Effect of Tea on Gingivitis: A Correlation Study Based on Community Survey

摘要

Hot water extract of tea (Camelia sinensis) is the cheapest and popular beverage among wide array of people. Its medicinal values have been found by tea biochemists and also by dental experts in many countries. Pharmacological properties of tea catechins in preventing dental diseases are gaining importance now. Tea contains a series of catechins that impart the myriads of medicinal values. However, whether medicinal values of catechins are silenced by additive like milk or not is still unknown. A survey-based study involving community people suffering from gingivitis has been carried out. Objective of the study was to understand whether hot water extract of tea without milk has any relevance in reducing gingivitis or not. The survey reveals a strongnegative linear correlation (r= - 0.807**) between tea extract without milk and reduction effect of gingivitis. The result also reveals that frequency of gingivitis amongst people who drink tea with milk is more (r= 0.696*) as compared to the people who drink tea without milk.
