Overview

Randomized trial assesses salivary flow rate and pH in dental students, revealing significant beverage effects.

Key Points

  • The aim is to assess the impact of caffeinated and non-caffeinated beverages on salivary flow rate and pH among dental students.
  • Conducted an interventional study with 60 undergraduate dental students randomly divided into four beverage groups: tea, soft drink, milk, and fruit juice.
  • Collected unstimulated saliva samples at baseline, 5 minutes, and 15 minutes post-consumption of beverages.
  • Analyzed salivary pH using a digital pH meter and statistical methods including Kruskal-Wallis and post hoc Bonferroni test.
  • Significant differences in salivary flow rate were observed in all groups except milk (P < 0.05).
  • Salivary pH levels fluctuated significantly over time in all groups (P < 0.001).
  • Soft drinks demonstrated a significantly lower pH immediately after consumption compared to other beverages (P < 0.05).
