Surface roughness changes how saliva, proteins, and microorganisms interact with the prosthesis. Irregular areas may provide conditions that support accumulation of oral biofilms, making the denture more difficult to keep clean. Because biofilm persistence can contribute to odor and denture-related stomatitis, controlling roughness is important for comfort, hygiene, and oral health.
These properties influence the initial interaction between the denture and its oral environment. Wettability and surface free energy affect how saliva and proteins spread or attach, while porosity can alter the surface available for microbial interaction. Together, they help determine cleanliness, biofilm behavior, odor, biocompatibility, and the performance of surface treatments.
Surface treatments are intended to modify characteristics that control biological and physical interactions at the denture interface. Polishing can address surface texture, while coatings or other approaches may alter how the material contacts saliva, proteins, and microorganisms. Their value is assessed through effects on microbial resistance, durability, and biocompatibility.
Evaluation should consider roughness, porosity, wettability, and surface free energy, because each property contributes different information about the treated material. Researchers can relate these characteristics to interactions with saliva, proteins, microorganisms, and oral biofilms. Linking surface measurements with cleanliness, odor, comfort, and stomatitis-related outcomes gives the assessment clinical relevance.
They are particularly relevant when denture cleanliness, odor, comfort, microbial resistance, or tissue compatibility is a concern. Modifying the surface can complement clinical maintenance by addressing material properties that influence biofilm interaction. This supports denture designs and maintenance approaches aimed at reducing adverse oral effects while preserving useful prosthetic function.
These studies can guide efforts to improve microbial resistance, durability, and biocompatibility in denture design. They also clarify how the prosthesis interacts with saliva, proteins, microorganisms, and oral biofilms. The resulting information may support better cleanliness and comfort, reduce odor, and help address the risk of denture-related stomatitis through improved maintenance strategies.
