ClinConnect Summary
This study is testing whether kissing a partner after drinking sugary or fermented drinks can help saliva return to a neutral, healthier pH faster, potentially protecting teeth from cavities. There are three study groups: a no-kiss control group that just waits for saliva to neutralize, a group where only one person in the couple drinks the beverage and they kiss for 40 seconds, and a group where both people drink the beverages and then kiss. The main outcome is how quickly saliva pH rises back to neutral, measured with a pH meter every 5 minutes for about 40 minutes after the drink.
Eligible participants are healthy adults aged 18–30 who have good oral health and are not taking medicines that affect saliva pH, and who do not have oral abscesses. The study is being done in Guayaquil, Ecuador at the Catholic University Santiago de Guayaquil and is currently enrolling by invitation, with about 45 participants expected. Each participant will have a baseline saliva pH checked, receive one of the beverages (including options like soda or non-alcoholic beer), and then follow their assigned group’s procedure, with eight pH measurements over 40 minutes. Results are not yet available.
