Ranking and selection of dental restorative composite materials using FAHP-FTOPSIS technique: An application of multi criteria decision making technique

Abstract

In the present investigation, the optimal formulations of dental restorative composite materials were designed using hybrid FAHP (Fuzzy Analytic Hierarchy Process)-FTOPSIS (Fuzzy Technique for Order of Preference by Similarity to Ideal Solution) methodology of statistical techniques. The dental composite was composed of an organic matrix and different types and ratios of inorganic filler. The various performance defining attributes (PDAs) such as compressive strength, flexural strength, depth of cure, and polymerization shrinkage were taken into account to evaluate the optimal formulation of dental restorative composite materials. The weight criteria of PDAs was evaluated by the FAHP; PDA-1 (0.084, 0.083, 0.083), PDA-2 (0.084, 0.095, 0.102), PDA-3 (0.079, 0.097, 0.110), PDA-4 (0.084, 0.108, 0.124), PDA-5 (0.084, 0.091, 0.093), PDA-6 (0.062, 0.083, 0.113), PDA-7 (0.070, 0.081, 0.098), PDA-8 (0.058, 0.071, 0.090), PDA-9 (0.073, 0.074, 0.092), PDA-10 (0.070, 0.076, 0.089), and PDA-11 (0.157, 0.135, 0.098), respectively. The FTOPSIS is used to determine the rank of alternatives as DHZ4 > DHZ8 > DHZ0 > DHZ6 > DHZ2. The Hybrid FAHP-FTOPSIS technique was significant in ranking analysis of different dental restorative composite materials under conflicting PDAs.
