Ranking Analysis of Tribological, Mechanical, and Thermal Properties of Nano Hydroxyapatite Filled Dental Restorative Composite Materials Using the R-Method

R-method as multi criteria decision-making method was proposed to determine the ranking of alternatives and performance criteria or attributes of dental composite materials. Five alternatives (DHM0, DHM2, DHM4, DHM6, and DHM8: nomenclatures of micro-nano ceramic particulate filled dental restoration composites) and 14 attributes (performance criteria) were considered in this research. The decision-maker determined the relevance of each rank and then attributed it to the performance criterion. In a similar manner, the options were ranked in relation to each performance criterion according to the associated performance criteria. Therefore, the order of the ranks of dental composites is DHM8 (1st rank) > DHM4 (2nd rank) > DHM6 (3rd rank) > DHM0 (4th rank) > DHM2 (5th rank). The suggested technique is showed simpler and advance compared to the other generally employed decision-making techniques.
