Table 2.

Mean lesion depth and mean lesion depth progression in the control and resin infiltration groups (mean ± SD).

Groups	Mean lesion depth (µm) ± SD		Within-group p Value	Mean lesion depth progression ± SD	Between-group p Value
Groups	Before aging	After aging	Within-group p Value	Mean lesion depth progression ± SD	Between-group p Value
Control group	254.88 ± 21.07^A	387.75 ± 20.94^B	<0.001	132.88 ± 4.18^a	<0.001
Resin infiltration group	188.38 ± 17.42^C	240.69 ± 17.48^D	<0.001	52.31 ± 4.16^b	<0.001

Different capital letters indicate statistically significant differences in the same row (between before and after aging in the same group) (p < 0.05).

Different lower-case letters indicate statistically significant differences in the column (between resin infiltration group and control group) (p < 0.05).
