OBJECTIVE
This in situ/ex vivo study assessed the erosive potential of a light cola drink when compared to a regular one.
METHODS
During 2 experimental 14-days crossover phases, eight volunteers wore palatal devices with 2 human enamel blocks. The groups under study were: group light, erosive challenge with light cola drink and group regular, erosive challenge with regular cola drink. During 14 days, erosive challenges were performed extraorally 3X/day. In each challenge, the device was immersed in 150ml of light cola (group light) or regular cola (group regular) for 5min. Erosion was analysed by surface profilometry (microm) and surface microhardness change (%SMH). The data were statistically analyzed using paired t test (p<0.05).
RESULTS
Group light (0.6+/-0.2microm) showed significantly lesser wear than group regular (3.1+/-1.0microm). There was no significant difference between the groups for the %SMH (group light -63.9+/-13.9 and group regular -78.5+/-12.7).
CONCLUSIONS
The data suggest that the light cola drink is less erosive than the regular one.
目的
本原位/离体研究评估了低热量可乐饮料与普通可乐饮料相比的侵蚀潜力。
方法
在两个为期14天的实验交叉阶段，8名志愿者佩戴带有2个人类牙釉质块的腭部装置。研究组包括：低热量组，用低热量可乐饮料进行侵蚀挑战；普通组，用普通可乐饮料进行侵蚀挑战。在14天内，每天在口外进行3次侵蚀挑战。每次挑战时，将装置浸入150毫升低热量可乐（低热量组）或普通可乐（普通组）中5分钟。通过表面轮廓测量法（微米）和表面显微硬度变化（%SMH）分析侵蚀情况。使用配对t检验对数据进行统计学分析（p<0.05）。
结果
低热量组（0.6±0.2微米）的磨损明显低于普通组（3.1±1.0微米）。两组之间的%SMH没有显著差异（低热量组-63.9±13.9，普通组-78.5±12.7）。
结论
数据表明低热量可乐饮料的侵蚀性低于普通可乐饮料。
