The purpose of this study was to evaluate the effects of exposure to various children¡¯s drinks on the color stability of anterior primary teeth and different esthetic restorative materials clinically used in pediatric dentistry.

Exfoliated maxillary primary central incisors that had been unaffected by caries were chosen as control group. Maxillary primary central incisor-shaped specimens made of strip crown and Nu-smile zirconia crowns were chosen as test groups. Polished strip resin crowns were additionally prepared to compare with unpolished strip resin crown. Each specimen and teeth were divided into 4 groups in which the test samples (n=5 each) were immersed in 4 different drinks (distilled water, cola, grape juice, jelly juice) for 6 days.

In all 4 drink groups, all specimens generally showed increasing ¥ÄE* value (color difference) with time. Polished resin strip crown had higher ¥ÄE* value than the unpolished in cola, grape juice and jelly juice groups. ¥ÄE* value of zirconia crown in cola, grape juice and jelly juice groups were significantly different (p < 0.05).

In conclusion, dietary control of children¡¯s drinks is required for preventing discoloration of restorative materials.
