摘要
茶的药理价值已被许多国家的医学研究者发现。茶中发现的儿茶素化合物具有多种健康益处,包括减轻牙齿疾病。然而,儿茶素的牙齿-临床特性是否被添加剂如牛奶所掩盖仍未被研究。一项基于调查的研究涉及患有牙龈疾病(牙龈炎)的社区人群,以了解不加牛奶的热水茶提取物(称为冲泡茶)是否与减少牙龈炎有关。调查显示,喝茶不加牛奶与减少牙龈炎之间存在很强的负线性相关(r= -0.807**)。结果还显示,与不喝牛奶的人相比,喝牛奶茶的人患牙龈炎的频率更高(r= 0.696*)。由于该品种在茶叶种植区普遍存在,可以生产出不同种类的红茶——浓郁的CTC茶、温和的正统茶和温和的绿茶,因此研究中使用的是Tinali 17/1/54茶树品种Kuntze var, Assamica。
Effect of Tea on Gingivits: A Community-based Study
Pharmacological values of tea have been found by medical researchers in many countries. Catechin compounds found in tea impart several health benefits including mitigating dental ailments. However, whether dento-clinical properties of catechins are camouflaged by additive like milk or not has remained unexplored. A survey-based study involving community people suffering from gum disease (gingivitis) has been carried out to understand whether hot water extract of tea ( known as brew) without milk has any relevance in reducing gingivitis. The survey reveals a strong negative linear correlation ( r= -0.807** ) between drinking tea without milk and reduction of gingivitis. The results also reveal 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. Tea made from Tinali 17/1/54 cultivar of Camelia sinensis L. O. Kuntze var, Assamica has been used in the study as this cultivar is ubiquitous in tea growing areas and can produce different categories of black tea – strong CTC tea, mild flavored orthodox tea and milder green tea.
