ABSTRACT
Background: Wettability of denture base materials plays a critical role in retention, comfort, and function, particularly in xerostomic patients. Saliva substitutes are commonly used to compensate for reduced salivary flow; however, their interaction with different denture base materials requires evaluation.
Aim: To evaluate and compare the wettability of three commercially available saliva substitutes on conventional, hi-impact, and 3D printed acrylic denture base materials.
Materials and Methods: Total 180 samples were fabricated using conventional heat-cured PMMA, hi-impact PMMA, and 3D printed acrylic resin and divided into 4 groups based on different saliva substitutes. Wettability was assessed using contact angle measurement with a drop shape analyzer. Data were analyzed using one-way ANOVA and post hoc tests with significance set at p < 0.05.
Results: 3D printed acrylic resin exhibited the lowest contact angle, indicating superior wettability. Among salivary substitutes E-saliva exhibited better wettability. Significant differences were observed among groups.
Conclusion: 3D printed denture base materials show enhanced wettability and may be advantageous in xerostomic patients. Selection of appropriate saliva substitutes further improves clinical outcomes.
