摘要
目的 :为探索研究简便的龋活跃性检测法 ,并证实其反映患龋现状及预测龋进展之可靠性和实用性。方法 :从碳源、氮源、微生物呼吸抑制剂、指示剂等选择研制有利致龋菌生长、显色鲜明的SCAT液剂 ,使菌斑样本经其恒温培养 ,依变色定高危、低危组。经 91名 2～ 4岁幼儿之检测 ,并追踪观察 2年 ,分析SCAT检测结果所表现的患龋现状和进展状态。结果 :患龋率、dft、CSI在SCAT所定之高危组均明显高于低危组 ;追踪 2年 ,新增之患龋率、dft、CSI在第 1年所定之高危组亦明显高于低危组。结论 :SCAT法操作简便 ,能反映患龋现状及预测龋病进展 ,可显示机体的龋活跃性。
Objective:To develop a simple caries activity test (SCAT ) and to prove its reliability in the caries examination and prognosis. M ethod:The SCAT solution chosen from the carbon source, nitrogen source and NaN 3 was used as indicator. Dental plaque sampes from 91 children aged 2～ 4 years were cultured with SCAT for 48 h. The high risk and low risk group were d etermined by the colour of the culture compared with that of the standard soluti on. Follow-up was conducted for 2 years. Results:The caries pr evalence, dft and CSI in the high risk group were significant higher than those in the low risk group (P<0.05). The development of caries prevalence ,dft a nd SCI in the high risk group were significant higher than those in the low ris k group in two years (P<0.05 or P<0 01). Conclusion:S CAT is feasible in the examination and progrosis of caries.
