Comparative evaluation of dimensional stability and flexural strength of different light cured tray materials with self-cured tray material: an in-vitro study

Objectives: To carry out a comparative evaluation of dimensional stability and flexural strength different light cured tray materials with self-cured material as control.Materials methods: The study was carried in four groups based on the available materials. Group A (n=30) – resin (Individo Lux-VOCO™ GmbH Germany); B (n=30)- (Profibase-VOCO™ C (Plaque Photo-Willmann Pein™ D control group-self (Asian special instant Asian Acrylates™, Mumbai, India). digital micro-meter used to measure length each specimen first at 1 hour, 24 hour 48 three readings were taken up 0.001 decimal. values for measured using 3-point bending technique help universal testing machine. mean calculated by one-way ANOVA Tukey’s post-hoc test multiple group`s comparison.Results change (in mm) resins samples significantly lower than all time intervals. samples-Group (84.46±13.32 N/mm2), (83.43±14.52 N/mm2) (86.80±14.73 higher group (41.29±7.93 N/mm2)Conclusions: Light are more dimensionally stable have compared
