Selection and ranking of dental restorative composite materials using hybrid Entropy-VIKOR method: An application of MCDM technique.

The objective of this investigation was to design the selection and ranking of dental restorative composite materials using hybrid Entropy-VIKOR as the MCDM method. Eleven performance defining attributes (PDAs) of dental composites were considered to investigate the best formulation among the dental composites. The weight criteria of various PDAs of the dental composite were calculated by the Entropy method: PDA-1(0.0527), PDA-2 (0.0113), PDA-3(0.1692), PDA-4(0.1291), PDA-5(0.0207), etc. The VIKOR method was employed to demonstrate the rank of dental composites. As per the VIKOR method, the first rank was obtained by DHZ6, the second rank was by DHZ8, the third rank was by DHZ4, the fourth rank was by DHZ2, and the lowest rank was by DHZ0. The Hybrid Entropy-VIKOR method holds significance in the biomedical realm due to its capability to effectively address complex decision-making scenarios. Its ability to account for multiple criteria, uncertainties, and compromise solutions makes it particularly useful for enhancing decision-making processes in the biomedical field, where selecting the most suitable options is critical for patient outcomes and healthcare advancements.

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

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.
