Brief summary

The study was conducted to measure the effectiveness of Black Tea in reducing the deposits on teeth. It also compares the effect between use of black tea mouthwash and green tea mouthwash to that of chlorhexidine in reducing plaque deposition on teeth in a two weeks long clinical trial among adults of 18-40 years of age.

Detailed description

The study titled Effectiveness of Black Tea Mouthwash on Plaque formation: A Randomized Controlled Clinical Trial conducted at Department of Periodontics,during February 2015 till July 2015 included three interventional arms with 15 subjects each who had chronic generalized plaque-induced gingivitis. All subjects underwent scaling and randomly allocated into three groups as Black tea,Green tea and Chlorhexidine. Those in black tea, green tea and Chlorhexidine groups advised to rinse with 0.5% Black tea, 0.5% green tea and 0.12% Chlorhexidine aqueous based solutions for 30 seconds twice daily half an hour after brushing teeth respectively. Gingival Index (Loe and Silness 1963) and Plaque Index (Silness and Loe, 1964) recorded at baseline and 2 weeks after intervention in all subjects. Results were analyzed using SPSS Statistical software version 20.
