The aim of the present study was to evaluate the reproducibility of the caries risk test Clinpro Cario L-Pop (3 M Espe, D-Seefeld), which measures the lactic acid produced by different bacteria of the oral flora, under stable oral conditions. In a group of healthy volunteers (n=31), the test was carried out ten times during 2 weeks. During the test period, the subjects were requested not to change their oral hygiene habits to ensure stable oral conditions. To register possible alterations of oral conditions by medication, a questionnaire was used. In subjects who did not alter their oral conditions (n=20), the reproducibility was 82.0%, with especially low score variations in subjects with low lactate signal scores. Some subjects exhibited, mainly due to colds and their medication, alterations in their oral conditions. The reproducibility in this group was 60.0%. Both reproducibility values differ significantly. In conclusion, the new diagnostic device shows high reproducibility under stable oral conditions. The lower reproducibility under altered oral conditions gives evidence that the test might reflect changes in the oral microflora following preventive interventions and thus could be used to monitor the effect of such interventions.
本研究的目的是评估龋病风险测试Clinpro Cario L-Pop（3M Espe，德国锡菲尔德）在稳定口腔条件下的可重复性，该测试可测量口腔菌群中不同细菌产生的乳酸。在一组健康志愿者（n = 31）中，该测试在2周内进行了10次。在测试期间，要求受试者不要改变其口腔卫生习惯，以确保口腔条件稳定。为了记录药物治疗可能引起的口腔条件变化，使用了一份问卷。在口腔条件未改变的受试者（n = 20）中，可重复性为82.0%，乳酸信号得分低的受试者得分变化尤其小。一些受试者主要由于感冒及其药物治疗，口腔条件发生了变化。该组的可重复性为60.0%。这两个可重复性值有显著差异。总之，这种新的诊断设备在稳定的口腔条件下显示出高可重复性。在口腔条件改变时可重复性较低，这表明该测试可能反映了预防性干预后口腔微生物群的变化，因此可用于监测此类干预的效果。
