The levels of salivary lactobacilli and yeasts were determined annually in half of the subjects of the xylitol (X) and fluoride (F) groups of a 3-year caries study. These measurements were carried out with Dentocult (DC) and Oricult (OC) dip-slide methods. A high level of lactobacilli prevailed throughout the study in these subjects. Significant changes were registered in some subgroups--that is, improvement in one of the X institutions and worsening in one of the F and one of the X institutions. At base line the counts of OC were worse in the X than in the F group. In the total material some improvement occurred during the course of the study, mainly in the X group. The changes associated with the preventive program should also be considered as related to the improvement in oral hygiene, restorative treatment, and the mere study effect.
在一项为期3年的龋齿研究中，每年对木糖醇（X）组和氟化物（F）组一半的受试者进行唾液中乳酸杆菌和酵母菌水平的测定。这些测量采用Dentocult（DC）和Oricult（OC）浸片法进行。在整个研究过程中，这些受试者的乳酸杆菌水平一直较高。在一些亚组中出现了显著变化，即在一个X组机构中有所改善，而在一个F组机构和一个X组机构中则有所恶化。基线时，X组的OC计数比F组差。在整个研究材料中，研究过程中出现了一些改善，主要在X组。与预防计划相关的变化也应被视为与口腔卫生改善、修复治疗以及单纯的研究效应有关。
