Black Tea and Green Tea in Reducing Children Dental Caries

Dental caries is a most prevalent oral disease in children. There were tendency of diverse children drink consumption including soft drinks that attracts by its taste and flavor and causing dental caries. Earlier study suggested that tea had important element in dental caries inhibition. Hence this study was conducted to evaluate and compare pH of saliva after rinsing with green tea and black tea. Methods for his study was conducted among thirty two healthy school children between 10-12 years old. The subjects who fulfilled inclusion and exclusion criteria were selected and randomly divided into two groups. The first group had rinsing with green tea and the other group with black tea. They were asked to rinse for one minute after sugary soft drink consumption. Then salivary pH were measured using pH meter.. Statistical analysis was done using Mann Whitney test. p < 0.05 was considered statistically significant. Results of this study showed that there was no statistically significant difference among subjects rinsing for one minute with green tea and black tea after sugary soft drink consumption. But green tea showed much better effect in rising salivary pH. As the conclusion that green tea showed a promising greater rising on salivary pH than black tea after sugary soft drink consumption in children.
