Abstract

This study aimed to know the effect of green tea on the dental plaque index on;the lingual surfaces of the mandibular anterior teeth among the selected dental students of Cebu Doctors' University A.Y. 2015-2016. The study used the randomized controlled trial design. The study was conducted in the Dental Infirmary, College of Dentistry, Cebu Doctors' University. Ten participants were selected according to a set of inclusion and exclusion criteria. Five participants were randomly selected for each of the experimental and control groups. The study used the Modified Quigley-Hein Plaque Index to measure the plaque scores which was designed by G.A. Quigley and J.W. Hein and was modified by the researchers.


After local application of 0.12% chlorhexidine gluconate through mouthrinse on the lingual surfaces of the anterior teeth, the dental plaque index score of tooth numbers 43,42,41,31,32, and 33 reduced from 6.6mm to 3.4, from 5.8mm to 3.4mm, from 6mm to 3.6mm, from 5.8mm to 2mm, from 5.8mm to 4.4mm and from 6.2mm to 3.4mm respectively. Similarly, the dental plaque index score of the experimental group using Lipton Clear Green Tea solution with the same tooth numbers, dental plaque decreased from 7mm to 5.6mm, from 6.6mm to 5mm, from 6.2mm to 4.6mm, from 5.8mm to 3.2mm, from 6.8mm to 4.4mm, from 7.8mm to 5.4mm respectivelyl. The control and the experimental group shows reduction of the mean dental plaque index score from before it was applied and after 7 days of application. After 7 days of application, experimental group had significantly higher plaque index scores compared to the control group with a difference of 2mm of tooth number 43 at 0.05 level of significance, U = .000, p <0.05a difference of 2mm on the tooth number 42 at 0.05 level of significance, U = 2.000, p <0.05, a difference of 1mm of tooth number 31 at 0.05 level of significance, U = 2.500, p U = .000, p < 0.05. There was no significant difference in the post-treatment plaque index score between 0.12% chlorhexidine and green tea of tooth numbers 41 and 32, U = 3.00, p > .05 and U = 12.00, >.05. This implies that results of experimental and control group of tooth # 41 and #32 were comparatively effective.


Based on the findings, the researchers concluded that Lipton Clear Green tea is effective in reducing the dental plaque index on the mandibular anterior teeth of the selected dentistry students of Cebu Doctors' University A.Y. 2015-2016. Moreover, Lipton Clear Green Tea was comparatively effective as 0.12% chlorhexidine gluconate on tooth numbers 41 and 32 when used to decrease the dental plaque index. The researchers strongly recommend the use of the results of the study as source of added literature and background regarding green tea for conducting further studies about its effects on the dental plaque index or other related studies. As the study was conducted on a seven-day experimental period, further researchers are encourage to conduct studies longer that seven days comparing the results of the same experiment in which it would be precisely tested. As the study was based on the previous study conducted by the US Department of Agriculture wherein the catechins present in green tea when steeped for 3 minutes in a 200ml of water is 266.68, the researchers suggest to steep the green tea bag longer than 3 minutes to get a higher amount of catechins.
