Cost analysis of materials used in Class III, IV and V composite resin restorations
Hebling, Eduardo; Gonçalves, Rodolfo Luís & de Paula Queluz, Dagmar
Abstract
Aim: To assess the total cost of direct and indirect materials used in Class III, IV and V composite
resin direct restorations. Methods: The calculation of costs was based on the method of variable
costing system. A list of the materials was obtained by a panel of experts and based on the
excellence standards established in the literature for dental team treatment. The cost considered
for each material was obtained from an average of the costs found in the regional supplier market
(US$1.0=R$2.12). The repetitions were obtained from Class III, IV and V cavities in artificial premanufactured
teeth. The cavities were classified as shallow, medium and deep. The materials
were quantified for each type of preparation. Seven brands of composite resins were used and
weighed on a precision scale after their insertion in each cavity. The data were analyzed by
descriptive statistics and non-parametric Friedman’s test (α=0.05). Results: The mean costs
were US$7.96 (R$16.88) for Class III restoration, US$8.13 (R$17.24) for Class IV, and US$7.84
(R$16.62) for Class V. There was statistically significant difference in cost between the types of
cavities and depth classification. The small cost difference among the different resin brands
resulted in no statistically significant differences in the total cost of the restorations. Conclusions:
The costs obtained in this survey may be used in the calculation of the final cost of restorative
procedures, helping in the management of public or private dental care services.
