摘要
目的 通过检测29名12～18岁固定矫正青少年的龋活性,了解固定矫正与龋活性的关系。方法 测定变形链球菌菌落数、菌斑产酸能力和唾液缓冲能力,用团体T检验的方法进行统计。结果 正常青少年对照组口腔内变形链球菌菌落数明显少于固定矫正青少年组,而唾液PH值明显大于固定矫正组,统计学上有显著性差异(P<0.01)。两组菌斑产酸能力无统计学显著性差异,正常青少年唾液缓冲能力虽然高于固定矫正组,但两组之间无显著性差异(P<0.05)。结论 结果显示固定矫正青少年对龋病的易感性增加。
Objective To detect the caries activity of being orthodontically treated and untreated teenagers. Methods The study population consisted of 29 13-18-year-old teenagers. 29 teenagers were in control group. The detective was enumeration of streptococcus mutans in saliva, ability of plaque to produce acid and salivary buffering capacity. Study' test was used to analyse statistical difference. Results The results showed that the number of S. mutans on the untreated group was much lower, than that of the orthodontic group, the salivary PH of the control group was higher than the orthodontic group. The diference was statistically significant (P<0.01). The ability of plaque to produce acid and salivary buffering capacity was similar between orthordontically treated and untreated teenagers. Conclusion The results suggest that the orthodontically treated teenagers are more sensitive to dental caries than untreated teenagers.
