Introduction: With various restorative materials available and continuous evolution in the field of research for better restorative materials, it is very important to find a material with maximum desirable properties for restoring a primary tooth. Aim: The aim of the study is to compare the compressive strength, diametral tensile strength, and shear bond strength of glass ionomer cement type II (GIC II), GIC IX, and Cention N on primary tooth. Methods: Cylinder of each restorative material, GIC II (GC Corporation, Tokyo, Japan), GIC IX (GC Corporation, Tokyo, Japan), and Cention N (Ivoclar, Vivadent), of dimension 6 mm diameter × 12 mm height (according to ISO 7489:1986) was prepared to check for compressive strength, and disk of dimension 6 mm diameter × 4 mm height (according to ISO 4049 and ANSI/ADA 27) was prepared to check for diametral tensile strength. Furthermore, following the ISO guidelines 29022:2013, restorative materials from various groups were mixed and placed on the flat buccal/lingual enamel of deciduous teeth bonded to the dentin surface of the tooth were used to check for shear bond strength. All the mixing of the materials and samples making were performed by a single investigator. Universal Testing Machine was used to carry out the tests. The data obtained were subjected to ANOVA followed by post hoc Tukey's test. Intergroup comparison was done with Mann–Whitney test. Results: The compressive strength, diametral tensile strength, and shear bond strength of Cention N (Ivoclar) were significantly higher than GIC II and GIC IX (P = 0.00). Between GIC II and GIC IX, there was statistically significant difference (P = 0.00) in terms of diametral tensile strength and shear bond strength, but no significant difference was seen in terms of compressive strength (P = 0.08). Conclusion: Cention N (Ivoclar) presented with high mechanical strength and can be a good alternative to GIC II and GIC IX for restoration of deciduous teeth.
