Oral Changes With Caloric and no Caloric Sweeteners

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.

Conditions

• pH
• Microbiome

Interventions

DRUG

Stevioside

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

DRUG

Sucrose

250 ml of natural water added with 25 gr of sucrose 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
