ΔTP₀₀ values of the composite resins after 14 days of immersion in different teas

Composite Resin	Distilled water	Black tea	Rooibos tea	Peppermint tea
Estelite Palfique Paste	−0.44 (−0.58—−0.17)^A,b	−4.08 (−5.13—−2.39)^D,a	−2.15 (−2.87—−1.69)^C,a	−0.69 (−1.00—−0.61)^B,b
Estelite Posterior	−0.13 (−0.26—−0.03)^A,a	−2.92 (−3.93—−2.63)^C,a	−2.00 (−2.15—−1.23)^B,a	−0.40 (−0.65—−0.06)^A,a

^*Values are presented as Median (Min–Max). Different uppercase letters within the same row indicate significant differences among tea groups for each composite resin (p <0.0083, Bonferroni−adjusted Mann–Whitney test). Different lowercase letters within the same column indicate significant differences between composite resins within the same tea group (p <0.0125, Bonferroni−adjusted Mann–Whitney test)
