a
The linear extent of lesions in point plane and recording the depth of penetration are under 3 headings: enamel only (E), slight dentinal (Ds) and extensive dentinal (Dx).
b
Each of 4 groups was divided into female (F) and male (M) two sub-groups.
The data represent the sulcal carious lesions score according to a modified Keyes in this study. Shapiro–Wilk tests and Bartlett's tests showed that the data were nonparametric. By using UA159 as a reference, significant differences were determined using the Kruskal–Wallis test and least significant difference (LSD) multiple comparisons test. Asterisks indicate P < 0.05.
