The data from a dental health survey of an Australian employee group in Brisbane were used to test the value of dental health programmes at the workplace as a means of improving general dental health. The amount and complexity of treatment needs were investigated. Although both dental caries and periodontal disease were widespread, few of the employees had major treatment needs, most requiring minimal, simple dental care. Because of the minor treatment needs of a relatively static group of employees, the viability of a dental practice at work with emphasis on restorative dental care was questioned. Given the disease levels, the treatment needs indicated that a system based on prevention and maintenance care would be more appropriate.
