Oral Biofilms: Unravelling microbial interactions and the role of oral care interventions
Date: Tuesday, 25 Mar 2025
Time: 2.30pm – 3.30pm
Venue: NTU School of Biological Sciences CR4 (SBS-01n-24)
Abstract:
Dental plaque represents a complex microbial biofilm community which normally exists in a benign relationship with the host, playing a crucial role in maintaining both oral and systemic health. However, it is also the cause for some of the most common diseases affecting humanity.
Oral diseases, including gingivitis, periodontitis and dental caries, are among the most prevalent health conditions worldwide, affecting approximately 3.5 billion people. While these diseases are rarely life-threatening, they have enormous burden on healthcare services with an estimated global cost of $54 billion for severe periodontitis alone.
Furthermore, the impact is disproportionately felt by the most vulnerable populations, exacerbating health inequalities. Recognising this, the World Health Organization emphasises that ‘oral health is a key indicator of overall health, well-being, and quality of life’.
This seminar will explore how the oral microbiome and dental plaque biofilms interact with oral care interventions and how these interventions can influence bacterial behaviour to support health. Drawing from recent research, including work with SCELSE, we will discuss how targeted strategies, such as different active ingredients in oral care formulations, can help maintain microbial balance and reduce disease risk.
