Different Polymerization Methods for Dentistry Amount Internal Porosities: A Systematic Review

Abstract

Data were analysed statistically using the Kruskal-Wallis test to see differences in porosity between 3 different polymerization groups in samples A, B and C. Then continued using the Mann Whitney test to see differences in porosity in each sample A, B and C. heat polymerization acrylic resin with different polymerization methods in sample A (temperature 25 ° C for 0 '→ 74 ° C for 90' → 100 ° C for 60 ') compared to sample B (temperature 25 ° C for 0' → 70 ° C for 90 '→ 100 ° C for 30') and sample C (temperature 25 ° C for 0 '→ 74 ° C for 60' → 100 ° C for 30 '). Sample C (temperature 25 ° C for 0 '→ 74 ° C for 60' → 100 ° C for 30 ') had a higher amount of porosity of the hot polymerized acrylic resin with different polymerization methods compared to sample B (temperature 25 ° C during 0 '→ 70 ° C for 90' → 100 ° C for 30 '). There was no significant difference in the amount of internal porosity in the hot polymerized acrylic resin with different polymerization methods in sample A, sample B and sample C.
