Oral Health and Microbiology

Understanding how materials interact with oral tissues, saliva, and other factors in the oral environment, to ensure their efficacy and biocompatibility.

Biochemistry helps understand the biochemical processes of oral microorganisms, and their role in oral health and disease, which is essential for diagnosing and treating conditions like dental caries and periodontal diseases.

Buffering capacity, antimicrobial properties, and demineralization capabilities.
