摘　　要：目的 :本实验通过检测 30名正畸成人患者与 30名非正畸成人对照组之间的龋活性差异 ,以了解成人正畸矫治与龋活性的关系。方法 :检测方法包括变形链球菌菌落数的测定、乳酸杆菌计数、细菌产酸能力的测定和唾液缓冲能力试验 ,采取SPSS10 .0统计分析软件包对资料进行统计处理 ,采用t检验进行统计学分析。结果 :正常成人组口腔内变形链球菌和乳酸杆菌数目明显少于正畸成人组 ,只有统计学差异 (P <0 .0 1)。而唾液 pH值和唾液缓冲能力两组间无统计学显著差异 (P >0 .0 5 )。结论Objective:To detect the caries activity of orthodontical treated and untreated adult.Methods:The study population consisted of 30 adults whose age are over twenty,the control group includes 30 adults who did not accept any orthodontical treatment.The detective methods were enumeration of streptococcus mutans in saliva,ability of plaque to produce acid and salivary buffering capacity.Student's test was used to analyse the statistical difference.Results:The results showed that the number of S.mutans and lactobacillus on the untreated group are much lower than that of the orthodontical group;the salivary pH,salivary buffering capacity and ability of germ to produce acid are similar between orthodontical treated and untreated adult.Conclusion:This study suggests that the orthodontical treated adult are more sensitive to dental caries than untreated adult.
