The aim was to evaluate the cost of direct composite and glass ionomer class II molar restorations, and the theoretical cost per year of function, at Public Dental Services (PDS) in Sweden, years 2000 and 2005. Costs for patients, Social Insurance Offices (SI; Försäkringskassan), and total cost, were calculated based on fee schedules from all PDS in Sweden. Theoretical cost per year calculations were based on the median survival times (MST) of failed direct composite and glass ionomer class II molar restorations, derived from a set of clinical studies conducted in Nordic general practices. Due to lack of national statistics from SI, the number of direct restorations including more than one surface, made in adults, in general dentistry at PDS in the county of Halland were studied. From the year 2000 to year 2005, the total cost of composite class II molar restorations increased by 25%, whereas the total cost of glass ionomer restorations more than doubled. Theoretical calculations implied a higher cost per year of function for composite restorations in year 2000, whereas in year 2005, glass ionomer restorations had a higher cost per year of function. The cost of direct composite and glass ionomer class II molar restorations increased from year 2000 to 2005, at PDS in Sweden. In the context of planning public health care funding, theoretical models for cost prediction may prove useful.
An adaptation of a clinical study of 130 patients at risk of developing a pressure ulcer on the heels was performed using Canadian costs. The aim of the study was to compare the cost effectiveness of a specially shaped hydrocellular dressing (Allevyn Heel) versus that of a protective heel bandage (Soffban and gauze) in pressure ulcer prevention over an 8-week period.
