Mixed saliva and pooled plaque samples from the smooth surfaces of teeth were collected for microbiologic analysis before administration (baseline~ day 0).. during treatment (days 7.. 14 and 21) and after withdrawal of the agents (days 28~ 42 and 56) and plaque index were recorded. Microbial cultivation were performed by serially diluting the samples with PBS solution and cultivating the aiquots on Mitis Salivarius Agar and MS supplemented with bacitracin for Oral streptococci and Mutans streptococci respectively. The plates were incubated at 37~C under microaerophilic condition(90%N2,10%CO.,) for 48 hot:rs. The number of colony-forming unit per plate was counted and the percentage of Mutans Streptococci per Oral streptococci in dental plaque were determined.

使用前、使用中1、2、3周及停止使用后1、3、5周分别记录菌斑指数并收集唾液及光滑面集合菌斑样本，应用MS及MSB培养基微需氧环境培养检测唾液和菌斑中口腔链球菌属细菌及变形链球菌的菌落形成数，分析各组使用药物前后唾液中变形链球菌的改变及菌斑中变形链球菌在口腔链球菌属细菌中百分比的变化以及变化的延续性。

It was found that introducing 15 g/L additive containing 1.5 g saccharin helped to well retard electropolishing-induced corrosion of the electropolished improve the quality of the electropolished moldboard surfaces. At the same time, it was feasible to realize satisfactory precision electropolished of the laser moldboard made of stainless steel at a current density of 20~25 A/dm^2, duration of 1 min, and temperature of 60~65 ℃. The resulting polished moldboard had smooth walls and bright surface, while the corrosion was less than 0.005 mm.
