Abstract:
OBJECTIVES:The aim of this study was to determine whether conventional black tea and a herbal tea were capable of eroding dental enamel. A further aim was to investigate whether herbal tea of the type tested eroded dental hard tissues to a greater or lesser extent than conventional black tea. METHODS:Three groups of 21 teeth were exposed to a conventional black tea Typhoo (Group A), a herbal tea Twinings Blackcurrant, Ginsing and Vanilla (Group B) and water, which acted as a control (Group C). Sequential profilometric tracings of the specimens were taken, superimposed and the degree of enamel loss calculated as the area of disparity between the tracings before and after exposure. RESULTS:Conventional black tea and herbal tea, of the type tested, both resulted in tooth surface loss. Tooth surface loss, which resulted from exposure to herbal tea (mean 0.05mm(2), s.d. 0.02), however, was significantly greater (P=0.00) than that which resulted from exposure to conventional black tea (mean 0.01mm(2), s.d. 0.00) and water (mean 0.00mm(2), s.d. 0.00). CONCLUSIONS:It was concluded that herbal tea and conventional black tea of the type tested result in erosion of dental enamel. The erosive effect of the herbal tea of the type tested was five times more severe than that of the conventional black tea tested. The cumulative effects of regular consumption of herbal tea of the type tested are likely, therefore, to be of clinical significance.
