Treatment of decayed teeth with an extensive loss of dental tissue is a challenging procedure in pediatric dentistry. With the developments in digital dentistry, the search for the choice of restorative material still continues. The aim of the study was to evaluate the mechanical and physical properties-specifically surface roughness, micro-hardness, and color difference-of 3D-printed and CAD-CAM-produced resin-based restorative materials after thermocycling. The goal was to assess whether these materials are suitable for use in pediatric crowns based on their in vitro performance in these properties. A total of ninety (14 x 12 mm) specimens in 1.5 mm thickness were prepared from 5 different restorative materials (Crowntec, Cerasmart, Tetric CAD, Vita Enamic, Lava Ultimate). The initial assessments were held for color parameters, average surface roughness, and micro-hardness. The specimens were subjected to thermocycling (10,000 cycles, 5-55 degrees C). The measurements were repeated, and color difference values were calculated. The results were statistically analyzed (alpha = 0.05). The results revealed that the Vita Enamic had higher color stability (P = 0.034). The micro-hardness of Vita Enamic was the highest, and the Crowntec revealed the lowest micro-hardness value (P < 0.05). The surface roughnesses of Vita Enamic and Crowntec were found to be higher than the other materials. The aging procedure has significantly enhanced the surface roughnesses of both Cerasmart and Vita Enamic (P = 0.034). However, their micro-hardness values were not affected by thermocycling. According to the results of this in vitro study, CAD-CAM-produced resin-based restorative materials exhibited superior physical and mechanical properties compared to 3D-printed resin.
