不同龋敏感人群唾液理化性质的比较

Comparison of salivary physicochemical properties between caries梐ctive and caries-free individuals.

对不同龋敏感人群唾液的分泌率、pH值、缓冲能力、粘度进行了比较.发现无龋组唾液分泌率、缓冲能力显著高于高龋组(P<0.02),无龋组唾液的粘度显著低于高龋组(P<0.01),两组间唾液pH值无显著性差异(P>0.05).以上结果提示唾液理化性质可能是影响龋病发生的重要因素之一.

Two groups of adults (age from 18 to 40), 22 caries-free (DFS = 0,CF)and 18 caries-active (DFS ≥6, CA), were investigated for stimulated parotid saliva. CF showed significantly higher values for the salivary secretion rate and buffer effect(P < 0.05)than CA did,but the viscosity of CF saliva was lower than that of CA(P<0.01).The statistical difference of pH value between two groups was not found.The results suggested that some of the salivary physicochemical properties might influence the procedure of caries.
