Introduction- Modern adhesives have made it possible to repair rather than replace damaged restorations. Water sorption can make a substance more voluminous, function as a plasticizer, and damage the matrix structure of the substance. The materials used for dental restoration are also subjected to heat stress during routine oral activities.
Materials and method- Each material was manipulated and proportioned in accordance with the manufacturer's specifications. In total, 15 disc specimens, 5 for each group were created. In a chewing simulator (SD MECHATRONIK CHEWING SIMULATOR. CS - 4.4), samples were put for thermocycling with distilled water. The weight of the samples was taken before thermocycling (W1), and the weight (W2) was taken post thermocycling. All the samples were weighed electronically using a digital weighing scale and pre and post weight was recorded.
Results- The mean values of water sorption and the standard deviation for groups I, II, and III before thermocycling were 0.312 ± 0.0316, 0.1782 ± 0.0128 and 0.4068 ± 0. ug/mm3 respectively. The mean values of water sorption and the standard deviation for groups I, II, and III post thermocycling were 0.2644 ± 0.0494, 1.7936 ± 0.1463, and 0.3932 ± 0.1181 ug/mm3 respectively. The p value was found to be 0.0018 which is less than <0.05 and hence significant.
Conclusion- The least watersorption was seen in the glass ionomer cement infused with calcium oxide nanoparticles, followed by ordinary glass ionomer cement and Zirconomer. The differences were statistically significant.
