Background: A major objective in the management of deep carious lesions involving proximal surfaces of primary molars is to control marginal leakage. This could occur due to dimensional changes or failure in the adaptation of pulp capping materials to the prepared cavity. Evaluation of microleakage is important for assessing the success of newer pulp capping materials.
Introduction: Biodentine exhibits good sealing ability but possesses longer setting times and handling difficulties, which might delay the placement of the final restoration. The sealing ability of newer dual-cure calcium silicate-based material in TheraCal PT in class II cavities of primary molars is not known. Hence, the current study aimed to evaluate and compare the microleakage of Biodentine and TheraCal PT in primary molars.
Materials and methods: Extracted, noncarious primary molars (n = 28) were collected, and standardized class II cavities were prepared and restored with Biodentine (group I) and TheraCal PT (group II). Following this type, IX glass ionomer cement (GIC) was placed and polished. Microleakage was assessed using the dye penetration method, and data obtained through stereomicroscopic analysis were statistically analyzed.
Results: The mean microleakage score observed in group I was 2.0 ± 1.3 MPa, and in group II was 1.0 ± 1.1 MPa. Comparable sealing ability was observed between both groups (p = 0.061).
Conclusion: TheraCal PT could be used as a suitable alternative to Biodentine for use in vital pulp therapeutic procedures in children to reduce the treatment time and improve sealing ability.
