A large dental insurer has introduced a system that workers can use to compare the cost of dental plan options.

CIGNA Dental, Plantation, Fla., a unit of CIGNA Corp., Philadelphia, says it will start by offering the new, Web-based Dental Plan Cost Estimator to employers with 1,000 or more employees.

The estimator comes with an estimation option designed for users who have only a general understanding of their oral health, an option for users who know what general kind of work they need, and an option for users who know what procedures they are likely to need.
