치면세균막 제거 전후 착색된 치아의 색 평가 = The color evaluation for the discolored tooth before and after removal of dental plaque

다국어 초록 (Multilingual Abstract)

This in vitro study aimed to evaluate the color for the discolored tooth before and after removal of dental plaque. Eight bovine enamel specimens per beverage group were subjected to an 8-day pH-cycling model, which used six Korean children's beverages and a remineralizing solution.
The surfaces of the enamel specimens were photographed and evaluated the color at the following times. (1) sound teeth before the pH-cycling, (2) simply cleaned teeth after pH-cycling (bacterial membrane remain on the tooth surface), (3) ultrasonic cleaned teeth (complete removal of bacterial membrane from tooth surface). The color change (ΔE) was investigated between a simply cleaned teeth and a sound teeth (ΔESC), and ultrasonic cleaned teeth (ΔEUC) and sound teeth . The largest group with ΔESC and ΔEUC was in the coca-cola group, and the group showed a statistically significant difference for the ΔESC and ΔEUC between the other drink groups (p<0.05). There was also a significant difference between ΔESC and ΔEUC values in the coca-cola group (p<0.05).
However, this was not a clinically detectable color difference. In conclusion, dental bacterial membranes do not clinically affect tooth color evaluation.
