This study examined the correlation between dark pigmented dental plaque (black stain) and caries. Black stain was observed in 67 of 1086 schoolchildren (from 6-12 years old). The mean DMF-T was 0.49 = 1.05 for children with black stain and 0.97 = 1.40 for children with black without black stain (p<0.05). The results suggest an association between black stain and a decreased caries experience at least in the permanent dentition. Further studies are necessary to examine the etiology and whether or not black stain can protect against caries.
本研究调查了深色牙菌斑（黑斑）与龋齿之间的相关性。在1086名6至12岁的学童中，有67人观察到有黑斑。有黑斑儿童的平均龋失补牙面数（DMF-T）为0.49±1.05，无黑斑儿童的平均DMF-T为0.97±1.40（p<0.05）。结果表明，至少在恒牙列中，黑斑与龋齿发生率降低之间存在关联。有必要进一步研究其病因以及黑斑是否能预防龋齿。
