Oral Changes With Caloric and no Caloric Sweeteners
Effect of the Consumption of Beverages Added With Stevia Rebaudiana on Oral pH and Dental Biofilm in Adolescents
Hospital Infantil de Mexico Federico Gomez
52 participants
Aug 1, 2025
INTERVENTIONAL
Conditions
Summary
The objective of this clinical trial is to compare the effect that the intake of beverages without sweeteners, added with non-caloric sweeteners (stevioside) and caloric sweeteners (sucrose) on oral pH and dental biofilm microbiome in Mexican adolescents. Participants will drink on different occasions a beverage without sweetener, a beverage added with stevioside or a beverage added with sucrose. The researchers will compare the changes that each one causes in salivary pH, dental biofilm pH, dental biofilm bacterial proliferation and dental biofilm microbiome.

- Periodontal infections
Interventions
250 ml of natural water added with 0.1 gr. of stevioside should be drunk * Salivary pH will be analyzed at 0,5,10,15,30,45 and 60 minutes later * Dental biofilm pH will be analyzed at 0,5,10,15,30,45 and 60 minutes later * Streptococcus mutans and Strepcotoccus sobrinus proliferation in dental biofilm ( PCR copies) will be analyzed at 0 and 120 minutes later * The relative abundance of Streptococcus mutans and Streptococcus sobrinus in dental biofilm will be analyzed using Amplicon Sequence Variant at 0 and 120 minutes later
