To assess the plaque and salivary pH changes at different time intervals in vivo after consumption of a carbonated beverage modified with sodium fluoride and calcium phosphate.
Twenty-four subjects aged 18-25 years were recruited and randomly assigned to three groups (group A, original drink Sprite; group B, Sprite with sodium fluoride; group C, Sprite with calcium phosphate). Collection of pooled plaque and unstimulated saliva was done before and after the drinks were consumed by the subjects at 5-, 10-, 20- and 30-minute intervals.
The pH rise was higher with group C for plaque and group B for saliva.
Modification of the test carbonated beverage with calcium phosphate and fluoride may exert some protective potential, especially in high caries risk candidates.
评估饮用添加了氟化钠和磷酸钙的碳酸饮料后，体内不同时间间隔菌斑和唾液pH值的变化。
招募24名年龄在18 - 25岁的受试者，随机分为三组（A组，原味饮料雪碧；B组，添加氟化钠的雪碧；C组，添加磷酸钙的雪碧）。在受试者饮用饮料前以及饮用后5分钟、10分钟、20分钟和30分钟时，收集混合菌斑和非刺激性唾液。
C组菌斑的pH值上升幅度更高，B组唾液的pH值上升幅度更高。
用磷酸钙和氟化物对测试碳酸饮料进行改良可能具有一定的保护潜力，尤其是对高龋齿风险人群。
