平和最有效的资源分配仍然是一个不断发展且尚未得到解答的问题。
