Multiple comparisons of pH in tongue coating between phases

Phase	Group SC	Group TS	Group ES	Group EO	Group CTRL
Before	7.40±0.52^a	7.30±0.48^a	7.40±0.52^b	7.30±0.48^a	7.10±0.32^a
After	7.10±0.32^a	7.50±0.53^a	5.90±0.74^a	7.40±0.52^a	7.20±0.42^a
30min	7.50±0.53^a	7.20±0.42^a	7.10±0.32^b	7.20±0.42^a	7.4.0±0.52^a

Phases with same letter at each stage have no statistically significant difference between themselves (Tukey's test, p>0.05).
