Tóm tắt

 OBJECTIVE: This study evaluated the impact of dentifrices containing amine fluoride (AmF) and/or tin on tooth discoloration and surface roughness under cycles of staining and abrasion. MATERIALS AND METHODS: Specimens of enamel (n = 10) and dentin (n = 19) were allocated into six groups: (1) Negative control (Distilled water), (2) NaF (regular fluoridated dentifrice without amine and tin), (3) AmF, (4) AmF/NaF/SnCl RESULTS: For enamel, no significant differences in ΔE were observed among groups
  however, for dentin, AmF exhibited the highest ΔE value, differing from all groups except Negative control (p >
  0.05). Both substrates showed a decrease in luminosity (-ΔL), with significant differences in dentin for the AmF group (p <
  0.05). For dentin, all groups showed an increase in tooth yellowness (+Δb)
  while for enamel, only the tin-containing groups showed this effect. All groups showed an increase in surface roughness after cycling. Enamel Ra showed significant differences post-treatment, with AmF differing from NaF/AmF/SnCl CONCLUSIONS: Brushing with AmF/NaF/SnCl CLINICAL SIGNIFICANCE: Some components in dentifrices can induce tooth discoloration, which seems to impact dental aesthetics
  therefore, clinicians should advise patients on potential color alterations when choosing specific dentifrice products.
