The Impact of Sage Extract on GTS B and D Gene Expression in S. Mutans

May 5, 2025 updated by: Dina Ezz, Cairo University

The Impact of Natural Sage Extract on Glucosyltransferase B and D Gene Expression in Streptococcus Mutans: A Randomized Clinical Trial Using Real Time Polymerase Chain Reaction

Glucosyltransferases (Gtfs) play a crucial role in the pathogenesis of dental caries caused by Streptococcus mutans. Gtfs is recognized as an attractive target for effective therapeutic interventions aimed at inhibiting cariogenic biofilms.

Objective: This study evaluates the antibacterial effects of sage extract compared to chlorhexidine mouthwashes on the expression of Gtf genes in S. mutans from salivary samples of high caries risk patients over a one-month follow-up, utilizing real-time polymerase chain reaction.

Methodology: This clinical trial involves 42 participants with a high risk for caries, who are randomly divided into two groups of 21 subjects each.

Detailed Description

Glucosyltransferases (Gtfs) are essential in the development of dental caries caused by Streptococcus mutans. They are currently recognized as promising targets for effective therapeutic strategies aimed at disrupting cariogenic biofilms.

Objective: This study investigates the antibacterial effects of sage extract in comparison to chlorhexidine mouthwashes on the expression of Gtf genes in S. mutans from the saliva of patients at high risk for caries, over a one-month follow-up period, using real-time polymerase chain reaction.

Methodology: This clinical trial includes 42 high caries risk participants, who are randomly assigned to two groups, each consisting of 21 subjects.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
