The purpose of this study is to screen individuals who wear a lower partial denture to determine their eligibility for future studies. These future studies will focus on biofilm growth, which is a layer of bacteria that can form on surfaces, and methods for removing it. Biofilm can affect oral health, making it important to find ways to manage it effectively.

Participants in this study will have their partial dentures examined to see if they are suitable for use in upcoming research. This involves checking if the dentures can accommodate specific specimens needed for the study. Participants will be asked to wear a newly fabricated study partial denture, replacing their current one, during future studies.

• Who can participate: Adults who wear a removable mandibular partial denture and have no active caries or periodontal disease may qualify. Participants must also be willing to wear a newly fabricated study partial denture and provide written consent for denture examination. Pregnant or nursing individuals and those with certain medical histories are excluded.
• Study details: Participants will be screened to determine if their current partial dentures can support study requirements. This includes the placement of specific specimens on the dentures. Participants must consent to these examinations.
