Effect of IgY on rat gingivitis and bad breath induced by P. gingivalis. The scores for oral health index are shown as mean ± SD (n = 3). *Means different at p < 0.05. For PI, p = 0.027, 0.025 compared the control with the high-dose and low-dose, respectively. For GI, p = 0.011, 0.032 compared the control with the high-dose and low-dose, respectively. For HI, p = 0.029, 0.036 compared the control with the high-dose and low-dose, respectively
