Understanding how a bacteria causes tooth decay

Official title: Structural and Functional Studies on the Glucosyltransferases of the Dental Caries Pathogen Streptococcus mutans

Funded at University of Alabama at Birmingham · NIH-11167778 · Data updated 2026-11-12

This study is looking at how a common bacteria called Streptococcus mutans causes tooth decay by using special enzymes to stick to your teeth and create harmful sugars, with the hope of finding better ways to prevent or treat cavities.

Who could benefit from this research

Could help

Ideal candidates for this research are adults over 21 years old who are at risk for or currently experiencing dental caries.

Less likely to help

Patients who do not have dental caries or are under 21 years old may not benefit from this research.

What this research studies

This research investigates the mechanisms by which the bacteria Streptococcus mutans contributes to dental caries, a common tooth decay disease. It focuses on the role of specific enzymes called glucosyltransferases that help the bacteria attach to teeth and form biofilms. By studying how these enzymes produce different types of sugars from dietary sucrose, the research aims to uncover the molecular processes that lead to tooth decay. This knowledge could help in developing new strategies to prevent or treat dental caries.

Why it matters

Potential benefit: If successful, this research could lead to innovative treatments or preventive measures for dental caries, improving oral health for many individuals.

How similar studies have gone: Previous research has shown success in understanding bacterial mechanisms related to dental diseases, suggesting that this approach could yield valuable insights.
