Association of salivary tagatose with modified plaque index (mPlI). The correlation between D-tagatose and mPlI, considered to be an indicator of oral hygiene status, was evaluated in 18 subjects for whom mPlI data were available. D-tagatose was found to be significantly negatively correlated with mPlI (Spearman’s correlation coefficient; r = -0.603, p = 0.008; ). It is suggested that tagatose may play a role in maintaining a low level of plaque and thus good hygiene in the oral cavity.
