The paper examines productivity in the provision of public dental services in Norway. The main responsibility of the public dental services is to provide care for all children up to 18 years of age. Most dental care is provided by public dental officers. Productivity was measured by estimating a stochastic production frontier from input and output data from the public dental service in Norway. The results indicate that there are increasing returns to scale. Our measure of technical efficiency showed that the level of inefficiency is fairly small. However, the inefficiency is greater when estimated from a deterministic production frontier rather than from a stochastic frontier. One limitation of the present methodology is that it does not say anything about the level of efficiency in the Norwegian public dental service in absolute terms. A greater level of inefficiency would have been identified if a few counties had performed clearly better than the rest.
本文考察了挪威公共牙科服务的生产率。公共牙科服务的主要职责是为所有18岁以下儿童提供护理。大多数牙科护理由公共牙科官员提供。通过根据挪威公共牙科服务的投入和产出数据估计随机生产前沿来衡量生产率。结果表明存在规模报酬递增。我们的技术效率衡量显示，无效率水平相当小。然而，从确定性生产前沿而非随机前沿估计时，无效率更大。本方法的一个局限性是，它没有从绝对意义上说明挪威公共牙科服务的效率水平。如果少数几个县的表现明显优于其他县，就会发现更高水平的无效率。
