Effect on tooth discoloration from the coffee drink at various smoke disposal during coffee bean roasting

Research output: Contribution to journalConference articlepeer-review

Abstract

The Chlorogenic acid compound in a coffee bean can cause external discoloration of the tooth enamel. In general, external tooth discoloration is caused by deposition of a chromogenic agent into the enamel surface of the tooth. To know the tooth discoloration effects of various smoke disposal during coffee bean roasting, 18 tooth specimens were immersed in coffee solutions with varying roasting methods, including without smoke disposal, half-smoke disposal, and full-smoke disposal for 30, 45, or 60 hours. The color alteration was calculated with the CIE L∗, a∗, and b∗ formulae using the Vita Easyshade test machine. The results showed that the differences in tooth discoloration (E∗) among the solutions were not significant (p > 0.05). The mean E∗ values ranged from 10.23 to 17.67 and were not clinically significant. In conclusion, variations in the smoke disposal during coffee bean roasting did not affect tooth discoloration.
