NCT05852145

Brief 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.
